Answer:
[tex]y = -\frac{2}{5}x -\frac{1}{5}[/tex]
Step-by-step explanation:
Given
Passes through: [tex](2,-1)[/tex]
Parallel to: [tex]2x + 5y = 15[/tex]
Required
First, calculate the slope of the parallel line
[tex]2x + 5y = 15[/tex]
Make y the subject
[tex]5y = 15 - 2x[/tex]
Divide through by 5
[tex]y = 3 - \frac{2}{5}x[/tex]
[tex]y =- \frac{2}{5}x+3[/tex]
An equation in slope intercept has the form:
[tex]y = mx + b[/tex]
Where:
m = slope
[tex]y = mx + b[/tex]
So:
[tex]m = -\frac{2}{5}[/tex]
The required is parallel to [tex]2x + 5y = 15[/tex].
This mean, the same slope
The equation is the calculated using:
[tex]y - y_1 = m(x - x_2)[/tex]
This gives:
[tex]y - (-1) = -\frac{2}{5}(x - 2)[/tex]
[tex]y +1 = -\frac{2}{5}x +\frac{2}{5}*2[/tex]
[tex]y +1 = -\frac{2}{5}x +\frac{4}{5}[/tex]
[tex]y = -\frac{2}{5}x +\frac{4}{5}-1[/tex]
Take LCM
[tex]y = -\frac{2}{5}x +\frac{4-5}{5}[/tex]
[tex]y = -\frac{2}{5}x -\frac{1}{5}[/tex]
i.e.
[tex]y = -2/3x -1/5[/tex]

The vertical line graph shows how often each number on a standard dice comes up. What percentage of rolls were a 6?
Answer:
21%
Step-by-step explanation:
Out of the 25 + 9 + 12 + 21 + 12 + 21 = 100 total rolls, 6 came up 21 times so the percentage is 21/100 = 21%.

Maria is making 2 liters of cherry lemonade, 5 deciliters of lime lemonade, and 2,500 milliliters of strawberry lemonade for a party. After the party was over, she still had a total of 1.3 liters of lemonade left. How many liters of lemonade were consumed during the party? Enter only the number. Do not include units.
Answer:
3.2 liters were consumed during the party
There are a total of 2000+500+2500=5000 millileters of lemonade at the beginning.
Now there is 1.3 liters left, 5000-1300=3700milliliters=3.7 liters of lemonade is consumed during the party

Answer:25 hours
Step-by-step explanation:
Use the Remainder Theorem to evaluate f(10) for:
f(x) = 2x^3 – 14x^2 - 56x - 40
Step-by-step explanation:
Since we are told that 10 is a zero,
(x−10) must be a factor:
F(x)=2x3−14x2−56x−40
F(x)=(x−10) (2x2+6x+4)
F(x)=2(x−10)(x2+3x+2)
F(x)=2(x−10)(x+2)(x+1)
So the other two zeros are
x = -2 and x= −1
10. The radius of a small wading pool is 3 feet. What is the circumference of this pool?
Answer:
18.85
Step-by-step explanation:
C=2πr=2·π·3≈18.84956
The circumference of this pool is 6π feet.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
Given:
The radius of a small wading pool is 3 feet.
r = 3 feet
And the pool is circular.
So,
circumference of circle = 2πr
Circumference of circle = 2π(3)
Circumference of circle = 6π feet
Therefore, 6π feet is the circumference of the pool.

More than 75% of Americans answer yes when asked, "Do you favor cracking down against illegal gun sales?" but more than 75% say no when asked, "Would you favor a law giving police the power to decide who may own a firearm?"
a. Which statistic would someone who opposes gun control prefer to quote?
b. Explain what is wrong with the wording of each of these statements.
Step-by-step explanation:
Consider the case "Gun control"
(a). The second option,
"Would you favor a law giving police the power to decide who may own a firearm?"
is more favourable question to be asked for someone who opposes gun control.
Because it is expected that most americans would answer that they opposes that giving the police so much power and would likely to oppose Gun Control.
(b). How a Survey question is worded affects the result. Advocates who can afford to sponsor their own surveys can shape the result to try to demostrate support for their position.
Gun Control advocates may phrase a question
"Do you favour cracking down against illegal gun sales?"
While gun control opposition would ask
"Would you favour or oppose alaw giving the police the power to decide who may or may not own a firearm?"
Both question could result in both side of the issue appearing to having the majority of the people supporting their position. In this example a public opinion seems to divide into minorities at the 2 extremes, some favoring a ban on all guns others oppose any Gun COntrol. and a large middle mass that, presumably, favours keeping guns out of the hands of "Bad" people while letting "Good" people have guns.
The complexity of public opinion can be hard to recognize when our information comes from surveys sponsored by advocates who word questions to produce the results they desire.

Mira's six test scores are given. What is the
positive difference between the mean of the
scores and the median of the scores?
86, 72, 92, 62, 99, 93
Answer:
First, we need to find the mean and median of the scores.
Mean:
86+72+92+62+99+93=504
There are 6 test scores, so:
504 ÷ 6 = 84
Median:
62, 72, 86, 92, 93, 99
86 + 92 = 172
172 ÷ 2 = 86
The answer would be:
Mean: 84
Median: 86

Rewrite this division expression as an equivalent multiplication expression 5/8 ÷ 2/3
Answer:
The equivalent multiplication expression is [tex]\frac{5}{8} \times \frac{3}{2}[/tex]
Step-by-step explanation:
Division of fractions:
A division of fractions is the same as the multiplication of the numerator by the inverse of the denominator.
5/8 ÷ 2/3
So numerator is 5/8, denominator is 2/3
[tex]\frac{\frac{5}{8}}{\frac{2}{3}} = \frac{5}{8} \times \frac{3}{2}[/tex]
The equivalent multiplication expression is [tex]\frac{5}{8} \times \frac{3}{2}[/tex]
