Answer:
0.19706
Step-by-step explanation:
-Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:
Hence,the probability that an employee makes between $70,000 and $80,000 is 0.19706
Answer:
I would assess what type of learner my student was by seeing which form of teaching they respond best to. I would try to cover all 7 types of learning by going through different examples. I would lead by explaining the concept and then start to work through at least 3 examples. I would then ask them to finish certain parts and eventually watch them work one out on their own. One of the key things I would make sure to do is personalize the learning experience. I would offer stories and situations that they may be able to relate to or remember when completing the problem.
I think it is 3.6 .......
Answer:
7. x = 37.5
8. x = 8
Step-by-step explanation:
7. The sides of the triangles are proportional, therefore:
x/20 = (46 - 16)/16
x/20 = 30/16
Cross multiply
x*16 = 30*20
16x = 600
Divide both sides by 16
x = 600/16
x = 37.5
8. The sides of the triangles are proportional. Therefore,
(7x - 1)/22 = (3x + 1)/10
Cross multiply
10(7x - 1) = 22(3x + 1)
70x - 10 = 66x + 22
Collect like terms
70x - 66x = 10 + 22
4x = 32
4x/4 = 32/4
x = 8
