Answer:
Step-by-step explanation:
Given that Heights of 10-year-olds, regardless of gender, closely follow a normal distribution with a mean of 55 inches and a standard deviation of 6 inches.
If X is height then X is N(55,6)
Z score would be 

b) 
c) Tallest 10% z = 1.28
X score =
inches
d)
i.e. 16.37% cannot go on this ride.
Answer: 135 ft³
Step-by-step explanation:
Volume, when dealing with a rectangular prism, is L * W * H
-> L * W can simplify to the base, as it does in the problem given to us.
V = (L * W) * H
V = B * H
V = 15 * 9
V = 135 ft³
The rectangular prism has a volume of 135 ft³.
Answer:
y = -
x + 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x + 1 ← is in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (- 5, 11) into the partial equation
11 =
+ c ⇒ c = 11 -
= 
y = -
x +
← equation of perpendicular line
Answer:
It costs Lauren 14 dollars to ride 8 miles
Step-by-step explanation:
The equation for the price of the taxi ride is
y= 1.5x+2
where y is the price, and x is the number of miles driven. Lauren needs to ride 8 miles, so the price of her taxi ride is
y= 1.5*8 +2 =12+2=14
