The inverse is b. If 4x+1 .NE. 61, then x-5 .NE.10
Answer:
a) 0.72
b) 0.98
Step-by-step explanation:
We are given the following information in the question:
P(passing maths exam) = P(m) = 0.9
P(passing Spanish exam) = P(s) = 0.8
It is assumed that the results of the two exams are independent of each other.
a) probability that she passes both exams
By assumption of independence, we can write:
0.72 is the probability that Josie will pass both the exams.
b) probability that Josie passes at least one of the exam
0.88 is the probability that Josie passes at least one of the exams.
The last option c is right because each book selected represents the sample from the population of full library books.
We have given that,
Sahira chooses a random sample from the library and records the type of books in the chart below.
Type of Book Number
Fantasy 10
Literature 25
Children’s 4
Nonfiction 11
t, showing the distribution of the number of books in a library.
Also given that Sahira chooses a random sample from the library and records the type of books in the chart below.
Sahira's sample can be said to be representative because given that books are taken at random.
So just because books literature more we cannot say it is not representative II option is not right, because each book was not chosen uniquely, just random books were drawn.
<h3>
What is the population?</h3>
A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.
The last option c is right because each book selected represents the sample from the population of full library books.

Answer:
The answer is the third option, C = 5 + 0.25m
Step-by-step explanation:
We already know that the official price for the taxi is 5 dollars, so we aren't multiplying that value by anything.
However, the text mentions that for each mile, Maria is taxed an extra .25 cents. Therefore, you have to add the base amount, 5, plus the 25cent with the m next to it to symbolize that however many miles she goes, the 25 cents will be multiplied by that value.
Answer:
-613/716.
Step-by-step explanation:
The reciprocal of a number is basically that number upside down. to find the reciprocal of a whole number, you can just turn the number into a fraction, and put one as the numerator, and the original number as the denominator. given this information we know that the reciprocal of -716 is -1/716, so now yoj can simply cross multiply 613 by -1/716, which gives you -613/716.
