The minimum and maximum temperature for a day in Cupcake Town can be modeled by the equation below: 3|x − 8| + 15 = 18 What are the minimum and maximum temperatures for this day?

Answers

Answer 1

Answer: 3|x − 8| =18 - 15 = 3
|x − 8| = 3/3 = 1
x − 8 = $\pm1$
x = $\pm1$ + 8
x = 1 + 8 or x = -1 + 8
x = 9 or x = 7
i.e. minimum temperature is 7 while the maximum temperature is 9

Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? (trust me) 13 in.

Answers

Answer:

$DC=13\ in$

Step-by-step explanation:

we know that

in a parallelogram, opposite sides are congruent

In this problem

AB and DC are opposite sides

therefore

AB=DC

substitute the given values

$9x-14=3x+4$

solve for x

$9x-3x=4+14\n6x=18\nx=3$

Find the length of side DC

$DC=3x+4$

substitute the value of x

$DC=3(3)+4=13\ in$

Which description best describes the association between the years and population in this scatter plot?

Answers

Answer:

"moderate negative"

Step-by-step explanation:

When two variables are correlated, a tendency, negative or positive, can be distinguished in the dispersion chart.

When the trend is positive it means that one variable increases when the other also increases.

When the trend is negative it means that one variable decreases as the other increases ..

The relationship between both variables can be strong or weak.

If the relationship is strong, the points in the scatter diagram will increasingly resemble a line (if it is a linear relationship).

If the relationship is weak, the points will be more and more scattered without any relation between them.

In this case it is observed that when the years increase the population decreases. Therefore it is a negative relationship. The distribution of the points resemble moderately to a straight line. Therefore, the correct option is "moderate negative"
