Answer:
D. 23/27
Step-by-step explanation:
The good news is, they wrote out all the possible options for you.
There are 27 possibilities in all, so that's our denominator.
They want to know which possibilities have a W in there OR an R comes first. So we'll count up the possibilities that start with R. There are 9.
Then, of the remaining 18, 14 include a W somewhere in there.
9 + 14 = 23 out of 27.
We are not counting the Ws in the possibilities that start with R, because of the OR in the sentence.

Using the logarithm quotient rule, it can be simplified to log1 - logA. Since log1 = 0 for any base, this simplifies further to -logA.
We simplify and solve the given expressions using the mentioned terms. Here are the step-by-step explanations for each expression:
1. logA: This expression represents the logarithm of a number A to a specified base. Without any base provided, it cannot be simplified further.
2. 1logAA: Since the coefficient of the logarithm is 1, this simplifies to logAA, which represents the logarithm of A to the base A. By definition, logAA = 1.
3. logA x Blog (a/b): This expression seems to have formatting issues, so I'll break it down into two separate expressions: - logA x B: This represents the logarithm of the product AB to a specified base. Using the logarithm product rule, it can be simplified to logA + logB. - log (a/b): This represents the logarithm of the quotient a/b to a specified base. Using the logarithm quotient rule, it can be simplified to loga - logb.
4. log A ^ B: This expression represents the logarithm of A raised to the power of B to a specified base. Using the logarithm power rule, it can be simplified to B * logA. 5. log 1/A: This expression represents the logarithm of the reciprocal of A (1/A) to a specified base.
Using the logarithm quotient rule, it can be simplified to log1 - logA. Since log1 = 0 for any base, this simplifies further to -logA.

Marisa has 26 pokémon cards. Marisa claims that she will have 146 or more pokémon cards after she receives her shipment of 8 packs of cards. How many cards must be in each pack so that Marissa’s statement is true?
Answer:
26 + 8x.x = 15.Step-by-step explanation:
Marise has 26 pokemon cards. Marisa claims that he will have 146 or more cards after she receives her shipment of 8 packs of cards.
So, we have to make a unknown value on 8.
8x.Now, we have to find out that unknown value:
26 + 8x= 26 + 8(15)= 26 + 120= 146.x = 15.There will be 15 cards in Marisa's 8 boxes.
In an all boys school, the heights of the student body are normally distributed with a mean of 70 inches and a standard deviation of 3.5 inches. Out of the 1019 boys who go to that school, how many would be expected to be shorter than 67 inches tall, to the nearest whole number?
We use the normal distribution formula and standard normal distribution table to find the proportion of boys in a school with heights shorter than 67 inches.
To solve this problem, we need to use the normal distribution formula and the standard normal distribution table.
First, we need to convert the height of 67 inches into a standard score or a z-score. The formula to calculate the z-score is:
z = (x - μ) / σ
where x is the height we want to convert, μ is the mean height of the population, and σ is the standard deviation.
So, for x = 67, μ = 70, and σ = 3.5, we have:
z = (67 - 70) / 3.5 = -0.8571
Next, we need to find the area under the standard normal distribution curve to the left of the z-score -0.8571 using the standard normal distribution table. This area represents the proportion of boys in the school who are shorter than 67 inches.
The table gives us that the area to the left of -0.8571 is 0.1950.
Finally, we need to multiply this proportion by the total number of boys in the school to find the expected number of boys who are shorter than 67 inches tall:
Expected number = proportion * total number of boys
Expected number = 0.1950 * 1019
Expected number ≈ 199
Therefore, to the nearest whole number, we can expect about 199 boys in the school to be shorter than 67 inches tall.

The polygons are similar but not necessarily drawn to scale.
If two polygons are similar, then they have the same shape but not necessarily the same size.
They can be either enlarged or reduced in size or reflected. Hence, even though the polygons are similar, they do not have to be drawn to scale.
The term scale refers to the ratio of any two corresponding lengths in two geometric figures, so if two figures are drawn to scale, the ratio of their corresponding lengths in the drawing is the same as the ratio of their corresponding lengths in the actual figures.
Therefore, if two polygons are similar but not drawn to scale, the drawing may not be an accurate representation of the actual figures, as the scaling information may not be consistent.

