Answer:
18 m^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 5 + (6+1)) * 3
A = 1/2 ( 5+7)*3
= 1/2 (12)3
= 18
Answer:
Step-by-step explanation:
Given that you want to obtain cash by using an ATM, but it's dark and you can't see your card when you insert it. The card must be inserted with the front side up and the printing configured so that the beginning of your name enters first. Complete parts (a) through (c)
There are four positions to enter the card out of which one position is right.
a) the probability of selecting a random position and inserting the card with the result that the card is inserted correctly=1/4 = 0.25
b) the probability of randomly selecting the card's position and finding that it is incorrectly inserted on the first attempt, but it is correctly inserted on the second attempt
= Prob of wrong insertion in I attempt * prob of trying remaining 3 positions and getting right
=![\frac{3}{4} *\frac{1}{3} \\=0.25](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2A%5Cfrac%7B1%7D%7B3%7D%20%5C%5C%3D0.25)
c) Random selections can be 1,2,3 or atmost 4.
There cannot be more than 4.
A. The number of random selections required is four.
