Ethan's class is handing out balloon arrangements consisting of 4 balloons each. Each
balloon has an equally likely chance of being red, blue, or yellow. Ethan created a
spinner to simulate this probability. Here is Ethan's data from 30 trials of 4 spins on
the spinner (r = red, b = blue, y = yellow):
ybrr bybb rbbb rrry rbbb rryy yybb ryry ryyr rbyr ryyr rryy yrby bbyy byyr byyr
byyb rbby ybry rryy rbrr rybb bbbr rrbrybry ryrr rryb rrrb rryr
According to this data, what is the experimental probability that an arrangement will
not contain any balloons that are red?
0.133

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

1.) 21

2.) 0.453

3.) 1.5

4.) 48

5.) $ 22

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
