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

Need help with this problem
alexandr1967 [171]

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar the ratios of corresponding sides are equal

\frac{20}{20+8} = \frac{3x}{4x+2}, that is

\frac{20}{28} = \frac{3x}{4x+2} ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10

If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.
Leto [7]

Answer:

y = 6

Step-by-step explanation:

If x varies inversely proportional as y.

x=\dfrac{k}{y}, k is constant of proportionality

or

k = xy

When x = 3 and y = 10

k = 3×10

k = 30

Put x = 5,

y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6

So, the value of y is 6 when x is 5.
