Answer:
Should be 70 since <B is also 70
Step-by-step explanation:
Going by the diagram, you just read the value of x. The value of y requires a little bit of calculation. x=70 degree
Step-by-step explanation: Step One
Find x
You just read the value.
x is the same as the 70 degree angle. That comes about from parallel lines.
x = 70 degrees. <<<< answer
Step Two
Find y
All triangles have 180 degrees.
So ABC has 180 degrees.
70 + 50 + <ACB = 180 Combine like terms
120 + <ACB = 180 Subtract 120 from both sides
<ACB = 180 - 120
<ACB = 60
y = <ACB
y = 60 degrees. <<<< Answer.

Answers
Answer:
a-1. The predicted price of a house with ocean views and square footage of 2,000 is $411,500.00.
a-2. The predicted price of a house with ocean views and square footage of 3,000 is $531,500.00.
b-1. The predicted price (in $1,000s) of a house without ocean views and square footage of 2,000 is $358,900.
b-2. The predicted price of a house without ocean views and square footage of 3,000 is $478,900.00.
c. The correct option is An ocean view increases the value of a house by approximately $52,600.
Step-by-step explanation:
Given:
yˆ = 118.90 + 0.12x + 52.60d ………………. (1)
a-1. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 2,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 2,000
d = 1
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 2000) + (52.60 * 1) = 411.50
Since the predicted price is in $1,000s, we have:
yˆ = 411.50 * $1000
yˆ = $411,500.00
Therefore, the predicted price of a house with ocean views and square footage of 2,000 is $411,500.00.
a-2. Compute the predicted price (in $1,000s) of a house with ocean views and square footage of 3,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 3,000
d = 1
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 3,000) + (52.60 * 1) = 531.50
Since the predicted price is in $1,000s, we have:
yˆ = 531.50 * $1000
yˆ = $531,500.00
Therefore, the predicted price of a house with ocean views and square footage of 3,000 is $531,500.00.
b-1. Compute the predicted price (in $1,000s) of a house without ocean views and square footage of 2,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 2,000
d = 0
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 2000) + (52.60 * 0) = 358.90
Since the predicted price is in $1,000s, we have:
yˆ = 358.90 * $1000
yˆ = $358,900.00
Therefore, the predicted price of a house without ocean views and square footage of 2,000 is $358,900.00.
b-2. Compute the predicted price (in $1,000s) of a house without ocean views and square footage of 3,000. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)
This implies that we have:
x = 3,000
d = 0
Substituting the values into equation (1), we have:
yˆ = 118.90 + (0.12 * 3,000) + (52.60 * 0) = 478.90
Since the predicted price is in $1,000s, we have:
yˆ = 478.90 * $1000
yˆ = $478,900.00
Therefore, the predicted price of a house without ocean views and square footage of 3,000 is $478,900.00.
c. Discuss the impact of ocean views on the house price.
Since the coefficient of d in equation (1) is 52.60 and positive, and the predicted price is in $1,000s; the correct option is An ocean view increases the value of a house by approximately $52,600.

Square root 3 sin theta = -3 cos theta
Answers
Answer:
Step-by-step explanation:
hello : the equation is : √3 sinθ= -3 cosθ means :
sinθ/cosθ = -3/√3
sinθ/cosθ = - √3 because : 3 =√3 ×√3
but : sinθ/cosθ = tan θ
tan θ = - √3 and - √3 = tan( π - π/3) = tan(2 π/3)
you have : tan θ = tan(2 π/3)
note : tanx=tany means : x= y + k π ... k in Z
so : all solutions in R are θ = 2 π/3+k π ... k in Z
d(x³+4x)/dx find the derivative ?
Answers
Answer:
3x²+4
Step-by-step explanation:
To find the derivative of something with respect to x, for each term multiply the power on the x in that term by the coefficient in the same term, and then lower the x's power by one.
For example, if we had to find the derivative of 2x³, we would first multiply the power on the x (3) by the coefficient (2): 6x³. Then lower the x's power by one: 6x². So the derivative of 2x³ is 6x².
To find the derivative an expression with several terms added together, you just do the same for each terms.

Answers
Answer:
The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
Step-by-step explanation:
A newsletter publisher believes that 60`% of their readers own a Rolls Royce.
This means that the null hypothesis is: [tex]H_{0}: p = 0.6[/tex]
That is, that the proportion of their readers who own a Rolls Royce is of 0.6.
A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim.
The alternate hypothesis is: [tex]H_{a}: p \neq 0.6[/tex]
After performing a test at the 0.020.02 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher's claim?

a. If the alternative hypothesis is true, the probability of observing a test statistic of 3.34 or greater is 0.001.
b. If the null hypothesis is true, the probability of observing a test statistic at least as extreme as 3.34 is 0.001.
c. If the null hypothesis is true, the probability of observing a test statistic of 3.34 or greater is 0.001This answer is incorrect.
d. If the alternative hypothesis is true, the probability of observing a test statistic at least as extreme as 3.34 is 0.001.
e. If the null hypothesis is true, the probability of observing a test statistic of 3.34 is 0.001.
Answers
Answer:
C
Step-by-step explanation:
The test produced, a t-value of 3.34 and a p-value of 0.001 as a result. The possibility of seeing a test statistic at least as extreme as 3.34 is 0.001; the proper reading of the p-value is different if the alternative hypothesis is true.
Probability calculation:p-value = 0.001
t = 3.34
Whether the alternative theory is true because there is a 0.001, and the possibility of showing testing statistics as extreme as 3.34.The p-value indicates that since the Null-hypothesis is true, there is a 0.001 chance of seeing a test statistic at least as extreme as 3.34.Therefore, the final answer is "Option d".

Answers
Answer:
the required probability is 0.0357
Step-by-step explanation:
Given the data in the question;
X-Exp( λ = 40/60 = 0.6667
Pdf: f( x ) = λe^(-λx), 0 < x
so
Cdf: P( X < x ) = 1 - e^(-λe)
( X ≤ x ) = 1 - e^(-λe), for x > 0 ⇒ p( X > x ) = e^(-λe)
now to wait at least 5 minutes before seen another
p(X > 5 ) = e^(-λe)
we substitute
p(X > 5 ) = e^(-0.6667 × 5)
p(X > 5 ) = e^(-3.3335)
p(X > 5 ) = 0.035668 ≈ 0.0357
Therefore, the required probability is 0.0357

Answer:
(x +6)^2 +(y -10)^2 = 225
Step-by-step explanation:
The standard form equation for a circle is ...
(x -h)^2 + (y -k)^2 = r^2
where the center is (h, k) and the radius is r.
The center of a circle is the midpoint of any diameter. The midpoint between two points is the average of their coordinates.
((-15, -2) +(3, 22))/2 = (-15+3, -2+22)/2 = (-6, 10)
The radius can be found using the distance formula, or by simply putting one of the given points in the equation for the circle to see what the constant (r^2) needs to be.
(x -(-6))^2 +(y -10)^2 = (-15-(-6))^2 +(-2-10)^2
(x +6)^2 +(y -10)^2 = 81 +144 = 225
The equation of the circle is ...
(x +6)^2 +(y -10)^2 = 225
