Answer:
A
Step-by-step explanation:
The mean is a good measure of central tendency because it takes into account all of the data compared to other. One of the instance where the mean is not good measure is when there are outliers ( extreme values) in the data in this case the median is better. In the scenario in the question the data set is nearly symmetrical therefore the mean is best central tendency measure to use
Answer:
No
Step-by-step explanation:
in order for a slope to be perpendicularit needs to me the opposite recipricol
so to be perpendicular to 3/2 it would be -2/3
Answer:
The percentage increase in Jayana's postcard collection is 15%
Step-by-step explanation:
Jayana had 20 postcards last year
With 3 more postcards this year
From the given equation Quantity = Percent x Whole
Here;
Let P = Percent/100%
Quantity = Increment in postcard = 3 postcards
Whole = The total postcards from last year = 20 postcards
Hence,
3 postcards = P x 20 postcards
P = 3/20 = 0.15
Recall P = Percent/100%
∴ Percent = P x 100% = 0.15 x 100% = 15%
The percentage increase in Jayana's postcard collection is 15%

Answer:
1.180
2.50
3.56
Step-by-step explanation:
M<4,M<2 and M<5 have to add up to 180 as a result of being a parallel line.
Making m<2 50 since 46°+84=130, 180-130=50.
Since m<1 is 74 and knowing m<2 is 50 74+50=124 180-124=56 m<3=56
Therefore 1,2,3 =180°
