Answer:

a. -5°F, -8°C, 40°F, 10°C

Step-by-step explanation:

-17°C is when F = 0, so -8°C is way higher than -5°F. -8°C comes right after, and 40°F is a bit lower than 10°C. You can convert F to C is °F = (C * 9/5) + 32 and you can convert C to F with (F -32) x 5/9

Step-by-step explanation:

Answer: To calculate the average cost per widget, we need to consider both the fixed costs and the variable costs.

Fixed costs: $34,000

Variable costs per widget: $5.00

Total costs = Fixed costs + (Variable costs per widget × Number of widgets)

Total costs = $34,000 + ($5.00 × 7,000)

Total costs = $34,000 + $35,000

Total costs = $69,000

Average cost per widget = Total costs / Number of widgets

Average cost per widget = $69,000 / 7,000

Average cost per widget ≈ $9.86

Therefore, the average cost per widget of producing 7,000 Wild Widgets is approximately $9.86.

Answer:

The measurement found using Ruler 1 is more accurate but less precise

Step-by-step explanation:

The test statistics do not lie in the rejection so the null hypothesis does not reject.

Here we have the following information:

\(\bar{x}_{1}=25.3, n_{1}=25, s_{1}=9, \bar{x}_{2}=20.5, n_{2}=23, s_{2}=8\)

Here degree of feedom will be

\(df=n_{1}+n_{2}-2=25+23-2=46\)

The critical values of t are: +/- 2.687

Rejection region:

If t < -2.687 and t > 2.687, reject H0

Pooled variance is :

\(s^{2}_{p}=\frac{(n_{1}-1)s_{1}^{2}+\left ( n_{2}-1 \right )s_{2}^{2}}{n_{1}+n_{2}-2}=72.8696\)

The standard error is

\(s_{M_{1}-M_{2}}=s_{p}\sqrt{\frac{1}{n_{1}}+\frac{1}{n_{2}}}=2.4664\)

and t-statistics will be

\(t=\frac{\bar{x}_{1}-\bar{x}_{2}}{s_{p}\sqrt{\frac{1}{n_{1}}+\frac{1}{n_{2}}}}=1.946\)

the best prediction possible for the number of times the spinner will land on yellow if it is spun 72 times is 12. This means that out of 72 spins,

how to solve probability

If the spinner has 12 equal parts and 2 of them are yellow, then the probability of the spinner landing on yellow is 2/12, or 1/6. This means that out of every 6 spins, we can expect the spinner to land on yellow once.

To find the best prediction for the number of times the spinner will land on yellow if it is spun 72 times, we can use the idea of expected value. The expected value of an event is the average value we would expect to see if the event were repeated many times.

In this case, the expected value of the number of times the spinner will land on yellow in 72 spins is simply the probability of landing on yellow multiplied by the number of spins:

Expected value = Probability of yellow x Number of spins

Expected value = (1/6) x 72

Expected value = 12

Therefore, the best prediction possible for the number of times the spinner will land on yellow if it is spun 72 times is 12. This means that out of 72 spins, we can expect the spinner to land on yellow approximately 12 times on average. However, it's important to remember that this is just a prediction based on probability, and the actual number of yellow spins may vary.

Answer:

\(b_0 = 16.471\)

Step-by-step explanation:

Given

\(\begin{array}{ccccc}x & {15} & {12} & {10} & {7} \ \\ y & {5} & {7} & {9} & {11} \ \end{array}\)

Required

The least square estimate \(b_0\)

Calculate the mean of x

\(\bar x = \frac{\sum x}{n}\)

\(\bar x = \frac{15+12+10+7}{4} =\frac{44}{4} = 11\)

Calculate the mean of y

\(\bar y = \frac{\sum y}{n}\)

\(\bar y = \frac{5+7+9+11}{4} =\frac{32}{4} = 8\)

Calculate \(\sum(x - \bar x) * (y - \bar y)\)

\(\sum(x - \bar x) = (15 - 11) * (5 - 8)+ (12 - 11) * (7 - 8) + (10 - 11) * (9 - 8)+ (7 - 11) * (11 - 8)\)

\(\sum(x - \bar x) = -26\)

Calculate \(\sum(x - \bar x)^2\)

\(\sum(x - \bar x)^2 = (15 - 11)^2 + (12 - 11)^2 + (10 - 11)^2 + (7 - 11)^2\)

\(\sum(x - \bar x)^2 = 34\)

So:

\(b = \frac{\sum(x - \bar x) * (y - \bar y)}{\sum(x - \bar x)^2}\)

\(b = \frac{-26}{34}\)

\(b_0 = y - bx\)

\(b_0 = 5 - \frac{-26}{34}*15\)

\(b_0 = 5 + \frac{26*15}{34}\)

\(b_0 = 5 + \frac{390}{34}\)

Take LCM

\(b_0 = \frac{34*5+ 390}{34}\)

\(b_0 = \frac{560}{34}\)

\(b_0 = 16.471\)

The book has a lower cost per minute than the movie.

