Answer:
B) 72
Step-by-step explanation:
The n-th term of an arithmetic sequence An = a1 + (n - 1) d
Given :
a28 = 423/4 and d = 5/4
So
a28 = a1 + (28 - 1)5/4
Now plug in a28 = 423/4
423/4 = a1 + 27(5/4)
a1 = 423/4 - 27(5/4)
= 423/4 - 135/4
a1 = (423-135)/4
a1 = 288/4
a1 = 72
Thank you.

Answer:
Step-by-step explanation:
Given that,
The length of the rectangular prism = (1/2) mm
Width = (1/4) mm
Height = (3/4) mm
We need to find the volume of the prism. We know that the formula for the volume of a rectangular prism is given by :
V = lbh
Put all the values,
So, the volume of the prism is equal to .
<span>B. We can use Bernoulli trials to find how likely is that the majority of a group of 120 people have type A blood, given that 43% of people have type A blood. There are two possible outcomes (a person eithr has Tpe A blood or does not), there is a constant probability of success (43% of people have Type A blood), and the trials are independent (wether each person has Type A blood does not depend wether others have Type A blood).</span>
