Answer:
Step-by-step explanation:
A shopper paid $2.52 for 4.5 pounds of potatoes. This means that the unit price for each potato would be
2.52/4.5 = 0.55556
Approximately $0.6 per pound.
The shopper paid $7.75 for 2.5 pounds of broccoli. This means that the unit price for each broccoli would be
7.75/2.5 = $3.1 per pound.
The shopper paid $2.45 for 2.5 pounds of pears. This means that the unit price for each pear would be
2.45/2.5 = $0.98 per pound
It is either A or B. I am not really sure.
Answer:
b. Null: The population average VDAS score for early birds is the same as the population average VDAS score for night owls.
Alt: The population average VDAS scores are different for the two groups.
Step-by-step explanation:
Given
The above data
Required
Determine the null and alternate hypothesis
When looking out for the null hypothesis, only options with equality statements or equal sign should be selected as the null hypothesis.
i.e. statements like "equal to", "the same as", etc.
The alternate hypothesis will then contain inequalities or inequality statements
<em>From the list of options, only option (b) is correct.</em>
42
(125/3 = 41.6..., 41.6... rounded is 42)
Answer:
Domain of the function represented in the graph is given by he inequality 
.
Step-by-step explanation:
We are given the following information in the question:
- The graph shows the plot for quantities of green and yellow paints used for each mix.
- The x-axis shows the quantity of yellow paint used in millimeters.
- The y-axis shows the quantity of green paint used in millimeters.
We have to find a domain for the function shown in the graph.
Domain of a function is basically the set of all values of x for which the function is defined.
If we observe the graph, particularly the x-axis, the plot starts from value 2 and goes upto 10.
So x can take values from 2 to 10.
This can be represented with the help of inequality:
Hence, domain of the function represented in the graph is given by he inequality .
