8 0
Xy= 120
x= 7+y

(7+y)(y) = 120
y^2 + 7y - 120 = 0
(y + 15) (y - 8) = 0

Since we are finding two positive numbers,
If y= 8 then x= 15

The two numbers are 8 and 15

Hey can you please help me posted picture of question:)

We have the following equation:
 2x2-3x + 1
 Using resolver we have:
 x = (- b +/- root (b2-4ac)) / (2a)
 Substituting values we have:
 x = (- (- 3) +/- root ((- 3) 2-4 (2) (1))) / (2 (2))
 Rewriting:
 x = (3 +/- root (9-8)) / (4)
 x = (3 +/- root (1)) / (4)
 b2-4ac = 1> 0
 root(b2-4ac) = 1 < 3
 Answer:
 
Two positive real solutions

the average woman's height is 65 inches with a standard deviation of 3.5 inches. what proportion of women are shorter than 62inc
MrRa [10]

Answer:

19.77%

Step-by-step explanation:

Given

Mean= μ=65 inches

SD= σ=3.5 inches

We have to find the proportion of women whose height is less than 62 inches.

For that we have to calculate z-score for the given value first. The z-score of a value tells us that how many standard deviations the value is far from mean. The area to the left of the z-score gives the proportion of data that is less than the z-score value and the area to the right gives the proportion.

So,

z-score of 62=  (x-μ )/σ

=(62-65)/3.5

=  (-3)/3.5

z-score of 62= -0.8571

To find the area to the left of the z-score, the z-score table is used which is easily available on the internet.

The area to the left of the z-score is 1.97662.

To find the proportion/percentage of women whose height is less than 62, the area has to be multiplied by 100.

Percentage of women whose height is less than 62 inches=0.197662*100

=19.77%
