Suppose flights on standard routes between two given cities use on average 3,087 gallons of kerosene with standard deviation of

Radda [10]

Answer:

15.866%

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 3,282 gallons of kerosene

μ is the population mean = 3,087 gallons of kerosene

σ is the population standard deviation = 195 gallons

For x > 3282 gallons

z = 3282 - 3087/195

z = 1

Probability value from Z-Table:

P(x<3282) = 0.84134

P(x>3282) = 1 - P(x<3282) = 0.15866

Converting to percentage

0.15866 × 100 = 15.866%

The percent of flights on these particular routes that will burn more than 3,282 gallons of kerosene is 15.866%

Answer:

3, <u>36</u>, 108

Step-by-step explanation:

Can't tell you if that is definitely correct, but I tried. All I did was try to figure out the common ratio for each sequence.

E.g. 3x36 = 108.

A landscaper is designing a flower garden in the shape of a trapezoid. She wants the length of the shorter base to be 3 yards gr

gizmo_the_mogwai [7]

Correct Answer:
Option A. 17.1 Yards

Solution:
Let the height of trapezium is x yards. According to the given data, we can express the lengths of bases in terms of height.

The short base is 3 yards greater than the height, so measure of short base will be (x+3) yards.

The longer base is 5 yards greater than the height, so measure of longer base will be (x+5) yards.

Area of trapezium is given to be 360 square yards.

Area of trapezium = 0.5 x (Height) x (Sum of Bases)

Using the values, we get:

$360=0.5(x)(x+3+x+5) \\ \\ 
720=x(2x+8) \\ \\ 
2 x^{2} +8x-720=0 \\ \\ 
2( x^{2} +4x-360)=0 \\ \\ 
 x^{2} +4x-360=0 \\ \\ 
x= \frac{-4+- \sqrt{16-4(1)(-360)} }{2} \\ \\ 
x= \frac{-4+- \sqrt{1456} }{2} \\ \\ 
x = 17.1 , -21.1$

Since the height cannot have a negative value, we conclude that the height of trapezium rounded to nearest tenth of a yard will be 17.1 yards.
