Answer:
1/8
Step-by-step explanation:
To find which bag weight Carla needs, the first step is to find the total weight of the bags shown in the line plot.
There are three -pound bags.
There are six -pound bags.
There are four -pound bags.
Multiply the weight and number of each bag to find the total weight of each different weight bag.
Now, add the three totals.
Finally, subtract the total weight from four pounds in order to find which weight Carla needs.
So, Carla should pick one -pound bag of candy to total four pounds.
Answer:
½÷3=0.17
if you're talking about the app, i don't get too
Volume is found by multiplying the length, width, and height as follows:
However they have already told us in the question that the area of the base is
. This was found by multiplying the length and the width, which means that they have done this for us already! Now we need to take the height and multiply is by
to get the total volume of the tank. Let's do that now:
So now we know that
the total volume of the tank is .
Answer:
D. Fail to reject the null hypothesis, since 0.15 > 0.05.
Step-by-step explanation:
P-value and decision regarding null hypothesis:
If the p-value is larger than the significance level, we do not the null hypothesis.
Otherwise, we reject the null hypothesis.
In this question:
The test statistic is χ2=3.79, with a p-value of 0.15.
The level of significance is 0.05.
Since 0.15 > 0.05, we fail to reject the null hypothesis, and the correct answer is given by option D.
Answer: 15 divided by -5 = -3
