The answer is 12.6
419 is 420 because we are estimating so find 1% of 420 which is 4.2 then multiply 4.2×3 to get 12.6
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%.

Answer
im going to have to say the answer is B
Step-by-step explanation:
First look at it nothing can be above 0 so if the graph has 1 before 0 its wrong then u have completed one step of the equation.
Remember
and
if
where x=x then m=n
so
so
m+n=-6
so test the options
first one works
2nd ones doesn't
3rd one doesn't
4th one doesnt'
answer is first option, m=3 and n=-9
