The number of students with heights less than 163 cm should be expected is 12.

According to the statement

The mean of height is 175 cm

and  the standard deviation of height is 6 cm.

We use normal distribution here with formula

Z= X - μ /σ

Here X is 167.5 and μ is 175 and σ is 6 cm.

Substitute the values in it then

Z = 167.5 - 175 / 6

Z = -1.25

-1.25 have a p value 0.012

Out of 1000 students:

0.012 x 1000 = 12.

So, The number of students with heights less than 163 cm should be expected is 12.

Find the bearing of the ship. Round to the nearest tenth of a degree if necessary.

Answer:

  117°

Step-by-step explanation:

We assume you want to report your bearing as an angle measured CW from North. For conventional angles greater than 90°, it will be ...

  450° -angle = 450° -333° = 117°

The bearing of the ship is 117°.

Answer:

$60

Step-by-step explanation:

So from the question, we need to find the fixed amount for the tv's. So we have to make an equation, and don't forget to add the extended warranties:

11(x + 25) = 935

x will represent a tv, and the 25 is the extended warranty for a tv, since the questions states 11 tv's with warranties is 935, the equation will look like that. Now lets slove:

11(x + 25) = 935

multiply

11x + 275 = 935

subtract 275 from both sides

11x = 660

divide both sides by 11

x = 60, each tv is $60

Yes algebra!!! Anyways, the m of y=mx+b is the slope of the graph, this affects the graph by making the line go in a angle either negatively or positivly
B is where the plot lies on the y line (up and down)

Helpp please!! 10 points
Zolol [24]
Slope is 1.3

take your 2 points and make a triangle, then count the small boxes to the point in the middle where they met. ( REMEMBER THE X&Y RULES)
you should get 4/3, you need to divide and put it into decimal form.
GOOD LUCK! :))

Calculate the distance between each given pair of points. Round your answer to the nearest tenth, if necessary.
Ksju [112]
The answer is 5 

Here are the steps:

First off, we will be using the distance formula of 
d=\sqrt{(x_ {2}- x_{2}) ^{2}+( y_{2}- y_{1})^2     }

So we have the ordered pairs of (3,1) and (6,5)

Once you plug them into the formula it should look like this: 
d= \sqrt{(6-3)^2+(5-1)^2}

Now we do the math inside the parenthesis and end up with:
d=\sqrt{3^2+4^2}

Then you multiply by the power and simplify to get:
d=\sqrt{25}

And the \sqrt{25}=5

So your answer is 5
