Answer:

-29.96

Step-by-step explanation:

You add both numbers, as both are negative, and you get the answer.

The plant grew by approximately 41.75 centimeters in the following three weeks.

The initial height of the plant was 133 centimeters. After one week, it grew by 37 centimeters, so its height became:

133 + 37 = 170 centimeters

After three more weeks, the new height was 238 centimeters. If we subtract the initial height (133 centimeters) from the final height (238 centimeters), we can find the total growth in four weeks:

238 - 133 = 105 centimeters

We can then subtract the growth in the first week (37 centimeters) to find the growth in the following three weeks:

105 - 37 = 68 centimeters

Therefore, the plant grew by 68 centimeters in three weeks.

Alternatively, we can find the average growth rate per week by dividing the total growth in four weeks by the number of weeks:

(238 - 133) / 4 = 26.25 centimeters per week

Multiplying the growth rate by the number of weeks in the following three weeks, we can find the expected growth in that period:

26.25 * 3 = 78.75 centimeters

Subtracting the initial growth from the expected growth, we can find the growth in the following three weeks:

78.75 - 37 = 41.75 centimeters

Step-by-step explanation:

1.The machine will have no value after 48 months. 2.The graph of the machine's value over time will be a straight line. 3.The slope of the graph represents the rate of depreciation per month. 4.The intercepts of the graph indicate the initial value and zero value. 5.The expression V = -750x + 28,000 represents the value of the machine. 6.The machine has no value when x = 37 according to the expression. 7.The answer obtained using the expression differs from the answer in 8.question 1 due to possible rounding errors or calculation variations.

To determine when the machine has no value, we observe the pattern of depreciation. Based on the given data, the machine depreciates by $3,500 every 6 months. Therefore, it will take 48 months (8 cycles of 6 months) for the machine to have no value.

The table shows a consistent decrease in value over time with equal intervals of 6 months. This indicates a linear relationship between the number of months and the value. A linear relationship is represented by a straight line on a graph.

The slope of the graph can be determined by calculating the change in value divided by the change in time. In this case, the slope is (-750), meaning the value decreases by $750 per month. It represents the rate of depreciation per month.

The intercepts of the graph are obtained by determining the value of the machine at the start (initial value intercept) and when it reaches zero (zero value intercept). The initial value intercept is $28,000, which represents the starting value of the machine. The zero value intercept occurs when the machine has no value.

The expression V = -750x + 28,000 represents the value of the machine. The coefficient of x (-750) represents the rate of depreciation per month, while the constant term (28,000) represents the initial value.

Using the expression, when x = 37, the machine has no value. This differs from the answer in question 1 (48 months). The discrepancy could be due to rounding errors or variations in the method used to calculate the exact point at which the value reaches zero.

Since the sum of the numbers selected must exceed 1, we know that n must be at least 1. Therefore, the expected value of X is finite and is equal to 2.

The expected value of the count of numbers that are selected can be found using the geometric distribution, since it models the number of trials until a success occurs.

Let X be the number of numbers that are selected until the sum of all numbers exceeds 1. Then X has a geometric distribution with parameter p, where p is the probability of success on each trial, i.e. the probability that the sum of all numbers selected does not exceed 1.

Since the numbers are selected uniformly over [0, 1], the probability of success on each trial is given by the area under the curve between 0 and 1 after the first number is selected.

On the first trial, the probability of success is 1. On the second trial, the probability of success is the area under the curve between 0 and (1 - the first number selected).

On the third trial, the probability of success is the area under the curve between 0 and (1 - the sum of the first two numbers selected), and so on.

The expected value of X can be found using the formula for the expected value of a geometric distribution:

E(X) = 1/p

Since the expected value of the sum of n independent and identically distributed uniform [0, 1] random variables is n/2, we can use this to find p:

E(X_1 + X_2 + ... + X_n) = n/2

where X_1, X_2, ..., X_n are the n numbers selected.

So, p = 1 / (1 + n/2).

Finally, we can substitute this into the formula for E(X) to find the expected value of X:

E(X) = 1 / (1 - n/2) = 2 / (2 - n)

The equation of linear function which relate y to x is,

⇒ y = - 4x - 2

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (- 2, 6) and (- 1, 2).

