Answer:

  A.)  12

Step-by-step explanation:

The actual line of best fit places the value of y at about 11.95.

You can guess that the line of best fit will be between the lines of given points, tending toward below center at x=9 and above center at x=2. The answer choices 9, 17, and 1 are thus rendered untenable. The only one that makes any sense is (x, y) ≈ (9, 12).

Hello i need help on number 5,6,7 and also sorry about writing on it.i will mark as the brain thing
Ahat [919]
Ok I can help you on number 5 and 6. Sorry I dont understand number 7. You are correct on number six. There is not enough information because they do not say how many are 12 and how many are younger than 12. So on number 5 you would take 67 and divide it by 5. That is 13.4 so your answer for number 5 would be 13.4. Hope this helps!

Help please, which one is a quadratic expression?
Elza [17]

Answer: -6x^2 + 3 and 1 - 4x^2

Step-by-step explanation:

A quadratic expression is an expression that can be in the form ax^2 + bx + c, where a, b, and c are all constants, and a does not equal 0. (ax must be squared, it can't be raised to a power other than 2)

-6x^2 + 3 and 1 - 4x^2 can be in the form ax^2 + bx + c. Therefore, they are the quadratic expressions.

An airplane left airport A flying on a course of 72 degrees.
sweet [91]
<h2>Answer:</h2>

<em><u>Distance for which Aeroplane can be in contact with Airport B is =</u></em> <em><u>396.34 km</u></em>

<h2>Step-by-step explanation:</h2>

In the question,

We have an Airport at point A and another at point B.

Now,

Airplane flying at the angle of 72° with vertical catches signals from point D.

Distance travelled by Airplane, AD = 495 km

Now, Let us say,

AB = x

So,

In triangle ABD, Using Cosine Rule, we get,

cos(90-72) =cos18= \frac{AB^{2}+AD^{2}-BD^{2}}{2.AD.AB}

So,

On putting the values, we get,

cos18 = \frac{x^{2}+495^{2}-300^{2}}{2(495)(x)}\\0.951(990x)=x^{2}+245025-90000\\x^{2}-941.54x+155025=0\\

Therefore, x is given by,

x = 212.696, 728.844

So,

The value of x can not be 212.696 as the length of LB (radius) itself is 300 km.

So,

x = 728.844 km

So,

AL = AB - BL

AL = x - 300

AL = 728.844 - 300

AL = 428.844 km

Now, in the circle from a <u>property of secants</u> we can say that,

<u>AL x AM = AD x AC</u>

So,

428.844 x (728.844 + 300) = 495 x AC

441213.576 = 495 x AC

<u>AC = 891.34 km</u>

So,

<em>The value of CD is given by,</em>

CD = AC - AD

CD = 891.34 - 495

<u>CD = 396.34 km</u>

<em><u>Therefore, the distance for which the Aeroplane can still be in the contact with Airport B is 396.34 km.</u></em>

Explain when you know you need to rename a mixed Number to subtract.
Lady_Fox [76]
<span>You know that you need to rename a mixed Number to subtract when the numbers involved have different denominators. In such a case, the lowest common multiple (LCM) of the denominators must be calculated and subsequently used to adequately rename the mixed numbers before subtraction can be done.</span>
