Complement angles add up to 90 degrees. a supplement angle means that the two angles add up to 180 degrees.

with that in mind, 40+50=90
50+130=180

Answer: The area of Figure ABCDE is 79.5 square units.

Step-by-step explanation:

<em>Triangle ABC is the top triangle of Figure ABCDE.</em>

<u>Triangle ACD is the triangle on the right of Figure ABCDE.</u>

Triangle AED is the triangle on the bottom left of Figure ABCDE.

So, we need to add <em>23.85</em>, <u>29.4</u>, and 26.25 to get the area of Figure ABCDE!

23.85 + 29.4 + 26.25 = 79.5

A master student is planning to take a qualifying exam in the coming summer. She has three chances. The first one is in June. If
Soloha48 [4]

Answer:

Step-by-step explanation:

Given

P_1=Probability of clearing exam in 1 st attempt=0.5

P_2=Probability of clearing exam in 2 nd attempt=0.7

P_3=Probability of clearing exam in 3 rd attempt=0.8

Probability that she passes the exam=P(1 st\ attempt)+P(1\ fail)\cdot P(2\ pass)+P(1\ fail)\cdot P(2\ fail)\cdot P(3 rd pass)

P=0.5+0.5\times 0.7+0.5\times 0.3\times 0.8=0.97

(b)P(Pass qualification on 2nd try|passes qualification)

P(Pass qualification on 2nd try|passes qualification)=\frac{P(fail\ on\ 1 )\cdot P(pass\ in\ 2nd)}{P(passes)}

P(Pass qualification on 2nd try|passes qualification)=\frac{0.5\times 0.7}{0.97}=0.3608

247 students went on a field trip. six buses were filled and 7 students traveled in cars. How many students were in each bus ?
Nuetrik [128]

from all the 247 students, 7 went on by cars, meaning they didn't fit in the buses, so they students that went in the buses are 247 - 7 = 240.

now, we know there were 6 buses, so dividing 240 evenly by 6, 240/6  = 40.
