Answer:

32

Step-by-step explanation:

You just have to find out whats 1/3 of 96

just divided 96 by 3 to get 32

This is an exponential function. Since each year the value of the bike decreases by 5%, each year, the value of the bike is 100%-5%=95% of it's original value. So after x years, the value of the bike would be 200(0.95)^x.

Answer:

(200 - (200 x 5 / 100))^Y

Step-by-step explanation:

As the initial value of the bike is $200, that would be a fixed number in our equation. Each year, this will lose 5% of its value, therefore, it would be another fixed value in it. Then, we have to exponentiate it by the number of years that have passed since the initial value (Y). As a result, the equation to model the situation would be this one:

(200 - (200 x 5 / 100))^Y

When you divide you number actually gets bigger.

Step-by-step explanation:

3/8 and 1/3 can be multiplied by each other in the numerator and denominator: 3/8(3/3) = 9/24 and 1/3(8/8) = 8/24

Answer:

Option B is correct.

Step-by-step explanation:

Confidence interval is the range of the values that the particular probability whose value will lie in the interval.

So, if a level is 0.90 confidence interval it means the value of the probability will lie in the given level.

Therefore, Option B is correct that is an interval computed from sample data by a method that has probability 0.90 of producing an interval containing the true value of parameter of interest.

A 0.90 confidence interval is an interval computed from the sample data, with a probability of 0.90 that it contains the true value of the parameter of interest. The margin of error may vary and is not necessarily ±0.90. No method can absolutely guarantee a 0.90 probability.

A 0.90 confidence interval, in statistical terms, is most accurately defined as an interval computed from sample data by a method that has a probability of 0.90 of producing an interval containing the true value of the parameter of interest. Therefore, the correct answer to this question is option B).

When we say that we're 90% confident, what we're implying is that if we were to repeat the same experiment 100 times, we'd expect the true parameter to lie within the confidence interval 90 times. The margin of error isn't necessarily ±0.90 as suggested by some of the other options (A and C) - it could be any value, depending on the data.

Option D suggests the method guarantees a 0.90 probability. It's crucial to understand that a confidence interval doesn't give such a guarantee; it provides an estimate and there’s always a certain amount of uncertainty.

Answer:

(-4,1)

Step-by-step explanation:

A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Substitution can be used by substituting the value of one variable into the equation.

Pair 2.5x-3y=-13 and 3.25x-y=-14

We can solve for y in 3.25x-y=-14. 3.25x+14=y.

Because y=3.25x+14, we can substitute 3.25x+14 into y in 2.5x-3y=-13.

2.5x-3y=-13

2.5x-3(3.25x+14)=-13

2.5x-9.75x-42=-13

-7.25x-42=-13

-7.25x=29

x= -4

We now substitute x=-4 into y=3.25x+14

y=3.25x+14

y=3.25(-4)+14

y=-13+14

y=1

To solve the system by substitution, solve one equation for one variable and then substitute that expression into the second equation. Solve the resulting equation and then substitute the solution back into one of the original equations to find the other variable.

Given the equations:

Let's find the value of 'x' from the second equation:

y = 3.25x + 14

This formula for 'x' can be substituted into the first equation, resulting in a new equation:

2.5(3.25x + 14) - 3y = -14,

This equation can be simplified and solved to find the variable 'y'. The value of 'y' can then be substituted back into the original equation to find the value of 'x'.

The solution to these two equations, (x, y), is the point of intersection which describes the system of the original equations.

Answer:

Option 2

Step-by-step explanation:

When completing a proof, the statements and reasons should be directly connected. Since the reason listed next to the missing statement is Def of Complimentary Angles, the statement must be about angles adding to 90 degrees. The definition of Complimentary Angles is that two angles add to 90. This means option 2 is the answer.

Answer: 8

Step-by-step explanation:

60 dowels - each 6 inches (1/2 foot) in length = 30 feet of wood

30 feet of wood ÷ 4 foot boards = 7.5 boards

Since he can't buy half of a board, you must round up to 8 boards.

The question involves a conversion of measurements. After converting 4 feet to 48 inches, it's calculated that one piece of wood can produce 8 dowels. To make 60 dowels, you would need 7.5 pieces of wood, but this rounds up to 8 pieces since half a piece cannot be bought.

To answer this question, we first need to understand that all measurements need to be in the same units. Since our dowels are in inches (6 inches long) and our wood lengths are in feet (4 feet long), we need to convert one to the other. For simplicity's sake, let's convert the feet to inches as follows: 1 foot = 12 inches, therefore, 4 feet = 48 inches.

Then, we can find out how many dowels we can get from just one piece of wood: 48 inches / 6 inches per dowel = 8 dowels per one piece of 4-foot wood.

Lastly, to find out how many pieces of wood are needed to make 60 dowels, we divide the total number of dowels by the number of dowels per wood: 60 dowels / 8 dowels per wood = 7.5. Since we can't purchase half a piece of wood, we have to round up, so the carpenter needs to buy a minimum of 8 pieces of 4-foot wood to have enough to make 60 dowels.

Answer:

3250 is your total; p = 50n + 1900 is your equation.

Step-by-step explanation:

"p" represents total pay; "n" represents the number of copies he sells.

Base salary is 1900, and each copy sold gives him an extra 50

p = 50n + 1900 is your equation.

