Jamal has the better record. After comparing the too Jamal made his free throw 77% of the time. Brian on the other hand made his free throws only 62.5% of the time.
Let the common difference between 2 consecutive pizzas be x.
The pizza is cut into slices of
90°, 90°-x, 90°-x-x, 90°-x-x-x, 90°-x-x-x-x, 90°-x-x-x-x-x,
that is
90°, 90°-x, 90°-2x, 90°-3x, 90°-4x, 90°-5x
the sum of these angles is 360°, so:
90°+90°-x+90°-2x+90°-3x+90°-4x+90°-5x=360°
90°*6-15x=360°
540°-360°=15x
180°=15x
x=12°
The degree measure of the fifth slice is 90°-4x=90°-4*12=90°-48=42°
Answer: 42°
Answer:
(i)(a - 2y) (3x - 4b)
(iii) (m - n)(m + 4)
Step-by-step explanation:
(i)
3ax - 6xy + 8by - 4ab
= 3x (a - 2y) - 4b (-2y + a)
= 3x (a - 2y) - 4b (a - 2y)
= (a - 2y) (3x - 4b)
(iii)
Answer:
Option a
Step-by-step explanation:
Given two normal distribution samples
I group has 106 as mean and 8.5 as std deviation with sample size = 60
II group has 121 as mean and 6.3 as std deviation with sample size =38
We find mean difference =-15
For margin of error finding, we have to find the combined std error for the difference
Variance of difference = Sum of variances
STd error for difference = 1.50
Hence for 99% margin of error =2.58(1.50)
= 3.87
