The area of the triangle given in the figure is 6 square units.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

We need to find the area of triangle.

Area of triangle is 1/2 × Base × Height

The length of base is 6 units.

The length of height is 2 units.

Now let us plug in the value of base and height into the given formula of triangle.

Area of triangle =1/2×2×6

=6 square units

Hence, the area of the triangle given in the figure is 6 square units.

Suppose management could improve the process by reducing the mean time required for an oil change (but keeping the standard deviation the same). How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average

Answers

This question is incomplete, the complete question is;

The owners of Spiffy Lube want to offer their customers a 10-minute guarantee on their standard oil change service. If the oil change takes longer than 10 minutes to complete, the customers is given a coupon for a free oil change at the next visit. Based on past history, the owners believe that the timer required to complete an oil change has a normal distribution with a mean of 8.6 minutes and a standard deviation of 1.2 minutes.

Suppose management could improve the process by reducing the mean time required for an oil change (but keeping the standard deviation the same). How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average

Answer:

Required change in the mean service time is 7.8988

Step-by-step explanation:

Given the data in the question;

How much change in the mean service time would be required to allow for a 10-minute guarantee that gives a coupon to no more than 1 out of every 25 customers on average

let mean = μ

p( x > 10 ) ≤ (1/25)

p( x > 10 ) ≤ 0.4

p( x-μ / 1.2  > 10-μ / 1.2 ) ≤ 0.4

(10-μ / 1.2 ) ≤ 0.4

(10-μ / 1.2 ) ≥ [tex]q_{norm}[/tex] ( 0.96 )

(10-μ / 1.2 ≥ 1.751

10-μ  = ≥ 1.751 × 1.2

10-μ  ≤ 2.1012

μ ≤ 10 - 2.1012

μ ≤ 7.8988

Therefore, required change in the mean service time is 7.8988

Answer:

14.4 ft

Step-by-step explanation:

The triangles formed by both ladders are similar to each other. Therefore, each corresponding sides will be proportional.

Thus, x + 8 would represent how far up the 10-foot ladder reaches the wall.

Therefore:

18/10 = (x + 8)/8

9/5 = (x + 8)/8

Cross multiply

9*8 = 5(x + 8)

72 = 5x + 40

72 - 40 = 5x

32 = 5x

Divide both sides by 5

32/5 = x

x = 6.4

The 10-foot ladder would be, 6.4 + 8 = 14.4 ft far up the wall.

Answers

Answer:

40%

Step-by-step explanation:

A department store buys 300 shirts at a cost of $3,600 and sells them at a selling price of $20 each. Find the percent markup.

The formula for Percent Markup is given as:

Selling price - Cost price/Cost price × 100

Cost price = $3,600

Selling price = $20 × 300 shirts

= $6000

Percent Markup = $6000 - $3600/6000 × 100

= 2400/6000 × 100

= 40%

The percent Markup is 40%

Under his cell phone plan, Bentley pays a flat cost of $64.50 per month and $4 per gigabyte. He wants to keep his bill at $78.90 per month. How many gigabytes of data can he use while staying within his budget?

Answers

Answer:

3.6 gB

Step-by-step explanation:

You can think of this question in terms of the y = mx+b equation.

$78.90 is y because it is the total amount per month, $4 is m because it is the cost per gB, and $64.50 is b because it is the flat rate.

78.9 = 4x + 64.5

4x = 14.4

x = 3.6 gB of data (or 3 if it wants a whole number)

Find the length of the intercepted arc and sector in a circle with a radius of 6 cm and a central angle of
132 degrees.

Answers

Answer:

Arc length = 13.818

Step-by-step explanation:

First, you will need to convert the 132 degrees to radians.

To convert, you'll have to multiply by π/180. So 132 x π/180 = 2.303.

Now with that value, you'll have to multiply by the radius to obtain the arc length.

2.303 x 6 = 13.818

Central angle = 132

Radius = 6

Diameter = 6 x 2 = 12

Arc length = 13.818

costs $329. And, the 32 oz container cost $1.99. Which size has the lowest price per fluid
ounce?

Answers

Answer:

128 divided by $4.59 = 27.88671023965142
64 divided by $329 = 0.19452887537994
32 divided by $1.99 = 16.08040201005025

Therefore, the size which has lowest price per fluid ounce is 32 fl. oz container .
