Alrighty

we gots 1/4 circle and paralellogram

area circle=pi times radius^2
area paralelogram=base times height


1/4 circle is
radius is 10 so
area part circle is 1/4 times pi times 10^2=100/4pi=25pi=78.5 m²

area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30

30+78.5=108.5 m² is the area

Seventy-six percent of sunflower seeds will germinate into a flower, and a sample of 800 such sunflower seeds is randomly select
ollegr [7]

Answer:

12.08

Step-by-step explanation:

For each sunflower, there are only two possible outcomes. Either it germinates, or it does not. The probability of a sunflower germinating is independent of other sunflowers. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

Seventy-six percent of sunflower seeds will germinate into a flower

This means that p = 0.76

Samples of 800:

This means that n = 800

The standard deviation for the number of sunflower seeds that will germinate in such samples of size 800 is:

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{800*0.76*0.24} = 12.08

What is the lateral area of the rectangular prism with a base length of 17 m, a base width of 7 m, and a height of 5 m?
mrs_skeptik [129]
length: \ l=17 \ m \\width = \ 7 \ m\\ height:\ 5 \ m \\\\ lateral \ area \ =(2l+2w)\cdot h \\ \\A_{l} = (2\cdot 17+2\cdot 7)\cdot 5=(34+14)\cdot 5=48\cdot 5=240 \ m^2
