Find the probability of choosing 3 blue marbles in a row if the marbles are replaced

Answer:

90

Step-by-step explanation:

A semicircle is 1/2 of a circle

A circle is 360 degrees

1/2 is 180

We have 90 degrees already used on the left

180-90 = 90

b = 90 degrees

Answer:

90

Step-by-step explanation:

The whole thing equals 360

so have equals 180

and half of one 180 is 90 and you're trying to find that half of 180.

The median of the afternoon (PM) group is 23.

To find the median of a set of numbers, we need to arrange them in ascending order and find the middle value.

Arranging the numbers in ascending order:

7, 9, 10, 12, 13, 15, 15, 16, 21, 23, 25, 26, 28, 30, 35, 35, 37, 38, 44, 55

There are 20 numbers in the dataset, so the middle value would be the 10th number when arranged in ascending order. In this case, the median of the afternoon (PM) group is 23.

Therefore, the median of the afternoon (PM) group is 23.

Answer:

56.52 but you have to round so its 57

Step-by-step explanation:

You have to multiply 18 and pi so we will use 3.14 for pi. 18 times 3.14 will give you 56.52 but you have to round it so it will be 57. If the number is greater than 5 you round up but if it is less you round down.

Square root 114 represents the point p.

Given,

The point P value in the given figure is between 10 and 11.

We need to find which value in the option is represented by point P.

Given options are :

Sqrt 11 = 3.31

Sqrt 21 = 4.58

Sqrt 114 = 10.67

Sqrt 121 = 11

We need to see which option gives a value between 10 and 11.

We have,

Sqrt 114 = 10.67.

We also know that point P lies between 10 and 11.

Sqrt 114 gives a value between 10 and 11.

Thus Sqrt 114 represents the point p.

Step-by-step explanation:

If we were to draw a horizontal line from the bottom of the ladder to the bottom of the tree and then draw a vertical line from the bottom of the tree to the top of the ladder, we'd get a right triangle with legs as the distance between the bottom of the tree and the bottom of the ladder and the height of the ladder, and the hypotenuse is the length.

Here, we know the hypotenuse is 10 feet and that the bottom of the ladder is 4 feet away from the bottom of the tree, so use the Pythagorean Theorem to find the height:

h = [tex]\sqrt{10^2-4^2} =\sqrt{84}[/tex] ≈ 9.2 feet

The answer is C.

Answer:

9.2 feet

Step-by-step explanation:

The ladder forms a right angle triangle with the ground and the tree

10² = 4² + h²

h² = 100 - 16

h² = 84

h = 9.16515139

Answer: 3.61km or √13

Step-by-step explanation:

Given Data:

Sides of hexagon = 2km each

Distance walked by Ama = 5km

Therefore;

Let Ama starting position be the origin.

With this She would travel along two edges and then go halfway along a third.

Her new x- coordinate would be

= 1 + 2 + 1/2 = 7/2

Because she travels a distance of 5km which translates to 2 and half side of the Hexagon

= 2*1/2

= 1km. On her x-coordinates

For her y-coordinate we use same principles as x-coordinates

= √3 + 0 - √3/2

= √3/2

Therefore her distance walked

= √ ( (7/2)^2 + (√ 3/2)^2 )

= √ ( 49/4 + 3/4 )

= √ 13

= 3.61km

Step-by-step explanation:

0.05 x 365 = 18.35

18.25 x 3 = 54.75

Answer:

54.75

Step-by-step explanation:

To find this answer we will first take our 3 years and turn them into days instead.

There are 365 days in a year, so, 365 x 3 = 1095 days

Next, take the 1095 days and multiply it by the number she is saving everyday

1095 x .05 = 54.75

Nicole will have saved 54.75 in three years.

The probability of drawing three green marbles consecutively without replacement from a bag containing different colored marbles is approximately 0.018 when calculated step by step.

The question is about calculating the probability of drawing three green marbles in a row from a bag that contains multiple colored marbles. To find this probability, we need to use the concept of probability without replacement.

First, calculate the probability of drawing one green marble. There are 5 green marbles out of a total of 16 (7 red + 4 blue + 5 green), so the probability is 5/16. When we draw a green marble, we do not replace it, so there are now 4 green marbles left out of 15 total marbles. The probability for the second draw is then 4/15. Lastly, for the third draw, there are 3 green marbles out of 14, making the probability 3/14.

To find the overall probability of all three events occurring, calculate the product of the individual probabilities: (5/16) * (4/15) * (3/14). This gives us 60/3360, which simplifies to 1/56. To the nearest thousandth, that is approximately 0.018.

So the probability that all three marbles drawn will be green, to the nearest thousandth, is 0.018.

hope this helps

To calculate the percentage decrease from 47 to 44, the difference is divided by the original number and then multiplied by 100. The result is approximately a 6.4% decrease.

To calculate the percentage decrease of the number from 47 to 44, we use the following formula for percentage decrease:

Percentage decrease = ((Original Value - New Value) / Original Value) × 100%

In this case, the original value is 47 and the new value is 44. So the calculation would be:

Percentage decrease = ((47 - 44) / 47) × 100%

Percentage decrease = (3 / 47) × 100%

Percentage decrease = 0.0638 × 100%

Percentage decrease = 6.38%

To give the answer to the nearest tenth of a percent, we round 6.38% to 6.4%. So, the number 47 is decreased by about 6.4% to become 44.

Based on the graph, the domain of the function [tex]y=3\sqrt{x}[/tex] is [0, ∞].

In Mathematics and Euclidean Geometry, a domain is the set of all real numbers (x-values) for which a particular relation or function is defined.

The horizontal section of any graph is typically used for the representation of all domain values. Additionally, all domain values are both read and written by starting from smaller numerical values to larger numerical values, which means from the left of a graph to the right of the coordinate axis.

By critically observing the graph shown in the image attached below, we can logically deduce the following domain:

Domain = [0, ∞], {x|x ≥ 0}.

To find the height of the fourth bar in a relative frequency histogram, calculate the total frequency, subtract the sum of the first three frequencies, and divide the remaining frequency by the total frequency.

The relative frequency histogram given has four classes. The heights of the first three bars are 0.25, 0.35, and 0.1 respectively. To find the height of the fourth bar, we need to calculate the total frequency first. Then, subtract the sum of the first three frequencies from the total frequency. Finally, divide the remaining frequency by the total frequency to get the height of the fourth bar.
