Answer:
2/3
Step-by-step explanation:
To find the value of k, we can use the given information that y is 6 when x is 72. Plugging these values into the equation, we have:
6 = k * 72
To solve for k, we divide both sides of the equation by 72:
k = 6/72 = 1/12
Now that we know the value of k, we can use it to find the value of y when x is 8. Plugging x = 8 into the equation y = kx, we have:
y = (1/12) * 8 = 8/12 = 2/3
Therefore, when x is 8, y is 2/3.
A, B & C form the vertices of a triangle. ∠ CAB = 90°, ∠ ABC = 65° and AB = 8. 6. Calculate the length of BC rounded to 3 SF
The length of BC rounded to 3 significant figures is approximately 3.62 units.
We can use trigonometric function to find the length of BC. First, we can use the fact that ∠CAB = 90° to determine that ∠ACB = 25° (since the angles in a triangle sum to 180°).
Next, we can use the law of sines to relate the lengths of the sides and angles of the triangle:
sin(∠ABC) / AB = sin(∠ACB) / BC
Substituting in the values we know:
sin(65°) / 8.6 = sin(25°) / BC
Solving for BC:
BC = sin(25°) × 8.6 / sin(65°) ≈ 3.62
Rounding to 3 significant figures, we get BC ≈ 3.62 units

Answer:
x=70
z=20
y=30
Step-by-step explanation:
first find x: the sum of straight angle is 180
x+110=180
x=180-110=70
now find z: the sum of the angles of triangle is 180:
x=70, right angle=90
z+70+90=180
find y:
y+110+40=180
y=180-150=30
z=180-160=20
Answer:
x=70 degrees, y= 30 degrees, z=20 degrees
Step-by-step explanation:
110+x=180 => straight angle def.
180-110+40=y => def. of angles in triangle
x( 70 degrees) +90+z=180, z= 20 => angles in triangle

The cost of ordering shirts for a club is 268 units.
Define Function.
A function, according to a technical definition, is a relationship between a set of inputs and a set of possible outputs, where each input is connected to precisely one output.
This means that a function f will map an object x exactly to one object f(x) in the set of possible outputs if the object x is in the set of inputs (called the codomain).
The statement that f is a function from X to Y using the function notation f: X→Y
The function that represents the cost of the shirts(x) is f(x) = 8x+12
Now, for x = 32
f(x) = 8x+12
f(32) = 8(32) + 12

Find the average rate of change of the function f(x) = 3x from x₁ = 0 to x2 = 9.
The average rate of change is
The average rate of change of the function is 3.
What is the Average Rate of Change?The ratio of "change in the function values" to "change in the interval endpoints" is referred to as the average rate of change of a function f(x) over an interval [a, b]. Specifically, [f(b) - f(a)] can be used to get the average rate of change (b - a). The average rate of change, represented by the symbol A(x), is, in other words, the "ratio of change in outputs to change in inputs." i.e., A(x) = (change in outputs) / (change in inputs)= Δy / Δx = [f(b) - f(a)] / (b - a)
Given:
x₁ = 0
x₂ = 9
f(x) = 3x
f(x₁) = 0
f(x₂) = 27
Average rate of change, \(A(x) = \frac{f(x_{2})-f(x_{1} ) }{x_{2}-x_{1} }\)
Putting the values, we get
\(A(x) = \frac{27-0}{9-0}\) = \(\frac{27}{9}\) = 3
Therefore, the average rate of change is 3.

Write an integral that quantifies the change in the area of the surface of a cube when its side length triples from s unit to 3s units. 18 ) dx Evaluate the integra
The change in the area of the surface of the cube when its side length triples from s units to 3s units is 52s³.
To quantify the change in the area of the surface of a cube when its side length triples from s units to 3s units, we can set up an integral.
Let's denote the side length of the cube as "x". The initial side length is "s" and the final side length is "3s". We want to find the change in surface area, which is the difference between the final surface area and the initial surface area.
The surface area of a cube with side length "x" is given by 6x², as each face of the cube has an area of x² and there are 6 faces.
The change in surface area can be calculated as:
ΔA = ∫(6x²) dx,
where the integral is taken from the initial side length "s" to the final side length "3s".
Now let's evaluate the integral:
∫(6x²) dx = 2x³ + C,
where C is the constant of integration.
To find the change in surface area, we substitute the limits of integration:
ΔA = [2x³]s to 3s
= 2(3s)³ - 2s³
= 2(27)s³ - 2s³
= 52s³
Therefore, the change in the area of the surface of the cube when its side length triples from s units to 3s units is 52s³.

