Answer:

2014 salary = 125 of 2013 salary

Therefore if 2013 salary is 100, 2014 salary is 125

x% of 125 = 100

125x/100= 100

x = 100*100/125

x = 80

His previous salary is 80% of his present salary

Answer:

80%

Step-by-step explanation:

Focus on the important parts of the problem:

The present salary is 25% more than the previous salary.

previous = % of present ?

Use a mock/fake situation. Let' say the previous salary is $100.

100 = % of present

Present salary is $100 increased by 25%.

$100 X 1.25 = $125

100 = % of 125

Solve this in decimal form (convert it to a percentage later).

Let x be the percentage in decimal form.

100 = 125x

100/125 = x Isolate "x" by dividing by sides by 125

x = 0.80

Convert 0.80 to percentage by multiplying by 100.

0.80 X 100 = 80%

When comparing two things using percentage, 100% is the same. Less than 100% is less and more than 100% is more.

Since his previous salary was less than his present salary, this answer makes sense.

Therefore his previous salary was 80% of his present salary.

I’m confused about these questions. Compositions and inverses ⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️

Answer:

1. (f+g)(x) = 2x^2 +4x +2

2. (f -g)(x) = -2x^2 +4x -4

5. (f+g)(x) = x^2 +2x -1

6. (g -f)(x) = x^2 -2x -1

Step-by-step explanation:

None of these are compositions. They are only sums or differences.

(f±g)(x) = f(x) ± g(x)

1. (f+g)(x) = f(x) +g(x) = (4x -1) +(2x^2 +3)

(f+g)(x) = 2x^2 +4x +2

2. (f -g)(x) = f(x) -g(x) = (4x -1) -(2x^2 +3)

(f -g)(x) = -2x^2 +4x -4

5. (f +g)(x) = f(x) +g(x) = (2x) +(x^2 -1)

(f+g)(x) = x^2 +2x -1

6. (g -f)(x) = g(x) -f(x) = (x^2 -1) -(2x)

(g -f)(x) = x^2 -2x -1

For an F distribution, the number of degrees of freedom for the numerator a. must be larger than the number of degrees of freedo

Alecsey [184]

Answer:

b. can be larger, smaller, or equal to the number of degrees of freedom for the denominator.

Step-by-step explanation:

The distribution of all possible values of the f statistic is called an F distribution with various degree of freedom. For an F distribution, the F statistic is greater than or equal to zero and as the degrees of freedom for the numerator and for the denominator get larger, the curve approximates the normal.

For an F distribution, the number of degrees of freedom for the numerator can be larger, smaller, or equal to the number of degrees of freedom for the denominator.

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.

mafiozo [28]

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:

$\frac{x}{32} =\frac{21}{24}$

Cross multiply.

$24x = 672$

Simplify.

$x=28$

Subtract the value of DB to find AD.

$28-21=7$

$AD=7$

Please help me. i want to have this finished.

Anuta_ua [19.1K]

We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.

10x- 9(x-2)=24

Distribute.

10x- 9x+18= 24

x+18= 24

Subtract 18 on both sides.

x= 6

Now, plug in x.

y= (6)-2

y= 4

We can check this to see if this works:

4= 6-2, 4=4

10(6)- 9(4)= 24

60-36= 24, 24=24

x=6 and y=4

I hope this helps!
