0²/₃ = 0 but 0⁻²/₃ is undefined because 1/0 is undefined.

Consider 0²/₃. So here, 0 has a positive power though a rational at that.

Any positive powers of 0 is considered as 0 itself. This expression also means that the square of the cubic root of zero. We know that cubic root of 0 is 0 and 0² = 0 itself. So we can conclude that 0²/₃ = 0.

Now consider 0⁻²/₃ .

We have [tex]a^{-b}=\frac{1}{a^b}[/tex].

If a random sample of 49 people is selected from a population and it is found that 12 people in the sample are over six feet tall, then the best point estimate of the proportion of people in the population who are over six feet tall is 0.24

The point estimate is a term used in mathematics to calculate a single value as an approximate of a parameter of a population.

Point estimate can be given the formula:

point estimate = Number of successes / Total number of samples

In this case, the total number of samples = 49

number of people over six feet tall (successes) = 12

Therefore,

proportion of people over six feet tall = 12 / 49

proportion of people over six feet tall = 0.2448

Decimal can be rounded to two decimal places, if the third digit is less than 5, round the second digit down. On the other hand, if the third digit is more than 5, round the second digit up.

Therefore,

proportion of people over six feet tall = 0.2448 = 0.24

Thus the point estimate of the proportion of people in the population who are over 6 feet tall is calculated to be 0.24

For instance, when a coin is tossed into the air, a Head or Tail are two possible results.

Hence, the term "probability" is most commonly used to refer to the likelihood that a specific event (or group of events) will occur, either as a linear scale from 0 (impossibility) to 1 (certainty) or as a percentage between 0 and 100%. Statistics is the study of events subject to probability.

Answer:

m<1=75 degree m<2=105degree

m<3=75 degree m<4=105 degree

Answer:

m∠1 = 75°

m∠2 = 105°

m∠3 = 75°

m∠4 = 105°

Step-by-step explanation:

Angles on a straight line sum to 180°

⇒ m∠1 + m∠2 = 180°

Given:

⇒ m∠2 - m∠1 + m∠1 = 30° + m∠1

⇒ m∠2 = 30° + m∠1

Substitute the found expression for m∠2 into the first equation and solve for m∠1:

⇒ m∠1 + m∠2 = 180°

⇒ m∠1 + 30° + m∠1 = 180°

⇒ m∠1 + 30° + m∠1  - 30° = 180° - 30°

⇒ m∠1 + m∠1 = 150°

⇒ m∠1 = 150° ÷ 2

⇒ m∠1 = 75°

As angles on a straight line sum to 180°, subtract m∠1 from 180° to find m∠2:

⇒ m∠2 = 180° - m∠1

⇒ m∠2 = 180° - 75°

⇒ m∠2 = 105°

Vertical Angles Theorem:  When two straight lines intersect, the opposite vertical angles are the same (congruent).

⇒ m∠3 = m∠1 = 75°

⇒ m∠4 = m∠2 = 105°

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

let say they will meet after time t.

distance covered by first boat = velocity of boat × time= 8.5t

distance covered by second boat= 5.5t

distance between both boats = 35km.

There are two possibilities: (i) Perpendicular line: y = 2 · x + 6, Parallel lines: y = - (1 / 2) · x + 7 / 2, y = - (1 / 2) · x + 6, (ii) Perpendicular line: y = - 2 · x + 6, Parallel lines: y = (1 / 2) · x + 7 / 2, y = (1 / 2) · x + 6.

The missing coordinate of one of the points of intersection can be found by using the least distance between the two parallel lines and the Pythagorean theorem:

(a - 0)² + (4 - 6)² = 5

a² + (- 2)² = 5

a² + 4 = 5

a² = 1

a = ± 1

There are two possibilities: (x₁, y₁) = (- 1, 4), (x₂, y₂) = (1, 4). Now we proceed to find the equations associated to each case:

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

From the graph, the function has four different definitions, in intervals, A, B, C and D.

From the axis of the graph, we have that:

The velocity is given by distance divided by time, hence:

30/4 = 7.5.

4. The person traveled at a rate of 7.5 miles per hour in Section A.

In Section B, the person remains at the same position, hence:

5. In section B, the person remained stopped 30 miles from her starting point for 2 hours.

The distance was of 0, hence:

6. The velocity for Section B was of 0 miles per hour.

In Section C, from the y-axis of the graph, the distance traveled was:

60 - 30 = 30 miles.

7. The person traveled 30 miles in Section C.

For Section D, the person traveled 60 miles in 10 - 7 = 3 hours, hence:

8. The speed in Section D was of 20 miles per hour.

10. The farthest distance traveled was of 60 miles in Section D.

In Section C, the person traveled 30 miles in one hour = 30 miles per hour, hence:

9. The person was moving at the highest speed in Section C, at a rate of 30 miles per hour.

Her parents charged 5% simple interest and the credit union charged 6% simple interest.We are asked to calculate how much did she borrow from her parents, and how much did she borrow from the credit union, if after 1 year, she paid $255 in interest.We assume that Amanda borrows $x from her parents.Then we know that she would have borrowed $(5000 - x) from the credit union as the total borrowed amount was $5000.We know that the simple interest (S.I.) on $P, at the rate of r%, for a period of t years, is calculated as S.I. = Prt/100.Thus, for the amount she borrowed from her parents, the simple interest is, S.I. = (x)(5)(1)/100 = x/20.For the amount she borrowed from the credit union, the simple interest is,S.I. = (5000 - x)(6)(1)/100 = (30000 - 6x)/100 = 300 - 3x/50.Thus, the total interest Amanda needs to pay is x/20 + 300 - 3x/50 = 300 - x/100.But, we are given that the total interest Amanda pays is $255.Thus, we can write that 255 = 300 - x/100,or, x/100 = 300 - 255,or, x/100 = 45,or, x = 4500.Thus, the amount Amanda borrows from her parents = $4500.The amount she borrows from the credit union is $(5000 - 4500) = $500.Thus, Using simple interests, we can say that:Amanda borrowed $4500 from her parents.Amanda borrowed $500 from the credit union.

Answer: ∠1 = 109°    ∠2 = 71°

Step-by-step explanation:

If the two angles form a linear pair, then their sum is 180°

 ∠1      +     ∠2     = 180°

(5x + 9) + (3x + 11) = 180

             8x + 20  = 180

             8x          = 160

               x          = 20

∠1 = 5x + 9

   = 5(20) + 9

   = 100   + 9

   = 109

∠2 = 3x + 11

    = 3(20) + 11
