Answer to part C: organic oranges

---------------------------------------------------------------------
---------------------------------------------------------------------

Work Shown:

Part A
P(Organic|Oranges) = P(Organic AND oranges)/P(Oranges)
P(Organic|Oranges) = 0.19/0.30
P(Organic|Oranges) = 0.63

Part B
P(Non-organic|Oranges) = P(non-organic AND oranges)/P(oranges)
P(Non-organic|Oranges) = 0.11/0.30
P(Non-organic|Oranges) = 0.37

Part C
The probability in part A is larger compared to the answer in part B, so it's more likely to have someone pick organic oranges rather than non-organic oranges. Melina should restock organic oranges for the next sale.

A student took a test which had 6 questions. He would score 8 points on the test if all his answers are correct. If y represents the student's score when he got x questions incorrect, which graph best represents this situation?

Answers

m=(y2-y1)/(x2-x1) so if we take the endpoints (0,0) and (6,8)

m=(8-0)/(6-0)

m=8/6

m=4/3, and since we know we have the point (0,0) we know the line is just:

y=mx, using m found above...

y=4x/3

So the graph that will match this line is one that has a point on the origin and has a positive slope of 4/3. So another point other than the origin that will be quite clear is the point (3, 4)

Find the fifth roots of 243(cos 240° + i sin 240°)

Answers

The best way to find a root is to get the root of the coefficient, then divide the angle by what root you want for the first one, then add 360/root to get each additional angle until you have all the roots. So for the fifth root, get the fifth root of 243, then divide 240 by 5 for your first angle. You then write the root in the same form as the original, just with your new numbers. Now take 360/5 to find that you will add 72 to the angle to get your next angle. Keep adding 72 to get another angle until you have five roots in all.

Apply De Moivre's Theorem

zⁿ = rⁿ(cos.n.Ф + i.sinn.Ф).

The 5th root, that means that n = 1/5 ↔↔↔ rⁿ = r¹/₅ = ⁵√r

zⁿ = ⁵√(243) [cos (240+2kπ)/5 +i.sin(240+2kπ)/5]
with k = 1,2,3,..,n-1. Note that ⁵√(243) = 3

1st root : for k=0 → 3[cos(240/5)+isin(240/5) = 3(cos48°+isin48°)
2nd root : for k=1→3[cos(240+360)/5)+isin(240+360)/5]=3(cos120°+isin120°)

Suppose that 66% of people own dogs. if you pick two people at random, what is the probability that they both own a dog?

Answers

Final answer:

The probability of two people owning a dog when 66% of people own dogs is found by squaring the probability (0.66), giving us a result of 0.4356 or 43.56%.

Explanation:

The question asks to calculate the probability that both people picked at random own a dog when it is known that 66% of people own dogs. To find this probability, we can simply multiply the probability of the first person owning a dog by the probability of the second person owning a dog, assuming that these events are independent.

The probability that one person owns a dog is given as 66%, which is 0.66 in decimal form. Thus, the probability that both people own a dog is 0.66 × 0.66 (or 0.66 squared). Calculation yields:

0.66 × 0.66 = 0.4356

Therefore, the probability that both people own a dog is 0.4356, or 43.56%.

At the frozen yogurt shop, a machine fills cups with 4 ounces of frozen yogurt before adding the toppings. After the cups are filled, customers add as many toppings as they want without exceeding a total weight of 6 ounces. Which of the following represent the acceptable weights for the frozen yogurt options? Select all that apply:
A.) 0 < x ≤ 6
B.) 0 < x ≤ 3
C.) 4 ≤ x ≤ 6
D.) x ≤ 6
E.) |x - 5| ≤ 1
F.) |x - 2| ≤ 6

Answers

The yogurt can weigh above or equal to 4 ounces or less or equal to 6 ounces.

By writing an inequality and then converting it to an absolute value equation, we will see that the correct options are C and E.

How to find an inequality?

To find the inequality, we need to find the lower and upper bounds.

