Its -2 three times, making it -6
If you multiply a positive and negative it is always negative
C is the answer cause 9 is the common factor
Answer:
The mean temperature is O
Step-by-step explanation:
The probability illustrated shows that the
percent of cookies would have between 13.8 and 24.2 chips is 95.44%.
<h3>How to calculate the probability?</h3>
It is important to note that the requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.
This will be illustrated thus:
Z value for 13.8, z =(13.8-19)/2.6 =-2
Z value for 24.2, z =(24.2-19)/2.6 = 2
P( 13.8<x<24.2) =P(-2<z<2)
=P( z <2 –P(z < -2)
=0.9772 -0.0228
=0.9544
= 95.44%
The percent is 95.44%.
