ok i know the answer 1+1=2
Answer:
an = 9n -16
Step-by-step explanation:
First find the common difference, d
Take the second term and subtract the first
2 - (-7) = 2+7 = 9
We are adding 9 each time
Check 2+9 =11, check 11+9 = 20 check
The first term in the sequence is a1 so a1 =-7
an = a1 + d(n-1)
an = -7 + 9(n-1)
Distribute
an = -7 +9n-9
Combine like terms
an = 9n -16
Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level
No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05.
The correlation coefficient differs from zero when the p-value is less than 0.05.
Answer:
f (
x
) −
1 =
(
1/
4 x
) −
2.
Step-by-step explanation:
For inverse function, the x and y interchanges and then make y the subject again of the equation. See the working out below:
f (
x
) = 4
x + 8
f (
x
) = y
y = 4
x + 8
x = 4
y +
8 ----- interchanging y and x
Now make y the subject of the equation:
x = 4
y + 8
−
4
y = -
x + 8
y = (
−
1/
4 )
. − x
+ (
−
1/
4 ) .8
y = (
1/
4 x
) −
2
So the inverse function is:
f (x) −
1 = (
1/
4 x
) −
2
Answer:
circumference is 50.24cm
Step-by-step explanation:
π
= 200.96
r = 
= 
=8
Circumference = 2πr = 2 x.3.14.x 8 = 50.24
