Answer:

y = 2x - 3

Step-by-step explanation:

The negative recipricol is -1/(-1/2) = 2

Use point-slope equation:

y-y1 = m(x-x1)

x1 = 3, y1=3

y-3 = 2(x-3)

Which of the following represents the hypotheses that we will be testing, assuming that p1 represents the population proportion of all young adults 20-39 who report using their horns and that p2 represents the population proportion of all older adults 60+ who report using their horns?
a. H0: p1=p2 versus Ha: p1>p2
b. H0: p1=p2 versus Ha: p1 c. H0: p1=p2 versus Ha: p2>p1
d. H0: p1=p2 versus Ha: p1=/=p2

Answers

Answer:

a. H0: p1=p2 versus Ha: p1>p2

Step-by-step explanation:

Given that

p1 represent the proportion of the population for young allots 20-39

And, p2 denotes the proportion of the population for all older adults that are above 60

So,

We need to find out the hypotheses

What is order of operations?

Order of operations is a set of rules to perform operations in an arithmetic expression.

PEMDAS is an acronym used to mention the order of operations to be followed while solving expressions having multiple operations. PEMDAS stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

Given expression

(3 + 1) + 27 ÷ 9

Using order of operations,

Solving Parentheses

= 4 + 27 ÷ 9

Solving Division operation

= 4 + 3

Solving Addition operation

= 7

Answer:

Interger: 0.35, -2, 1/4

Not an Interger: 26.00, 21/3

Step-by-step explanation:

Decimals, negatives, and fraction all fall into the category of integers along with others

0.35, -2, 1/4 fall into the category of either fractions, negatives, or decimals which makes them, in turn, fall into the category of integers

26.00 looks like a decimal but since the 0's don't need to be there, it's  actually 26, which is not a integer

21/3 is an improper fraction which, when simplified, is 7, which is not an integer

what does x=?

Answers

Answer:

#1: x=8, #2: x=21, #3: x=9

Step-by-step explanation:

So, to solve each of these x's, we need to do two things:

Find the scale factor

Then scale for x.

So lets start off with the first one.

We have a side value fo 3.

In the scaled version, we have the same side with a value of 6.

To find the scale, divide the 6 by 3:

6/3

=

2

So our scale is 2.

Next, lets look at our value on the traingle we know, and solve for the unkown x. We know that on the orginal traingle, its 4. For the version thats 2 times bigger, its x

So to solve this, multiply the 4 by 2:

4*2

=

8

This is your x value for the first question.

Next we have the side value 12 for the trapezoid. For the one next to it, the trapezoid has the same side with a value of 18.

To find the scale, lets divide 18 by 12.

18/12

=

1.5

That is our scale factor.

In these trapezoids, the bottom value is orginally 14.

In the scaled version, which we know is 1.5 times bigger, we have x.

To solve for x, lets multiply the 14 by 1,5:

14*1.5

=

21

So we know our x is 21 for the second answer.

Finally we have the third question.

This one is opposite to the last ones, where the smaller value has the missing x value.

Here our top side value is 20.

On the scaled version it is 15.

Lets divide 15 by 20, instead of what we normally do. Which would have been 20 by 15:

15/20

=

.75

Now, with this scale factor, our x will be smaller than the known value. Looking at the side length, the orginal value is 12.

On the scaled side length that is 0.75 times as big, its x

So lets multiply 12 by 0.75:

12*0.75

=

9

So this is your last x value, for your third answer!

This might seem long and tedious, but its actually a simple way of thinking about it, and you may find that you can quickly do this in your head, instead of a shorter, more complex way.

Hope this helps!

The average salary for all 27 Arizona Diamondbacks in the 2005 baseball season was $2,308,488, with a standard deviation of $3,427,508. The population, all National League baseball players in 2005, earned an average salary of $2,585,804, with a standard deviation of $3,500,708. Does the average salary of the Diamondbacks players differ from that of all players in the National League

Answers

Answer:

The average salary  of the Diamondbacks players  does not differ from that of all players in the National League.

Step-by-step explanation:

1) Formulate null and alternate hypothesis

H0: u1= u2 Ha: u1 ≠ u2

The null hypothesis is that the average salary of the Diamondbacks players does not differ from that of all players in the National League

against the claim

that the average salary of the Diamondbacks players differ from that of all players in the National League

The data given is

x1`= $2,308,488,  s1=  $3,427,508   and  n1 = 27

x2`=  $2,585,804,      s2=$3,500,708   and n2 = 27

2) The test statistic is

z= x1-x2/ sqrt( σ1 ²/n1 + σ2²/n2)

Putting the values

z = $2,308,488- $2,585,804/ sqrt( 3,427,508²/27 + 3,500,708²/27)

z= -0.294

3) The significance level is 0.05

The critical region is Z  =±1.96

4) Since the calculated value of z=  -0.294 is less than the z ∝=±1.96 we  do not reject H0.

5) the P-value can be calculated using the calculator.

The p-value is p = 0.7687

The average salary  of the Diamondbacks players  does not differ from that of all players in the National League.

9) The present ages of Juna and Jubin are in the ratio 5:8. After 4 years the sum
of their ages will be 34. Find their present ages.​

Answers

Answer:

Present age of Juna = 10 years

Present age of Jubin = 16 years

Step-by-step explanation:

Ratio of present ages = 5: 8

Let the present ages of:

Juna be 5x years and Jubin be 8x years

(where x is the common multiplier of the given ratios)

Four years after:

Juna's age = (5x + 4) years

Jubin's age = (8x + 4) years

According to the question:

(5x + 4) + (8x + 4) = 34

13x + 8 = 34

13x = 34 - 8

13x = 26

x = 26/13

x = 2

5x = 5*2 = 10 years

8x = 8*2 = 16 years

Hence,

Present age of Juna = 10 years

Present age of Jubin = 16 years
