Angle D is 60° because it is a supplementary angle, meaning 180 (straight line) - 120 (angle A) = 60°
Answer:
7
Step-by-step explanation:
Because 7+3= 10, Please tell me if my answer is wrong
Answer:
C. mean: 6.4 and standard deviation: 2.31862028
Step-by-step explanation:
We are given
n=40
p=0.16
q= 1-p = 0.84
mean = np = 40*0.16 = 6.4
standard deviation =
= 
sd = 2.31862028
You are looking at around 81.5% i assume by shifting the standard deviation by the same amount on both sides the % will not change
i split the normal distribution curve into 8 pieces
.15 +2.35+13.5+34+34+13.5+2.35+.15 34+34+13.5=81.5%
the ones bolded are the sections that u r dealing with
now the standard deviation is only 4400 so these numbers are going to be skewed off to the right a bit however bcus both sides are skewed evenly i believe they balance each other out
im not completely certain of this but still i hope i helped if so give me a brainliest answer i need a few more to move up a rank -J (:
Answer:
Description:
Distribute 2j to (j+3).
Rewrite the summation as the sum of two individual summations.
Evaluate each summation using properties or formulas from the lesson.
The lower index is 1, so any properties can be used.
The sum is 5,494,000.
