45th percentile means that 45% of the data fall below that number while 55% (that is, 100-45) fall above it.
Now, arranging the number in ascending order;
$60, $85, $95, $105, $120, $145, $155, $175, $190, $215, $235, $240, $260, $285, $325
The total number of counts = 15
Then,
Index = 15*45% = 15*0.45 = 6.75
Round up,
Index = 7
The,
7th number = $155
Therefore, 45th percentile value of the data = $155
Answer:
1) 0.00274
2) 0.872
3) 0.00240
Step-by-step explanation:
1) 365/(365×365) = 1/365
= 0.002739726027
= 0.00274 (3 sf)
2) (364/365)^50
= 0.8718182573
= 0.872 (3 sf)
3) [365 × (364^48)]/(365^50)
= 0.002401685062
= 0.00240 (3 sf)
Answer:
6/7
Step-by-step explanation:
When we divide by a fraction, it is the same as flipping and multiplying it.
Therefore, we have 3/5 * 10/7= 6/7

Angle X = 112 degrees, Angle Y = 123 degrees, Angle Z = 125.
Answer:
A) 39
Step-by-step explanation:
If you calculate the volume of the cube which is the V=a^3 you get 27, then calculating the pyramid, the Length is 3, and the Width is also 3. Then the height is 4. so you put that into the formula to calculate the volume which is V=L*W*H
--------
3
you get 12. Now its simple, you just add the 2 volumes, so you do 27+12 and its 39.
