The answer is Letter D - 84%
68% of the data is within +/- 1 SD from the mean = 59 to 7195% of the data is within +/- 2 SDs from the mean = 53 to 7799.7% of the data is within +/- 3 SDs from the mean = 47 to 83
The whole 68% (59 - 71) scored below 71. Since the data are evenly distributed, we'll get the 32% (100 - 68) outside the range of 68% and divide it by 2 and add the quotient to the original 68% so that we'll get the total data below 71.
100 - 68 = 32
32 / 2 = 16
16 + 68 = 84
Answer:
what is the question
Step-by-step explanation:
Answer:
p=1/8 q=3/4
Step-by-step explanation:
-2p+7q=5
-6p+35q=51/2
cancel out a variable
(-5)(-2p+7q=5)
-6p+35q=51/2
10p-35q=-25
-6p+35q=51/2 =
4p=1/2
4p/4=1/2 /4
p=1/8
substitute p=1/8 into one of the equation to find q
-2p+7q=5
-2(1/8)+7q=5
-1/4+7q=5
7q=5+1/4
7q=21/4
q= 21/4 /7
q=3/4
Answer:
4
Step-by-step explanation:
Use PEDMAS
18 - 6(2+4-1+2) ÷ 3
18 - 6(6 - 1 + 2) ÷ 3
18 - 6(5 + 2) ÷ 3
18 - 6(7) ÷ 3
18 - 42 ÷ 3
18 - 14
4
Hope this helps!
Step-by-step explanation:
So the way you do this is if it says 'Find AC' and on the angle you see different letters connect then on the lines and name the angle
More that 90°= Obtuse
90° angle= 90° angle
Less than a 90° angle= isosolines angle
