Answer:
x = 40
Step-by-step explanation:
since lines PQ and BC are parallel , then
∠ BCQ and ∠ AQP are corresponding angle and are congruent , that is
∠ BCQ = 80°
the sum of the 3 angles in Δ ABC = 180° , then
x + 80 + 60 = 180
x + 140 = 180 ( subtract 140 from both sides )
x = 40

A real estate company is interested in testing whether the mean time that families in Gotham have been living in their current homes is less than families in Metropolis. Assume that the two population variances are equal. A random sample of 100 families from Gotham and a random sample of 150 families in Metropolis yield the following data on length of residence in current homes.
Gotham: XG = 35 months, SG2 = 900 Metropolis: XM= 50 months, SM2 = 105
Q1: Referring to Scenario 10-3, suppose ΅ = 0.10. Which of the following represents the result of the relevant hypothesis test?
A) The null hypothesis is rejected.
B)The alternative hypothesis is rejected.
C) The null hypothesis is not rejected.
D) Insufficient information exists on which to make a decision.
Q2: Referring to Scenario 10-3, suppose a = 0.10. Which of the following represents the correct conclusion?
A) There is not enough evidence that the mean amount of time families in Gotham have been living in their current homes is not less than families in Metropolis.
B)There is enough evidence that the mean amount of time families in Gotham have been living in their current homes is less than families in Metropolis.
C) There is not enough evidence that the mean amount of time families in Gotham have been living in their current homes is less than families in Metropolis.

D) There is not enough evidence that the mean amount of time families in Gotham have been living in their current homes is less than families in Metropolis.
Answers
Answer:
the answer d , the second answer is b, the third answer is b,
Step-by-step explanation:
Q1. Option D is correct, Insufficient information exists on which to make a decision.
Q2. Option B is correct, There is enough evidence that the mean amount of time families in Gotham have been living in their current homes is less than families in Metropolis.
Q3. Option A is correct, There is not enough evidence that the mean amount of time families in Gotham have been living in their current homes is not less than families in Metropolis.
In the given scenario, a real estate company wants to compare the mean time that families in Gotham and Metropolis have been living in their current homes.
A random sample of 100 families from Gotham and 150 families from Metropolis is taken, and the data is provided as follows:
Gotham: XG = 35 months, SG² = 900
Metropolis: XM = 50 months, SM²= 105
To test the hypothesis, we need to set up the null hypothesis (H₀) and the alternative hypothesis (H₁). In this case:
H₀: The mean time families in Gotham have been living in their current homes is equal to the mean time in Metropolis (μG = μM).
H₁: The mean time families in Gotham have been living in their current homes is less than the mean time in Metropolis (μG < μM).
Q1: The result of the relevant hypothesis test cannot be determined without the test statistic and critical value.
So, Insufficient information exists on which to make a decision.
Q2: With a significance level of α = 0.10, if we reject the null hypothesis, we can conclude that there is enough evidence to support the alternative hypothesis.
In this case, the alternative hypothesis states that the mean time in Gotham is less than the mean time in Metropolis.
The correct conclusion is there is enough evidence that the mean amount of time families in Gotham have been living in their current homes is less than families in Metropolis.
Q3: With a smaller significance level of α = 0.01, we need stronger evidence to reject the null hypothesis.
If we fail to reject the null hypothesis, we cannot conclude in favor of the alternative hypothesis.
The correct conclusion is there is not enough evidence that the mean amount of time families in Gotham have been living in their current homes is not less than families in Metropolis.

What percent larger is 20.49 trillion to 13.4 trillion
Answers
The answer of the given question based on the percent is , 20.49 trillion is about 52.84% larger than 13.4 trillion.
What is Percentage?Percentage is a way of expressing a quantity or value as a fraction of 100. It is a widely used method for describing proportions, rates, changes, and comparisons in various fields such as mathematics, economics, statistics, science, and everyday life. The term "percent" literally means "per hundred", and it is represented by the symbol "%". To convert a number to a percentage, we multiply it by 100 and add the symbol "%".
To find the percent larger that 20.49 trillion is to 13.4 trillion, we can use the following formula:
Percent change = (New value -Old value) /Old value * 100%
Plugging in the values we have:
Percent change = (20.49 trillion - 13.4 trillion) / 13.4 trillion * 100%
= 7.09 trillion / 13.4 trillion * 100%
= 52.84%
Therefore, 20.49 trillion is about 52.84% larger than 13.4 trillion.

