Answer:
a. Only the x-value is given.
Step-by-step explanation:
Taking a look at the graph of both equations, both equations are graphed correctly, because the slope (m) and y-intercept (b) values corresponds of each equation corresponds with what we have on the graph representing each equation.
The solution of two linear equations ought to be in a coordinate pair, (x, y). This means the x-value and it's correaponding y-value of the solution needs to be stated, not just the x-value.
Thus, the correct solution. Of the two linear equations are x = 4, when y = 3.
Solution in coordinate pair form is (4, 3).
Therefore, the statement that describes the error is:
a. Only the x-value is given.
Let A represent reading newspaper and represent watching television
Which statement is true?
Watching television and and reading newspaper are independent events because P(AB) + P(A) and
PBAP(B)
Watching television and reading newspaper are not independent events because P(AB)=P(A) and
P(BA) - P(B)
Watching television and reading newspaper are independent events because P(AB) = P(A) and P(BA) = P(B).
Watching television and reading newspaper are not independent events because P(AB) + P(A) and
P(BA) = P(B)

Answer:
-3/4
Step-by-step explanation:
Answer:
B. 4/3
Step-by-step explanation:
The slope is rise over run or the change in y over the change in x. To find the slope count how many units y increases by then divide that by how many units x increases. In this graph y goes up by 4 and x increases by 3, so 4/3. Another way to find slope is the slope formula which is [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], then plug in any two points and solve them.

Step-by-step explanation:
Sarah has saved 254 pound coins. She puts the pound coins into bags.
There are 20 pound coins in each full bag of coins. Sarah is going to take all her full bags of coins to the bank.
She can only take up to 5 full bags of coins to the bank each day.
Sarah wants to go to the bank on as few days as possible.
On how many days will Sarah need to go to the bank?
Answer:
Step-by-step explanation:
So for the fewest days it would be 3 days. The reason for that is because she has 254 pound coins. And she can inly take 5 bags to the bank a day, all of those 5 bags have 100 pound coins in them. If she take 2 days and get 200 pound coins to the bank. Then on the third day she would only have to bring three bags. So your answer for the fewest days possible is three days!

. Part A: Under a dilation of scale factor 3 centered at the origin, AB becomes A'B'. Determine the coordinates of A'B' and sketch A'B' on the graph. 1 Part B: Under a dilation of scale factor - centered at the origin, AB becomes DC. Determine the coordinates of DC and sketch DC on the graph.
Answer:
Step-by-step explanation:
Part A.
Coordinates of A and B are,
A(-2, 2) and B(3, 2)
Rule for dilation of a point (x, y) by a scale factor k about the origin,
(x, y) → (kx, ky)
If the points A and B are dilated by a scale factor 3, image points will be,
A(-2, 2) → A'(-6, 6)
B(3, 2) → B'(9, 6)
Part B.
Following the same rule of dilation about the origin by a scale factor of [tex]\frac{1}{2}[/tex] about the origin,
A(-2, 2) → D(-1, 1)
B(3, 2) → [tex]C(\frac{3}{2},1)[/tex]

