150
275
325
A reasonable prediction for the number of times the event of landing on an even number will occur in 550 rolls is 275.
When rolling a fair 6-sided die, there are three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5). Therefore, the probability of rolling an even number is 3/6 or 1/2.
To predict the number of times the event of landing on an even number will occur in 550 rolls, we can multiply the probability of rolling an even number by the total number of rolls:
Expected number of even rolls = Probability of rolling an even number x Total number of rolls
Expected number of even rolls = (1/2) x 550
Expected number of even rolls = 275
Therefore, a reasonable prediction for the number of times the event of landing on an even number will occur in 550 rolls is 275.

The missing angle C of the given triangle using law of cosine is: 62.1°
How to use law of cosine?The Law of Cosines is defined as a numerical formula that relates the side lengths and points of any triangle. It expresses that the square of any side of a triangle is equivalent to the number of squares of the other different sides short two times the result of those sides and the cosine of the point between them.
Numerically, the Law of Cosines can be communicated as:
c² = a² + b² - 2abcos(C),
where c is the length of the side inverse to the point C, and an and b are the lengths of the other different sides.
Thus:
90² = 55² + 50² - 2(55 * 50)cos(C),
2575 = 5500 cos C
2575/5500 = cos C
cos C = 0.4682
C = cos⁻¹0.4682
C = 62.1°

Please teach me reason. Thank you for help :)
Based on the pattern, the missing section in the middle row is:
9282
The sequence seems to move in a clockwise or counter-clockwise fashion, filling in the digits. Some observations:
• The first and last rows are mirror images of each other, just reversed. So the middle section should continue that pattern.
• Going clockwise, 2 comes before 8. So 9282 fits.
• The digits in each section increase (or decrease) by 1 each time, except for the overlaps at the corners. So 9282 maintains that incremental pattern.
• The total sum of each row is the same: 391283, 9282? 1??391, 219382, 839128, 382193. Filling in 9282 for the middle section keeps the same overall sum.
• No other combination of 2 digits in that range (92-99 or 20-29) fits the pattern on both sides of the missing section. 9282 is the only logical choice.
So with all these clues pointing to 9282, that is the number that belongs in the missing section of the middle row. Let me know if any additional explanation is needed! I can also re-layout the pattern with the missing section filled in if that would be helpful.

In a right triangle, the length of one leg is 6 units. The length of the other leg is 8 units. What is the length of the hypotenuse?
Answer:
Step-by-step explanation:
Using the Pythagorean Theorem, we can find the length of the hypotenuse.
a² + b² = c²
6² + 8² = c²
36 + 64 = c²
100 = c²
√100 = c
10 = c
Answer: 10 units
Step-by-step explanation:
To find the hypotenuse of a triangle, use the Pythagorean Theorem (A² + B² = C²).
In this equation, A is 6, B is 8, and C is x, or the hypotenuse.
1. 6² + 8² = x²
2. 36 + 64 = x²
3. 100 = x²

find the surface area of the right prism.
8 ft
2 ft
3 ft
Answer: 92 ft²
Step-by-step explanation:
To find the surface area of a right prism, we will find the area of each side and add them together. We have three sets of two congruent sides. We will write an equation representing the area of these sides, set it equal to the surface area, and solve by simplifying.
2(8 ft * 3 ft) + 2(3 ft * 2 ft) + 2(8 ft * 2 ft) = Surface Area
2(24 ft²) + 2(6 ft²) + 2(16 ft²) = Surface Area
48 ft² + 12 ft² + 32 ft² = Surface Area
92 ft² = Surface Area

1.282 1.645 1.960 2.326 2.576
The percentage with a 95% confidence interval that has an error bound of at most 3%.
What is percentage?
Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the symbol "%". For example, if there are 20 red marbles out of 100 marbles in a jar, we can say that the percentage of red marbles is 20%. Similarly, if a store offers a 10% discount on a $50 item, the discounted price would be $45.
Percentages are commonly used to represent proportions or rates in various contexts, such as finance, and science. They allow us to easily compare and communicate numbers on a standardized scale, making it easier to interpret and analyze data.
To estimate the required sample size, we need to use the following formula:
n = (z*σ / E)^2
where:
n is the sample size we need to estimate the percentage with the desired error bound
z is the z-score for the desired level of confidence (95% in this case), which is 1.96
σ is the standard deviation of the population (unknown)
E is the desired margin of error, which is 3% of the percentage we are trying to estimate
Since we do not know the standard deviation of the population, we can use a conservative estimate of 0.5 (which gives the largest possible sample size).
Substituting the values we have:
n = (1.96 * 0.5 / 0.03)^2
n = 1067.11
So we would need to poll at least 1068 students to estimate the percentage with a 95% confidence interval that has an error bound of at most 3%.

