Suppose 40% of the population of pre-teens have a TV in their bedroom. If a random sample of 500 pre-teens is drawn from the population, then the probability that between 36% and 44% of the pre-teens have a TV in their bedroom is:___________
a) 0.9644
b) 0.4644
c) 0.0356
d) 0.9328
e) 0.0712
Answer:
0.9328
Step-by-step explanation:
The mean of the sampling distribution is equal to
up = p = 0.40
The standard deviation = √pq/n
= √0.40x0.60/500
= √0.00048
= 0.0219
We compute the z values for the probability of 36% and 44%
When p = 0.36
z = 0.36-0.40/0.0219
= -1.83
When p = 0.44
z = 0.44-0.49/0.0219
= 1.813
From the standard normal distribution table. The probability associated with z values from Which we subtract the probability
P(0.36<=p<=0.44)
= P(-1.83<=z<=1.83)
P(z<=1.83)-p(z<=-1.83)
= 0.9664-0.0336
= 0.9328
Therefore the answer is 0.9328

Parallelogram ABCD is undergoing a series of transformations. Which of the following transformations will NOT result in a shape congruent to parallelogram ABCD?
A. translation 4 units to the left
B. reflection over the y axis
C. dilation with a scale factor of 2
D. rotation of 270 degrees clockwise
Answer:
C
Step-by-step explanation:
The answer would be C because dilation ( unless by 1 ) doesn't preserve congruence so every other answer that isn't dilation would be right and C would be the answer because the factor is 2 not 1.

What is a number line?In Geometry and Mathematics, a number line refers to a type of graph that is usually composed of a graduated straight line, which typically comprises both negative and positive numerical values (numbers) that are located at equal intervals along its length.
Assuming the variable J represent John's score and the variable K represent Kamira's score on the number line. In this scenario and exercise, we would determine the solution for the given scenario by solving as follows;
J + K = 1 + 7 = 8
K - J = 7 - 1 = 6
|K - J| = |7 - 1| = |6| = -6

When 848 is divided by n, the result is 16.
Answer:
n = 53
Step-by-step explanation:
Write the equation like this to find the answer.
848/n = 16 (Multiply each side by n to get 848 by itself)
848 = 16n (divide each side by 16 to get n by itself)
53 = n
CHECK
848/53 = 16
16 = 16

Suppose you have £20,000 in cash to invest. You decide to short sell £10,000 worth of Coca-Cola and invest the proceeds from your short sale plus your £20,000 in Intel. The initial price of Coca-Cola is £40 and increases to £42.40 producing a return of 6%. The initial price of Intel is £25 and increases to £31.50 producing a return of 26%. How many shares of Coca-Cola have you short sold and how many shares of Intel do you currently have? Select one: a. Short sold 2,000 shares of Coca cola and invested in 80 shares of Intel b. Short sold 40 shares of Coca cola and invested in 400 shares of Intel c. Short sold 250 of Coca cola and invested in 1200 shares of Intel d. Short sold 300 of Coca cola and invested in 12000 shares of Intel
Answer:
hdshdhdbs sorry
Step-by-step explanation:
The number of shares of Coca-Cola short sold and number of Intel shares bought are c. Short sold 250 of Coca cola and invested in 1200 shares of Intel.
Data and Calculations:
Cash available for investment = £20,000
Proceeds from short sale of Coca-Cola = £10,000
Total funds available for investment = £30,000
Initial price of Coca-Cola per share = £40
Number of Coca-Cola shares short sold = 250 (£10,000/£40)
Initial price of Intel stock per share = £25
Number of Intel shares acquired = 1,200 shares (£30,000/£25)
Thus, you short sold 250 shares of Coca-Cola stock and invested in 1,200 shares of Intel stock.

A stainless steel patio heater is a square pyramid. The length of one side of the base is 23.4 in. The
slant height of the pyramid is 88.2 in. What is the height of the pyramid?
Answer:
87.4 in
Step-by-step explanation:
Imagine a right triangle with one side the hight the other side half of the base side and the hypotenuse the slant height and use Pythagorean Theorem.
h² + (23.4/2)² = 88.2² solve for hight,
h=√88.2²- (23.4/2)² is about 87.4 in
A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 2% margin of error at a 97.5% confidence level, what size of sample is needed?Give your answer in whole people.
Answer:
The sample size is [tex]n = 3139 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is [tex]E = 0.02[/tex]
From the question we are told the confidence level is 97.5% , hence the level of significance is
[tex]\alpha = (100 - 97.5% ) \%[/tex]
=> [tex]\alpha = 0.025[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.241 [/tex]
Generally we will assume the sample proportion to be [tex]\^ p = 0.5[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n = [\frac{2.241}{0.02} ]^2 *0.5 (1 - 0.5 ) [/tex]
=> [tex]n = 3139 [/tex]
