Martina read that approximately 10% of all people are left-handed. She wants to design a

simulation to approximate the probability of selecting exactly 2 right-handed people when 3

people are randomly selected.

Part A

In the simulation, Martina has a spinner with sections of equal size. One section is labeled "L"

(left) and the rest of the sections are labeled "R" (right).

For this simulation to be as accurate as possible, what is the total number of

sections that the spinner should have?

Answer:

250Min

Step-by-step explanation:

1st machine = 2520 divided by 180min =14shirts/min

2nd machine =1440 divided by 120min =12 shirts/min

14 shirts/min +12shirts/min =26shirts/min

6500 shirts divided by 26shirts/min =250min

The answer is 250 minutes.

Rounding of decimals refer to the rounding of decimals to certain accuracy. Process of rounding of decimals ; put simply , if the last digit is less than 5, round the previous digit down. However, if it is greater than 5 then round the previous digit up.

Given, The first machine can produce 2,520 shirts in 180 minutes.

So, the first machine is making 2520 / 180 = 14 shirts per minute.

And The second machine can produce 1,440 shirts in 120 minutes.

So, the second machine is making 1440 / 120 = 12 shirts per minute.

If the both machines work together then both are making 14 + 12 = 26 shirts per minute.

To take them to produce 6500 shirts , both will take 6500 / 26 = 250 minutes .

Hence the answer is 250 minutes.

Answer:

C

Step-by-step explanation:

The measure of the inscribed angle DEF is half the measure of its intercepted arc, that is

[tex]\frac{1}{2}[/tex] ∠ DEF = arc ED , that is

arc ED = 2 × 78° = 156°  → C

Option c 156 is correct.

Angle of the arc at tangent EF = 78

Area of circle is given by the pie times square of radius.

Since Angle made by chord with tangent is equal to halve the angle made by cord with its radius.
So

2 ∡DEF = measure of arc ED
= 2 x 78

= 156

Thus, the measure of are ED is 156°

The statement true about the results of the survey is:

Step-by-step explanation:

To identify if the D option is right, you only must use a simple rule of three, where you use the total of the members surveyed in the club (150), and the number of members that preferred the seacoast (72), by the last the operation must confirm that this value (72) is equal to the 48% (how says in the D option). First, you must establish the rule of three:

And operate:

How you can see, the value obtained in the simple rule of three is exactly the percentage of the D option, for this reason, this is the true statement.

Answer:

angle 1 and 3, and angle 2 and 4

Step-by-step explanation:

Answer:

1 and 3 AND 2 and 4

Step-by-step explanation:

Supplementary angles are angles that add up to 180, therefore we can assume that any angles that make a straight line together are supplementary. 1 and 4 do not make a straight line. 2 and 3 do not either. So we have to assume that the answer is either 1 and 3 or 2 and 4. Not sure whether you want one or two answers

Answer:

We have to find the value of cosine for an angle with point ( 5, - 12 ) on its terminating side. First we have to find the hypotenuse ( Adjacent = 5, Opposite = 12 ) : c^2 = 5^2 + 12^2 = 25 + 144 = 169; c = sqrt(169 ), c = 13. Cosine for an angle = Adjacent / Hypotenuse = 5 / 13 = 0.385. Answer: The value of cosine is 5/13, Hope that helps!.

Answer:

the difference would be 28 degrees.

Step-by-step explanation:

The question says difference so we subtract the two following temperatures 30 and -2 which would be 28 degreees.

Answer: The difference between the high and low temperature in the thermometer is 32°F.

Step-by-step explanation:

Given information: Highest temperature = 30°F and the lowest temperature = -2°F.

We need to find the difference between the high and low temperature in the thermometer.

Difference between the high and low temperature is

Difference = Highest temperature - Lowest temperature

Difference = 30°F - (-2°F)

Difference = 30°F + 2°F

Difference = 32°F

Step-by-step explanation:

The opposite side is the side of the triangle facing the given angle. The adjacent side is the side that the given angle and the right angle lies on. The hypotenuse side is the side facing the right angle. (The hypotenuse side usually looks like a slanted line. Do note that this is not true if your adjacent and hypotenuse side is not horizontal and vertical respectively on the plane of your paper.)

I'll explain a bit more below using the some of the questions.

Q1) The given angle here is 27°.

X is facing the given angle hence it is the opposite side.

The side that is 10 units long is the adjacent side as 27° and the right angle sits on it.

tanθ= opp/adj

tan27°= x/ 10

x= 10(tan 27°)

x= 5.1 units (nearest tenth)

Q3) x is the adjacent side, while the side that is 7 units long is the hypotenuse side.

cosθ= adj/hyp

cos39°= x/7

x= 7(cos39°)

x= 5.4 units (nearest tenth)

Q4) x is the hypotenuse and the opposite side is 8 units long.

sinθ= opp/hyp

sin46°= 8/x

x(sin46°)= 8

x= 8/ sin46°

x= 11.1 units (nearest tenth)

Q5) x is facing the given angle, hence it is the opposite side. The adjacent side is given here, which is 6 units long.

tanθ= opp/adj

tan23°= x/6

x= 6(tan 23°)

x= 2.5 units (nearest tenth)

Feel free to ask if you still do not understand any concepts :)

sinθ= opp/hyp

cosθ= adj/hyp

tanθ= opp/adj

2-√3

Step-by-step explanation:

Roots are irrational

Domain: x ≤ 5

Range: y ≤ -3

The square root of a number is an element that can replicate itself to find that number. The square root symbol is \ sqrt {} square root of, end square root. Finding the square root of a number is the opposite of multiplying a number.

The square root of a number is a number that, when multiplied by itself, is equal to the required value. So, for example, the square root of 49 is 7 (7x7 = 49). The process of multiplying a number itself is called squaring.

Mark brianliest if my answer suit your question

Radius of the outer circle = 9cm

Area of a circle = πr²

= π×9×9

= 254.34cm²

Radius of the inner circle = 6cm

Area of a circle = πr²

= π×6×6

Therefore, area of the shaded region = 254.34-113.04
