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.

You deposit $800 in an account that pays 8% annual interest compounded quarterly. About how
long will it take for the balance to triple?

Answers

Answer: t = 13.73


Explination:

Youre going to use the equation A= Pe^rt
A= 2400 (800 trippled)
P= 800 because thats your deposit
E=0.08 (this is 8% as a decimal)
T= time, this is what youre going to find since its how long for it to tripple

Now lets do the math

2400. 800 e^0.08%
——— = ———————-
800 800

(Take 2400/800 this equals 3)
Now you’ll have this
3= e^0.08

Ln 3 = Ln e^0.08t
Ln3=0.08t Ln e

Now we have to get rid of 0.08

Ln 3 0.08t
——— = ————
0.08 0.08

Now in your calculator:

Ln (3) / 0.08 = 13.73265…..

So rounding this gives 13.73
T=13.73

Solve the equation. Determine the solution(s) and any extraneous solution.
√2x = x - 4

Answers

I assume you mean the equation

√(2x) = x - 4

Take the square of both sides. Note that √(2x) is a non-negative number, so any solution we find must also satisfy x - 4 ≥ 0, or x ≥ 4.

(√(2x))² = (x - 4)²

2x = x² - 8x + 16

x² - 10x + 16 = 0

(x - 8) (x - 2) = 0

x - 8 = 0   or   x - 2 = 0

x = 8   or   x = 2

If x = 2, then x ≥ 4 is false. The only solution is then x = 8.

Kofi is 8years old and his mother is 42. In how many years will his mother's age be 3 times more than kofi's age?​

Answers

Answer:

After 9 years mother's age will be 3 times more than kofi's age .

Step-by-step explanation:

Given

Age of Kofi = 8 years

Age of Mother = 42 years

According to question , 3 times more than kofi's age .

=> ( 8+ x ) 3 = 42 + x

=> 24 + 3x = 42 + x

=> 3x - x = 42 - 24

=> 2x = 18

=> x = 18/2

=> 9

After 9 years ,

Age of Kofi = 8 + 9 = 17 years Age of Mother = 42 + 9 = 51 years

One morning the temperature in Bangor, Maine was 18 degrees. By afternoon, it had dropped 20 degrees. The afternoon temperature in Bangor, Maine, was -2 degrees.

To find the afternoon temperature, we need to subtract 20 degrees from the morning temperature of 18 degrees.

Afternoon temperature = Morning temperature - Temperature drop

Afternoon temperature = 18 degrees - 20 degrees

To perform the subtraction, we have to handle negative numbers:

Afternoon temperature = 18 degrees - 20 degrees

Afternoon temperature = -2 degrees

So, the afternoon temperature in Bangor, Maine, was -2 degrees.

Pythagoras’ Theorem:    [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Area of a square = x²  (where x is the side length)

------------------------------------------------------------------------------------------------------

Assuming that all the quadrilaterals are squares.

Side length of blue square with area 16 m² = √16 = 4 m

Side length of yellow square with area 9 m² = √9 = 3 m

Use Pythagoras' Theorem to find the length of b:

[tex]\implies b^2=25[/tex]

[tex]\implies b=\sqrt{25}[/tex]

Side length of purple square with area 144 m² = √144 = 12 m

Can someone help me with the steps to create the formula? It involves quadratics​

Answers

The formula of the quadratic function passing through the points (-2,0), (8,0) and (2, -24) is f(x) = x² - 6x - 16

How to create the formula?

The points are given as:

(-2,0) , (8,0) and (2, -24)

The points (-2,0) and (8,0) are the zeros of the function.

So, we have:

f(x) = a(x + 2)(x -8)

Substitute (2, -24) in the above equation

-24 = a(2 + 2)(2 -8)

Evaluate the sum and the difference

-24 = a(4)(-6)

Divide both sides by -24

a = 1

Substitute a = 1 in f(x) = a(x + 2)(x -8)

f(x) = (x + 2)(x -8)

Expand

f(x) = x² + 2x - 8x - 16

Evaluate the like terms

f(x) = x² - 6x - 16

Hence, the formula of the quadratic function is f(x) = x² - 6x - 16
