Answer:
B. Statistic
Step-by-step explanation:
The average weight of those questioned which is 157 lb. from the survey of 40 randomly selected member of a health and fitness club is an example of a statistic.
It is a calculated numerical value that characterises some aspects of a sample set of data.
Statistic refers to a numerical piece of information that uses quantified models, representations and synopses for a given set of a study. Statistic is used to to estimate the true value of a parameter in a population.
Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation 
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation
we can find time t
We have h(t)=40

Now, we will solve the quadratic equation using quadratic formula: 
We have a =16, b=-120 and c=32
Putting values and finding t

So, we get t= 7.22 and t=0.28
The correct options are Option A and Option G
The answer is 12. Substitute a for 12 and b for 7 in the equation. Multiply first, then add/subtract from left to right
If you would like to find a function which is equivalent to f(x) = 3(1.7)4x, you can do this using the following steps:
<span>f(x) = 3(1.7)4x = 3(1.7)^(4x) = 3(1.7^4)^x = 3(8.35)^x = 3(8.35)x
</span>
The correct result would be B <span>f(x) = 3(8.35)x.</span>
