Answer:

1. f

2. a

3. b

4. e

5. c

6. d

1. I figured out how to order them by using the distance formula to calculate how far each point was, from the other.

2. (1, -10) and (1, -11)

3. (1, -10) and (1, 11)

Step-by-step explanation:

<u>Using Letter A, as example:</u>

To calculate the distance between the points, you use the formula:

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d = \sqrt{(2-2)^2+(10-4)^2}

d = \sqrt{0 + 36}

d = 6

Just do the same thing (plug in the numbers into the formula), and you should be able to get the correct answers.

Let f={(-2,4),(-1,2)(0,0)(1,-2),(2,5)}. let g ={(-33),(-1,1),(0,-3)(1,-4)(3,-6)}. What is g(f(2))?
taurus [48]

Answer:

g(f(2)) does not exist if

g={(-3,3),(-1,1),(0,-3),(1,-4),(3,-6)} and f={(-2,4),(-1,2),(0,0),(1,-2),(2,5)}.

Step-by-step explanation:

Hi. Welcome to Brainly.

When finding g(f(2)), you must compute f(2) first.

Looking at f={(-2,4),(-1,2),(0,0),(1,-2),(2,5)}, we see that the ordered pair (2,5) is contained within the set defined as the set f. This means f(2)=5.

So now we have g(f(2))=g(5).

We now need to look at our set named g, g={(-3,3),(-1,1),(0,-3),(1,-4),(3,-6)}. We see the the no ordered pair looks like (5,something). The only conclusion is that g(f(2)) does not exist.

X is a normally distributed random variable with a mean of 22 and a standard deviation of 5. The probability that x is less than
Alenkinab [10]

Answer:

0.0069

Step-by-step explanation:

According to the Question,

  • Given That, X is a normally distributed random variable with a mean of 22 and a standard deviation of 5. The probability that x is less than 9.7

We have, μ=22 , σ= 5 , P(X<9.7)=Area to the left of 9.7.

Z = (x-μ)/σ

Z = (9.7-22) / 5 ⇒ -2.46

Thus,

  • P(X<9.7)=P(Z < -2.46) ⇒ 0.0069 (From z-table)
