Answer: Slope: -1 Y-intercept: -4

Step-by-step explanation:

Slope formula:

$m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

$m=\frac{-13 -(-6)}{9-2}= m=\frac{-13 + 6}{9-2}$

$m=\frac{-7}{7\\}$

m = -1

When you draw this on the graph, the y-intercept is -4.

y = -4

Let X = the number of nonzero digits in a randomly selected 4-digit PIN that has no restriction on the digits. What are the poss

NISA [10]

Answer:

X = {0, 1, 2, 3, 4}

Step-by-step explanation:

If X is the number of nonzero digits in a 4-digit PIN with no restriction on the digits, the pin can have up to 4 nonzero digits.

Let's see some examples:

If the PIN is 0000 then X = 4

If the PIN is 2045 then X = 3

If the PIN is 7546 then X = 0

From the previous examples, we can see that the possible values for X are 0, 1, 2, 3, 4.

Thus X = {0, 1, 2, 3, 4}

Luke shaded 20 squares on his hundredths grid. Bekka shaded 30 squares on her hundredths grid. Write two decimals greater than L

Rus_ich [418]

Luke's original decimal is 0.20 and Bekka's is 0.30 so 0.40 and 0.50 would be greater than Luke's original and 0.20 and 0.10 are lesser than Bekka's original decimal

Julio says if you subtract 17 from my number and multiply the difference by - 2 the result is gonna be negative 12 what was Juli

Paha777 [63]

Answer:

Step-by-step explanation:

Taking an algebraic approach

let the number be n, then (n - 17) is 17 subtracted from number and

- 2(n - 17) = - 12 ( divide both sides by - 2 )

n - 17 = 6 ( add 17 to both sides )

n = 23

Thus Julio's number was 23

When grading an exam, 90% of a professor's 50 students passed. If the professor randomly selected 10 exams, what is the probabil

Damm [24]

Using the binomial distribution, it is found that there is a:

a) 0.9298 = 92.98% probability that at least 8 of them passed.

b) 0.0001 = 0.01% probability that fewer than 5 passed.

For each student, there are only two possible outcomes, either they passed, or they did not pass. The probability of a student passing is independent of any other student, hence, the binomial distribution is used to solve this question.

<h3>What is the binomial probability distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
