Assume the readings on thermometers are normally distributed with a mean of 0degreesC and a standard deviation of 1.00degreesC.

faust18 [17]

Answer:

$P(-2.06$

And we can find this probability with this difference:

$P(-2.06$

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".

Solution to the problem

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

$X \sim N(0,1)$

Where $\mu=0$ and $\sigma=1$

We are interested on this probability

$P(-2.06$

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:

$P(-2.06$

And we can find this probability with this difference:

$P(-2.06$

# 1, 4, 6, 8, 9,11, 12, 13, 14, 16 pls pls help

ZanzabumX [31]

Answer:

i is equal to $\sqrt{-1}$ so separate the equations to $\sqrt{x} \sqrt{-1}$ then solve the $\sqrt{x}$ like you normally would then add i to the end replacint the $\sqrt{-1}$ here are the first few examples hope that helps!!

Step-by-step explanation:

1. $\sqrt{-1} \sqrt{36} \\6i$

4. $\sqrt{49} \sqrt{-1} \\2*7*I\\14i$

6. $-\frac{2}{3} \sqrt{9} \sqrt{-1} \\-\frac{2}{3} (3)(i)\\-2i$

8. $\frac{1}{3} \sqrt{25} \sqrt{-1} \\\\\frac{5}{3} i$

Matt saves 7 dollars every week in order to buy a guitar. Write an equation, using x for the independent variable and y for the

ANEK [815]

Answer:

y = 7x

y = $133

Step-by-step explanation:

x = independent variable

y = dependent variable

y = 7x

Where,

y = total amount saved

x = number of weeks

7 = constant

When x = 19

y = 7x

y = 7 * 19

y = 133

y = $133

Doug earns $10.50 per hour working at a restaurant. On

alexira [117]

First, add all of the working hours.
1 $\frac{3}{4}$ + 2 $\frac{1}{3}$ + 1 $\frac{5}{12}$

Since the denominators are different, make them all the same.
1 $\frac{9}{12}$ + 2 $\frac{4}{12}$ + 1 $\frac{5}{12}$

Add everything together.
4 $\frac{1}{12}$ + 1 $\frac{5}{12}$ = 5 $\frac{6}{12}$

Then, simplify.
5 $\frac{1}{2}$ or 5.5

Multiply the time by the salary.
<span>5.5*10.5= Doug earned $57.75</span>
