Answer:
Step-by-step explanation:
y = (x² - 8x) + 10
Complete the square
coefficient of the x term: -8
divide it in half: -4
square it: (-4)² = 4²
use 4² to complete the square and keep the equation balanced:
y = (x²-8x + 4²) - 4² + 10
y = (x-4)² - 6
Answer:
y = (x - 4)² - 6
Step-by-step explanation:
use the 'completing the square' method:
x² - 8x + 10 = 0
x² - 8x + 16 = -10 + 16
(x - 4)² = 6
y = (x - 4)² - 6

100-20=80
A local ice cream store wanted to see if there was a linear relationship between average temperature on any given day and their ice cream sales. After recording sales and temperatures for 15 randomly selected days they calculated b1 to be equal to 1.24 and a standard error of b1 to be equal to 2.59. Using the appropriate equation, calculate the test statistic is to test if there is a linear relationship between these two variables. Round to two decimal places as necessary. 0.48.
Answer:
the test statistic is 0.48
Step-by-step explanation:
Given that;
sample size n = 15
slope of regression b1 = 1.24
Standard of error SE = 2.59
now,
The hypothesis;
Null hypothesis H₀ : B1 = 0
Alternative hypothesis H₁ : B1 ≠ 0
If there is significant relation between variable x and dependent variable y, the slope will not be equal to zero.
Test Statistic
t = b1 / S.E
we substitute
t = 1.24 / 2.59
t = 0.4787 ≈ 0.48
the test statistic is 0.48

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
How long is the segment from (-5,2) to (5,-8)
Answer:
[tex]\boxed{\textsf{ The lenght of segment is \textbf{ 10}$\sqrt{\textbf{2}} $ \textbf{ units }.}}[/tex]
Step-by-step explanation:
We need to find the lenght of the segment drawn from (-5,2) to (5,-8) . Basically here we need to find the distance between the two points .
Here we can use Distance Formula , which is used to find the distance between two points .
[tex]\rule{200}2[/tex]
★ Distance Formula :-
If we need to find the distance between two points say , [tex]\sf ( x_1,y_1 ) \:\:\:\: \& \:\:\:\: ( x_2,y_2) [/tex] , then we can find out the distance as ,
[tex]\boxed{\boxed{ \sf Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2 } }}[/tex]
[tex]\rule{200}2[/tex]
Put on the respective values ,
[tex]\sf\implies Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2 } \\\\\sf\implies Distance =\sqrt{ ( -5-5)^2+(2+8)^2 }\\\\\sf\implies Distance= \sqrt{ (-10)^2+(10)^2 }\\\\\sf\implies Distance =\sqrt{ 100+100}\\\\\sf\implies Distance =\sqrt{200}\\\\\sf\implies Distance =\sqrt{2\times 10\times 10}\\\\\sf\implies \boxed{\pink{\frak{ Distance = 10\sqrt{2} \:\; units }}}[/tex]
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.
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]

f(x)=-5x^2+4x-9 g(x)=8x^2-3x-4 find (f+g)(x)
Given:
The functions are
[tex]f(x)=-5x^2+4x-9[/tex]
[tex]g(x)=8x^2-3x-4[/tex]
To find:
The value of (f+g)(x).
Solution:
We know that,
[tex](f+g)(x)=f(x)+g(x)[/tex]
Putting the given functions, we get
[tex](f+g)(x)=-5x^2+4x-9+8x^2-3x-4[/tex]
On combining like terms, we get
[tex](f+g)(x)=(-5x^2+8x^2)+(4x-3x)+(-9-4)[/tex]
[tex](f+g)(x)=3x^2+x-13[/tex]
Therefore, the required function is [tex](f+g)(x)=3x^2+x-13[/tex].

Each day after school, Chelsey runs 2.8 miles farther than Kyle.
Part A. Write an equation that represents the number of miles Chelsey runs, c, compared with Kyle, k.
plzz help
Part B. If Kyle runs 4 miles, how many miles does Chelsey run?
Answer:
6.8 miles
Step-by-step explanation:
First, create the equation representing Chelsey's miles compared to Kyle's:
c = k + 2.8
Next, find how many miles Chelsey runs if Kyle runs 4 miles.
Plug in 4 as k into the equation:
c = k + 2.8
c = 4 + 2.8
c = 6.8
So, Chelsey runs 6.8 miles
Answer:
Question :-Each day after school, Chelsey runs 2.8 miles farther than Kyle.
Part A. Write an equation that represents the number of miles Chelsey runs, c, compared with Kyle, k.
plzz help
Part B. If Kyle runs 4 miles, how many miles does Chelsey run?
Solution :-Let the miles walk by Chelesy be x
Now,
x = 4 + 2.8
x = 6.8 miles
Therefore,
x = Kyle's mile walked + 2.86.8 miles[tex] \\ [/tex]

Step-by-step explanation:
just count the blocks!
We should seperate the shape into 2 rectangles.
For the 1st one, we should find the volume by multiplying 2 by 3 by 4
This equals 24 cubic units
The 2nd shape's volume is found by 2 by 5 by 4
This equals 40 cubic units
Now we add the 2 volumes to equal 64 cubic units