find the values of constants a, b, and c so that the graph of y=ax3 bx2 cx has a local maximum at x=4, local minimum at x=2, and inflection point at (3,−18).
The values of a, b, and c are a = 0, b = 0, and c = 0 respectively. Hence, the given function is:y = 0x³ + 0x² + 0x = 0.
Given equation:y=ax³+bx²+cx
The first derivative of the given function is obtained by differentiating the function with respect to x.
Then, it is equal to zero, we get the critical points, where maximum or minimum occurs.
The second derivative of the function is obtained to determine the nature of these critical points, whether it is maximum, minimum, or point of inflection.
First derivative:y'(x) = 3ax² + 2bx + c
At the local maximum at x = 4, the first derivative of the function must be equal to zero. Therefore, y'(4) = 0.
This can be expressed as:
3a(4²) + 2b(4) + c = 0
⇒ 48a + 8b + c = 0
At the local minimum at x = 2, the first derivative of the function must be equal to zero.
Therefore, y'(2) = 0. This can be expressed as:
3a(2²) + 2b(2) + c = 0
⇒ 12a + 4b + c = 0
Using these two equations above, we can obtain the values of a, b and c in terms of one unknown. By substituting the value of c in terms of a and b into the equation 48a + 8b + c = 0 obtained by using the local maximum condition, we get:
48a + 8b - 12a - 4b = 0
⇒ 36a + 4b = 0
⇒ 9a + b = 0
⇒ b = -9a
By substituting the value of b in terms of a into the equation 12a + 4b + c = 0 obtained by using the local minimum condition, we get:
12a + 4(-9a) + c = 0
⇒ c = 60a
Using these values for b and c, the given function can be expressed as:y = ax³ - 9ax² + 60
a.The second derivative of the function is given by: y''(x) = 6ax + 2b.
The inflection point is given by (3, -18).
Therefore,y''(3) = 0 ⇒ 6a(3) + 2b = 0 ⇒ 18a + 2b = 0 ⇒ 9a + b = 0 ⇒ b = -9a.
By substituting the value of b in terms of a, we get: 18a + 2(-9a) = 0 ⇒ a = 0.
Now that we have obtained the value of a, we can use it to find the values of b and c. We have:
b = -9
a = 0
c = 60
a = 0
Therefore, the values of a, b, and c are a = 0, b = 0, and c = 0 respectively. Hence, the given function is:y = 0x³ + 0x² + 0x = 0.

suppose that a family has 4 children.? also, suppose that the probability of having a girl is one half. find the probability that the family has no more than 3 boys.
The probability that a family with 4 children has no more than 3 boys is 15/16.
To find the probability that a family with 4 children has no more than 3 boys, we can use the binomial distribution.
The binomial distribution is used to calculate the probability of obtaining a certain number of successes (boys in this case) in a fixed number of trials (children in this case), where each trial has only two possible outcomes (boy or girl) and the trials are independent.
Let X be the number of boys in the family. We want to find P(X ≤ 3), which is the probability of having no more than 3 boys. Since the probability of having a boy is 1/2 and the trials are independent, we can use the binomial distribution formula:
P(X ≤ 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
= (1/2)⁴ + 4(1/2)⁴ + 6(1/2)⁴ + 4(1/2)⁴

Find the x of the angle
Answer:
74 degrees
Hope this helps and have a great day :)
And please mark me brainliest if you can :)
Answer:
74 degrees
Step-by-step explanation:
These two triangles are isosceles.
This means that the top angle of the left triangle is also 53 degrees.
All triangles have 180 degrees.
When we subtract 2(53) from 180 we get 74.
We can use this vertical angle to find out the angle left of x which is 74.
Since the second triangle is also isosceles, x is equal to 74 degrees.

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg
What is a unit amount in math?
When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio
1 k + 6.6 k = 617.3
Where “k” is a constant value, a multiplier.
Solving for k:
7.8 k = 617.3
k = 617.3 /7.8
k= 79.17
So:
Amount of onion used:
1 (79.17) = 79.17 kg

(a) Consider the family of curves given by the polar equations r sin(n), where n is a positive integer. How is the number of loops related to n? Check all that apply. A. There are 4n loops when n is odd. B. There are 2n loops when n is even. C. There are n loops when n is odd. D. There is exactly 1 loop for each n. E. There are n loops when n is even. F. There are no loops. G. There are 4n loops when n is even H. There are 2n loops when n is odd.
The correct answers are option C for when n is odd and option E for when n is even.
The number of loops in the polar curves given by r sin(n), where n is a positive integer, is related to the parity of n. If n is odd, then the curve will have n loops, and if n is even, the curve will have 2n loops. Therefore, options C and E are correct.
To understand why this is the case, we can consider how the sine function behaves. The sine function oscillates between -1 and 1 as its argument increases from 0 to 2π. When n is odd, the argument of sin(nθ) increases from 0 to 2π as θ goes from 0 to π, resulting in n oscillations of the sine function in this interval. When n is even, the argument of sin(nθ) increases from 0 to 4π as θ goes from 0 to π, resulting in 2n oscillations of the sine function in this interval. This behavior translates into the number of loops in the polar curve, where each oscillation of the sine function corresponds to one loop.
Therefore, the number of loops in the polar curve r sin(n) depends on the parity of n, with n loops for odd values of n and 2n loops for even values of n.

Answer:
"I Only" is the correct answer
Step-by-step explanation:
Given inequality is:
-10>3x-6
In order to check which numbers are solution to the given inequality, we will put each number one by one in the inequality. If the inequality is true after putting the number, the number is the solution of the inequality.
So,
I . -10
Putting -10 in the inequality
\(-10>3x-6\\-10>3(-10)-6\\-10>-30-6\\-10> -36\)
The inequality results in true after putting x=-10 so -10 is the solution of inequality.
II. 5
Putting 5 in the inequality
\(-10>3x-6\\-10>3(5)-6\\-10>15-6\\-10>9\)
The equality doesn't hold true for x=5 so 5 is not the solution of the problem.
III. -1
Putting -1 in the equation
\(-10>3x-6\\-10>3(-1)-6\\-10>-3-6\\-10>-9\)
Inequality doesn't hold true for x=-1 so it is not the solution of the inequality.
Hence,
"I Only" is the correct answer as only -10 is the solution of inequality.
