Answer:
The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of
.
An experimenter flips a coin 100 times and gets 59 heads.
This means that 
98% confidence level
So
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).
Answer:
1(a) = 10
1(b) = 9
1(c) = 12
2(a) = 8
2(b) = 10
2(c) = 1
Step-by-step explanation:
1(a) = 22 - 2.6
= 22 - 12 = 10
1(b) = 6 - 1/4 . 16 + 21 / 3
= 6 - 16/4 + 7
= 6 - 4 + 7
= 9
1(c) = (8-5). (5-3)^2
= 3*2^2
= 3*4
= 12
2(a) = 4(x-2)/(x-1) when x = 0
= 4(0-2)/ (0-1)
= 4*-2/-1
= -8 / -1
= 8
2(b) = (-3x^2 + 4) / 4 when x = -2
= (6^2 + 4) / 4
= (36 + 4) / 4
= 40 / 4 = 10
2(c) = [-2x/4 + 4*(x-1)] / x^2 - 1 when x = 2
= (-1 + 4 * 1) / 4 - 1
= 3 / 3
= 1
The answer is none of the above for you can get the answer by multiplying the base x height. This answer is 388,800, and none of the given answers above come close to being the correct answer so again, the answer is E. None of the Above
Forty three million, eighty thousand, seven hundred
1.Since 5 is less than 8, borrow 1 from the next column to make 15.
2.Calculate 15 - 8, which is 7.
3.Calculate 3 - 3, which is 0.
4.Since 2 is less than 5, borrow 1 from the next column to make 12.
5.Calculate 12 - 5, which is 7.
6..<span>Calculate 9 - 2, which is 7.</span>
7.<span>Therefore, 102.45 - 25.38 = 77.07.</span>
