and probably he has a chance of 5 or 4

Step-by-step explanation:

The probability that Allen will select a red marble and the coin will land heads up is 1/10.

To find the probability that Allen will select a red marble and the coin will land heads up, we need to consider two independent events: selecting a red marble and tossing a fair coin.

The probability of selecting a red marble is the number of red marbles (4) divided by the total number of marbles in the box (4 + 8 + 3 + 5 = 20):

Probability of selecting a red marble = 4/20 = 1/5.

The probability of the coin landing heads up is 1/2 since it's a fair coin.

Now, to find the probability of both events occurring together (selecting a red marble and getting heads up), we multiply the probabilities of each event:

Probability of selecting a red marble and getting heads up = (1/5) * (1/2) = 1/10.

So, the probability that Allen will select a red marble and the coin will land heads up is 1/10.

Answer: 13,200 vehicles

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the number of people that will drive to the stadium, by multiplying the total number of fans (80,000) by the percentage in decimal form (57/100).

80,000 x (57/100) = 45,600

Since an average of three fans come in each vehicle, we have to divide the result by 3 to obtain the number of vehicles:

45,600/3 =15,200

Subtract the number of cars that parked in satellite lots.

15,200-2,000 = 13,200 vehicles

Answer: 13,200 rounded up to 13,000.

Step-by-step explanation:

The turnout for a game is expected to reach 80,000 fans, out of which 57% are expected to drive. The number of fans expected to drive will be:

= 57% of 80,000

= 0.57 × 80000

= 45600

An average of three fans come in each vehicle. The number of cars will be:

= 45600 ÷ 3

= 15200 cars

2,000 vehicles park in satellite lots and the rest of the vehicles parked in the stadium lot. Since there are 15200 cars, the number of cars in the stadium lot will be:

= 15,200 - 2,000

= 13, 200

Rounding up 13,200 will give 13,000.

Answer:the width of the rectangle is 9 because sum of the width and one is 9

Answer:

Step-by-step explanation:

No of sample space , n(s) = 12 + 11 + 17 + 5 = 45

No of favorable cases , n(e) = 17

Probability of getting blue marble ,

P(e) = n(e)/n(s)

        = 17 / 45

NOW

Probability of not getting blue marble,

P'(e) = 1 - p(e)

       = 1 - 17 / 45

      = ( 45 - 17)/45

     = 28 / 45

Hope it helped :)

The required probability of not getting blue marble is 28/45.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Given that bag holds 12 red marbles, 11 green marbles, 17 blue marbles, and 5 yellow marbles.

The total number of outcomes. = 12 + 11 + 17 + 5

So n(S) = 45

Number  of favorable outcomes, n(E) = 17

Probability of getting blue marble,

⇒ P(E) = n(E)/n(S)

⇒ P(E) = 17/45

So the required probability of not getting blue marble as

⇒ P'(E) = 1 - P(E)

⇒ P'(E) = 1 - 17 / 45

⇒ P'(E) = (45 - 17)/45

⇒ P'(E) = 28/45

Hence, the required probability of not getting blue marble is 28/45.

Answer: It should be g > 9

Step-by-step explanation:

-Solve:

[tex]g-3>6[/tex]

[tex]g-3+3>6+3[/tex]

[tex]g>9[/tex]

So, Therefore, the result is g > 9

The solution to the inequality is g > 9.

Here, we have,

To solve the inequality g - 3 > 6, we will isolate the variable g.

Adding 3 to both sides of the inequality, we get:

g - 3 + 3 > 6 + 3

Simplifying, we have:

g > 9

So, the solution to the inequality is g > 9.

To graph the solution on a number line, we represent all values of g that are greater than 9. We can denote this by shading the region to the right of 9 on the number line.

Here's a graphical representation:

    ------------------------>

    -8 -7 -6 -5 -4 -3 -2 -1  0  1  2  3  4  5  6  7  8  9 10 11 12 ...

                o

                |

                |

                |

In this representation, the open circle (o) indicates that 9 itself is not included in the solution since the inequality is strict (g > 9). The shaded region represents all values of g that are greater than 9.