If Talia sells $2.5 million of software during one year, what are Talia’s earnings for that year?
Answers
Answer:
$131250
Step-by-step explanation:
Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)
Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%
2,500,000 ÷ 100 = 25000
Step 2. Multiply this number by the specific percentage (2.65)
25000 x 2.65 = 66250
Now add the commission and the yearly salary
65000 + 66250 = 131250
Hence, total earnings of Talia were $131250

Let (-3,-2) be a point on the terminal side of theta. Find the csc(theta)
Answers
The csc(theta) = 1/sin(theta) = 1/(-2/√13) = -√13/2. So, the cosecant of theta is -√13/2.
To find the cosecant (csc) of theta when a point (-3, -2) lies on its terminal side, we need to determine the hypotenuse (r) of the right triangle formed by this point.
Using the Pythagorean theorem, r^2 = (-3)^2 + (-2)^2. So, r^2 = 9 + 4 = 13, and r = √13.
The csc(theta) is the reciprocal of sin(theta). Sin(theta) is calculated as the ratio of the opposite side (y-coordinate) to the hypotenuse, or sin(theta) = -2/√13.

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.6 years with a standard deviation of 0.9 years. If a sampling distribution is created using samples of the ages at which 49 children begin reading. What would be the mean of the sampling distribution?
Answers
Answer:
The value is \(\mu_{x} = 5.6 \ years\)
Step-by-step explanation:
From the question we are told that
The population mean is \(\mu = 5.6 \ years\)
The standard deviation is \(\sigma = 0.9 \ years\)
The sample size is n = 49
Generally given that the sample size is large enough, the sampling distribution created using the samples of the ages at which 49 children begin reading is equal to the population mean
i.e
\(\mu_{x} = \mu\)
=> \(\mu_{x} = 5.6 \ years\)

Need Help
Answers
Answer: -27
Step-by-step explanation: Use inductive reasoning to predict the most probable next number in the list.
3, 9, -3, 3, -9, -3, -15, -9, -21, ?
We can start by looking at the differences between consecutive terms in the list:
9 - 3 = 6 -3 - 9 = -12 3 - (-3) = 6 -9 - 3 = -12 -3 - (-9) = 6 -15 - (-3) = -12 -9 - (-15) = 6 -21 - (-9) = -12
Notice that the differences alternate between positive 6 and negative 12. This suggests that the pattern involves adding 6, then subtracting 12, and then adding 6 again. Applying this pattern to the last term in the list (-21), we get:
-21 + 6 = -15 -15 - 12 = -27 -27 + 6 = -21
Therefore, we predict that the most probable next number in the list is -27.

Answers
The three equations that pass through the points (–4, –16) and (5, 2) are equation 2 ,equation 3 and equation 4.
Given points:
(-4,-16) and (5,2).
slope m = y2-y1/x2-x1
= 2-(-16) / 5-(-4)
= 2+16 / 5+4
= 18/9
m = 2.
compare the given equations with standard equation y-y1 = m(x-x1)
Equation 1.
y + 4 = 2(x - 16)
y - (-4) = 2(x - 16)
on comparing we get,
m = 2
substitute (-4,-16) we get,
-16 + 4 = 2(-4 - 16)
-12 ≠ -40
this equation does not passes through the given points.
Equation 2.
y - 2 = 2(x -5)
here m = 2
substitute (-4,-16) we get,
-16 - 2 = 2(-4 - 5)
-18 = 18.
substitute (5,2) we get,
2 - 2 = 2(5 - 5)
0 = 0.
so this equation passes through the given points.
Equation 3.
y = 2x - 8
here m = 2
substitute (-4,-16) we get,
-16 = 2(-4) - 8
-16 = -16.
since slope of both equations is same if it passes through one point it can definitely passes through the another point.
so this equation passes through the given points.
Equation 4.
y + 16 = 2(x+4)
here m = 2
substitute (-4,-16) we get,
-16+16 = 2(-4+4)
0 = 0
since slope of both equations is same if it passes through one point it can definitely passes through the another point.
so this equation passes through the given points.
Therefore the three equations that pass through the points (–4, –16) and (5, 2) are equation 2 ,equation 3 and equation 4.

Four sparking plugs and a fan belt cost $10.50 if the fen belt costs $1.75 more than sparking plugs. Find the cost of each material
Answers
Answer: x = $1.75
Step-by-step explanation:
Let's assume that the cost of each sparking plug is x dollars. Then, the cost of the fan belt is x + $1.75 since it costs $1.75 more than each sparking plug.
According to the problem, the total cost of four sparking plugs and a fan belt is $10.50. We can express this as an equation:
4x + (x + $1.75) = $10.50
Simplifying and solving for x, we get:
5x + $1.75 = $10.50
5x = $8.75
x = $1.75
Therefore, each sparking plug costs $1.75 and the fan belt costs $3.50 ($1.75 + $1.75).
