Answer:

Step-by-step explanation:

Using Pythagoras' identity to determine if the triangle is right

The square of the longest side should equal the sum of the squares on the other 2 sides, that is

QS² = RS² + QR² = 8² + 5² = 64 + 25 = 89 ( take the square root of both sides )

QS = $\sqrt{89}$

Δ QRS is not right as QS would have to be $\sqrt{89}$

Parking on campus is often expensive, and it is tempting to park illegally and take your chances on getting a ticket. From past

juin [17]

Answer:

P(not getting a ticket for 2 days) = 0.49

Step-by-step explanation:

We are told that the probability of getting a ticket on any given day is 0.3.

Thus;

P(getting a ticket a day) = 0.3

This means that;

P(not getting a ticket a day) = 1 - 0.3 = 0.7

Now, 0.7 is probability of not getting a ticket for 1 day. Since each day's outcome is independent of the previous day's outcome, it means that for n days, probability of not getting a ticket for n days will be;

P(not getting a ticket for n days) = 0.7ⁿ

For 2 days, its = 0.7² = 0.49

Thus;

P(not getting a ticket for 2 days) = 0.49

Write the pair of fractions as a pair of fractions with a common denominator 3/4 and 2/5

omeli [17]

Answer:

The common denominator $\frac{15}{20}$ and $\frac{8}{20}$

Step-by-step explanation:

To find the common denominator:

We have to find the LCD of the denominators.
Then multiply the fraction with the digit obtained from dividing the LCD with the denominator of the fraction concerned.

Here is the work:

LCD of $(4,5)$ is $(4\times 5)=20$ .
