Answer:
11.438 million
Step-by-step explanation:
To find the expected value, you multiply the probability by the grand prize of the lottery ticket.
The lottery ticket has a grand prize of 30.1 million.
The probability of winning the grand prize is 0.38
The expected value of the ticket is
We can see that a number ending in 0 occurs every 5 numbers. We also identify that all figures in pattern are even
Answer:
Probability of choosing first girl = 11/20
Next one would be 10/19
11/20 x 10/19 = 11/38
Probability = 11/38
Answer:
<em>The app's estimate was 38.4 minutes.</em>
Step-by-step explanation:
Suppose, the app's estimated time was minutes.
Given that, it took 48 minutes to drive downtown. So, <u>the error in estimated time by the app</u> minutes.
It is also given that the error was 20%. So, <u>the amount of error</u> minutes.
Thus, the equation will be......
So, the app's estimate was 38.4 minutes.
Look at the picture.
ΔPQB and ΔNQB are <span>congruent therefore m∠PQB = m∠NQB
therefore m∠PQN = </span><span>m∠PQB + m∠NQB
m∠PQN = 45° + 45° = 90°</span>
