It could be a building with a triangular top. If the building had a triangular top, then it must have 3 rectangles as its sides. So your answer would be, a building with a triangular top.
Answer:
Step-by-step explanation:
Total = 50
Males = 20
Females = 30
a) P(exactly 1 female) = P(1 female , 2 male)
(30C1 * 20C2) / (50C3) = 30*190/19,600 = 0.2908
b) P(at least 2 males) = 1 - (P(0 males) + P(1 males))
= 1 - 30C3 * 20C0/50C3 - 30C2 * 20C1/50C3
= 1 - 4060*1/19,600 - 435*20/19,600 = 6840/19600 = 0.3489
Answer:
There are no like terms.
so its -7a+2b
Step-by-step explanation:
No hablo expanol
7(z+2)-3z=44
7z+14-3z=44
7z-3z+14=44
4z+14=44
-14 -14
4z+14-14=44-14
4z+0=30
4z=30
1/4 1/4
(4z)/4=30/4
(4/4)z=15/2
1z=15/2
z=15/2
z=15/2
Answer:
The coefficient is "12"
Step-by-step explanation:
Step 1: Encircle the variable along with its power whose coefficient we are finding.
Step 2: Leave that variable and consider all other numbers or variables written with it. That will be the coefficient.
