Answers

Answer:

= 0.714 (in decimal fraction)

The probability that the death in 2014 was not caused by heart diseases or Unintentional Injuries = 0.714

= 0.714

Step-by-step explanation:

Let's interpret the question our way ti solve it .

Total deaths in 2014:

2626418

Death caused by Heart Diseases:

614348

Death caused by Unintentional Injuries:

750401

Therefore, we can deduced that, the number of death not caused by Heart Diseases or Unintentional Injuries = Total deaths in 2014 minus sum of the recorded death.

= 2626418 - ( 614348 + 136053)

= 2626418 - 750401

= 1876017.

Now, the probability that there were death in 2014 is 1 (one)

To find the probability that death we're not caused by heart diseases or Unintentional Injuries:

= 1 - Pr (Death Caused by heart diseases) + Pr (Death causes by Unintentional Injuries)

= 1 - (0.234 + 0.052)

= 1 - 0.286

= 0.714

To Check:

= 1876017 / 2626418

Divide to the lowest term

=0.714

The probability that a death in 2014 was not caused by diseases of the heart or unintentional injuries is approximately 0.714 or 71.4%.

Here, we have to find the probability that a death in 2014 was not caused by diseases of the heart or unintentional injuries, we need to subtract the number of deaths caused by these two specific causes from the total number of deaths and then divide it by the total number of deaths.

Total number of deaths in 2014: 2,626,418

Number of deaths caused by diseases of the heart: 614,348

Number of deaths caused by unintentional injuries: 136,053

Number of deaths not caused by diseases of the heart or unintentional injuries = Total deaths - Deaths caused by diseases of the heart - Deaths caused by unintentional injuries

Number of deaths not caused by diseases of the heart or unintentional injuries = 2,626,418 - 614,348 - 136,053

Number of deaths not caused by diseases of the heart or unintentional injuries = 1,876,017

Now, we can calculate the probability:

Probability = Number of deaths not caused by diseases of the heart or unintentional injuries / Total number of deaths

Probability = 1,876,017 / 2,626,418

Probability ≈ 0.714 (rounded to three decimal places)

So, the probability that a death in 2014 was not caused by diseases of the heart or unintentional injuries is approximately 0.714 or 71.4%.

Find the values of x and y.

X=?
Y=?

Answers

Answer:

x=85

y=65

Step-by-step explanation:

Right angle equals 90

then 180-90-20=70

Opposite angle =70

so 70+25+x=180

x=180-70-25=85

when u know x ,then 180-85=95

y=360-90-110-95=65

Scott is a software salesman. Let represent his total pay (in dollars). Let represent the number of copies of History is Fun he sells. Suppose that and are related by the equation 80x+2100=y Answer the questions below.

Note that a change can be an increase or a decrease.

For an increase, use a positive number. For a decrease, use a negative number.


What is the change in Scott's total pay for each copy of History is Fun he sells?



What is Scott's total pay if he doesn't sell any copies of History is Fun?

Answers

Answer:

A. $80

B. $2100

Step-by-step explanation:

Given:

80x+2100=y

Rewrite the equation

y = 80x + 2100

Where,

y = Scott's total pay (in dollars)

x = number of copies of History is Fun he sells

2100 = fixed pay

A.

Since, x = number of copies of History is Fun he sells

If x = 0

y = 80x + 2100

= 80(0) + 2100

= 0 + 2100

= 2100

y = $2100

If x = 1

y = 80x + 2100

= 80(1) + 2100

= 80 + 2100

= 2180

y = $2180

change in Scott's total pay for each copy of History is Fun he sells = $2180 - $2100

= $80

B. What is Scott's total pay if he doesn't sell any copies of History is Fun?

That is, when x = 0

y = 80x + 2100

= 80(0) + 2100

= 0 + 2100

= 2100

y = $2100

Determine the equivalent system for the given system of equations.4x − 5y = 2
3x − y = 8

4x − 5y = 2
13x − 8y = 4
4x − 5y = 2
10x + 3y = 15
4x − 5y = 2
13x − 8y = 26
4x − 5y = 2
7x + 6y = 10

Answers

Answer:

4x − 5y = 2

13x − 8y = 26

Step-by-step explanation:

The equivalent system must have the same solution as the given system of equations:

4x − 5y = 2

3x − y = 8

Here we have that:

y = 3x - 8

4x - 5y = 2

4x - 5(3x - 8) = 2

4x - 15x + 40 = 2

-11x = -38

x = (38)/(11)

y = 3x - 8 = (3*38)/(11) - (88)/(11) = (26)/(11)

Now, we have to verify which of these systems have this answer:

4x − 5y = 2

13x − 8y = 4

13x - 8y = 4

13(38)/(11) - 8(26)/(11) = (286)/(11) \neq 4

4x − 5y = 2

10x + 3y = 15

10x + 3y = 15

10(38)/(11) + 3(26)/(11) = (458)/(11) \neq 15

4x − 5y = 2

13x − 8y = 26

4x - 5y = 2

4(38)/(11) - 5(26)/(11) = (22)/(11) = 2

13x - 8y = 26

13(38)/(11) - 8(26)/(11) = (286)/(11) = 26

This is the correct answer

So this is the correct answer

4x − 5y = 2

7x + 6y = 10

Answer:

The answer is

(4x - 5y = 2) and (13x - 8y =26)
