Answer:
A. $21.59
Step-by-step explanation:
$151.13 ÷ 7 tons= $21.59 each per ton
Step-by-step explanation:
f(x) = x² − 6x + 9
f(½) = (½)² − 6(½) + 9
f(½) = ¼ − 3 + 9
f(½) = 6¼
The value is 6¼, or as an improper fraction, 25/4.
Answer:
x = 19/2 or 9.5
Step-by-step explanation:
Hello!
We can distribute the parenthesis and solve.
<h3>Solve</h3>
- 2(4x - 3) = 5(2x - 5)
- 2(4x) - 2(3) = 5(2x) - 5(5)
- 8x - 6 = 10x - 25
Move all x terms to one side and integer terms to the other
- 8x - 6 = 10x - 25
- -6 + 25 = 10x - 8x
- 19 = 2x
- x = 19/2
- x = 9.5
Answer:
0
Step-by-step explanation:
H0 : μ = 840
H1 : μ < 840
Sample size, n = 49
Standard deviation, s = 14
Test statistic = (xbar - μ) ÷ (s/√(n))
Test statistic = (830 - 840) ÷ (14/7)
Test statistic = - 10 / 2
Test statistic = - 5
The Pvalue ;
Pvalue = P(Z < - 5) = 0 (Z probability calculator)
The Pvalue = 0
