Answer:
decrease by 35%
Step-by-step explanation:
0.65 is only 65% of a whole number, so it decreases the original number by 35%
First compute the mean:
(4.67 + 4.98 + 4.34) / 3 = 4.66
then compute the variance:
(4.67-4.66)^2 = 0.0001
(4.98-4.66)^2 = 0.1024
(4.34-4.66)^2 = 0.1024
sum of the three = 0.2049
then take the square root:
= 0.452
the standard deviation is 0.452
The answer is 9:16 just add 9+7=16 and then we know out of the 16 nine were dogs so 9:16
Answer: a) (5 - 7)²
<u>Step-by-step explanation:</u>
g(x) = x^2 h(x) = x - 7
h(5) = 5 - 7
g(h(5)) = g(5 - 7) = (5 - 7)² <em>Replace the x in g(x) with (5 - 7)</em>
