Answer:

  33 1/3%

Step-by-step explanation:

The percentage change is ...

  difference/base × 100% = (120000 -90000)/90000 × 100%

  = 1/3 × 100% = 33 1/3%

100 points who ever get this right!!

Answers

Answer:

3. A = (0,-3)

    B = (4,-2)

   C = (-1,1)

4. A = (0,-6)

    B = (4,-5)

   C = (-1,-2)

Step-by-step explanation:

3) Reverse coordinates (-3,0), (-2,4), (1,-1) to A=(0,-3), B=(4,-2), C=(-1,1).

4) These coordinates (0,-3), (4,-2), (-1,1) need to be moved 3 units down.

So number four answer is A=(0,-6), B=(4,-5), C=(-1,-2).

I hope this helped you.

Answer:

3)A = (0,-3)

B = (4,-2)

C = (-1,1)

4)A = (0,-6)

B = (4,-5)

C = (-1,-2)

the difference of two numbers is 7. Three times the greater number is 72. find the numbers​

Answers

Answer:

[tex]\huge\boxed{\tt{x = 24, y = 17}}[/tex]

Step-by-step explanation:

Let the greater number be x and the smaller number be y.

So,

Condition # 1:

x - y = 7 --------------(1)

Condition # 2:

3x = 72 --------------(2)

Taking Eq. (2)

3x = 72

Divide both sides by 3

x = 72 / 3

x = 24

Now, Put x = 24 in Eq. (1)

24 - y = 7

Subtract 24 to both sides

-y = 7 - 24

-y = -17

y = 17

What is the sum of the two polynomials?

Answers

Given:

The two models for the two polynomials.

To find:

The sum of the given polynomials.

Solution:

From the given figure, it clear that

[tex]\text{First polynomial}=a^2+a+2[/tex]

[tex]\text{Second polynomial}=-a-1[/tex]

Adding both polynomials, we get

[tex]Sum=a^2+a+2+(-a-1)[/tex]

[tex]Sum=a^2+a+2-a-1[/tex]

[tex]Sum=a^2+1[/tex]

Therefore, the correct option is A.

Sheila in her study partner flipped a coin 120 times they flipped 70 has and 50 tails what is the experimental probability that the next flip will be heads up?

Answers

Answer:

7/12 = 0.5833 = 58.33% experimental probability that the next flip will be heads up.

Step-by-step explanation:

Experimental probability:

An experimental probability is given by the number of desired outcomes divided by the number of total outcomes, considering a number of previous trials.

What is the experimental probability that the next flip will be heads up?

120 previous trials.

70 were heads.

So

[tex]p = \frac{70}{120} = \frac{7}{12} = 0.5833[/tex]

7/12 = 0.5833 = 58.33% experimental probability that the next flip will be heads up.

Beryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal.) The results were as follows:

Duration of Exposure
< 1 1 to < 5 >= 5
Diseased 12 10 18
Sensitized 14 18 13
Normal 66 142 210

Required:
a. Compute the expected frequencies of diseased workers.
b. Compute the expected frequencies of sensitized workers.
c. How many degrees of freedom are there?

Answers

Answer:

1. Has been answered below

2. Degree of freedom is 4

Step-by-step explanation:

Row 1: 12+10+18 = 40

Row 2: 14+18+13 = 45

Row 3: 66+142+210 = 418

Grand total = 40+45+418 = 503

Column 1 : 12+14+66 = 92

Column 2: 10+18+142 = 170

Column 3: 18+13+210 = 241

Total = 92+170+241 = 503

Expected frequencies of diseased workers

92x40/503 = 7.316

170x40/503 = 13.52

241 x 40/503 = 19.165

Expected frequencies of sensitized workers

92x45/503 = 8.23

170x45/503 = 15.20

241x 45/503 = 21.56

Degree of freedom

Amy is attending physical therapy after knee surgery. She walked 6 1/4 miles over 3 days. How many miles is this per
day? (Simplify the answer and write it as a mixed number)

Answers

Answer:

Step-by-step explanation:

2 1/12 miles per day

The number of miles Amy walked per day is given by the equation

A = 2 1/12 miles

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The total number of miles walked by Amy = 6 1/4 miles

The total number of miles walked by Amy = 25/4 miles

And , the number of days = 3 days

So , the number of miles per day A = total number of miles walked by Amy / number of days

Substituting the values in the equation , we get

The number of miles per day A = ( 25/4 ) / 3

The number of miles per day A = 25/12

The number of miles per day A = 2 1/12 miles

Hence , the equation is A = 2 1/12 miles
