The linear equation is y= 6/8x + 16.

Looking at the given points, we can see that there is a positive correlation between x and y values.

The slope of the line should be positive.

Calculating the slope between two points, say (32, 40) and (40, 46):

Slope (m) = (change in y) / (change in x)

= (46 - 40) / (40 - 32)

= 6 / 8

We can observe that the slope is 3/4.

So, the linear equation is

y - 40 = 6/8 (x - 32)

y - 40 = 6/8 x  -24

y = 6/8x + 16

The equation -x + y = 5 can be represented in the y = mx + b form as y = x + 5. This form allows us to easily identify the slope and y-intercept of the line represented by the equation.

To express the equation -x + y = 5 in the y = mx + b form, we need to isolate y on one side of the equation.

Starting with -x + y = 5, we can rearrange the equation by moving the -x term to the other side:

y = x + 5

Now the equation is in the form y = mx + b, where m represents the slope and b represents the y-intercept.

In this case, the coefficient of x is 1, which gives us a slope of m = 1. This means that for every unit increase in x, y will increase by 1. The positive slope indicates that the line will slant upward as we move from left to right.

The constant term in the equation is 5, which gives us the y-intercept, b = 5. The y-intercept is the value of y when x is 0, which in this case is the point (0, 5) on the y-axis.

In the y = mx + b form, the equation -x + y = 5 can be written as y = x + 5. We can quickly determine the slope and y-intercept of the line that the equation represents using this method.

Answer:

the z score is 25

Step-by-step explanation:

since 75 needs 25 more for and 100%

The z-score of Bob if he scored 75 on a test that has a mean of 75 is: z-score = 0.

The z-score = (raw score - mean score)/standard deviation.

A z-score of 0 means the raw score is exactly average.

For a raw score of 75, where the average(mean) is 75, the z-score would definitely be 0.

The equation of the line in point-slope form is:

y - 8 = 3(x + 6) or y - 2 = 3(x + 8).

The equation, y - b = m(x - a), represents the equation of a line in point-slope form, where:

Given two points, (-8, 2) and (-6, 8), find the slope (m) of the line that passes through the two points:

Slope (m) = change in y / change in x = (8 - 2)/(-6 -(-8))

Slope (m) = 6/2

Slope (m) = 3

Substitute m = 3 and (-6, 8) into y - b = m(x - a):

y - 8 = 3(x - (-6))

y - 8 = 3(x + 6)

Or substitute m = 3 and (-8, 2) into y - b = m(x - a):

y - 2 = 3(x - (-8))

y - 2 = 3(x + 8)

Therefore, the equation of the line in point-slope form is:

y - 8 = 3(x + 6) or y - 2 = 3(x + 8).

The correct answer is Length of arc XY: 15.03 units.Area of shaded sector XY: 15.73 square units.

To complete the statements, we can use the properties of circles and the given information.

The length of the arc XY, denoted as "s," can be found using the formula:

s = (θ/360) * 2πr

where θ is the central angle in degrees and r is the radius of the circle.

Given that the central angle is 225° and the circumference of the circle is 30 units, we can solve for the radius (r):

Circumference = 2πr

30 = 2πr

r = 30 / (2π) ≈ 4.77 units (rounded to the hundredths place)

Now we can calculate the length of the arc XY:

s = (225/360) * 2π * 4.77 ≈ 15.03 units (rounded to the hundredths place)

Therefore, the length of the arc XY is approximately 15.03 units.

The area of the shaded sector XY, denoted as "A," can be found using the formula:

A = (θ/360) * πr²

Using the same values for θ and r as above, we can calculate the area:

A = (225/360) * π * (4.77)² ≈ 15.73 square units (rounded to the hundredths place)

Therefore, the area of the shaded sector XY is approximately 15.73 square units.

In a cubic polynomial function f is defined by f(x) = 4x³ + ax² + bx + k, where a, b, k, are constants and has a local minimum at x = -2 and a local maximum at x = 0, then values of a and b is 12 and 0 respectively. If integrate of f(x)dx = 32 from 0 to 1, then value of k is 27.

The given cubic polynomial function is

f(x) = 4x³ + ax² + bx + k

f'(x) = 12x² + 2ax + b

f''(x) = 24x + 2a

At local maximum f' = 0

f'(0) = 12×(0)² + 2a×(0) + b = 0

b = 0

At local minimum, f' = 0

That is f'(-2) = 0 and f''(-2) > 0

f'(-2) = 12×(-2)² + 2a×(-2) + b = 0

48 - 4a + b = 0

4a - b = 48  

a = 12

Therefore, f(x) =  4x³ + 12x² + k

Integrate f(x)dx = 32 from 0 to 1, that is

∫₀¹ f(x)dx = 32

∫₀¹ (4x³ + 12x² + k) dx = 32

[ x⁴ + 4x³ + kx ]₀¹ = 32

A significance level of 0.10, we have enough evidence to conclude that the new copy machines have a significantly faster mean repair time compared to the older model.

