Answer:
The answer is (2+7)*2
Step-by-step explanation:
as you can see the you have to add the bottom to the top then multiply the answer by the height to what i did was i seen if there was anything that can add to 7 with the number 2 and 5 was so put 5 at the top and multiply 7 times two you get 14

Sam is interested in buying a TV. At Walmart, the TV is regularly prices at $599.99 and is on sale for 20% off the regular price. At Best Buy, the same TV is regularly prices at $899.99 and is on sale for 30%off the regular price.
What is the difference in the sale price of the TV between these two stores?
Show your work.
Answer:
If 30% of 599.99 is 197.99 and 30% of 899.99 is 269.99 then you subtract 269.99-197.99= $72

Which equation is equivalent to the formula below?
y = a(x-h)^2+k
Answer:
a=y-k/(x-h)^2
Write the equation for the line
Answer:
y=4x+3
Step-by-step explanation:
The slope is positive 4 and the y intercept is 3
Answer:
y = 4x + 3
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept
The slope is how much units it goes up/down while how much units it goes left/right from one point to the other. So two points we'll use for reference is (-1, -1) and (0, 3). You want to make sure the points u choose are whole numbers cause they're easier to tell. So the distance between those 2 points if it goes to the right once and goes up 4 units. Left/right is x and up/down is y, y/x is how u write the slope. So it's 4/1 which is just 4
The y-intercept is just where the line intercepts on the y-axis. The line goes through the point 3 on the y-axis, so it's 3
Input the numbers in the equation and it's y = 4x + 3

Answer:
a) 6.1 feet
b) 12.6 feet
Step-by-step explanation:
Using trigonometric ratios we know that:
[tex]sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}[/tex]
AKA SohCahToa.
To find the height, we will use sine.
[tex]sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14[/tex]
To find the length we will use cosine.
[tex]cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6[/tex]

The answer is D
Step-by-step explanation:
Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary
This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.
You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other
Hope this helped you!!!

According to a recent survey, 81 percent of adults in a certain state have graduated from high school. If 15 adults from the state are selected at random, what is the probability that 5 of them have not graduated from high school?
Answer:
0.090401
Step-by-step explanation:
Given that:
Probability of graduate = 81% = 0.81
P( not graduate) = p = (1 - 0.81) = 0.19
1 - p = 0.81
Using binomial distribution :
P(x = x) = nCx * p^x * 1-p^(n-x)
n = 15 ; x =5
P(x = 5) = 15C5 * 0.19^5 * 0.81^(15 - 5)
P(x = 5) = 15C5 * 0.19^5 * 0.81^10
P(x = 5) = 3003 * 0.0002476099 * 0.12157665459056928801
P(x = 5) = 0.090401
Answer:
D: (15/5) (0.19)^5 (0.81)^10

Which of these strategies would eliminate a variable in the system of equations?2x−5y=13
−3x+2y=13
A. Multiply the top equation by 2, multiply the bottom equation by 3, then add the equations.
B. Subtract the bottom equation from the top equation
C. Multiply the top equation by 3, multiply the bottom equation by 2, then add the equations.
Answer:
We conclude that when we multiply the top equation by 3, multiply the bottom equation by 2, then add the equations, it would eliminate the variable 'x'.
Thus, option (C) is true.
Step-by-step explanation:
Given the system of the equation
2x−5y=13
−3x+2y=13
Multiply the top equation by 33(2x−5y) = 3(13)
6x - 15y = 39
Multiply the bottom equation by 22(−3x+2y) = 2(13)
-6x + 4y = 26
Adding both equations
6x - 15y = 39
+
-6x + 4y = 26
___________
0x - 11y = 65
-11y = 65 ∵ x variable eliminates
Divide both sides by -11
y = -65/11
Therefore, we conclude that when we multiply the top equation by 3, multiply the bottom equation by 2, then add the equations, it would eliminate the variable 'x'.
Thus, option (C) is true.

A real-estate company appraised the market value of 36 homes in Lyttelton and found that the sample mean and standard deviation were $150,000 and $17,000 respectively. The real-estate company also appraised the market value of 45 homes in Aranui and found that the sample mean and standard deviation were $100,000 and $12,000 respectively. Calculate the 90% confidence interval estimate for the population difference in market value between the Lyttelton and Aranui areas .
Solution :
Sample size Sample mean Sample S.D.
Sample 1 [tex]$n_1=36$[/tex] [tex]$\bar{x}_1=150,000$[/tex] [tex]$s_1=17,000$[/tex]
Sample 2 [tex]$n_2=45$[/tex] [tex]$\bar{x}_2=100,000$[/tex] [tex]$s_2=12,000$[/tex]
[tex]$df = \frac{\left(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}\right)^2}{\frac{1}{n_1-1}\left(\frac{s_1^2}{n_1}\right)^2+\frac{1}{n_2-1}\left(\frac{s_2^2}{n_2}\right)^2}$[/tex]
= 60
Therefore, significance level, α = 0.1
Critical value, t* = 1.6706
So, the margin of error, [tex]$t^*=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$[/tex]
= 559.9896
Lower limit, [tex]$(\bar x_1-\bar x_2)-\text{(margin of error)}=44402.0104$[/tex]
Upper limit, [tex]$(\bar x_1-\bar x_2)+\text{(margin of error)}=55597.9896$[/tex]
Therefore 90% C.I. is (44402.0104, 55597.9896) or [tex]$44402.0104 < \mu_1 - \mu_2 < 55597.9896$[/tex]

Betsy buys three lamps and two end tables and pays $520. Her friend Tina buys two lamps
and RETURNS an end table and only pays $20. What do the lamps and end tables cost?
9514 1404 393
Answer:
lamp: $80end table: $140Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.
Find the value of y if the value of x is 2 for each equation and match it with the appropriate result.
2 + y = 5
3x + 2y = 6
2x + y = 6
5x + 3y = 4

Answer:
3, 0, 2, -2
Step-by-step explanation:
Put x=2 into each equation and solve for y.
2 + y = 5
y = 5 -2
y = 3
3x +2y = 6
3·2 +2y = 6
2y = 6 -6 = 0
y = 0
2x +y = 6
2·2 +y = 6
y = 6 -4
y = 2
5x +3y = 4
5·2 +3y = 4
3y = 4 -10 = -6
y = -2
Briefly describe this graph of a Ferris wheel.
A graph has time on the x-axis and height on the y-axis. The graph increases and decreases through 4 cycles.
Answer:
As time increases, the height of the person riding the Ferris wheel goes up and down. The Ferris wheel makes 4 rotations. The highest points on the graph are when the Ferris wheel is at its highest height. The lowest points on the graph are when the Ferris wheel is at the starting position.
Step-by-step explanation:
Answer:
The Ferris wheel makes 4 rotations. The maximum points on the graph represent when the Ferris wheel is at the top, and the minimum points on the graph represent when the Ferris wheel is at the bottom. This is what it said
