B. –2.06


C. 1.18


D. 0.35

Answers

Answer 1
Answer:

Answer:

A. Z=2.06

Step-by-step explanation:

We want to find the Z-score of X=27 if the population mean is \mu=20,and the population standard deviation is \sigma=3.4.

We use the formula:

Z=(X-\mu)/(\sigma)

We substitute the values to obtain:

Z=(27-20)/(3.4)

Z=(7)/(3.4)

Z=2.06

The correct answer is A.

A comic-strip writer churns out a different number of comic strips each day. For 16 days, the writer logged the number of comic strips written each day (sorted low to high): {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}. If the writer writes for one more day and comes up with 8 new comic strips, how will the skew be affected?A) The distribution will be skewed to the negative side.

B) The distribution will be skewed to the positive side.

C) The distribution will have the same mean and median.

D) The distribution will have a mean lower than the median.

Answers

The distribution will be skewed to the positive side, the correct option is B.

What is mean?

Mean is the average of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.

The data of the comic strips written is

{1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}

Mean = 54/16

Mean = 3.375

Median = 3

When 8 is added to the data

Mean = 3.64

Median = 3

The Mean > Median, so the distribution will be skewed to the positive side.

How do you solve 4(6x-1)=120 if you're solving for x

Answers

4(6x-1)=120
Multiply the number outside the parenthesis(4) with the numbers inside the parenthesis(6 and -1)
24x-4=120
Add 4 to both sides
24x=124
Divide both sides by 24
Final Answer: x= 5.1667 or 5 1667/10,000

Whats the integral of 1/X

Answers

F(x) = \int\limits (1)/(x) dx =\int\limits x^-^1 dx \n f(x) = \int\limits x^-^1dx = (1)/(0) X^0

= f(x) = \int\limits X^-^1dx = In|x|
$\left(\ln(|x|)\right)'=\frac{1}x$ hence \int\frac{1}xdx=\ln |x|
