I believe it’s B
Your trying to find the area of the triangle of the two numbers of that makes any kind of sense
Answer:

Step-by-step explanation:
The axis of symmetry can be calculated using the formula:

First we must determine a and b from the quadratic:
. This is in standard form, with the highest power first in descending order.
Standard form is also: 
If we compare this to the quadratic given, we can conclude that:

Substitute the values for a and b into the formula.

Multiply in the denominator.

Divide.

This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
Answer:
The correct option is a
Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
The sample size is n = 9
The null hypothesis is 
The alternative hypothesis is 
The level of significance is 
The sample mean is 
Generally the test statistics is mathematically represented as

=> 
=> 
From the z table the area under the normal curve to the right corresponding to 1.2 is

Generally the p-value is mathematically represented as

=> 
=> 
From the value obtained w can see that
hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is there is not enough evidence to support the claim
Started out with 32/32. They ate 18/32, 32-18=14; 14/32. To simplify, 7/16 was left.
