Answer: - 235
<u>Step-by-step explanation:</u>
f(x) = -3x² + 13x + 3
f(-7) = -3(-7)² + 13(-7) + 3
= -3(49) - 91 + 3
= -147 - 88
= -235
Answer:
Step-by-step explanation:
we have
Solve for x
Adds 6 both sides
Divide by 3 both sides
square root both sides
Remember that
so
simplify
Using translation concepts, it is found that the table of values for function g(x) is given as follows:
x 0 1 2 3
g(x) -7 0 5 8
<h3>What happens when a function is reflected across the x-axis?</h3>
When a function is reflected across the x-axis, all it's values are multiplied by -1.
Hence, considering the values of f(x) given in the problem, the table of values for function g(x) is given as follows:
x 0 1 2 3
g(x) -7 0 5 8

Answer:
The requirements for the hypothesis test are not met
Step-by-step explanation:
We have the following information from the statement:
sample size = n = 60
Probability = p = 13% = 0.13
Now, we calculate the multiplication of this which would be:
n * p = 60 * (0.13) = 7.8 which is less than 10
Therefore the requirements for the hypothesis test are not met, since the multiplication of n by p would have to be greater than 10 for it to be met, but this is not the case.
Answer:Julie's average score was 76
Step-by-step explanation:
The formula for Average or mean is expressed as
Average = sum of terms / total number of terms.
Julie's first three test scores in biology were 65, 90 and 73.
The sum of the scores would be
65 + 90 + 73 = 228
The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,
Average = 228/3 = 76
