A chair can be purchased in one of four colors: red, white, green, or blue. The number of chairs purchased in each color is list

Makovka662 [10]

Answer:

$P(Red) = 0.125$

Step-by-step explanation:

Given

$Red: 150$

$White: 450$

$Green: 225$

$Blue: 375$

Required

Determine the probability of getting a red chair, next.

First, we nee the total number of chairs

$Total = 150 + 450 + 225 + 375$

$Total = 1200$

Probability of getting red is then calculated as thus;

$P(Red) = Red/Total$

$P(Red) = 150/1200$

$P(Red) = 0.125$

My garden takes up 1/3 of my yard; I plant tomatoes in 1/2 of the garden. Write and solve the equation shown by the diagram to t

vekshin1

You’re going to divide 1/3 by 1/2.
1/3 divided by 1/2

Now here’s a reciprocal. That’s when you’re dividing 2 fractions and you flip 1 fraction and preform multiplication.

1 2 2
_ times _ = _
3 1 3

and you will get 2/3

Find the distance of PQ<br> P(0,4) and Q(10,-6)

solong [7]

Answer:

PQ ≈ 14.14 units

Step-by-step explanation:

calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = P (0, 4 ) and (x₂, y₂ ) = Q (10, - 6 )

PQ = $\sqrt{(10-0)^2+(-6-4)^2}$

= $\sqrt{10^2+(-10)^2}$

= $\sqrt{100+100}$

= $\sqrt{200}$

≈ 14.14 units ( to 2 dec. places )