Please note that the number line extends indefinitely in both directions, but only the relevant portion is shown here for clarity.

Answer: the distance from one corner of the field to the other corner is 136 m

Step-by-step explanation:

The distance from one corner to the other corner is the diagonal and it

divides the field into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore

d² = 110² + 80²

d² = 12100 + 6400 = 18500

d = √18500

d = 136 meters

The distance from one corner of the football field to the other corner (the diagonal) is approximately 136.08 meters.

To find the distance from one corner of the football field to the other corner (the diagonal), we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the width of the football field is one side of the right triangle, the length of the football field is the other side, and the diagonal (the distance we want to find) is the hypotenuse.

According to the Pythagorean theorem:

[tex]\[ d^2 = w^2 + l^2 \][/tex]

[tex]\[ d^2 = 80^2 + 110^2 \][/tex]

[tex]\[ d^2 = 18500 \][/tex]

To find d, we take the square root of both sides:

[tex]\[ d = \sqrt{18500} \][/tex]

[tex]\[ d \approx 136.08 \][/tex]

Therefore, the distance from one corner of the football field to the other corner (the diagonal) is approximately 136.08 meters.

Answer:

2/75

Step-by-step explanation:

6 of the 30 pens are green, so the probability of selecting a green pen is 6/30 = 1/5.

The pen is then replaced, so there are still 30 pens in the drawer.  4 of the pens are black, so the probability of selecting a black pen is 4/30 = 2/15.

The probability of both events is therefore 1/5 × 2/15 = 2/75.

Answer:

1187.7

Step-by-step explanation:

V = (1/3)πr2h

Volume = 1187.67 cm³.

A cone is a shape formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base. The distance from the vertex of the cone to the base is the height of the cone. The circular base has measured value of radius. And the length of the cone from apex to any point on the circumference of the base is the slant height.

Given,

Height of the cone (h) = 12.7cm

Diameter of the circular base(d) = 18.9cm

Radius (r) = d/2 = 18.9/2 = 9.45cm

Volume of the cone

V = 1/3πr²h

V = 1/3×3.14159×9.45×9.45×12.7

V = 1187.66946

V = 1187.67 cm³

Hence the volume of the cone is 1187.67 cm³.

Answer:

In this instance you would do what is inside the parentheses first and then use the exponent. Therefore it would be 3^2 and your answer is 9.

Step-by-step explanation:

Final answer:

The rule for raising a product to a power does not apply to sums or differences because [tex](5 - 3)^2[/tex] correctly calculated is 4, not 16 as incorrectly applying the rule to the sum would suggest (25 – 9).

Explanation:

The rule that when a product is raised to a power, it is equal to the product of each factor raised to that power, does not apply to sums or differences. The example given is [tex](5 - 3)^2[/tex], if we incorrectly apply the rule to the sum, we might think [tex](5^2 - 3^2)[/tex] which is-

25 – 9 = 16

However, performing the operation correctly, we first do the sum inside the parentheses:

(5 – 3) = 2,

and then raise to the power:

[tex]2^2[/tex] = 4.

This clearly shows that raising a sum to a power is not the same as raising each term to the power and then summing.

Answer:

Pears weight = 1.925 kgs

Step-by-step explanation:

Total weight of apples & pears = 7.7kg

Apples weight = 3/4th of total weight

= ( 3/4 ) x ( 7.7 )

= 5.775

So, remaining pears weight = Total weight - Apples weight

= 7.7 - 5.775

= 1.925

Final answer:

The farmer sold 1.925 kilograms of pears at the farmer's market.

Explanation:

A farmer sells 7.7 kilograms of apples and pears at the farmer's market. To find out how many kilograms of pears were sold, we need to calculate the remainder that is not apples.

Since ¾ of the weight is apples, we have:

Therefore, the farmer sold 1.925 kilograms of pears at the farmer's market.
