Write an algebraic expression for the situation.

An algebraic expression for the situation is _
Answer:
m - 3.2
Step-by-step explanation:
An extensive study of the cost of health care in the U.S. showed that the mean annual spending per Medicare enrollee was $6,883. To investigate the differences across the country, a researcher took a sample of 40 Medicare enrollees in Indianapolis. For the Indianapolis sample, the mean annual Medicare spending was $5,980 and the standard deviation was $2,518. Using a level of significance of 3%, test to see if the mean annual Medicare spending in Indianapolis is lower than the national mean. Interpret your result.
Solution :
Given :
[tex]$\mu = 6883$[/tex]
[tex]$s=2518$[/tex]
n = 40
[tex]$\overline x = 5980$[/tex]
Therefore, determining the null hypothesis and alternate hypothesis is :
[tex]$H_0: \mu = 6883$[/tex]
[tex]$H_a: \mu < 6883$[/tex]
The value of the test statistics is :
[tex]$t=\frac{\overline x - \mu}{s/\sqrt n}$[/tex]
[tex]$t=\frac{5980 - 6883}{2518/\sqrt 40}$[/tex]
[tex]$t \approx -2.27$[/tex]
So, df = n - 1
= 40 - 1
= 39
∴ 0.01 < P < 0.025
If the P value is less than α = 0.03, we reject the null hypothesis. Therefore, we conclude that mean annual Medicare spending in Indianapolis is lower than the national mean.
Using the value of [tex]$\alpha = 0.03$[/tex], the critical value of for the test statistics is 2.17
There we reject the null hypothesis. And thus we conclude that the mean annual Medicare spending in Indianapolis is lower than the national mean.
Find the amount of tax and the tax rate. Round to nearest hundredth of a percent . Cost of item: $118 Selling price: $132.37 Tax Amount: $ Tax Rate percentage%
Answer:
The amount of tax is $14.37 and the tax rate percentage is 12.18%
Step-by-step explanation:
Find the amount of tax by finding the difference between the cost and selling price:
132.37 - 118
= 14.37
Find the tax rate percentage by dividing the tax by the original cost, and multiplying it by 100:
(14.37/118) x 100
= 12.18
The amount of tax is $14.37 and the tax rate percentage is 12.18%

1. Which expression represents the
factored form of x2 - 13x + 36?
A (x - 4)(x - 9)
B (x - 3)(x - 12)
C (x + 9)x - 4)
D (x + 12)(x - 3)
Answer: Hello, There! your Answer is Below
A (x - 4)(x - 9)
Step-by-step explanation:
Find p, and q, knowing sum = b = 13 and product c = 36. Compose factor pairs of 36-> (2, 18)(2, 12)(4, 9). this last sum is 9 = b. Then p = 4 and q = 9

Find the greatest power of 3 that is divisible of 100!
Answer:
There is no greatest power of 3 that is divisible of 100.
Step-by-step explanation:
Since any number can always be divisible of 100, there would be no greatest power of 3 that is divisible of 100 since the powers can go on and on forever without stopping, and all powers of 3 is able to be divided by 100.
Find the value of c that makes each trinomial a perfect square. Then write the trinomial as a perfect square.
6. x2 – 20x + c
a. c = 64; (x – 8)2 b. c = 20; (x – 10)2 c. c = 100; (x + 10)2 d. c = 100; (x – 10)2
Answer:
d. c = 100; (x – 10)²
Step-by-step explanation:
Note that (x+a)²=x²+2ax+a².
In our case, 2a=-20, so 'a' must be -10.
Since c=a², and a=-10, c=(-10²)=100.
Since a=-10, the perfect square is (x – 10)²

The long side of a rectangle is 2b + 3 units, and its area is 2b ^ 2 - 5b - 12 Find the width .
Answer:
b - 4
Step-by-step explanation:
This can be done by factoring.
Area = length x width
2b^2 - 5b - 12 = (2b + 3)( ???)
Factor the area into (2b + 3)(b - 4). The width is b - 4.
Answer:
The answer is b - 4
Step-by-step explanation:
Find the slope (m) and y-intercept (b) of each line.
Answer:
y-int:(0,-2)
slope: 5/2
Step-by-step explanation:
slope is rise over run, so you just need to find 2 points (0,-2) and (2,3) and calculate (3-(-2))/(2-0) and get 5/2. y intercept is just the point located at X=0
Answer:
The y-intercept is (0, -2) and the slope is 5/2

Answer:
New volume will become 187.5 inch²
Step-by-step explanation:
Initial volume,
V = lbh
Put all the values,
V = 6.25 × 2.5 × 6
V = 93.75 inch³
When the length is doubled, l' = 2(6) = 12 inch
New volume,
V' = 12 × 6.25 × 2.5
= 187.5 inch²
So, when the length is doubled, the new volume will become 187.5 inch².

Step-by-step explanation:
B.
AC =BC
2x-6=x+8
2x-x=8+6
x=14
5) AC = 2x-6=2(14)-6=28-6= 22
6) BC = x+8= 14+8= 22
7) AB = AC+BC = 22+22= 44
C.
AC =BC
4x+10=7x-5
4x-7x= -5-10
-3x= -15
x= -15/-3 = 5
8) AC = 4x+10=4(5) +10=20+10= 30
9) BC = 7x-5= 7(5) -5=35-5= 30
10) AB = AC+BC = 30+30= 60
B) Solution
AC = BC
→ 2x-6 = x+8
→ 2x-x = 8+6
→ x = 14
5:- AC = 2x-6 = 2(14)-6 = 28-6 = 22
6:- BC = x+8 = 14+8 = 22
7:- AB = AC+BC = 22+22 = 44
C) Solution
AC = BC
→ 4x+10 = 7x-5
→ 4x-7x = -5-10
→ -3x = -15
→ x = -15/-3
→ x = 5
8:- AC = 4x+10 = 4(5) +10 = 20+10 = 30
9:- BC = 7x-5 = 7(5)-5 = 35-5 = 30
10:- AB = AC+BC = 30+30 = 60

Barak asked 50 students which type of flower they liked best. The results are displayed in the pie chart. If Barak asked 200 students which flower they liked best, how many students would you predict would choose tulips?
A. 15
B. 30
C. 60
D. 67
Answer:
C. 60 among 200 students would like Tulip (Assuming pie chart - 15 among 50 students like Tulip)
Step-by-step explanation:
Percent students liking tulip = (Tulip liking students / Total students) x 100
= (15 / 50) x 100 = 30%
Expected students to like Tulip among 200 students = 30% of 200
( 30 / 100 ) x 200
= 60 students