To test if the new copy machines are faster to repair, we can set up the following null and alternative hypotheses:

Null Hypothesis (H₀): The mean repair time for the new copy machines is the same as the mean repair time for the older model.

Alternative Hypothesis (H₁): The mean repair time for the new copy machines is less than the mean repair time for the older model.

Let's perform a one-sample t-test to test these hypotheses. The test statistic is calculated as:

t = (sample mean - population mean) / (sample standard deviation / √(sample size))

Given:

Population mean (μ) = 93 minutes

Sample mean (\(\bar x\)) = 86.8 minutes

Sample standard deviation (s) = 14.6 minutes

Sample size (n) = 18

Significance level (α) = 0.10

Calculating the test statistic:

t = (86.8 - 93) / (14.6 / sqrt(18))

t = -6.2 / (14.6 / 4.24264)

t ≈ -2.677

The degrees of freedom for this test is n - 1 = 18 - 1 = 17.

Now, we need to determine the critical value for the t-distribution with 17 degrees of freedom and a one-tailed test at a significance level of 0.10. Consulting a t-table or using statistical software, the critical value is approximately -1.333.

Since the test statistic (t = -2.677) is less than the critical value (-1.333), we reject the null hypothesis.

The company should use a warranty period that is equal to 67,467.5 miles.

To determine the warranty period, we need to find the value of the tire life that corresponds to 95% of the tires. We can use the standard normal distribution table to find the value of the z-score that corresponds to the 95th percentile. This value is approximately 1.645.

Now, we can use the formula for the normal distribution to find the tire life value that corresponds to the z-score of 1.645. This formula is:

X = μ + zσ

Where X is the tire life value, μ is the mean of the distribution (65,000 miles), z is the z-score (1.645), and σ is the standard deviation of the distribution (1500 miles).

Plugging in the values, we get:

X = 65,000 + 1.645(1500)

X = 67,467.5

This means that 95% of the tires will have a life of at least 67,467.5 miles.

a) The accumulated amount or future value of investing $150 on the first day of each month at 6% compounded monthly for 40 years is $274,152.43.

b) , The future value of the investment after 40 years at an annual interest rate of 4%, compounded semi-annually, is $9,054.60.

a)

N = 40 years * 12 months = 480 months

I% = 6% per year / 12 months = 0.5% per month

PV = $0 (since we are not investing any money initially)

PMT = $150

FV = ?

P/Y = 1 (payments made monthly)

C/Y = 12 (compounded monthly)

Using the formula for future value of an annuity:

FV = PMT * ((1 + I%)^(N) - 1) / I%

FV = $150 * ((1 + 0.5%)^(480) - 1) / 0.5%

FV = $274,152.43

Therefore, the accumulated amount or future value of investing $150 on the first day of each month at 6% compounded monthly for 40 years is $274,152.43.


b)
Given information:

PV (present value) = $900

I% (annual interest rate) = 4%

P/Y (payments per year) = 1 (since the investment is compounded semi-annually)

C/Y (compounding periods per year) = 2

N (number of periods) = 40 years * 2 (since interest is compounded twice a year) = 80

Using the compound interest formula:

FV = PV * (1 + (I%/C/Y))^(N*C/Y)

FV = $900 * (1 + (4%/2))^(80*2)

FV = $900 * (1.02)¹⁶⁰

FV = $900 * 10.06

FV = $9,054.60


Therefore, the future value of the investment after 40 years at an annual interest rate of 4%, compounded semi-annually, is $9,054.60.

Answer: the smallest number out of the four is 0.13

Step-by-step explanation:

First, let's think about the number 13. It's a whole number and it's pretty big. It's definitely larger than the other numbers we're looking at today.

Next, let's take a look at 0.13. This number is a decimal, which means it's a number that has a whole number part and a fractional part. The whole number part is 0 and the fractional part is 13. So, 0.13 is smaller than 13.

Now, let's move on to 1.03. This is also a decimal and it's a little bit bigger than 0.13, but smaller than 13.

Finally, we have 1.3. This number is a decimal with a whole number part of 1 and a fractional part of 3. It is bigger than 0.13 and 1.03 but smaller than 13.

So, we can see that the smallest number out of the four is 0.13.
