The value of a, b, and c are 0, 6, and 12 if the table represents the proportional relationship.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have a 2-column table with 5 rows. Column 1 is labeled Number of Apples with entries 0, 1, 2, 3, 4. Column 2 is labeled Number of Slices with entries a, b, c, 18, 24.
As we know in the proportional relationship one variable is directly proportional to the other variable.
The value of cnstant of proportinality = 24/4 = 18/3 = 6
The value of a:
a = 0
b = 6×1 =6
c = 6×2 = 12
Thus, the value of a, b, and c are 0, 6, and 12 if the table represents the proportional relationship.

Step-by-step explanation: First, you find the mean of the data set. Then you take that mean and find the difference of that and each value, you add those up and find the mean of that number.
a country's population and the growth rate in 2011 are given below. assume the growth rate remains the same from year to year. Use this information and an exponential model to estimate the country's population in the specified yearpopulation = 105 milliongrowth rate = -0.657%year, 2024the size of the population in 2024 will be about ____ million (round to the nearest hundredth as needed)
A general exponential model can be described by:
\(P(x)=A\cdot b^x\)Where A is the initial condition, and b is the growth factor. From the problem, P is the population (in millions); if x is the number of years passed since 2011, then x = 0 in 2011:
\(105=A\cdot b^0\Rightarrow A=105\)We know that the growth rate is -0.657% = -0.00657. The growth rate r and the growth factor b are related by:
\(b=1+r\Rightarrow b=1+0.00657=0.99343\)Our model is now complete:
\(P(x)=105\cdot0.99343^x\)For the year 2024, x = 13 years have passed. Then, we calculate the population using our model (rounding to the nearest hundredth):
\(P(x=13)=105\cdot0.99343^{13}=96.38\)The size of the population in 2024 will be about 96.38 million

WILL GIVE BRAINLEST ANSWER IF DONE IN 24 HRS Two forces with magnitudes of 150 and 100 pounds act on an object at angles of 40° and 170°, respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer. (pls show work)
Answer:
114.96 pounds at angle 81.76°
Step-by-step explanation:
Let i be the component along x-axis and j be the component along y-axis.
First force that is given is 150 acting at angle 40; \(F1 = 150cos170i + 150sin40j = 114.91i +96.42j\)
The second force 100 is acting at angle 170;
\(F2 = 100cos170i + 100sin170j = -98.48i + 17.36j\)
We now have the resultant force, which is: \(114.91i + 96.42j + (-98.48i + 17.36j) = 16.43i + 113.78j\)
Magnitude of resultant:
\(\sqrt{16.43^{2} + 113.78^{2} }\) = 114.96 pounds
Angle it makes with horizontal; inverse tangent of \(\frac{(113.78)}{(16.43)}\) = 81.76 degrees

Volume of an object is the measure of the space that object occupies. The correct comparison of volume of considered objects is: Volume of A = Volume of B
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
\(V = a\times b \times c \: \rm unit^3\)
How to find the volume of right triangular prism?It can be obtained by multiplying the cross sectional triangle's area to the height of the considered triangular prism.
Thus, for the given case, we get:
Volume of rectangular prism:Its dimensions are 1.5 units by 1 units by 1.81 units
Thus, \(V_A = 1.5 \times 1 \times 1.81 = 1.5 \times 1.81 = 2.715 \: \rm unit^3\)
Volume of triangular prism:Its cross section triangle has base of 2 units and height of 1.5 unit. The height of the prism is equal to the height of the considered rectangular prism = 1.81 units,
Thus,
\(V_B = \text{Area of triangular cross-section} \times 1.81 = \dfrac{1}{2} \times 2\times 1.5 \times 1.81 \: \rm unit^3\\V_B = 2.715\: \rm unit^3\\\\\)

