Answer:

The probability of getting a sum less than or equal to 4 is 1/6.

Step-by-step explanation:

When two dices are rolled, the number of outcomes are: 6*6 = 36 which is written in ordered pairs consisting of outcome of both dices.

When two dices are rolled, the number of sample space elements is:

$n(S) = 36$

Let A be the event that the sum of outcomes is less than or equal to 4:

$A = \{(1,1),(1,2),(1,3),(2,1),(2,2),(3,1)\}$

That implies

$n(A) = 6$

The probability of getting sum less than or equal to 4 will be:

$P(A) = \frac{n(A)}{n(S)} = \frac{6}{36} = \frac{1}{6}$

Hence,

The probability of getting a sum less than or equal to 4 is 1/6

Ryan created the two-way table below to describe his scoring in his soccer team’s wins and losses last season. Ryan’s Scoring in

pickupchik [31]

Answer: There is 40% of team's win that Ryan score a goal.

Step-by-step explanation:

Since we have given that

Team Won Team lost

Ryan scored 6 4

Did not score 9 11

(by Ryan)

-------------------------------------------------------------------------

Total 15 15

Percentage of team's win that Ryan score a goal is given by

$\dfrac{6}{15}\times 100\\\\=40\%$

Hence, there is 40% of team's win that Ryan score a goal.

Answer:

1.)4188.79

2.) 7238.23

3.)1.02

4.)4189

5.)170 cm³

Step-by-step explanation:

1.) 4πr2 * 5

2.) 4πr2 * 12

3.) V = 4/3(PI*r3). *4.5

4.) V = 4/3 π r ^3 * 10

5.) Given:

Cylindrical container: height = 18 cm ; diameter = 6 cm.

3 balls each have a radius of 3 cm.

Volume of a cylinder = π r² h

V = 3.14 * (3cm)² * 18 cm

V = 508.68 cm³

Volume of rubber ball = 4/3 π r³

V = 4/3 * 3.14 * (3cm)³

V = 113.04 cm³

113.04 cm³ * 3 balls = 339.12 cm³

508.68 cm³ - 339.12 cm³ = 169.56 cm³ or 170 cm³

There is 170 cm³ free space in the container.

Find the product. Your answer must be in simplest form.<br> 7/8 of 56

Leviafan [203]

Answer:

You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.

Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:

So now that we've converted 56 into a fraction, to work out the answer, we put the fraction 7/8 side by side with our new fraction, 56/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

7 x 56

8 x 1

392

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 392 and 8 is 8.

We can now divide both the new numerator and the denominator by 8 to simplify this fraction down to its lowest terms.

392/8 = 49

8/8 = 1

When we put that together, we can see that our complete answer is:

The complete and simplified answer to the question what is 7/8 of 56 is:

Hopefully this tutorial has helped you to understand how to find the fraction of any whole number. You can now go give it a go with more numbers to practice your newfound fraction skills.
