What are the angles?
if all of them are below 90 degrees, it is acute.
if one angle is 90 degress, it is right
if one angle is more than 90 degrees, it is obtuse
A) f(x) = 2x - 3
f(0) = 2(0) - 3
f(0) = 0 - 3
f(0) = -3
b) f(x) = 2x - 3
f(-2) = 2(-2) - 3
f(-2) = -4 - 3
f(-2) = -7
c) f(x) = 2x - 3
f(3) = 2(3) - 3
f(3) = 6 - 3
f(3) = 3
d) f(x) = 2x - 3
f(-1) = 2(-1) - 3
f(-1) = -2 - 3
f(-1) = -5
Answer:
c. the biology test
Step-by-step explanation:
To answer this problem we need to calculate the z-score of both tests, using the formula:
z = (x - μ) / σ
Where x is Sue's score, μ is the mean, and σ is the standard deviation.
- For the <u>biology test</u>, the z-score is:
z = (76 - 70) / 7 = 6/7 = 0.857
- For the <u>math test</u>, the z-score is:
z = (76 - 75) / 10 = 1/10 = 0.100
Because the z-score for the biology test is greater than the z-score for the math test, Sue did better in the biology test, in comparison to the rest of the class.
Answer:
<u>The correct answer is B. 36</u>
Step-by-step explanation:
1. Let's review the information given for answering the question correctly:
Data set given:
18
36
11
45
36
19
14
18
36
2. What is the mode for this data set?
Let's recall that the Statistical Mode is the number that is more frequently repeated in a group of numbers. If no number is repeated, then there is no mode for the list or set.
In this specific set, we can notice that 18 is repeated two times and 36 is repeated three times. Therefore, the mode for this set of ages of people riding a bus is 36.
<u>The correct answer is B. 36</u>
I don't know because of the denomination at the end
