Answer:
Step-by-step explanation:
mode means most repeated number . here in this given data 7 is repeated maximum number of times . so mode is 7.
to find median arrange the data from ascending to descending order.
Data = 1,2,3,4,5,7,7,7,8,8
median = N + 1/2 (N means no of data )
=10 + 1/2
=11/2
=5.5
= 5th term + 6th term/2
=5+7/2
=12/2
=6
mean = sum of data / no of data
=3+7+2+4+7+5+7+1+8+8/10
=52/10
=5.2
range = largest value - smallest value
=8 - 1
=7
Answer:
B
Step-by-step explanation:
the mean is calculated as
mean = 
this year's mean = 
= 
= 4.1
last year's mean = 
= 
= 3.1
difference = 4.1 - 3.1 = 1
Answer:
The standard form of the equation of y = -1/4x - 2 is x + 4y = -8 which is C
Answer:
The correct answers are
angle 1 and angle 4
angle 3 and angle 7
Step-by-step explanation:
From the given figure we can see that,
b and c are parallel lines.
The correct answers are,
<u>1). angle 1 and angle 4</u>
Angle 1 and 4 are vertically opposite angles. Vertically opposite angles are equal.Therefore angle 1 congruent angle 4
<u>2). angle 3 and angle 7</u>
angle 3 and angle 7 are corresponding angles on same side which are equal. Therefore angle 3 congruent angle 7
Answer:
26 and 32. The product (multiplied together) is 832.
