Answer:

the probability is 1/12

Step-by-step explanation:

The probability, P(Tails) to get tails is equal to:

[tex]P(Tails)=\frac{1}{2}[/tex]

Because a penny have two possible options heads or tails and tails is one option.

Additionally, the probability P(3) that the number cube get a 3 is equal to:

[tex]P(3)=\frac{1}{6}[/tex]

Because the cube have 6 possible options and 3 is one option.

Now, the probability P(tails and 3) is calculated as a multiplication of P(tails) and P(3). then, P(tails and 3) is equal to:

P(tails and 3) [tex]=\frac{1}{2}*\frac{1}{6}=\frac{1}{12}[/tex]

Answer:

1/12

Step-by-step explanation:

First we calculate the probability of the coin tossed being a tails.

The coin has two sides (heads and tails), so the probability of each case is 1/2, so the probabilty of having a tails is 1/2

For the number cube, we have six possibilities, so the probability of having a number 3 is 1/6

Now, to find the final probability P(tails and 3) we just need to multiply both probabilities:

P(tails and 3) = P(tails) * P(3) = (1/2) * (1/6) = 1/12

No because if you are looking for a right triangle its sums have to equal to 90 degrees

Step-by-step explanation:

for example:side a; 30 inches

side B;30 in

c;30 that equals 90 so that is a right triangle

Answer:

No, it is not a right triangle.

Step-by-step explanation:

10.5, 36, and 50 do not form a right triangle.  This can be tested using the Pythagorean theorem.  

10.5^2=110.25

36^2= 1296

50^2=2500

If this was a right triangle, the 10.5 squared and 36 squared would have to equal 50 squared.

Answer: C -1.9

Step-by-step explanation:

The rate of change of this simple index over 1 week given the change in the stock prices is -1.9%.

The rate of change is the difference in the total value of the simple index.

Total value of the simple index at day 1 = (4000 x $3.15) + (5000 x $4.30) + (6000 x $4.60) = $61,700

Total value of the simple index at day 8 = (4000 x $3.50) + (5000 x $3.90) + (6000 x $4.50) = $60,500

Rate of change = (60,500 / 61700) - 1 = -1.9%

Step-by-step explanation:

Answer:

7 birds

Step-by-step explanation:

Let b = number of birds

c = number of cats

We know there were 13 birds and cats

b+c =13

It is $2 per bird and $5 per cat for a total of $44

2b+5c =44

 Solve b+c =13 for c by subtracting b from each side

c = 13-b

Now we can substitute this into the second equation

2b+5c =44

2b + 5(13-b) =44

Now distribute

2b+65 -5b = 44

Combine like terms

-3b +65 =44

Subtract 65 from each side

-3b +65-65 =44-65

-3b = -21

Divide each side by -3

-3b/-3 = -21/-3

b=7

There were 7 birds

We could also find the number of cats

c =13-7

c =6

Answer:

7 birds

Step-by-step explanation:

No. of birds: x

No. of cats: y

2x + 5y = 44

x + y = 13

x = 13 - y

2(13 - y) + 5y = 44

26 - 2y + 5y = 44

3y = 18

y = 6

x = 13 - 6

x = 7

AIRPLANE LIFTING FORCE

Area of Wings   Lifting Force

(square feet)        (pounds)

    125                    1,875

    150                   2,250

    250                  3,750

       x                    5,625

    420                      y

The ratio of lifting force to the area is equivalent for all pairs in the table. What are the values of x and y?

1. Calculate x:

Ratio of lifting force to the area for the first pair (row):

Ratio of lifting force to area for the pair with x:

Set the proportion:

Equal the two ratios

Multiply both sides by 5,625 (multiplication property of equalities):

2. Calculate y:

You can use the same know ratio for the first pair: 125/1,875

And set the corresponding proportion, with y:

Invert both sides:

Multiply both sides by 420

The answer is x = 375 square feet and y = 6,300 pounds.

Final answer:

The quadratic equation 6x2 – 13x – 5 = 0 is solved using the Master Product method by factoring and solving for 'x' to get the solutions x = -1/3 and x = 5/2.

