Answer:
0.98 also 98%
Step-by-step explanation:
In this question we have the Lower limit to be 0.16
We have the Upper limit to be 0.24
Such that (0.16+0.24)/2 = 0.40/2 = 0.20
Standard deviation= √(0.2x0.8/545) this gives 0.017134
Next we get margin of error
Margin of error = 0.24-0.20 = 0.04
Z multiplied by sd =0.04
Such that
Z = 0.04/0.017134 =2.33
On this z score, the Corresponding level of confidence is 0.98
Which is 98%
Options would be nice, but the dotted line equation appears to be:
log(x) + 5,
A transformation of
log(x) , which is the equation for the solid line.
Answer:
956= 9/56
125= 1/25
Step-by-step explanation:
Answer:
28.27 in²
Step-by-step explanation:
The equation for the area of a circle is A = π
. However, we got the diameter.
diameter = 2(radius), so:
A = 
πd².
A = 1/4 * π * 6² ≈ 28.27433
Answer:
Step-by-step explanation:
The odd numbers.
Suppose you have 31 and 27 when you add these two together, you get 58 which is not an odd number.
If you need a more mathematical proof, you could do it this way.
2x+1
2x is even. Anything multiplied by 2 is even. When you add 1 you get an odd number
So continue on
2y + 1 is the other number.
2x + 1 + 2y + 1 = 2(x + y) + 2
2 (x + y ) is even. When you add 2 to it, nothing changes. The result is still even.
