you need to find the mean on these numbers that is step one in finding standard deviation. so this is 44.2. now you need to subtract the mean from each number and square the result. after that step you now have these numbers.... 3.24, 139.24, .64, .4,.64,282.24,116.64,77.44,27.04. now the next step is to find the mean of these numbers. you get 71.9 appx.. now all you do is square root this number you get 8.5 when you round to the nearest thenth

svetlana [45]

Answer:3 cups of seeds and 2 tablespoons of maple syrup

-OR-

6 cups of seeds and 4 tablespoons of maple syrup

Step-by-step explanation:

As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"

The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"

Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.

<h2> Question # 4</h2>

4. Multiple Representation Write a different equation to find the angle measures in Example 2. Will the answer be the same? Explain.

As we know that the sum of angles of a triangle is 180⁰.

In Mathematics, an equilateral triangle:

  • is said to be a triangle in which all three sides are equal.
  • All three internal angles of an equilateral triangle are also congruent to each other, each having 60° measure.

From the given equilateral triangle, the equation can be written as:

x + x + x =  180⁰

As each angle is 60°.

so

60° + 60° + 60° = 180⁰

Therefore, each angle measure = x = 60°.

Yes! the answer is same, as the sum of angles of a triangle is 180⁰. The reason is that an equilateral triangle is said to be a triangle in which all three sides are equal. All three internal angles are also congruent to each other, each having 60° measure.

<h2>                         Question # 5</h2>

5. Draw Conclusion Triangle ABC is a right triangle. What conclusion can you draw about the measure of the angles of the triangle.

  • A right triangle, let say ∠ABC, has two legs and a hypotenuse. The two legs meet at right angle - or 90° angle.
  • The longest side is called the the hypotenuse is the longest side of the right triangle which is the opposite the right angle.

The Pythagorean Theorem defines the relationship in every right triangle such as:

              a^2+b^2=c^2

A right isosceles triangle - having two same sides - has a 90° angle and two  90° angles.

Another kind of right triangle is the 30-60-90 degree triangle. Where one angle is right, 90°, and other two angles are 30° and 60°.

Another kind of right triangle is the 45-45-90 degree triangle. Where one angle is right, 90°, and other two angles are 45° and 45°.

So, we conclude that we have a variety of right triangles where one angle is the right angle, measuring 90° angle.

What is an statistics
Vlad [161]

Hello There!

Statistics is a tool used to help people process, summarize, analyze and interpret data for making better decisions.

It helps us with future events if we know what has happened in past.

Helps us make better decisions.

The better we know about the future of an outcome, the more possibility we have to work around it.
