<h3>What is a sample size?</h3>
Sample size is the number of participants or observations that are included in a study. This is usually represented by n.
When the boys and girls are to be chosen, the new sample size based on the information will be B-M, B-C, B-R, 8.

Answer: FALSE
Actually, the answer to this question depends on whether the clause is reversed or not.
Since we are not told whether the the clause is reversed or not. It is safe to assume that it was retained (i.e. not reversed). So the answer to this question is FALSE because if one takes a true "if-then" statement, inserted a 'not' in each clause, and retained the clauses, the new statement would NOT be true.
On the contrary, if the clause is reversed, the answer would be TRUE, because if one takes a true "if-then" statement, inserted a not in each clause, and reversed the clauses, the new statement would also be true.
Given maria has in the pennies & quarters.
she has twice as many pennies as quarters.
find out the coins
let us assume the quarters are x
than the pennies are 2x.
Formula
value of the pennies + value of the quarters = total value of coins
1 quarters =$ 0.25
1 pennies = $0.01
Thus
0.25x + 0.01 (2x) = 2.43
0.27 x = 2.43
x = 9
2x = 18
i.e the number of quarters are 9 and the number of pennies are 18.
Hence proved
Answer:
x = - 2, x = 9
Step-by-step explanation:
Given
f(x) =
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0
(x - 9)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 9 = 0 ⇒ x = 9
The excluded values are x = - 2, x = 9
