In the laundry basket there are 4 black socks, 7 pink socks, and 10 white socks. Allison will randomly select 2 socks from the basket one at a time without replacement. What is the probability that Allison will select 2 pink socks?
Answer: [tex]\dfrac{1}{10}[/tex]
Step-by-step explanation:
Given: In basket, we have
4 black socks, 7 pink socks, and 10 white socks.
Total socks = 4+7+10 = 21
Probability that first sock is pink = [tex]\dfrac{\text{Number of pinks socks}}{\text{Total}}=\dfrac{7}{21}=\dfrac13[/tex]
Now basket has 6 pink socks left and total socks left= 20
Probability that second sock is pink =[tex]\dfrac{6}{20}=\dfrac{3}{10}[/tex]
The probability that Allison will select 2 pink socks = [tex]\dfrac13\times\dfrac{3}{10}=\dfrac{1}{10}[/tex]
Hence, the probability that Allison will select 2 pink socks = [tex]\dfrac{1}{10}[/tex]
The zurn family ate at a restaurant that was having 15% discount on that day .Their meal costs 64.75,and they left a 20% tip .What is the total cost of the meal
Answer:
[tex]66.05[/tex]
Step-by-step explanation:
Cost of meal = [tex]64.75[/tex]
Cost of meal after discount of [tex]15\%[/tex]
[tex]64.75-64.75\times 0.15[/tex]
[tex]=64.75(1-0.15)[/tex]
[tex]=55.0375[/tex]
Cost of the meal after tip of [tex]20\%[/tex]
[tex]55.0375\times (1+0.2)[/tex]
[tex]=66.045\approx 66.05[/tex]
The total cost of the meal was [tex]66.05[/tex].

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.
x = ±3
x = 3
x = -3
x = ±9
2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.
h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)
Answer:
Part 1)
A
Part 2)
C
Step-by-step explanation:
1)
We are given:
[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]
And that:
[tex]h(x)=f(x)/g(x)[/tex]
And we want to now for which values of x is h(x) undefined.
So, by substitution:
[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]
Remember that for rational functions, the function will be undefined if and only if the denominator is 0.
This is because we cannot divide by 0.
So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:
[tex]x^2-9=0[/tex]
Add 9 to both sides:
[tex]x^2=9[/tex]
Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:
[tex]x=\pm 3[/tex]
So, h(x) is undefined for ±3.
Our answer is A.
2)
We are given:
[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]
And we want to find:
[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]
So:
[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]
Distribute:
[tex]h(x)=3^x-3^{2x}+3^x[/tex]
Combine like terms:
[tex]h(x)=2(3^x)-3^{2x}[/tex]
Rewrite:
[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]
Factor out:
[tex]h(x)=3^x(2-3^x)[/tex]
So, our answer is C.

If the national average for a gallon of gas is $3.10, how much should you expect to pay for gas in philadelphia versus atlanta
Answer: $3.63 / $3.29
Step-by-step explanation:
In Philadelphia, you would pay:
= 3.10 * Percentage of national average for transport
= 3.10 * 117%
= $3.63
In Atlanta:
= 3.10 * Percentage of national average for transport
= 3.10 * 106%
= $3.29
The table below compares the cost of living in Philadelphia and Cleveland, with the numbers representing percentages of the national average.

3 A small photograph has a width of 4 cm and a length of 6 cm
Dean enlarges the small photograph
The enlarged photograph has a length of 21 cm
Work out the width of the enlarged photograph
Answer:
14 cm
Step-by-step explanation:
Given that the width is 4 cm and the length is 6cm. If after enlargement, the length becomes 21 cm, the multiplier or factor of enlargement x may be computed as
6 * x = 21
Divide both sides by 6
x = 21/6
= 7/2 = 3.5
Hence increasing the width by the same factor, the width of the enlarged photograph will be
= 3.5 * 4 cm
= 14 cm

A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?
Answer:monthly rent of a 1-bedroom apartment= $280
Step-by-step explanation:
Let the cost of 1 bed room apartment = x
And the cost of two bedroom apartment= 2x-40
Since the cost of of two bedroom apartment = $520
Then the cost of one bed room part will be expressed as
520= 2x- 40
520+40 = 2x
560= 2x
x= 560/ 2
x= 280
Therefore the cost of 1 bed room apartment = x= $280

Last year Sandy earned
$1,978 per month. If she
worked for 11 months,
about how much did Sandy
earn last year?
Salary earned by Sandy last year = $21758.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
Salary of Sandy per month = $1978
Salary earned by Sandy in 11 months = 11 × $1978
= $21758
Hence, $21758 is the salary earned by Sandy last year.

kilogram?
Answer: $3.60
Step-by-step explanation:
If you need 4.8 kilograms of potatoes and each kilograms costs $0.75, then we should multiply 0.75 by 4.8 to find the cost of 4.8 kilograms of potatoes.
4.8 x 0.75 = 3.6.
Therefore, the cost of 4.8 kilograms is $3.60 dollars. I hope this helps, and good luck!

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?
Answer:
[tex]\boxed {\boxed {\sf \$54.80}}[/tex]
Step-by-step explanation:
Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.
[tex]commission= commission \ rate * sales[/tex]
His rate is 4% and his sales are $1,370
[tex]commission= 4\% * \$1370[/tex]
Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.
4/100= 0.04 4.0 --> 0.4 --> 0.04[tex]commission= 0.04* $1370[/tex]
[tex]commission = \$ 54.8[/tex]
Chris's commission is $54.80
Question 3. Find the distance between P(4,5) and the line with equation 8x + 5y = 20
Answer:
Step-by-step explanation:
8x+5y = 20
y = (-8/5)x + 4
slope of the line is -8/5.
slope of any perpendicular to the line is ⅝.
line of slope ⅝ that passes through P(4,5):
y-5 = ⅝(x-4)
y = ⅝x + 2.5
find intersection of lines
⅝x + 2.5 = (-8/5)x + 4
25x + 100 = -64x + 160
89x = 60
x = 60/89, y = 260/89
distance between (60/89, 260/89) and (4,5) = 3.92
