When dragons on planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 39% of the eggs are yellow, and the rest green. Next spring the lead scientist has permission to randomly select 66 of the dragon eggs to incubate. Consider all the possible samples of 66 dragon eggs. What is the usual number of yellow eggs in samples of 66 eggs

Answers

Answer: The usual number of yellow eggs in the selected sample is 26.

Step-by-step explanation:

It is given that there are 2 types of dragon eggs: Yellow and green

Observation says that 39% of the eggs are yellow.

When selected at random for incubation:

Number of eggs selected are = 66

To evaluate the number of yellow eggs, we must calculate 39% of 66 eggs

[tex]\Rightarrow \frac{39}{100}\times 66\\\\\Rightarrow 25.74\approx 26[/tex]

Hence, the usual number of yellow eggs in the selected sample is 26.

Can someone help me with this question? Workings would be appreciated :] Adrian, Ben and Charlie share some sweets in the ratio 8:5:10 Charlie got 20 more sweets than Adrian. Work out the total amount of sweets.

Answers

Answer: 230 - the total amount of sweets.

Step-by-step explanation:

Adrian received 8 pieces of sweets;

Ben got 5 pieces of sweets;

Charlie received 10 pieces of sweets.

The sum of all parts:

8 + 5 + 10 = 23

Let's calculate how many parts Charlie got more than Adrian:

10 - 8 = 2

It is also known that Charlie received 20 more sweets than Adrian. This means that you can calculate how many sweets are in one part.

20 : 2 = 10

Now we can calculate the total amount of sweets:

10 × 23 = 230

A lamp shade is in form of a frustum of a cone , its upper and lower diameter are 10cm and 20cm respectively , its height is 12cm . Calculate the volume of the frustum

Answers

Answer:

V = 8796.45 [tex]cm^3[/tex]

Step-by-step explanation:

Given data :

A lamp shade is in the form of a frustum of a cone.

The upper diameter of the cone, r = 10 cm

The lower diameter of the cone, R = 20 cm

The height of the frustum, h = 12 cm

Therefore, the volume of the frustum of cone is given by :

[tex]V = \frac{1}{3} \pi H ( R^2 + Rr+r^2)[/tex]

Putting the values, we get

[tex]V = \frac{1}{3} \pi \times 12 [( 20)^2 + (20)(10)+(10)^2][/tex]

[tex]$V=4 \pi[400 + 200+100]$[/tex]

[tex]$V=4 \pi[700]$[/tex]

V = 8796.45 [tex]cm^3[/tex]

Thus the volume of the frustum of cone is V = 8796.45 [tex]cm^3[/tex]

Four rays come together at a single point. What is the value of the missing angle?

Answers

Answer:

? = 140

Step-by-step explanation:

The rays form a circle, which is 360 degrees

90+ 105+25+? = 360

Combine like terms

220+? = 360

? = 360-220

? = 140

Answer:
140 degrees

Explanation:
All of those angles would add up to 360 degrees since it makes up a full circle.
360-105-90-25= 140

steve desposite $1800 per month in his saving bank account. If thi is 20% of the monthly income, find his monthly income​

Answers

Step-by-step explanation:

Hey there!

The amount deposited= $1800

And it's just 20% of total monthly amount.

Let total amount be "x".

Then;

$1800 = 20% of X

[tex]1800 = \frac{20}{100} \times x[/tex]

or, 180000= 20x

or, X = 180000=/20

Therefore, total monthly amount or income was $9000.

What is the distance between point P and point R?

Answers

Answer:

PR = 10

Step-by-step explanation:

PR = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The coordinates for P and R are (0,4) and (-6,-4) respectively.

So you plug in the values:

PR = [tex]\sqrt{(-6-0)^2+(-4-4)^2}[/tex]

PR = [tex]\sqrt{(-6)^2+(-8)^2}[/tex]

PR = [tex]\sqrt{36+64}[/tex]

PR = [tex]\sqrt{100}[/tex]

PR = 10

Answers

Answer:

Combine like terms

Step-by-step explanation:

3x + 6 = 10 + 3x + 4x

Combine like terms

3x + 6 = 10 + 7x

Subtract 3x from each side

3x-3x + 6 = 10 + 7x -3x

6 = 10 +4x

Subtract 10 from each side

6-10 = 10+4x-10

Super Storage takes storage cubes to customers, the customers fill them, and then super storage takes the cubes to their storage warehouse. The volume for one storage cube is 1,041 1/4 cubic feet. If the cubes length is 12 1/4 feet and the width is 8 1/2 feet, how tall is 1 cube.

Answers

Answer:

The height is 10ft

Step-by-step explanation:

Given

[tex]V = 1041\frac{1}{4}ft^3[/tex] --- Volume

[tex]L = 12\frac{1}{4}ft[/tex] --- Length

[tex]W = 8\frac{1}{2}ft[/tex] --- Width

Required

The height (H)

The volume is calculated using:

[tex]V = LWH[/tex]

Make H the subject

[tex]H = \frac{V}{LW}[/tex]

Substitute values for V, L and W

[tex]H = \frac{1041\frac{1}{4}}{12\frac{1}{4}*8\frac{1}{2}}[/tex]

Express as decimals

[tex]H = \frac{1041.25}{12.25*8.5}[/tex]

[tex]H = \frac{1041.25}{104.125}[/tex]

[tex]H = 10[/tex]

The height is 10ft

The area model represents the quotient of 108 ÷ 9. Which equation shown by the area model can be used to find the quotient?

Answers

Solution :

Given that the area model that represents a quotient of 108 ÷ 9.

So, we multiply 9 by multiples of [tex]10[/tex] to [tex]\text{estimate the quotient.}[/tex]

10       20      30       40      

90      180     270     360    

Because 108 is between 90 and 180, the quotient lies between 10 and 20.

Using 10 as the first partial quotient in the area model for 108 ÷ 9,

9 x 10 = 90 ,         so 108 - 90 = 18

Now, 9 x 2 = 18,   so 18 - 18 = 0

10 + 2 = 12

Therefore, the quotient of 108 ÷ 9 is 12.

Answer:  108 ÷ 9 is 12.
