The statement "S′H′ is parallel to S′Q′" is true.
How to find the correct statement?To find the image of the square after reflection across the x-axis, we need to flip each point of the square over the x-axis. The coordinates of the reflected points will have the same x-coordinate, but the y-coordinate will have the opposite sign.
The coordinates of the original square are:
S(−3,0)
H(2,0)
A(2,5)
Q(−3,5)
The coordinates of the reflected square are:
S′(−3,0)
H′(2,0)
A′(2,−5)
Q′(−3,−5)
Now, we can find the slopes of the sides of the reflected square to determine which sides are parallel.
S′H′¯¯¯¯¯¯¯¯¯¯¯: The slope of S′H′¯¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, S′H′¯¯¯¯¯¯¯¯¯¯¯ is parallel to the x-axis.
S′Q′¯¯¯¯¯¯¯¯¯¯: The slope of S′Q′¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, S′Q′¯¯¯¯¯¯¯¯¯¯ is also parallel to the x-axis.
H′A′¯¯¯¯¯¯¯¯¯¯¯: The slope of H′A′¯¯¯¯¯¯¯¯¯¯¯ is undefined, since the two points have the same x-coordinate. Therefore, H′A′¯¯¯¯¯¯¯¯¯¯¯ is parallel to the y-axis.
H′S′¯¯¯¯¯¯¯¯¯¯¯: The slope of H′S′¯¯¯¯¯¯¯¯¯¯¯ is also undefined, since the two points have the same x-coordinate. Therefore, H′S′¯¯¯¯¯¯¯¯¯¯¯ is parallel to the y-axis.
A′Q′¯¯¯¯¯¯¯¯¯¯: The slope of A′Q′¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, A′Q′¯¯¯¯¯¯¯¯¯¯ is parallel to the x-axis.
Q′S′¯¯¯¯¯¯¯¯¯¯: The slope of Q′S′¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, Q′S′¯¯¯¯¯¯¯¯¯¯ is also parallel to the x-axis.
Based on these calculations, we can see that S′H′¯¯¯¯¯¯¯¯¯¯¯ is parallel to S′Q′¯¯¯¯¯¯¯¯¯¯ (both are parallel to the x-axis). Therefore, the statement "S′H′¯¯¯¯¯¯¯¯¯¯¯ is parallel to S′Q′¯¯¯¯¯¯¯¯¯¯" is true.

If one of the test subjects is randomly selected, find the probability that the subject tested negative or did not use marijuana. (Hint: Construct a table.)
The probability that the subject tested negative or did not use marijuana is approximately 0.57.
What is probability?Probability is a branch of mathematics that deals with the study of random events and their likelihood of occurrence. It is a way of quantifying the uncertainty or randomness associated with an event or an experiment.
In the given question,
To solve this problem, we can construct a table that summarizes the given information:
We are given the following information:
There are 143 subjects with positive test results, of which 20 are false positives.
There are 153 subjects with negative test results, of which 4 are false negatives.
Using this information, we can fill in the table as follows:
The numbers in parentheses are the counts of subjects in each category.
To find the probability that the subject tested negative or did not use marijuana, we need to add the probabilities of the two mutually exclusive events:
Tested negative and did not use marijuana (True Negative): P(True Negative) = 149/296
Tested positive but did not use marijuana (False Positive): P(False Positive) = 20/296
Therefore, the probability that the subject tested negative or did not use marijuana is:
P(Tested Negative or Did not use marijuana) = P(True Negative) + P(False Positive)
= 149/296 + 20/296
= 169/296

