Since we can add a number to a tens number easily, we make one of the addends a tens number when solving an addition problem.
Example 1:
Add 9 and 6.
9 + 6 = 9 + (1 + 5)
= (9 + 1) + 5
= 10 + 5 = 15
Note that adding 10 and 5 is much easier than adding 9 and 6.
Example 2:
Add 18 and 16.
18 + 16 = 18 + (2 + 14)
= (18 + 2) + 14
= 20 + 14 = 34
Note that adding 20 and 14 is much easier than adding 18 and 16.
Answer:
20
Step-by-step explanation:
y=kx
24=6k
k=4
y=4*5=20
I would assume all of them since they are all the same, here is an example of exponential decay : Write an equation for the following statement, Merida has has $200,000 in a stock market which is decreasing by 1% annually.
f(x) = 200000(.99)^2
Comment if you need me to explain why this is the equation
Answer:
a = 
Step-by-step explanation:
4a -16 = a - 15
both left and right -a
then
4a - 16 -a = a - 15 -a
then
4a -a -16 = a -a -15
then
3a -16 = -15
both left and right + 16
then
3a -16 + 16 = -15 + 16
then
3a = 1
both left and right ÷3
then
3a ÷ 3 =1 ÷ 3
then
a =
<span>This is a matter of knowing the formulas involving the binomial distribution:
Mean = n*p = 125*0.46 = 57.5
Variance = n*p*(1-p) = 125*0.46*(1-0.46) = 125*0.46*0.54 = 31.05
Standard Deviation = sqrt(Variance) = sqrt(31.05) = 5.572252686</span>
