Answer:
38
Step-by-step explanation:
For the case of a parallelogram, when the diagonals ( in our case AC & BD) are intersected, they are basically bisected ( divided into two equal halves ). Therefore when the diagonals intersect at point E, we can say that the diagonal AC is divided in two equal halves which in our case are AE and CE. since AE and CE are equal , we can say that,
Given:
Carlos buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill.
To find:
The best estimate of the amount of change he should get.
Solution:
First we need to approximate the data values.
Now, the total cost of game and batteries is
He pays with a $20 bill.
Therefore, the estimated amount of change is $6.50.
Probabilities are used to determine the chances of an event
The probability of event B is 0.62
The probabilities are given as:
To calculate the probability of event B, we make use of the following formula
So, we have:
Collect like terms
Hence, the probability of event B is 0.62
