The top question should be greater than or equal to. not just greater than. so the circle should be closed. and as for the direction, it should be a closed circle on 13.50 pointing towards the right
So before i give u the answer i will explain
step 1- Underline key info( 40PIZZA and 120 PEOPLE)
step 2- do 140\40 which then u will get 3( we do this cause we wanna find out how many times this number can go into 120)
step 3- ur answer is 3 pizza per person
Answer:
Step-by-step explanation:
slope=(0-3)/(3-0)=-3/3=-1
y intercept=3
eq. of line is y=-x+3
Answer:
99.89% of students scored below 95 points.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What percent of students scored below 95 points?
This is the pvalue of Z when X = 95. So



has a pvalue of 0.9989.
99.89% of students scored below 95 points.
