Gavin was thinking of a number. Gavin adds 1, then divides by 7 to get an answer of -11. What was the original number?

The present value of $25,000 to be received in 5 years if the discount rate is 4% will be $20,555. The formula for calculating the future value of money (FV) is:

FV = PV x (1 + i)ⁿ where PV = present value, i = interest rate (in decimals) and,n = number of years.So, we need to calculate the future value of the deposit after 4 years, given the present value (PV) as $20,000 and interest rate (i) as 1.4%.

FV = $20,000 x (1 + 1.4%)⁴

FV = $20,000 x 1.014⁴

FV = $22,574.49.

Therefore, the future value of the deposit will be $22,574.49 after 4 years. Rounding it to the nearest whole number, the amount will be $22,574.2.

The formula for calculating the present value of money (PV) is:

PV = FV / (1 + i)ⁿ where FV = future value, i = interest rate (in decimals) and, n = number of years.So, we need to calculate the present value of $25,000 to be received in 5 years, given the interest rate (i) as 4%.

PV = $25,000 / (1 + 4%)⁵

PV = $25,000 / 1.2167

PV = $20,554.66

Therefore, the present value of $25,000 to be received in 5 years if the discount rate is 4% will be $20,554.66. Rounding it to the nearest whole number, the amount will be $20,555.

Answer:

45/8 or 5 5/8

Step-by-step explanation:

2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8.  you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.

Answer:

45/8 or 5 5/8

Step-by-step explanation:

When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.

Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.

                                      Numerators: 9 x 5 = 45

                                      Denominators: 4 x 2 = 8

So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

I don't know how you wanted me to show my work, but I tried the best I could to explain.

In scientific practice, we often use statistical inference to make conclusions about a population based on a sample. The use of confidence intervals is one method of making these inferences. A single 95% confidence interval can be interpreted as follows: we are 95% confident that our interval is one that contains the true population parameter.

This means that if we were to repeat the study many times, we would expect the true population parameter to be within our interval 95% of the time.
It is important to note that this interpretation assumes that the sample was selected randomly and that the assumptions for the statistical test used to construct the interval were met. Additionally, it is important to recognize that the interval is not a guarantee of the true population parameter being within it, but rather a range of values that is likely to contain the true parameter.

Overall, a single 95% confidence interval is a useful tool for making inferences about a population based on a sample, and it provides a range of values that we can be reasonably confident contains the true parameter.

Answer:

Step-by-step explanation:

The null hypothesis, H0: 2 = 0, states that the coefficient 2 has no effect on the expected value of y. This means that the expected value of y does not change when x2 is changed.

Mathematically, this can be expressed as:

E[y|x2] = E[y]

Where E[y|x2] is the expected value of y when x2 is given, and E[y] is the expected value of y when x2 is not given.

The equation for y can be rewritten as:

y = 1x1 + 0x2 + u

Where 0 is the coefficient of 2 when the null hypothesis is true. This equation can be further simplified to:

y = 1x1 + u

The equation now shows that x2 has no effect on the expected value of y. This is because the coefficient of x2 is 0, meaning that no matter what value x2 is given, it will not affect the expected value of y. Therefore, the null hypothesis, H0: 2 = 0 states that x2 has no effect on the expected value of y.

The probability that at least one box in a selection of three candy gift boxes will weigh less than 34 ounces needs to be found.

To calculate the probability, the weight of a box can be considered as the sum of the weights of the individual candies in the box. The weights of the individual candies are normally distributed with known means and standard deviations.

Using the properties of normal distributions, the weights of the boxes can be modeled as normally distributed with a mean of 27 ounces (9 candies x 3 ounces per candy) and a standard deviation of 0.374 ounces (sqrt(4*(0.2^2)+5*(0.3^2)+0.1^2)). Then, the probability of at least one box weighing less than 34 ounces can be calculated using the normal distribution function.

The calculated probability is 0.0569, or approximately 5.69%. Thus, there is a 5.69% chance that at least one of the three selected candy gift boxes will weigh less than 34 ounces.

The probability that at least one box will weigh less than 34 ounces is approximately 0.117.

To solve this problem, we can use the Central Limit Theorem to approximate the distribution of the total weight of three gift boxes. The mean weight of one gift box is 3*(4)+5*(3) = 27 ounces, and the standard deviation is sqrt((4*(0.2)^2 + 5*(0.3)^2)) = 0.69 ounces.

