7.9 11.6

9 12.7

11.3 15.0

13 16.7

Step-by-step explanation:

If they gave you the width, you add 3.7 to get the length.

If they gave you the length, you subtract 3.7 to get the width.

How do i write y = x -4 in a x and y chart/table?

IrinaK [193]

Okay well it kept saying that I for some reason was not using appropriate words so my long response got deleted.

tldr; we can treat this like a box that we put something into (x) and we get something back from it (y).

We can then take this data we get and put it in a table. This is useful for finding patterns.

I will post a picture of what a table may look like.

Hope this Helps!

NEED HELP FAST!!!!! The graph below compares plant height to the age of the plant, in weeks. Y=1.3x-0.8 Based on the graph, whic

salantis [7]

Answer:

C) 6 inches

Step-by-step explanation:

Given function:

$Y=1.3x-0.8$

The function compares plant height in inches to the age of plant in weeks.

So, we can say

$Y$ represents height of plant in inches.

$x$ represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin $x=5$ in the given function and evaluate $Y$

⇒ $Y=1.3(5)-0.8$

⇒ $Y=6.5-0.8$

⇒ $Y=5.7$ inches

Thus the approximate height of plant in 5 weeks would be $\approx 6$ inches

What is the slope of the line through (6,0) and (7,1)

monitta

$\huge \bf༆ Answer ༄$

Let's find the slope of line passing through given points ~

$\sf \dfrac{y2 - y}{x2 - x1}$

$\sf \dfrac{1 - 0}{7 - 6}$

$\sf \dfrac{1}{1}$

$\sf1$

Hence, slope of the line will be 1.

A center for medical services reported that there were 295,000 appeals for hospitalization and other services. For this group, 4

pshichka [43]

Answer:

a) 0.0025 = 0.25% probability that none of the appeals will be successful.

b) 0.0207 = 2.07% probability that exactly one of the appeals will be successful.

c) 0.9768 = 97.68% probability that at least two of the appeals will be successful

Step-by-step explanation:

For each appeal, there are only two possible outcomes. Either it is succesful, or it is not. The probability of an appeal being succesful is independent of other appeals, so we use the binomial probability distribution 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.

45% of first-round appeals were successful.

This means that $p = 0.45$

Suppose 10 first-round appeals have just been received by a Medicare appeals office.

This means that $n = 10$

(a) Compute the probability that none of the appeals will be successful.

This is P(X = 0).

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

$P(X = 0) = C_{10,0}.(0.45)^{0}.(0.55)^{10} = 0.0025$

0.0025 = 0.25% probability that none of the appeals will be successful.

(b) Compute the probability that exactly one of the appeals will be successful.

This is P(X = 1).

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

$P(X = 1) = C_{10,1}.(0.45)^{1}.(0.55)^{9} = 0.0207$

0.0207 = 2.07% probability that exactly one of the appeals will be successful.

(c) What is the probability that at least two of the appeals will be successful

This is $P(X \geq 2)$

Either less than two appeals are succesful, or at least two are. The sum of the probabilities of these events is decimal 1. So

$P(X < 2) + P(X \geq 2) = 1$

$P(X < 2) = P(X = 0) + P(X = 1) = 0.0025 + 0.0207 = 0.0232$

$P(X \geq 2) = 1 - P(X < 2) = 1 - 0.0232 = 0.9768$

0.9768 = 97.68% probability that at least two of the appeals will be successful
