A random two digit number (10-99) is drawn. Find P(odd number)
Mars2501 [29]

Answer:

P(odd number) = 0.5

Step-by-step explanation:

There are 90 members in the set (10, 11, 12, .. , 97, 98, 99)

When we have an even number of consecutive numbers, the number of even numbers equals the number of odd numbers. This means that half of the numbers in this set are even and half of them are odd.

So the probability of P(odd number) = 0.5

Find the slope of the line between points A and B. Simplify your answer.
Taya2010 [7]

Answer:

-2

Step-by-step explanation:

From the given graph, the point A(1, -4) and B(-1, 0)

Slope (m) = (y2 - y1) / (x2 - x1)

x1 = 1, y1 = -4, x2 = -1 and y2 = 0

Slope (m) = (0 - (-4))/(-1 - 1)

= 4/-2

Slope = -2

Thank you.

A mix of factoring by grouping. Factor the exressions. 17ax+17a-x-1 Please explain/show steps on how to do this!
mario62 [17]

Answer:

(x+1)(17a-1)

Step-by-step explanation:

We are given that

17ax+17a-x-1

We have to factorize the given expression.

Pair up the terms

(17ax+17a)+(-x-1)

Now, taking common factor

17a(x+1)-1(x+1)

Taking common (x+1)

(x+1)(17a-1)

Now, we get

(x+1)(17a-1)

This is required factors of given expression.
