HELPPP ASAPPP ON ALL MY QUESTIONS Using the line of random numbers to run one simulation, what proportion of students tried out for a
sport?
O 0.40
A study reported that about 40% of high school
students have tried out for a sport at their school. To
find out if this applies to Jessica's school, she surveyed
an SRS of 20 students. Nine of them said that they had
tried out for a sport. To see if this result is surprising, a
simulation is to be conducted to estimate the probability
of obtaining a sample result as high as this one.
Let 0-3 represent students who tried out for a sport and
4–9 represent students who did not try out for a sport
0 0.45

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