Now,

Since, The equation of line passes through the points (- 2, 6) and (- 1, 2).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (2 - 6) / (- 1 - (-2))

m = - 4 / 1

m = - 4

Thus, The equation of line with slope - 4 is,

⇒ y - 6 = - 4 (x - (-2))

⇒ y - 6 = - 4 (x + 2)

⇒ y = - 4x - 8 + 6

⇒ y = - 4x - 2

Therefore, The equation of linear function which relate y to x is,

⇒ y = - 4x - 2

The answer which we get after calculating from the data given is that  Larry has 15 dollars more than Lenny.

Let the amount which Lenny is having be x

then the amount which Larry is having will be (2/5)x

and on combining them it makes $35 .

Which means,  x + 2x/5 = 35

On simplifying this equation we will get ,

(7/5)x= 35   ,

multiplying both the sides by 5/7

x= (5/7)*35 = $25

Therefore , Lenny is having 4 25.

Step-by-step explanation:

8.

the angle at a vertex (crossing point) outside of the circle (when both lines intersect with the circle arc, which is also the case for tangents) is half of the difference of both arc angles (the outer and the inner angles).

the outer angle is 250°. since the full circle is 360°, this makes the inner arc angle 360-250 = 110°.

the difference is 250-110 = 140.

and half of that difference is

140/2 = 70°.

so, x = 70°

9.

see 8.

the angle at the vertex outside the circle is half of the difference between outer and inner arc angle.

in fact, this is again about tangents (despite the picture), because the outer angle + the inner angle is again 360° (the full circle). this can only be, if the 2 lines are tangents splitting the outer and inner arc angles into 2 parts of 360° without remainder.

320 - 40 = 280

280/2 = 140

x = 140°

10.

see 8. and 9.

it is an extreme example, where the vertex of the 2 intersecting lines is exactly on the circle arc and the tangent point of the second line.

this makes the inner arc angle = 0°.

remember, the vertex angle (55°) is half of the difference of the outer (x) and inner (0°) arc angle.

55 = (x - 0)/2

110° = x

11.

remember the table question, where we found that the circle internal angle of 2 intersecting lines is half of the sum of both intersected arc angles ?

this is exactly this case again.

(120 + 50)/2 = 170/2 = 85°

x = 85°.

12.

first, like in 8. and 9., we determine the vertex angle. x is then the supplementary angle (together they have 180°) to this vertex angle, because the sum of all angles around one point on one side of a line is always 180°.

the vertex angle is

(125 - 15)/2 = 55°

x + 55 = 180

x = 125°.

13.

see 11.

the circle internal vertex angle is half of the sum of both circle arcs.

x = (70 + 30)/2 = 100/2 = 50°.

14.

again, an extreme case, where the vertex is on the circle arc. so, the second arc angle is 0°.

see also 12.

x is the supplementary angle of the vertex angle.

the vertex angle is

(80 + 0)/2 = 80/2 = 40°.

x + 40 = 180

x = 140°.

15.

it is difficult to read. I see the outer arc circle as 140°.

see 8., 9., 10.

the vertex angle x is

x = (140 - 70)/2 = 70/2 = 35°

do I sound like a broken record ? I at least feel that way. you should be able to apply the explanations from the previous questions to solve the new ones yourself.

$1875 has accrued in Latasha's savings account

$11,875 is the total amount in Latasha's savings account after 5 years

The tenth position is the one that goes after the decimal point.

To round a number, you have to take into account the following:

1. If the number that goes after the position we are going to round to is greater than 5, we round to the next number in that position.

2. If the number that goes after the position we are going to round to is less than 5, we round to the same number in that position.

In this case, the number that is on the tenth's position is 4. The number that is after this position is 1, which is less than 5, then we round the number in this positon to 4.

The rounded number would be:

The ΔH values associated with the dissolution of lithium chloride that are exothermic involve the release of heat energy. When a substance dissolves in a solvent, it can either release heat (exothermic) or absorb heat (endothermic).

Here are the steps to determine if the dissolution of lithium chloride is exothermic:

1. Look for the chemical equation that represents the dissolution of lithium chloride. In this case, it would be:

LiCl(s) → Li+(aq) + Cl-(aq)

2. Examine the enthalpy change (ΔH) associated with this chemical equation. If the ΔH value is negative, it indicates an exothermic process, meaning that heat is released during the dissolution. If the ΔH value is positive, it indicates an endothermic process, meaning that heat is absorbed during the dissolution.

