Answer: i think its 65n
Step-by-step explanation:
The length of each interval would be 3.75 rounding to whole number is 4.
Step-by-step explanation:
- Stack in excel from lowest to highest points.
- Total number of data points are 14.
- Frequency distribution to be created.
- You can use countif function for frequency distribution.
- Since we have already got the number of intervals.
- It will be easier to calculate the number if intervals.
- normally there should be 5-15 intervals to get a better histogram.
- Basic formula is Highest data point - Lowest data point/ classes/intervals.
- So (29-14)/4 = 3.75 rounding to 4.
Answer:
Step-by-step explanation:
∠D = ∠B {opposite angles of parallelogram are equal}
∠D = 40°
In ΔDCA
∠DCA + ∠D + ∠CAD = 180 {Angle sum property of triangle}
57 + 40 + ∠CAD = 180
97 + ∠CAD = 180
∠CAD= 180 - 97
∠CAD = 83°
Answer:
x = 0, y = -7
Step-by-step explanation:
x - 4y = 28
-4x - y = 7
____________
x - 4y = 28
-16x - 4y = 28
____________ _
17x = 0
x = 0
0 - 4y = 28
y = -7
