Answer:
X=0
Y=0
Y=x
Y=-x
I need to know what the x and y intercepts are for these problems. if you could show work i would appreciate it.
1. f(x)=4x−8
2. f(x)=1/2x+2
3. f(x)=x^2-16
Answer:
1.
x = (2,0)
y = (0,-8)
2.
x = (-2,0)
y = ( 0, 2)
3.
x = ( 4,0)
y = ( 0, -16)
Step-by-step explanation:
aIll do one equation as an example
f(x) = 4x -8
y = 4x - 8
since its an intercept you know the x, for the y intercept will be zero and vice versa. Its like this cause its on the axis.
So you only need to figure out the y for the y intercept and the x for the x intercept.
- 4x + y = -8
after changing the equation to standar form you then ignore the x base so, 4x to get the y intercept.
- 4x + y = -8 becomes y = - 8 then you add the 0 for the coordinate
y = -8 becomes (0,-8)
f(x) = 4x -8
y = 4x - 8
- 4x + y = -8
y = - 8
(0,-8)
f(x) = 4x -8
y = 4x - 8
- 4x + y = -8
-4x = -8
x = 2

Use the empirical rule (68-95-99.7) to determine if the following maximum daily rainfall totals could be considered to be normally distributed. (16 points) 1.1, 1.2, 1.5, 1.55, 1.71, 1.75, 1.9, 1.94, 1.99, 2.0, 2.05, 2.08, 2.12, 2.18, 2.2, 2.25, 2.36, 2.5, 2.61, 2.81, 2.88, 2.95, 3.0, 3.03, 3.07, 3.16, 3.25, 3.62.
Answer:
Step-by-step explanation:
Given that:
The number of observations (n) = 28
The mean [tex]\overline x[/tex] is the addition of all the given numbers divided by the total number of observations = 64.76/28
[tex]\overline x[/tex] = 2.31
The standard deviation s = 0.65
At 68%; the empirical rule falls between:
= [tex]\overline x \pm s[/tex]
= 2.31 ± 0,65
= ( 2.31 - 0.65, 2.31 + 0.65)
= (1.66 , 2.96)
From the parameters given:
4 values are < 1.66 and 6 values are > 2.96
Thus, the percentage covered = (28 - (6+4))/28 × 100
= (28 - 10) / 28 × 100
= (18/28) × 100
= 64.29%
Hence, this satisfies the normal distribution
At 95; the empirical rule falls between:
= [tex]\overline x \pm 2 s[/tex]
= 2.31 ± 2(0.65)
= 2.31 ± 1.30
= ( 2.31 - 1.30, 2.31 + 1.30)
= (1.01 , 3.61)
From the parameters given:
0 values are < 1.01 and 1 values are > 3.61
Thus, the percentage covered = (28 - (1+0))/28 × 100
= (28 - 1) / 28 × 100
= (27/28) × 100
= 96.43%
Hence, this satisfies the normal distribution
At 99.7; the empirical rule falls between:
= [tex]\overline x \pm 3 s[/tex]
= 2.31 ± 3(0.65)
= 2.31 ± 1.95
= ( 2.31 - 1.95, 2.31 + 1.95)
= (0.36 , 4.26)
From the parameters given:
0 values are < 0.36 and 0 values are > 4.26
Thus, the percentage covered = (28 - (0+0))/28 × 100
= (28 - 0) / 28 × 100
= (28/28) × 100
=100%
Hence, this satisfies the normal distribution and the maximum daily rainfall totals could be considered to be normally distributed.

Answer:
I think it's B
Step-by-step explanation:
At the beginning of a science experiment, Betty had 40 milliliters of solution. During the experiment, the change in the volume of the solution was – 11 milliliters. What is the final volume of the solution? milliliters
Answer:
[tex]Final\ Volume = 29ml[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Solution = 40ml[/tex]
[tex]Change = -11ml[/tex]
Required:
Determine the final volume of the solution
The final volume is calculated as thus:
[tex]Final\ Volume = Initial\ Volume + Change[/tex]
Substitute values for Initial Volume and Change.
This gives
[tex]Final\ Volume = 40ml - 11ml[/tex]
Subtract 11 from 40
[tex]Final\ Volume = 29ml[/tex]
Hence, Betty had 29 ml of the solution
dollar markdowns represent price increases to the original selling price.
Answer:
false
Step-by-step explanation:
The statement being made is false. Dollar markdowns actually represent the difference in price that exists between the original price of the product and the current price that the item is selling for. This is what happens when a store places a discount on an item or places a sale on it. Dollar Markdown is the actual difference in dollar/currency value while Markdown percentage is the difference in percentage with regards to the original price.

