Karen operates a hot dog stand. On Wednesday she used 9 1/3 bags of hot

trapecia [35]

<h2>Explanation:</h2>

We know that Karen operates a hot dog stand. So we have:

On Wednesday:

$\text{She used} \ 9 \frac{1}{3} \ \text{bags of hot dog buns.}$

On Thursday:

$\text{She used} \ \frac{1}{3} \ \text{as many hot dog buns as on Wednesday}$

Therefore, if x is the amount of hot dog buns she used on Thursday, then:

$x=\frac{1}{3}(9\frac{1}{3}) \\ \\ x=\frac{1}{3}\times 9+\frac{1}{3}\times \frac{1}{3} \\ \\ x=\frac{28}{9}$

Therefore, on Thursday she used 28/9 bags of hot dog buns.

A pot is being used to boil off 1 kg of water. The specific energy required to cause the phase change is 2297 kJ/kg. Assuming th

Daniel [21]

Answer:

58 seconds

Step-by-step explanation:

Given:

Initial mass of water = 1 kg

Specific energy = 2297 kJ/kg

Heat supplied by the stove = 20 kJ/s

Now,

Half water is to be vaporized i.e 0.5 kg

Thus, heat required for vaporizing 0.5 kg water = mass × specific heat

heat required for vaporizing 0.5 kg water = 0.5 × 2297 = 1148.5 kJ

Therefore,

time taken to provide the required heat = $\frac{\textup{Heat required}}{\textup{Heat supplied per second}}$

time taken to provide the required heat = $\frac{\textup{1148.5 kJ}}{\textup{20 kJ/s}}$

time taken to provide the required heat = 57.425 ≈ 58 seconds

When the outliers are removed, how does the mean change? dot plot with 1 on 50, 1 on 76, 1 on 78, 2 on 79, 1 on 80, 1 on 81, 2 o

sveticcg [70]

We can plot this data on MS Excel and determine the distribution of these data reflected on the graph. Among these numbers, 50 is the outlier since it is very far from the other numbers ranging from 76 to 83. We can perform interquartile range to determine or verify the outliers in the data set. In this respect, we can see that there is not much distribution seen. The average of all data sets is equal to 96.25. When the outlier (50) is removed, we expect the mean to become higher since a low number was ommitted including high numbers only. Outliers are obtained from special causations such as human errors.
