In square QRST, points U and V are midpoints. If the square has a side length of 18 mm, what is the probability that a point chosen at random in the square lies in the shaded triangle region? Round the answer to the nearest thousandth. A. 0.028 B. 0.056 C. 0.125 D. 0.222
Answers
The formula for the area of triangle is b h / 2
Where:b = h = half of side length of square = 9 mm
Area of triangle = 9 mm * 9 mm / 2
Area of triangle = 40.5 mm^2
Area of square = s^2
Area of square = (18 mm)^2
Area of square = 324 mm^2
Probability that a point is in the shaded region
= Area of triangle / Area of square
= 40.5 / 324
= 0.125
The answer is letter C. 0.125

Class a has x students and class b has y students. the average of class a is 85 and class b is 90. when the scores of class a and b are combine the average is 88, what is the ratio of x to y
Answers
In similar manner, we are able to find for the total scores of the students from Class B. That would be, 90y.
Combining the scores, the new average then becomes 88. This is equal to,
(85x + 90y) / (x + y ) = 88
Cross-multiplying,
85x + 90y = 88x + 88y
Combine all the x's and y's in each side of the equation.
85x - 88x = 88y - 90y
Combining terms,
-3x = -2y
The ratio is obtained through the step below,
-3x/-3y = -2y/-3y
x/y = 2/3
Thus, the ratio is 2/3.

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.
What can you say about the nature of any other zeros of the quadratic equation which has one complex zero? Explain your answer.
Answers
[tex]x= \frac{-b+/- \sqrt{ b^{2}-4ac } }{2a} [/tex]
where a and b are coefficients of the variables and c is the constant in the quadratic equation. The nature of the roots could be real or complex. Real roots are those in whole numbers, fractions or decimals. Complex roots involve a term 'i' which is equal to √(-1). It stands for imaginary. You can get complex roots if the discriminant, the term with the square root in the quadratic formula, is negative. For example, if √(b^2-4ac) = √-50, that is imaginary which is equal to 50i. Also, notice that before the discriminant, there is a +/- sign. Therefore, if one of the complex roots is, say 6+50i, then the other root must be 6-50i.

If EF = HG and HG = 16, find the diameter of K
Answers
Answer:
Diameter of the circle K = 20 units
Step-by-step explanation:
Given that : EF = HG
Also, HG = 16 units
⇒ EF = 16 units
Now, any line drawn perpendicular to the chord always bisects the chord
⇒ KI will bisect the chord EF
⇒ EI = 8 units
Now, in ΔEIK using Pythagoras theorem we have :
⇒ EK² = 8² + 6²
⇒ EK² = 100
⇒ EK = 10 units
So, Radius of the circle K = 10 units
Now, Diameter of the circle K = 2 × 10
= 20 units
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
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 + mThen the absolute value equation is:
|x - M| ≤ m
By replacing what we found before, we have:
m = (6 - 4)/2 = 1M = 4 + 1 = 5So the absolute value equation is:
|x - 5| ≤ 1
Finally, we can conclude that the correct options are C and E.

If a seed is planted, it has a 90% chance of growing into a healthy plant. if 7 seeds are planted, what is the probability that exactly 4 don't grow?
Answers
Answer:
0.098415
Step-by-step explanation:
The way the question is worded is odd and you should probably actually include “don’t grow into a healthy plant” or something. You can use the binomial distribution. Suppose ∼Bin(6,0.1) so the probability that k trees don’t grow into a healthy plant is
Pr( = ) = (6 / ) 0.16^ 0.9^6−
Then the probability that two don’t grow into healthy plants is
Pr( = 2) = (6/2) 0.1^2 0.9^4
this is equal to 0.098415
To calculate the probability of exactly 4 out of 7 seeds failing to grow, use the binomial probability formula with n = 7, p = 0.10, and k = 4. The calculation involves combinations and exponentiation.
Explanation:The question is asking for the probability of exactly 4 seeds out of 7 failing to grow. Given that each seed has a 90% chance of growing into a healthy plant, which means each seed has a 10% (1 - 0.90) chance of not growing. To solve this, we can use the binomial probability formula: P(X = k) = C(n, k) * (pk) * ((1 - p)n - k), where n is the number of trials, p is the probability of success, and k is the exact number of successes. In this case, n = 7, p = 0.10 and k = 4. So, we get:
P(X = 4) = C(7, 4) * (0.104) * (0.907 - 4)
The calculation of this probability requires the use of combinations and exponentiation, providing the specific likelihood of having exactly 4 seeds out of 7 not growing into a healthy plant.

Determine whether the sequence converges or diverges. If it converges, give the limit. 60, 10, five divided by three, five divided by eighteen, ...
Answers
Using geometric sequence form, we can rewrite it as:
[tex]A_n = a_1 \cdot r^{n-1}[/tex]
[tex]A_n = 60 \cdot \frac{1}{6}^{n - 1}[/tex]
Since r < 1, there exists a limit, and thus, it is said to converge.
[tex]\lim_{n \to \infty} 60 \cdot (\frac{1}{6})^{n - 1}[/tex]
[tex] = 0[/tex]
Since the ratio is still positive, as n tends towards infinity, the graph of the sequence will never go below the horizontal. Thus, we say that the limit of the function is zero, which means that as we increase the size of n, eventually after the infinite-th time, it will hit zero.
A committee consisting of 6 people is to be selected from eight parents and four teachers. find the probability of selecting three parents and three teachers.

Answers
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.

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.

Answers
To rank the company sales by smallest to largest percent of increase, calculate the percent of increase for each company, which in this case is 0% for all companies.
Explanation:To rank the company sales by smallest to largest percent of increase, we need to calculate the percent of increase for each company. The percent of increase can be found by subtracting the initial value from the final value, dividing that number by the initial value, and then multiplying by 100.
For company A: Percent of increase = ((170(1.04)x - 170(1.04)x) / (170(1.04)x)) * 100 = 0%For company B: Percent of increase = ((330(1.80)x - 330(1.80)x) / (330(1.80)x)) * 100 = 0%For company C: Percent of increase = ((250(0.06)x - 250(0.06)x) / (250(0.06)x)) * 100 = 0%For company D: Percent of increase = ((120(1.09)x - 120(1.09)x) / (120(1.09)x)) * 100 = 0%Since all the percent of increase values are 0%, the company sales can be ranked in any order, as there is no change in sales for any of the companies.

Hosting a breakfast for 25 people you plan to serve scrambled eggs the grocery store sells eggs in cartons and each carton can feed people. how many cartoons of eggs must you buy to ensure each guest a serving
Answers
The number of egg cartons required to serve 25 people with scrambled eggs is 3 cartons, assuming each carton serves 12 people and we cannot purchase partial cartons.
To calculate the number of egg cartons needed to serve scrambled eggs to 25 people, we first need to know how many people each carton can serve. However, it appears there's a typo or missing information in the question regarding the number of people an egg carton can serve. Assuming that one egg carton can serve a certain number of people, we'd use that information to determine the total number of cartons required.
If we refer to the related information provided about pancakes - where one egg is needed for 8 pancakes - we can draw a parallel for eggs for scrambled eggs. If one egg serves one person in the case of scrambled eggs, and typically there are 12 eggs in a carton, then one carton would serve 12 people.
Using this assumption, since we have 25 people to serve, we can calculate the number of cartons needed as follows:
25 people
Since we cannot purchase a partial carton, we would need to round up to the nearest whole number. Therefore, we would need to purchase 3 cartons of eggs to ensure each guest has a serving.
