Hope this helps but I this helps but I think the answer is D if not then try B
Answer:
D
Step-by-step explanation:
I usually use a z-score table, but you can do this with a calculator.
If we go to a z-score table, we first look up the first two digits (in this case, 2.8) in the far left column. Then we find the hundredths digit in the top row (0.07). Where they intersect is P(z < 2.87).
P(z < 2.87) = 0.9979
Answer D.
Answer:
1. 32$
2. 8 people
Step-by-step explanation:
1.65-25=40-8=32
2.100-50=50-6×8=is 2 and u can't-6 anymore
Answer:
DIVIDING COMPLEX NUMBERS
<em>Dividing complex numbers is a little more complicated than addition, subtraction, and multiplication of complex numbers because it is difficult to divide a number by an imaginary number. For dividing complex numbers, we need to find a term by which we can multiply the numerator and the denominator that will eliminate the imaginary part of the denominator so that we end up with a real number in the </em><em>DENOMINATOR</em>
Answer:
Step-by-step explanation:
7-4=3
now let's change the denominator by finding the lcd (lowest common denominator)
<em>factors of 3:</em> 3, 6, 9, 12...
<em>factors of 6:</em> 6, 12, 18, 24...
both 3 and 6 has 6 as their lcd
3 x 2= 6
1/6 -4/6= -3/6
REDUCE
-1/2
3-1/2
2 1/2
