A jewelry box contains 13 gold earrings, 10 silver earrings and 12 titanium
earrings. Two earrings are drawn at random with replacement. Find the
probability that they are made of different materials.
Answer:
The probability is 406/625
Step-by-step explanation:
If they are of different materials, we have the following combinations of selection;
(gold and silver) or ( silver and titanium) or (gold and titanium )
The number of earrings present is 13 + 10 + 12 = 25
Probability of selecting a gold earring is 13/25
Probability of a silver is 10/25
Probability of a titanium is 12/25
Substituting these into the probabilities, we have;
(13/25 * 10/25) + (10/25 * 12/25) + (13/25 * 12/25)
= 130/625 + 120/625 + 156/625 = 406/625

What is the equation of the line that passes through the point (-5,-6) and has a slope of 3/5?
Answer:
y=3/5x-3
Step-by-step explanation:
First, put the slope in point-slope form: y-y1=x(x-x1)
y+6=3/5(x+5)
Distribute 3/5 to (x+5) and simplify.
y+6=3/5x+3
y=3/5x-3

Answer:
0.20m + 650 < 755
Step-by-step explanation:
So you know that m is the total amount of miles that he travelled, so the cost of these miles would have been 0.20m. The total also included 650 and it has to be less than 755. Thus the equation would be 0.20m + 650 < 755 which means that the sum of 0.20m (cost of miles) and 650 (night cost) is less than (< means less than something else on the right) 755.

Answer:
Y = 130
X = 20
Z = 110
Answer:
y= 130 degrees x= 20 degrees z= 110 degrees
Step-by-step explanation:
I solved top left triangle first. So, we know all triangles add up to 180 degrees and we have two on the angles so 85 + 45 = 130 then 180 - 130 = 50 so the missing angle near y is 50. Now to figure out Y then you just subract your answer (50) from 180 which you get 130. So y is 130 degrees. Then to figure out X, you just do 180 - 130 = 50, 50 - 30 = 20, so x is equal to 20 degrees. Then lastly to figure out z we know that the missing angle is 50 because its vertical to the other 50 degree so now you do 180 - 20 = 160, 160 - 50 = 110 degrees.

The area of a rectangular painting is 8428 cm² If the width of the painting is 86 cm, what is its length?
9514 1404 393
Answer:
98 cm
Step-by-step explanation:
Area is the product of length and width. Fill in the given numbers in the formula and solve for length:
A = LW
8428 cm² = (86 cm)L
L = 8428 cm²/(86 cm) = 98 cm . . . . . divide both sides by 86 cm
The length of the painting is 98 cm.
Given the functions f(x)=6x-3 and h(x)=10x+5, find the value of x for which f(x)=h(x)
Answer:
The functions equal each other when x=-2.
Step-by-step explanation:
Setting the functions equal to each other gives you:
6x-3=10x+5.
Consolidating the variables and constants, you get:
4x=-8.
Solving for x gives you:
x=-2.

r = 3
Area = π x 3²
= π x 9
= 28.27 in²
which of the following is an irrational number?
Answer:
B
Step-by-step explanation:
The other choices are terminal numbers which makes them rational numbers but square root of 19 is an irrational number because square root of 19 is 4.3588989.... This makes it an irrational number since it's just random numbers after the decimal point.
A bakery sells bagels at two different rates. When a customer buys fewer than 12 bagels, each one costs $1.25. When a customer buys 12 or more bagels, the first 12 bagels cost $1 each and each additional bagel costs $0.75.
Which TWO inequalities and constraints below represent the price for b bagels??
Question 1 options:
1.25b when b 12
1b when b < 12, then 0.75b
1b when b ≤ 12, then 0.75b
0.75b for b < 12, then 1b
0.75b for b ≤ 12, then 0.75b
Answer:
1.25b when b < 12 , 1b & then 0.75 b when b > 12
Step-by-step explanation:
Price for b bagels = Price x Quantity* Less than 12 bagels bought, cost $1.25 per bagel
So, price for b bagels, when (b < 12) = 1.25b
* 12 or more than 12 bagels bought, cost $1 upto first 12 bagels & 0.75b on each additional bagel
So, price for b bagels, when (b = 12) = b
So, price for b bagels, when (b > 12) = b + 0.75b' , where b' denotes extra b beyond 12
The inequality used to represent this constraints is:
Price = 1.25b when b < 12
Price = 0.75b + 3 when b ≥ 12
Inequalities is an expression used to show the non equal comparison of numbers and variables.
Let b represent the number of bagels bought.
When a customer buys fewer than 12 bagels, each one costs $1.25. Hence:
Price = 1.25b when b < 12
When a customer buys 12 or more bagels, the first 12 bagels cost $1 each and each additional bagel costs $0.75. Hence:
Price = 12 + (b - 12)0.75 = 0.75b + 3 when b ≥ 12
The inequality used to represent this constraints is:
Price = 1.25b when b < 12
Price = 0.75b + 3 when b ≥ 12

