Answer: 3
Step-by-step explanation:
Mean simply means average. To calculate mean,we add together all the numbers given and divide them by the amount of numbers.
The Mean here will be:
= [8 +(-10) + 7 + 10 + (-3) + 6]/6
=18/6
= 3
The mean is 3
16) First solve like a normal equation.
3|x/9| - 1 = 2
3|x/9| = 3
|x/9| = 1
Now just separate into two equations:
x/9 = 1
x/9 = -1
So x = 9, -9
17) Solve like normal:
-4 - 2|b - 10| = -6
-2 |b - 10| = -2
|b - 10| = 1
Now just separate into two equations:
b - 10 = 1
b - 10 = -1
So then b = 11, 9
Answer:
91 grams
Step-by-step explanation:
To get a percentage you go the number which you want the percentage of divided by the full number then multiply all that by 100. For example, (10 / 100) x 100 = 10, so 10 is 10% of 100.
Now lets call the answer x:
(x / 130g) x 100 = 30%
Now you need to get x on its own, so you need to rearrange it:
x = (30 x 130) / 100
When you change the sides, you change the signs.
With this equation we can work out what 30% of 130 is. So,
(30 x 130) / 100 = 39g
So, 39g is 30%. To find out how much sugar is in the diet juice you need to subtract this from the regular cranberry juice sugar:
130 - 39 = 91g
So there is 91 grams of sugar in a serving or diet juice.
Answer:
1.20($47.60)
Step-by-step explanation:
The quickest way to address this problem is to combine 1($47.60) + 0.20($47.60) into the simpler expression (1+0.20)($47.60), or
1.20($47.60).
We are not asked to find the final amount due, but it is $57.12.
F(6) = 6(5 - 6) = 6(-1) = -6
f(6.1) = 6.1(5 - 6.1) = 6.1(-1.1) = -6.71
f'(6) ≈ (-6.71 - (-6))/(6.1 - 6) = -0.71/0.1 = -7.1
