By determining the proportion of classmates who prefer green and applying it to the entire school population, we predict that approximately 72 students at the school would choose green as their favorite color.

To predict the number of students who favor green as their favorite color, we will assume the sample of classmates is representative of the entire school.

First, we need to find out how many students in the class chose green as their favorite color. Say, for example, 4 of the 22 classmates picked green. To find the predicted number for the school, we calculate:

Number of green-favoring classmates / Total classmates = Proportion of green-favoring classmates

4 / 22 = 0.1818 (rounded to four decimal places).

Now, apply this proportion to the entire school population:

0.1818 × 396 = Predicted number of students who favor green at the school.

71.55 - Since we can't have a fraction of a student, we round to the nearest whole number, predicting that about 72 students in the school would choose green as their favorite color.

Based on the data provided, I predict that approximately 72 students in the school would choose green as their favorite color.

1. Since you surveyed 22 classmates, the percentage of classmates who prefer green can be calculated. Let's assume that [tex]\( x \)[/tex] represents the number of classmates who prefer green. Therefore, [tex]\( \frac{x}{22} \)[/tex] is the proportion of classmates who prefer green.

2. Now, we can use this proportion to estimate the total number of students in the school who prefer green. Since there are 396 students in total, the estimated number of students who prefer green would be[tex]\( \frac{x}{22} \times 396 \).[/tex]

Now, let's find [tex]\( x \):[/tex]

- Let's assume [tex]\( y \)[/tex] is the number of classmates who prefer green. Since you surveyed 22 classmates, the percentage of classmates who prefer green can be calculated as [tex]\( \frac{y}{22} \).[/tex]

- Assuming that the number of classmates who prefer green is proportional to the total number of students who prefer green in the school, we can set up a proportion: [tex]\( \frac{y}{22} = \frac{x}{396} \).[/tex]

- Cross-multiplying, we get [tex]\( 396y = 22x \).[/tex]

- Solving for [tex]\( x \),[/tex] we find [tex]\( x = \frac{396y}{22} \).[/tex]

- Since we don't know the exact number of classmates who prefer green, let's assume a hypothetical scenario where 4 of your classmates prefer green. So, [tex]\( y = 4 \).[/tex]

- Substituting [tex]\( y = 4 \)[/tex] into the equation, we get [tex]\( x = \frac{396 \times 4}{22} = \frac{1584}{22} = 72 \).[/tex]

By surveying your classmates, you get a sample proportion of those who prefer green. Extrapolating this proportion to the entire school population, you can estimate the total number of students who prefer green. However, this estimation assumes that your classmates' preferences are representative of the entire school's preferences. So, based on this calculation, approximately 72 students in the school are predicted to choose green as their favorite color.

Answer:

w = 4 m

Step-by-step explanation:

The volume (V) of a cuboid is

V = lwh ( l is length, w is width and h is height )

Given V = 144 m³, then

lwh = 144 ( substitute l = 3 and h = 12 )

3 × w × 12 = 144

36w = 144 ( divide both sides by 36 )

w = 4

The volume of a rectangular prism is given by the product of its dimension: let w, h, l be the width, height and length of the prism, we have

[tex]V = whl[/tex]

In your case, everything is given except the width:

[tex]144 = w\cdot 3 \cdot 12 \iff 144 = 36w \iff w = \dfrac{144}{36} = 4[/tex]

Answer:

p > 5 and p <-8

Step-by-step explanation:

To solve this, you first need to isolate p.

First add 6 on both sides of the equation:

[tex]-6 + |2p+3| >7\\\\(+6) -6 + |2p+3| >7 +6\\\\2p + 3 > 13[/tex]

Then subtract 3 from both sides of the equation.

[tex]2p+3-3>13-3\\\\2p > 10\\[/tex]

The divide both sides by 2.

[tex]\dfrac{2p}{2}>\dfrac{10}{2}\\\\p>5[/tex]

Another solution is possible because of the absolute value.

If [tex]|2p+3|>13[/tex]

Then [tex]|2p+3|<-13[/tex]

Thus we can solve the second solution:

[tex]|2p+3|<-13[/tex]

[tex]2p+3<-13[/tex]

Isolate P again by subtracting both sides by 3

[tex]2p+3-3<-13-3[/tex]

[tex]2p<-16[/tex]

Then divide both sides by 2:

[tex]\dfrac{2p}{2}<-\dfrac{16}{2}[/tex]

[tex]p<-8[/tex]

Answer:

p > 5, p < -8

Step-by-step explanation:

We are given the following inequality and we are to find its solution:

[tex]-6+|2p+3|>7[/tex]

Adding 6 to both sides to get:

[tex]-6+6+|2p+3|>7+6[/tex]

[tex]|2p+3|>13[/tex]

We know the absolute rule that [tex]\mathrm{If}\:|u|\:>\:a,\:a>0\:\mathrm{then}\:u\:<\:-a\:\quad \mathrm{or}\quad \:u\:>\:a[/tex].

So [tex]2p+3>13[/tex] or [tex]2p+3<-13[/tex]

[tex] 2 p > 1 3 - 3 [/tex], [tex] 2 p < - 1 3 - 3 [/tex]

[tex] 2 p > 1 0 [/tex], [tex] 2 p < - 1 6 [/tex]

Given expression

2(x + 3) + 5

In order to solve the expressions or to simplify the expressions, basic mathematical rules are considered.

