Step-by-step explanation:

The answer is:

-0.5, -1.5

Answer:

First question: LCL = 522, UCL = 1000.5

Second question: A sample size no smaller than 418 is needed.

Step-by-step explanation:

First question:

Lower bound:

0.36 of 1450. So

0.36*1450 = 522

Upper bound:

0.69 of 1450. So

0.69*1450 = 1000.5

LCL = 522, UCL = 1000.5

Second question:

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 zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

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

The project manager believes that p will turn out to be approximately 0.11.

This means that [tex]\pi = 0.11[/tex]

95% confidence level

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

The project manager wants to estimate the proportion to within 0.03

This means that the sample size needed is given by n, and n is found when M = 0.03. So

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

[tex]0.03 = 1.96\sqrt{\frac{0.11*0.89}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.11*0.89}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.11*0.89}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.11*0.89}}{0.03})^2[/tex]

[tex]n = 417.9[/tex]

Rounding up

A sample size no smaller than 418 is needed.

Step-by-step explanation:

Answer:

y = 6

Step-by-step explanation:

-2y = 4x – 4

y = -2x + 2

7x = -4(-2x+2) + 10

7x = 8x-8+10

7x = 8x+2

7x -2 = 8x

-2 = x

plug this into the first equation and the value of y is 6

The value of y using substitution method on the given simultaneous equations is; y = -2

We are given the equations;

-2y = 4x - 4 - - -(eq 1)

7x = - 4y + 10 - - - (eq 2)

From eq 1, divide through by -2 to isolate y;

y = -2x + 2

Substitute -2x + 2 for y in eq 2 to get;

7x = -4( -2x + 2) +10

Expand the bracket to get;

7x = 8x - 8 + 10

7x = 8x + 2

8x - 7x = 2

x = 2

Put 2 for x in y = -2x + 2 to get;

y = - 2(2) + 2

y = -4 + 2

y = -2

Answer:

189/8 cm^3

Step-by-step explanation:

Given data

Base= 7/2 cm

Hieght= 3/2cm

Length= 9/2cm

We know that the expression for volume is

Volume = L*B*H

substitute our data

Volume= 7/2*3/2*9/2

Volume= 189/8 cm^3

Hence the volume is 189/8 cm^3

Answer:

Step-by-step explanation:

For the lateral area we have to find the perimeter:

p = 2 x 8 x π

p = 16 π

now we can find it

LA = p x height

LA = 16 π x 3 = 48 π

for find the the surface area we have to find the base area

Base area = radius^2 π

base area = 8^2 π = 64 π

now can we find it

SA = 2 x base area + LA

SA =  2 x 64π + 48π = 128π + 48π = 176π

V = base area x height

V = 64π x 3 = 192 π

Answer:

Answer:

r = 3 cm , LA= 30π cm^2 , SA = 48π cm^2

Step-by-step explanation:

This is a bit more difficult because we have to use the inverse formula

if

V = base area x height

we can obtain

base area = V/height

base area = 45π/5 = 9π cm^2

If

base area = radius^2 π

we can obtain

radius = √base area / π

r = √9 x π/π = 3 cm

base perimeter = 3 x 2 x π = 6π cm

LA = 6π x 5 = 30π cm^2

SA = 9π x 2 + 30 π = 48π cm^2

Answer:

7(6+9)

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

In a box-and-whisker plot, the whiskers show the minimum and maximum while the edges of the box show the first and third quartiles. The line in the box shows the median.

Quartile means a quarter of the data.

We're trying to find out what percentage of the students scored between 70 and 100.

70 is right on the 1st quartile mark, while 100 is on the maximum mark.

This means that a quarter of students got lower than 70, and nobody scored over 100 (because it's a test and it's calculated in percentage).

If a quarter of students got lower than 70, that means three-quarters of students got 70 or higher. And since the maximum is 100, and that is also what we're trying to find, the answer is 3/4 of all students.

3/4 = 75%

Hence, the answer is 75%.

Answer:

Area = 452.16 cm²

Volume = 904.32 cm³

Step-by-step explanation:

The solid is a sphere, therefore,

Volume = ⁴/3πr³

Where,

π = 3.14

r = 6 cm

Volume = ⁴/3*3.14*6³

Volume = 904.319997 ≈ 904.32 cm³ (nearest hundredth)

Area = 4πr²

Area = 4*3.14*6²

Area = 452.16 cm²

Answer:

x = 42

Step-by-step explanation:

Let the length of the indicated side be represented as "x".

The Theorem of proportionality can be extended and applied to find the indicated side.

Thus, based on the theorem, it is assumed that the parallel lines divides the transversals proportionally.

This implies that:

x/(77 - x) = 30/25

x/(77 - x) = 6/5

Cross multiply

x(5) = 6(77 - x)

5x = 462 - 6x

Add 6x to both sides

5x + 6x = 462

11x = 462

x = 462/11

x = 42

Answer:

P = I / rt is the formula we're going to use.

P is the principle (which is what we're solving for)

I = the interest accrued over the specified amount of time (2 years)

r = the interest rate (6%)

t = the time specified (2 years)

Change the percent to a decimal. Place the decimal two places to the left to make 0.06.

P = 264 / 0.06(2)

P = 264 ÷ 0.12 = 2,200

Principal borrowed would be $2,200