question: Your mass on earth is 50 kilograms. What is your mass on the moon?
Answer:
No matter if you are on Earth, the moon or just chilling in space, your mass does not change. But your weight depends on the gravity force; you would weigh less on the moon than on Earth, and in space you would weigh almost nothing at all. Where ever you are, your mass will always stay the same.
Answer:
50 kilograms
Step-by-step explanation:
Mass never changes, and is constant everywhere. The weight is what changes. If you weigh 50 kg on Earth, you'll weigh 50 kg everywhere else in the universe. That's because the amount of matter in you cannot change.
The speed at which you can log into a website through a smartphone is an important quality characteristic of that website. In a recent test, the mean time to log into the JetBlue Airways website through a smartphone was 4.237 seconds. Suppose that the download time is normally distributed, with a standard deviation of 1.3 seconds. What is the probability that the download time is:
A. Less than 2 seconds?
B. Between 1.5 and 2.5 seconds
C. Above 1.8 seconds
D. 99% of the download times are slower (higher) than how many seconds?
E. 95% of the download times are between what two values, symmetrically distributed around the mean?
F. Suppose that the download times are uniformly distributed between 1 and 9 seconds. What are your answers to A through C?
Answer:
A.) 0.0426
B) 0.073121
C.) 0.96958
D.) 1.2 seconds
E.) 1.689 < x < 6.785
Step-by-step explanation:
Given a normal distribution :
Mean download time (m) = 4.237 seconds
Standard deviation (s) = 1.3 seconds
A.) Probability that download time is less than 2 seconds :
P(x < 2)
Obtain standardized score (Z) :
Z = (x - m) / s
Z = (2 - 4.237) / 1.3
Z = −1.720769
P(Z < - 1.7208) = 0.0426 (Z probability calculator)
B.) Between 1.5 and 2.5 seconds :
1.5 < z < 2.5
((x - m) / s) < z <((x - m) / s)
((1.5 - 4.237) / 1.3) < z < ((2.5 - 4.237) / 1.3)
−2.105384 < z < −1.336153
P(Z < - 2.10538) = 0.017629
P(Z −1.336153) = 0.09075
0.09075 - 0.017629 = 0.073121
C.) Above 1.8 seconds
P(x > 1.8)
Obtain standardized score (Z) :
Z = (x - m) / s
Z = (1.8 - 4.237) / 1.3
Z = −1.874615
P(Z > −1.874615) = 0.96958 (Z probability calculator)
D.) 99% of the download times are slower (higher) than how many seconds?
P(Z > x) = 99% = 0.99
Z value corresponds to -2.326
Z = (x - m) / s
-2.326 = (x - 4.237) / 1.3
-2.326 * 1.3 = x - 4.237
−3.0238 = x - 4.237
−3.0238 + 4.237 = x
x = 1.2132
x = 1.2 seconds
E. 95% of the download times are between what two values, symmetrically distributed around the mean?
For symmetric distribution around the mean ;
P(-Z<x<Z) = 0.95
Corresponds to a z value of 1.96
-1.96 * 1.3 = x - 4.237
-2.548 = x - 4.237
x = - 2.548 + 4.237
x = 1.689
1.96 * 1.3 = x - 4.237
2.548 = x - 4.237
x = 2.548 + 4.237
x = 6.785
1.689 < x < 6.785

The polynomial p is a function of x. The graph of p has four zeros at -4, -2/3, 0, and 9
Select all the expression that could represent p.
A

B
3x(x – 4) (x + 3)(x +9)
с

D
- x(x + 4) (x + })(x – 9)
E

The only expression of that can represent polynomial p as a function on a graph having four zeros at -4, -2/3, 0, and 9 is: A. [tex]\mathbf{-3x(x + 4)(3x + 2)(x - 9)}[/tex]
Given the four zeros of the graph of p are at:
-4, -2/3, 0, and 9From the options given, the expression in option A will represent a function of a polynomial p with zeros at -4, -2/3, 0, and 9.
Here's why:
[tex]-3x(x + 4)(3x + 2)(x - 9)[/tex] (option A)
Therefore are four factors in the polynomial above which are:
[tex]3x\\\\(x + 4)\\\\(2x - 3), $ and\\\\(x -9)[/tex]
The zeros of polynomial p will be the following:
[tex]3x = 0\\\\x = \frac{0}{3} \\\\\mathbf{x = 0}[/tex]
[tex](x + 4) = 0\\\\\mathbf{x = -4}[/tex]
[tex](3x + 2) = 0\\\\3x = -2\\\\\mathbf{x =-\frac{2}{3}}[/tex]
[tex](x -9) = 0\\\\\mathbf{x = 9}[/tex]
Therefore, the only expression of that can represent polynomial p as a function on a graph having four zeros at -4, -2/3, 0, and 9 is: A. [tex]\mathbf{-3x(x + 4)(3x + 2)(x - 9)}[/tex]

A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
O 2y = 16x +14
O y = 8x - 7
O y = -8x + 7
O 2y = -16x - 14
The other equation could be y = 8x - 7
How to determine the other equation?The first equation is given as:
y = 8x + 7
For the system of equation to have no solution, then the equations in the system would have different constant values.
Take for instance:
y = 8x + b
Where:
b is a constant not equal to 7
From the options, we have:
y = 8x - 7
Notice that -7 and 7 are not the same
Hence, the other equation could be y = 8x - 7

Jim walks 6/7 of a mile every day. Russell walks 1/4 of a mile. How much farther does Jim work than Russell.
Answer:
Jim walked 17/28 for miles than Russel
Step-by-step explanation:
First you turn 6/7 and 1/4 to have the same denominators. In that case you find the least common multiple which is 28.
7: 7, 14, 21, 28
4: 4, 8, 12, 16, 20, 24, 28
Next you multiply the top and the bottom of your fraction my the factor you used to get 28 for your denominator
6/7 x 4/4 = 24/28
1/4 x 7/7 = 7/28
Lastly, you subtract the products you got.
24/28 - 7/28 = 17/28
