Answer:

\dfrac{5}{8}

Step-by-step explanation:

Alvin takes pictures with his smartphone.

Of the pictures \frac{5}{6} are animals.

\frac{3}{4} of the animals are dogs.

To find which fraction of all pictures are pictures with dogs, you can simply multiply two fractions:

\dfrac{5}{6} \times \dfrac{3}{4} =\dfrac{15}{24} =\dfrac{5}{8}

<u>Another way</u> to solve this question:

Let the number of all pictures be 24 (divisible by both 4 and 6).

Then the number of pictures with animals is

\dfrac{5}{6} \times 24=5\times 4=20

and the number of pictures with dogs is

\dfrac{3}{4} \times 20=3\times 15

Hence, the fraction of pictures with dogs of all pictures is

\dfrac{15}{24}=\dfrac{5}{8}

3/4 of 5/6 are dogs.

When you see the word "of," you should multiply.

3/4 * 5/6 = 15/24

Simplified: 5/8

​If Alfie tosses the paper cup more times, what is the expected ​number of times that the cup will land on its side?
IRINA_888 [86]

Question:

Alfie tossed a paper cup in the air 150 times and recorded the side it landed on.

     Right side up = 60         Upside down = 53             Side = 37

If Alfie tosses the paper cup 100 more times what is the expected number of times the cup will land on its side?

 

Answer:

The expected number of times the cup will land on its side is 25 times

Step-by-step explanation:

Given

Right = 60

Upside\ down = 53

Side = 37

Required

First, we calculate the probability of landing on side

P(Side) = \frac{n(Side)}{Total}

P(Side) = \frac{37}{150}

P(Side) = 0.247

Next, we calculate the expected value; E(x) using:

E(x) = n * P(x)

When tossed 100  more times:

n = 100 and P(x) = P(Side) = 0.247

So:

E(x) = 100 * 0.247

E(x) = 24.7

E(x) = 25 --- approximated

<em>Hence, it is expected that it will land on its side 25 times</em>

A circular hot spring has a diameter of 76 meters. Over time, the diameter of the spring decreases by 4 meters. By how many squa
VikaD [51]

Answer:

<h2>The area of the spring decreases by  370.52*10⁴cm²</h2>

Step-by-step explanation:

The formula for calculating the area of the circular hot spring = \pi r^{2} or \frac{\pi d^{2} }{4}

Initial area of the spring with diameter of 76metres is as shown

= \frac{\pi (76)^{2} }{4} \\= 1444\pi m^{2}

If the diameter of the spring decreases by 4 meters over time, the new diameter after decrease will be 76meters less 4 meters which is 72metres.

New area;

\frac{\pi (72^{2} )}{4}\\ = 1296\pi m^{2}

Decrease in area = 1444πm²-1296πm²

Decrease in area = 148πm²

= 370.53m²

since  1m²=10⁴cm²

then 370.53m² = 370.52*10⁴cm²
