Answer:
Step-by-step explanation:
3244314 x 2 = 6,488,628
6,488,628 + 3242 = 6,491,870
The multiplication of 232 x 5 = 1,160
Answer:
B
Step-by-step explanation:
- A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
- For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
- We can calculate P value
Confidence Interval = p ± z
Answer:
0.25
Step-by-step explanation:
The answer that goes in the blank is: 3
Note: The "pi" portion is already taken care of, so there's no need to enter it in the box.

Explanation:
The distance around the entire circle is found by the circumference formula
C = 2*pi*r
where r is the radius.
In this case, r = 27, so,
C = 2*pi*r
C = 2*pi*27
C = 2*27*pi
C = 54*pi
The full distance around the circle is exactly 54pi units
We only want a small portion of it. We only want 20/360 = 2/36 = 1/18 of that distance
So multiply (1/18) by 54pi and we get...
(1/18)*(54pi) = (54/18)*pi = 3pi
So the length along the curve from A to B (or vice versa) is exactly 3pi units.
Answer:
y=5x+350
If Elena spent a total of $1000, she made 130 shirts.
Step-by-step explanation:
Let x be the number of T-shirts. Let y be the amount of money spent.
1000=5x+350
5x=650
x=130
