Answer:

The answer to this question is 9cm^2, the second answer

Step-by-step explanation:

To find the area of this parallelogram, you have to first find the area of one of the two triangles shown. The formula to solve a triangle is (base * height)/2, so that would be 4.5cm^2 for each triangle, times two for two triangles would be 9cm^2. If you wanted to do it an easier way, just multiply the length of the bottom of the parallelogram with the height. The measures telling you 3.5 are telling you the length of the diagonal line, so don't pay attention to that.  

Answer:

Rs. 22,080.

Step-by-step explanation:

Let the height be x m then the breadth is 3x and the length 5x m.

x * 3x * 5x = 960

15x^3 = 960

x^3 = 64

x = ∛ 64 = 4m.

Therefore the height is 4m, the breadth = 12 m and the length = 20m.

So the area of all the surfaces

= 2 * short wall + 2 * long wall + floor + ceiling

= 2 *4*12 + 2*4*20 + 12*20 + 12*20

=  96 + 160 + 240 + 240

= 736 m^2.

Cost plastering  = 736 * 30 = Rs. 22,080

Answer:

y = 7x - 4

Step-by-step explanation:

To solve the equation of this line ( in point - slope form ) we would have to first identify the slope. If we are given the points ( 0, - 4 ) and ( 1, 3 ) then through the change in y / change in x, we can calculate the value of this slope. Take a look at the steps below;

\(( 0, - 4 ), ( 1, 3 )\\\\Slope = y2 - y1 / x2 - x1,\\\\Slope = - 4 - 3 / 0 - 1,\\Slope = - 7 / - 1\\Slope = 7 / 1\\\\Slope = 7\)

Now that we have the slope of this line, we have assume part of the equation of this line ( that passes through the points ( 0, - 4 ) and ( 1, 3 ) );

\(y = mx + b -\\m = slope, b = y - intercept\)

Plug in the value of slope for " m " in y = mx + b, and determine the y - intercept by plugging in x as 0 and y as - 4, given the point ( 0, - 4 );

\(- 4 = 7 * ( 0 ) + b,\\- 4 = 0 + b,\\b = - 4\)

From this information, we can say that the equation of this line is y = 7x - 4;

Solution, y = 7x - 4

a.  the student must pay $2197.50 in interest. b.  the future value of the loan is $4197.50.

a. To calculate the interest, we can use the formula:

Interest = Principal x Rate x Time

Given:

Principal (P) = $2000.00

Rate (R) = 12.25% = 0.1225 (converted to decimal)

Time (T) = 9 months

Using the formula, we have:

Interest = $2000.00 x 0.1225 x 9

Interest = $2197.50

Therefore, the student must pay $2197.50 in interest.

b. To find the future value of the loan, we can use the formula:

Future Value = Principal + Interest

Given:

Principal (P) = $2000.00

Interest = $2197.50

Using the formula, we have:

Future Value = $2000.00 + $2197.50

Future Value = $4197.50

Therefore, the future value of the loan is $4197.50.

I HOPE IT WILL HELP YOU. I DID HOW I KNOW .

Answer:

  C.  142°

Step-by-step explanation:

You want the angle between vectors u=3i+√3j and v=-2i-5j.

There are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:

  u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest

You can find the angles of the vectors individually, and subtract those:

  u = |u|∠α

  v = |v|∠β

  θ = α - β

When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:

  \(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)

This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.

A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.

__

Additional comment

The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.

The dot-product relation will work with 3D vectors as well as 2D vectors.

The estimated regression equation that could be used to predict the percentage of games won, given the average number of passing yards per attempt, can be expressed as:

ŷ = β₀ + β₁x₁

Where: ŷ represents the predicted percentage of games won,

β₀ represents the y-intercept (constant term),

β₁ represents the coefficient for the average number of passing yards per attempt,

x₁ represents the average number of passing yards per attempt.

The proportion of variation in the sample values of the percentage of games won that this model explains is commonly measured by the coefficient of determination, denoted as R². This metric indicates the proportion of the total variation in the dependent variable (percentage of games won) that can be explained by the independent variable (average number of passing yards per attempt).

R² provides a value between 0 and 1, where 0 indicates that the independent variable does not explain any of the variation in the dependent variable, and 1 indicates that the independent variable perfectly explains all the variation. Generally, a higher R² value suggests a better fit of the regression model.

To determine the specific proportion of variation explained by this model, we would need additional information or statistical analysis using data. Without the specific data or analysis, it is not possible to provide a precise answer.

(a) The volume of the paint in the can is approximately 0.003086 cubic meters.

(b) The thickness of the layer of wet paint on the wall is approximately 0.06182 meters.

:(a) To convert the volume of the paint from gallons to cubic meters, we need to use the conversion factor 1 U.S. gallon = 0.00378541 cubic meters. Given that the paint can has 0.816 U.S. gallons of paint left, we can calculate the volume in cubic meters by multiplying 0.816 by the conversion factor. The result is approximately 0.003086 cubic meters.