The probability that one gift box weighs less than 34 ounces is given by the standard normal distribution, which we can find using a z-score of (34-27)/0.69 = 10.14.

The probability that all three boxes weigh at least 34 ounces is (1-0.117)^3 = 0.770, so the probability that at least one box weighs less than 34 ounces is approximately 1 - 0.770 = 0.117.

Answer:

The speed of the slower train is 60km/hr or 80km/hr and the speed of the faster train is 70km/hr or 90km/hr.

There are 60 minutes in one hour. 3 hours would be equal to 180 minutes.

How many minutes are in 3 hours?

To convert hours to minutes, we need to consider that there are 60 minutes in one hour. In this case, since we have 3 hours, we can multiply 3 by 60 to get the equivalent number of minutes.

By performing the calculation, we find that 3 hours is equal to 180 minutes. This means that if you were to measure a time period of 3 hours, it would be equivalent to 180 minutes on the clock.

Understanding this conversion is useful when dealing with time-related calculations, such as scheduling events or determining durations. It allows us to easily switch between hours and minutes to represent time in different formats.

3 hours can be expressed as 180 minutes, demonstrating the relationship between hours and minutes in the context of time measurement.

Answer:

a) y = 2x + 12. b) y = -1/2 x  -1/2.

Step-by-step explanation:

a) parallel to will have same gradient, ie gradient of 2.

y - y1 = m(x - x1)

y1 is y-coordinate of point, x1 is x-coordinate of point, m is gradient.

y - 2 = 2(x - -5) = 2 (x + 5) = 2x + 10

y = 2x +10 + 2

y = 2x + 12

b) gradient of perpendicular = -1/m = -1/2.

y - 2 = -1/2 (x - -5) = -1/2 (x + 5) = -1/2 x - 5/2

y = -1/2x  -5/2 + 2

y = -1/2 x  -1/2

Therefore, the solution to the matrix equation with d = 2 is: x₁ = 6; x₂ = -1; x₃ = -6.

To determine the number d that forces a row exchange, we need to find a value for d that makes the coefficient in the pivot position (2,2) equal to zero. In this case, the pivot position is the (2,2) entry.

From the given matrix equation:

1 3

1 -2

d 0

To force a row exchange, we need the (2,2) entry to be zero. Therefore, we set -2 + d = 0 and solve for d:

d = 2

By substituting d = 2 into the matrix equation, we have:

1 3

1 2

2 0

To solve the matrix equation, we perform row operations:

R₂ = R₂ - R₁

R₃ = R₃ - 2R₁

1 3

0 -1

0 -6

Now, we can see that the matrix equation is in row-echelon form. By back-substitution, we can solve for the variables:

x₂ = -1

x₁ = 3 - 3x₂

= 3 - 3(-1)

The equation of the line that passes through (-5,9) and (8,-9) is y = -18/13x  + 27/13

When we are given two points then the formula for the equation of line or slope-intercept form is

                         (y-y1) = m(x-x1)          (1)

              Where (x1,y1) are the coordinates of a point

                            m = slope of the line

and the formula to find the slope is given as:

                           m = (y2-y1)/(x2-x1)          (2)

In the given question we have been given the two coordinates which are:

        (x1,y1) = (-5,9)  and  (x2,y2) = (8,-9)

Thus we will put the required value of (x1,y1) and (x2,y2) in equation (2) to find the value of slope.

                    m = (-9-9)/(8+5)

                    m = -18/13

Now we will put the value of slope in equation (1) and find the required equation of line,

           (y-9) = -18/13(x+5)

            y-9 = -18/13x – 90/13

            y = -18/13x  + 27/13

Hence equation of the line is              y = -18/13x  + 27/13

From the given set of numbers we have to arrange them in the increasing order.

{\(\sqrt{72},9.25,\sqrt{83},\pi^2,8.7\)}

Since, \(\sqrt{72}=8.49\)

\(\sqrt{83}=9.11\)

\(\pi ^2\) = 9.87

Therefore, set of numbers will be in the form of,

{8.49, 9.25, 9.11, 9.87, 8.7}

Now arranging these numbers in the increasing order,

8.49 < 8.7 < 9.11 < 9.25 < 9.87
