The square of the diagonal (d1) of the end face is
.. (d1)^2 = (3 in)^2 +(5 in)^2 = (9 +25) in^2 = 34 in^2

The square of the longest diagonal (d2) will be given by
.. (d2)^2 = (3x in)^2 +(d1)^2
.. = (9x^2 +34) in^2

So, the longest diagonal is
.. d2 = √(9x^2 +34) in

Question 3
Natasha2012 [34]

Answer:

60,000 grams

Step-by-step explanation:

Find how many grams she weighs by finding how many grams are in 60 kilograms.

There are 1000 grams in a kilogram, so to find her weight in grams, multiply 60 by 1000:

60(1000)

= 60,000

So, Julie weighs 60,000 grams

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probabilit
Verdich [7]

Answer:

a) Standard Deviation = 2.74

b) Significantly Low = values below 24.52 (or equal)

Significantly High = values above 35.48 (or equal)

Step-by-step explanation:

This is binomial probability distribution problem.

Where n = 40 [groups of 40, total trials]

p = 0.75 [probability of success]

a)

The formula for standard deviation is:

Standard \ Deviation = \sqrt{np(1-p)}

We know  n = 40 and p = 0.75, so the standard deviation is:

Standard \ Deviation = \sqrt{np(1-p)} \\Standard \ Deviation = \sqrt{(40)(0.75)(1-0.75)}\\ Standard \ Deviation = 2.74

b)

the range rule of thumb tells us that usual range of values is within 2 standard deviation of the mean. First let's calculate mean.

We know,

Mean = n * p = 40 * 0.75 = 30

So

Mean - 2* Standard Deviation = 30 - 2(2.74) = 24.52

and

Mean + 2* Standard Deviation = 30 + 2(2.74) = 35.48

Significantly Low = values below 24.52 (or equal)

Significantly High = values above 35.48 (or equal)
