Suppose you buy 6 buckets of apples and 4 buckets of peaches for $42. If
you bought 8 buckets of apples and 2 buckets of peaches, you would have
spent $36. How much is one bucket of apples (a), and one bucket of peaches
(p)?
A. a = $3, p = $6
B. a = $8, p = $2
C. a = $6, p = $4
D. a = $6, p = $3
SUBMIT
Answers
Answer:
A. a = $3, p = $6
Step-by-step explanation:
Let the cost of a bucket of apple=a
Let the cost of a bucket of peaches=p
6 buckets of apples and 4 buckets of peaches costs $42.
6a+4p=428 buckets of apples and 2 buckets of peaches costs $36.
8a+2p=36 (Multiply by 2 to make the coefficient of p 4)16a+4p=72We solve the two resulting equations simultaneously
6a+4p=42
16a+4p=72
Subtract
-10a=-30
Divide both sides by -10
a=$3
Next, we substitute a=$3 in any of the equation to solve for p
6a+4p=42
6(3)+4p=42
4p=42-6(3)
4p=42-18
4p=24
Divide both sides by 4
p=$6
Therefore, a bucket of apple costs $3 and a bucket of peaches costs $6.
A car is traveling 80 KM in an hour how many minutes will it take to go from Miami to key largo
Answers
84.5 minutes reeeeeee
The car will take 84 minutes to go from Miami to Key Largo.
Given that, speed=80 km/hour and distance = 70 miles.
What is the speed of a object?Speed is the rate at which an object's position changes, measured in meters per second. The equation for speed is simple: distance divided by time.
Now, convert miles to kilometres. We know that 1 mile=1.6 kilometre.
That is 70 miles =70×1.6 =112 km
Then, Time=Distance/Speed
⇒Time =112/80=1.4 hours
So, 1.4 hours=60×1.4=84 minutes
Therefore, the car will take 84 minutes to go from Miami to Key Largo.

Based on that sample statistic, what is the best estimate of the proportion for all eligible voters in the town? Round to two decimal places as needed.
Answers
Answer:
The best estimate of the proportion for all eligible voters in the town, that is, the best estimate for the population, is 0.47.
Step-by-step explanation:
Since the sample is large enough, the proportion from the sample is the best estimate for the proportion of the population.
In this question, we have that:
For the sample, the proportion who say that they plan to vote in the next mayoral election is 0.47
So the best estimate of the proportion for all eligible voters in the town, that is, the best estimate for the population, is 0.47.
A student walk 60m on a bearing of 028 degree and then 180m due east. How is she from her starting point, correct to the nearest whole number?
Answers
Answer:
She is 215 m from the starting point
Step-by-step explanation:
Let's begin by constructing a figurative representation of the information given (figure attached)
We know 2 sides of the triangle and the inner angle, we can therefore use the Cosine Rule
Mathematically represented as:
b² = a² + c² - 2ac(CosB)
b = ?, a = 60 m, c = 180, B = 118° (the sum of the 90° right angle at B + the interior angle of 28° from A)
b² = 60² + 180² - 2(60)(180)Cos 118°
b² = 3600 + 32400 - (- 10140.586)
b² = 46140.586 ⇒ b = [tex]\sqrt{46140.586}[/tex]
b = 214.8 m ≈ 215 m
b = 215 m (to the nearest whole number)
∴ the student is 215 m from the starting point
A loan company charges $30 interest
for a one month loan of $500. Find the annual interest they are charging
Answers
Answer:
0.72%
Step-by-step explanation:
Finding what percentage is $30 of $500:
30/500 x 100 = 6
So, it is 5% per month.
Converting it to annual:
6% x 12 = 0.72%
The annual interest they are charging is $360.
What is interest?Interest is the price you pay to borrow money or the cost you charge to lend money.
Now it is given that,
Amount of interest charged = $30
Amount of loan = $500
Duration = 1 month
Now since 1 year = 12 month
Thus, Amount of interest charged in 1 year = 12 * $30
⇒ Amount of interest charged in 1 year = $360
this is the amount they are charging annually.
Thus, the annual interest they are charging is $360.

Let's derive the equations for the two graphs;
For the graph towards the right,
The slope = y2-y1/x2-x1; so we choose two corresponding points (x1,y1); (x2,y2)
Let's choose points;
(2,1) and (3,2)
The slope = 2-1/ 3-2 = 1/1 = 1
From the general equation of a line
y = mx + c = 1× x + (-1) = x-1
y = x-1
Similarly for that towards the left we have;
The slope = y2-y1/x2-x1; so we choose two corresponding points (x1,y1); (x2,y2)
Let's choose points;
(2,1) and (3,2)
The slope = 2-1/ 3-2 = 1/1 = 1
From the general equation of a line
y = mx + c = 1× x + (-1) = x-1
y = x-1
Similarly for that towards the left we have;
The slope = y2-y1/x2-x1; so we choose two corresponding points (x1,y1); (x2,y2)
Let's choose points;
(-7,0) and (-4,-3)
Slope = -3-0/ -4-(-7) = -3/ 3 = -1
From the general equation of a line
y = mx + c = -1× x + c = -x + c
Since c is not obvious we can find the equation by picking just a point along the graph along side an arbitrary (x,y) point hence we have for slope;
If we pick (-7,0)
y-0 / x-(-7) = -1
y / x+7 = -1
y = -x -7
The equations of the graphed lines are;
y=x-1
y=-x-7
Look at option D you we see it's the same as the equation of the graph towards the right y=x-1

