What are the domain and range of each relation? Drag the answer into the box to match each relation. A mapping diagram. Element

x contains negative 2, negative 1, 0, and 2. Element y contains negative 4, negative 2, and 2. Negative 2 maps to negative 4. Negative 1 maps to negative 2 and 2. Zero maps to negative 4. Two maps to 2. x y −4 −2 −2 1 1 4 4 4 Domain: {−4, −2, 1, 4} Range: {−2, 1, 4} Domain: {−2, −1, 0, 2} Range: {−4, −2, 2} Domain: {−4, −2, −1} Range: {−2, 0, 1}

Answer:

Domain: {−2, −1, 0, 2} Range: {−4, −2, 2}

Step-by-step explanation:

We have been given a mapping diagram as shown below:

X Y

-2 -4

-1 -2

0 2

2


For better view, you can check the attached mapping diagram.

From that diagram we have to find domain and range.

Domain contains only x values so domain will be:

Domain: {-2,-1,0,2}

Range contains only y values so range will be:

Range: {-4,-2,2}

We see that only third choice matches obtained values of domain and range.

Hence final answer is  Domain: {−2, −1, 0, 2} Range: {−4, −2, 2}

A certain group of women has a 0.86​% rate of​ red/green color blindness. If a woman is randomly​ selected, what is the probabil
Mariana [72]

Answer:

The probability that a randomly selected woman has red/green color blindness is 0.9914

Step-by-step explanation:

Given that the proportion of women having red/green color blindness is 0.86%

Represent that with p

p= 0.86\%

Convert proportion from percentage to decimal;

p= \frac{0.86}{100}

p= 0.0086

In probability; opposite probabilities add up to 1;

Let the probability that a woman selected have red/green color blindness be represented with q;

p + q = 1

Subtract p from both sides

p - p + q = 1 - p

q = 1 - p

Substitute 0.0086 for p

q = 1 - 0.0086

q = 0.9914

<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>

In Winter of 2020 there were 20 total inches of snow. In Winter 2021 there were 38 total inches of snow. What was the percer
nikdorinn [45]

To find the answer, you need to subtract the total inches of snow in 2021 by the total inches of snow in 2020.

So 38 -20= 18

Therefore,  from 2020 to 2021. The snow increased by 18 inches.

Hope this helped!
