Step-by-step explanation:
In ascending order
100 , 102 , 103 , 106, 109
No of data (N) = 5
Now
Position of median
= ( N + 1) /2 th item
=( 5+1 )/2 th item
= 6 / 2 th item
= 3rd item
Therefore exact median = 103
Hope it will help you :)
Answer:
1 =98
2 = 49
3 = 63
Step-by-step explanation:
Assuming 1 is at the center since it has the dot
<1 = arc 98
<1 = 98
We can find angle 2
<2 = 1/2 the intercepted arc
<2 = 1/2 (98)
<2 = 49
We can find angle 3
Angle formed by 2 chords
<3 = 1/2(arc 70 + arc56)
<3 = 1/2(70+56)
<3 =1/2 (126)
<3 = 63
Answer: the standard deviation of the means (D)
Step-by-step explanation:
Answer:
30 strawberry sundaes.
Step-by-step explanation:
We know there is a total of 70 sundaes.
3 sundaes will be strawberry.
4 sundaes will be choclate.
When you add 3 and 4 together, you get 7. This is your total ratio.
So 3/7 of the sundaes are strawberry.
And 4/7 of sundaes are choclate.
We know there is a total of 70 sundaes.
The total ratio we figured out is 7.
If the total sundaes is 70, and the total ration is 7. Then the total sundaes is 10 times bigger than the ratio.
This means we need to multiply the 3 strawberry sundaes and 4 choclate sundaes by 10.
3*10=30
4*10=40
So there are 30 strawberry sundaes and 40 choclate sundaes.
We need to find the strawberry sundae amount, so the answer is 30.
Hope this helps!
