Answer:
Zeroes are: (-6, 0) and (2.5, 0)
x= -6 & x= 2.5
Step-by-step explanation:
I recommend using desmos for graphing problems!
Answer:
It's A 7^7
Step-by-step explanation:
This is because if two numbers with the same base divide,we subtract the exponent of the divisor from that of the dividend
You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3
Answer:
d. 200 and 2
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
Mean = 200
Standard deviation = 18
Sample size: 81
Standard error: 
So the correct answer is:
d. 200 and 2
