The correct answer is option C: [tex]\(k + 4 = 16\).[/tex] This linear equation represents the relationship between Tina and Kai's volunteer times.
To represent the given situation, the equation that correctly represents the relationship between Tina's volunteer times (Tina = 16) and Kai's volunteer times (Kai = k) is:
[tex]\[Tina = Kai + 4\][/tex]
In this equation, Tina's volunteer times are represented by "Tina," and Kai's volunteer times are represented by "Kai." Since Tina has volunteered 4 more times than Kai, we add 4 to Kai's volunteer times to get the total number of times Tina has volunteered.
Substituting the given values, we have:
[tex]\[16 = k + 4\][/tex]
This equation represents the fact that Tina has volunteered [tex]16[/tex] times, which is equal to Kai's volunteer times (k) plus the additional 4 times that Tina volunteered.
Simplifying the equation:
[tex]\[k + 4 = 16\][/tex]
This equation is equivalent to the original equation and represents the relationship between Tina and Kai's volunteer times. Hence, the correct answer is option C: [tex]\(k + 4 = 16\).[/tex]

Muya had a 6 2/3hectares piece of land. .He donated 7/8hectares to a school, and 1 1/2 to a children's home. The rest of the land was shared equally between his son and daughter .Find the size of the land
The size of the land that Muya's son and daughter received is [tex]1\frac{11}{12}[/tex] hectares.
We can see that, Muya started with a [tex]6\frac{2}{3}[/tex] hectares piece of land, which we can write as an improper fraction i.e.:
[tex]6\frac{2}{3}[/tex] = (6 × 3 + 2) / 3 = [tex]\frac{20}{3}[/tex] hectares
The Muya donated [tex]\frac{7}{8}[/tex] hectares to a school and [tex]1 \frac{1}{2}[/tex] hectares to a children's home. The total amount of land he donated is:
[tex]= \frac{7}{8}+ \frac{11}{2} \\\\= \frac{7}{8} + \frac{3}{2} \\\\= \frac{14}{8} + \frac{12}{8} \\\\= \frac{26}{8} \\\\= \frac{13}{4} hectares[/tex]
The size of the land left is:

According to the NCAA, 12.8% of high school men's lacrosse players will end up playing at the collegiate level. If 20 male high school lacrosse payers are selected at random, find the probability that exactly four of them will play at the college lacrosse. Express your answer as a probability between C and 1 and round to three decimal places.
This question involves using the binomial distribution.
Let X be the number of male high school lacrosse players who will play at the college level out of the 20 selected players . We can model X as a binomial random variable with parameters n=20 and p=0.128, where p is the probability of success (i.e., a player going on to play at the college level).
The probability of exactly 4 players playing at the college level is given by the formula:
P(X=4) = (20 choose 4) * (0.128)^4 * (1-0.128)^(20-4)
Using a calculator, we can evaluate this expression to find:
P(X=4) = 0.155
Therefore, the probability that exactly four of the 20 male high school lacrosse players selected at random will end up playing at the college level is 0.155, or between C and 1 (inclusive).
Note that we rounded to three decimal places as requested .
the data in the table fits an exponential model of the form f(x)=ab^x+k. How could you use the data to find b and justify your answer algebraically?
The given data shows the values of x and f(x) for a function. The values of x are -4, -3, -2, -1, 0, and 1, whereas the corresponding values of f(x) are 138.6, 23.4, -5.4, -12.6, -14.4, and -14.85.
The exponential model for the given data is:
f(x) = abˣ + k = 14.85 + 18.638(0.169)ˣ
Let's choose the points (-4, 138.6) and (-3, 23.4):
[tex]f(-4) = ab^{(-4)} + k = 138.6\\f(-3) = ab^{(-3)} + k = 23.4[/tex]
Now we can subtract the second equation from the first equation to eliminate k:
[tex]f(-4) - f(-3) = ab^{(-4)} - ab^{(-3)}[/tex]
Simplifying this equation gives:
[tex]138.6 - 23.4 = a(b^{(-3)} - b^{(-4)})\\115.2 = a(b^{(-3)} - b^{(-4)})[/tex]
Next, we can divide the second equation by the first equation to eliminate a:
[tex]\dfrac{f(-3)}{f(-4)} = (ab^{(-3)} + k)/(ab^{(-4)} + k)\\\dfrac{23.4}{138.6} = b^1[/tex]
Solving for b gives:
[tex]b = (23.4/138.6)^{(1/1)}\\b = 0.169[/tex]
Now that we have found b, we can use one of the original equations to solve for a. Let's use the equation f(1) = ab¹ + k:
f(1) = ab¹ + k
-14.85 = a(0.169) + k
Solving for a gives:
a = (-14.85 - k)/(0.169)
To find k, we can substitute the value of a and b into any of the original equations. Let's use the equation f(0) = ab⁰ + k:
f(0) = ab⁰ + k
-14.4 = a(1) + k
-14.4 = a + k
Substituting the value of a into this equation gives:
-14.4 = (-14.85 - k)/(0.169) + k
-14.4 = -88.157 + 5.988k
k = 18.638
Therefore, the exponential model for the given data is:
f(x) = abˣ + k = 14.85 + 18.638(0.169)ˣ

