Suppose that you and a friend are playing cards and decide to make a bet. If you draw three red cards in succession from a standard deck of 52 cards with replacement, you win $30. Otherwise, you pay your friend $20. If the same bet was made 30 times, how much would you expect to win or lose? Round your answer to the nearest cent, if necessary.

Using the Zero Factor Property, solve (2x + 1)(x - 6) = 0.

Answers

Answer:

1 2/3 or 1.67

Step-by-step explanation:

(2x+1)+(x-6)=0

Remove parenthesis.

2x+1+x-6=0

Rearrange to make life temporarily easier.

2x+x+1-6=0

Now combine like terms.

3x-5=0

Add 5 to cancel it out.

3x-5=0

   +5 +5

3x=5

Divide 3 from both sides to cancel that out.

3x=5

/3  /3

x=5/3 or 1 2/3

So the answer is 1 2/3 or 1.67

Answer:

1,296 students attended the fall play.

Step-by-step explanation:

Let the amount of students = s

Let the amount of adults = a

Three times the adults: 3a

150 fewer than three times the adults:3a-150

amount of students = 150 fewer than three times the adults: s=3a-150

We also know that a+s=1778. Let's sub in the value for s that we got above:

a+s=1778

a+3a-150=1778

4a=1928

a=482

a+s=1778

482+s=1778

s=1296

A glass prism on a chandelier is 80 millimeters long. A base of the prism is an equilateral triangle with side lengths of 9 millimeters and a height of about 5.8 millimeters. What is the approximate surface area of the prism?

Answers

Let's find the area of the equilateral triangle first:

There are two triangles - one on each end. So we multiply our previous expression by 2.

Each rectangle is 75 millimeters long and 9 millimeters wide: 75*9 mm^2.

We have 3 rectangles each the same size so we multiply 75*9 by 3.

75*9*3 = 2025

2025 + 70.2 = 2095.2

when can a parallelogram also be a kite?

Answers

Answer:

  when it is a rhombus

Step-by-step explanation:

A kite is a figure in which the diagonals are perpendicular, and one of them is bisected by the other. It will be a parallelogram if both diagonals bisect each other. Such a figure (with mutually perpendicular bisectors as diagonals) is a rhombus.

A parallelogram that is a rhombus will also be a kite.

The logging company would like to use its sample to provide convincing statistical evidence that over 50 percent of the trees in the forest are spruce trees. The logging company has decided to use a chi-square goodness-of-fit test to justify its claim. Why is the chi-square goodness-of-fit test not an appropriate procedure for the logging company to use

Answers

Answer:

The chi-square goodness-of-fit test is best used with categorical variables.  The trees in the forest are not categorical variables but numerical.

Step-by-step explanation:

The chi-square goodness-of-fit test determines whether the distribution of cases in a single categorical variable follows a known distribution.  The chi-square goodness-of-fit test data deal with data frequencies, levels, or counts of cases rather than percentages or other data transformations. Lastly, the categories of the variables are mutually exclusive because they assume the form of either or.

Answer:

A chi-square goodness-of-fit test would be used to show that the entire distribution of trees in the forest is different than what the forester reported, not necessarily the individual proportion representing the spruce trees.

The average temperature for four days was 22°. What must the temperature be on the fifth day in order to make 23° the temperature for the five days?​

Answers

Answer:

27°C

Step-by-step explanation:

Average temperature on 4 days

[tex] = \frac{total \: temperatures \: for \: 4 \: days}{4} [/tex]

Total temperatures for 4 days

= 4(22)

= 88

If the average temperature throughout 5 days is 23°,

total temperature for 5 days

= 5(23)

= 115

Temperature on the 5th day

= total temperatures for 5 days -total temperature for 4 days

= 115 -88

= 27°C

2.1.1 Taxable income.
2.1.2 Tax rebates.
2.1.3 Tax threshold.​

Answers

Answer:

Taxable income:

Taxable income includes wages, salaries, bonuses, and tips, as well as investment income and various types of unearned income. ... Taxable income also includes earnings generated from appreciated assets that have been sold during the year and from dividends and interest income.

Tax rebates:

A tax rebate (or tax refund) is money you reclaim from HMRC if you've paid too much tax. Travel tax refunds are a great example. If you're paying your own way to get to temporary workplaces, you can claim back some tax on your travel expenses.

Tax threshold:

The tax threshold is the amount of income below which you do not pay any income tax. The filing threshold is the income amount below which you do not have to file a tax return to Sars.

The skating rink charges $0.75 to rent skates and $1.25 per hour to skate. Which equation

$4.50?

a) 0.75 + 1.25 = 4.50
b) h(0.75 + 1.25) = 4.50
c) 0.75 + 1.25h = 4.50
d) 0.75h + 1.25 = 4.50

Answers

Answer:

C.

It can be read as...

".75 was charged for skates, and 1.25 was charged per hour for a total of 4.50."

No other answer choice has this. A does not have the variable h, B includes .75 which is NOT charged per hour, as well as D.

given the circumference of circle b is 85 ft . what is the arc lenght of arc ADC?and the lenght of arc Ac​

Answers

Answer:

Length of arc AC = 10.6 ft

Length of arc ADC = 73.4 ft

Step-by-step explanation:

θ = 45°

Circumference = 85 ft

✔️First, find the radius:

Circumference of a circle = 2πr

Thus:

85 = 2πr

Solve for r

Use 3.14 as π

Divide both sides by 2π

85/2π = r

85/2*3.14 = r

85/6.28 = r

r = 13.5350318 ≈ 13.5 ft (nearest tenth)

✔️Find length of arc ADC:

Length of arc = θ/360 × Circumference of the circle

θ = 360 - 45° = 315°

Circumference = 85 ft

Plug in the values

Length of arc ADC = 315/360 × 85

= 74.375 ≈ 73.4 ft (nearest tenth)

✔️Find length of arc AD:

Length of arc = θ/360 × Circumference of the circle

θ = 45°

Circumference = 85 ft

Plug in the values

Length of arc AC = 45/360 × 85

= 10.625 ≈ 10.6 ft (nearest tenth)
