Answer 4/91  I don't know I'm not good at math but I hope it's right :)

Step-by-step explanation:  Convert mixed numbers into improper fractions: 22/3/4 = 91/4

= 1 ÷ 91/4

Convert element to fraction: 1 = 1/1

= 1/1 ÷ 91/4

Apply the fraction rule: = 1/1 x 4/91

Apply rule: a/a = 1

1/1 = 1

= 1 x 4/91

Multiply: 1 x 4/91 = 4/91

= 4/91

What is the average distance between the parabola y=30x(20-x) and the x-axis on the interval [0, 20]?
Anni [7]

Answer: the average distance between the parabola is 2000

Step-by-step explanation:

Given that;

y = 30x(20 - x) and the x-axis on the interval [0, 20]

f(x) = y = 30x(20 - x); [0, 20] and a=0, b=20

the average distance between the parabola will be

Average value = 1/20-0 ²⁰∫₀ 30x(20-x) dx

= 1/20 ²⁰∫₀ (600x-30x²) dx

= 1/20 [(600x)/2 - (30x³)/3]₀²⁰

= 1/20 [300x - 10x³]₀²⁰

inputting the limits, we get

= 1/20 [(300 × 20 × 20 - 10 × 20 × 20 × 20) - 0 - 0]

=  1/20 ( 120000 - 80000)

= 0.05 × 40000

<h2>= 2000</h2>

Therefore the average distance between the parabola is 2000

A bag contains different colored candies. There are 50 candies in the bag, 28 are red, 10 are blue, 8 are green, and 4 are yello
Sauron [17]

Answer:

21/25

Step-by-step explanation:

First we need to find the probability of getting a candy that is green

P(green) = green/total

              = 8/50

            = 4/25

We know that

P ( not green) = 1 -P(green)  

because these are the only two events that can happen

Either the candy is green or it is not green.

P ( not green) = 1 - 4/25

                        = 25/25 - 4/25

                        = 21/25

A subway train is traveling at a rate of 22.4 m/s. Brakes are applied and it slows down at a constant rate of 3.5 m/s2 until it
WARRIOR [948]

You use the equation Final Velocity²= (Initial Velocity)² 2(Acceleration)(Distance). You plug in what you have 0²=22.4² X 2(-3.5)(D) and solve for D which is 71.68m or about 72m.

Use the value of the linear correlation coefficient r to find the percentage of the total variation that can be explained by the
Pie

Answer:

5.47% of the total variation between the two variables can be explained by the regression line.

Step-by-step explanation:

Given :

R value = 0.234

The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.

However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².

R² value is Obtained by taking the squared of the correlation Coefficient

Hence,

R² = 0.234² = 0.054756

R² = 0.05476 * 100% = 5.4756%

Hence, R² = 5.48%

This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.
