Answer: d. 37.2 mi
Because to find the average, you add the numbers together then you divided the amount of numbers added together.
Like: 36+38.4 = 74.4/2 = 37.2
The answer is <span>a.−4x^2 − 3x + 2

the quantity 8 times x to the third power plus 6 times x to the 2nd power minus 4 times x all over negative 2 times x is:
Answer:
24m²
Step-by-step explanation:
To find the area of a rectangle, we use the formula A = l * w or Area = length * width.
We know that our length is 2 meters and our width is 12 meters so we can plug these values into the formula to get our answer.
A = 2 * 12 = 24
Remember that area is measured in "square" units and must be raised to the 2nd power.
A = 24m²
Answer:
DF = 458
Step-by-step explanation:
In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.
The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;
DF = n - 1
where n is the sample size
Given n is 459, DF = 459 - 1 = 458
Therefore, DF = 458
Answer:
= 186 F
136 F is taken as the steam point
-50 F is taken as the ice point
∴ difference = steam point - ice point
= 136- (-50)
= 186F