Answer:
We can use a Venn diagram to visualize the information given in the problem.
Let M, B, and C represent the sets of students who pass mathematics, biology, and chemistry, respectively. We are given the following information:
|M| = 10 (the number of students who pass mathematics)
|B| = 30 (the number of students who pass biology)
|C| = 25 (the number of students who pass chemistry)
|M ∩ B| = 11 (the number of students who pass both mathematics and biology)
|B ∩ C| = 10 (the number of students who pass both biology and chemistry)
|M ∩ C| = 7 (the number of students who pass both mathematics and chemistry)
|M ∩ B ∩ C| = ? (the number of students who pass all three subjects)
We know that:
| M ∪ B ∪ C | = |M| + |B| + |C| - |M ∩ B| - |B ∩ C| - |M ∩ C| + |M ∩ B ∩ C|
Substituting the given values:
| M ∪ B ∪ C | = 10 + 30 + 25 - 11 - 10 - 7 + |M ∩ B ∩ C|
Simplifying:
| M ∪ B ∪ C | = 37 + |M ∩ B ∩ C|
We also know that:

Mary is babysitting a 4-year-old. The little boy wants to play in the kiddie pool in the backyard. Mary knows that using the hose that is near the kiddie pool will take 30 minutes to fill up. The little boy has already asked 17 times if the pool is ready but she hasn't even turned on the water yet. Mary also knows that the hose from the front yard works faster and can fill the pool in 1/2 the time as the hose in the back yard. If she can use both hoses at the same time, how long will it take for the pool to fill up?
(PLEASE SHOW YOUR WORK)(I saw other people get 7.5 min and 75 min but those answers are incorrect.)
A. 5 minutes
B. 10 minutes
C. 22.5 minutes
Using both hoses will take 10 minutes to fill up the kiddie pool. Mary can fill up 1/3 of the pool using the front yard hose in 10 minutes and 1/6 of the pool using the backyard hose in 10 minutes.
To solve this problem, we need to use the concept of rates. Let's assume the rate of the hose in the backyard is x, so the rate of the hose in the front yard is 2x (because it is twice as fast as the other hose).
The combined rate of the two hoses is x + 2x = 3x, which means they can fill the pool in 30/3x = 10/x minutes.
We know that the area of the pool is 600 square feet and each small rock covers 20 square feet, so we need a total of 600/20 = 30 small rocks to cover the pool.
Since the mass of each rock is 20 grams, the total mass of all 30 rocks is 30 x 20 = 600 grams.
To find the density, we divide the total mass (600 grams) by the total volume of the rocks (30 x 20 cubic feet = 600 cubic feet)
Density = 600g / 600 cubic feet = 1g/cubic foot
Therefore, the answer is B. 10 minutes for the pool to fill up, and the density of the rocks is 1 gram per cubic foot.

A funnel has a diameter of 9 in. and is 16 in. deep. What is the volume of the funnel to the nearest tenth of a unit?
The volume of the funnel to the nearest tenth of a unit is approximately 341.4 cubic inches.
What is volume?
Volume is a measure of the amount of space that a three-dimensional object occupies. It is the quantity of space that is enclosed within a closed surface, and is typically measured in cubic units, such as cubic meters ([tex]m^3[/tex]), cubic centimeters ([tex]cm^3[/tex]), cubic feet ([tex]ft^3[/tex]), or gallons (gal).
We can use the formula for the volume of a cone to find the volume of the funnel, since a funnel is essentially a cone with a hole at the top. The formula for the volume of a cone is:
[tex]V = (1/3)\pi r^2h[/tex]
where V is the volume, r is the radius of the circular base, and h is the height of the cone.
Since the funnel has a diameter of 9 inches, its radius is half of that, or 4.5 inches. The height of the funnel is given as 16 inches.
Plugging these values into the formula, we get:
[tex]V = (1/3)\pi(4.5 in)^2(16 in)\\\\= (1/3)\pi(20.25 in^2)(16 in)[/tex]
≈ [tex]341.4 in^3[/tex]
Rounding this answer to the nearest tenth of a unit, we get:

The diagram below shows a large square with two smaller squares within it.
(Diagram)
Write an expression, involving exponents, to calculate the shaded area, in square inches, of the diagram. Then use that expression to calculate the shaded area, in square inches, of the diagram.
The shaded area of the diagram is 23 square inches when side of large square is 6 inches.
What is square ?
A square is a geometrical shape that has four sides of equal length and four angles of 90 degrees each. It is a two-dimensional polygon with four vertices or corners. The area of a square can be calculated by multiplying the length of one of its sides by itself (i.e., squaring it) using the formula
[tex]A = s^2[/tex] , where A is the area and s is the length of one side of the square.
To calculate the shaded area, we need to subtract the area of the two small squares from the area of the large square and then subtract the area of the unshaded region (which is the area of the two overlapping squares).
The area of the large square is:
[tex]$(6\text{ in})^2 = 36\text{ in}^2$[/tex]
The area of the two small squares is:
[tex]$(2\text{ in})^2 + (3\text{ in})^2 = 4\text{ in}^2 + 9\text{ in}^2 = 13\text{ in}^2$[/tex]
Therefore, the expression for the shaded area is:
[tex]$36\text{ in}^2 - 13\text{ in}^2[/tex]
Simplifying this expression, we get:
[tex]$23\text{ in}^2$[/tex]
Therefore, the shaded area of the diagram is 23 square inches.
