ANSWER
EXPLANATION
From the given information, Elena chooses a number from 1 to 10.
The sample space is
S={1,2,3,4,5,6,7,8,9,10}
n(S)=10
The numbers greater than 5 are:
E={6,7,8,9,10}
n(E)=5
The probability that, she chooses a number greater than 5 is:
Substitute the values,
Answer:
<u>160 ounces</u>
Step-by-step explanation:
A pound = 16 ounces
16x10=160 ounces
Answer:
The answer is definitely Option A

The hypotenuse is the longest side of the triangle. The opposite is the side that is across from a point/angle. The adjacent is the side next to a point/angle.
At ∅ (pretend that's theta LOL), 17 is the hypotenuse, 8 is the opposite side, and 15 is the adjacent side.
So:
sin ∅ = Opposite/Hypotenuse
sin ∅ = 
cos ∅ = Adjacent/Hypotenuse
cos ∅ = 
tan ∅ = Opposite/Adjacent
tan ∅ = 
Answer:
2 weeks
Step-by-step explanation:
Given in the question that,
Equation that represent Lisa's total amount of money
f(x) = 20 - 13x
Equation that represent Joey's total amount of money
g(x) = x² - 10
To find weeks, x, after which they will have same amount of money, we will equate both equation
<h3>20 - 13x = x² - 10</h3>
x² - 10 - 20 + 13x = 0
x² - 30 + 13x = 0
x² + 13x - 30 = 0
(x - 2)(x + 15) = 0
x = 2 or x = -15
Weeks, x, can not be negative so we will reject x = -15
Hence, after 2nd week Lisa and Joey will have the same amount of money save.
