Answer:

volume= 3054.86cm^3

Step-by-step explanation:

Answer: 45?

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

Answer:

Step-by-step explanation:

The volume should be 9 to the second power times 4×3.14

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:

56.25

Step-by-step explanation:

100% of 56.25 is 56.25, therefore 32% of 52.25 equals 18

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:

0 or 1.110838652

Step-by-step explanation:

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:

$14.41

Step-by-step explanation:

set up a proportion then cross-multiply:

12.75 / 46 = x / 52

46x = 663

x = 14.41

Answer:

t = 0

Step-by-step explanation:

Answer:

t = 5/3

Step-by-step explanation:

t - 5/ 6 = 5/ 6

t = 5/6 + 5/6

t = 10/6

t = 5/3

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.

Answer:

y = [tex](\frac{1}{2})^{-x} +4[/tex]

Step-by-step explanation:

In order to achieve the following transformation we need to do the following. To get the graph to be reflected accross the y-axis we need to change the sign of the x variable. Since the x-variable in this scenario is a positive we would change it to a negative. Next, we want to shift the graph 4 units up. To do this we simply need to add 4 to the entire equation. This would result in the following equation.

y = [tex](\frac{1}{2})^{-x} +4[/tex]

Both of these graphs can be seen in the image below.

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

Answer:

f(3) = 7

Step-by-step explanation:

f(x) = 2x + 1

f(3) = 2(3) + 1

f(3) = 6 + 1

Substitute the 3 in for x.

f(3) means that x is equal to 3.

This just means we substitute the value of 3 into the f(x) = 2x+ 1 to get

f(x) = 2(3)+ 1,

f(3) = 2(3)+ 1,

f(3) = 6+ 1,

f(3) = 7

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:

Answer: 6.30

Step-by-step explanation:

4 and below let it go, five and above give it a shove

The 5 in the thousandths place tells us that we need to raise the 9 in the hundredths place to 10, so we have to carry the 1 to the tenths place and add 2 + 1

Answer:

P = 55 feet

A = 237 sq feet

Step-by-step explanation:

P = 2(4) + (3.14 x 15)

A = (4 x 15) + (3.14 x 7.5²)

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
