Answer:
If the game with 3 hits is ignored the data becomes:
- 7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11
a) The mean will increase.
<u>With 3:</u>
- (3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9
<u>Without 3:</u>
- (7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21
b) The median will remain as is.
- With 3 and without the median is same = 9
Its 72.. its just 75/100 = x/96 then use cross products to find out that 74(96)=100x then solve to get 72
For every 4 white marables there are 9 black marables in the jar
Answer:
y = 36
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = - 18, z = 3 when x = 6 , then
- 18 =
( multiply both sides by 6 )
- 108 = 3k ( divide both sides by 3 )
- 36 = k
y =
← equation of variation
When x = 5 and z = - 5, then
y =
=
= 36
The value is 21 Because three represents those to variables which both equal to 21.
