Answer: A is the answer

Step-by-step explanation:

Answer: 0.5

Step-by-step explanation:

To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.

Fraction: 7/10 already reduced to the lowest terms.

The numerator and denominator have no common prime factors.

Their prime factorization:

7 is a prime number;

10 = 2 × 5;

gcf (7; 2 × 5) = 1;

Answer:

First you have to find the common denominator

Next you take what you did to the bottom you gotta do to the top like if you 30 does into both them you multiple 3 times 2 cause you did that to 15 and multiply 7 times 3

Then you subtract

Complete question is;

Elle Measured the height of a plant, in inches,Every week for four weeks after planting it.

The height of the plant, h, in inches, Can be modeled by the function h(t) = 1.5t + 3, where t represents the time in weeks.

Based on this model, what is the best prediction for the height of the plant after 12 weeks?

A 16.5 inches

B 21 inches

C 22.5 inches

D 27.3 inches

Answer:

Option B: 21 inches

Step-by-step explanation:

We are given the function h(t) = 1.5t + 3, where t represents the time in weeks.

At t = 0;

h(0): 1.5(0) + 3 = 3inches

At t = 1;

h(1): 1.5(1) + 3 = 4.5 inches

Thus, after 12 weeks, height will be;

h(12): 1.5(12) + 3 = 21 inches

Option B is correct

Answer:

1. Couples tickets: $8

   Individual tickets: $4

2. Song download cost: $2

    Movie download cost: $15

Step-by-step explanation:

You can solve both of these questions by doing system of equations.

Let's start with question 1.

There are 2 variables in this equation:

- Couples tickets price: let's represent these with the letter C

- Individual tickets price: let's represent these with the letter K

Writing the two equations would look this these:

5c + 2k = 48

3c + 2k = 32

Next, isolate a variable. I am going to isolate K in the first equation.

[tex]2k = -5c + 48 \\k = -\frac{5}{2}c + 24[/tex]

Now that we isolated a variable we can plug that back in to the second equation:

[tex]3c + 2(-\frac{5}{2}c + 24) = 32\\3c - \frac{10}{2}c + 48 = 32\\3c -5c + 48 = 32\\-2c + 48 = 32\\-2c = -16\\c = 8[/tex]

We found that c is equal to 8 so we can put that back in to an equation to solve for k.

5(8) + 2k = 48

40 + 2k = 48

2k = 8

k = 4

Therefore, the price for couples tickets is $8 and the price for individual tickets is $4.

Check #1:

5(8) + 2(4) = 48

40 + 8 = 48

48 = 48

3(8) + 2(4) = 32

24 + 8 = 32

32 + 32

Now, let's go on to question 2.

There are 2 variables in this equation:

- Price of songs downloaded: let's represent these with S

- Price of movies downloaded: let's represent these with M

Writing the two equations would look like this:

15s + 11m = 195

15s + 8m = 150

There is a simple way to answer this system, however.

If you change the bottom equations signs to negative you can minus the second equation from the first equation like this:

15s + 11m = 195

-(15s +8m = 150)

Minus them to get this equation:

3m = 45

Solve

m = 15

We have found that each movie download costs $15, now let's plug this back into an equation:

15s + 11(15) = 195

15s + 165 = 195

15s = 30

s = 2

Each song costs $2 to download.

Check #2:

15(2) + 11(15) = 195

30 + 165 = 195

195 = 195

15(2) + 8(15) = 150

30 + 120 = 150

150 = 150

I hope this helps!!

Answer:

*correct me if I'm wrong with the equation setup but I believe this is your answer.*

( 6 × n ) - 5 = 13

( 6 x n ) = 18

n = 3

The step that is not allowed is (b) add the left side of equation 2 to the left side of equation 1

The system of equations is given as:

2x - 3y = 12

-2x + y = 8

This means that the step that is not allowed is (b)

Step-by-step explanation:

The line y = 1 has a slope of 0, and the line parallel to it, for instance, y = 3, has the same slope, m1 = 0. For the slope of the line perpendicular to that parallel line is m2 = -1/m1, which is -1/0 = ∞

Step-by-step explanation:

Following are the solution to the given points:

Assume A, P, and B is the masses of apples, pears, and basket, respectively.

[tex]\to W = 4A + 6P + B[/tex]

Calculating the mean of W:

[tex]\to \bold{W = E(W) }[/tex]

         [tex]\bold{= E(4A + 6P + B)} \\\\ \bold{= 4E(A) + 6E(P) + E(B)}\\\\\bold{= 4 \times 4.72 + 6 \times 5.41 + 13.52} \\\\ \bold{= 18.88 + 32.46 + 13.52} \\\\ \bold{= 64.86 }[/tex]

Calculating the variance of W:

[tex]\to \bold{W=Var(W)}\\\\[/tex]

         [tex]\bold{= Var(4A + 6P + B)}\\\\ \bold{= 42 Var(A) + 62 Var(P) + Var(B)}\\\\\bold{= 16 \times 0.22 + 36 \times 0.182 + 1.882}\\\\ \bold{= 3.52 + 6.552 + 1.882}\\\\ \bold{= 5.3408}[/tex]

Calculating the standard deviation of W:

[tex]\to \bold{W= \sqrt{5.3408}= 2.311017}[/tex]

The linear combination of Normal random variables is known to follow the normal distribution.

[tex]\to \bold{W \sim N(64.86 , 2.311017)}[/tex]

Calculating the Probability of the Total Weight is more difficult.[tex]\to \bold{67 = P(W > 67)}[/tex]  

         [tex]\bold{= P[ Z > \frac{(67 - 64.86)}{ 2.311017}]}\\\\\bold{= P[Z > 0.93]}\\\\\bold{= 0.1762}[/tex] (Using Standard Normal distribution)

Therefore, the final answer is "64.86, 2.311017, and 0.1762".

Answer:

It is a function

Step-by-step explanation:

A function is of the form:

[tex]\left[\begin{array}{c}x_1&x_2&x_3\\-&-&-\\x_n\end{array}\right][/tex]            [tex]\left[\begin{array}{c}y_1&y_2&y_3\\-&-&-\\y_n\end{array}\right][/tex]

Where each of the x values must be distinct.

The x values are referred to as domain while the y values are called range.

Having said that, the given data can be represented as follows:

[tex]\left[\begin{array}{c}-3&1&6\\7&12\end{array}\right][/tex] ----------- [tex]\left[\begin{array}{c}7&-8&-6\\-8&2\end{array}\right][/tex]

From the representation above, none of the x values are repeated.

Hence, it is a function

Answer:

47.1 cm

Step-by-step explanation:

The circumference of a circle is denoted by C = 2πr, where r is the radius.

Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:

C = 2πr

C = 2 * 3.14 * 7.5 = 47.1

To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.

Thus, the circumference is 47.1 cm.

Answer:

(0.131) , (0.044)

Step-by-step explanation:

Given:

Total sample n = 200

Yield x = 35

Confidence level = 90%

Find:

Proportion non-conforming

Computation:

Proportion p = x / n

Proportion p = 35 / 200 = 0.175

Non Proportion q = 1 - p

Non Proportion q = 0.825

So,

z value of 90% is 1.64

So,

Proportion non-conforming

p ± [z√pq/n]

0.175 ± [1.64√(0.175)(0.825)/200
