Answer:

Angle of elevation of sun = 59°

Step-by-step explanation:

Given:

Height of tree = 20 feet

Shadow of tree on ground = 12 feet

Find:

Angle of elevation of sun

Computation:

Height of tree = Perpendicular

Shadow of tree on ground = Base

Using trigonometry function;

Tanθ = Perpendicular / Base

Tanθ = 20 / 12

Tanθ = 1.66

Tanθ = Tan 59°

θ = 59°

So,

Angle of elevation of sun = 59°

Answer:

Perimeter = 2 ( l + w )

if u r given for rectangle thats the formula

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

Answer:

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of circular hot tube = 89 inches

Value of π = 3.14

Find:

Area required for circular hot tube

Computation:

Radius of hot tube = Diameter / 2

Radius of hot tube = 89 / 2 inches

Area required for circular hot tube = Area of circle

Area of circle = πr²

Area required for circular hot tube = πr²

Area required for circular hot tube = (3.14)(89/2)²

Area required for circular hot tube = (3.14)(7921 / 4)

Area required for circular hot tube = (3.14)(1,980.25)

Area required for circular hot tube = 6,217.985

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Here is the complete question

here are 2 yellow, 3 green, 1 orange, and 4 red cards in a stack of cards turned facedown. Once a card is selected, it is not replaced. Find each probability.

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

1. P(two yellow cards)

there are a total of 10 cards and 2 yellows cards. If 1 yellow card is picked, it would remain 1 yellow card and 9 cards

P(two yellow cards) = 2/10 x 1/9 = 1/45

Answer:

The required height is equal to 5.33 feet.

Step-by-step explanation:

Given that,

Diameter, d = 10 feet

Volume, V = 419 ft.³

We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.

The tepee is in the form of a  cylinder. The volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]

So, the required height is equal to 5.33 feet.

Answer:

well wouldnt there be a 50/50 chance her choice will be picked since there are only 2 im sorry if im wrong

Step-by-step explanation:

Probabilities are used to determine the chances of an event.

The probability that Bella’s two choices will be picked is 1/231

The parameters are given as:

[tex]\mathbf{n = 22}[/tex] -- number of students

[tex]\mathbf{r = 2}[/tex] --- Bella's selection.

Each student in the class have an equal chance.

So, the probability of selecting a student is:

[tex]\mathbf{Pr = \frac 1{22}}[/tex]

The probability that Bella's two choices are picked is:

[tex]\mathbf{Pr = P(First\ and\ Second)\ or\ P(Second\ and\ First)}[/tex]

So, we have:

[tex]\mathbf{Pr = \frac{1}{22} \times \frac{1}{22 - 1} + \frac{1}{22} \times \frac{1}{22 -1}}[/tex]

NB: 1 is subtracted, because no students can be selected more than once

So, we have:

[tex]\mathbf{Pr = \frac{1}{22} \times \frac{1}{21} + \frac{1}{22} \times \frac{1}{21}}[/tex]

[tex]\mathbf{Pr = \frac{1}{462} + \frac{1}{462}}[/tex]

Take LCM

[tex]\mathbf{Pr = \frac{1 +1}{462}}[/tex]

[tex]\mathbf{Pr = \frac{2}{462}}[/tex]

Simplify

[tex]\mathbf{Pr = \frac{1}{231}}[/tex]

Hence, the probability that Bella’s two choices will be picked is 1/231

Answer: If I put a line over the number that means continued Ex: (23.333333..., 3.098888 or 56.77777...)

11. Mean 1 + 2 + 3+ 3+ 4+ 4+ 4+ 5+ 5 / 9 = 31/9 =26.5 .Median 4 Mode 4 Range 5 - 1 = 4. _

12. Mean 6.5 + 7.5 + 7.5 + 7.5+ 8 + 8.5 + 8.5 + 8.5 + 8.5 + 8.5 +9 = 88.5/11 =8.045

median 8.5 mode 8.5 range 9 - 6.5= 2.5

13. Mean 5.75 + 7.25 + 7.75 + 8 = 28.75/4 = 7.1875. median 7.25 + 7.75 = 15/2 = 7.5 range 8 - 5.75 = 2.25

18. 1 + 2 + 2 + 2 + 2+ 2 + 2 + 2 + 4 + 4 + 5 = 27/11 = 2.45 median 2 mode 2 range 4.

Step-by-step explanation:

Mean

Add up all the numbers, then divide by how many numbers there are. Ex: 2, 3, 4. 2 + 3 + 4 = 9. Since there is 3 numbers we divide. 9 divided by 3 equals 3 so 3 is your mean.

Median

Arrange your numbers from least to greatest.

Count how your numbers.

If you have a set of odd numbers, the number in the middle is your median. Ex: 2, 3, 6, 7, 1, . your median is 6.

Mean

If you have a set of even numbers use the 2 numbers in the middle then divide. Ex: 1, 5, 3, 8, 9, 2. The two numbers in the middle are 3 and 8 . 3 plus 8 equals 11. 11 divided by 2 is 5.5. the mean.

Mode

write the numbers from least to greatest. The number that shows the most is your mode. Ex. 4 , 6 ,7 ,3 ,1 3, 3, 3, 2 3, . The number that appears the most is 3. So 3 is the mode. If there is no number that appears more than all the others put NONE or N/A in the blank.

Range

To find the range put the subtract the greatest number and least number. Ex: 2, 4, 7, 1, 8. 1 , 2, 4, 7, 8. 8 mins 1 is 7 so 7 is the range.

Answer:

b it has a difference when subtracting

Answer:

The answer is B.

Step-by-step explanation:

When you subtract you get a difference.

Given:

The temperature of the first 6 days in march is:

23F, 58F, 62F, 64F, 64F, 65F

23 F is removed from the data set.

To find:

How much greater is the range of the original 6 temperatures than the range of the 5 temperatures.

Solution:

Range of a data set is:

Range = Maximum value - Minimum value

The given data set is:

23 F, 58 F, 62 F, 64 F, 64 F, 65 F

The range of given data set is:

Range = 65 - 23

           = 42

If the temperature 23 F is removed from the data set, then the new data set is:

58 F, 62 F, 64 F, 64 F, 65 F

The range of this new data set is:

Range = 65 - 58

           = 7

Now, the difference between original range and new range is:

[tex]42-7=35[/tex]

The original range is 35 more than the new range. Therefore, the correct option is a.

Answer:

B.11+7=18

Step-by-step explanation:

its B because since its 7 days AFTER it means your going to have to add the 11 days plus this 7 days. Which would give you 18 days left till Susie's concert.
