Answer:
B. The median weight of the dogs in the survey is 57 pounds
Step-by-step explanation:
F(x) = x² - 1
f(2a) = 35
f(2a) = (2a)² - 1 = 35
4a² - 1 = 35
4a² = 35 + 1
4a² = 36
a² = 36/4
a² = 9
a = √9
a = +3 or -3.
Answer:
8.5 or 8½
Step-by-step explanation:
Arranged numbers in ascending order
2, 6, 8, 8, 9, 10, 12, 14
Median = middle number i. e 8 and 9
Therefore median = 8 + 9 divided by 2
= 17 divided 2
= 8.5
Answers = 8.5 or 8½
The correct answer is x+b/a
f^{-1}(x)=\frac{x+b}{a}
