Step-by-step explanation:
Probability of being left handed = 0.13
Probability of being not left handed = 1-0.13 =0.87
They select a sample of five customers at random in their stores
a. The first lefty is the fifth person chosen
Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]
b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]
c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]
d)
[tex]P(x=3)=^5C_3 (0.13)^3 (0.87)^2=\frac{5!}{3!2!}(0.13)^3 (0.87)^2=0.0166[/tex]
e)
[tex]P(x\geq 3)=P(x=3)+P(x=4)+P(x=5)\\P(x\geq 3)=\frac{5!}{3!2!}(0.13)^3 (0.87)^2+\frac{5!}{4!1!}(0.13)^4(0.87)^1+\frac{5!}{5!0!}(0.13)^5 (0.87)^0=0.01790[/tex]
f)
[tex]P(x\leq 3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]
[tex]P(x\leq 3)=\frac{5!}{0!5!}(0.13)^0 (0.87)^5+\frac{5!}{4!1!}(0.13)^1(0.87)^4+\frac{5!}{2!3!}(0.13)^2 (0.87)^3+\frac{5!}{2!3!}(0.13)^3 (0.87)^2=0.9987[/tex]

I am a multiple of 6. I am also a multiple of 4. I am less than 30.
Who am I?
Answer:
12 and 24
Step-by-step explanation:
First, we need to list out the common multiples of 4 nd 6, less than 30
[tex]4 = 0.4,8,12,16,20,24,28[/tex]
[tex]6 = 0.6,12,18,24[/tex]
Then, we list out the common multiples
[tex]Common\ Multiple = 12,24[/tex]
Since, only 12 and 24 fall in this category.
Then the number is either 12 or farm

The beginning balance of Keyshawn's savings account for the month of September was $3900, and it remained this way for the first 11 days of the month. On September 12, Keyshawn made a withdrawal of $700, so his balance changed, and it remained the same for a total of 9 days. On September 20, Keyshawn made a deposit of $1500, so his balance changed again, and it remained the same for a total of 10 days to finish out the month. Keyshawn's savings account has an APR of 3.65%, calculates interest daily, and pays interest at the end of the month. Keyshawn wants to calculate the amount he earned in interest during the month of September.
Part I: What interest rate does Keyshawn's savings account pay per day?
Part II: How much did Keyshawn earn in interest during the first 11 days of September?
Part III: How much did Keyshawn earn in interest during the next 9 days of September?
Part IV: How much did Keyshawn earn in interest during the last 10 days of September?
Part V: How much did Keyshawn earn in interest during the month of September?
Answer:
1. 3.65%
2. 14,235
3. 49402.75
4. 185,795.04
5. 181,895.0375

Answer:
144.21
Step-by-step explanation:
Use Distributive Property to multiply the parentheses.
3.7 ⋅ 42.3 = 156.51
3.7 ⋅ 24.6 = 28.3
Your equation should look like this now:
8^2 ÷ 4 + 156.51 - 28.3
8 to the second power is 64
64 ÷ 4 + 156.51 - 28.3
Divide:
64 ÷ 4 = 16
Equation:
16 + 156.51 - 28.3
Add.
16 + 156.51 = 172.51
Equation:
172.51 - 28.3
Subtract.

Solve using substitution y=3x+2, y=7x-6
Answer:
x=2, y=8 or (2, 8)
Step-by-step explanation:
y=3x+2
y=7x-6
substitute y=7x-6 into y=3x+2
7x-6=3x+2
4x=8
x=2
then plug 2 into either one
y=7(2)-6
y=8

The length of a rectangle is four times its width. if the perimeter of the rectangle is 90 cm, find its length and width
Answer:
length 36, width, 9.
Step-by-step explanation:
you are trying to find "X" and it's 4 times the size of y, the whole thing is equal to 90. it would look like this
y=4x
y(4x) + x = 90
5x=90
90/5= 18
the rest is the "y" value, 72.
divide both by 2 because rectangles have 4 sides, and you get the answer above.

In 1998, the population of country C was 38 million, and the exponential growth rate was 1% per year
Answer:
Step-by-step explanation:
Formula for the exponential graph is given by the function,
[tex]P(t) = P_0(1 + r)^t[/tex]
Where [tex]P(t)[/tex] = population after 't' years
[tex]P_0[/tex] = Initial population
r = rate of increase
t = Number of years
In 1988, population of a country C was 30 million.
A). Function for the population will be,
[tex]P(t)=38(1+0.01)^t[/tex]
[tex]=38(1.01)^t[/tex]
B). Population in year 2020,
[tex]P(22)=38(1.01)^{22}[/tex]
= 47.30 million
C). Doubling time means the duration in which [tex]P_0[/tex] becomes [tex]2(P_0)[/tex].
[tex]P(t)=2P_0[/tex]
[tex]2P_0=P_0(1.01)^t[/tex]
[tex](1.01)^t=2[/tex]
By taking log on both the sides of the equation,
t[log(1.01)] = log2
t = [tex]\frac{\text{log}(2)}{\text{log}(1.01)}[/tex]
= [tex]\frac{0.30103}{0.004321}[/tex]
t = 69.66 years

If the value of two integers differs by 3, and the product of the two integers is 108, what is the sum of the two integers?
A.21
B.19
C.25 D.23
Answer:
A
Step-by-step explanation:
Let the smallest number be n.
If the next integer differs by 3 then:
n + 3 is our second integer.
If the product is 108 then we would multiply them together.
n * (n + 3) = 108 Now solve for n.
(n*n) + (n*3) = 108
[tex]n^{2} +3n = 108[/tex] Now we move 108 to the other side by subtracting so we can factor.
[tex]n^{2} + 3n - 108 = 0[/tex]
(n )(n ) = 0
Find all the multiples of 108
1 x 108
2 x 54
3 x 36
4 x 27
6 x 18
9 x 12
Which one can we add or subtract together to get 3?
9 x 12 because 12 - 9 = 3
[tex]n^{2} + 3n - 108 = 0[/tex]
(n 12)(n 9) = 0 Now we figure out the signs. Since we have -108 one must be negative, and the 3 in the 2nd term (3n) is positive so:
(n + 12)(n - 9) = 0 Is our factored equation.
Our smallest number is 9, so n = 9
Our second number is n + 3 and 9 + 3 = 12
So our 2 integers are 9, 12, there sum would be 9 + 12 = 21

Answer:
131.25
Step-by-step explanation:

Given that,
Michael and four friends went trick-or-treating in his neighborhood they collected 525 pieces of candy if they split the candy evenly how many pieces of candy did each person get is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
here,
Total number of candies = 525
Total person = 5
Each of them get = 525 / 5 = 105
Thus, each of them would get 105 candies, as they are 5 in total.
