Answer:

The probability is 0.95

Step-by-step explanation:

In this question, we are interested in calculating the probability that a randomly selected student of the university recycles at least some of the times

Mathematically, the probability that student recycles at least some of time = 1 - probability that the student never recycles all the time

From the question, the probability that the student never recycles all the time = 0.05

Substituting this into the equation given above;

Probability that a randomly selected student at the university recycles at least some of the time = 1-0.05 = 0.95

JulijaS [17]

Answer:

y = -3+ rx

Step-by-step explanation:

Given

Base = -3C

Time = x

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

y = Base + Rate * Time

y = -3+ r* x

y = -3+ rx

Can someone help with this problem
WARRIOR [948]
35+25=60
y=60


If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.

The perimeter of a standard-sized rectangular rug is 36 is 36 ft. the length is 2 ft longer than the width. find the dimensions
evablogger [386]
The formula for the perimeter of a rectangle is P = 2L + 2W, where L is the length and W is the width. Because we don't know either the length or the width we can't solve the problem...too many unknowns.  BUT we do have some information that will help with this problem.  We are told that the length is 2 feet longer than the width, so we can use that: L = W+2.  Now we can make the substitution into the formula along with the value for the perimeter that was given to us: 36=2(W+2) + 2W, and 36 = 2W + 4 + 2W; 36 = 4W + 4; 32 = 4W and W = 8.  Now go back to where you said that the length is 2 feet longer than the width.  If the width is 8, then 8+2 = 10 for the length.

Use ratio and proportion

5.25/x= 82/100
cross multiply
82 x= 525
     x= 6.4 miles

Hope this helps
