Step-by-step explanation:
Hope this helps! (:
Using the arrangements formula, it is found that you can make 12 different 4 digit combinations with the numbers 1, 4, 8 and 8.
What is the arrangements formula?The number of possible arrangements of n elements is given by the factorial of n, that is:
\(A_n = n!\)
When there are repeating elements, repeating \(n_1, n_2, \cdots, n_n\) times, the number of arrangements is given by:
\(A_n^{n_1, n_2, \cdots n_n} = \frac{n!}{n_1!n_2! \cdots n_n!}\)
In this problem, there are 4 digits, one of which repeats twice, hence the number of arrangements is given by:
\(A_{4}^{2} = \frac{4!}{2!} = 12\)

The pie chart shows the results of surveying 200 college students to find out how many hours they worked per week at a job.
Hello! Firstly, let's get the important information from the exercise and write them here:
• more than 15 hours: 103 students
,• 15 hours or less: 85 students
,• didn't work: 12 students
,• total: 200 students
Now, let's calculate each alternative:
a. ratio of more than 15 to less than 15:To find the ratio, we will write the number of students who work more than 15 hours in the numerator, and in the denominator we will put the number of students who works less than 15 hours + students who didn't work, look:
\(\frac{103}{85+12}=\frac{103}{97}\cong1.06\)b. ratio of students without a job to students who work more than 15 hours:We'll solve in a similar way, look:
\(\frac{\text{without a job}}{\text{more than 15h}}=\frac{12}{103}\cong0.1165\)c. ratio of students with jobs to the total of students:\(\frac{103+85}{200}=\frac{188}{200}=\frac{47}{50}\cong0.94\)d. ratio of students with jobs to students without jobs:\(\frac{103+85}{12}=\frac{188}{12}=\frac{47}{3}\cong15.67\)

Jennie is standing 52 km away from the Volcano and the volcano is 2.4 km high. Assuming Makayla and the base of the volcano are at the same elevation above sea level, what is the angle of elevation from Makayla to the top of the volcan??
9514 1404 393
Answer:
2.64°
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
Here, the side of the right triangle in this geometry that is adjacent to the angle of elevation is the distance to the volcano: 52 km. The side opposite is the height of the volcano: 2.4 km. Then the angle α is found from ...
tan(α) = 2.4/52
α = arctan(2.4/52) ≈ 2.64°
The angle of elevation from Makayla's position is about 2.64°.
Answer:
Solution :-Since Jennie is standing away so,
\( \sf \: \tan( \arctan) = \dfrac{2.4}{52} \)
=> 2.64⁰
Find m/ABC.
A. 81°
B. 86°
C. 47°
D. 49.5°
99°
B
D
94%
The value of m ∠ABC=86° ,because of the cyclic quadrilaterals.
Hence, Option (B) is correct.
Since, We know that,
A cyclic quadrilateral is a four-sided polygon whose vertices all lie on a common circle.
The opposite angles of a cyclic quadrilateral have a total of 180°.
Hence, We can formulate;
m ∠ABC + m ∠ADC = 180°
m ∠ABC + 94° = 180°
m ∠ABC = 180° - 94°
m ∠ABC = 86°
Similarly, one can find m∠DCB
m∠DAB + m∠DCB = 180°
99° + m∠DCB = 180°
m∠DCB = 180° - 99°
m∠DCB = 81°
Hence, m∠ABC = 86°

A certain type of kickboard scooter comes in silver, red, 2
or purple with wheel sizes of 125 millimeters or 180
millimeters. Determine the total number of color-wheel size combinations.
(This is probability and I’m having such a hell of a time figuring it out pls help)
There are a total of 8 color-wheel size combinations for the kickboard scooter. This means that customers have 8 different options to choose from when selecting the color and wheel size for their scooter.
To determine the total number of color-wheel size combinations for the kickboard scooter, we need to multiply the number of color options by the number of wheel size options.
Given that there are 4 color options (silver, red, blue, and purple) and 2 wheel size options (125mm and 180mm), we can use the multiplication principle to find the total number of combinations:
Total combinations = Number of color options × Number of wheel size options
Total combinations = 4 colors × 2 wheel sizes
Total combinations = 8

