Answer:
option B.
About 16% of the books have fewer than 150 pages
Step-by-step explanation:
Since we are dealing with a normal distribution
68.27% of the values will fall in the range with the standard deviation
(180-30 , 180+30) = (150, 210)
Approximately 15.86% of the values will be higher than 210
and the rest 15.86% will be lower than 150
So the correct answer is option B.
About 16% of the books have fewer than 150 pages
Question is not Proper.The Proper Question is given below.
∠P and ∠Q are complementary. m∠P = 52° and m∠Q = (3x + 2)°. Find the value of x. Show your work.
Answer:
Therefore the value of x is
Step-by-step explanation:
Given:
∠P and ∠Q are complementary.
m∠P = 52° and
m∠Q = (3x + 2)°.
To Find:
x = ?
Solution:
Complementary Angles:
Two angles are Complementary when they add up to 90 degrees.
Example 40° and 50° are Complementary Angles.
If 'x' and 'y' are Complementary Angles the we have
Here, ∠P and ∠Q are complementary.
Substituting the values we get
Therefore the value of x is
Answer:
The location of the point that is 3/4 the distance from is .
Step-by-step explanation:
Let and the endpoints of the segment, we can determine the location of the point that is 3/4 the distance from by the following vector equation:
(1)
If we know that and , the location of is:
The location of the point that is 3/4 the distance from is .
probability that a randomly chosen college student either has a job or lives on campus.
What is probability?
- Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
- The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
To find the probability that a randomly chosen college student either has a job or lives on campus:
Given: 85% of college students have a job, 54% live on campus, and 42% have a job and live on campus.
So, out of 100 students, 42 students either has a job or live on campus.
43 college students have a job and 12 live on campus.
So, 43 + 42 + 12 = 85 + 54 - 42
85 + 12 = 139 - 42
97 = 97
Therefore, probability that a randomly chosen college student either has a job or lives on campus.

Answer:
11 3/4 miles.
Step-by-step explanation:
Converting to improper fractions, the consecutive distances are:
21/4 , 55/8, 17/2
= 42/8, 55/8, 68/8 for Monday, Tuesday and Wednesday.
So the distances have increased by 13/8 miles each day.
Thus number of miles he'll bike on Friday = 68/8 + 2(13/8)
= 94/8
= 11 3/4 miles.
