Answer:
d) ÷
Step-by-step explanation:
120 ÷ 3/11 = 440
A:
1 day = 1/8 of work
B:
1 day = 1/24 of the work
Together:
1 day = A + B = 1/8 + 1/24 = 4/24 = 1/6
1 day = 1/6 of work
1/6 x 6 of work = 1 x 6 days
work = 6 days
Answer:
In the photos
Step-by-step explanation:
First, create your trees (following instructions on the photo you attached). Then, circle the prime numbers in each tree you made. If the prime number shows up once put that number once on your prime factorization. If the prime number appears multiple times, put the number down and have an exponent (the exponent is determined by how many times that number appears).

Answer:
535 students passed and 107 students failed
Step-by-step explanation:
Create a system of equations where p is the number of students who passed and f is the number of students who failed:
p + f = 642
p = 5f
Solve by substitution by plugging in 5f as p into the first equation, then solving for f:
p + f = 642
5f + f = 642
6f = 642
f = 107
So, 107 students failed.
Find how many students passed by multiplying this by 5:
107(5)
= 535
535 students passed and 107 students failed.
Answer:
the approximate probability that the total weight of the passengers exceeds 4668 pounds is 0.0089
Step-by-step explanation:
Using the central limit Theorem
z = (x - u )/Q÷ sqrt n
Where z is the z-score
x is the average weight = 4668/22 = 212.2
u is the passengers average = 194 pounds
Q is standard deviation = 36 pounds
Therefore
z= (212.2 - 194) / 36 ÷ sqrt22
= 18.2/ 36÷ 4.69
= 18.2/7.68
z=2.3698 aprx 2.37
Find the value of 2.37 z-score on the z-table to determine the approximate probability
P(z>2.37) = 0.0089 (from the z-table)
