In the coordinate plane, the length of the line segment that connects points at (0, -1) and (-7, -2) is 7.07 units.

<u>Step-by-step explanation:</u>

Here we have ,in coordinate plane we are given two points (0,-1 ) & ( -7,-2 ).

From Straight line concept, we know that Distance between any two pints in a plane i.e distance between points ( x1, y1) and (x2,y2) is given by:

D = \sqrt{(x_1 - x_2)^{2} + ( y_1-y_2)^{2}} , Here ( x_1, y_1)  = ( 0 , -1) and (x_2,y_2) = (-7,-2)

Putting values in above formula we get:

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

⇒D = \sqrt{(0 - (-7))^{2} + ( -1-(-2))^{2}}

⇒D = \sqrt{7^{2} + 1^{2}}

D = \sqrt{50}  units = 7.07 units

∴In the coordinate plane, the length of the line segment that connects points at 0, -1 and. -7, -2 is 7.07 units.

Construct the discrete probability distribution for the random variable described. Express the probabilities as simplified fract
lisov135 [29]

Answer:

P(X = 0) = 0.03125

P(X = 1) = 0.15625

P(X = 2) = 0.3125

P(X = 3) = 0.3125

P(X = 4) = 0.15625

P(X = 5) = 0.03125

Step-by-step explanation:

For each toss, there are only two possible outcomes. Either it is tails, or it is not. The probability of a toss resulting in tails is independent of any other toss, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

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

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

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

And p is the probability of X happening.

Fair coin:

Equally as likely to be heads or tails, so p = 0.5

5 tosses:

This means that n = 5

Probability distribution:

Probability of each outcome, so:

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

P(X = 0) = C_{5,0}.(0.5)^{0}.(0.5)^{5} = 0.03125

P(X = 1) = C_{5,1}.(0.5)^{1}.(0.5)^{4} = 0.15625

P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125

P(X = 3) = C_{5,3}.(0.5)^{3}.(0.5)^{2} = 0.3125

P(X = 4) = C_{5,4}.(0.5)^{4}.(0.5)^{1} = 0.15625

P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125

8. Misty created the number pattern below. 32, 28, 24, 20, ... If n represents a number in this pattern, which rule could be use
geniusboy [140]

Answer:

An = 32 - (4*(n-1))

Step-by-step explanation:

the starting term for this pattern is 32 (which you will need to include in the "rule")

you also know that the next term is the previous term - 4

so!

we can write this pattern as

An = 32 - (4*(n-1))

An = any number of term in the pattern

- ex). A2 = 28, A3 = 24, etc

n = the nth term

- the 3rd term = 24, the fourth term = 20, etc