What percent of students prefer burgers?
Answer:
40 (without the percent sign because the question doesn’t want you to put it)
Step-by-step explanation:
This is a very reasonable diagram because the 216˚ plus the 144˚ equal 360˚, which is sensible because a circle is 360˚ (degrees). So, you can just do 144 divided by 360 to find the percent of the circle, which equals 0.4, and 0.4 as a percent is 40%. But the question doen’t want to you to put the percent sign. So the answer is just 40.
At the grocery store, peaches cost $2.60 per pound. Grace bought 36.8 ounces of peaches.
There are 16 ounces in 1 pound. How much did Grace spend on peaches?
Answer:
the total would be $7.00
Step-by-step explanation:
36.8 ounces = 2.3 pounds so first you add up how much it costs for 2 pounds and you get 5.20 after that you figure out how much and ounce is and that's 60 cents you add that all up and you get $7.00 (I don't know if I'm right it's been a while since I've done math like this hope it helps)

A baker’s dozen includes 13 rolls for the price of a dozen rolls. How much money is saved by buying a baker’s dozen instead of 13 individual rolls?
Answer:
$0.60
Step-by-step explanation:
If you purchase 6 rolls, you pay $3.60
Each roll is $0.60.
If you purchase 13 individual rolls, you pay
13 x 0.6 = $7.80
But if you purchase the Baker's dozen, you pay only $7.20, so you save $0.60
7.80 - 7.20 = 0.60
Hope this helps! :)

a taxi company charges an initial fee of $1.95, plus $1.60 per mile driven. Shelly has $22.00 to spend on a taxi ride. Which inequality represents the number of miles , m, that shelly can ride in a taxi?
Step-by-step explanation:
$1.95 initial fee.
$1.60 per mile driven.
$22.00 spend limit.
22.00 - 1.95 = 20.05She has $20.05 after paying the initial fee.
Shelly has $20.05 for miles traveled.
20.05 ÷ 1.60 = 12.53125She can travel approximately 12.5 miles.
[$22.00 - $1.95] ÷ $1.60 = m

28.3
Step-by-step explanation:
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
so
(x+34)*x=42^2
x^2+34x=1764
x^2+34x-1764=0
D=b^2-4ac
D=34^2-4*1*(-1764)
D=1156+7056
D= 8212
x=(-b+√D)/2a=(-34+90.6)/2=56.6/2=28.3
Answer:

The length of a rectangle is four times its width.
If the perimeter of the rectangle is 100 in, find its length and width.
Answer:
Length: 40 inches
Width: 10 inches
Step-by-step explanation:
Let [tex]x =[/tex] width of the rectangle.
From the information "length of a rectangle is four times its width", we can express the length as:
Length = [tex]4x[/tex]
- - - -
Perimeter = [tex]2l+2w[/tex] (formula for perimeter of rectangle)
[tex]100=2(4x)+2(x)[/tex]
[tex]100=8x+2x[/tex]
[tex]10x=100[/tex] (combine like terms)
[tex]x=10[/tex] inches
∴ The width of the rectangle is 10 inches.
To find the length of the rectangle, we can use substitution:
Length = [tex]4x[/tex]
[tex]=4(10)[/tex]
[tex]=40[/tex] inches
∴ The length of the rectangle is 40 inches.
Hope this helps :)
Which of the following points is not coplanar with polnis C, D and E?
Answer: Point R
===================================================
Explanation:
The term "coplanar" means "points that are in the same plane".
Points A, S and U are all in the base plane. Think of this as the floor of the pyramid, so to speak. These three points are with C, D, and E, which are also on the base plane or floor plane. So we can say that all of these points are coplanar.
In contrast, point R is not on the floor plane. It's higher up. So that's why R is not coplanar with points C,D,E.