If the length of of one diagonal is of a rhombus of area is 96cm is 12cm,then what is the length of the other diagonal?
Given:
Area of rhombus = 96 cm
One diagonal = 12 cm
To find:
The other diagonal.
Solution:
We know that,
\(\text{Area of a rhombus}=\dfrac{1}{2}\times d_1\times d_2\)
where, \(d_1\text{ and }d_2\) are two diagonals of the rhombus.
Putting the given values, we get
\(96=\dfrac{1}{2}\times 12\times d_2\)
\(96=6\times d_2\)
Divide both sides by 6.
\(\dfrac{96}{6}=d_2\)
\(16=d_2\)
Therefore, the length of the other diagonal is 16 cm.
Return to the "Prestige" example used in previous questions. The least-squares regression equation is yˆy^ = -10.7 + 5.8x, where x = number of years of education, and yˆy^ = predicted prestige rating.
Suppose a person in the sample with 15 years of education has a residual of -5. What is this person's prestige rating?
To answer this question,
1. start by calculating and reporting this person's predicted prestige rating. Report your answer to ONE decimal place.
2. Use your answer to question 1 and information give above to determine the observed prestige rating for this person. Report your answer to ONE decimal place.
The predicted prestige rating for a person with 15 years of education, based on the least-squares regression equation, is 75.5. Given a residual of -5, the observed prestige rating for this person is 70.5.
The least-squares regression equation, y^ = -10.7 + 5.8x, relates the number of years of education (x) to the predicted prestige rating (y^). To find the predicted prestige rating for a person with 15 years of education, we substitute x = 15 into the equation:
y^ = -10.7 + 5.8(15)
y^ = -10.7 + 87
y^ = 76.3
Thus, the predicted prestige rating for this person is 76.3 (rounded to one decimal place). Now, we need to determine the observed prestige rating using the residual information. The residual represents the difference between the predicted and observed values. In this case, the residual is given as -5. Therefore, we subtract the residual from the predicted prestige rating to obtain the observed prestige rating:
Observed prestige rating = y^ - Residual
Observed prestige rating = 76.3 - (-5)
Observed prestige rating = 76.3 + 5
Observed prestige rating = 81.3
The observed prestige rating for this person, based on the given residual of -5, is 81.3 (rounded to one decimal place).

The statements that are true to determine whether x=10 is unusually high number of defective items on the next run of 100 products are given by the following option:
I and III.
What are unusually high measures in the binomial distribution?Unusual values in the normal distribution are found using the range rule of thumb, which states that if a value is more than two standard deviations from the mean, the measure is unusual.
The measures for the binomial distribution are given as follows:
E(X) = np.S(X) = sqrt(np(1 - p)).The parameters for this problem are given as follows:
n = 100, p = 0.04.
Then the mean and the standard deviation are given as follows:
Mean: 4.Standard deviation: 1.96.Thus the upper bound for usual values is of:
4 + 2 x 1.96 = 7.92.
Which is less than 10, hence 10 is an unusual measure and statement I is correct.
Statement III is also correct, as:
P(X >= 10) < 0.05.

The number of platters that can be made is 8.
Given that you need to make a platter which consists of 1 bagel, 2 eggs, and 3 slices of bacon. Since it is needed to calculate the maximum number of platters that can be made with 9 bagels, 17 eggs and a package of bacon containing 36 slices.
Further, If we make 1 platter then we need 1 bagels, 2 eggs and 3 slices of bacon. Therefore, for 8 platters, the material required would be 8 times of 1 platter, that is 8 bagels, 16 eggs and 24 slices of bacon.
Similarly if I have to create 9 platters , the material required would be 9 times of 1 platter, that is 9 bagels, 18 eggs and 27 slices of bacon.
So we can not make 9 platters because we need that one extra egg.
