Answer:
f(-2) = 5
Step-by-step explanation:
To find f(-2), plug in -2 wherever there is an x.
f(x) = 4x² + 3x - 5
f(-2) = 4(-2)² + 3(-2) - 5
f(-2) = 4(4) + 3(-2) - 5
f(-2) = 16 - 6 - 5
f(-2) = 10 - 5
f(-2) = 5
3.9 x 10 ^-5 is the answer. 0.000039 in scientific notation is 3.9 x 10^-5
The answer is -1/5. i typed it into google lol
Answer:
e. a point estimate
Step-by-step explanation:
When an estimate for the unknown population parameter is expressed by a single value it is called a point estimate.
Example : If we wish to find the height of a very large group of students on the basis of a sample and we find it to be 64 inches. 64 inches is the point estimate.
<em>Similarly the value given is the point estimate.</em>
Point estimate of the population parameter provides as an estimate a single value calculated from the sample that is likely to be close in value to the unknown parameter. It is to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.
