Answer:
Step-by-step explanation:
The die is 6-sided. This means that there are 3 odd numbers and 3 even numbers.
When the die is rolled once, the probability of getting an odd number is:
3/6 = 1/2
The probability that this event will occur 4 out of 5 times will be:
4/5 * 1/2 = 4/10 = 2/5
Evaluating all the given expressions using the standard order of operations is as below
How to Evaluate Algebra Expressions?
We are given that;
x = -2
y = -3
z = 5
A) The algebraic equation 2x + 3y + z gives;
2(-2) + 3(-3) + 5 = -5
B) x - y gives;
-2 - (-3) = 1
C) 2(x + y)/z gives;
2(-2 - 3)/5 = -2
D) 3x² - 2x + 1
f(-2) = 3(-2)² - 2x + 1
f(-2) = 17
E) 3y(x + x² - y)
3(-3)(-2 + (-2)² - (-3))
-9 * 5 = -45
F) -z²(1 - 2x)/(y - x)
Thus;
-5²(1 - 2(-2))/(-3 - (-2))
= 625

Answer:
9 wagon stamps and 1 sailboat stamp!
Step-by-step explanation:
7×4= 28
28+3=31
4 7/15
You can only add fractions if they have the same denominator, which in this case is the 15 and the 5. So you can't add the 1/5 and the 4/15 together just yet because its not the same denominator. Multiply 3/3 to 1/5 to get the same denominator as 4/15, and it would become 3/15 because whatever you do to the top, you do to the top. Add them together and you get 7/15, and then add the whole 4 and you get 4 7/15
