<h3>
Answer:</h3>
A, D
Step-by-step explanation:
for this table:
x 0 5 10 15 20 25 30 35 40
f(x) 5 6 7 8 9 10 11 12 13
A, assuming it's supposed to say f(5)=6, is true since 5 in x corresponds to 6 in f(x)
B is false, since the domain would be the set of all numbers in x, since domain corresponds to input (x) and range corresponds to output (f(x))
C is false, the range is not all real numbers since it is a defined set of numbers
D is true, since 15 in x corresponds to 8 in f(x)
Therefore, A and D are true
Answer:
x=200
Step-by-step explanation:
let 'x' represent the total number of students
0.40x of the students voted for Gerardo
0.35x of the students voted for Leandro
0.25x of the students voted for Juju
70 students voted for Leandro:
0.35x = 70
by solving we find:
x = 200 students
Answer:
Combinations refer to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection, k-multiset, or k-combination with repetition are often used.
Step-by-step explanation:
in smaller cases it is possible to count the number of combinations. For example given three fruit, say an apple, orange and pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange.
Answer:
P(5R) = 0.60^5
P(5R) = 0.07776 = 0.078
Therefore the probability that it will be effective in each of five (5 out of 5) separate trials is 0.078
Step-by-step explanation:
Given;
The probability that the rhythm method of contraception is effective once is P(R) = 0.60
The probability that it will be effective n times is;
P(nR) = 0.60^n
For this case n= 5
P(5R) = 0.60^5
P(5R) = 0.07776
P(5R) = 0.078
