So I break it into pieces but if that doesn't work I try my best and I kept trying trying trying until I bring the sides that's the answer
It's asking for a composition function where you insert the function g(x) into f(x).
f(g(x))=10(x+8)+25
f(g(x))=10x+80+25
f(g(x))=10x+105
Answer:
B
Step-by-step explanation:
Answer:
(6.2, 8.8)
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.5 hours
Standard deviation = 1.3 hours
About 68% of adults:
Within 1 standard deviation of the mean. So
7.5 - 1.3 = 6.2 hours
7.5 + 1.3 = 8.8 hours.
So the answer is (6.2, 8.8).
We have been given that Tina designed an electric skateboard that has a speed of 4 miles per hour. Further we are given that in one hour it travels 4 miles, and in 2 hours it travels 8 miles.
We know that speed of any object can be found at any time, irrespective of it being a complete hour or a fractional hour. Therefore, speed of the electric skateboard is an example of continuous data.
The that in one hour it travels 4 miles, and in 2 hours it travels 8 miles have been given so that someone can easily confuse the speed of electric skateboard as a discrete data, but in actual speed of skateboard is a continuous data.
