Horrible wording but I'll say 0 squared and 1 squared
Answer:
Correct choice is A
Step-by-step explanation:
Two vertices of the rectangle have coordinates A(-1, 5) and B(2, 1). If rectangle sides are parallel to the axes, then two remaining vertices have coordinates C(-1,1) and D(2,5) (see attached diagram for details).
Find the length and the width:
Then the length is 1 unit longer than the width.
Answer:
Mean is 0.6.
Standard deviation is 0.059
Step-by-step explanation:
The first step is finding the sample proportion p.
Suppose Maria, a researcher, takes a random sample of 70 Americans and finds that 42 are over the age of 20.
This means that
What are the mean and standard deviation of the sampling distribution of p?
Mean:
The mean of a proportion is the same as the proportion. So the mean is 0.6
Standard deviation:
Proportion p in a sample of size n. The standard deviation is:
Sample size 70, so:
Answer:
x = 2.5
Step-by-step explanation:
In order to solve for x, we need to write an equation. This question gives us the angles of a triangle, so we can use this to write our equation. All angles of a triangle will always add to 180 degrees, therefore:
(12x+6) + 104 + 40 = 180
Now we can just take out the brackets, combine like terms and isolate and solve for x:
12x + 6 + 104 + 40 = 180
12x + 150 = 180
12x + 150 - 150 = 180 - 150
12x = 30
12x/12 = 30/12
x = 2.5
Hope this helped!
Grace should have added 58 instead of subtracting
