38
15
What does the relative frequency of represent in the situation?

Out of all the children, 15 prefer a hike.
Out of all the family members that prefer a Mike, 15 are children.
Out of all the family members that prefer the lake, 15 are children.
Answers
The relative frequency of 15/24 for this considered situation represents the situation given by: Option C: Out of all the family members that prefer a lake, 15 are children.
How to find the relative frequency?Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency). (subgroup being group defined by a row, or a column)
How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as [tex]X_1, X_2, ... , X_n[/tex] and some values of Y are there as [tex]Y_1, Y_2, ... , Y_n[/tex]
List them in title of the rows and left to the columns. There will be [tex]n \times k[/tex] table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of [tex]X_i[/tex] and [tex]Y_j[/tex] (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
The given two-way frequency table is:
Lake Hike Total
Children 6
Adults 9
Total 14 38
Total of hike subgroup is 14, out of which children are 6, so adults going for hiking must be 14 - 6 = 8 as adults and children going for hiking together are 14 in counts.
So, we get:
n(Hike ∩ Children) = 8
Thus, the total of subgroup Adults is 9+8=17 = n(Adults)
Total of vertical total columns is: n(Children) + n(Adults) = 38
or, we get: n(Children) = 38 - 17= 21
Since total of children subgroup is:
n(Lake ∩ Children) + n(Hike ∩ Children) = n(Children)
Thus, we get:
n(Lake ∩ Children) + 6 = 21
n(Lake ∩ Children) = 21-6 = 15
Thus, sum of the 'lake' subgroup is:
n(Lake) = n( Lake ∩ Children) + n(Lake ∩ Adults)
n(Lake) = 15 + 9 = 24
Thus, the completed two-way table is:
Lake Hike Total
Children 15 6 21
Adults 9 8 17
Total 24 14 38
Now, we've to find what does 15/24 represents.
The division is done by 24, which is the total of "lake" subgroup.
And in that lake subgroup, we have:
n(Lake ∩ Children) = 15
Thus, 15/24 is the relative frequency of those children who prefer the lake, relative to total number of people who prefer lake.
Thus, the relative frequency of 15/24 for this considered situation represents the situation given by: Option C: Out of all the family members that prefer a lake, 15 are children.

The height of an object after it is released can be modeled by the function f (x) = negative 16 t squared v t s, where t is the number of seconds after the object is released, v is the upward speed in feet per second at release, and s is the starting height in feet. if a quarterback throws a ball from his hand 6 feet in the air at an upward speed of 25 feet per second, how much time does his teammate have to catch the ball?
Answers
The amount of time his teammate have to catch the ball is equal to 1.774 seconds.
Given the following function:
f(x) = -16t² + vt + s.Displacement, s = 6ft.Velocity, v = 25 ft/s.How to calculate the amount of time?In order to determine the amount of time his teammate have to catch the ball, we would evaluate the given position-time function as follows:
f(t) = -16t² + 25t + 6.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c =0
Where:
a = -16.
b = 25.
c = 6.
Solving the function by using the quadratic formula, we have:
t = [-b ± √(b² - 4ac)]/2a
t = [-25 ± √[(25² - 4(-16)(6))]/2(-16)
t = [25/32 ± (-1/32)√1009]
t = 25/32 ± (-0.993)
t = 0.781 ± 0.993
t = 0.781 + 0.993
Time, t = 1.774 seconds.
Note: We ignored the negative value because time cannot be negative.

