A spinner has 2 congruent sectors coloured blue and green. The pointer is spun once, and a coin is tossed.

Find the probability of each event:
a) blue and tails
b) blue or green and heads

Answer: What is the question-? :D

Step-by-step explanation:

Answer:

31/24 or 1 7/24

Step-by-step explanation:

Answer:

D) \(\frac{31}{24}\) or \(1\frac{7}{24}\)

Step-by-step explanation:

Step 1: Convert to numeral form

\(\frac{2}{3}+\frac{5}{8}\)

Step 2: Find a common denominator (multiply denominators then cross-multiply)

\(\frac{16}{24}+\frac{15}{24}\)

Step 3: Add numerators (and leave denominators the same)

\(\frac{31}{24}\) or \(1\frac{7}{24}\)

The properties of the parabola equation are

Vertex = (-5, -4)

Roots = (-7, 0) and (-3, 0)

Points = (-2, 5) and (-4, -3)

What are parabola equations?

Parabola equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

How to plot the graph of the parabola?

The equation is given as

y = x^2 + 10x + 21

Next, we plot the graph on the coordinate plane

On the graph, we can see the following properties

Vertex = (-5, -4)

Roots = (-7, 0) and (-3, 0)

Points = (-2, 5) and (-4, -3)

Answer:

  √689 ≈ 26.2 leagues

Step-by-step explanation:

For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.

The Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...

  c² = a² +b²

Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.

  c = √(a² +b²)

The horizontal distance between the points is the difference of their x-coordinates:

  a = x2 -x1 = 2 -(-18) = 20

The vertical distance between the points is the difference of their y-coordinates:

  b = y2 -y1 = -10 -7 = -17

When we square these numbers, we find their signs to be irrelevant.

  c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689

  c ≈ 26.249

The distance between the given points is about 26.2 leagues.

Answer:

Step-by-step explanation:

1) 4 1/2 x 2/3 (change the 4 1/2 to an improper fraction so it becomes 9/2)

Then it is 9/2 x 2/3 and you multiply across. The answer is 18/6 which is simplified to 3 cups.

2) 2/5 x 2 1/3 -> 2/5 x 7/3 = 14/15

3) 3 1/2 x 1 1/3 -> 7/2 x 4/3 = 28/6 = 4 4/6 = 4 2/3 ft tall

1) 5 / 1/3 When dividing with a fraction, you have to multiply by the reciprocal of the second fraction. So the 1/3 becomes 3/1 and now it is  5 x 3/1 which is 15/1. 15 muffins

2) 1/2 / 4 -> 1/2 x 1/4 = 1/8 of the original package

3) 8 / 1/4 -> 8 x 4/1 = 32/1 = 32 apple pieces

Step-by-step explanation:

Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.

As the tree diagram shows, the number of possible meals is ...

  (possible meats)×(possible fruits)×(possible desserts)

  = 3×2×2 = 12

There are 12 possible lunch options.

Half the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:

  P(no cookie) = 1/2

__

Additional comment

The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

Answer:

Strawberry= 3
Watermelon=3
Coconut=9
Orange=5

Step-by-step explanation:

Quite easy, you can use substitution

First look at the simplest row that can be solved by itself

row 2:

2strawberries +4 = 10

2 strawberries= 6

1 strawberry = 3

Row 3: Strawberry(3)+ orange=8

1 orange= 5

Rpw 4: 14= 1coconut +orange(5)

1 coconut= 9

Row 1: Coconut(9)+ watermelon+ coconut(9)= 21

2 coconut(18)= 21

1 watermelon = 3

========================================================

Explanation:

We have these three rules for scale factors

With those rules in mind, we have enlargements for these transformations.

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

----------------

We also have these reductions

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

----------------

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.

One number is positive, and the other is negative. The numbers are additive inverses. x + y = 0 -----> y = -x

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".