Question:
The temperatures at several times of the day are shown in the coordinate plane below. The x-axis represents the number of hours before or afternoon. For example, -1 would represent 11 a.m. The y-axis represents the temperature in degrees Celsius.At 5 p.m, the temperature is halfway between the temperature at 2 p.m. and the temperature at 8 p.m.
What coordinates represent the temperature at 5 p.m.?
Answer:
(5, 2)
=> At 5pm, the temperature is at 2⁰C
Step-by-step Explanation:
Coordinates of any point on a cartesian/coordinate plane is represented by (x, y). Where x is the number at the point on z-axis, while y is the number at the same point on the y-axis.
From the diagram of the coordinate plane attached below, we can simply find out what coordinates represent the temperature at 5pm.
==> Given that the temperature at 5pm is half way between the temperature at 2pm (y=7) and temperature at 8pm (y=-3), the point that is being referred to = [7+(-3)] ÷ 2 = ⁴/2 = 2 (i.e. 2 on the y axis representing temperature)
*The position of the point is indicated in the second picture that is attached below.
At that position of the point, we have 2 as the coordinate for the y axis representing temperature, and at that same position, we have 5 on the x-axis representing the number of hours.
Therefore, coordinates of the point (x, y) representing 5p.m = (5, 2)

uppose that Mary's utility function is U(W) = W0.5, where W is wealth. She has an initial wealth of $100. How much of a risk premium would she want to participate in a gamble that has a 50% probability of raising her wealth to $115 and a 50% probability of lowering her wealth to $77? Mary's risk premium is $ nothing. (round your answer to two decimal places)
Answers
Note that [tex]U(W) = W^{0.5}[/tex]
Answer:
Mary's risk premium is $0.9375
Step-by-step explanation:
Mary's utility function, [tex]U(W) = W^{0.5}[/tex]
Mary's initial wealth = $100
The gamble has a 50% probability of raising her wealth to $115 and a 50% probability of lowering it to $77
Expected wealth of Mary, [tex]E_w[/tex]
[tex]E_{w}[/tex] = (0.5 * $115) + (0.5 * $77)
[tex]E_{w}[/tex] = 57.5 + 38.5
[tex]E_{w}[/tex] = $96
The expected value of Mary's wealth is $96
Calculate the expected utility (EU) of Mary:-
[tex]E_u = [0.5 * U(115)] + [0.5 * U(77)]\\E_u = [0.5 * 115^{0.5}] + [0.5 * 77^{0.5}]\\E_u = 5.36 + 4.39\\E_u = \$ 9.75[/tex]
The expected utility of Mary is $9.75
Mary will be willing to pay an amount P as risk premium to avoid taking the risk, where
U(EW - P) is equal to Mary's expected utility from the risky gamble.
U(EW - P) = EU
U(94 - P) = 9.63
Square root (94 - P) = 9.63
If Mary's risk premium is P, the expected utility will be given by the formula:
[tex]E_{u} = U(E_{w} - P)\\E_{u} = U(96 - P)\\E_u = (96 - P)^{0.5}\\(E_u)^2 = 96 - P\\ 9.75^2 = 96 - P\\95.0625 = 96 - P\\P = 96 - 95.0625\\P = 0.9375[/tex]
Mary's risk premium is $0.9375

n a survey of 331 customers, 66 say that service is poor. You select two customers without replacement to get more information on their satisfaction. What is the probability that both say service is poor?
Answers
Answer:
3.93% probability that both say service is poor
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The customers are chosen without replacement, and the order in which they are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
What is the probability that both say service is poor?
Desired outcomes:
Two saying it is poor, from a set of 66. So
[tex]D = C_{66,2} = \frac{66!}{2!(66-2)!} = 2145[/tex]
Total outcomes:
Two customers from a set of 331. So
[tex]T = C_{331,2} = \frac{331!}{2!(331-2)!} = 54615[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{2145}{54615} = 0.0393[/tex]
3.93% probability that both say service is poor

Consider groups of 17 trucks and let X be the number of trucks in a group that have passed the inspection. What is the probability that at least 10 but fewer than 13 trucks pass the inspection
Answers
Answer:
0.2308 = 23.08% probability that at least 10 but fewer than 13 trucks pass the inspection
Step-by-step explanation:
For each truck, there are only two possible outcomes. Either they pass the inspection, or they do not. The probability of a truck passing the inspection is independent of other trucks. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
80% of all trucks undergoing a brake inspection at a certain inspection facility pass the inspection.
This means that [tex]p = 0.8[/tex]
17 trucks:
This means that [tex]n = 17[/tex]
What is the probability that at least 10 but fewer than 13 trucks pass the inspection
