Answer: 99 insects altogether.
Step-by-step explanation:
Adding two numbers add a time is easiest, rather than adding all four numbers together.
First, add 37 + 39 =. 76
add 12 to that sum, which equals 88.
76+12=88
to that sum, add the final number, 11.
88+11=99
so there are 99 bugs altogether.
Answer:
The probability that none will have high blood pressure is 0.0281
Step-by-step explanation:
The correct question is as follows;
Twenty percent of Americans ages 25 to 74 have high blood pressure. If 16 randomly selected Americans ages 25 to 74 are selected, find each probablility. a. None will have high blood pressure
This is a binomial problem. We shall solve in that line
The probability of success is 20% or 0.2 [(Americans ages 25 to 74 have high blood pressure)] p = 0.2
The probability of failure q is thus 1-p = 1-0.2 = 0.8
The probability of none is thus;
P(X= 0) = 16C0 p^0 q^16
= 16C0 * 0.2^0 * 0.8^16 = 0.0281
Answer:
-10
Step-by-step explanation:
-7+(-3)= -7-3
= -(7+3)
= -10

Answer:
Range is 18.
Step-by-step explanation:
Range can be calculated by subtracting the smallest value of the data set from the largest value of the data set.
The values are:
13, 17, 18, 15, 12, 21, 10, 6, 8, 11, 3
Largest Value in this data set: 21
Smallest Value in this data set: 3
Range = Largest Value - Smallest Value
Range = 21 - 3
Range = 18
