Answer:
let the number of calories from lunch be called L. As such, breakfast is then L + 128, and dinner is 2L - 400. We can then sum the three meals and equate it to the total caloric intake, the known value of 1932.
So: 1932 = L + L + 128 + 2L - 400 = 4L - 272.
Lunch = 551
Breakfast = 551 + 128 = 679
Dinner = 2*551 - 400 = 702

Answer:
An equation is used when we have paired sets of data to describe how the values in one pair change when we alter the values in the other set.
On the other hand, a series gives a general formula of determining the value of the nth observation when the values have been arranged in increasing order
Step-by-step explanation:
An equation such as; y = 3x+5 models the relation between the response variable y and the predictor variable x. It tells us how y changes when x is altered by a certain magnitude. The value 3 is described as the slope while 5 is the y-intercept.
On the other hand, a series such as; score = 2 + 3n provides a general formula that can be used to determine the score of the nth individual in a sample or population.
Using the z-distribution, as we are working with a proportion, it is found that the test statistic for their significance test is given by: z = 2.
<h3>What are the hypothesis tested?</h3>
As stated in the problem, they are:
<h3>What is the test statistic?</h3>
It is given by:
In which:
- is the sample proportion.
- p is the proportion tested at the null hypothesis.
In this problem, we have that;
Hence:
The test statistic for their significance test is given by: z = 2.