First, we know that the machine fills the cups with 4 oz of yogurt, so this is the minimum value allowed, we will have:

4 ≤ x

Then we can add toppings to a maximum value of 6 ounces, this will be the maximum, then we have:

4 ≤ x ≤ 6

We can also write this an absolute value equation, we define:

m = half of the difference of the bounds.M = lower bound + m

Then the absolute value equation is:

|x - M| ≤ m

By replacing what we found before, we have:

m = (6 - 4)/2 = 1M = 4 + 1 = 5

So the absolute value equation is:

|x - 5| ≤ 1

Finally, we can conclude that the correct options are C and E.

Mike and adam left a bus terminal at the same time and traveled in opposite directions. mike’s bus was in heavy traffic and had to travel 20 mi/h slower than adam’s bus. after 3 hours, their buses were 270 miles apart. how fast was each bus going?

Answers

adam's bus speed = a
mike's bus speed = m
total distace = t

m = a - 20

after 3 hour:

3 * (m + a) = t
3 * (m + a) = 270
3m + 3a = 270
[ 3 * (a - 20) ] + [ 3 * a ] = 270
[ 3a - 60 ] + 3a = 270
3a - 60 + 3a = 270
3a + 3a = 270 + 60
6a = 330

their speed:
a = 55
m = 55 - 20 = 35

There is a traffic light at the intersection of walnut street and Lawrence avenue. The traffic light in walnut street follows a cycle. It is green for 50 seconds, yellow for 10 seconds, and red for 30 seconds, as you travel along walnut and approach the intersection, what is the probability that the first color you see is red?

Answers

P(R)=30/(30+10+50)

P(R)=30/90

P(R)=1/3

Answer: The probability that the first color we see is red is 0.34.

Step-by-step explanation:

Since we have given that

Time taken by green color on the traffic light = 50 seconds

Time taken by yellow color on the traffic light = 10 seconds

Time taken by red color on the traffic light = 30 seconds

Total number of seconds = 50+10+30=90

So, Probability that the first color we see is red is given by

[tex]\dfrac{\text{Time alloted for red color}}{\text{Total number of seconds}}\\\\=\dfrac{30}{90}\\\\=\dfrac{1}{3}\\\\=0.3333...\\\\\approx 0.34[/tex]

Hence, the probability that the first color we see is red is 0.34.

A bridge in the shape of an arch connects two cities separated by a river. The two ends of the bridge are located at (–7, –13) and (7, –13), and the center of the arch on the bridge is located at (0, 0). Find the equation of the arch of the bridge.

Answers

The equation of the arch is y = (-13/49)x².

The equation of an arch can be described by a parabola when one side of the arch mirrors the other side. This is the case for the bridge problem given.

The center of the bridge is at the origin (0, 0), and it is the vertex of the parabola. Since the arch is symmetrical and the x-coordinate of the vertex is 0, the parabola is a vertical one. Thus, the equation will be in the form y = ax². To find the value of a, we will use the fact that one end of the bridge is at (7, -13).

Since (7, -13) is a point on the parabola, by plugging these values into the equation y = ax², we get:

-13 = a(7²)

-13 = 49a

a = -13/49

Thus, the equation is y = (-13/49)x².

A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is dilated with a scale factor of 1/5?

Answers

IF you are dilating about the origin, which you didn't exactly state, the new coordinates are A' (1/5, 1), B' (2/5, 1/5), C' (0, 4/5). Dilation is all about distance, so you have to move the new coordinates to whatever the scale factor is times the x and y distance. For example, A is at (1, 5), so 1/5 of 1 is 1/5, and 1/5 of 5 is 1, hence your new coordinate for A. It is a fifth of the distance from the origin as its preimage is.

Answers

Normally, the data path width for DIMMs is 64 bits but for the DIMMs that support ECC, the data path is 72 bits.

To add, error checking uses the extra 8 bits. ECC memory is more reliable than non-ECC memory but it costs more than a non-ECC memory. Comprising the DIMMS are a series of dynamic random-access memory integrated circuits. Mounted on a printed circuit board, these modules are designed for use in personal computers, workstations and servers.

The most common kinds of internal data corruption are detected and corrected by a type of computer data storage called error-correcting code memory.
