Answer:

The experimental probability is given by the results of the experiment.

The coin landed heads up 12 out of 20 times. Divide the amount of times it landed heads up by the amount of times you flipped the coin

12 divided by 20=0.6

Multiply this decimal by 100 to get the percentage:

0.6 times 100=60

The experimental probability of the coin landing heads up is 12/20, or 3/5, or 60%.

The theoretical probability is given by the chances of landing the coin heads up.

There are two outcomes: the coin landing heads up, and the coin landing tails up. Out of two outcomes, you want one.

Theoretical probability is given by the amount of wanted possibilities over the total possibilities. You want 1 out of 2 to occur, so the theoretical probability is 1/2, or 50%.

Which set of ordered pairs represents a function? {(−1,−3),(0,−7),(3,3),(3,−4)} {(7,9),(−5,7),(−5,8),(4,−4)} {(−6,−1),(−8,4),(−5

Jlenok [28]

Ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.

As given in the question,

Given set of ordered pairs following is the one which represents the function :

{(−1,−3),(0,−7),(3,3),(3,−4)}

In the given set of ordered pair for input value 3 there are two outputs 3 and -4 , therefore it is not a function.

{(7,9),(−5,7),(−5,8),(4,−4)}

In the given set of ordered pair for input value -5 there are two outputs 7 and 8 , therefore it is not a function.

{(−6,−1),(−8,4),(−5,4),(3,−9)}

In the given set of ordered pair each input has unique single output. Therefore it is a function.

{(−1,0),(−1,−4),(8,−3),(−4,−6)}

In the given set of ordered pair for input value -1 there are two outputs 0 and -4 , therefore it is not a function.

Therefore, ordered pair{(−6,−1),(−8,4),(−5,4),(3,−9)} from the given set of ordered pairs represents the function.

How do i solve z+18=y

lubasha [3.4K]

<span>Simplifying z + 18 = y Reorder the terms: 18 + z = y Solving 18 + z = y Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + z = -18 + y Combine like terms: 18 + -18 = 0 0 + z = -18 + y z = -18 + y Simplifying z = -18 + y</span>

Find the volume of a triangle prism with the following dimensions triangle base: 5ft

Andrews [41]

Hey there :)

We know the volume formula of a triangular prism
Volume = base area × height of prism

We are given:
Base of triangle = 5 ft
Height of triangle = 3 ft
Height of prism = 7.5 ft

Apply the formula
V = $\frac{1}{2}$ ( 5 )( 3 ) × 7.5
= 7.5 × 7.5
= 56.24 ft³

Michael ran 655 feet in 19 seconds jasmine ran 1 mile in 4 minutes and 24 seconds in miles per hour and to the nearest tenth how

Natalka [10]

Answer:

Step-by-step explanation:

<h3>Step 1: Convert miles to feet</h3>

First, we need to convert the miles to feet keeping in mind that:

1 mile = 5,280 feet

655 ft 19 sec

5,280 ft 4 min 24 sec

<h3>Step 2: Divide the distance by the time to find the unit rate</h3>

3,447 feet per minute

1,245 feet per minute

<h3>Step 3: Convert minutes to hours</h3>

206,820 feet per hour

74,700 feet per hour

<h3>Step 4: Convert feet to miles</h3>

39.17 miles per hour

14.15 miles per hour

To find how much faster Michael ran, we need one more step.

<h3>Step 5: Subtract smaller amount from larger amount</h3>

39.17 - 14.15 = 25

I'm always happy to help :)
