Answer:
100°
Step-by-step explanation:
tThe sum of all arc measures that make up that circle is 360 degrees.
QS + RQ + RS = 360
QS = 360 - 120 - 140 = 100
An arc angle is the degree measurement of that angle inside the circle, opposite the arc
m∠R = arc QS = 100°
Answer:
∠ R = 50°
Step-by-step explanation:
the inscribed angle R is half the measure of its intercepted arc QS
the sum of the arcs on a circle is 360° , that is
RQ + QS + SR = 360°
120° + QS + 140° = 360°
QS + 260° = 360° ( subtract 260° from both sides )
QS = 100°
Then
∠ R = \(\frac{1}{2}\) × 100° = 50°

question researchers are studying the distribution of subscribers to a certain streaming service in different populations. from a random sample of 200 people in city c, 34 were found to subscribe to the streaming service. from a random sample of 200 people in city k, 54 were found to subscribe to the streaming service. assuming all conditions for inference are met, which of the following is a 90 percent confidence interval for the difference in population proportions (city c minus city k) who subscribe to the streaming service?
The 90 percent confidence interval for the difference in population proportions (City C minus City K) who subscribe to the streaming service is option (a) 0.07 ± 0.086
A confidence interval is a range of values that we are fairly sure contains the true value of a population parameter.
To estimate this difference, they took random samples of 200 people from each city and found the proportion of subscribers in each sample. Now, they want to construct a 90 percent confidence interval for the difference in population proportions (City C minus City K) who subscribe to the streaming service.
To do this, we need to use a formula that takes into account the sample proportions, the sample sizes, and the desired level of confidence (in this case, 90 percent). The formula for the confidence interval for the difference in population proportions is:
(sample proportion 1 - sample proportion 2) ± (critical value) × (standard error)
The critical value is based on the desired level of confidence and the degrees of freedom (df), which is the sum of the sample sizes minus 2. In this case, the critical value is 1.645.
The standard error is a measure of how much the sample proportions might vary from the true population proportions. It is calculated as:
sqrt[(sample proportion 1 × (1 - sample proportion 1) / sample size 1) + (sample proportion 2 × (1 - sample proportion 2) / sample size 2)]
Using the sample proportions and sample sizes given in the problem, we can calculate the standard error to be 0.052.
Now, we can plug in these values into the formula and simplify to get the confidence interval:
(0.34 - 0.27) ± 1.645 × 0.052
0.07 ± 0.086
This means we are 90 percent confident that the true difference in population proportions of subscribers to the streaming service between City C and City K is somewhere between 0.016 and 0.124. Note that this interval does not include 0, which suggests that there is a significant difference between the two cities in terms of subscribers to the streaming service.
So, the option (a) is the correct one.

Find the x
Answer:
x = 18
Step-by-step explanation:
There are 2 ways to do this :
1) Method 1 :
sum of exterior angles of a triangle = 360
⇒ (9x - 31) + (4x + 33) + (7x - 2) = 360
⇒ 20x = 360
⇒ x = 360/20
⇒ x = 18
2) Method 2:
Since the three lines are straight lines, the interior angles of the triangle are given by:
∠CDE = 180 - (9x - 31) = 211 - 9x
∠DEC = 180 - (4x + 33) = 147 - 4x
∠ECD = 180 - (7x - 2) = 182 - 7x
The sum of angles in a triangle = 180
∠CDE + ∠DEC + ∠ECD = 180
⇒ 211 - 9x + 147 - 4x + 182 - 7x = 180
⇒ 540 - 20x = 180
⇒ 20x = 540 - 180
⇒ 20x = 360
⇒ x = 360/20
⇒ x = 18

Find the path of a heat-seeking particle placed at point P on a metal plate with a temperature field T(x,y). Temperature Field: T(x,y)= 100 - x^(2) - 2y^(2).
As a result, the following parametric equations describe the motion of the heat-seeking particle: x = a - 2t and y = b - 4t
As per the question given,
To find the path of a heat-seeking particle placed at point P on a metal plate with a temperature field T(x,y) = 100 - x^(2) - 2y^(2), we need to use the gradient vector of T(x,y).
The gradient of T(x,y) is given by:
∇T(x,y) = (-2x, -4y)
The heat-seeking particle moves in the direction of maximum increase of temperature, so it moves in the direction of the gradient vector, that is, (-2x, -4y).
To find the path of the particle, we need to integrate the gradient vector starting at point P = (a,b), where a and b are the coordinates of the point on the metal plate where the particle is placed.
So the path of the heat-seeking particle is given by the following parametric equations:
x = a - 2t
y = b - 4t
where t is the parameter that represents time.
These equations represent a straight line in the direction of the gradient vector of T(x,y). The particle moves from point P in the direction of the gradient vector, with a speed proportional to the magnitude of the gradient vector.

