10 x 5 = 50
4 x 7 = 28
3 x 4 = 12 12/2=6
50+28+6= 84 square inches
Answer:
54.7%
Step-by-step explanation:
Given the function :
y=2700(0.453)
y represents an exponential Decay function because :
For a growth function ; the function :
y = A(1 + r) where, A is the initial amount and r = growth rate
With this function ; the value in bracket will always be greater Than 1
Hence, when the value after the initial value is less than 1 ; then we have an exponential Decay ;
Where
y = A(1 - r)
Hence, rate, r equals :
1 - r = 0.453
1 - 0.453 = r
r = 0.547
= 0.547 * 100%
= 54.7%
Answer:
k = -2.
Step-by-step explanation:
5(3 - 2k) = 2k + 39 Distribute the 5 over the parentheses:
15 - 10k = 2k + 39
15 - 39 = 2k + 10k
12k = -24
k = -2.
Solution: We are given:
Using the empirical rule, we have:
covers 68% of data.
Also the percentage of values below mean = Percentage of values above mean = 50%
Now, let's find the z score for x=20
Therefore, the percentage of values greater than 1 standard deviation above mean 
Expected number of students = 16% of 100 = 16
