Answer:
y= 2x
Step-by-step explanation:
The slope is 2
The y-intercept is zero because it intersects the origin so you do not need to right that.
Now just put it is slope-intercept form.
Hope you remember me because I just answered your other question 2 minutes ago! LOL :D
Can you please name me the brainiest in both of those answers. Thanks!
Answer:
A. The larger the sample size the better.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
We have to look at the standard error, which is:
This means that an increase in the sample size reduces the standard error, and thus, the larger the sample size the better, and the correct answer is given by option a.
Answer:
D.
Step-by-step explanation:
The given rational expression is
We obtain the quotient and remainder using synthetic division.
1 5 3 -10
-4| <u> -4 -4 4</u>
1 1 -1 -6
The quotient is and the remainder is -6.
The expression becomes;
Answer:
(a) z(105)= (105-95)/10
= 1
z(85)= (85-95)/10
= -1
P(85< x < 105) = P(-1< z < 1) = 0.6825
Quantity of people of 1600 that have IQ between 85 and 115 = 0.6825*1600= 1092
(b) z(105) = (115-95)/10 = 2
z(85) = (75-95)/10 = -2
P(-2< z < 2) = 0.6827
quantity of people of 1600 that have IQ between 75 and 115 = 0.6825x1600=1092
(c) Z(>125)=( 125-100)/10=3
Answer:b
