Point H is on line segment GI. Given GH = x + 6, HI = x + 5, and

Vaselesa [24]

Answer:

<h2>9</h2>

Step-by-step explanation:

If Point H is on line segment GI, then GH+HI = GI

Given the following parameters

GH = x + 6,

HI = x + 5, and

GI = 3x + 8

To determine the length of GH, we need to get the value of x first. To get x we will substitute the given parameters into the formula as shown;

x+6+(x+5) = 3x+8

2x+11 = 3x+8

collect like terms;

2x-3x = 8-11

-x = -3

divide both sides by -1;

-x/-1 = -3/-1

x = 3

Since GH = x+6

GH = 3+6

GH = 9

<em>Hence the numerical length of GH is 9</em>

NEED HELP!!!!!!!!!!! NO LINKS!!!!!!!

Answer:

3x=18

Step-by-step explanation:

We want to get the variable x by itself.

Since we see a -3 with the 3x, we want to move the 3 to the other side of the equal sign by adding 3 to both sides of the equal sign.

3x - 3 = 15

3x - 3 + 3 = 15 + 3

Then we get:

3x + 0 = 18

3x = 18

A consensus forecastis the average of a large number of individual analysts’ forecasts. Suppose the individual forecasts fora pa

Crank

Answer:

a) $P(X\geq 3.5)=P(\frac{X-\mu}{\sigma}\geq \frac{3.5-\mu}{\sigma})=P(Z\geq \frac{3.5-5.0}{1.2})=P(Z\geq -1.25)$

And we can find this probability using the z table or excel

$P(Z \geq$

b) $P(X\leq 6.0)=P(\frac{X-\mu}{\sigma}\leq \frac{6.0-\mu}{\sigma})=P(Z\leq \frac{6.0-5.0}{1.2})=P(Z\leq 0.833)$

And we can find this probability using the z table or excel:

$P(Z \leq$

c) $P(3.5$

And we can find this probability on this way:

$P(-1.25$

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.

$P(-1.25$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Part a

Let X the random variable that represent the interest rate of a population, and for this case we know the distribution for X is given by:

$X \sim N(5.0,1.2)$

Where $\mu=5.0$ and $\sigma=1.2$

We are interested on this probability

$P(X\geq 3.5)$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X\geq 3.5)=P(\frac{X-\mu}{\sigma}\geq \frac{3.5-\mu}{\sigma})=P(Z\geq \frac{3.5-5.0}{1.2})=P(Z\geq -1.25)$

And we can find this probability using the z table or excel

$P(Z \geq$

Part b

We are interested on this probability

$P(X\leq 6.0)$

$P(X\leq 6.0)=P(\frac{X-\mu}{\sigma}\leq \frac{6.0-\mu}{\sigma})=P(Z\leq \frac{6.0-5.0}{1.2})=P(Z\leq 0.833)$

And we can find this probability using the z table or excel:

$P(Z \leq$

Part c

$P(3.5$

And we can find this probability on this way:

$P(-1.25$

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.

$P(-1.25$
