Answer:

A is correct

Step-by-step explanation:

[tex]\frac{0.20}{1min}[/tex] = [tex]\frac{12.00\\}{1 hour}[/tex]  

We can scale the ratio to give the most accurate answer.

0.20 X 60 = 12.00

Answer:

Option A

Step-by-step explanation:

Here in this case the respondents differ from the non respondents in more than one ways and hence this results to a nonresponse bias due to which there is an extra thumbs up in support of firing the coach thereby leading to an over estimated number.

Hence, option A is correct

Answer: 45?

Step-by-step explanation: Sorry If I'm wrong, I haven't learned this yet but I tried my best.

Answer:

A sample size of 551 is required.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Population standard deviation of 7 hours.

This means that [tex]\sigma = 7[/tex]

Determine the sample size required to have a margin of error of 0.585 hours.

This is n for which M = 0.585. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.585 = 1.96\frac{7}{\sqrt{n}}[/tex]

[tex]0.585\sqrt{n} = 1.96*7[/tex]

[tex]\sqrt{n} = \frac{1.96*7}{0.585}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*7}{0.585})^2[/tex]

[tex]n = 550.04[/tex]

Rounding up(as for a sample of 550 the margir of error will be a bit above the desired target):

A sample size of 551 is required.

sinx=p/h -----> some people have

cosx=b/h ----> curly brown hair

tanx=p/b -----> through proper brushing

easy way to remember it

we need cos c for this

h= 26 which is always the longest side of the triangle

b= 10

p=24

these both can be switched depending on which angle the question is talking about in this case its angle C so 10 is the base, if it was angle a 24 would have been the base

[tex]cosC=\frac{10}{26} \\[/tex]

Answer:

Varies

Step-by-step explanation:

What this question is asking you to do is to measure the angle of the blue dot and find the 90 degree angle, so you need to get a protractor and measure the 90 degree angle in order to get the answer

Answer:

474.43 m²

Step-by-step explanation:

The shape is composed of a rectangle and a parallelogram

Area of the composite shape = area of the rectangle + area of the parallelogram

= Length*Width + base*height

Where,

Length = 20.9 m

Width = 14.3 m

base = 20.9 m

height = 22.7 - 14.3 = 8.4 m

Area = 20.9*14.3 + 20.9*8.4

Area = 298.87 + 175.56

= 474.43 m²

Answer:

1:15 P.M

Step-by-step explanation:

After 5 hours if will be 1:00 P.M and 25 minutes after it turns 1:00 P.M will be 1:15 P.M

Answer:

1 : 15p.m

Step-by-step explanation:

Answer:

base = 6.4 units or 6 2/5

Step-by-step explanation:

area = bh

24 = b(3.75)

b = 6.4 units or 6 2/5

Answer:

6.4

Step-by-step explanation:

Area = base x height

if height = 3.75 or 3 3/4

Divide

24 ÷ 3.75 = 6.4

base = 6.4

Answer:

$14.41

Step-by-step explanation:

set up a proportion then cross-multiply:

12.75 / 46 = x / 52

46x = 663

x = 14.41

Answer: The percentage of legal quarters will be rejected by the vending machine = 2.275%

Step-by-step explanation:

Given: The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram.

Let x be the weights of legal U.S. quarters .

Required probability: [tex]P(x<5.53)+P(x>5.81)[/tex]

[tex]=P(\dfrac{x-\mu}{\sigma}<\dfrac{5.33-5.67}{0.07})+P(\dfrac{x-\mu}{\sigma}>\dfrac{5.81-5.67}{0.07})\\\\=P(z<-4.857)+P(z>2)\approx0.02275 \ \ \ [By\ P-value\ calculator][/tex]

The percentage of legal quarters will be rejected by the vending machine = 2.275%

Answer:

a. IQR = 2.25

b. 40%

(I'm not sure about B.)

Step-by-step explanation:

a.=Q3 - Q1

=4.7 - 2.2

=2.5

b. =2/5 × 100/1

=40%

Answer:

n<-12

Step-by-step explanation:

4<-1/3n

4<-n/3

4×3<-n

12<-n

-12<n

n<-12

Answer:

P = 45 W

Step-by-step explanation:

Given that,

The weight of a box, W = 90 N

Distance moved, d = 10 m

Time, t = 20 s

We need to find the amount of power used. The rate of doing work is called power It can be calculated as the formula,

[tex]P=\dfrac{W}{t}\\\\P=\dfrac{Fd}{t}\\\\P=\dfrac{90\times 10}{20}\\\\P=45\ W[/tex]

So, 45 W of power was used.

Answer:

$1050

Step-by-step explanation:

I = PRT / 100

I = 21

P = ?

R = 4%

T = 6 months = 0.5 yr

P = 100I / RT

P = (100 * 21) / (4 * 0.5)

P = $1050

The answer is perpendicular :]

Answer:

26/5

Step-by-step explanation:

an=a1+(n-1)d

d is common difference

so,

2/5- (-2)=12/5

putting values in above formula

 =-2+(4-1)(12/5)

=-2+3(12/5)

=-2+(36/5)

=26/5
