Negative. A negative number times a positive number is equal to a negative number. X multiplied by Y is a positive.
Answer:
b) 7×8
c) 4×14
d) 2×28
Step-by-step explanation:
A factor pair of a number is a pair of numbers that, when multiplied will result in the given number.
The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, and 56.
The factor pairs are:
Out of the options, only Option A is not a factor pair.
It's C the missing side is 9 units long so since cosine is adjacent divided by hypotenuse it would be 9/41
The answer is: [C]: "Astrologers do not use the scientific method."

Choice [D] is incorrect. Astrologers may or may not go to college; and whether or not they do or do not is irrelevant as regard to whether to they are considered "scientists".

Answer:
Step-by-step explanation:
We can calculate this confidence interval using the population proportion calculation. To do this we must find p' and q'
Where p' = 14/100= 0.14 (no of left handed sample promotion)
q' = 1-p' = 1-0.14= 0.86
Since the requested confidence level is CL = 0.98, then α = 1 – CL = 1 – 0.98 = 0.02/2= 0.01, z (0.01) = 2.326
Using p' - z alpha √(p'q'/n) for the lower interval - 0.14-2.326√(0.14*0.86/100)
= -2.186√0.00325
= -2.186*0.057
= 12.46%
Using p' + z alpha √(p'q'/n)
0.14+2.326√(0.14*0.86/100)
= 0.466*0.057
= 26.5%
Thus we estimate with 98% confidence that between 12% and 27% of all Americans are left handed.
