For the given equation, what is the step to clear the fractions and what is the result?
O Multiply both sides by 6 to get 4y - 1 = 21.
O Multiply both sides by 18 to get 12y - 3 = 7.
O Multiply both sides by 6 to get 2y - 1 = 7.
Multiply both sides by 12 to get 2y - 1 = 7
Answer:
The first choice
Step-by-step explanation:
Multiplyil by 6 to get 4y - 1 =21

arcAE = 126°
Step-by-step explanation:
Note that arcAD is a diameter therefore arcAD = 180°. And arcAD = arcAE + arcED
Also note that the inscribed angleEAD intercepts the arcED and according to the inscribed angle theorem,
angleEAD = (1/2)arcED
or
arcED = 2×angleEAD = 2×(27°) = 54°
This means that the arcAE is
arcAE = arcAD - arcED
= 180° - 54°
= 126°
[tex]\\ \sf\longmapsto arc \overset{\sim}{ED}=2(<A)=2(27)=54°[/tex]
Now
[tex]\\ \sf\longmapsto arc\overset{\sim}{AE}+arc\overset{\sim}{ED}=180[/tex]
[tex]\\ \sf\longmapsto arcc\overset{\sim}{AE}=180-54=126°[/tex]

Graduates A random sample of the average debt (in dollars) at graduation from 30 of the top 100 public colleges and universities is listed below. Is there sufficient evidence at a _ 0.01 to conclude that the population mean debt at graduation is less than $18,000? Assume s _ 2605

a. State the hypotheses and identify the claim.
b. Find the critical value(s).
c. Compute the test value.
d. Make the decision.
e. Summarize the results
Answer:
H0 : μ = 18000
H1 : μ < 18000 - - - > Claim
Test value = - 3.578
Critical value = ±2.58
There is significant evidence to accept the claim that mean debt at graduation is less than $18000
Step-by-step explanation:
H0 : μ = 18000
H1 : μ < 18000
From the data:
Sample size, n = 30
Sample mean, x = 16298.37
The test statistic :
(16298.37 - 18000) ÷ (2605/sqrt(30))
−1701.63 / 475.60575
= - 3.578
The critical value :
Using the standard normal table;
Critical value at α = 0.01
Critical value = ±2.58
Decison region :
|test statistic | > |Critical value | ; reject H0
|3.578| > |2.58| ; We reject H0 and conclude that Mean debt at graduation is less than $18000

Write the function for the graph.
(1,12)
(0,3)
O A. f(x) = 3•(12)^x
O B. f(x) = 4•(3)^x
O C. f(x) = 3•(4)^x
D. f(x) = 4•(12)^x
Answer:
[tex]f(x) =3 * (4)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1, y_1) = (1,12)[/tex]
[tex](x_2, y_2) = (0,3)[/tex]
Required
The function of the graph (exponential function)
An exponential function is represented as:
[tex]f(x) = ab^x[/tex]
For [tex](x_1, y_1) = (1,12)[/tex], we have:
[tex]12 = a * b^1[/tex]
[tex]12 = a * b[/tex]
[tex]12 = a b[/tex]
For [tex](x_2, y_2) = (0,3)[/tex]
[tex]3 = a * b^0[/tex]
[tex]3 = a * 1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute: [tex]a = 3[/tex] in [tex]12 = a b[/tex]
[tex]12 = 3 * b[/tex]
Divide both sides by 3
[tex]4 = b[/tex]
[tex]b =4[/tex]
So, we have:
[tex]f(x) = ab^x[/tex]
[tex]f(x) =3 * (4)^x[/tex]

The length of a cell phone is 2.2 inches and the width is 4.6 inches. The company
making the cell phone wants to make a new version whose length will be 2.09 inches.
Assuming the side lengths in the new phone are proportional to the old phone, what
will be the width of the new phone?
Answer:
The width of the new phone will be of 4.37 inches.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
In this question:
Length was of 2.2 inches, after the modification is of 2.09 inches.
Width was of 4.6 inches, after the modification is x. So
2.2 - 2.09
4.6 - x
Applying cross multiplication:
[tex]2.2x = 2.09*4.6[/tex]
[tex]x = \frac{2.09*4.6}{2.2}[/tex]
[tex]x = 4.37[/tex]
The width of the new phone will be of 4.37 inches.

An assistant receives a wage of $16.24 per hour this amount is 112% of last year's wage what is the dollar increase in the hourly wage over last year use proportion method
9514 1404 393
Answer:
$1.74
Step-by-step explanation:
The ratio of the increase to this year's wage is ...
12%/112% = x/$16.24
Multiplying by $16.24, we have ...
x = $16.24(12/112) = $1.74
The dollar amount of the wage increase is $1.74.
