Answer:

5/18

Step-by-step explanation:

<u>Positive two-digit numbers are:</u>

  • Numbers in 10 - 99 interval

<u>Total two-digit numbers:</u>

  • 99 -9 = 90

<u>Number of two-digit numbers ≥ 75:</u>

  • 99 - 74 = 25

<u>Probability that the number is at least 75:</u>

  • 25/90 = 5/18

<u>Answer is</u> 5/18

A) 15/4 = 4/4+4/4+4/4+3/4= 3 3/4
B)9/2= 2/2+2/2+2/2+2/2+1/2= 4 1/2
c = 26/12 = 12/12 + 12/12 + 2/12 =  2 2/12
d) 20/6 = 6/6 + 6/6 + 6/6 + 2/6 = 3 2/6

Use the double intercept approach to find the graph of –1 = –y + x. A. B. C. D.
navik [9.2K]

Answer:

Intercepts at (-1, 0) and (0, 1).

Step-by-step explanation:

The double intercept form for the equation of a line is

ax + by = 1

-1 = -y + x

<em> y = 0 </em>

<em> </em>x = -1     Multiply each side by -1

-x = 1

The <em>x-intercept</em> is at (-1, 0).

=====

<em> x = 0 </em>

-1 = -y     Multiply each side by -1

y = 1

The <em>y-intercept</em> is at (0, 1).

=====

The graph (see below) is a straight line passing through the points (-1, 0) and (0, 1).

What is the slope of the segment shown for a staircase with 10-inch treads and 7.75-inch risers? As you walk up (or down) the st
s2008m [1.1K]

The formula for slope is

Slope = Rise / Run = Risers / Treads

Slope = 7.75 in /10 in = 0.775

The slope Is 0.775.

The vertical distance is not continuous, thus it is discrete. A discrete function only allows certain points in the interval. When you walk up or down the stairs, the vertical distances are not continuous because of the treads. You cannot stay also mid-air, so it should be discrete. An example of a continuous function would be when you walk up or down an inclined plane.