simplify 4+3x=22
Step by step explanation
Answer:
x = 6
Step-by-step explanation:
Rearrange terms
4 + 3 = 2 2
3 + 4 = 2 2
Subtract 4 from both sides of the equation
3x+4=22
3 + 4 − 4 = 2 2 − 4
Simplify (Subtract the numbers )
3 = 1 8
Divide both sides of the equation by the same term
3 = 1 8
3 / 3 = 1 8 /3
Simplify (Cancel terms that are in both the numerator and denominator

What is the exact distance from (-5,1) to (3,0).
Answer:
The distance between the two points is [tex]\sqrt{65} \ \text{units}.[/tex]
Step-by-step explanation:
In order to find the distance between two coordinate pairs, we can use the distance formula:
[tex]\displaystyle \bullet \ \ \ d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Our coordinate pairs need to be labeled accordingly, so we can use this naming system:
[tex]\bullet \ \ \ (x_1, y_1), (x_2, y_2)[/tex]
This assigns a name to our points:
[tex]x_1 = -5[/tex][tex]y_1 = 1[/tex][tex]x_2 = 3[/tex][tex]y_2 = 0[/tex]Therefore, we can plug these into the formula and solve:
[tex]d=\sqrt{(3-(-5))^2+(0-1)^2}\\\\d=\sqrt{(8)^2+(-1)^2}\\\\d=\sqrt{8^2+1^2}\\\\d=\sqrt{64+1}\\\\d=\sqrt{65}[/tex]
Therefore, the distance between the two points is [tex]\sqrt{65} \ \text{units}[/tex].

A manager in a call center needs to determine how many agents to schedule next week.
Based on previous data, she expects to get 7,940 calls next week. The following conditions
apply:
• On average, call center agents can handle seven calls an hour.
• The call center is open for 10 hours, 5 days a week.
Full-time agents work 40 hours per week, but are only on calls for 35 hours a week.
Part-time agents work 20 hours a week, but are only on calls 17 hours per week.
Answer:
Number of calls expected in next week by manager = 7940
Average Number of calls that call center agent will attend in an hour =7 calls
It is also given that, Call center remain open for 10 hours 5 days a week.
Also, it is given that, full time agents work 40 hours a week but are only on call for 35 hours per week ,Part time agents work 20 hours a week but are only on calls 17 hours per week .
⇒Number of hours worked by full time agents × Number of calls attended in an hour × Number of full time agents + Number of hours worked by Part time agents × Number of calls attended in an hour × Number of Part time agents ≤ 7940
⇒35 × 7×Number of full time agents +17 × 7 ×Number of Part time agents ≤ 7940
Option A
⇒35×15×7+17×7×15
= 3675+1785
= 5460
Option B
⇒35 ×7×20+17×7×7
=4900 +833

Option E
⇒28×35×7+17×7×10

Option E, ⇒ 28 full time agents and 10 part time agents , is best to meet the scheduling needs is most appropriate, that is nearer to 7940 calls.
f(0) =4 and f(2)=8 slope intercept form of the equation of the line
Answer:
y=2x+4 or f(x)=2x+4
Step-by-step explanation:
f(0)=4 is (0,4) and f(2)=8 is (2,8)
first, find the slope using the equation y2-y1/x2-x1
8-4/2-0
4/2
2
now, take one of the points, and put it into the equation y2-y1=m(x-x1) (m is slope)
take (0,4) for example
y-4=2(x-0)
y-4=2x
y=2x+4
y=f(x)
so, substitute as
f(x)=2x+4
hope this helps!
