Write an equation in the form y = mx + b
Answer:
y=-2x+8
Step-by-step explanation:
So I select 2 points:
(0,8) and (4,0)
so then I find the slope.
m = [tex]\frac{8-0}{0-4} \\=\frac{8}{-4} \\=\frac{2}{-1} \\=-2[/tex]
m = -2
Then the b (y-intercept) is 8, so equation is:
y=-2x+8

The manufacturer of a low-calorie dairy drink wishes to compare the taste appeal of a new formula (formula B) with that of the standard formula (formula A). Each of four judges is given three glasses in random order, two containing formula A and the other containing formula B. Each judge is asked to state which glass he or she most enjoyed. Suppose that the two formulas are equally attractive. Let Y be the number of judges stating a preference for the new formula. a Find the probability function for Y . b What is the probability that at least three of the four judges state a preference for the new formula
Answer:
a) [tex]P_y = \frac{4}{y} * \frac{1}{3}^y * \frac{2}{3}^{4-y}[/tex]
b) 0.033
Step-by-step explanation:
Let Y represents the number of judges preferring a formula.
There are total four judges and each judge can select either A or B
n = 4, p = 1/3
a) The probability function is
[tex]P_y = \frac{4}{y} * \frac{1}{3}^y * \frac{2}{3}^{4-y}[/tex]
b)
Substituting the value of y -3 in above equation, we get -
[tex]P_3 = \frac{4}{3} * \frac{1}{3}^3 * \frac{2}{3}^{4-3}\\= \frac{4}{3} * 0.037 * 0.67\\= 0.033[/tex]

The graph shows a proportional relationship. Which equation matches the graph.
A. y = 1/5x
B. y = x
C. y = 15x
D. y = 5x
Answer:
D
Step-by-step explanation:
When x = 1, y = 5
When x = 3, y = 15
So, using this, find the slope.
(15 - 5) / (3 - 1) = 10 / 2 = 5
For every x, y increases by 5.
So, y = 5x, or D
Answer:
D
Step-by-step explanation:
5x
what does it mean to be a solution to an inequality
Answer:
Rule 1. Adding/subtracting the same number on both sides.
Example: The inequality x-2>5 has the same answer as the inequality x > 7.
Rule 2. Switching sides and changing the orientation of the inequality sign.
Example: The inequality 5-x> 4 has the same solutions as the inequality 4 < 5 - x.

We need a rock garden with a perimeter of 12 feet and an area of 8 square feet
Length: Feet
Width: Feet
Answer:
Length: 4 feet
Width: 2 feet
Step-by-step explanation:
The only possibilities that could get an area of 8 feet are 4 x 2 and 8 x 1
However, it has to be 4 x 2 because the 8 x 1 dimension won't have a perimeter of 12 feet.
The dimensions of 4 x 2 will have an area of 8 square feet, since 4(2) = 8
It will also have a perimeter of 12 feet because 4 + 4 + 2 + 2 = 12
So, the length is 4 feet and the width is 2 feet

Sylvan drove 128.6 km each day for 8 days. He drove 44.3 km each day for 12 days. What was the total distance Sylvan drove?
Answer:
If x and y are the hours she drove at the different rates, then:
x+y=5
80x+100y=440
-------
80x+100y=440
80x+80y=400
20y=40
y=2
x=3
She drove 3 hours at 80 kmh and 2 hours at 100kmh!!!!!!!

A college student takes the same number of credits each semester. She had 12 credits when she started, and after 6
semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?
Answer:
x = 14
Step-by-step explanation:
Credits = 12 Semesters = 6 Total Credits = 96
6x = 96 - 12
6x = 84
Divide 6x = 84 by 6.
x = 14
[tex]\frac{96 credits-12 credits}{6 semesters} =\frac{84 credits}{6 credits} = \frac{14 credits}{1 semester}[/tex]
does 5+4=8 and does 1+1=2
Answer:
5 + 4 = 8 (False)
1 + 1 = 2 (True)
Step-by-step explanation:
First Case:
5+4=8
No this is not correct as when 5 is added to 4 then the result should be - (1+1+1+1+1) + (1+1+1+1)
= 1 + 1 + 1 + 1 + 1 + 1 + 1 +1 +1
= 9
So this is not correct.
Second Case:
1 + 1 = 2
Yes this is correct when 1 and 1 are added for two times it results in 2.

Jayden has $10 in a savings account. The interest rate is 5%, compounded annually.
To the nearest cent, how much interest will he earn in 2 years?
$
Submit
Answer:
$1
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 10 × 0.05 × 2 = 1
I = $ 1.00
The simple interest accumulated
on a principal of $ 10.00
at a rate of 5% per year
for 2 years is $ 1.00.
