HURRRRYYYYYYY PLEASE Write the equation of the line that passes through the points (-8,-1) and (5,−7). Put your answer in full

Zinaida [17]

Answer:

y + 8 = 2x + 2

Step-by-step explanation:

Use the points given to find the slope. Divide the difference in y-values by the difference in x-values.

(-1) - (-7) = 6

5 - (-8) = 3

6/3 = 2

The slope is 2.

Now, pick one of the points to put in point-slope form. It doesn't matter which. You will get the right answer either way. I will use (-1, -8).

y - y₁ = m(x - x₁)

y - (-8) = 2(x - (-1))

y + 8 = 2(x + 1)

y + 8 = 2x + 2

Suppose that an experiment consists of flipping a coin 3 times and observing the resulting sequence of heads and tails. Find the

ki77a [65]

Using the binomial distribution, it is found that there is a 0.125 = 12.5% probability of observing exactly 3 tails.

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

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem, considering 3 tosses of a fair coin, the parameters are n = 3 and p = 0.5.

The probability of 3 tails is P(X = 3), hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 3) = C_{3,3}.(0.5)^{3}.(0.5)^{0} = 0.125$

0.125 = 12.5% probability of observing exactly 3 tails.

Please help!! Please give step by step so i can understand

miss Akunina [59]

Answer:

p = - 14

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ ÷ $a^{n}$ = $a^{(m-n)}$

$(a^{m}) ^{n}$ = $a^{mn}$

Note 81 = 9² and 729 = 9³

Given

$(81)^{-4}$ ÷ $(729)^{2-p}$

= $(9^{2}) ^{-4}$ ÷ $(9^{3}) ^{2-p}$

= $9^{-8}$ ÷ $9^{6-3p}$

= $9^{-8-(6-3p)}$

= $9^{-8-6+3p}$

= $9^{3p-14}$

Thus

$9^{3p-14}$ = $9^{4p}$

Since bases on both sides are equal then equate the exponents

4p = 3p - 14 ( subtract 3p from both sides )

p = - 14

there are 239 people in the first six rows of the movie theater if the same number of people are in the next six rows about how

bija089 [108]

Answer:

478 people

Step-by-step explanation:

All you need to do for this problem is simply multiply 239 by 2. If the first 6 rows are 239 people, and so are the next 6, that's all you need to do.

239*2=478