How is the quotient of 8,552 and 16 determined using an area model?
Enter your answers in the Question marks to complete the equations.
8,552 ÷ 16 = ( ? ÷ 16) + ( 480 ÷ 16 ) + ( ? ÷ 16 ) + (8÷16)
8,552 ÷ 16 = ? + 30 + ? + 8/16
8,552 ÷ 16 = ? 1/2
The expression 8552/16 is solved using area model below.
What are expressions?
Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
Now,
8,552 ÷ 16 = ( ? ÷ 16) + ( 480 ÷ 16 ) + ( ? ÷ 16 ) + (8÷16)
1. 8,552 ÷ 16=8000/16+480/16+64/16+8/16

describe how a graph would look for the solution set for the inequality in problem 5. describe what the solution means and how the price of the balloons bought will affect the amount in the budget.
A)
i) the inequality to show the number of ballons that the dance committee can buy is: 0.80b + 65 ≤ 125
ii) solving the inequality above, we arrive at b ≤ 75
B) The graph is attached accordingly.
C) See the description of the solution below.
Let's start by defining our variables. Let b be the number of balloons that the dance committee could buy.
The cost of b balloons is $0.80b. We want to make sure that the cost of the balloons plus the amount already spent on decorations ($65) is less than or equal to the budget of $125. So we can write the following inequality:
0.80b + 65 ≤ 125
Now we can solve for b:
0.80b + 65 ≤ 125
0.80b ≤ 125 - 65
0.80b ≤ 60
b ≤ 75
Therefore, the dance committee can buy up to 75 balloons to stay within their budget.
To graph the solution set, we can plot b on the horizontal axis and shade the region to the left of b = 75, since b must be less than or equal to 75.
The solution set represents all possible values of b that satisfy the inequality. In this case, the solution set is b ≤ 75, which means that the dance committee can buy up to 75 balloons and still stay within their budget.
As the number of balloons increases, the cost of the balloons also increases, and the amount of money left in the budget decreases.
Therefore, the more balloons the dance committee buys, the less money they will have left for other decorations or expenses.

This is the previous problem: A rabbit started at point 0 and made 3 jumps a jump of 4 units then a jump of 2 units and then a jump of 1 unit we do not know the direction of either jump where on the line could the rabbit be.
Since the rabbit from the previous problem started at 10, it would be at 17 units on the number line after the same three jumps.
What is a number line?In Mathematics, a number line is a type of graph with a graduated straight line which comprises both positive and negative numerical values that are placed at equal intervals along its length.
From the previous problem, the total distance covered by the rabbit is given by:
Total distance = 4 units + 2 units + 1 unit
Total distance = 7 units.

Answer/Step-by-step explanation:
a. First, find the value of a.
Sum of the interior angles of a triangle = 180° (triangle sum theorem)
Therefore:
3a + 2a + a = 180°
Add like terms
6a = 180°
6a/6 = 180/6
a = 30
Thus:
a = 30°
2a = 2(30) = 60°
3a = 3(30) = 90°
b. The triangle is an isosceles triangle because it has two sides that are indicated to be equal. This also implies that the angels opposite each of the equal sides are also congruent to each other.
Therefore, sum of the isosceles triangle would be:
2(2x) + 5x = 180°
4x + 5x = 180
9x = 180
9x/9 = 180/9
x = 20
Thus:
2x = 2(20) = 40
5x = 5(20) = 100

A man's gross income is R500 000. He worked at different places throughout the year
and a total of 17% of his earnings was deducted by his employers as PAYE throughout
the tax year. He qualifies for a rebate of R13 257. Calculate how much tax he still
owes. Information taken from the tax table shows that, for a taxable income between
R393 201 and R550 100, R93 135 + 36% above R393 200 needs to be paid.
O R101 678
O R71 774
O R33 326
O R25 191
<
Previou
Next >
The man still owes R87,726 in taxes.
To calculate the tax amount the man still owes, we need to determine his taxable income first.
Gross income: R500,000
Less: PAYE deductions (17% of gross income): R500,000 * 0.17 = R85,000
Taxable income: R500,000 - R85,000 = R415,000
Next, we can use the tax table information provided to calculate the tax owed based on the taxable income.
Tax owed: R93,135 + 36% of (taxable income - R393,200)
Tax owed: R93,135 + 0.36 * (R415,000 - R393,200)
Tax owed: R93,135 + 0.36 * R21,800
Tax owed: R93,135 + R7,848
Tax owed: R100,983
Finally, we subtract the rebate amount of R13,257 from the tax owed to find the amount the man still owes.
Tax owed - Rebate: R100,983 - R13,257 = R87,726
Therefore, the man still owes R87,726 in taxes.