So, to identify the exothermic ΔH values associated with the dissolution of lithium chloride, you need to find experiments or reliable sources that provide the enthalpy change values for this reaction.

Answer:

1.5 is not a repeating decimal, and 1 1/2

Step-by-step explanation:

The standard matrix of a linear transformation T can be found by using the formula A = [T(e1) T(e2) ... T(en)], where A is the standard matrix, e1, e2, ..., en are the columns of the identity matrix, and T(e1), T(e2), ..., T(en) are the images of the identity matrix columns under the transformation T.

1. For the first transformation, the standard matrix of T can be found by using the formula A = [T(e1) T(e2)] = [(3,1,3,1) (-5,2,0,0)] = [[3 -5] [1 2] [3 0] [1 0]]. Therefore, the standard matrix of T is [[3 -5] [1 2] [3 0] [1 0]].

2. For the second transformation, the standard matrix of T can be found by using the formula A = [T(e1) T(e2) T(e3)] = [(1,3) (4,-7) (-5,4)] = [[1 4 -5] [3 -7 4]]. Therefore, the standard matrix of T is [[1 4 -5] [3 -7 4]].

3. For the third transformation, the standard matrix of T can be found by using the formula A = [T(e1) T(e2)] = [cos(31/2) -sin(31/2) sin(31/2) cos(31/2)], where cos(31/2) and sin(31/2) are the cosine and sine of 31/2 radians, respectively. Therefore, the standard matrix of T is [cos(31/2) -sin(31/2) sin(31/2) cos(31/2)].

4. For the fourth transformation, the standard matrix of T can be found by using the formula A = [T(e1) T(e2)] = [cos(-1/4) -sin(-1/4) sin(-1/4) cos(-1/4)], where cos(-1/4) and sin(-1/4) are the cosine and sine of -1/4 radians, respectively. Therefore, the standard matrix of T is [cos(-1/4) -sin(-1/4) sin(-1/4) cos(-1/4)].

5. For the fifth transformation, the standard matrix of T can be found by using the formula A = [T(e1) T(e2)] = [(1,0) (2,1)] = [[1 2] [0 1]]. Therefore, the standard matrix of T is [[1 2] [0 1]].

6. For the sixth transformation, the standard matrix of T can be found by using the formula A = [T(e1) T(e2)] = [(1,0) (3,1)] = [[1 3] [0 1]]. Therefore, the standard matrix of T is [[1 3] [0 1]].

The probability of getting a marble marked with a number greater than 4 is \(\frac{1}{9}\).

Probability is the measure of happening or non-happening of outcomes of random experiment.

P(E) = Number of favorable outcomes/Total number of outcomes

where,

P(E) is the probability of an event.

According to the given question.

Total number of marbles in jar = 18

⇒ Total number of outcomes = 18  

( 6 red marbles, 6 black marbles, and 6 green marbles)

But it is given that, black or red marble is randomly selected.

Therefore, the total number of outcomes reduced to 12.

Numbers which are greater than 4 among 1 to 6 are 5 and 6.

Total number of numbers which are greater than 4 in jar = 2 × 3 =6

But we have to select only black or red marble.

Therefore,

Total number of favorable outcomes = 4

The probability of selecting a marble greater than 4 which are red

= \(\frac{4}{12} =\frac{1}{3}\)

The probability of selecting a marble greater than 4 which are black

= \(\frac{4}{12} = \frac{1}{3}\)

Therefore, the probability of getting a marble marked with a number greater than 4 \(=(\frac{1}{3}) (\frac{1}{3} )=\frac{1}{9}\)

Hence, the probability of getting a marble marked with a number greater than 4 is \(\frac{1}{9}\).

Correlated variables are two explanatory factors that are connected to both the response variable and each other. The statistical relationship between two variables, which shows how they change together, is referred to as correlation.

Explanatory variables are used in regression analysis to forecast or explain the response variable. A correlation between two explanatory variables indicates that changes in one are influenced by changes in the other. Understanding the relationship between the explanatory variables and the response variable can be significantly impacted by this correlation. When analysing data, it's crucial to take into account the presence of correlated variables in order to avoid problems like multicollinearity and properly interpret the analysis's findings.
