A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv
Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. P(Red) = 0.4375

b. P(White) = 0.3125

Step-by-step explanation:

Given

Red = 7

White = 5

Yellow = 4

First, we need to calculate the total

Total = Red + White + Yellow

Total = 7+5+4

Total = 16

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

P(Red) = \frac{Red}{Total}

P(Red) = \frac{7}{16}

P(Red) = 0.4375

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

P(White) = \frac{White}{Total}

P(White) = \frac{5}{16}

P(White) = 0.3125

Soni has 196 pencils. If she puts equal amounts of pencils into eight boxes, she has four pencils left. How many pencils does sh
Kryger [21]
The best way to work this out is to find the total number, minus the remained. In this case, subtract four from 196, and this gives you 192. As you've got to put the pencils into 8 boxes, you have to divide 192 by 8, and this gives you 24.
Therefore, Soni can put 24 pencils can be put into each box, with four pencils remaining.
Hope this helps :)

Answer:

a5 = 2604

Step-by-step explanation:

a1 = 4

a2 = -5(4)-1 = -21

a3 =-5(-21)-1 = 104

a4 = -5(104)-1 =-521

a5 =-5(-521)-1 = 2604

Tawnee is designing a playground in the shape of a rectangle. If Tawnee increases the length and width of the playground by a sc
svetlana [45]

Answer:

We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Step-by-step explanation:

We know that the perimeter of a rectangle = 2(l+w)

i.e.

P = 2(l+w)

Here

  • 'l' is the length
  • 'w' is the width

Given that the length and width of the playground by a scale factor of 2

A scale factor of 2 means we need to multiply both length and width by 2.

i.e

P = 2× 2(l+w)

P' = 2 (2(l+w))

    = 2P      ∵ P = 2(l+w)

Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.
