Answers

The volume of the sphere is 2144.7cm³.

Given that a sphere with radius 8 cm.

As we all know that the volume of sphere is 4/3πr³.

We will find the volume of sphere by substituting the value of radius in the formula, we get

Volume=4/3 πr³

Now, we will substitute r=8 cm in above formula, we get

V=(4/3)π(8 cm)³

V=(4/3)π(512)cm³

Now, we will simplify this by multiply by 4, we get

V=(2048/3)πcm³

Now, we will simplify it by dividing it with 3, we get

V=682.66π cm³.

As we know, the value of π is 3.14.

So, we will substitute this value and simplify it, we get

V=682.66×3.14

V=2144.66 cm³

Hence, the volume of the sphere when the radius is 8cm is 2144.7 cm³.

the sum of four numbers is 1,764. oneof the numbers, n, is 40% more than the sum of the other three numbers. what is the value of n?

Answers

Four numbers has a sum of 1764 and the value of one of those numbers is 1029.

Use algebraic expressions to solve for the value of n.

Algebraic expression is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc).

One of the four numbers is already denoted as variable n. Let m be the sum of the three other numbers.

If the sum of the four numbers is 1,764, then:

n + m = 1764

If n is 40% more than the sum of the other three numbers, then:

n = 40% m + m

n = 1.4 m

Substitute n from the 2nd equation to the 1st equation.

n + m = 1764

1.4 m + m = 1764

2.4 m = 1764

m = 735

Recall that n = 1.4 m.

n = 1.4 (735)

n = 1029

jean gray earns a graduated commission of 4 on her first $2000 of sales and 8 on all sales over $2000 jean's sales for the past week totaled $3925

Answers

Her commission for the week was $234.

It is given the total earning in past week = $3,925  and jean earns 4% for the first $2000

So, the commission = $2000 x 4/100  = $80

To find additional sales, the formula to refer is

Add –on sales = total sales – base sales

                          = 3,925 – 2000

                          = 1,925

For the $1,925 sales, Jeans earns 8% commission, Her commission

                                                     = 1,925*0.08    = $154

So, the total commission = $80 + $154  = $234

consider an infinite set of pairwise independent random variables which are uniformly distributed between 0 and 1. what's the expected number that you need to add to get a number that exceeds 1.

Answers

When two random variables X and Y are considered to be independent, it means that neither X's distribution nor Y's values have any bearing on the other.

What do you mean by independent random variable?

A random variable is a variable used in an experiment, such as the number of coin tosses or card draws. An independent random variable is a random variable in your experiment that doesn't affect the other random variables. In other words, it has no impact on the likelihood that another event will occur. For illustration, suppose you randomly selected 50 bags of sugar from various grocery stores in order to determine the average weight of a bag of sugar. The factors are independent since you wouldn't anticipate the weight of one bag having an impact on another. A dependent random variable, on the other hand, does have an impact on the probability of other random variables.

a national survey conducted among a simple random sample of 1,507 adults shows that 56% of americans think the civil war is still relevant to american politics and political life.

Answers

a)

[tex]z=4.658\\p_v=P(z > 4.65)=1-P(z < 4.65)=1.581x*10^{-6}[/tex]

b) By assuming a significance level of α = 0.05 and observing that [tex]p_v[/tex] > α, we can reject the null hypothesis at this level of significance. And in this instance, it makes sense that more than 50% of Americans believe that the Civil War still has an impact on American politics and political life.

c) The confidence interval at 90% would be shown (0.527;0.593).

About 54% to 59% of all Americans, in our opinion, believe that the Civil War is still significant today.

What is a survey?

A survey is a set of questions used in human subject research with the goal of gathering specific information from a certain population. Surveys can be carried out via the phone, by mail, online, at street corners, and even in shopping centers.

a)

1) The presented data and the notation "n=1507" refer to the random sample of Americans, "X" denoting the proportion of those Americans in the sample who believe that the Civil War is still significant to American politics and political life, and "p cap" denoting the estimated number of those Americans.

Since the problem specifies that majority  α=0.05 represents the significance threshold, [tex]p_0[/tex] is the number that we wish to test (no given, but is assumed)

Z would stand for the statistic (interesting variable), and [tex]p_v[/tex] for the p value (variable of interest)

P is the percentage of the public that believes that the Civil War still has an impact on American politics and political life.

2) Useful concepts and formulas

The allegation that more Americans than 50% believe the Civil War is still significant to American politics and political life needs to be tested through a hypothesis (Majority). :

Alternative Hypothesis: p[tex]\geq[/tex] 0.5

Null Hypothesis: p[tex]\leq[/tex] 0.5

The proportion is thought to have a normal distribution.

This test for the percentage of union membership has one tail higher.

Verify whether the sample conforms to the presumptions required for the test to be applied.

a) The random sample must be representative; in this situation, there is no mention of this issue, but it is safe to presume that it exists.

b) The sample size must be sufficient.

[tex]np_0=1507*0.5=753.5 > 10\\n(1-p_0)=1507*(1-0.5)=753.5 > 10[/tex]

3. Determine the statistic.

The formula used to calculate the statistic is as follows:

[tex]z=\frac{p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }= \frac{0.56-0.5}{\sqrt{\frac{0.5(1-0.5)}{1507} } }=4.658[/tex]

P value= [tex]p_v=P(z > 4.65)=1-P(z < 4.65)=1.581*x*10^{-6}[/tex]

According to the alternative hypothesis, the following would be the p value:

P value= [tex]p_v=P(z > 4.65)=1-P(z < 4.65)=1.581*x*10^{-6}[/tex]

Using this formula, the confidence interval would be determined.

p ± [tex]z_{\frac{\alpha }{2}}\sqrt{\frac{p(1-p)}{n} }[/tex]

With the value of [tex]\alpha[/tex] and [tex]\alpha _2[/tex], we can get the quantile necessary for the interval in the normal standard distribution for the 90% confidence interval.

[tex]z_{\frac{\alpha }{2} }=2.58[/tex]

adding the following to the formula for the confidence interval:

[tex]0.56-2.58\sqrt{\frac{0.56(1-0.56)}{1507} } = 0.527\\0.56+2.58\sqrt{\frac{0.56(1-0.56)}{1507} } = 0.593[/tex]

Also provided would be the 90% confidence interval (0.527;0.593).

About 54% to 59% of all Americans, in our opinion, believe that the Civil War is still significant today.

And because the interval does not contain the value of 0.5, we can conclude that, at a 90% level of confidence, the percentage of Americans who believe that the Civil War is still relevant to American politics and political life is higher than 0.5. This result is consistent with the result of part b.

What is hemisphere?

Consequently, a hemisphere is a 3D geometric object that is made up of half of a sphere, with one side being flat and the other being a bowl-like shape. It is created by precisely cutting a spherical along its diameter, leaving behind two identical hemispheres.

EXPLANATION; Let ABCDE be the pyramid with ABCD as the square base. Let O and M be the center of square ABCD and the midpoint of side AB respectively. Lastly, let the hemisphere be tangent to the triangular face ABE at P.

Notice that triangle EOM has a right angle at O. Since the hemisphere is tangent to the triangular face ABE at P, angle EPO is also 90 degree. Hence, triangle EOM is similar to triangle EPO.

OM/2 = 6/EP

OM = 6/EP x 2

OM = [tex]6\sqrt{6^2 - 2^2} x 2 = 3\sqrt{2}/2}[/tex]