Explanation:

To solve the quadratic equation 6x2 – 13x – 5 = 0 using the Master Product, we'll first look at the coefficients of the quadratic, which are 6, -13, and -5. The Master Product method involves finding two numbers that multiply to the product of the coefficient of x2 (which is 6) and the constant term (which is -5), and add up to the coefficient of x (which is -13). The product of 6 and -5 is -30, and we're looking for two numbers that multiply to -30 and add up to -13.

These numbers are -15 and 2 because (-15) * 2 = -30 and (-15) + 2 = -13. We can use these numbers to split the middle term, -13x, into -15x and 2x, and rewrite the quadratic equation as 6x2 - 15x + 2x - 5 = 0. Grouping the terms in pairs and factoring by grouping gives us (3x)(2x - 5) + 1(2x - 5) = 0. Factoring out the common binomial (2x - 5), we get (3x + 1)(2x - 5) = 0. Setting each factor equal to zero, we can solve for x: 3x + 1 = 0 or 2x - 5 = 0, which gives us x = -1/3 or x = 5/2.

The athlete can cover 4.5 km in 30 minutes. Hence, option C is correct.

Important information:

We need to find the distance covered by the athlete in 30 minutes.

We know that 1 hour = 60 minutes. So,

The distance covered in 60 minutes is 9 km.

The distance covered in 1 minute is [tex]\dfrac{9}{60}[/tex] km.

The distance covered in 30 minutes is [tex]\dfrac{9}{60}\times 30=4.5[/tex] km.

Therefore, the athlete can cover 4.5 km in 30 minutes. Hence, option C is correct.

Step-by-step explanation:

The ratio of the surface areas of the cone shown is 16 : 9.

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given are two cones.

Also given that,

Ratio of the radii of the cones = 4 : 3

It is given that both cones are similar figures.

So scale factor = 4/3

Surface area of a cone = πr² + πr√h²+r²

Now the surface area is proportional to the square of the radii of the cone.

So ratio of surface area = 4² / 3² = 16 / 9

Hence ratio of the surface area of the cones is 16 : 9.

Step-by-step explanation:

Lynn starts with 14.3 gallons in her gas tank.

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

She put 3 7/8 gallons of gas in her gas tank. if there are now 18 1/6 gallons in the tank.

We have to determine the number of gallons did she start with

As per the given question, the required evaluation would be as:

Initial gallons = current gallons - put gallons

Initial gallons = 18 1/6 - 3 7/8

Convert the improper fractions into decimals,

Initial gallons = 18.167 - 3.875

Apply the subtraction operation, and we get

Initial gallons = 14.292 ≈ 14.3

Therefore, she starts with 14.3 gallons in her gas tank.

To estimate the perimeter, we use the given information of the width of the rectangle, which is 1.25 cm. Assuming the lengths are similar, we estimate them to be 1.25 cm as well. Using these measurements, we calculate the perimeter of the figure to be approximately 5 cm.

To estimate the perimeter of the figure, we need to determine the measurements. The given information states that the rectangle is at least 1.0 cm wide but not 2.0 cm wide. Using the tick marks on the ruler, we can estimate the width to be 1.25 cm. Since the perimeter of a rectangle is the sum of all its sides, we find the perimeter by multiplying the width by 2 and adding it to the sum of the two lengths. However, we don't have information about the lengths, so we can't find the exact perimeter, but we can estimate it based on the width. Assuming the lengths are similar, we can use the estimated width of 1.25 cm to estimate the lengths as well.

To estimate the lengths, we can assume that each length is greater than the width. Let's assume the lengths are also 1.25 cm. The perimeter can then be estimated by multiplying the width by 2 and adding it to the sum of the two lengths: (1.25 cm * 2) + (1.25 cm + 1.25 cm) = 2.5 cm + 2.5 cm = 5 cm. Therefore, we estimate the perimeter of the figure to be approximately 5 cm.

The estimated perimeter of the pentagon is 19 units.

To estimate the perimeter of the given pentagon, we need to find the length of each side and add them together. The pentagon has a base of four units and the other sides are three units each.

To find the perimeter, we add the lengths of all the sides. In this case, the base has a length of four units, and there are five sides of three units each.

Calculating the perimeter:
4 + 3 + 3 + 3 + 3 + 3 = 19 units

Therefore, the estimated perimeter of the pentagon is 19 units.
