Answer:

48 apartments.

Step-by-step explanation:

First me must find out what 25% of 64 is, so we multiply 64 • 0.25 to get 16.

In other words, 16 is the same as 25% of 64.

If we take 16 and subtract it from the total of 64 we get 48, or 75% (100% - 25% = 75%)

Answer:

48 apartments did not have a view of the park.

Step-by-step explanation:

25% of 64 (total)= 16 (number of people with view)

64 ( total)-16 (# of people with a view)= 48 (number of people without a view)

Answer:

(B) P(B)=\dfrac{16}{31}

Step-by-step explanation:

From the Venn diagram, n(AUB)=31

The given probabilities in the option are calculated below:

P(A)=\dfrac{21}{31}\\\\P(B)=\dfrac{16}{31}\\\\P(A|B)=\dfrac{P(A\cap B)}{P(B)}= \dfrac{6/31}{16/31} =\dfrac{6}{16}=\dfrac{3}{8} \\\\P(B|A)=\dfrac{P(B\cap A)}{P(A)}= \dfrac{6/31}{21/31} =\dfrac{6}{21}=\dfrac{3}{7}

The only correct option is the probability of B which is \frac{16}{31}

The 40th parallel of north latitude runs across the United States through Philadelphia, Indianapolis, and Denver. At this latitu
Ronch [10]

Answer:

793.25 mi/hr

Step-by-step explanation:

Given that:

The radius of the earth is = 3030 miles

The angular velocity = \dfrac{\pi}{12} rads

If a jet flies due west with the same angular velocity relative to the ground at the equinox;

We are  to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.

NOW;

Distance s is expressed by the relation

s = rθ

s = 3030(\frac{\pi}{12} )

s = 793.25

The speed which depicts how fast in miles per hour the jet would have traveled is :

speed (v) = \frac{s}{t}

v = \frac{793.25}{1}

v = 793.25 mi/hr

Hence, the jet would have traveled 793.25 mi/hr due west at the  40th parallel for this to happen.
