The mean can be calculated by adding all of the values and dividing that sum by the number of values you added.  To take advantage of the way data is being collected, I am grouping the addends as, for example, 5(1), instead of writing out 1 + 1 + 1 + 1 + 1.

\A CLASS mean is:

B CLASS  mean is:

Based on these findings, we can conclude that the mean for Mrs. Ramos' class is about 2 more than the mean for Mr. McIntyre's class.

What is the value of x? Enter your answer in the box. 68mm 57mm 129.2mm
GarryVolchara [31]

Question:

What is the value of x? Enter your answer in the box. 68mm 57mm 129.2mm

The image of the triangle is attached below:

Answer:

The value of x is 98mm

Explanation:

It is given that VT = 57, TK = 129.2, YK = 68 and VK = x

Now, we need to find the value of x.

We shall determine the value of x, using angle bisector theorem,

\frac{YK}{TK} =\frac{YV}{VT}

Let us substitute the values, we get,

\frac{68}{129.2}=\frac{x-68}{57}

Switch sides, we have,

\frac{x-68}{57}=\frac{68}{129.2}

Multiply both sides by 57,

\frac{57(x-68)}{57}=\frac{68 *57}{129.2}

Simplifying, we get,

x-68=30

Adding both sides by 68, we have,

x=98

Thus, the value of x is 98mm

What are the values that satisfy the trigonometric equation for: 0≤q≤2π ?<br> sin(∅)+tan(−∅)
Mrac [35]

Answer:

First choice: 0, pi

Step-by-step explanation:

I am assuming the equation is

\sin q + \tan (-q) = 0

(the =0 part is missing in the original problem)

\sin q + \tan (-q) = 0\\\sin q + \frac{\sin (-q) }{\cos (-q)} = 0\\\sin q + \frac{-\sin q}{\cos q}=0\\\sin q = \frac{\sin q}{\cos q}\\\sin q \cdot \cos q = \sin q\,\,,\,\,\, 0\leq q \leq 2\pi\\\implies\\\cos q = 1 \implies q=\{0, 2\pi\}\\\mbox{or}\\\sin q = 0 \implies q=\{0, \pi, 2\pi\}\\\implies\\q=\{0,\pi,2\pi\}

So, the full solution for q is three values: 0, pi, 2pi. This matches the first choice (which is not complete, but that is ok)
