M&M plain candies come in various colors. According to the M&M/Mars Department of Consumer Affairs, the distribution of

lyudmila [28]

Answer:

A) 0.12. Yes. Choosing a green and blue M&M is possible

B) 0.43. Yes. Choosing a yellow and red M&M is possible

C) 0.78

Step-by-step explanation:

First of all, the summation of the distribution of all colours is;

Σ(all colors ) = 22% + 20% + 23% + 10% + 6% + 6% + 13% = 100%, or 1.

Thus;

a) P(green candy or blue candy) is;

P(GREEN ∪ BLUE) = P(G) + P(BL)

P(GREEN ∪ BLUE) = 6%+6%

P(GREEN ∪ BLUE) = 12% or 0.12

Now, due to the fact that we have to choose ONE candy and only ONE candy at random, then they are mutually exclusive: Yes. Choosing a green and blue M&M is possible

b)P(yellow candy or red candy is;

P(YELLOW ∪ RED) = P(Y) + P(R)

P(YELLOW ∪ RED) = 20% + 23% = 43% or 0.43

Yes. Choosing a yellow and red M&M is possible

c) P(NOT PURPLE)

the probability of having a purple is;

P(PURPLE) = 22% or 0.22

So, the Probability of NOT having a PURPLE is 1 - 0.22 = 0.78

2) As part of traffic accident investigations, the speed of a car involved can be approximately determined by checking actual sk

dezoksy [38]

a) The speed of car was 60 mph.

b) The speed of car was 45 mph.

Step-by-step explanation:

Given,

a = actual skid marks

p = test skid marks

Formula;

$s=30*\sqrt{\frac{a}{p}}\\$

a) a = 144 feet, p = 36 feet

Putting in formula;

$s = 30*\sqrt{\frac{144}{36}}\\\\s=30*\sqrt{4}\\\\s=30*2\\\\s=60$

The speed of car was 60 mph.

b) a = 153 feet, p = 68 feet

Putting in formula;

$s=30*\sqrt{\frac{153}{68}}\\\\s=30*\sqrt{2.25}\\\\s=30*1.5\\\\s=45$

The speed of car was 45 mph.

Choose the appropriate description for the equation. Given: x 2 + y 2 = 36

Ganezh [65]

Answer:

The equation represent a circle with center at the origin and radius 6 units

Step-by-step explanation:

we know that

The equation of a circle in center radius form is equal to

$(x-h)^{2}+(y-k)^{2}=r^{2}$

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

$x^{2} +y^{2}=36$

the center of the circle is the origin $(0,0)$

and the radius is

$r=\sqrt{36}=6\ units$

therefore

The equation represent a circle with center at the origin and radius 6 units
