Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points) Yes, it is a valid inference because his classmates make up a random sample of the students in the school Yes, it is a valid inference because he asked all 26 students in his science class No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

B. $76,500
C. $25,684
O D. $28,800

Answers

Answer:

A. $22,032

Step-by-step explanation:

FICA includes both social security tax (6.2%) and Medicare tax (1.45%), for a total tax rate of 7.65%.

0.0765 × $288,000 = $22,032 . . . FICA tax

An inequality for m is no greater than 35

Answers

Answer:

m ≤ 35

Step-by-step explanation:

The variable "m" is no greater than 35.

Note that "no greater" means that it can be up to the certain number (in this case, 35), but cannot exceed it. Your answer will be:

m is less than or equal to 35, or m ≤ 35.

Solve each system of linear equations by substitution you will get an x, y point for solutionshow steps
y = x - 4 2x + y = 5

next set is
x + 4y = 6 y = -x + 3

next set is
x + 2y = 6 x - y = 3

next set is
3x - 2y = 9 y = 2x - 7

Answers

{y = x - 4

=> 2x+x-4=5 => 3x=9......x=3

{2x + y = 5 y=3-4=-1

{x+4y=6

{y=-x+3

=> x+4(-x+3)=6

x-4x+12=6

x=2

y=-2+3=1

y=1

PLEASE NEED THIS DONE AS FAST AS POSSIBLE!!!!!!!!!!!!!!!!!
IT MUST BE CORRECT

Answers

Answer:

1)7.288 feet

2)11.6 feet

3)safe

4) 3.7 feet

5) ∅ $= tan^(-1)(1.5) = 56.31 degrees$

6)∅1 $= tan^(-1)(2) = 63.43 degrees$

∅2 $= tan^(-1)(1.2) = 50.19 degrees$

Step-by-step explanation:

1) The door barn is rectangular in shape. The length is 9 feet and The angle between diagonal and side is 39 degrees.

Applying trigonometry,

tan(39) = $(opposite)/(adjacent) = (s)/(9)$ = 0.809

Thus, s= $(9)(0.809) = 7.288 feet$

2) Applying pythagoras theorm,

$(Diagonal)^(2) = (9)^(2) + (7.288)^(2) =134.115$

Diagonal length (d) = 11.58 feet. Nearest tenth place = 11.6 feet

3) The length of ladder is 14 foot and height from ground is 13.5 feet.

Applying trigonometry,

sin(∅) = $(opposite)/(hypotenous) = (13.5)/(14)$ = 0.964

∅ = angle of elevation = $sin^(-1)(0.964)$ = 74.57 ≈ 75 degrees.

Thus tractor can climb safely.

4)Applying, pythgoras theorm,

$14^(2) = (13.5)^(2) + x^(2)$

x = $\sqrt{14^(2)-(13.5)^(2)} = 3.708$

Thus, ladder should be placed at distance 3.7 feet

5)Let angle of elevation be ∅.

tan(∅) = $(30)/(20) = 1.5$

∅ $= tan^(-1)(1.5) = 56.31 degrees$

6)After moving 5 feet closer to barn, Let angle of elevation for light near barn be ∅1 and for farther one be ∅2.

Thus,

tan(∅1) = $(30)/(15) = 2$

∅1 $= tan^(-1)(2) = 63.43 degrees$

tan(∅2) = $(30)/(25) = 1.2$

∅2 $= tan^(-1)(1.2) = 50.19 degrees$
