Answer:
No.
Step-by-step explanation:
No because if we substitute the given values into the equation they do not fit:
y = 7x
x = 1 and y = 4:
Left side = 4
right side = 7*1 = 7.
Answer: 1692
Step-by-step explanation:
Formula to find the sample size :
Given : Confidence level :
⇒ significance level =
z-value for 90% confidence interval (using z-table)=
Prior estimate of the population proportion (p) of customers who keep up with regular vehicle maintenance is unknown.
Let we take p= 0.5
Margin of error : E= 2%=0.02
Now, the required sample size will be :
Simplify , we get
Hence, the required sample size = 1692
Answer:
?=78
Step-by-step explanation:
You plug in -3 for x. -3^2 is 9. Multiply 2*9 and subtract 5 from that. Get 13. Multiply 6 and 13 to get 78
Diving and then subtract finally multiple
If it were always finding the opposite of the number, then
we would have to say that the absolute value of 7 is -7 .
We know that's not true.
It's better to tell Angelique that finding the absolute value
of a number means just looking at the size of the number
and ignoring its sign completely.