Basic mathematical rules include the BODMAS. The order is Brackets, of powers, division, multiplication, addition and then subtraction is solved at last.

For the given expression, the 2 outside the bracket (x+3) will be multiplied inside first.

=> 2(x+3) + 5

Step 1:

=> 2x + 2(3) + 5

Step 2:

=> 2x + 6 + 5

Step 3

=> 2x+11

So the first step is 2x + 2(3) + 5 ..

Answer:

2x + 2(3) + 5

Step-by-step explanation:

For this system of equation I used substitution:

Step 1: Every time you see a y in the equation y = 2x - 1 replace it with -4x - 19

-4x - 19 = 2x - 1

Step 2: Isolate x

(-4x + 4x) - 19 = (2x + 4x) - 1

-19 = 6x - 1

-19 + 1 = 6x + (- 1 + 1)

-18 = 6x

x = -3

Step 3: To solve for y replace x in the equation y = 2x - 1 with -3

y = 2(-3) - 1

y = -6 - 1

y = -7

(-3, -7)

Check:

-7 = -4(-3) - 19

-7 = 12 - 19

-7 = -7 --------------------------------> Correct!

-7 = 2(-3) - 1

-7 = -6 - 1

-7 = -7 --------------------------------> Correct!

The formula of an area of a circle:

[tex]A=\pi r^2[/tex]

r - radius

The ratio of the areas of the difference circles:

[tex]\dfrac{A_1}{A_2}=\dfrac{\pi r_1^2}{\pi r_2^2}=\dfrac{r_1^2}{r_2^2}=\left(\dfrac{r_1}{r_2}\right)^2[/tex]

We have

Circle A: r₁ = 4ft

Circle B: r₂ = 9 ft

Substitute:

[tex]\dfrac{A_A}{A_B}=\left(\dfrac{4}{9}\right)^2=\dfrac{16}{81}[/tex]

the ratio of the area of Circle A to the area of Circle B is 16/81, which corresponds to answer choice (d).

To find the ratio of the area of Circle A to the area of Circle B, we use the formula for the area of a circle, which is A = (pi)r^2. For Circle A, with a radius of 4 feet, the area is (pi)(4 ft)^2. For Circle B, with a radius of 9 feet, the area is (pi)(9 ft)^2.

Calculating these areas:

Area of Circle A = (pi)(4 ft)^2 = 16(pi) ft^2

Area of Circle B = (pi)(9 ft)^2 = 81(pi) ft^2

Now, we take the ratio of the two areas:

Ratio = (Area of Circle A) / (Area of Circle B) = (16(pi) ft^2) / (81(pi) ft^2) = 16/81

Therefore, the ratio of the area of Circle A to the area of Circle B is 16/81, which corresponds to answer choice (d).

log 64

Step-by-step explanation:

Using the rules of logarithms

• log [tex]x^{n}[/tex] ⇔ nlogx

• logx + logy ⇔ log xy

Given

2 log 4 + log 2 + log 2

= log 4² + log (2 × 2)

= log 16 + log 4

= log (16 × 4) = log 64

Answer:

A, log 64

Step-by-step explanation:

your answer A, log 64 is correct. i will explain why below:

2 log 4, log 2 and log 2 have the same bases (10), meaning they are able to be added easier. but before we add, we use the Power Rule of Logarithms on 2 log 4

the Power Rule says that we can move an exponent in a logarithm to the front then solve. this also applies to the reverse, as we can move 2 back as an exponent of 4 and solve

2 log 4 ---> log 4² < simplify the exponent and we get log 16

we can now use the Product Rule of Logarithms where log x + log y = log(xy)

we can use that on the first two terms of the addition

log 16 + log 2 ----> log (16 × 2) = log 32

now we can apply the other log 2 to the rule but instead with log 32

log 32 + log 2 ---> log (32 × 2) = log 64

our answer is log 64

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

We have y-intercept b = -2. Substitute:

We have the point (4, 12) → x = 4, y = 12. Put them in the equation:

12 = 4m - 2         add 2 to both sides

14 = 4m       divide both sides by 4

14/4 = m → m = 3.5

Answer:

y = 3.5x - 2

Step-by-step explanation:

We know that the y-intercept of our equation is -2, so our current equation is: y = mx - 2. Now we have to find m, which is the slope. Now, we plug in the points into the equation y = mx - 2, and we get 12 = 4m - 2. Thus, m is 3.5. Our final equation is y = 3.5x - 2.

The probability that we will get a lead role, given that we are chosen to be in the play is 0.5.

Probability is the ratio that shows the likelihood of an event occurring from a given set of possible events.

The probability that we will be chosen for the play is 0.4.

The probability that we will get the lead role is 0.1.

We have to find the probability that we get a lead role, given that we are already chosen to be in the play.

In this situation, the probability can be found by adding the probability of being chosen and the probability that we will get the lead role.

This can be done as shown below:

The probability that we get a lead role, given that we are already chosen to be in the play = The probability that we will be chosen for the play + The probability that we will get the lead role

= 0.4 + 0.1