First, we need to arrange the data in order. We can convert the mixed numbers to improper fractions for ease of comparison:
1/3, 2/1, 4/1, 1/1, 7/3, 4/5, 5/2
Now, let's arrange them in ascending order:
1/3, 4/5, 1, 7/3, 2, 5/2, 4
The median is the middle value in the data set. Since we have an odd number of values, the median is the middle value when the data is arranged in order. Therefore, the median is:
median = 2
Therefore, the correct option is C
Answer:
1.5
Step-by-step explanation:
1/3 2 4 1 7 2/3 4/5 5/2
Write the numbers in ascending order.
1/3 2/3 4/5 1 2 5/2 4 7
The median is the middle value if there is an odd number of numbers.
If there is an even number of numbers, the median is the mean of the middle two numbers.
Here, there are 8 values, so we do the mean of the middle 2 values.
median = (1 + 2)/2
median = 1.5

Answer:
(a) width = 71 ft; (b) length = 77 ft
Step-by-step explanation:
(a) The formula for area of a rectangle is
A = lw, where
A is the area in units squaredl is the lengthw is the widthBecause we're already given the area and length, we can find the width by plugging everything into the formula and solve for width, w:
6319 = 89w
71 ft = w
(b) The formula for perimeter of a rectangle is
P = 2l + 2w, where
P is the perimeterl is the lengthw is the widthSince we're given the perimeter and width this time, we can plug everything into the formula and solve for l:
272 = 2l + 2(59)
272 = 2l + 118
154 = 2l
77 ft = l
We can check our answers for (a) and (b) by plugging in the length and width for (a) into the area formula and seeing whether we get 6319 and plugging in the length and width for (b) into the perimeter formula and seeing whether we get 272
Checking answers for (a):
6319 = 89 * 71
6319 = 272
Checking answers for (b):
272 = 2(77) + 2(59)
272 = 154 + 118
272 = 272

3x+3y+3z=k
How does this equation equal 42?
Answer:
3(x + y + z) = k
z = k\/3 - x - y
-k + 3 x + 3 y + 3 z = 0
The value of k that makes the equation 3x + 3y + 3z = k equal to 42 is k = 14. When you substitute k = 14 into the equation, you get 3x + 3y + 3z = 42, which satisfies the condition.
To find the value of k that makes the equation 3x + 3y + 3z = k equal to 42, you need to solve for k.
The equation is:
3x + 3y + 3z = k
Now, we want this equation to equal 42, so we substitute 42 for k:
3x + 3y + 3z = 42
Next, we can simplify the equation by factoring out the common factor of 3 on the left side:
3(x + y + z) = 42.
Now, we have a simpler equation:
x + y + z = 42 / 3
Divide both sides by 3:
x + y + z = 14
So, to make the equation 3x + 3y + 3z = k equal to 42, k should be equal to 14.

Find the volume of this cylinder.
Give your answer to 1 decimal place.
11 cm
14 cm
The volume of the cylinder is approximately 1335.7 cm³.
To find the volume of a cylinder, we can use the formula:
Volume =[tex]\pi \times r^2 \times h[/tex]
Where π is a constant approximately equal to 3.14159, r is the radius of the cylinder, and h is the height or length of the cylinder.
Given that the diameter of the cylinder is 11 cm, we can find the radius by dividing the diameter by 2:
Radius = 11 cm / 2 = 5.5 cm
The length or height of the cylinder is given as 14 cm.
Now we can plug these values into the volume formula:
Volume = [tex]\pi \times (5.5 cm)^2 \times 14 cm[/tex]
Calculating this equation, we get:
Volume ≈ 3.14159 [tex]\times[/tex] [tex](5.5 cm)^2 \times[/tex] 14 cm

jerseys. How many jerseys can they purchase for $430?
The number of jerseys that the senior class at Legion Academy can purchase for $430, using quadratic equation, is 190.
What is quadratic equation?Quadratic equation is an algebraic equation of the second degree in x, represented in the form of ax²+bx+c=0.
In the quadratic equation, a, b, and c are known values but a ≠ 0 and x is unknown.
Quadratic Equation Formula:x = [-b ± √b² - 4ac]/2a
when ax^2 + bx + c = 0
Equation Model:C = 0 .1x² + 2.4x + 25, where C is the amount, it costs to buy x jerseys.

The probability that a student takes a history class given that the student is taking a science class is 0.59 to the nearest hundredth.
What is the probability?The probability that a student takes a history class given that the student is taking a science class is a conditional probability.
Assuming;
P(H) = Probability of taking a history class
P(S) = Probability of taking a science class
P(H ∩ S) = Probability of taking both a history class and a science class
Given data:
P(H ∩ S) = 0.48
P(S) = 0.82
Solving for P(H | S) using the formula for conditional probability:
P(H | S) = P(H ∩ S) / P(S)
P(H | S) = 0.48 / 0.82
P(H | S) ≈ 0.59
