Mean is the average of the data set, which is found by adding all values together and then dividing that sum by the number of data values.
Median is the middle number of the data set, and can be found by ordering the values from least to greatest. If there are two middle numbers, the average of the two would be the median.
Mode is the number that shows up most frequently in the data set.
Range is found by subtracting the lowest number from the highest number in the data set.
<u>Set 1</u>
Mean:
18+20+22+11+19+18+18=126
126÷7=18
Median:
11, 18, 18, 18, 19, 20, 22 → 18
Mode: 18
Range: 22-11=11
<u>Set 2</u>
Mean: 23+27+24+26+26+24+26+24=200
200÷8=25
Median:
23, 24, 24, 24, 26, 26, 26, 27 → 24+26=50 → 50÷2=25
Mode: 24 and 26
Range: 27-23=4
There are 2 dollars so that would equal 20 dimes.
Proof:
10 cents = a dime
20 x 10 = 200 = 2 dollars
__
There are 35 cents to that would equal 3 dimes and 1 nickel.
Proof:
10 cents = a dime
5 cents = a nickel
3 x 10 = 30
1 x 5 = 5
__
So the final answer would be 23 dimes and 1 nickel.
<h2>PLEASE MARK ME AS BRAINLIEST</h2>
the number of small cars rented is 6.
The number of large cars rented is 8.
Step-by-step explanation:
Step 1 :
Each small car can hold = 5 people
Each large car can hold = 8 people
Step 2 :
Number of small cars rented = x
Number of large cars rented = x + 2
Step 3 :
Altogether the total cars can hold 94 people.
Total people = 5 people (No. of small cars) + 8 people (No. of large cars)
94 = 5 (x) + 8 (x+2)
94 = 5x + 8x + 16
78 = 13x
x = 78/13 = 6
∴ Number of small cars, x = 6 small cars
Number of large cars, x+2 = 8 large cars.
Answer:
x=55°
Step-by-step explanation:
x=90-35
x=55°
(because its x+35=90°)
The prallelogram whose adjacent sides are equal and one vertex angle is 90 degrees is a square.
The value of angle 1 is 90 degrees as the diagonal of the square intersect at 90 degrees.
The value of y is 23.
The diagonal of the square bisect the vertex angle hence the angle of 3x is 45 degrees.
Thus, the value of x is 15 degrees.
The value of 12z is 45 degrees.
Thus, the required value of z is 3.75 degrees.
