Natalie made blueberry muffins for a bake sale. Each muffin cost her about $0.25 to make. She spent $8.75 to make all of the muffins. Natalie sold each muffin for $0.50 more than it cost her to make.

What is the total amount of money that Natalie received from selling her muffins?

Answer:

We will first find out average time of each student.

Student 1 = 60 / 12 = 5

Student 2 = 60 / 10 = 6

Student 3 = 60 / 8 = 7.5

Student 4 = 60 / 6 = 10

Student 5 = 60 / 4 = 15

Now we will take the arithmatic mean of all students average time.

A = (5+6+7.5+10+15)/5 = 43.5/5 = 8.7 minutes per problem

Do you need to create an algebraic expression? In that case, the answer would be 6x.

Answer:

False

Step-by-step explanation:

Answer:

95% of all students at private universities pay less than $58,302.5.

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.

Mean of $50,900, standard deviation of $4,500

This means that [tex]\mu = 50900, \sigma = 4500[/tex]

Ninety-five percent of all students at private universities pay less than what amount?

Pay less than the 95th percentile, and the amount is given by X when Z has a pvalue of 0.95, so X when Z = 1.645.

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

[tex]1.645 = \frac{X - 50900}{4500}[/tex]

[tex]X - 50900 = 1.645*4500[/tex]

[tex]X = 58302.5[/tex]

95% of all students at private universities pay less than $58,302.5.

The question supplied is incomplete :

The x parameters aren't given ; "Units with weights less than or greater than ounces will be classified as defects"

Assume the unit weights Given are ;

Units with weights less than 10.8 or greater than 11.2 ounces will be classified as defects

Just follow the procedure in the solution for any value of unit weight interval given.

Answer:

0.3173

Step-by-step explanation:

Mean weight, m = 11 ounces

Standard deviation, s = 0.2 ounces

Find the Zscore for each unit weight :

Z = (x - mean) / standard deviation

P(x < 10.8) :

Z = (10.8 - 11) / 0.2 = - 1

P(Z < - 1) = 0.15866

P(x > 11.2) :

Z = (11.2 - 11) / 0.2 = 1

P(Z > 1) = 0.84134

P(x < 11.2) - P(x < 10.8) = 1 - (P(Z < 1) - P(Z < - 1)) = 1 - 1 - (0.84134 - 0.15866) = 1 - 0.68268 = 0.31732

Hence, Probability of a defect is 0.3173

Hi there!

[tex]\large\boxed{8(5+3)}}[/tex]

The greatest common factor of 40 and 24 is 8.

8 goes into 40 5 times:

8 goes into 24 3 times.

We can rewrite this expression for distribution using the amount of times 8 goes into both numbers:

8(5 + 3)

Using this, we get:

8(5) + 8(3) = 40 + 24.

Answer: The mean is the same as the average. In order to find the mean, or average score of the two tests, you need to take the sum of the two tests, and then divide by the number of tests, which is two.

We don't know the score of the second exam. Let it = x

Then we have the following equation:

(88 + x)/2 = 93

88 + x = 2 * 93

88 + x = 186

x = 186 - 88 = 98

You need to score a 98 on the second test

Answer:

The sine function is:

[tex]y(x)=\frac{2}{3}sin[3\pi (x-\frac{2\pi}{3})]-2[/tex]

Step-by-step explanation:

We need to recall that a sine function can write as:

[tex]y(x)=Asin[B(x+C)]+D[/tex]

Where:

So we just need to use the listed attributes

Therefore, the sine function is:

[tex]y(x)=\frac{2}{3}sin[3\pi (x-\frac{2\pi}{3})]-2[/tex]

Answer:

the probability the emergency cooling system will work when needed is 80.5%

Step-by-step explanation:

 Given the data in the question;

the probability that someone will actually push the emergency button in an emergency from 90% to 99% of the time

E[tex]_4[/tex] ⇒ Someone will actually push the emergency button in an emergency

P(E[tex]_4[/tex]) = 90% = 0.90

E[tex]_4[/tex] : Someone will actually push the emergency button in an emergency

P(E[tex]_4[/tex]) = 99% = 0.99

P(E) = P(E1) × P(E2) × P(E3) × P(E4) × P(E5)

we substitute

P(E) = 92% × 94% × 96%  99% × 98%  

P(E) = 0.8054

P(E) = 80.5%

Therefore, the probability the emergency cooling system will work when needed is 80.5%

Answer:

616 cm²

Step-by-step explanation:

small cube (4 sides) = 8 x 3 x 4 = 96

large cube (4 sides) = 7 x 10 x 4 = 280

top and bottom of large cube = 12 x 10 x 2 = 240

(we would deduct the 3 x 3 area from  the top of the large cube and add a 3 x 3 area for the top of the small cube. So that cancels each other out.)

total surface area = 96 + 280 + 240 = 616 cm²

Answer:

1.5 thats the answer

Step-by-step explanation:

1.5

well, to do this we first need to find the mean of all values.

we need to find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)

Then find the mean of those distances.

so, after we do all of that with the given numbers, our final result would be 2.333333333..... (It goes on) we round it up to 2.3, and viola! the answer is C.

