Ethan tired to write an equation of the linear table but made a mistake. Need help it’s due today!?!?
Answers
Given:
The table for a linear function.
To find:
The equation of the linear function.
Solution:
If a linear function passes through two points, then the equation of linear function is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Consider any two points from the given table. Let the two points are (2,-2) and (4,0). So, the equation of linear function is
[tex]y-(-2)=\dfrac{0-(-2)}{4-2}(x-2)[/tex]
[tex]y+2=\dfrac{2}{2}(x-2)[/tex]
[tex]y+2=x-2[/tex]
Subtracting 2 from both sides.
[tex]y+2-2=x-2-2[/tex]
[tex]y=x-4[/tex]
So, Ethan 's made a mistake. The sign between x and 4 must be negative but in Ethan's equation it is a positive sign, which is not correct.
Therefore, the required linear equation is [tex]y=x-4[/tex].

Answer:
[tex]s = 0.0394[/tex]
Step-by-step explanation:
Given:
0.612 0.523 0.606 0.631 0.584 0.592 0.644 0.597 0.639 0.607 0.564 0.673
Required
Calculate the sample standard deviation
First, calculate the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{0.612 +0.523 +0.606 +0.631+ 0.584 + 0.592+ 0.644 +0.597 +0.639 +0.607 +0.564+ 0.673}{12}[/tex]
[tex]\bar x = \frac{7.272}{12}[/tex]
[tex]\bar x = 0.606[/tex]
The sample standard deviation is then calculated using:
[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
[tex]\sum (x - \bar x)^2 = (0.612 -0.606)^2+(0.523 -0.606)^2+(0.606 -0.606)^2+(0.631 -0.606)^2+(0.584 -0.606)^2+(0.592 -0.606)^2+(0.644 -0.606)^2+(0.597 -0.606)^2+(0.639 -0.606)^2+(0.607 -0.606)^2+(0.564 -0.606)^2+(0.673 -0.606)^2[/tex]
[tex]\sum (x - \bar x)^2 = 0.017098[/tex]
So, we have:
[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
[tex]s = \sqrt{\frac{0.017098}{12-1}}[/tex]
[tex]s = \sqrt{\frac{0.017098}{11}}[/tex]
[tex]s = \sqrt{0.00155436363}[/tex]
[tex]s = 0.0394[/tex] -- approximated

Answers
Answer:
A.
Step-by-step explanation:
We have the expression [tex]\sqrt{x+4} -3=2[/tex] and are asked which is the first step to solve it.
When doing equations, you always want to isolate x, now since x is stuck in a square root, we need to first get rid of the numbers outside the root. So -3, we would need to add three to both sides first. This step crosses out all other answers and leave us with A.

Answers
Answer:
1 3/8 inches
Step-by-step explanation:
Total Length after adding 2 meteors of equal length = 16 inches
Let the length of the added meteor = x
To obtain the total length, we sum of each meteror multiplied by its frequency is obtained ;
(2/8)(1)+(3/8)(3)+(4/8)(2)+(6/8)(2)+(10/8)(1)+(11/8)(2)+(14/8)(2)+(15/8)(1) + 2x = 16
13.25 + 2x = 16
13.25 + 2x = 16
2x = 16 - 13.25
2x = 2.75
x = 1.375
1.375 = 1 3/8

here,
Let the number be x,
According to the question,
The product of a number and -3 increased by 8 is no less than 35.
So,
-3x + 8 ≥ 35

Sally collected 32 coins. The ratio of Sally’s coins to Bill’s coins is 4 : 7. If Sally and Bill each double the number of coins they have now, what is the ratio of Sally’s coins to Bill’s coins?
Answers
Answer:
64 S
----
112 B
Step-by-step explanation:
The number of coins Sally and Bill will be 64 and 112 and the ratio will remain the same.
What is the ratio?
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that Salley collected 32 coins, the ratio of Sally’s coins to Bill’s coins is 4: 7, and Sally and Bill each double the number of coins they have now.
Suppose the number of coins that Sally and Bill will be 4x and 7x respectively.
If Sally has the 32 coins and if she doubles the coins she has 64.
4x = 64
x =16
Sally’s coins,
4x = 4 × 16 =64
Bill’s coins,
7x =7× 16 = 112
Thus, the number of coins Sally and Bill will be 64 and 112 and the ratio will remain the same.