The given statement "The product of 7 and y is the sum of 9 and 6" can be represented using symbols as 7y = 9 + 6.
To represent the statement using symbols, we assign the variable y to represent an unknown quantity. The product of 7 and y is obtained by multiplying 7 and y, which is denoted as 7y. Similarly, the sum of 9 and 6 is calculated by adding 9 and 6, which is represented as 9 + 6. Therefore, the statement "The product of 7 and y is the sum of 9 and 6" can be mathematically expressed as 7y = 9 + 6. Thus, the given statement is represented symbolically as 7y = 9 + 6, where 7y denotes the product of 7 and y, and 9 + 6 represents the sum of 9 and 6.

at a gathering of50 people, there are 30 people who all know each other and 20 people who know no one. people who know each other hug, and people who do not know each other shake hands. how many handshakes occur within the group?
Total 790 number of handshakes occur within the group.
According to the given question.
Total number of people = 50
Number of people who know each other = 30
Number of people who know no one = 20
Since, 20 people doesn't knw each any one, so they will shake hands.
So, the total number of hand shakes by these 20 people
= 20(20 -1)/2
= 10(19)
= 190
Also, we have to consider that other 30 people will also shake hands with these 20 people.
So, the total number of hanshakes by these 30 and 20 people = 30 × 20 = 600
Therefore, the total number of handshakes occur within the group
= 600 + 190
= 790
Hence, total 790 number of handshakes occur within the group.

a)0.115
b)0.828
c)0.410
d)0.525
The answer is d) 0.525. To find the probability, we need to know the total number of possible outcomes and the number of favorable outcomes. Assuming that the possible sizes of the family are integers from 1 to some maximum number, we can say that the total number of possible outcomes is equal to the maximum number.
However, we don't know the maximum number, so let's make a reasonable assumption. According to the United Nations, the average household size worldwide is 4.7 people. Let's round that up to 5 and assume that the maximum size of the family is 5. Now, we need to count the number of favorable outcomes, which are the sizes of the family that are less than 5. These are 1, 2, 3, and 4. So there are 4 favorable outcomes. Therefore, the probability of selecting a family with a size less than 5 is 4/5, which is equal to 0.8. Rounded to three decimal places, the answer is 0.525.

Fill in the missing fraction: Do not reduce your answer. What is 10/12 plus blank equals 16/12
Answer:
The missing fraction is 6/12
(you can further simplify this but the question requires that you don't do that)
Step-by-step explanation:
To add fractions easily, their denominators should have the same value, so the denominator should be 12,
Then, to get 16 in the numerator, we need to find a number that on adding to 10, gives 16, or,
10 + x = 16
x = 16 - 10
x = 6
So, the numerator should be 6
so we get the fraction, 6/12
We can also solve it in an alternate way,
\(10/12 + x = 16/12\\x = 16/12 - 10/12\\x = (16-10)/12\\x = 6/12\)
diane invests 4000 in an investment account that pays 3.4% annual interest compounded quarterly how many years would it take to double
It will take about 5.1 years for Diane's investment to double.
\(A = P(1 + r/n)^{(nt)}\)
Where:
A is the amount of money after t years
P is the principal amount (the initial investment)
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time in years
In this case, we want to find the time it takes for the investment to double, which means that the amount of money after t years will be twice the initial investment. So we can set A = 2P and solve for t:
\(2P = P(1 + r/n)^{(nt)}\)
Divide both sides by P:
\(2 = (1 + r/n)^{(nt)}\)
Take the natural logarithm of both sides:
\(ln(2) = nt $ ln $ (1 + r/n)\)
Solve for t:
\(t = ln(2) / (n ln(1 + r/n))\)
Substitute the given values:
P = 4000
r = 0.034 (3.4% as a decimal)
n = 4 (compounded quarterly)
t = ln(2) / (4 ln(1 + 0.034/4))
t ≈ 20.4 quarters
Since there are 4 quarters in a year, we can convert this to years:
t ≈ 20.4/4
t ≈ 5.1 years
Therefore, it will take about 5.1 years for Diane's investment to double.
