Answer:

Identity Property of Zero

The identity property of 0 states that if you add or subtract 0 from any number, the number will always stay the same. Here are some examples involving whole numbers: 3+0=3 7−0=7 Therefore, x+0=0+x=x. This is also known as the additive identity property of 0.

Answer:

$a=7,\\b=3$

Step-by-step explanation:

The area of a rectangle is equal to $A=l\cdot w$ , where $l$ is the length of the rectangle and $w$ is the width of the rectangle. In a rectangle, opposite sides are equal.

Therefore, we can write the following system of equations:

$\begin{cases}a\cdot (9+b)=84,\\a\cdot b=21\end{cases}$

Expand the first equation:

$9a+ab=84$

Substitute the second equation into the first ( $ab=21$ ):

$9a+21=84,\\9a=63,\\a=\boxed{7}$

Solving for $b$ :

$7b=21,\\b=\frac{21}{7}=\boxed{3}$

What is the slope of the line that contains these points? x| -7. -6. -5. -4 ----------------------------------------------------

zepelin [54]

Answer:

Step-by-step explanation:

Given the line containing the points.

x | -7. -6. -5. -4

y | 21. 17. 13. 9

The slope of the line is expressed as m = Δy/Δx = y₂-y₁/x₂-x₁

Using the coordinates y (21, 17) and corresponding value of x(-7, -6)

y₁ = 21, y₂ = 17 x₁ = -7, x₂ = -6

Substituting the values into the formula for calculating the slope, we have;

m = Δy/Δx = 17-21/-6-(-7)

m = -4/-6+7

m = -4/1

m = -4

<em>Hence the slope of the line that contains these points is -4</em>

In New York State, 38% of the houses have a pool and 21% of the houses have both a pool and a hot tub. What is the probability t

SSSSS [86.1K]

Answer:

Probability that a house has a hot tub given that it has a pool is 55%.

Step-by-step explanation:

We are given that in New York State, 38% of the houses have a pool and 21% of the houses have both a pool and a hot tub.

Let the probability that houses have a pool = P(A) = 0.38

Also, let B = event that houses have a hot tub

Probability that houses have both a pool and a hot tub = $P(A \bigcap B)$ = 0.21

Now, the conditional probability that a house has a hot tub given that it has a pool is given by = P(B / A)

<u>As we know that</u>; P(B / A) = $\frac{P(A \bigcap B)}{P(A) }$

= $\frac{0.21}{0.38}$

= 0.553 ≈ 55%

Hence, the probability that a house has a hot tub given that it has a pool is 55%.
