Step-by-step explanation:
This is a probability related problem.
Probability is the likelihood of an event to occur;
Pr = ![\frac{number of possible outcomes}{Total sample space}](https://tex.z-dn.net/?f=%5Cfrac%7Bnumber%20of%20possible%20outcomes%7D%7BTotal%20sample%20space%7D)
The sample space here is from 1 to 25 which is 25
A.
Pr of a card marked 8; we have just 1 possible outcome;
Pr(8) =
B.
Pr of drawing a card that is a multiple of 5;
Multiples of 5 = 5, 10, 15 and 25
Pr (multiples of 5) =
C.
Pr of drawing a card with odd numbers:
Number of odd numbers between 1 and 25 = 13
Pr(odd numbers) =
D.
Pr of drawing a number with square number on it;
Square numbers between 1 and 25 = 1, 4, 9, 16 and 25
Pr(square numbers) =
= ![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
Answer:
Zachary invests $470 into the account that earns 5% simple interest. At the end of 2 years, the account balance is $517
Step-by-step explanation:
I took the test
Multiply both sides by 2.
2m = a + b
Subtract both sides by b.
2m - b = a
5 minutes x minutes
--------------- = -------------
4 dishes 24 dishes
using cross products
5 * 24 = 4 * x
divide each side by 4
5*24/4 = x
30=x
It will take 30 minutes
