Answer:
x=4
Step-by-step explanation:
Since both triangles are similar, you can make an equation 12/5x-2 = 16/6x. When you cross multiply you get 72x=80x-32. Then you transfer the 80x and you get -8x = -32. Then you divide by -8 and you get x=4.
Answer:
Your answer is 0 (zero).
<u>Step</u><u> </u><u>by</u><u> </u><u>Step</u><u> </u><u>Explanations</u><u>:</u>
<u>For</u><u> </u><u>mean</u><u>:</u>
1. Add all the numbers; which is 90
2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15
3. Your mean is 15
For Median:
1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22
2. Find the middle number(s), which are 12 &18
3. Add; 12 + 18 = 30
4. Divide; 30/2 =15
5. Your Median is 15
So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0
Answer: P (3 or 9) = 1/6
Step-by-step explanation:
Concept:
Here, we need to know the idea of probability.
Probability is a measure of the likelihood of an event to occur.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
The numbers on a dice: 1, 2, 3, 4, 5, 6
Total numbers = 6
Number of 3 = 1
Number of 9 = 0
P (3 or 9) = Favorable / Total (refer to the attachment below)
P (3 or 9) = (1 + 0) / (6)
P (3 or 9) = 1 / 6
Hope this helps!! :)