(b) To find the thickness of the layer of wet paint on the wall, we need to divide the volume of the paint (in cubic meters) by the area of the wall (in square meters). The remaining paint can cover an area of 13.2 square meters, so dividing the volume of the paint (0.003086 cubic meters) by the wall area (13.2 square meters) gives us approximately 0.0002333 meters or 0.06182 meters when rounded.

Answer:

Below

Step-by-step explanation:

The picture is cut off....but I will assume the spinner has six equal spaces labeled A B C D and E

Landed on C  eight time during the experemental 30 spins

     the  experimental  prob is then   8 / 30 = 4/15

      the THEORETICAL prob would be 1/6 th of the 30 spins

                1/6 * 30 = 5 times

9) if it is a fair spinner, you would expect the Experimental outcome to approach closer to the theoretical prob as you spin more times

10) you would expect "C"  1/6th of the time:  1000 *1/6 = 166 2/3 times

          ( you cannot land on "C"  EXACTLY this many times...but it would be close if the spinner is fair)

11 )  red =~ 1/2/ of the spinner    Blue = 1/4    yellow = 1/4th of the spinner

         by the fractional outcomes given out of 40 spins

            (     red = 21/40 = ~ 1/2   etc  )

SOLUTION

The triangle in the picture has two sides to be equal. This means that the triangle is an isosceles triangle.

The base angles of an isosceles triangle are equal.

This implies that angle C = B = 49 degrees

So both angles B and C are 49 degrees each.

Now let's find angle A

A + B + C = 180 degrees (sum of angles in a triangle)

Then

The line bisects angle A into two equal triangles, that is angle y and the angle at the other side

This means that

Now let's find x.

Angles x, y, and B make up a triangle. This means that

Therefore, x = 90, and y = 41

The t-test assuming equal variances means Pooled t-test in which variances of the two sample populations are equal.

The pooled t-test is the statistical procedure that assumes that population variances are equal. Finding a weighted average of the two independent sample variances is referred to as pooling. By combining data from samples from populations 1 and 2, we may estimate the common variance when there is solid evidence that population 1's variance is equal to population 2's variance.

Compare the ratio of the two sample standard deviations as a quick way to verify this. The ratio would be compared as: S1/S2. The ratio would be 1, or, in the event that the two are equal.

However, we cannot anticipate the ratio to be exactly 1, as they are samples and as a result, there will be some errors. Thus, the pooled t-test implies whether the null-hypothesis should be accepted or rejected.

The the composition of f and g denoted by the expression (fg)(5) is equivalent to f(g(5))

The composition of two functions f and g is an operation where two functions f and g generates a new function h such that h(x)=f(g(x)).

First we find the value of g(x). If g(x)=y then f(g(x))=f(y).

The value of composition  (fg)(x) is equal to f(g(x)).

Thus the value of (fg)(5) is f(g(5)) .

The joint probability mass function (PMF) for the random variables x and y can be represented in a table with rows and columns corresponding to the possible values of x and y, respectively.

In this case, x represents the number of heads on the first toss, and y represents the total number of heads over all three tosses. There are two possible outcomes for each coin toss: heads (H) or tails (T). Thus, there are 2^3 = 8 possible outcomes for three coin tosses, which can be listed as follows: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT. For the first toss, there are two possible outcomes: H or T. Thus, x can take on the values x = 0 or x = 1, with probabilities P(x = 0) = 1/2 and P(x = 1) = 1/2.

For the total number of heads over all three tosses, there are four possible outcomes: 0, 1, 2, or 3 heads. The joint probabilities can be calculated by considering the possible outcomes for each value of x. For example, if x = 0 (i.e., the first toss is a tail), then y can only be 0 or 1, depending on the outcomes of the second and third tosses. The probabilities of these outcomes are P(x = 0, y = 0) = 1/8 and P(x = 0, y = 1) = 3/8. The joint probability mass function for x and y can be summarized in a table as follows:

Therefore , the solution of the given problem of percentage comes out to be 38 years old is the median age.

In statistics, a "a%" is a figure or statistic that is expressed as a percentage of 100. The words "pct," "pct," but instead "pc" are also not frequently used. However, the sign "%" is frequently used to represent it. The percentage sum is flat; there are no dimensions. Percentages are truly integers because their numerator almost always equals 100. Either the % symbol (%) or the additional term "fraction" must come before a number to denote that it is a percentage.

Here,

The following algorithm must be used to determine the mean age:

=> mean = (all years added together) / (total number of persons)

The representative age for each age group is the age that falls in the middle of the range. With this approach, we can determine the total age as follows:

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

=> 162 + 644 + 924 + 2970 + 4636 + 2688 + 1152 + 1520 + 272.25

=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)

According to the information provided, there are 460 people in total.

=> mean = 17745.25 / 460

=> mean = 17745.25 / 460

As a result, the average lifespan is roughly 38.552 years.

The age category in this instance with the highest frequency has a midpoint of 38 and a frequency of 122. As a result, 38 years old is the median age.
