Answer:

B: The mean is 0 and the distribution will not be approximately normal

Step-by-step explanation:

It is true that the mean is 0 because it is the difference in the population proportions, 0.01−0.01. However, normality cannot be assumed because the sample sizes are not large enough.

The sample distribution is defined as the probability distribution of a given sample based on statistics.

The correct option is (a).

Given:

The defective parts produced by each machine is 1%.

The sample Size is 100.

Calculate the proportion of the defective parts.

[tex]\dfrac{1}{100}=0.01[/tex]

Thus, the mean of each machine is 0.01.

Now, the mean difference between both machine is 0 and proportion will be normally distributed.

Answer:

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value lower than x is given by:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

Uniformly distributed between 22 and 29, in units of thousands of dollars.

This means that [tex]a = 22, b = 29[/tex].

(a) Find the probability that the low bid on the next intrastate shipping contract is below $25,000.

This is P(X < 25). So

[tex]P(X < 25) = \frac{25 - 22}{29 - 22} = 0.4286[/tex]

0.4286 = 42.86% probability that the low bid on the next intrastate shipping contract is below $25,000.

Answer:

y= –x + 1

Step-by-step explanation:

to write an equation in slope-intercept form, y = mx + b, calculate the slope, m, as rise/ run

The difference in y-values, rise, is –2

The difference between x-values is 2

–2/2 = m, the slope is –1

substitute for m, and it use any set of given y and x values in the equation to solve for b.

y= mx +b

–2 = –1(3) + b. Add 3 to both sides.

3 –2 = 3 –3 + b

1 = b

use the calculated m and b to write the equation with y and x

y = –x + 1

Explanation: Decimals represent fractions

with denominators of 10, 100, 1000, and so on.

Therefore, in order to write 3/5 as a decimal, we must first find a

fraction equivalent to 3/5 with a denominator of 10.

So we multiply the numerator and denominator

of 3/5 by 2 to get the equivalent fraction 6/10.

Since 6/10 is written as the decimal 0.6,

3/5 must be equivalent to 0.6.

Answer:

They saved $3000 in 2014

Step-by-step explanation:

Given

[tex]Savings (2013) = \$12500[/tex]

[tex]Total (2014) = \$15500[/tex]

Required

Determine the savings in 2014

This is calculated by subtracting the savings in 2013 from the total savings.

i.e.

[tex]Savings(2014) = Total(2014) - Savings(2013)[/tex]

This gives:

[tex]Savings(2014) = \$15500 - \$12500[/tex]

[tex]Savings(2014) = \$3000[/tex]

Hence, they saved $3000 in 2014

Answer:

The numbers described here are 39 and 11.

Step-by-step explanation:

Let's call the numbers a and b, a being the larger. We're told two things:

The larger of the two numbers is 17 more than twice the smaller.

Which we can express as:

a = 2b + 17

When the larger number is divided by the smaller, the quotient is 3 and the remainder is 6

And that can be expressed as:

a = 3b + 6

We can now take those two expressions and, noting that they both define a, we can say that they are equivalent, and solve for b:

2b + 17 = 3b + 6

3b - 2b = 17 - 6

b = 11

With b found, we can now take either of the first expressions, and solve for a:

a = 2b + 17

a = 2(11) + 17

a = 22 + 17

a = 39

Now we can check whether that is correct by plugging it into the other expression and seeing if b still comes to 11:

a = 3b + 6

39 = 3b + 6

3b = 33

b = 11

So we know that the answer is correct.

The value of [x] will be equivalent to x = 3.5.

        [tex]y=log_{e} (x)[/tex]

Given is the logarithmic equation as

2log(4x) − log(49) = 2

2log(4x) = 2 + log(49)

2{log(4) + log(x)} = 2 + log(49)

{log(4) + log(x)} = {2 + log(49)}/2

log(4) + log(x) = 1 + log(49)/2

log(4) + log(x) = 1.85

log(x) = 1.85 - log(4)

log(x) = 1.25

x = e^(1.25)

x = 3.5 {approx.}

Therefore, the value of [x] will be equivalent to x = 3.5.

Answer:

The charges will be the same after 10 miles.

Step-by-step explanation:

Long Beach Towing Company:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

[tex]L(x) = 40 + 5x[/tex]

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

[tex]F(x) = 70 + 2x[/tex]

After how many miles the charges for the two companied will be the same?

This is x for which:

[tex]L(x) = F(x)[/tex]

So

[tex]40 + 5x = 70 + 2x[/tex]

[tex]5x - 2x = 70 - 40[/tex]

[tex]3x = 30[/tex]

[tex]x = \frac{30}{3}[/tex]

[tex]x = 10[/tex]

The charges will be the same after 10 miles.