Simplify. p/ab+2q/ac
Answer:
To simplify the expression p/ab+2q/ac, we need to find a common denominator for the two fractions in the denominator. The common denominator is abc.
Thus,
p/ab + 2q/ac
= p*c/abc + 2q*b/abc (multiplying the first fraction by c/c and the second fraction by b/b)
= pc/abc + 2qb/abc
= (pc + 2qb) / abc
Therefore, the simplified expression is (pc + 2qb) / abc.
The runtime of a certain brand of batteries is normally distributed with a population means of μ=30 hours and σ=6 hours. what is the probability that 16 randomly selected batteries will have a runtime of less than 27 hours?
The probability that 16 randomly selected batteries will have a runtime of less than 27 hours is 0.0228.
Describe Probability?Probability is a branch of mathematics that deals with the study of random events or outcomes. It involves the analysis of the likelihood or chance of a particular event occurring, given certain conditions or assumptions. Probability is expressed as a number between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.
Probability theory is used to analyze and understand random phenomena such as games of chance, weather patterns, financial markets, and many other areas of study. The main tools of probability theory include probability distributions, random variables, and statistical inference.
Probability distributions are mathematical functions that describe the probabilities of different outcomes for a particular event or experiment. Random variables are variables that take on different values based on the outcome of a random event, and they are used to calculate probabilities for a range of different scenarios.
We can use the central limit theorem to approximate the distribution of the sample means, where n=16. The sample mean, X', will also be normally distributed with a mean of μ = 30 hours and a standard deviation of σ/√n = 6/√16 = 1.5 hours.
Now, we need to find the probability that the sample mean is less than 27 hours:
P(X' < 27) = P(z < (27-30)/1.5) [converting to standard normal distribution using z-score]
P(X' < 27) = P(z < -2)
Looking up the z-table, we can find that the probability of a standard normal random variable being less than -2 is approximately 0.0228.
Therefore, the probability that 16 randomly selected batteries will have a runtime of less than 27 hours is 0.0228.

A sledding run is 280 yards long with a vertical drop of 18.5 yards. What is the angle of depression of the run?
thank you
Answer:
approximately 3.84 degrees.
Step-by-step explanation:
The angle of depression is the angle between a horizontal line and the line of sight when looking downwards. We can use trigonometry to calculate this angle.
Let's draw a diagram to represent the situation:
A
/|
/ |
18.5/ | 280
/ |
/θ |
/_____|
B
Here, point A represents the top of the sledding run, point B represents the bottom of the run, and θ is the angle of depression we want to find.
We can see that AB is the hypotenuse of a right triangle, and the vertical drop of 18.5 yards is the opposite side. We can use the tangent function to relate the opposite side to the adjacent side, which is the horizontal distance of the run:
tan θ = opposite/adjacent
tan θ = 18.5/280
Now we can use a calculator to find the value of the tangent:
θ = tan^(-1) (18.5/280)
θ ≈ 3.84 degrees
Therefore, the angle of depression of the run is approximately 3.84 degrees.
Anna is draining her bathtub which currently as 45 gallons of water in it . it drains at a rate 7 gallons every three minutes. how many gallons will it have after 5 minutes of draining?
Answer:
Bathtub currently has 45 gallons of water.
It drains 7 gallons every three minutes.
How much gallons will it have after 5 minutes.
First, find how much it drains in one minute and multiply it by 5.
7 gallons per 3 minutes.
So 7/3 = 2.3333 or roughly 2 gallons per minute.
How many gallons will it have after 5 minutes of draining.
2*5 = 10 litres will have been drained.
So, 45 - 10 = 35 gallons of water would remain after 5 minutes of draining.

√2x √x +3.
OA. √x² + 6x
OB. √2x2 + 3x
OC. √2x² + x
D. √2x² + 6x
Answer:
the answer is (C) √(2x² + x). None of the answer options match this expression, but we can simplify it to show that it is equivalent. option (C) √(2x² + x) is equivalent to the original expression √(2x) * √(x+3) when x > 0.
Step-by-step explanation:
To simplify the expression √(2x) * √(x+3), we can use the property of radicals that says:
√(a) * √(b) = √(a * b)
So, we have:
√(2x) * √(x+3) = √(2x * (x+3))
Multiplying out the terms inside the radical, we get:
√(2x * (x+3)) = √(2x² + 6x)
Therefore, the expression √(2x) * √(x+3) is equivalent to the radical expression √(2x² + 6x) when x > 0.
So, the answer is (C) √(2x² + x). None of the answer options match this expression, but we can simplify it to show that it is equivalent:
√(2x² + 6x) = √(2x² + x + 5x) = √(x * (2x + 5)) = √x * √(2x + 5)
What is the period, phase shift and cosine function of this graph

The period = π
The phase shift = π/8
The cosine function is; y = 2·cos(2·(x - π/8)) - 1
What is the period of the graph of the cosine function?The period of the graph is the distance between two consecutive peaks of the wave.
The maximum value of the graph is 1 at x = π/8 and x = 9·π/8, and the minimum value of the function is; -3 at 5·π/8.
The vertical displacement can be obtained from half the sum of the max and min point as follows;
Vertical displacement = (1 + (-3))/2 = -1
The vertical displacement = -1
The amplitude = Half the distance between the max and min point of the graph
Amplitude, a = (1 - (-3))/2 = 2

