Answer:
Step-by-step explanation:
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. Men have hip breadths that are normally distributed with a mean of 14.4 inches and a standard deviation of 1 inch. find P98. I really don't understand, help needed please.
-----------------------
Find the z-value with a left tail of 0.98
invNorm(0.98) = 2.0537
-----
Find the corresponding x-value using x = zs+u
----
x = 2.0537*1+14.4
---
x = 16.45 inches

Answer:
x = 6 and the +4x is wrong
Step-by-step explanation:
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
+4x +4x <--( <u>This part is wrong</u> )
10x + 4 = 16
-4 -4
10x = 12
10 10
x = 1.2
Correct steps
2x + 4x + 4 = 4(x + 4)
6x + 4 = 4x + 16
-4x -4x
2x + 4 = 16
-4 -4
2x = 12
2 2
x = 6

Answer:
x=-19
y=55
Step-by-step explanation:
y=-3x-2.
5x+2y=15
substitute y into 5x+2y =15
5x +2 (-3x-2) = 15
distribute
5x -6x-4 = 15
combine like terms
-x-4 =15
add 4 to each side
-x-4+4 = 15+4
-x=19
multiply by -1
x = -19
now lets find y
y= -3x-2
y = -3(-19) -2
y = 57-2
y =55
