Answer:
q = 
Step-by-step explanation:
Given
t = 
+ 
Multiply through by pq to clear the fractions
tpq = q + p ( subtract q from both sides )
tpq - q = p ← factor out q from each term on the left side
q(tp - 1) = p ← divide both sides by (tp - 1)
q =
24 cookies
dean ate 8 cookies
elise ate 4 cookies
clark ate 6 cookies
Step-by-step explanation:
i am pretty sure this is correct
make a diagram of a circle with twelve spots
change 1/3 to 4/12, so color in 4 spots for dean
multiplie 1/4 times 8/12 ( the remaining spots), color in that number of spots for elise
do the same with 1/2, color in the amount of spots for clark
you will have 3 spots left, meaning each spot is worth 2 cookies
multiplie the number of spots times two to get your answer for each person
Answer:
3.5
Step-by-step explanation:
26, 31, 32, and 39
First we need to find the mean
(26+ 31+ 32+ 39) /4
128/4 = 32
The mean absolute deviation is sum of the positive difference between the number and the mean divided by the number of terms
((32-26)+ (32-31)+ (32-32)+ (39-32)) /4
14/4
3.5
Answer:
15
Step-by-step explanation:
Finding total number of pupils(y)
3/y x 360°=27°
3x360°/y=27°
1080°/y=27°
1080°=27°y
1080°/27°=27°y/27°
40=y
Number of pupils who said that Maths was their favorite (z)
z/40x360°=135°
360°z/40=135°
360°z=135°x40
360°z=5400°
360°z/360°=5400°/360°
z=15
