Answer 2

The probability of the events are given as 0.6 and 0.2 respectively.

What is probability?

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

(a) The total number of elements in sample space are 10.

Then, the probability of getting numbers from 2 - 7 is given as,

P(numbers 2-7) =  Number of favorable outcomes ÷ Total outcomes

⇒ 6 ÷ 10 = 0.6

(b) The multiples of 5 are given as 5 and 10

Then, P (Multiple of 5) = Number of favorable outcomes ÷ Total outcomes

⇒  P (Multiple of 5) = 2/10 = 0.2

(c) The complement of selecting one element represents the selection of all remaining elements in the sample space.

Thus, complement of 9 represents selection of all the remaining numbers  from 1 to 10.

(d) For the probability of 3/10, the question can be asked as to find the probability of selecting numbers from 1 to 3.

Hence, the probabilities of the given events can be found by taking the ratio of favorable outcomes to the total outcomes.

An Olympic pool is rectangular with a length of 50 meters. Ms Burri wants to fit an Olympic pool in her backyard but doesn't have enough room so she plans to build a similar pool with a length of only 30 meters.

a. She wants to replace the pool deck around her new smaller pool. What is the ratio of the perimeter of the Olympic pool to the new smaller pool?

b. The area of the olympic pool is 1,2500 meters squared. If she were to buy a pool cover to fit her brand new smaller pool, what would the area be?

Answers

Perimeter of older

2(50+W)100+2W

Perimeter of newer

2(30+W)60+2W

As w is constant cancel it

Ratio

100/605/3

Ratio of area is also same

So

5/3=12500/x5x=37500x=37500/5x=7500m²

Answer:

See below ~

Step-by-step explanation:

Finding perimeter of Olympic pool and regular pool :

P (olympic) = 2(l + w) = 2(50 + w) = 2w + 100P (regular) = 2(l + w) = 2(30 + w) = 2w + 60

Taking the ratio :

2w + 100 : 2w + 60100 : 605 : 3

Using ratios to find area of regular :

5 : 3 = 12,500 : aa = 12500/5 x 3 = 2500 x 3a = 7,500 m²

equation that shows 3 less than the product of 4 and m

Answers

The equation that shows 3 less than the product of 4 and m is 3 < 4m

Formation of equation

Formation of equation is a means of transforming statements into equations

The product of 4 and m is 4m

If 3 is less than the product of 4 and m, this is expressed as:

3 < 4m

Divide both sides by 4

3/4 < m

m > 3/4

Hence the equation that shows 3 less than the product of 4 and m is 3 < 4m

What is the area of the triangle?

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

we need to find the areas of each triangle in the pyramid.

The area of base = 15.6

The area of each outer triangle = 1/2 x 9 x 12

For the part 1 volume is 32.768 dm³, for part 2 side length is  6 meters, and for part 3 the volume is 480 cubic cm.

What is a cube?

It is defined as three-dimensional geometry that has six square faces and eight vertices.

We have

1) Side length = 3.2 dm

Volume = (3.2)³ = 32.768 dm³

2) Volume of cube = 216 cubic meters

a³ = 216

a = 6 meters

3) The dimensions for sewing box: 10 cm, 8 cm, and 6 cm

Volume = 10×8×6 = 480 cubic cm

Similarly, we can calculate the rest of the data.

Thus, for the part 1 volume is 32.768 dm³, for part 2 side length is  6 meters, and for part 3 the volume is 480 cubic cm.

Step-by-step explanation:

Using the order of operations we need to work from left to right.

Therefore we should carry out the multiplication first.

5 × 5 means "5 lots of 5"

⇒ 5 × 5 = 5 + 5 + 5 + 5 + 5 = 25

Now we need to divide 25 by 8.

8 + 8 + 8 = 24

Therefore, 8 goes into 25 three times with a remainder of 1.

So,  5 × 5 ÷ 8 = 3 ¹/₈

What is the area of a rectangle?

The area of a rectangle is the multiplication of the length and the width of the rectangle.

The area of the rectangle is expressed as:

Area (A) = length (L) × width (w)

A = l × w

Given that:

width = xLength = 2x - 7Area = 72 in ²

72 = (2x - 7) × (x)

72 = 2x² - 7x

2x² - 7x - 72 = 0

Using the quadratic calculator

x = 8 or x = -9/2
