Step-by-step explanation:
if you're looking for x
x=180-42-51= 87°
and if you're looking for D
D= 180-42= 138°
Answer:
Multiply row 1 by .
Step-by-step explanation:
The augmented matrix of the system of linear equation is described below:
Where , if we need to create , we need to multiply row 1 by , that is to say:
Hence, the correct answer is: Multiply row 1 by .
Answer:
The 99% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is
The sample mean is
The standard deviation is
Given that confidence is 99% then the level of significance is mathematically represented as
Next we obtain the critical values of from the normal distribution table
The value is
Generally the margin for error is mathematically represented as
=>
=>
The 99% confidence interval is mathematically represented as
=>
=>
Translate it 8units to the right then reflect it over the line y=-3
Why?
- We can see the Quadrilateral is in Quadrant 3.
- If we translate it by 8units right it come to Quadrant 4.
- Now reflect it over line y=-3
- we will get Quadrilateral 2
It seems like you've begun to apply the grouping method.
Because the two binomials in the parentheses are the same, we can rewrite this as
(5ab-4)(x+6)
(x+6) cannot be further factored. (5ab-4) cannot be further factored either.
Final answer: (5ab-4)(x+6)
