Answer:
The phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population parameter implies that there is a (1 - <em>α</em>) probability that the true value of the parameter is included in the interval.
Or, the (1 - <em>α</em>)% confidence interval for the parameter implies that there is (1 - <em>α</em>)% confidence or certainty that the true parameter value is contained in the interval.
From the provided data the 95% confidence interval for the population mean parking time of students from within the various college on campus is:
CI = (9.1944, 11.738)
This 95% confidence interval implies that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738) with a specific probability or confidence of 95%.
Thus, the phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
Hello!
So the equation that you want to use is
y = mx + b
Now you can plug in both the slope and your points to find b.
3 = -1/2(2) + b
3 = -1 + b
4 = b
So now that we've found b, we can use the original equation and only plug in the slope and b
y = -1/2x + 4
So to find the y-intercept, we need to plug in 0 for x
y = -1/2(0) + 4
y = 0 + 4
y = 4
Your y-intercept is (0,4)
Hope this helps!
Answer:
Total money he had left=629.85
Step-by-step explanation:
We can express Phil's earnings from pizza sales as;
Total earnings from pizza sales=(price per slice×number of pizza slices sold)+(price per whole pizza×number of whole pizzas sold)
where;
Price per slice of pizza=1.75
Number of pizza slices sold=76 slices
Price per whole pizza=9.50 whole pizzas
Number of whole pizzas sold=64
Replacing in the expression above;
Total earnings from pizza sales=(1.75×76)+(9.5×64)=741
Total money he had left=Total earnings from pizza sales-15% of Total earnings
where;
Total earnings from pizzas ales=741
15% of Total earnings=(15/100)×741=111.15
Replacing;
Total money he had left=(741-111.15)=629.85

Explanation:
For the first option, you can’t combine two different terms. Both would have to be represented by h or by m to put the two together.
On the second option, you wouldn’t multiply the two together either because in the problem, Bianca is doing hair AND makeup which is a keyword for adding.
The third and final option is the correct one because it’s leaving the two values separate and still adding them together.
