Answer:
70%
Step-by-step explanation:
since 7/10 is 0.7 as a decimal
you can then turn it into a percent by moving the decimal point two spots to the right
70 --> 70%
another way to do it is, to add zeros on both the numerator and denominator
then it is valued at 70/100
a percent is a number over 100
70 ---> 70%
your answer is 70%
hope this helps

= ------- / ------------------
a -5 (a - 3)(a - 5)
a+2 (a - 3)(a - 5)
= ------- * ------------------
a -5 a +1
(a+2)(a - 3)
= ----------------
a +1
a NOT equal 5 and -1

Answer:
A. 0.0049
B. Yes
Step-by-step explanation:
Sample proportion = 0.64
N = 1000
Population proportion = 0.60
We solve for standard deviation
= √p(1-p)/n
= √0.60(1-0.60)/1000
= √0.60x0.40/1000
= √0.00024
= 0.0155
A.
The probability of sample >=0.64
Z>=0.64-0.60/0.0155
Z >= 0.04/0.0155
So z >= 2.5806
Using excel this equal to 0.0049
0.0049 is probability of sample proportion being 0.64 at least.