Step-by-step explanation:
on plato
The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.
What is the equation of the parabola?The equation can be written as
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix.
Here, We have the upward parabola;
(h, k) = (-9, 7) and p = (7 - (-9))/ 2 = 8.
So the equation is
f(x) = 1/32(x + 9)^2 + 19
The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.

how many triangles can you make with side lengths of 17, 23, 13
Answers
Answer:
10 triangles
Step-by-step explanation:
Let’s consider three scenarios: an equilateral triangle, isosceles and scalene.
1. There are three possibilities for equilateral triangle: 13, 13, 13 17,17,17 23, 23, 23
2. There are 6 possibilities for a isosceles triangle:
There are three choices for the base and for the remaining two sides there are two choice, so 3 x 2 = 6
3. There is only one possibility for a scalene triangle:
Let’s use the triangle theorems to check:
Let the sides be 23,17 and 13. Since every other scalene triangle will have the same sides the SSS (Side-Side-Side) theorem states that any triangle with the same three sides is the same triangle (congruent).
Therefore when adding the three scenarios we will get 3 + 6 + 1 = 10 triangles that can be made.
The sum of two complex numbers is −3 + 5i. If one of the complex numbers is 1−8i, which answer choice below is the other number?
Answers
Answer:
C
Solution
For a complex number written in the form a + bi, a is called the real part of the complex number and b is called the imaginary part. The sum of two complex numbers, a + bi and c + di, is found by adding real parts and imaginary parts, respectively, that is, (a + bi) + (c + di) = (a + c) + (b + d)i. Therefore, the sum of 2 + 3i and 4 + 8i is (2 + 4) + (3 + 8)i = 6 + 11i.
Choice A is incorrect and is the result of disregarding i and adding all parts of the two complex numbers together, 2 + 3 + 4 + 8 = 17. Choice B is incorrect and is the result of adding all parts of the two complex numbers together and multiplying the sum by i. Choice D is incorrect and is the result of multiplying the real parts and imaginary parts of the two complex numbers, (2)(4) = 8 and (3)(8) = 24, instead of adding those parts together.

Answers
The residual value is the difference in the value of the y coordinate between the real value and the expected value. The residual value will be equal to -0.86.
What is residual value?The residual value is the difference in the value of y coordinate between the real value and the expected value.
Residual Value = Real value of y - The predicted value of y
The value of y in the table is -2 when the value of x is 5. And as per the function, the value of y when the value of x is 5 can be written as,
[tex]y = -0.7x+2.36\\\\y = -0.7(5)+2.36\\\\y= -3.5+2.36\\\\y=-1.14[/tex]
Now, the residual value can be written as,
[tex]\text{Residual Value} = \text{(Value of y in the table)} - \text{(Value of y as per the function)}\\\\\text{Residual value} = -2 - (-1.14)\\\\\text{Residual value} = -2+1.14\\\\\text{Residual value} = -0.86[/tex]
Hence, the residual value will be equal to -0.86.

Item 5 A six-sided number cube is rolled, and then a spinner with 5 equal sections labeled A through E is spun. What is the probability of rolling a number less than 4 and spinning a D? 115 110 215 710
Answers
Answer 1/10
Step-by-step explanation:
I took the quiz.
The probability of rolling a number less than 4 and spinning a D is 1/10 or 0.10. The correct answer is option B.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Since there are 6 sections on the number cube, the probability of rolling a number less than 4 is 3/6 or 1/2.
The spinner has 5 equal sections labeled A through E, so the probability of spinning a D is 1/5.
To find the probability of both events happening, we multiply the probabilities of each event:
(1/2) x (1/5) = 1/10
Therefore, the probability of rolling a number less than 4 and spinning a D is 1/10 or 0.10.

The value of b is 4 and the function becomes y = 2x²-12x+8 because (2, -8) lie on the function.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have:
[tex]\rm y = 2x^2+bx+8[/tex]
The above function shows the equation of the parabola.
From the graph, we can see the point(2, -8) lie on the graph of the function,
So point(2, -8) will satisfy the function.
Plug y = -8 and x = 2 in the function.
[tex]\rm -8 = 2(2)^2+b(2)+8\\\\-16 = 8+2b\\-24 = 2b \\b = -12[/tex]
Thus, the value of b is 4 and the function becomes y = 2x²-12x+8 because (2, -8) lie on the function.
