Step-by-step explanation:
Answer:
a. 7 and 4
b. 28
Step-by-step explanation:
7 minus 4 is 3
7 plus 4 is 11
7 times 4 is 28
Answer:
A
Step-by-step explanation:
The appropriate inference procedure in this case is a one-sample t test for a mean. The test statistic for this test is
.
let those numbers be x and y
According to your question
x + y = -7
x - y =14
adding both equations
2x = 7
or x = 7/2
substitute value of x in either equation
y = -21/2
So,
x= 7/2
y=-21/2

The value of x = 24
Since there’s 4 even sides, add up the number you know. So, 4 • 4 = 16. Then subtract 16 from the perimeter of 112 to get 96. Lastly, divide that number by 4 to find what x equals. And, 96 / 4 = 24.
Hope this helps!
