Hey there :)
Let us translate each one separately
{ Using w for unknown }
The
difference of a number divided by 3 and 5
is 2
'is' is the key-word, meaning you apply the = sign
Difference is subtraction
→ a number divided by 3 - 5 = 2
This is your equation: →
Solving for wTake 5 to the other side
[ When you see subtraction you do addition on the opposite side ]
→

Take 3 to the other side
[ When you see division you do multiplication on the opposite side ]
w = 3 x 7
w = 21
The correct answer is A.
When any part of the fraction is negative, the whole thing is negative.
This is because a positive divided by a negative is a negative and vise versa.
B.
(9)^2 + (12)^2 = 225
Square root of 225 gives you 15 !!
We found it by applying Pythagorean’s theorem which only applies to right triangles.
Hope it help !!
There is a total of 12 months.....and 1 stranger
so the probability of guessing the birth month of a stranger is 1/12
Answer:
0.099 is the probability of a woman between the ages of 20 to 29 having a VO2MAX score of greater than 45 ml/min/kg.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 36 ml/min/kg
Standard Deviation, σ = 7 ml/min/kg
We assume that the distribution of aerobic power is a bell shaped distribution that is a normal distribution.
Formula:
a) P(woman between the ages of 20 to 29 having a VO2MAX score of greater than 45 ml/min/kg.)
P(x > 45)
Calculation the value from standard normal z table, we have,

0.099 is the probability of a woman between the ages of 20 to 29 having a VO2MAX score of greater than 45 ml/min/kg.
