Answer:

A. Negative correlation

B. Data isn't given

Step-by-step explanation:

A. A positive correlation occurs when variables that are related(not zero correlation)increase together, in other words variable a(independent variable) increases and makes variable b(dependent variable) increase too. There will be a negative correlation if the opposite happens, that is when variables that are related go in opposite directions, one increases while the other decreases. We observe from what we are told that a negative correlation occurs here since death rate from fires has likely(assumed) decreased as smoke detectors have increased.

Step-by-step explanation:

hope it's helpful ❤❤

THANK YOU.

Answer:

1 false

2 true

3 true

4 false

5 true

Step-by-step explanation:

f(a) = (2a - 7 + a^2) and g(a) = (5 – a).

1 false f(a) is a second degree polynomial and g(a) is a first degree polynomial

When added together, they will be a second degree polynomial

2. true  When we add and subtract polynomials, we still get a polynomial, so it is closed under addition and subtraction

3.  true  f(a) + g(a) = (2a - 7 + a^2) + (5 – a)

Combining like terms = a^2 +a -2

4.  false   f(a) - g(a) = (2a - 7 + a^2) - (5 – a)

Distributing the minus sign (2a - 7 + a^2) - 5 + a

Combining like terms  a^2 +3a -12

5.  true  f(a)* g(a)  = (2a - 7 + a^2)  (5 – a).

Distribute

                      (2a - 7 + a^2)  (5)  – (2a - 7 + a^2)  (a)

                       10a -35a +5a^2 -2a^2 -7a +a^3

Combining like term

-a^3 + 3 a^2 + 17 a - 35

Answer:

43

Step-by-step explanation:

3x - 17 and x - 9 are on a line together, so they add up to 180.

3x + 17 + x - 9 = 180

Then, you can solve the equation:

4x + 8 = 180

4x = 172

x = 43 degrees

Step-by-step explanation:

The Least Common Multiple, LCM, also known as the Lowest Common Multiple or  Least Common Divisor, LCD, of two numbers is the smallest natural number that can be divided evenly by either of the two numbers

Reason:

The given parameters, starting from the runner on the outer track are;

Number of spaces covered by the runner on the outer track, n₁ = 5 spaces

Number of spaces covered by the next inner runner, n₂ = 1 space

Number of spaces covered by the next inner runner, n₃ = 3 spaces

Number of spaces covered by the next runner, n₄ = 2 spaces

The numbered spot at which all the runners will be next to one another = Required

Solution:

A spot where all the runners will be next to one another is given by the Lowest Common Multiple, LCM, of their speeds or number of spaces traveled in the same time as follows;

The LCM of 5, 1, 3, and 2 = 5 × 1 × 3 × 2 = 30

Therefore, when the first runner runs 30 spaces, we have;

[tex]Time = \dfrac{30}{5} = 6[/tex]

The time taken is 6 time units

The point the runner stops is at space 30- (30 -19) = Spot 19

The distance traveled by the runner 2 at the same time is 6 × 1 = 6

∴ The distance traveled by the runner 2 at the same time = 6 spaces

The distance traveled by the runner 3 at the same time is 6 × 3 = 18

∴ The distance runner 3 travels at the same time = 18 spaces

Runner 4 travels a distance at the same time of  6 × 2 = 12

∴ Distance runner 4 travels = 12 spaces

Therefore;

The numbered spot at which all the runners will be next to one another is spot 19

Answer:

k=40

Step-by-step explanation:

subtract 12 from k we would get 28

under 21 years of age= 40     25         20  tot= 85

between 21 and 40=     35     20         30  tot = 85

       over 40=               20     30         35   tot = 85

If one of the 255 subjects is randomly selected

P (over 40) = 85/255 = 1/3

Answer:  The experimental probability and relative frequency are the same.

Step-by-step explanation:  In the question it ask you to compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number. If you compare these two things the outcome would be the same because these two terms are the same thing.

Look at the examples provided below:

"Example: you conduct an experiment where you flip a coin 100 times. ... So the experimental probability of getting tails in 100 trials is 53%, and 47 for getting heads in 100 trials."

Experimental probability

During the party, Scoundrel offered her left paw 62.5% of the time.

62.5% • 100 = 0.625 • 100 = 62.5 times.

it wouldn't make sense to offer a paw 0.5 times, so round 62.5 to 63. After 100 trials, Jenna can expect that Scoundrel will offer the left paw 63 times.