If he sells 27 copies. Plug in 27 for n

p = 50n + 1900

p = 50(27) + 1900

Simplify. Remember to follow PEMDAS. First, multiply, then add.

p = 50(27) + 1900

p = 1350 + 1900

p = 3250

Answer:

x=22, y=48

Step-by-step explanation:

If this is an isosceles triangle, then <G is equal to <J

<g = <j

x+44 = 3x

Subtract x from each side

x+44-x = 3x-x

44= 2x

Divide each side by 2

44/2 = 2x/2

22= x

The three angles of a triangle add to 180 degrees

<G + <J + <H = 180

x+44 + 3x + y = 180

22+44 +66 + y = 180

Combine like terms

132+ y =180

Subtract 132 from each side

132-132+y = 180-132

y = 48

Final answer:

The converse of the statement is "If two angles are equal, then the two angles are both obtuse."

Explanation:

Converse of the Statement:

To write the converse of the statement 'if two angles are both obtuse, the two angles are equal,' we need to swap the hypothesis and the conclusion.

The converse statement would be: 'If two angles are equal, then the angles are both obtuse.'

Example:

Let's consider two angles, Angle A and Angle B. If Angle A and Angle B are both equal, then we can conclude that both angles are obtuse.

Factor theorem: if x-k is a factor of p(x), then p(k) = 0. The same can be said in reverse: if p(k) = 0, then x-k is a factor of p(x).

In this case, x-1 = x-k so k = 1. We'll plug this into f(x) below

f(x) = 14x^99 - 65x^56 + 51

f(1) = 14(1)^99 - 65(1)^56 + 51 ... replace every x with 1

f(1) = 14(1) - 65(1) + 51

f(1) = 14 - 65 + 51

f(1) = -51 + 51

f(1) = 0

The result is 0, so h(x) = (x-1) is a factor of f(x) = 14x^99-65x^56+51

An outlier is something that's way off compared to the rest of the group, basically. Like a person who stands out, but in this case it's a number.

The numbers listed here are all near 40 except 28. So 28 is the outlier, or the 'odd one out.'

Answer:

Step-by-step explanation:

It's solved by grafic method

Set up the equation: 2x+37+3x+y=180 ⇒ 4x+y=143

2x+y+3y-21=180 ⇒2x+4y=201.

Solving for x and y, you get that y=37, thus making x=26.5

Now, for b to be perpendicular to a, 2x+37 must equal 90.

2*26.5+37=90, so b is perpendicular to a.

Whether 'b' is perpendicular to 'a' is determined by their dot product. If the dot product of 'b' and 'a' is zero, then 'b' is perpendicular to 'a'. However, without knowing the specific components of these vectors, a precise computation can't be made.

In mathematics, particularly in vector algebra, vectors are said to be perpendicular or orthogonal if their dot product is zero. This is because the dot product of two vectors encapsulates the angle between them, defined as A·B = |A||B|cos(θ), where θ is the angle. If θ is 90 degrees (indicating the vectors are perpendicular), cos(θ) becomes 0, thus the dot product should be zero.

Therefore, to determine whether 'b' is perpendicular to 'a', we need to compute their dot product. If their dot product equals zero, then we can conclusively say that 'b' is perpendicular to 'a'. Beyond this, you'd need to provide the components of vectors 'a' and 'b' for a specific computation.

Step-by-step explanation:

A rectangle has 90° angles.  So, the diagonal cuts the rectangle into two right triangles where the length (base) and the width (side) are the legs of the right triangle and the diagonal is the hypotenuse. Thus, the Pythagorean Theorem can be used: (leg a)² + (leg b)² = (hypotenuse)²

14² + 6² = hypotenuse²

196 + 36 = hypotenuse²

232 = hypotenuse²

√232 = √hypotenuse²

15.23 = hypotenuse

z1=3 cos (52 + i sin 52)

z2 =3 cos (124 + i sin 124)

z3 = 3 cos (196 + i sin 196)

z4 =3 cos (268 + i sin 268)

z5= 3 cos (340 + i sin 340)

Step-by-step explanation:

To find the fifth roots of 243 (cos 260° + i sin 260°).

z ^ 1/5 = r^1/5 ( cis ( theta + 360 *k)/5)  where k=0,1,2,3,4

So the first root of 243 (cos 260° + i sin 260°)  

is z1 =  243^1/5 ( cis ( 260 + 360 *0)/5)  

          3 cis ( 260/5)

        = 3 cis (52)

        = 3 cos (52 + i sin 52)

The second root of  243 (cos 260° + i sin 260°)  

is z2 =  243^1/5 ( cis ( 260 + 360 *1)/5)  

          3 cis ( 620/5)

        = 3 cis (124)

        = 3 cos (124 + i sin 124)

The third root of  243 (cos 260° + i sin 260°)  

is z3 =  243^1/5 ( cis ( 260 + 360 *2)/5)  

          3 cis ( 980/5)

        = 3 cis (196)

        = 3 cos (196 + i sin 196)

The fourth root of  243 (cos 260° + i sin 260°)  

is z4 =  243^1/5 ( cis ( 260 + 360 *3)/5)  

          3 cis ( 1340/5)

        = 3 cis (268)

        = 3 cos (268 + i sin 268)

The fifth root of  243 (cos 260° + i sin 260°)  

is z5 =  243^1/5 ( cis ( 260 + 360 *4)/5)  

          3 cis ( 1700/5)

        = 3 cis (340)

        = 3 cos (340 + i sin 340)
