ANSWER
C. 7
EXPLANATION
We want to evaluate
We use the order of operations PEDMAS.
Dealing with the parenthesis first,we have
Note that:
and
Our expression now becomes:
Next, we add to get:
We finally subtract to get,
The correct answer is C
Answer: The mean of the data set is 25.
Step-by-step explanation:
To calculate the mean of a data set, first add up all the values.
17 + 34 + 19 + 27 + 30 + 23 = 150
Then divide the sum by the amount of values in the data set. Our sum here is 150 and the amount of data values is 6.
150 ÷ 6 = 25
Answer:
Step-by-step explanation:
We have two points
(
6
,
8
)
and
(
−
2
,
0
)
Explanation:
To find number of points of intersection, we should solve these pair of equations.
As
y
=
x
+
2
, we have

or

(

)
=
0
or
(
x
−
6
)
(
x
+
2
)
=
0
and hence
x
=
6
or
−
2
putting these values in
y
=
x
+
2
, we get
y
=
8
or
0
Hence, we have two points
(
6
,
8
)
and
(
−

,
0
)
