Rosalind made 969 donuts and put 8 donuts into each box. How many boxes of donuts were made

Answers

Answer 1

Answer:

121 donuts in each box

Step-by-step explanation:

969 divided by 8 = 121.125

(Ignore the remainder)

Answer 2

Step by step solution:

We know that there are 969 doughnuts, and there are 8 doughnuts per box. What we need to find out is how many boxes of doughnuts were made.

Step 1:

Set up an equation for Number of doughnuts (969) / Number of doughnuts per box (8) = Number of boxes made (x), which would look like this:

969/8 = x

Step 2:

Doing this, we can get 121.125, which leaves us with

121.125 = x

121.125 = 121.125

Which gives us the answer of 121.125, which we can shorten to 121, as the decimal is not necessary.

Checking our answer:

We can check our answer simply be rewording our 1st equation to solve for the number of doughnuts made. This would give us the equation Number of doughnuts per box (8) * Number of boxes made (121.125) = x. Solving this equation would look like

8 * 121.125 = x

969 = x

969 = 969

Answer: By completing the steps above we get 121, and we can check our work by rewording the problem to solve for the number of Doughnuts. Good Luck!

Show your work for credit.

Answers

Answer:

(x - 1)² + (y - 1)² = 25

Step-by-step explanation:

Find the center, the midpoint of the diameter:

x = (4 - 2)/2 = 1, this is h of the circle equationy = (-3 + 5)/2 = 1, his is k of the circle equation

Find the square of the radius by distance formula:

r² = (1 - 4)² + (1 + 3)² = 25

Equation of the circle:

(x - h)² + (y - k)² = r²,

Substitute the values to get:

(x - 1)² + (y - 1)² = 25

Answer:

solution given:

points at (4, -3) and (-2, 5

diameter [d]=

[tex]d = \sqrt{(4 + 2) {}^{2} +( - 3 - 5) {}^{2} } \\ d = 10units \\ radius(r) = 5units [/tex]

centre[h,k]={(4-2)/2,(-3+5)/2}=(1,1)

now equation of a circle

(x-h)²+(y-k)²=r²

(x-1)²+(y-1)²=25 is a required equation

4. The volume of a certain room is 2016 cubic ft. If the square footage of the
floor is 144 sq. ft., what will the height of the room be?

Answers

Answer:

The room is 14ft high

Step-by-step explanation:

Given

[tex]Volume = 2016ft^3[/tex]

[tex]Base\ Area = 144ft^2[/tex]

Required

The height of the room

This is calculated as:

[tex]Volume = Base\ Area * Height[/tex]

Make Height the subject

[tex]Height = \frac{Volume}{Base\ Area}[/tex]

So, we have:

[tex]Height = \frac{2016ft^3}{144ft^2}[/tex]

[tex]Height = \frac{2016}{144}ft[/tex]

[tex]Height = 14ft[/tex]

Find the f^-1(x) and it’s domain

Answers

Answer:

[tex]f^{-1}(x) = (x + 8)^2[/tex]

[tex]x \ge -8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \sqrt x - 8[/tex]

Solving (a): [tex]f^{-1}(x)[/tex]

We have:

[tex]f(x) = \sqrt x - 8[/tex]

Express f(x) as y

[tex]y = \sqrt x - 8[/tex]

Swap x and y

[tex]x = \sqrt y - 8[/tex]

Add 8 to [tex]both\ sides[/tex]

[tex]x + 8 = \sqrt y - 8 + 8[/tex]

[tex]x + 8 = \sqrt y[/tex]

Square both sides

[tex](x + 8)^2 = y[/tex]

Rewrite as:

[tex]y = (x + 8)^2[/tex]

Express y as: [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x) = (x + 8)^2[/tex]

To determine the domain, we have:

The original function is [tex]f(x) = \sqrt x - 8[/tex]

The range of this is: [tex]f(x) \ge -8[/tex]

The [tex]domain[/tex] of the [tex]inverse[/tex] function is the [tex]range[/tex] of the [tex]original[/tex] function.

Hence, the domain is:

[tex]x \ge -8[/tex]

A psychologist has designed a questionnaire to measure individuals' aggressiveness. Suppose that the scores on the questionnaire are normally distributed with a standard deviation of 80. Suppose also that exactly 15% of the scores exceed 700. Find the mean of the distribution of scores. Carry your intermediate computations to at least four decimal places. Round your answer to at least one decimal place.

Answers

Answer:

The mean score is of 617.4.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Suppose that the scores on the questionnaire are normally distributed with a standard deviation of 80.

This means that [tex]\sigma = 80[/tex]

Suppose also that exactly 15% of the scores exceed 700.

This means that when X = 700, Z has a pvalue of 0.85. So X when X = 700, Z = 1.033. We use this to find [tex]\mu[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.033 = \frac{700 - \mu}{80}[/tex]

[tex]700 - \mu = 80*1.033[/tex]

[tex]\mu = 700 - 80*1.033[/tex]

[tex]\mu = 617.4[/tex]

The mean score is of 617.4.

Part A: To find the volume of a cylinder, we need the dimensions of the cylinder such as the radius of the base of the cylinder and the height of the cylinder.

Part B: We have given the base of the refraction cup as a half-circle, we can calculate the radius of the base.

The diameter is given as 8 cm so, the radius would be half of the diameter.

r = 4cm

Part C:  If you put two refraction cups together, we get the full three-dimensional shape that is a circle.

Part D: The formula for the volume of a cylinder is V=pi r^2 h.

Part E: The volume of a refraction cup =

= 4/3 (3.14)(8)

= 33.49

Part F: The relationship between the value D and the value from Part D is as follows
