Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 proble
worth either 5 points or 2 points. Write a system of equations that can be used to find how ma
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2
x + y = 29, 5x + 2y = 100
O x + y = 100, 5x + 2y = 29
5x + y = 29, 2y + x = 100
2x + y = 100, 5y + x = 29

The sigma symbol means that you have to add them all up so the sum is 6. Therefore,

(6)^2 = 36

Answer:

36

Step-by-step explanation:

Sum the terms (x - 2) for x = 2 to 5 then square the result

[ (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) ]²

= ( 0 + 1 + 2 + 3 )²

= (6)²

= 36

Omar, Hala and Lujain got paid a total of $240 for cleaning neighborhood cars. They split the money in the ratio of 5: 9: 10. How much money did Omar earn?

Answers

Answer:

Total amount Omar earn = $120

Step-by-step explanation:

Given:

Total amount Omar, Hala and Lujain got paid = $240

Ratio of money Omar, Hala and Lujain got paid = 5:9:10

Find:

Total amount Omar earn

Computation:

Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]

Total amount Omar earn = [240][5 / (5+9+10)]

Total amount Omar earn = [240][5 / (24)]

Total amount Omar earn = [24][5]

Total amount Omar earn = $120

Answers

Answer:

Step-by-step explanation:

Problem 1

g(-23) = 3

g(0) = 5

2 = g(10)

1 = g(34)

Problem 2

No, because g(x) = f(-x).  For g(x) to inverse of f(x), g(f(x)) = x

Problem 3

tan(50) = 1.19

Height of statue = 250*1.19 - 150

= 147.9 ft

Problem 4

cosθ = 9/12

θ = 41.41 deg.

Answer:

Step-by-step explanation:

g(x) is inverse of f(x)

so g(f(x))=x

g(-23)=3

g(0)=5

g(10)=2

g((34)=1

no, it is an inverse

4 inverse fn, g(r(x))=x

but here g(x)=r(-x)

so g(r(x))=r(-r(x)) n NOT =x

pedestal + statue = 250*tan(50degree) = 297.94

statue ht = 297.94-150 = 147.94 ft

cos(theta) = 9/12

theta = 41.41 deg.

A student had 10 marks in mathematics. But he remembers only 7 of them:
1,1,2,2,3,4,5. The mode of the marks is 3 and the mean is 2.9. What are the
missing marks? Once you manage to find these marks, create a frequency
table for the students' scores and visualize the results with a bar chart.

Answers

Answer:

The missing marks are 3, 3, and 5.

Step-by-step explanation:

Since the mode is 3, that means it's the number that occurs most often. The numbers 1 and 2 occur twice so there must be at least 3 3's on the list. But since the mean is 2.9, the third mark cannot be a 3 because it will make the mean only 2.7 so the 3rd mark can be either a 4 or a 5. Using 5 will make the mean 2.9. I take it that you know how to make a bar graph for this problem.

Numerator:  [tex]\pm 1[/tex]
