Answer:

426 square feet

Step-by-step explanation:

First, find the angle of each shape separately.

Area of a triangle = 1/2 base times height

1/2(9x8)

1/2(72) = 36

Area of a rectangle = base times height.

26 x 15 = 390

Now, add the numbers together to get the total area. 390+36=426

Answer:

426 square feet

Step-by-step explanation:

-First find the area of the rectangle:

26 x 15 = 390

-Next, find the area of the triangle on top:

9 x 8/2 = 36

-Finally, add the two to get the full area of the figure:

390 + 36 = 426

Answer: 426 square feet

Answer:

[tex]s = 1[/tex]

Step-by-step explanation:

Given

[tex]s - \frac{1}{2} = \frac{1}{2}[/tex]

Required

Solve for s

[tex]s - \frac{1}{2} = \frac{1}{2}[/tex]

Add [tex]\frac{1}{2}[/tex] to both sides

[tex]s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}[/tex]

Take LCM

[tex]s + \frac{-1+1}{2} = \frac{1+1}{2}[/tex]

[tex]s + \frac{0}{2} = \frac{2}{2}[/tex]

[tex]s +0 = 1[/tex]

[tex]s = 1[/tex]

Options:

Ha : µ<12

We formulate the null and alternative hypothesis here to state that battery life of the laptop lasts at least 12 hours(more than but not less, null hypothesis) or that it lasts less than 12 hours(alternative hypothesis).

The null hypothesis is the one being tested to know whether we would reject it or not in which case we choose the alternative hypothesis. To test the hypotheses, we do a t test using a significance level of say 0.05(95% confidence interval) and find our p value in order to compare and decide if the null hypothesis would be rejected or not based on statistical significance.

Answer:

a) [tex]x=2p-4[/tex]

b) our team scored 44 points

Step-by-step explanation:

Your basketball team scored 4 fewer than twice as many points p as the other team.

a) Write algebraic expression

Let x is your basketball team score, the expression will be:

[tex]x=2p-4[/tex]

b) The other team scored 24 points. How many points did your team score?

p=24

we need to find x

[tex]x=2p-4\\Put \ p=24\\x=2(24)-4\\x=48-4\\x=44[/tex]

So, our team scored 44 points

Answer:

D

Step-by-step explanation:

189 boys is 54%

x is 46%(100-54)

Cross multiply:

189*46%=54%*x

86.94=0.54x

x=161

189 boys 161 girls

350 altogether

Answer:

The answer is "0.9217".

Step-by-step explanation:

Please find the complete question in the attached file.

[tex]\mu = 218.4 \\\\ \sigma = 25\\\\\bar{x}= 224 \\\\ n = 40 \\\\[/tex]

[tex]z = \frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}}}\\[/tex]

[tex]= \frac{224 - 218.4}{\frac{25}{\sqrt{40}}} \\\\= 1.4167\\\\\to P( \bar{x}< 224) = P(z< 1.4167) = 0.9217[/tex]

Answer:

11pi/6 in^3 or

5.760 in^3 to the nearest thousandth.

Step-by-step explanation:

Volume of ice cream = volume of the cone + volume of the hemisphere

= 1/3 pi r^2 h + 1/2 * 4/3 pi r^3    

= 1/3 pi 1^2 * 3.5 + 2/3 pi 1^3             (as the radius = 1/2 * diameter)

=  (7/6 + 2/3) pi

= 11pi/6 in^3.

Answer:

20.6

Step-by-step explanation:

The exponential function to solve the problem.

A = [tex]A_0[/tex] [tex]e^{rt}[/tex]

A = population in time t.

[tex]A_0[/tex] = Initial population.

r = growth rate.

t = time

The number of days taken to triple the population is 20.7 days.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The exponential function to solve the problem.

A = [tex]A_0[/tex] [tex]e^{rt}[/tex]

A = population in time t.

[tex]A_0[/tex] = Initial population.

r = growth rate.

t = time

Now,

A = 2[tex]A_0[/tex]

t = 13

A = [tex]A_0[/tex] [tex]e^{rt}[/tex]

[tex]2A_0[/tex] = [tex]A_0e^{13r}[/tex]

2 = [tex]e^{13r}[/tex]

Taking logs on both sides.

log 2 = 13r log e

0.30 = 13r

r = 0.30/13

r = 0.023

Now,

A = 3[tex]A_0[/tex]

A = [tex]A_0[/tex] [tex]e^{rt}[/tex]

3 = [tex]e^{rt}[/tex]

log 3 = rt

0.48 = 0.023t

t = 0.48/0.023

t = 20.7 days.

Thus,

The number of days taken to triple the population is 20.7 days.
