Answer: 175V
Step-by-step explanation:
V112+V63=112v+63V
Add them together because the terms are like terms. Therfore, 112V+63V=175V
Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000
So if increase in length = x we have
(x + 120)(x + 80) = 14,000
x^2 + 200x + 9600 - 14000 = 0
x^2 + 200x - 4400 = 0
x = 20 feet answer
What table.
If it is a normal table or a wooden table. The marble ones are cool but I prefer the wood. btw this is just filler text so I could ask if you would link the table.
Answer:
Vertex : (-2,1)
other points : (0,5) & (-4,5)
Step-by-step explanation:
The value of alpha is 0.26, assuming a confidence level of 74%.
<h3>What is the margin of error?</h3>
The significance level α is the probability of making the wrong decision when the null hypothesis is true.
Alpha levels which is also called as significance levels are used in hypothesis tests.
Given
When finding the margin of error for the mean of a normally distributed population from a sample.
The confidence interval = 74% = 0.74.
The value of the alpha is given by;

Substitute all the values in the formula

Hence, the value of alpha is 0.26, assuming a confidence level of 74%.
