Answer:
The answer is 16.3
Step-by-step explanation:
For a random distribution with an specific mean and standard deviation, the most probable values are the ones that lie between the ( means + or - standard deviation)
so in this case, the confidence range is:
Low = 15.5-1.5= 14
High = 15.5+1.5= 17
Values that lie between this range are more probable. So in this case 16.3, which is the only value in this range, has higher chance of occuring.

Suppose that in a certain triangle, the degree measures of the exterior angles are in the ratio 2:3:4. If the largest interior angle measures y degrees, what is the value of y?
Final answer:
To find the largest interior angle y in a triangle with exterior angles in the ratio 2:3:4, we use the fact that the sum of a triangle's exterior angles is 360° to find the value of each exterior angle, then deduce y as the supplement of the largest exterior angle, resulting in y being 20°.
Explanation:
To find the value of the largest interior angle y in a triangle where the exterior angles are in the ratio 2:3:4, we start by understanding that the sum of the exterior angles of any triangle is 360°.
This means that the exterior angles in this triangle are 2x, 3x, and 4x degrees, respectively, where x is a common multiple.
Given that the sum of these angles must be 360°, we can write the equation 2x + 3x + 4x = 360°, simplifying to 9x = 360° and solving for x gives us x = 40°.
The largest exterior angle is 4x, which equals 160°. Since the exterior angle is supplementary to the interior angle it shares a vertex with, the largest interior angle y is therefore 180° - 160° = 20°.
Thus, the value of y is 20°.

Sue’s Corner Market has a markup of 60% on bottled water. If the market sells a bottle of water for $2, find the original amount that Sue pays.
Markup is the amount added to the cost price of goods to cover overhead and profit.
Sue’s Corner Market has a markup of 60% on bottled water.
Let us say original price was $x.
Now price after markup is $2.
So we can make an equation like:
original price + markup price = price after markup
x + 60% of x =2
[tex] x + 0.6x =2 [/tex]
[tex] 1.6x =2 [/tex]
dividing both sides by 1.6
x= 1.25
So original price was 1.25 dollars.
Answer:
1.25 dollars.

Write three functions. In the first function, y should vary directly with x. In the second function, y should vary inversely with x. In the third function, the relationship between x and y should be neither inverse variation nor direct variation.
1) y = kx . . . . . for some constant k
.. Here y is directly proportional to x , where k is the constant of proportionality
2) y = k/x . . . . for some constant k
.. Here y is inversely proportional to x , again k is the constant of proportionality.
3) y = 2x +52
..
Here y is linearly related to the x , it is neither directly proportional nor inversely proportional.

To simplify the given expression we apply exponential property.
Multiply the outside exponent with inside exponent
[tex](a^m)^n= a^{mn}[/tex]
when we multiply the outside exponent -2 inside 9 , it becomes -18
So the given expression becomes

Derek wrote the following paragraph proof for the Vertical Angles Theorem:
The sum of angle 1 and angle 4 and the sum of angle 3 and angle 4 are each equal to 180 degrees by the definition of supplementary angles. The sum of angle 1 and angle 4 is equal to the sum of angle 3 and angle 4 by the transitive property of equality. Angle 1 is equal to angle 3 _____________________.
Which phrase completes the proof?
by construction using a straightedge
by the definition of a perpendicular bisector
by the subtraction property of equality
by the vertical angles theorem

If quadrilateral ABCD rotates 90° counterclockwise about the origin, what are the coordinates of A′ in quadrilateral A′B′C′D′ ?
(2, 1)
(-2, -1)
(-2, -2)
(-2, 0)
I believe the answer is (-2,-1) after the original point (2,1) goes through the change of -y,x
Answer:
Option B is correct.
The coordinate of A' is (-2 , -1)
Explanation:
The coordinates of ABCD are A = (-1,2) , B(1,1) , C =(1,-1) and D(-2,-2).
Rotation means moving the shape around a fixed point clockwise or anticlockwise, and by a certain number of degrees.
Rule for 90° counterclockwise rotation about the origin: [tex](x,y) \rightarrow (-y,x)[/tex]
or we can say that switch x and y in the coordinates and make y value opposite.
Then, the coordinate of A' :
[tex]A(-1,2) \rightarrow A'(-2 ,-1) [/tex]
Therefore, the coordinate of A' in the quadrilateral A'B'C'D' is, (-2 ,-1)
frank purchased a boat for $7,525. he made a down payment of $475. he applied for a six year installment loan with an interest rate of 8.4% in the amount of $7,050. what is the total cost of the boat after six years?
Answer:
$9474.40
Step-by-step explanation:
A spreadsheet can be used to calculate the amortization of the loan. The one attached uses rounding to the penny for all dollar amounts. The result is that the payment amount is rounded down, and the final payment is about 12¢ short. The total repaid on the loan will be slightly more than the product of payment amount ($124.99) and number of payments (72).
The total cost of the boat is the sum of down payment, loan amount, and interest amount. That sum is $9474.40.
A right triangle has a leg of 13 cm and a hypotenuse of 21 cm. What is the length of the other leg? Round to the nearest tenth
A. 8.0 cm
B.16.5 cm
C. 24.7 cm
D. 272.0 cm
The other leg of the right triangle will be 16.5cm.
Legs of a right triangle:The side which shares the common/neighboring border to the right angle in a triangle is called legs.
Pythagoras theorem:It states that the sum of the areas of the two squares on the legs equals the area of the of the square on the hypotenuse.
According to the given question, we have
length of one leg of the right triangle is 13cm.
hypotenuse of the right triangle is 21 cm .
Let x be the length of the other leg.
Now, according to the Pythagoras theorem
We can write as
[tex](21)^{2} = x^{2} +(13)^{2}[/tex]
⇒ 441 = [tex]x^{2} +169[/tex]
⇒[tex]441-169 =x^{2}[/tex]
⇒ [tex]272 =x^{2}[/tex]
⇒ [tex]x = \sqrt{272}[/tex]
⇒[tex]x = 16.49[/tex] ≈ 16.5cm
Hence, the other leg of the right triangle will be 16.5cm.
