The answer is A
1 1/2 *2 *1 1/2 = 4.5 or 4 1/2

Answer: approximately 2.11</h3>
Work Shown:
x = 108 is the raw score we want to transform
mu = 104 is the mean
sigma = 1.9 is the standard deviation
z = (x-mu)/sigma
z = (108-104)/1.9
z = 4/1.9
z = 2.10526315789473 which is approximate
z = 2.11 rounding to two decimal places
I'm rounding to two decimal places because many z tables will work with this level of precision.
F(x)=5x^3-2x^2+3
=5 2^3 - 2 2^2 +3
=5 (8) - 2 (4) +3
= 40 - 8 + 3
= 35
answer is A.35
Answer:
8) 10c² - 2c + 5
9) 5a²b² - ab²
Step-by-step explanation:
8c² - c + 3 + 2c² - c + 2 =
10c² - 2c + 5
6a²b² + 3ab² - a²b² - 4ab² =
5a²b² - ab²
Answer:
The product of two rational numbers is always rational
Step-by-step explanation:
- DEFINITION: a number is said to be rational if and only if it is expressed in p/q form i.e, as a fraction(p/q) where, p,q are integers and
- now, let a/b and c/d be two rational numbers.
- the product of them : ac/bd.
- FACT : if we multiply 2 integers, then the product will be an integer.
- so, ac and bd are both integers for sure and bd is not zero because none of b or d is zero.
- therefore, as ac/bd satisfy the definition of a rational number, it is a rational number.
- hence, we can now generalize that, The product of two rational numbers is always rational.