A classroom has 28 students, 11 of these students are boys. If a student is randomly
chosen, what's the probability that the student will be a girl? Round
Answer:
Probability that student will be a girl = 17 / 28
Step-by-step explanation:
Given:
Total number of student = 28 student
Number of boys in the class = 11
Find:
Probability that student will be a girl = ?
Computation:
⇒ Number of girls in class = Total number of student - Number of boys in the class
⇒ Number of girls in class = 28 - 11
⇒ Number of girls in class = 17
⇒ Probability that student will be a girl = Number of girls in class / Total number of student
⇒ Probability that student will be a girl = 17 / 28

The length of the arc is proportional to the central angle.
CircumferenceThe circumference of the circle is given by ...
C = 2πr
C = 2π(8 in) = 16π in ≈ 50.265 in
Shorter arcThe 60° arc represents 60°/360° = 1/6 of the circle, so its measure will be 1/6 of the total circumference.
short arc = (1/6)(16π in) ≈ 8.38 in
Longer arcThe remaining portion of the circle is 5/6 of the total circumference, so is ...
long arc = (5/6)(16π in) ≈ 41.89 in

Find the volume of the cone. Round your answer to the nearest hundredth
Answer:
\(V=8042.47\ cm^3\)
Step-by-step explanation:
Given that,
The radius of the cone, r = 16 cm
The height of the cone, h = 30 cm
The slant height of the cone, l = 34 cm
We need to find the volume of the cone. The formula for the volume of a cone is given by :
\(V=\dfrac{1}{3}\pi r^2 h\)
Put all the values,
\(V=\dfrac{1}{3}\times \pi \times (16)^2 \times 30\\\\V=8042.47\ cm^3\)
So, the volume of the cone is equal to \(8042.47\ cm^3\).

A recipe calls for 2 cup of brown sugar for every 6 cups of white sugar. How many cups of brown sugar are required for every 12 cups of white sugar?
(PLEASE HELP!!)
There are 4 cups of brown sugar are required for every 12 cups of white sugar.
A recipe calls for 2 cups of brown sugar for every 6 cups of white sugar. We can set up a proportion to find the relationship between the two quantities:
2 cups brown sugar / 6 cups white sugar = x cups brown sugar / 12 cups white sugar
To find the number of cups of brown sugar required for 12 cups of white sugar, we can cross-multiply and then solve for x:
2 cups brown sugar × 12 cups white sugar = 6 cups white sugar × x cups brown sugar
24 cups brown sugar = 6x cups brown sugar
x = 24/6
x = 4
So, 4 cups of brown sugar are required for every 12 cups of white sugar.

are the following that correspond to a probability of an event occurring.
When the null hypothesis is assumed to be true, the p-value of a chi squared value of 4 represents the likelihood of receiving a test statistic at least as extreme as the observed one. This depicts how likely it is that the event will occur.
The possibility of the event occurring is represented by the probability of seeing 50 successes in 50 binomial trials, which is the probability of success in each trial multiplied by the quantity of trials.
Since it represents the region under a continuous probability distribution function rather than the likelihood of a discrete event, the integral of the density of the chi-squared distribution between and does not represent the likelihood that an event will occur.
Similar to the probability density of the chi squared distribution, the probability density of the chi squared distribution measures the likelihood that a random variable will have a value within a given range even when the chi-squared value does not correspond to a probability of an event occurring.

what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Lauren paid $30 for the jacket on sale.
What is Percentage?Percentage of any number is calculated by dividing the number with the whole and then multiplying the result with 100.
Similarly the opposite steps can be used to find the original number out of the percentage.
So percentage is the ratio or number which can be expressed as a fraction of 100 or in simple terms, percentage is the part per 100.
The symbol we use to denote percentage is %.
Lauren bought a jacket that was on sale.
Original price of the jacket = $75
Amount Lauren paid is the 40% of the original price $75.
Actual price paid = 40% × 75
= (40/100) × 75
= 0.4 × 75
= 30
That is the actual price is $30.
Hence, if Lauren paid 40% of the original price $75, then the amount Lauren paid for the jacket is $30.
