A produce store sold 63 red apples. If the ratio of red apples to green apples sold was 7: 2, what is the combined amount of red and green apples sold?
Answer:
81 apples
Step-by-step explanation:
7 divided by 2 = 3.5
63 divided by 3.5 = 18
63 red + 18 green = 81 total apples
Answer:
81
Step-by-step explanation:
If we just divide 63 by 7 we can understand the value of the units used in the ratio
63/7 = 9
So that means the value of one unit on the ratio is 9
2*9 = 18 = amount of red apples
63 + 18 = 81
Marcos raised $5,784 coordinating various fundraising activities throughout the year. He wants to divide this money evenly among 24 different charities. How much money should Marcos donate to each charity?
Answer:
$241 should be donated to each charity
Step-by-step explanation:
money donated to each charity = total raised ÷ number of charities
⇒ 5784 ÷ 24 = 241
Answer:
$241
Explanation:
[tex]\sf each \ charity = \frac{total \ money}{total \ number \ of \ charities}[/tex]
[tex]\sf each \ charity = \frac{5784}{24}[/tex]
[tex]\sf each \ charity =241[/tex]
$241 is distributes in each charity.
Phone calls arrive at the rate of 48 per hour at the reservation desk for regional airways.
A) Compute the probability of receiving three calls in a 10-minute interval of time?(to 4 decimals)
B) Compute the probability of receiving exactly 13 calls in 15 minutes. (To 4 decimals)
C) Suppose no calls are currently on hold. If an agent takes 10 minutes to complete the current call, how many callers do you expect to be waiting by that time?
D) What is the probability that none will be waiting?
E) If no calls are being processed, what is the probability that the agent can take 5 minutes for a personal time without being interrupted by a call?
The different probabilities and number of callers expected to be waiting are;
A) P(x = 3) = 0.0286
B) P(x = 13) = 0.1056
C) 8 will be waiting
D) P(x = 0) = 0.0003
E) P(x = 0) = 0.0067
How to find probability using Poisson distribution?
We are given the rate of 48 phone calls per hour.
Thus, we will use poisson's distribution formula;
P(x) = (λˣ × e^(-λ))/x!
A) Probability of receiving three calls in a 10-minute interval of time which is P(x = 3). Thus;
λ = 48 * (10/60)
λ = 8
P(x = 3) = (8³ × e⁻⁸)/3!
P(x = 3) = 0.0286
B) Probability of receiving exactly 13 calls in 15 minutes is P(x = 13). Thus;
λ = 48 * (15/60)
λ = 12
P(x = 13) = (12¹³ × e⁻¹²)/13!
P(x = 13) = 0.1056
C) No calls are currently on hold and it takes 10 minutes to complete one call. Thus;
λ = 48 * (10/60)
λ = 8
Thus, 8 will be waiting after 10 minutes.
D) Probability that no one will be waiting is;
P(x = 0) = (8⁰ × e⁻⁸)/0!
P(x = 0) = 0.0003
E) No calls being processed and it takes 5 minutes for a personal time without being interrupted by a call. Thus;
λ = 48 * (5/60)
λ = 4
P(x = 0) = (4⁰ × e⁻⁵)/0!
P(x = 0) = 0.0067

Answer:y-4 = -3/4(x-3)
Step-by-step explanation:
y-4 = -3/4(x-3)
y-4 = -3/4(x+3)
y = (-3/4)x - (9/4)+(4)
y = (-3/4)x - (9/4)+(16/4)
y = -3x/4 +7/4
Answer:
B: y= -2x+2
Step-by-step explanation:
General equation in slope intercept form:
y= mx+b , where m = slope, and b= y-intercept
For points (x1= 3, y1= -4) and (x2= 0, y2= 2)
m = ( y2-y1)/ (x2-x1) = (2- -4)/(0 -3) = 6/ -3 = -2
Choose one of the points that belong to the line and use it's coordinates
y = -2x + b , use point (x= 0, y= 2)
2 = -2*0 + b, 2= b
y= -2x+2

You're looking for the smallest number that's a multiple of both 30 and 40.
If you've learned about "Least Common Multiple" by now, you'll be happy
to know that that's exactly what this is, (because when you were learning it,
you wondered what in the world you could ever use it for). Well here you are.
The least common multiple of 30 and 40 is 120.
That's the 4th multiple of 30 and the 3rd multiple of 40.
If the trains are both in the station right now, then the next time they'll
both be here together will be 2 hours (120 minutes) from now.
And let me say in conclusion that when you ask for help with
a multiple-choice question, you must also post the choices that
you have. It's not fair to the helper if he doesn't know the choices

Answer:
No
Step-by-step explanation:
The inequality k ≥ 10 means "the variable, k, is equal to or more than 10." We are asked if 9 is a solution to the inequality.
The number, nine, is not a solution to this inequality, as 9 is not more than or equal to 10.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
No
Step-by-step explanation:
Hello.
The inequality pictured above (k≥10) means that any solution that is greater or equal to 10 fits it. Think of an alligator being the inequality symbol and wants what's bigger. Obviously if k is bigger the alligator wants that over a 10.
In this problem, when 9 is inputted to k, is it bigger or equal then ten?
It is not, which means it is NOT a solution.

352, 345, 338, ...
Find the 43rd term.
Answer:
Step-by-step explanation:
first term = a = 352
Common difference = d = second term - first term
= 345 - 352
= (-7)
nth term = a + (n-1)*d

Y -52 4 + 52 = 0 What is the solution to the system of equations?
Answer:
y = 156
Step-by-step explanation:
Solve for y:
y - 52 4 + 52 = 0
Multiply -52 and 4 together.
-52×4 = -208:
y + -208 + 52 = 0
Group like terms in y - 208 + 52.
Grouping like terms, y - 208 + 52 = y + (-208 + 52):
y + (-208 + 52) = 0
Evaluate 52 - 208.
52 - 208 = -156:
y + -156 = 0
Isolate terms with y to the left-hand side.
Add 156 to both sides:
y + (156 - 156) = 156
Hint: | Look for the difference of two identical terms.
156 - 156 = 0:
Answer: y = 156

How would you graph Y = -2X? Explain from beginning to end.
Step-by-step explanation:
Since there is no y-intercept, you start at the origin (0, 0)
The slope tells us that for every two units it goes down, it also goes one unit to the right
We know this because slope is rise/run (in this case -2/1) and the slope is negative, meaning that it starts higher up at the left and goes down towards the right.
To graph, start at (0, 0) and go down 2 units to get (0, -2) and then to the right one unit to get (1, -2)
That is the first point
Continue doing this
(1, -2) -> down 2 and to the right 1 -> (2, -4)
Alternatively, plug in values for x
y = -2(1) -> y=-2
When x=1, y=-2
And keep repeating until you get a good idea of what the line looks like
