Answer:
Step-by-step explanation:
According to the given information, we have
Sample size : n= 50
Since population standard deviation is unknown, so we use t-test.
Critical value for 95 percent confidence interval :
Confidence interval :
Required 95% confidence interval :
Wouldn't that be
6 remainder 150?
So this is our table:
-----------------
x-values | a b c d e f |
-----------------
y-values | g h i j k l |
-----------------
You can know that the values in the table are proportional if:
Hope that helps :)
Answer:
37.7
Step-by-step explanation:
<h2><u>circumference of a circle:</u></h2>
Formula = 2πr
r is the radius
diameter = 2* radius
hence radius = 12/2
radius = 6 yards
2*π*6 = 37.6991
to 3sf
<h3><u>circle circumference is 37.7</u></h3>
5r + 8 < 63
5r < 63 - 8
5r < 55
r < 55
{r | r < 11}
