If 7 is the mean of 10,3,4,a,6,9 and 10.find the value of a
nydimaria [60]

Answer:

a = 7

Step-by-step explanation:

I think, what you need to do, is first understand how to find the mean of anything: It's quite simple, actually, just add up all the numbers, then divide that number by the number of numbers. So, let's put it in perspective:

10, 3, 4, a, 6, 9, 10

7 is the mean. 7 is the number of numbers.

If, to find the mean is: 10 + 3 + 4 + a + 6 + 9 + 10= 7a ÷ 7, then: 10 +3 + 4+ 6 + 9 +10= 42

42 plus what divided by 7 is the question now.

42 + a ÷  7= 7

So, 7 times 7, that's 49 minus 42 and you've got your answer: 7

How to do the problem
trapecia [35]

Step-by-step explanation:

g(0.5) = 2 \\  \\ h(x) = g(x).f(x) \\  \therefore \: h(2) = g(2).f(2) \\  \therefore \: h(2) = 5 \times 2\\ \therefore \: h(2) = 10\\  \\ \\  j(x) = g(x) - f(x) \\  \therefore \: j(4) = g(4) - f(4) \\  \therefore \: j(4) = 9 - 8\\ \therefore \: j(4)  = 1\\  \\  \\
