Answer:

1 is leading coefficient. last option is correct

Explanation:

We have been given the quadratic function x^{2}-8x-4

We know that leading coefficient is the coefficient of the variable having highest exponent.

So, in order to state the leading coefficient we first of all find the highest exponent of the given function.

Clearly, the given function is quadratic and hence, the highest exponent is 2.

The coefficient of the variable of highest exponent is 1.

Therefore the leading coefficient is 1. last option is correct

Answer:

\text{Null hypothesis}: H_0:\mu=90\\\\\text{Alternative Hypothesis}:\mu\neq 90

Step-by-step explanation:

Given claim : From the time shoots are planted 90 days on average are required to obtain the first berry.

. The sample mean is 92.3 days. The corporation wants to know if the mean number of days is different from the 90 days claimed.

As we know that the null hypotheses shows there is no statistical difference between the groups but the alternative hypothesis is opposite to it, it shows there is difference.

Thus , the correct hypotheses will be :-

\text{Null hypothesis}: H_0:\mu=90\\\\\text{Alternative Hypothesis}:\mu\neq 90
