Answer:
6x
6x(x + 4)
Step-by-step explanation:
Both 6x^2 and 24x are divisible by 6x
Answer:
81 degrees
Step-by-step explanation:
A quadrilateral has four interior angles which sum up to 360 degrees.
As we are given that two angles are right angles which means the sum of two angles will be 180 degrees and the third angle is 99 degrees.
As we know that the four angles sum up to 360 degrees.
Let A,B,C and D denote the four angles,
Then
Sum of angles = 360
A+B+C+D=360
90+90+99+D=360
279+D=360
D=360-279
D= 81 degrees
So the fourth angle is 81 degrees ..
Answer:
2
Step-by-step explanation:
Solve. To do so, change the division sign into a multiplication sign, and flip the second fraction:
(2/3)/(1/3) = (2/3) x (3/1)
Multiply across:
(2 * 3)/(3 * 1) = (6)/(3)
Simplify:
6/3 = 2
2 is your answer.

Step-by-step explanation:
Answer:
(a) The sampling distribution of
= Population mean = 79
(b) P ( greater than 81.2 ) = 0.1357
(c) P ( less than or equals 74.4 ) = .0107
(d) P (77.6 less than less than 83.2 ) = .7401
Step-by-step explanation:
Given -
Sample size ( n ) = 81
Population mean 
= 79
Standard deviation 
= 18
(a) Describe the sampling distribution of
For large sample using central limit theorem
the sampling distribution of = Population mean = 79
(b) What is Upper P ( greater than 81.2 ) =
= 
= 
= 
= 1 - .8643 =
= 0.1357
(c) What is Upper P ( less than or equals 74.4 ) =
= 
= 
= .0107
(d) What is Upper P (77.6 less than less than 83.2 ) =
= 
= 
= 
= 0.9821 - .2420
= 0.7401
