Answer:

\frac{2}{15}

Step-by-step explanation:

Number of students participating in the competition = 13.

Total number of students in the school = 15.

Thus ,

the number of students who did not make to this competition =

Total number of students - number of students participated

= 15-13 = 2.

Now ,

probability of the student who do not makes it to the competition

= fraction of students who did not make to this competition from the total number of students .

=\frac{2}{15}.

PLEAZE HELP IM FAILING THIS CLASS 9) The volume of a box is represented by x' +11x² + 20x – 32. The width of the box is x – 1, a
In-s [12.5K]

Answer:

Step-by-step explanation:

Volume of the box  =  x³ +11x² + 20x – 32        I think the ' is a typo for ³

      the width is x-1    and the height is x+8      

Find an expression for the length

       Vol = LWH    solve L

        Vol / (WH)   =  L     so

L  =  (x³ +11x² + 20x – 32) / (x-1) (x+8)      

                    so it would help to factor the numerator

       (x³ +11x² + 20x – 32)       I'm willing to bet (x-1) and  (x+8) are factors

                                               but I will plot the equation to find the three roots

        (x³ +11x² + 20x – 32)  = (x-1) (x+8) (x+4)

L  =  (x³ +11x² + 20x – 32) / (x-1) (x+8)

   =  (x-1) (x+8) (x+4) / (x-1) (x+8)           the (x-1) and (x+8) cancel out leaving

L =   (x + 4)

ExtremeBDS [4]

Answer:

(y - 3) = 2(x - 2)

Step-by-step explanation:

Slope = (3 + 5) / (2 + 2)

Slope = 2

Choose a point: (2, 3)

(y - 3) = 2(x - 2)

Answer:

Null hypothesis H_0; \mu=5

Alternative hypothesis H_a; \mu\neq 5

Step-by-step explanation:

Consider the provided information.

The shower by an adult is 5 minutes.

The mean amount of time that college students spend in the shower is significantly different from 5 minutes. In a sample of 15 students, he found the average time was 4.29 minutes and the standard deviation was 0.75 minutes.

We need to determine the appropriate null and alternative hypotheses.

A null hypothesis is there is no statistical significance between the two variables.

An alternative hypothesis is there is a statistically significant relationship between two variables.

Therefore the required null and alternative hypothesis are:

Null hypothesis H_0; \mu=5

Alternative hypothesis H_a; \mu\neq 5

Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to d
inna [77]

Write <u>two functions</u> that <u>describes</u> the <u>decrease of the population</u> after <u>t years.</u>

1.  In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. Then after t years the number of orngutans will be

y=784-25t.

2.  In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. Then after t years the number of orngutans will be

y=817-36t.

3. Equate right sides of the equations:

784-25t=817-36t,\\ \\36t-25t=817-784,\\ \\11t=33,\\ \\t=3\ years.

Answer: after 3 years
