yaroslaw [1]

Answer:

Therefore, the probability is P=0.0084.

Step-by-step explanation:

We know that a multiple-choice test in which each question has 4 choices only one of which is correct. Assume that 9 questions are answered by guessing randomly.

Because we have 4 choices only one of which is correct, we get that p=0.25 and q=0.75.

We calculate the probability of getting exactly 6 correct answers.

n=9 and k=6.

$P=C_k^n\cdot p^k\cdot q^{n-k}\\\\P=C_6^9\cdot 0.25^6\cdot 0.75^3\\\\P=84\cdot 0.0001\\\\P=0.0084$

Therefore, the probability is P=0.0084.

If you were to write the equation of this line in the form y=mx+c what is the value of m

marusya05 [52]

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

$m = \frac{dy}{dx}$

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{1 - 0}{0 - 4} \\ m = \frac{1}{ - 4} \\ m = - \frac{1}{4}$

Therefore the value of m is - 1/4

Jenna has 2 whole watermelon and one-third of another watermelon. Write a mixed number and improper fraction to represent the am

galina1969 [7]

Well if she has 2 whole watermelons and 1/3 of one that would be 2 1/3 and that would be the mixed number and for the inproper fraction it would be 1 4/3 because you want to take out 1 from the 2 1/3 and add it on to the 1 of the 1/3 making it 1 and 4/3 I hope this helps!
