Research in March 2019 suggests that 40% of U.S. Adults approve of way President Trump is running the country. We randomly sample 50 U.S. Adults and find that 35% approve of way President Trump is running the country. What is the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion? (Round standard error to 2 decimal places before calculating Z. Round Z to 2 decimal places before using the Normal Distribution Calculator.) Group of answer choices about 0.24 about 0.76 about 0.48
Answer:
The probability is [tex]P( \^ p < 0.35)= 0.2388 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.40
The sample size is n = 50
Generally the standard error is mathematically represented as
[tex]\sigma_{\= p} = \sqrt{\frac{p * (1- p)}{n} }[/tex]
=> [tex]\sigma_{\= p} = \sqrt{\frac{0.40 * (1- 0.40)}{50} }[/tex]
=> [tex]\sigma_{\= p} = 0.07[/tex]
Generally the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion is mathematically represented as
[tex]P( \^ p < 0.35) = P(\frac{\^ p - p}{\sigma_{\= p}} < \frac{0.35 - 0.40}{0.07} )[/tex]
Generally [tex]\frac{\^ p - p}{\sigma_{\= p}} = Z (The \ standardized \ value\ of \ \^ p )[/tex]
=> [tex]P( \^ p < 0.35)=P(Z < -0.71)[/tex]
From the z table
[tex]P(Z < -0.71) = 0.2388[/tex]
So
[tex]P( \^ p < 0.35)= 0.2388 [/tex]

Zach wants to make a profit of more than 300 for painting 4 identical too rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is 32.50 for each room. Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than 300
Given :
Zach wants to make a profit of more than 300 for painting 4 identical too rooms.
The cost of supplies is 32.50 for each room.
To Find :
Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than $300.
Solution :
Profit is given by :
Profit = S.P - C.P
Now, it is given that profit > 300 .
Profit = S.P - C.P > 300
[tex]4n - 4\times 32.5 > 300\\\\n - 32.5 > 75\\\\n > \$107.5[/tex]
Hence, this is the required solution.

Step-by-step explanation:
Answer:
-2

Solve the formula for the area of a parallelogram the height,
h.
A = bxh
h= _(use the / symbol to show division)
Answer:
h=A/b
Step-by-step explanation:
Think of putting number in the place of the letter, for example
A is 4
b is 2
h is 2
4=2 x 2 then plug the numbers in the right spot
2=4/2 then see what can be rearranged or what is left to make the
equation true

3) The height of an object that is thrown straight up from a height of 6 feet
above ground is given by h(t) = -15t2 + 25t + 6, where t is the time in
seconds after the object is thrown. Find the average rate of the object from
1 to 4 seconds.
Answer:
- 44 feets
Step-by-step explanation:
Given the model:
h(t) = -15t2 + 25t + 6
Average height of object from 1 - 4 seconds
At :
t = 1
h(1) = -15(1)^2 + 25(1) + 6 = 16 feets
t = 2
h(2) = -15(2)^2 + 25(2) + 6 = - 4 feets
t = 3
h(3) = -15(3)^2 + 25(3) + 6 = - 54 feets
t = 4
h(4) = -15(4)^2 + 25(4) + 6 = -134 feets
Average height:
(16 + (-4) + (-54) + (-134)) / 4 feets = (- 176 / 4) feets
= - 44 feets

It normally takes Julius 2 hours to mow the yard, but because he is in a hurry he asks his son, Marcos, to help him. If just his son was doing the yard work it would take him 3 hours. How long will it take if both are working together? Use the formula 1/T_1 +1/T_2 =1/T_both where T_1 is the time required for Julius to complete the job alone, T_2 is the time required for Marcos to complete the job alone, and T_both is the time required to complete the job when they both work together. Answer as a decimal, rounded to one decimal place.
Answer: 1.2 hours
Step-by-step explanation:
Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]
Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]
Let the time taken by both to complete the job together = T
[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]
[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]
Hence, it will take 1.2 hours to complete the job by working together.

Answer:
3x^3 + 3x^2 - 27x - 27
Step-by-step explanation:
===============================================
Work Shown:
(x+3)(x-3)(3x+3)
(x^2-9)(3x+3) .... difference of squares rule
y(3x+3) .... let y = x^2-9
y*3x + y*3 .... distribute
3x( y ) + 3( y )
3x( x^2 - 9 ) + 3(x^2 - 9) .... plug in y = x^2-9
3x*x^2 + 3x*(-9) + 3*x^2 + 3*(-9) .... distribute