O is the center of the regular nonagon below. Find its perimeter. Round to the nearest tenth if necessary. Answer: P = = O 7 units
Therefore, the perimeter P of the nonagon is 19.5 units.
What is perimeter?Perimeter refers to the total length of the boundary or the outer edge of a closed figure or shape. It is the sum of the lengths of all the sides or edges that enclose the shape.
Here,
Since O is the center of the regular nonagon, all the sides of the nonagon are equal in length. Let the length of one side of the nonagon be s. Then, the perimeter P of the nonagon is given by:
P = 9s
To find s, we can use the fact that the sum of the interior angles of a nonagon is given by (9-2)×180° = 1260°. Since the nonagon is regular, each angle is equal to 1260°/9 = 140°.
Consider the triangle OAB, where A and B are two adjacent vertices of the nonagon. Since O is the center of the nonagon, angle AOB is equal to 360°/9 = 40°. Also, angle OAB and angle OBA are equal to half of (180° - 140°) = 20°.
Therefore, angle AOB is isosceles, and we can use the cosine rule to find s:
cos(20°) = (s/2) / s
cos(20°) = 1/2

The value of x in right angle whose hypotenuse is given 74 m one angle is 90° and other angle given is 30° to the nearest tenth is approximately 37 meters.
What is trigonometry?The branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right triangles is known as Trigonometry. It involves studying the properties of trigonometric functions, which are mathematical functions that relate the angles of a triangle to the ratios of its sides.
In this triangle, the height is opposite the 30° angle and the hypotenuse is the longest side of the triangle. We can use the trigonometric function sine to relate the height and the hypotenuse:
sin(30°) = x / 74
To solve for x, we can multiply both sides by 74 and simplify:
x = 74 sin(30°)
x ≈ 37 (to the nearest tenth)

The local cherry-picking farm charged Cameron $5.25 for 2 3/5 pounds of cherries. At that rate, how much would Cameron pay for 5.5 pounds of cherries?
Cameron would pay $11 for 5.5 pounds of cherries at the same rate.
What is simple interest?The interest on a loan or principal sum can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more.
We can start by finding the cost of cherries per pound:
2 3/5 pounds = (2 × 5 + 3) / 5 = 13/5 pounds
Cost of 13/5 pounds of cherries = $5.25
Cost of 1 pound of cherries = $5.25 ÷ (13/5) = $2
Now we can find the cost of 5.5 pounds of cherries:
Cost of 5.5 pounds of cherries = $2 × 5.5 = $11
Therefore, Cameron would pay $11 for 5.5 pounds of cherries at the same rate.

Which of the following is a ‘False’ statement.
(a) Two diameters of a circle will necessarily intersect.
(b) The centre of a circle always lies in the interior.
(c) The diameter is half of the radius of a circle.
(d) Longer chord is nearer to the centre of the circle.
Answer:
c) The Diameter is Half of the radius
Step-by-step explanation:
A) A diameter ALWAYS passes through the center of the circle, so EVERY diameter WILL pass through the Center of the circle, making this statement valid.
b) A center of a circle will ALWAYS lie in the interior of the circle. it is an Axiom
c) False, the RADIUS is half of the Diameter of a circle.
d) The Longest Chord IS the Diameter, which passes through the circle, so this statement is valid.
So the false option is (C)
Chloe wants to pay off her credit card debt of $7,316.48 that has an APR of 16.73%. She is paying $300 per month.
a) Using the finance charge defined in class (charge = r*(balance-payments+purchases)), what would be the credit card balance (to the nearest dollar) after one year?
b) If she increased her monthly payment by $50 to $350 per month, what would be the credit card balance (to the nearest dollar) after one year?
a) Using the formula for finance charge, we can find the balance after one year:
charge = r*(balance-payments+purchases)
Here, r = 16.73% = 0.1673 (as a decimal), payments = $300 per month = $3,600 per year, and purchases = 0 (since Chloe is not making any new purchases).
Let's assume that x is the balance after one year. Then, we can write:
0.1673*(7316.48-3600) = x - 3600
Simplifying and solving for x, we get:
x = $6,830.58
So, the credit card balance (to the nearest dollar) after one year would be $6,831.
b) If Chloe increases her monthly payment to $350 per month, then her payments for the year would be $4,200. Using the same formula as above, we can find the balance after one year:
0.1673*(7316.48-4200) = x - 4200
Simplifying and solving for x, we get:
x = $5,774.99
So, the credit card balance (to the nearest dollar) after one year with a $350 monthly payment would be $5,775.
