Answer:
B or 31r-71
Step-by-step explanation:
First, use distributive property to expand the first term.
30r-66-(5-r)
Remove the parenthesis of the third term:
30r-66-5+r
Combine like terms
31r-71
Answer: 14
Step-by-step explanation:
- Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.
For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-
Given : Sample size : n-1
Then, the number of degrees of freedom the t-value will have :-
Hence, the t-value will have 14 degrees of freedom.
Answer:
∠SVU = 49°
Step-by-step explanation:
∠SVU is an inscribed angle and arc SU is the arc it intercepts
If you didn't know an inscribed angle is equal to half the measure of its intercepted arc.
Hence ∠SVU = arc SU / 2
if arc SU = 98
Then ∠SVU = 98/2 = 49
It's a pleasure to have you here in our class for this year! One thing you'll need to know for our Mathematics class is BIDMAS. BIDMAS is called the order of operations, which is how you'll be answering math problems. BIDMAS is short for Brackets, Indices, Division, Multiplication, Addition and Subtraction. This is the order that you will go through when you solve a math equation. For example, 3 x (3 + 7) - 4 2 /2. You'll first do the brackets.
= 3 x 10 - 42/2.
Then the Indices.
= 3 x 10 - 16/2
Since you have division and multiplication, you will do it from left to right.
= 30 - 16/2
= 30 - 8
Since you do not have any addition, you will do substraction next.
= 22
There you go! If you did it in order, you will get a different answer.
3x3 = 9 + 7 = 16 - 4 = 12 x 12 = 144/2 = 12...
(Hope I was right)
