Answer:
2.275%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)SD
here, x = 70.5
mean = 65.5
SD = 2.5
Substituting these values;
z = (70.5-65.5)/2.5
= 5/2.5 = 2
So we want to calculate the probability that;
P( z> 2)
We check the standard normal distribution table for this
That will be
0.02275
In percentage, this is 2.275 %
All you have to do is multiply 4 × 6 to get your answer. So, 4 × 6 = 24, and considering we can't leave the variable out, we have to put it with our answer. Our answer is then 24x. Hint: Parentheses mean multiplication.
Answer:
m= -3
Step-by-step explanation:
slope intercept formula
(y2-y1)/ (x2-x1)
-6-3= -9
-2-1=-3
-9/3 =-3
Answer:
24 hours/1 day
Step-by-step explanation:
hours per day is a rate which can be expressed in the form of a fraction. since there are 24 hours in one day you know that as a fraction, they are equal to 1. you can then put 24hours/1day.
