There are twenty books on a shelf. Ten of them are science books, two are social studies, seven are math, and one is reading. What is the probability of choosing a science book, replacing it and then choosing another science book?
Answers
Answer: 1/4
Step-by-step explanation: Probability is favorable outcomes/ all outcomes, to first choose a science book, the probability is 10/20, or one-half, and then to pick one again, is also 1/2, so you multiply them together to find the probability of both happening and you get 1/4!

Doug's teacher told him that standardized score (s-score) for his mathematics exam, as compared to the exam scores of other students in the course, is 1.20.
Answers
Full question:
Doug's teacher told him that the standardized score (z-score) for his mathematics exam, as compared to the exam scores of other students in the course, is 1.20. Which of the following is the best interpretation of this standardized score?
Doug's test score is 120.
Doug's test score is 1.20 times the average test score of students in the course.
Doug's test score is 1.20 above the average test score of students in the course.
Doug's test score is 1.20 standard deviations above the average test score of students in the course.
None of the above gives the correct interpretation.
Answer:
Doug's test score is 1.20 standard deviations above the average test score of students in the course.
Explanation:
Z scores are also known as standardized scores or normal scores or standardized variables. Z scores are used to standardize raw data in order to give them a uniformity or standard that allows for easier comparison of data values. For us to calculate a z-score as was done in Doug's test score, we simply subtract the mean from the raw data score and we divide the answer by the standard deviation.

Which of the following statements about the graph of y = 3x - 5 are true? Select all that apply.
A.
The y-intercept is -5.
B. The x-intercept is 3.
C. (2, 1) is a point on the graph.
D. As the x-values increase, the y-values also increase.
Answers
The y-intercept is -5 and as the x-values increase, the y-values also increase in this graph of the line. which is the correct answer would be options (A) and (D).
What is a graph?
A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is the equation of a line?
The general equation of a line is y = mx + c
where m is the slope of the line and c is the intercept.
A linear equation is defined as an equation in which the highest power of the variable is always one.
We have been given that function of the line as
y = 3x - 5
We need to determine the y-intercept.
The y-intercept is at x = 0, y = -5
And the x-intercept is at y = 0, x = 5/3
Here In this graph of the given function as the x-values increase, the y-values also increase.
Therefore, the correct answer would be options (A) and (D).

Answer:
arc CD = 160°
Step-by-step explanation:
The measures of the arcs on the circle = 360° , then
arc CD = 360 - AC - AD = 360 - 3x - 7x = 360 - 10x
--------------------------------------------------------------------------
The measure of the secant- tangent angle ABC is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (7x - 3x) = 40 ( multiply both sides by 2 to clear the fraction )
7x - 3x = 80
4x = 80 ( divide both sides by 4 )
x = 20
Then
CD = 360 - 10x = 360 - 10(20) = 360 - 200 = 160°

You have two values you need to pay attention to:
The length that is adjacent to the 74°C, 25 ft. And the length opposite of the 74°C, the height of how high the rocket traveled.
So adjacent and opposite, O & A. "Toa", find the tangent of 74°C.

Answer : 1/2 gallon
Explanation:
There were a total of 5 gallons collected, as the question states.
There are 3 x's above 1/4, 2 x's above 3/8, 4 x's above 5/8 and 1 x above 1. This is a total of
3+2+4+1 = 10 x's. This means there were 10 trees.
If 5 gallons is evenly distributed among 10 trees, this would give us the ratio 5/10, which simplifies to 1/2 gallon per tree.
