Well first you take 17 and you then take 14 and 19 and you add that all together and you get 50 then you divide 50 in divide that by 3 and you get 16.6
Answer:
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation
In this problem, we have that:
So
3.
Let the points be A, B & C.
The three distinct segments are AB, BC & AC.
Answer:
false
Step-by-step explanation:
<u>Step :1</u>
Given x- 2 y =5 .......(1)
put x=1 and y= -3 on left hand side of given equation
1 - 2 (-3) = 5
1 + 6 = 5
7 ≠ 5
both sides are not equal
so it is false
Answer:
Step-by-step explanation:
13x^2 + 56x + 75 = 4x^2 - 10x - 46
You need to first combine like terms, so subtract 4x^2 from both sides,
9x^2 + 56x + 75 = -10x - 46
then add -10x to both sides
9x^2 +66x + 75 = -46
then add -46 to both sides
9x^2 + 66x + 121 = 0
Then use the quadratic formula,
So
a = 9
b= 66
c = 121
That simplifies to
Which simplifies to