Answer:

a(t)=1350(1.9)t this is

Answer:

Step-by-step explanation:

Remark

The rate is going to be the same as the distance travelled in 1 hour. The units will be different.

Formula

d = r * t

Givens

d = 558 miles

t = 3 hours

Problem A

r = d / t

r = 558/ 3 = 186 miles / hr

Problem B

Givens

r = 186 miles / hour

t = 1 hour

d = ?

Solution

d = 186 mi/hr * 1 hr

d = 186 miles

Note

This looks really trivial, but it's not. You have to learn to see the difference between a number and its units. It's not very often that the numbers will be the same, but if the units differ, then it is an entirely different question.

Answer:

Step-by-step explanation:

Since the graph is moving down the slope has to be negative we need to write the answer in rise over run rise as in the y range and run as in x range

Answer:

17 x + 7 y = 20

y =20x - 42

17 x + 7(20x - 42) = 20

17x + 140x - 294 = 20

157 x = 20 + 294

157x ÷ 157 = 314 ÷ 157

x = 2

y = 20x - 42

y = 20 (2) - 42

y = 40 - 42

y = -2

there for x = 2 and y = -2 is the solution

Answer:

[tex](a)[/tex]

[tex]Maximum\ Error = 27[/tex]

[tex]Relative\ Error = 0.008[/tex]

[tex]Percentage\ Error = 0.8\%[/tex]

[tex](b)[/tex]

[tex]Maximum\ Error = 36[/tex]

[tex]Relative\ Error = 0.0267[/tex]

[tex]Percentage\ Error = 2.67\%[/tex]

Step-by-step explanation:

Given

[tex]x = 15[/tex] -- edge length

[tex]\triangle x = 0.2[/tex] -- possible error

Solving (a): Errors in volume

The volume of a cube is:

[tex]V(x) = x^3[/tex]

Differentiate

[tex]\frac{dV}{dx} = 3x^2[/tex]

Make dV the subject

[tex]dV =3x^2dx[/tex]

Rewrite as:

[tex]\triangle V = 3x^2 \triangle x[/tex]

Substitute values for x and [tex]\triangle x[/tex]

[tex]\triangle V = 3 * 15^2 * 0.2^2[/tex]

[tex]\triangle V = 27[/tex]

Hence:

[tex]Maximum\ Error = 27[/tex]

The relative error is then calculated as:

[tex]Relative\ Error = \frac{Maximum\ Error}{Volume}[/tex]

[tex]Relative\ Error = \frac{27}{x^3}[/tex]

[tex]Relative\ Error = \frac{27}{15^3}[/tex]

[tex]Relative\ Error = \frac{27}{3375}[/tex]

[tex]Relative\ Error = 0.008[/tex]

The percentage error is:

[tex]Percentage\ Error = Relative\ Error * 100\%[/tex]

[tex]Percentage\ Error = 0.008 * 100\%[/tex]

[tex]Percentage\ Error = 0.8\%[/tex]

Solving (a): Errors in Surface Area

The volume of a cube is:

[tex]A(x) =6x^2[/tex]

Differentiate

[tex]\frac{dA}{dx} =12x[/tex]

Make dA the subject

[tex]dA = 12xdx[/tex]

Rewrite as:

[tex]\triangle A =12x\triangle x[/tex]

Substitute values for x and [tex]\triangle x[/tex]

[tex]\triangle A =12 *15 * 0.2[/tex]

[tex]\triangle A =36[/tex]

Hence:

[tex]Maximum\ Error = 36[/tex]

The relative error is then calculated as:

[tex]Relative\ Error = \frac{Maximum\ Error}{Surface\ Area}[/tex]

[tex]Relative\ Error = \frac{36}{6x^2}[/tex]

[tex]Relative\ Error = \frac{36}{6*15^2}[/tex]

[tex]Relative\ Error = \frac{36}{1350}[/tex]

[tex]Relative\ Error = 0.0267[/tex]

The percentage error is:

[tex]Percentage\ Error = Relative\ Error * 100\%[/tex]

[tex]Percentage\ Error = 0.0267* 100\%[/tex]

[tex]Percentage\ Error = 2.67\%[/tex]
