An earthworm farmer set up several containers of a certain species of earthworms so that he could learn about their lengths. The lengths of the earthworms provide information about their ages. The farmer measured the lengths of 25 earthworms in one of the containers. Each length was measured in millimeters.
Here are the lengths, in millimeters, of the 25 earthworms.

Answer:

14.43 years

Step-by-step explanation:

FV = PV (1+i)^n            

    FV = future value = 15100     PV = present value = 6000

     i = period interest in decimal  = .065/2 = =.0325

     n = periods = the question

15100 = 6000(1+.0325)^n

solve for n = 28.86 periods     or  14.43 years    (each period is 6 mos)

Answer:

Step-by-step explanation:

wow,  they really try to make these probablity questions difficult.  so they say 5 but really,  b/c the 1st one is heads ,  we are tossing the coin 4 more times, to find 3 heads b/c we already got one.    wow,  I'm mad at the teacher that asked this.  :P   Just say 4 flips for 3 heads.

P(H) = heads

P(H) =1/[tex]2^{4}[/tex]   probability is 1/[tex]2^{4}[/tex] because we have two outcomes and four tries.

P(H) = 1/16

P(H>=3)  3 * 1/16

P(H>=3) = 3/16

if there is an argument that you have to take 1/[tex]2^{5}[/tex] into account by the teacher tell them that it was already resolved ,  the first flip is not a "probablity" any longer.  It's heads,  100%  ,  it doesn't affect the next tosses b/c this is a "fair" coin and it's going to land on heads  50% of the time, for every toss.   Just my rant.  :P

Step-by-step explanation:

A percentage is a way to describe a part of a whole. The percentage decrease will be 20%.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The percentage change is calculated as,

Percentage Change= (Initial Value - Final value)/Initial Value × 100%

Given initially the mass is 80kg, while the final mass is 64 kg, therefore, the percentage change can be calculated as,

Percentage change = (80-64)/80 × 100% = 20%

Hence, the percentage decrease will be 20%.

Answer: 432

Step-by-step explanation:

The formula for the area of a triangle:

[tex]A=[/tex] [tex]\frac{H*B}{2}[/tex]

Substitute area and base:

[tex]1296 = \frac{H*6}{2}[/tex]

Multiply by the denominator to eliminate the fraction:

[tex]2*1296 = \frac{H*6}{2} *2\\[/tex]

The area of a 2D form is the amount of space within its perimeter. The area of the right triangular prism is 1,200 m².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the triangular prism can be written as,

Total surface Area

= Area of two rectangle face + Area of two triangular face + Area of base

= 2(17×15) + 2(0.5×30×8) + (30×15)

= 2(255 in²) + 2(120 in²) + 450 in²

= 1,200 in²

Hence, the area of the right triangular prism is 1,200 m².

The correct interpretation of the standard deviation of the given discrete distribution is:

The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.

Hence:

E(X) = 0.4(0) + 0.12(1) + 0.13(2) + 0.15(3) + 0.06(4) + 0.02(5) + 0.02(6) + 0.01(7) = 1.36

[tex]\sqrt{V(X)} = \sqrt{0.4(0-1.36)^2 + 0.12(1-1.36)^2 + 0.13(2-1.36)^2 + \cdots + 0.01(7-1.36)^2} = 1.674[/tex]

The volume of the cylinder is 254,571.43cm³.

The surface area of the cylinder is 22,628.57 cm².

A cylinder is a three-dimensional object. It is a prism with a circular base.

Volume of a cylinder =πr²h

22/7 x (30²) x 90 = 254,571.43cm³

Surface area = 2πrh + 2πr²

(2 x 22/7 x 30 x 90) + (2 x 22/7 x 30²)

The mean of a given set 3, 3, 2, 2, 2, 8, 8, 4 is 4. if the number 4 were added to the set then it won't change in mean.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

The given set is

3, 3, 2, 2, 2, 8, 8, 4

The mean will be

Mean = Sum of observations/the number of observations

= [tex]\frac{3+ 3+ 2+ 2+ 2+ 8+ 8+ 4}{8} \\\\\frac{32}{8} \\\\4[/tex]

if the number 4 were added to the set.

4 + 32 we get 36 and since you added one more number,  we will take a number of terms 9.

So, the mean becomes
