like you see, there are 2 line on the triangle.
68° is looking in front of one line, so the other line's front have to be 68°
now we found 2 corner of triangle.
a triangle's sum of interior angles equal to 180°
68°+68° = 136°.
now i have to remove 136 from 180 to find our x
180°-136° = 44°
x = 44°
good luck(:
Answer: The answer is A) 2xyz^2
Step-by-step explanation: I used a math website
To turn a decimal into a percent you simply multiply it by 100
to turn a percent into a decimal, you would remove the percent symbol and move the decimal point two place to the left (make sure you add zeros as needed)
hope this helps! :)
Answer:
The teacher select a sample of n =15 students. And he wanted to know if teaching a smaller class was more effective and students performed better, that means if 
and he obtaind a sample mean of 
.
Based on this the correct system of hypothesis are:
Null hypothesis: 
Alternative hypothesis:
And the best option for this case is:
a. H0:
vs. H1:
.
Step-by-step explanation:
For this case we have the following previous info given:
represent the true mean
represent the true deviation

Answer:
no
Step-by-step explanation:
In a function, each "x" value [input] must have only one corresponding "y" value.
We know that points are written as (x, y)
Our points: {(3,-2), (1, 2), (-1,-4), (-1, 2)}
We can see that the x-input of -1 has two y-outputs, so this is therefore not a function
hope this helps! have a lovely day :)
