20 I apologize if this is wrong
21 + p = 44
Subtract 21 from both sides;
21 + p - 21 = 44 - 21
p = 23
Answer:
x > −3
Step-by-step explanation:
Let's solve your inequality step-by-step.
3(x + 2) > x
Step 1: Simplify both sides of the inequality.
3x + 6 > x
Step 2: Subtract x from both sides.
3x + 6 − x > x − x
2x + 6 > 0
Step 3: Subtract 6 from both sides.
2x + 6 − 6 > 0 − 6
2x > −6
Step 4: Divide both sides by 2.
2x / 2 > −6 / 2
x > −3
Answer:
x > −3
Hope this helps :)
How much work is done in an hour by each:
s = 1/6 of the yard in one hourb = 1/10 of the yard in an hour
working together they can do:
1/6 + 1/10 in an hour; or 16/60; we can invert this number to determine how long it takes to finish the yard
60/16 hours
=3 hours and 45 minutes
Answer:
And the 96% confidence is given by (110.06; 117.34)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=9.1 represent the sample standard deviation
n=29 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence is 0.96 or 96%, the significance is 
and 
, and the critical value would be 
Replacing the info we got:
And the 96% confidence is given by (110.06; 117.34)
