Answer:
OK SO IN MULTIPLYING INTEGERS
negative into negative is positive
positive into positive is positive
positive into negative is negative
Step-by-step explanation:
Answer:
2 = 65
1= 115
Step-by-step explanation:
angles 2 and 65° are equal
so input that in for 2
then subtract it by 180°
Step-by-step explanation: This simple confidence interval calculator uses a Z statistic and sample mean (M) to generate an interval estimate of a population mean (μ).
Note: You should only use this calculator if (a) your sample size is 30 or greater; and/or (b) you know the population standard deviation (σ), and use this instead of your sample's standard deviation (an unusual situation). If your data does not meet these requirements, consider using the t statistic to generate a confidence interval.
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
As you can see, to perform this calculation you need to know your sample mean, the number of items in your sample, and your sample's standard deviation (or population's standard deviation if your sample size is smaller than 30). (If you need to calculate mean and standard deviation from a set of raw scores, you can do so using our descriptive statistics tools.)
x=76
y=4
I think that answer should be right. Since it is isosceles the base angles will be the same and the top angle is an angle bisector which means that the angle split on top has even splits. Since no other side lengths- or any lengths at that matter- are give, it is safe to assume that y=4.
Answer:
x=3
Step-by-step explanation:
To solve for x in the given equation,follow the steps below.
2-(3x-4)=2x-9
clear bracket
2-3x+4=2x-9
6-3x=2x-9
collect like-terms
2x+3x=6+9
5x=15
divide bothsides by 5
