WHAT SUBJECT IS THAT? TELL ME WHAT SUBJECT AND I'LL ANSWER IT PROPERLY
R = (3.53/1.46)^{1/10}-1 = 0.0923
Step-by-step explanation:
#1.
(a + 2b)²
<em>Using identity (x + y)² = x² + 2xy + y², we get:</em>
= (a)² + (2b)² + 2 × (a) × (2b)
= a² + 4b² + 4ab
= a² + 4ab + 4b² Ans.
#2.
(5x - 3y)²
<em>Using identity (a - b)² = a² - 2ab + b², we get:</em>
= (5x)² + (3y)² - 2 × (5x) × (3y)
= 25x² + 9y² - 30xy
= 25x² - 30xy + 9y² Ans.
#3.
(3a + 4)(3a - 4)(9a² + 16)
<em>Using identity (x + y)(x - y) = x² - y², we get:</em>
= [(3a)² - (4)²][9a² + 16]
= (9a² - 16)(9a² + 16)
= (9a²)² - (16)²
= 81a⁴ - 256 Ans.
Negative 5 is to your left 5 is to your right hope that helps?
Answer:
The correct option is C 20.1%.
Step-by-step explanation:
The probability distribution chart representing the opinions of employed adult women about government funding for day care is as follows:
Rating (<em>X</em>) Probability (<em>p</em>)
1 0.110
2 0.206
3 0.464
4 0.201
5 0.119
The ratings are defined as follows:
1: too little
2: helpful but not enough
3: make a difference but insufficient
4: sufficient
5: generous
The probability of women who think that the support is sufficient is, 0.201.
The percentage is: 0.201 × 100 = 20.1%
Thus, the percentage of women who think that the support is sufficient is 20.1%.
The correct option is C.
