which expression is equivalent to 1/2(2n+6)
Answers
Answer:
n + 3
Step-by-step explanation:
We need to write the expression equivalent to 1/2 ( 2n + 6) . For that open the brackets and simplify the expression. So that ,
=> 1/2 ( 2n + 6)
=> 1/2 × 2n + 1/2 × 6
=> n + 3
Hence the simplied expression is n + 3.Which is a solution to the equation 10-5y = 20?

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
Answers
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.

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]

Answer:
Ordinal Scale
Step-by-step explanation:
The Ordinal Scale may be described as a type of measurement scale which is mostly used to convey qualitative differences while depicting level of magnitude and rank between the labels. The order of a ordinal Scale matters even though the difference between each cannot be measured. It is mostly employed to convey ideas such as level satisfaction, happiness, performance, grade and so on. For the categoroea given above :
Excellent represents the peak ; then Good, followed by Average, then, Below Average, and lastly Poor.

Answers
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

9514 1404 393
Answer:
32 pounds
Step-by-step explanation:
Let 'a' represent the number of pounds of Type A coffee used. Then the number of pounds of Type B coffee in the mix is 2a, and the total cost of the mix is ...
4.35a +5.80(2a) = 510.40
15.95a = 510.40 . . . . collect terms
a = 32 . . . . . . . . . . . divide by 15.95
Number of pounds of type A coffee: 32.

O B. f(x) = 4•(3)^x
O C. f(x) = 3•(4)^x
D. f(x) = 4•(12)^x
Answers
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]
