Answer: $5.25
Step-by-step explanation:
25/100 = 0.25
0.25 * 7 = 1.75
7 - 1.75 = 5.25
Answer:
The correct option is B.
Step-by-step explanation:
The hypothesis to determine whether the vending machines are properly dispensing 12 ounces of coffee is:
<em>H</em>₀: ![\mu_{A}=\mu_{B}=\mu_{C}](https://tex.z-dn.net/?f=%5Cmu_%7BA%7D%3D%5Cmu_%7BB%7D%3D%5Cmu_%7BC%7D)
<em>Hₐ</em>: Not all means are equal.
The ANOVA output is as follows:
One-way ANOVA: Machine A, Machine B, Machine C
Source DF SS MS F P
Factor 2 8.363 4.182 31.73 0.000
Error 15 1.977 0.132
Total 17 10.340
The significance level is <em>α </em>= 0.05.
The <em>p</em>-value of the model is:
<em>p</em>-value = 0.000
Decision rule:
If the p-value of the test is less than the significance level then the null hypothesis will be rejected.
<em>p</em>-value = 0.000 < <em>α </em>= 0.05
The null hypothesis will be rejected.
Conclusion:
There is a significant difference between the means.
Thus, the correct option is B.
Answer:
$26.65
Step-by-step explanation:
41 decrease 35% =
41 × (1 - 35%) = 41 × (1 - 0.35) = 26.65
Answer:H2+Br2-->2HBr
Step-by-step explanation:
The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.
On the left you got 2xH and 2xBr.
This means you must have the same amount on the right.
2HBr =2xH + 2xBr