To find the cost per minute of the book, we divide the cost by the number of minutes:

cost per minute of book = $15 / 200 minutes = $0.075 per minute

To find the cost per minute of the movie, we need to convert the time to minutes.

2 hours and 39 minutes is equal to:

2 hours x 60 minutes/hour = 120 minutes

39 minutes = 39 minutes

Total minutes = 120 + 39 = 159 minutes

cost per minute of movie = $14 / 159 minutes = $0.088 per minute

Therefore, the book has a lower cost per minute than the movie.

The rate of interest is 73%.

What is the annual rate?

The term annual percentage rate of charge refers to the interest rate for an entire year rather than just a monthly fee or rate as applied on a loan, mortgage loan, credit card, etc. It can also be referred to as a nominal APR or an effective APR. It is an annual rate of a finance charge.

Given that 1 dollar to grow to X dollars in 2 years is given by the formula X = (1+r) ².

A dollar to triple in 2 years.

Thus putting X = 3 in X = (1+r) ²

3 = (1+r) ²

Take square root on both sides:

√3 = 1 + r

Subtract 1 from both sides:

r = √3 - 1

Answer:

12 inches

Step-by-step explanation:

Given

\(\theta = 31^{\circ}\)

\(diagonal = 23.3\ in\)

Required

Determine the height of the canvas

The question is illustrated using the attached image.

Using the attachment as a point of reference, the height is calculated from

\(sin \theta = \frac{opp}{hyp}\)

This gives:

\(sin 31^{\circ}= \frac{h}{23.3}\)

Make h the subject

\(h = 23.3 * sin(31^{\circ)\)

\(h = 23.3 * 0.5150\\\)

\(h = 11.9995\)

\(h = 12\ inches\)

Answer:

To multiply a mixed number by a whole number, you can first convert the mixed number to an improper fraction and then multiply it by the whole number. Here are the steps to solve 3 1/5 x 10:

Convert 3 1/5 to an improper fraction:

3 1/5 = (3 x 5 + 1) / 5 = 16/5

Multiply the improper fraction by 10:

16/5 x 10 = (16 x 10) / 5 = 160/5

Simplify the result if possible:

160/5 = 32

Therefore, 3 1/5 x 10 = 32.

Answer:

We can use the formula for compound interest to solve this problem. The formula is:

A = P * (1 + r/n)^(n*t)

where:

A = the amount of money after t years

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $5000, r = 0.03, n = 12 (since the interest is compounded monthly), and t = 10. Plugging these values into the formula, we get:

A = 5000 * (1 + 0.03/12)^(12*10)

A = 5000 * (1.0025)^120

A ≈ $6,621.36

So the investment will be worth approximately $6,621.36 after 10 years.

Answer:

\(\frac{a^{m} }{a^{n} }\) = \(a^{m-n}\)

then

\(\frac{3^{\frac{4}{9} } }{3^{\frac{2}{9} } }\)

= \(3^{\frac{2}{9} }\) ← third expression

We have 3 line equations.

To check if the lines are parallel, perpendicular or neither, we need to check their slopes. If the slopes are equal, the lines are parallel, if the slope of one of the lines is equal to minus the inverse of the other slope, the lines are perpendicular, and finally, if any of those statements is not fullfilled, they are neither.

To find the slope of each line equation, let's rewrite all of them in slope-intercept form.

The slope-intercept form is

Where m represents the slope and b the y-intercept.

Now, let's rewrite our equations.

For the first line we have:

For the second we have:

And finally, for the third:

Our lines in slope intercept form are:

The slopes are, respectively

Since

We have

2x - 8y = -24 and x - 4y = 4 are parallel;

2x - 8y = -24 and 4x + y = -2 are perpendicular;

x - 4y = 4 and 4x + y = -2 are perpendicular.
