Answer:

Hello! answer: 13

Step-by-step explanation:

12 × 12 = 144

5 × 5 = 25

144 + 25 = 169

√169 = 13

13 × 13 = 169 therefore the length of the missing side is 13 hope that helps!

Answer:

0.04

Step-by-step explanation:

For a density curve, total area = 1

Probability lies in between 0 and 1

The Area of triangle :

Area = 1/2 base * height

Base = 0 - 50 = 50

Area = 1

Hence,

1 = 1/2 * 50 * h

1 = 50h / 2

2 = 50h

h = 2 / 50

h = 0.04

Answer:

Last answer is correct..

Answer:

The family has 1/4 of the strawberries left to snack on, or 31 left to snack on.

Step-by-step explanation:

Since they gave away 1/4 of the strawberries to their neighbor, and the others were used in a pie, that means that 1/4 of the strawberries remain. You do 124/4 in which 1/4 of that is 31, since 31x4 is equal to 124.

Answer:

  center: (1/2, 6)

  radius: √5

Step-by-step explanation:

The standard form equation for a circle of radius r and center (h, k) is ...

  (x -h)^2 +(y -k)^2 = r^2

When we compare this to the given equation:

  (x -1/2)^2 +(y -6)^2 = 5

we see that h=1/2, k=6, and r^2=5.

The center is (h, k) = (1/2, 6); the radius is √5.

Answer:

The 95% confidence interval is [tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

A random sample of 432 voters revealed that 100 are in favor of a certain bond issue.

This means that [tex]n = 432, \pi = \frac{100}{432} = 0.231[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

Confidence interval:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]

The 95% confidence interval is [tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]

Answer:

x = 2

Step-by-step explanation:

Let the number be x

When we multiply a number by 6 and subtract it by 5, we would get 7.

On multiplication of number x with 6 it will be 6x.12

On subtraction of 5 it will be 6x - 5

6x - 5 = 7

6x = 7 + 5  

6x = 12

x = 12/6

x = 2

Answer:

The number is 2

Step-by-step explanation:

Let the number be n

Multiply the number by 6 = 6n

Subtract 5 from the number , 6n - 5

And we get 7

So , the expression : 6n - 5 = 7

                                6n = 7 + 5

                                6n = 12

                                  n = 2

Answer:

a. The minimum sample size required is of 60,025.

b. The minimum sample size required is of 20,465.

c. The minimum sample size required is 9,589.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

Question a:

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

p and q unknown means that we use [tex]\pi = 0.5[/tex], which is when the largest sample size is needed.

Margin of error: 0.004

We have to find n for which M = 0.004. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.004 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.004\sqrt{n} = 1.96*0.5[/tex]

[tex]\sqrt{n} = \frac{1.96*0.5}{0.004}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.004})^2[/tex]

[tex]n = 60025[/tex]

The minimum sample size required is of 60,025.

b. Margin of error: 0.009, confidence level: 99%; p and q unknown

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

Margin of error: 0.009

We have to find n for which M = 0.009. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.009 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.009\sqrt{n} = 2.575*0.5[/tex]

[tex]\sqrt{n} = \frac{2.575*0.5}{0.009}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.009})^2[/tex]

[tex]n = 20464.9[/tex]

Rounding up:

The minimum sample size required is of 20,465.

c. Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%.

Here we have [tex]\pi = 0.52[/tex].

The minimum sample size is n for which M = 0.01. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.01 = 1.96\sqrt{\frac{0.52*0.48}{n}}[/tex]

[tex]0.01\sqrt{n} = 1.96\sqrt{0.52*0.48}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.52*0.48}}{0.01}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.52*0.48}}{0.01})^2[/tex]

[tex]n = 9588.6[/tex]

Rounding up:

The minimum sample size required is 9,589.

Step-by-step explanation:

"-+_$-5_(#-3(

Answer:

x = 4

Step-by-step explanation:

2x + 6 = 7x - 14

2x + 6 - 2x + 14 = 7x - 14 - 2x + 14 ----> To put the variables on one side and the numbers on the other side

20 = 5x --> Simplifying

x = 20/5 --> Flipping the equation and then dividing 5 on both sides

x = 4 --> Simplifying

Answer: 240 feet

Step-by-step explanation:

What you could do is find the area of the whole thing. 12x25 is 300. Then, you can find the area of the white part, which is 60, because you multiply 12x5. then, you would subtract 60 to 300, which would get you to 240 feet.

Answer:

The answer is : 240cm² for the shaded part

The unshaded part is = 60cm²

The whole rectangle = 300cm²

Step-by-step explanation:

Area is = WL

W = width (while the) L= length

The Area = 25 × 12 = 300

The area of the full rectangle is = 300

The unshaded part is = 5 × 12 = 60

So the shaded part is = 300 - 60 = 240cm²

[tex]so \: the \: answer \: is \: = 240cm^{2} [/tex]

Answer:

  B.  66°

Step-by-step explanation:

The remote exterior angle (z) is the sum of the measures of the interior angles (x, y).

  x + y = z

  (5n -19) +(n +7) = (144 -6n)

  12n = 156 . . . . . . . . . . . . . . . . . add 6n+12

  n = 13 . . . . . . . . . . . . . . divide by 12

Then the measure of the remote exterior angle is ...

  m∠z = (144 -6(13))° = (144 -78)°

  m∠z = 66°

__

x = 46°

y = 20°

Answer:

[tex]volume \: of \: the \: rectriangular \: prism = ( \frac{1}{2} \times base \times 4) \times 2 \\ 4 \times base = 40 \\ base = 10m[/tex]

Answer:

length = 15 meters

Step-by-step explanation:

Volume of a pyramid is:

V = l*w (h/3)

We know that; Volume is 40, Width is 2, and Height is 4, therefore;

40 = l*2 (4/3)

40 = 2l (4/3)

(3/4) * 40 = 2L

30 = 2L

30/2 = L

15 = L

therefore the length = 15 meters
