Answer:
Step-by-step explanation:
for this graph find rise over run , and where the line crosses they y axis.. sooo ..
it crosses at -2 and the slope is rise over run or y/x and I can see by the graph that the line goes up 1 when it goes over 1... so the slope is +1
sooo...
use the slope intercept form y = mx + b
y = 1x + (-2)
y = x - 2 :)
Answer: Population has a standard deviation of 32. What is the standard error f the sampling distribution if the sample size is 100?
Step-by-step explanation: Here we are told that a population has a standard deviation of 32 and that we have a sample of size 100 from this population that are asked for the standard error of the sampling distribution. Now it would be important to know what statistic we are taking from these samples. Now we would need to know what what statistic we're taking from these samples. Um I'm assuming that we're talking about sample averages in this case the standard error is well, let's sample averages are just distributed like this. They are so we have anna's big, which means that our sample averages are going to be approximately normally distributed. The mean of the sample averages will be equal to the mean of the population, and the standard air of the sample averages will be equal to the population. Standard deviation divided by the square root of the sample size. So this is our standard error of the sampling distribution, And so this is equal to 3.2. So that is your answer. That is the standard error of the sampling distribution. When the sample size is 100 is 32 I hope that helped
Hello!
Vertical angles are always congruent
This means that 3x - 35 = 130
We can solve this algebraically
3x - 35 = 130
Add 35 to both sides
3x = 165
Divide both sides by 3
x = 55
The angle AOB and AOC are supplementary which means they add to 180
First we have to find what angle AOB equals
3(55) - 35 = 130
We can subtract 180 by this number to get angle AOC
180 - 130 = 50
Angle AOC is 50
The answers are x = 55 and AOC = 50
Hope this helps!
Divide 3 by 8 (the fraction): 3/8=.375. Make into a percent: 37.5% or 38% (depending on what your teacher wants) and that's your answer :)
Answer:
x² + 10x - 24
Step-by-step explanation:
Given the roots are x = - 12 and x = 2 then the corresponding factors are
(x + 12) and (x - 2) and their product equals zero , that is
(x + 12)(x - 2) = 0 ← expand using FOIL
X² + 10X - 24 = 0
