It's D, because the mean doesn't matter as much if it's only taken in a small variability. The mean was selected from 25 random pages in the book, that is why it is right.
Answer:
Yes, because the mean is larger in the math book.Step-by-step explanation:
According to Kim's calculations
The mean of the Math Book is 49.9, this means there are 49.9 per page.The mean of the Poetry Book is 41.5, which means there are 41.5 per page.Remember that a mean is defined as the quotient between the sum of all elements and the total number.
According to this calculations, the Math Book has more words per page, based on its greater mean.
Therefore, the right answer is the first choice.

A student has successfully passed 60 percent of the 20 quizzes he has written so far. If the student writes 50 quizzes during the year, and successfully passes 80 percent of the remaining quizzes, what is his percent success rate for all his quizzes for the entire year? help
Answer:
74.29%
Step-by-step explanation:
A student passed 60%, or a proportion of 0.60 of the 20 quizzes he's written so far. This means he has passed [tex]0.60*20=12[/tex] quizzes so far.
Now he has written 50 quizzes and passed 80% of them, or [tex]50*.8=40[/tex] quizzes.
To find the success rate, take the number of quizzes passed and divide by total number of quizzes.
[tex]\frac{Passed}{Total}[/tex]=[tex]\frac{12+40}{20+50}[/tex]=[tex]\frac{52}{70}[/tex]=.7429
To get a percentage, multiply this proportion by 100 to get 74.29%

Anthony observes that when people are leaving class, about 50% turn left and about 50% turn right. Anthony wants to estimate the probability that fewer than 3 of the first 4 students will turn left when leaving class tomorrow. To do this, he lets H represent turning left when leaving class and T represent turning right. He then flips a coin 4 times, recording the results. He repeats this process for a total of 20 trials. HHTT THHT HTTT HTHH HHTT HTHT THTH TTHH HHHH HTTH HHHT TTHT THHH THTH HHTT HTTT HTTH HHTT HTHH HHTH Drag and drop the correct fraction to the box to estimate the probability, using this simulation. Estimated probability that fewer than 3 of the first 4 students leaving class tomorrow will turn left:
The fact that Anthony repeats the test [tex]n[/tex] times doesn't change anything, because he already know that you have a 50/50 chance of turning left of right.
Given that, Anthony observes that when people are leaving class, about 50% turn left and about 50% turn right.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
H represent turning left when leaving class and T represent turning right,
Both of them have a 50% probability of happening and he wants to know the probability of less than 3 turn left so we want to know the probability for only one to turn left and the probability for only two.
Only one:
If you use the fact that we have a binomial distribution, then the possibility that only one turns left is:
So, [tex]P(1)=\frac{4!}{3!} \times0.5^{4[/tex]
= 4×0.0625 = 0.25
Only two with the same reasoning.
[tex]P(2) = \frac{4!}{(2!\times2!)} \times0.0625=6\times0.0625 = 0.375[/tex]
Here you can see that the probability is bigger because here are mass combinations that in the previous case.
So the total probability is 0.25 + 0.375 = 0.625.
The fact that he repeats the test [tex]n[/tex] times doesn't change nothing, because he already know that you have a 50/50 chance of turning left of right.

if cos a = 3/5 in the first quadrant, what does cot a equal
Final answer:
To find cot a when cos a = 3/5 in the first quadrant, we first determine the length of the opposite side using the Pythagorean theorem, which gives us 4. Subsequently, cot a is calculated as the ratio of the adjacent to the opposite side, resulting in cot a = 3/4.
Explanation:
If cos a = 3/5 in the first quadrant, we use trigonometric identities to find cot a. First, recognize that in a right triangle, the Pythagorean theorem states a² + b² = c². Given cos a = adjacent/hypotenuse = 3/5, and the fact that we are in the first quadrant (where all trigonometric values are positive), we can solve for the opposite side using the Pythagorean theorem.
Let the opposite side be b, the adjacent side (corresponding to cos a) be 3, and the hypotenuse be 5. The equation becomes b² + 3² = 5² which simplifies to b² = 25 - 9 = 16, giving b = 4.
We know that cot a = adjacent/opposite = cos a / sin a. Thus, sin a = b / hypotenuse = 4/5. Therefore, cot a = 3/4.

A hamster wheel has a diameter of 8.5 in. How many inches does the hamster run in one revolution? Use 3.14 to approximate for π .
As hamster wheel is circular so for revolution we will find the circumference.
Diameter of the Hamster wheel = 8.5 in
One revolution of the wheel = circumference of the wheel
Circumference = π × d
π = 3.14 and d = 8.5
So, Circumference = 3.14 × 8.5
Circumference = 26.69 in
So in one revolution the hamster wheel travels a distance of 26.69 in

a car model comes with the following choices: 9 colors,with or without air conditioning,with or without sunroof ,with or without automatic transmission ,with or without a spoiler,and with or without anti lock brakes. in how many ways can it be ordered
There 288 ways the car can be ordered.
What is Combination?Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant.
Given:
There are five Categories as
with or without air conditioning,with or without sunroof ,with or without automatic transmission ,with or without a spoiler,and with or without anti lock brakes.Total colors for car= 9
Now, the possible number of ways can it be ordered
= 9 x 2 x 2 x 2 x 2 x 2
= 9 x 32
= 288 ways
Hence, there 288 ways the car can be ordered.

#SPJ2
Final answer:
To determine the number of ways a car model can be ordered based on given feature choices, multiply the number of options for each feature. In this case, it's 9 colors multiplied by 2 options for each of the 5 binary features (with or without), leading to a total of 288 different combinations.
Explanation:
To determine the number of different ways a car can be ordered based on the given options, we simply need to multiply the number of choices available for each feature.
First, there are 9 colors. Then for each feature such as air conditioning, sunroof, automatic transmission, spoiler, and anti-lock brakes, there are two options available: with or without.
So, for each of these five binary options (yes or no), we multiply the number of choices by 2 (with or without).
Colors: 9 choices
Air conditioning: 2 choices
Sunroof: 2 choices
Automatic transmission: 2 choices
Spoiler: 2 choices
Anti-lock brakes: 2 choices
Now, we can calculate the total number of ways the car can be ordered:
Total ways = 9 (colors) * 2 (air conditioning) * 2 (sunroof) * 2 (automatic transmission) * 2 (spoiler) * 2 (anti-lock brakes)
Total ways = 9 * 25 = 9 * 32 = 288.
Therefore, there are 288 different combinations in which the car can be ordered.

What’s $54.00 for 3 tickets in unit rate
according to the graph........
The solution is:
H(w) gets very small when w gets very large .
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
Here, we have,
Considering the graph H(w),
As w gets larger, H(w) continues to approach a horizontal asymptote.
we know that,
A horizontal asymptote of a graph is a horizontal line y = b where the graph approaches the line as the inputs approach ∞ or –∞. A slant asymptote of a graph is a slanted line y = mx + b where the graph approaches the line as the inputs approach ∞ or –∞.
Hence, H(w) gets very small.
Therefore, the correct option is option D
Hence, The solution is:
H(w) gets very small when w gets very large .
