A soft drink machine outputs a mean of 27 ounces per cup. the machine's output is normally distributed with a standard deviation
kkurt [141]
The probability will be the area under the normal distribution N(27,3^2) from 24 to 32.

We normalize these so we can use the standard normal distribution

z_1 = \dfrac{24 - 27}{3} = -1

z_2 = \dfrac{32-27}{3}=\dfrac 5 3

Typically we'd just use a computer to tell us the integral of the standard normal from -1 to 5/3.  In the old days we'd use the z table.  It tells us the normal integral from 0 to positive z.

We know the integral of the Gaussian from -1 to 1 standard deviation is 68%; from the z table we see the probability from 0 to 1 is half that, <span>0.34134.  That will also be the integral from -1 to 0. 

The z table says the integral from 0 to 5/3, 1.67, is </span><span>0.45254.

So our total probability, integral from -1 to 5/3, is

 </span>p =0.34134+0.45254=0.79388

That's really from z=-1 to z=+1.67 so likely a bit off in the last couple digits.

Question 2(Multiple Choice Worth 5 points)
serg [7]

Answer:

#1 d= 49t

Step-by-step explanation:

#2 Since the greatest value of n is 9, it means that the value of n is less than or equal to 9. But the values of n cannot be greater than 9. So, we will be using the sign of less than or equal to in the inequality. Thus, (D) is the correct option.

#3 is (29)

#4 is n=15

#5 is y = 7x

#6 is y=7x

Round to the nearest tenth: 0.848076<br> 0<br> 0.9<br> 0.84<br> 0.8
adell [148]
0.848076
   ^ This is the tenths place.

The number after it is 4, which is less than 5. So we round down to 0.8.

The equation of line AB is y = 5x + 1. Write an equation of a line parallel to line AB in slope-intercept form that contains poi
castortr0y [4]
Y = 5x + 1....the slope here is 5...a parallel line will have the same slope.

y = mx + b
slope(m) = 5
(4,5)....x = 4 and y = 5
now we sub and find b, the y int
5 = 5(4) + b
5 = 20 +b
5 - 20 = b
-15 = b

so ur parallel line is : y = 5x - 15
