I’m pretty sure the answer is that last one where t is less than or equal to -12
Im 90% sure it’s H (pls mark as brainliest
Answer:
42. acute
43. obtuse
Step-by-step explanation:
Obtuse: which one of the interior angles measures more than 90° degrees, then the rest are less than ninety.
Acute: all less than ninety and all different.
Answer:
See below in bold,.
Step-by-step explanation:
There are 30-17 = 13 boys in the class.
a. Prob(First is a boy ) = 13/30 and Prob( second is a boy = 12/29).
As these 2 events are independent:
Prob( 2 boys being picked) = 13/30 * 12/29 = 26/145 or 0.179 to the nearest thousandth.
b. By a similar method to a:
Prob ( 2 girls being picked) = 17/30 * 16/29 = 136/435 = 0.313 to the nearest thousandth.
c. Prob (First student is a boy and second is a girl) = 13/30 * 17/29 = 221/870.
Prob ( first student is a girl and second is a boy) = 17/30 * 13/29 = 221/870
These 2 events are not independent so they are added:
Prob( one of the students is a boy) = 2 (221/870 = 221/435 = 0.508 to the nearest thousandth.
Check the picture below.
so the volume of the smaller cube will just be (1/3)³.
how many of those cubes will take to fill up the larger cube?
namely
how many times does (1/3)³ go into 44?
