Last year, the number of skateboards produced by a skateboard company is normally distributed. The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year. Use this information to find the average number of skateboards produced per day last year.

Answers

The average number of skateboards produced per day last year is 310.

What is a normal distribution?

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year.

Z- score at 93.32% is -1.5

We know:

[tex]\rm Z = \dfrac{(x - \mu)}{\sigma}[/tex]

[tex]\rm -1.5 = \dfrac{(280 - \mu)}{20}[/tex]

μ = 280 + 30

μ = 310

Thus, the average number of skateboards produced per day last year is 310.

Find the area of the kite

Answers

Answer:

180

Step-by-step explanation:

(10×11)+(10×7)=110+70

The area of the kite is expressed as 1/2 × (Product of its diagonals)

In this case, we have;

Diagonal₁ - 10 + 10 feet = 20 feetDiagonal₂ - 7 + 11 feet = 18 feet

Therefore, when we substitute the diagonals in the formula, we get;

⇒ 1/2 × (Product of its diagonals)⇒ 1/2 × (20 × 18)

When simplified, we get;

⇒ 1/2 × (20 × 18)⇒ 1/2 × (360)⇒ 360/2 = 180 ft²

Therefore, the area of the kite is 180 ft².

Which of the following inequalities matches the graph?

Answers

Answer:

6x - y < -3

Step-by-step explanation:

When graphing inequalities:

< or > = dashed line

≤ or ≥ = solid line

< or ≤ = shade below the line

> or ≥ = shade above the line

Create an equation for the line

Choose 2 points on the line:

let (x₁, y₁) = (-1, -3)let (x₂, y₂) = (0, 3)

Calculate the slope:

[tex]\sf \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-3)}{0-(-1)}=6[/tex]

Determine the equation for the line using the point-slope formula:

[tex]\implies\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-(-3)=6(x-(-1))[/tex]

[tex]\implies \sf y+3=6(x+1)[/tex]

[tex]\implies \sf y=6x+3[/tex]

As the shading is above the line:

⇒ y > 6x + 3

Compare with answer options

Rearrange each answer option to make y the subject:

Option (a)

-6x + y < 3

⇒ y < 6x + 3

Option (b)

6x + y < 3

⇒ y < -6x + 3

Option (c)

6x - y < -3

⇒ -y < -6x - 3

⇒ y > 6x + 3

Therefore, as option C matches the calculated inequality, the answer is

6x - y < -3

Answer:

6x - y < 3

Step-by-step explanation:

Finding the equation of the inequality :

Slope :

⇒ m = 3 - (-3) / 0 - (-1)

⇒ m = 6/1

⇒ m = 6

Y-intercept :

⇒ (0, 3)

Equation :

⇒ y = 6x + 3

Here :

⇒ Above the origin, so it is greater than ( > )

⇒ y > 6x + 3

6x - y < 3
