Answer: The proportion of oil tankers that had spills is \dfrac{156}{474} or 0.329.

Step-by-step explanation:

Since we have given that

Number of tankers is drawn = 474

Number of tankers did not have spills = 318

Number of tankers have spills = 474 - 318 = 156

Proportion of oil tankers that had spills is given by

\dfrac{Containing\ spill}{Total}=\dfrac{156}{474}=0.329

Hence, the proportion of oil tankers that had spills is \dfrac{156}{474} or 0.329.

Consider the incomplete paragraph proof.
Leya [2.2K]

The hypotenuse is c = a\sqrt{2}  times the length of each leg 'a'. Triangle XYZ is a isosceles right triangle, therefore the Pythagoras theorem becomes  and this can be evaluated by using properties of isosceles triangle.

According to the statement

we have given that a theorem and we have to prove it.

So, For this purpose,

The given information is :

Isosceles triangle XYZ where Angle X = 45^{0} Angle Y = 45^{0} Angle Z = 90^{0}

Let the sides of triangle XYZ be a, b, and c. Then side XY = c, YZ = b and ZX = a.

Now, it is given that triangle XYZ is isosceles triangle therefore, the shorter sides must be equal that is, a = b.

Now use Pythagoras theorem

a^{2} + b^{2} = c^{2}

But here a= b then the equation become

a^{2} + a^{2} = c^{2}

Then after solving it become

2a^{2} = c^{2}

And here we have to find the value of the hypotenuse,

so we solve it for c.

Then

c = a\sqrt{2}

From this it is clear that the

it can be concluded that the hypotenuse is  times the length of each leg 'a'.

What is the slope of the line shown?
koban [17]

Answer:

So buddy this is going to get a bad rating I know but I'm going to help you out as much as I can without seeing a picture so for linear equations the formula is y=mx+b anyways the slope is m and to find it, look at the line and see how many times it goes up till it lands on a correct point. once you have that you can see how many times it went up and over. Because your slope is your rise over run (rise/run) and so for example <em>if</em> it was c then it would be 3/3 meaning it goes up 3 and over 3. So to find the right one just find a starting point and see how much it goes over to the right. if it goes over to the left then its negative instead of run over to the right. And if it goes down instead of rise then its negative. Hope this helps you find your answer now and in the future.

Use the coordinates of the labeled point to find the point-slope equation of the line
koban [17]

Answer:

A. y + 1 = -2(x-2)

Step-by-step explanation:

point-slope equation is : y - y1 = m (x -x1)

remember m= slope value

the given point is (2, -1) therefore we can substitute the values in:

y + 1 = m(x -2)

now to make sure our answer is complete we will solve for the slope:

looking back at the graph, the y-intercept value is 3, therefore we have a point of (0,3) and (2, -1)

with any two points you can determine a slope.

y2 - y1 / x2 - x1

therefore :

-1 -3 / 2 - 0

-4 / 2 = -2

therefore our m value is -2

this makes the completed point-slope equation:

y + 1 = -2 (x - 2) or A
