Considering the first equation 15 × 0 = -36 + a
15 × 0 = 0
therefore, -36 + a =0
In the second equation
24 × 8 × 0 = 36 - b
Consider the LS
24 × 8 × 0 = 0
Therefore, 36 - b = 0
we are left with the two equations,
36 - b = 0
-36 + a = 0
then, we calculate the number that can be substituted to satisfy the two equations.
solving the equations
b = 36, and a = 36
Therefore, 36 is the number that can be used to substitute a and b in the equations
Answer:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
In a sample of 234 individuals over the age of 25, chosen at random from the state of Oregon, 48 did not have a high school diploma.
This means that 
The upper limit of this interval is:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
Answer:
if m is midpoint then AM=BM
11X-9=7x+35
4x=44
x=11
AM=11×11-9 =121-9=112
BM=112
Answer:
The laws of indices enable expressions involving powers to be manipulated more efficiently than writing them out in full. Using indices An index, or power, is the small floating number that appears after a number or letter. The plural of index is indices. Indices show how many times a number or letter
Step-by-step explanation:
Answer:
4x+3−9x= 3-5x
5+3.2n−6−4.8n= -1.6n-1
2y−5(y−3)= -3y-15
−1/2(8b+3)+3b= -1b-1.5
Step-by-step explanation:
Add the numbers with the variables.
4x-9x= -5x
Then add the rest of the equation to it.
3-5x
Again, add the numbers with the variables and simplify the others.
3.2n- 4.8n= -1.6n
5-6= -1
That leads to....
-1.6n-1
Distribute the 5 into the parenthesis.
2y-5y- 15
Now, subtract the variables.
-3y-15
Distribute into the parenthesis.
-4b+(-1.5)+ 3b
Add the variables together.
-1b-1.5
