Answer:

f(-8) = -18

Step-by-step explanation:

given :

f(x) = 2(x – 3) + 4

to find f(-8), simply substitute x= -8 into the function:

f(x) = 2(x – 3) + 4

f(-8) = 2[(-8) – 3] + 4

= 2[-8 – 3] + 4

= 2[-11] + 4

= -22+4

= -18

Find the distance between points P(4, 4) and Q(9, 3) to the nearest tenth
ddd [48]

Answer:

5.1 units

Step-by-step explanation:

(4, 4) & (9, 3)

To find the distance of two points, we use the distance formula:

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

Let's plug in what we know.

d = \sqrt{(9 - 4)^2 + (3 -4)^2 }

Evaluate the parentheses.

d = \sqrt{(5)^2 + (-1)^2 }

Evaluate the exponents.

d = \sqrt{(25) + (1)}

Add.

d = \sqrt{(26)}

Evaluate the square root.

d = \sqrt{26} or 5.0990 units

Round to the nearest 10th.

5.1 units

Hope this helps!

katen-ka-za [31]

Answer:

(-5 3/4, 1 2/3)

Step-by-step explanation:

the line intersects right before the -6, so it’s not -6. yet, it is as close to -6 as you can get which would be -5 3/4. meaning the closes would be the third choice.

The basketball team spends 20 minutes running laps and at least 15 minutes discussing plays. Practice lasts one hour and 45 minu
Allushta [10]

Answer:

x ≤ 75

Step-by-step explanation:

The computation of the inequality function is as follows:

Let us assume the remaining time left for other drills be x

Given that the team spends 20 minutes for running laps

And minimum of 15 minutes for discussing plays

Also practicing for last one hour and 45 minutes

Now as we know that

1 hour = 60 minutes

So total minutes would be

= 60 + 45

= 105 minutes

Total minutes spend by the team is

= 20 + 15

= 35 minutes

So now the remaining time left is

x ≤ 105 - 35

x ≤ 75

The expected values of the binomial distribution are given as follows:

1. 214.

2. 21.

3. 31.

<h3>What is the binomial probability distribution?</h3>

It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

For item 1, the parameters are:

p = 3/7, n = 500.

Hence the expected value is:

E(X) = np = 500 x 3/7 = 1500/7 = 214.

For item 2, the parameters are:

p = 0.083, n = 250.

Hence the expected value is:

E(X) = np = 250 x 0.083 = 21.

For item 3, the parameters are:

p = 1/13, n = 400.

Hence the expected value is:

E(X) = np = 400 x 1/13 = 31.
