Let the amount of dollars in goods sold be x, then her earning is 1850 + (4/100)x = 1850 + 0.04x.
For her to earn more than $2300, we have:
1850 + 0.04x > 2300
0.04x > 2300 - 1850
0.04x > 450
x > 450 / 0.04
x > $11,250
Sin60=DF/FE
Root 3/2= DF/ 18 Root 3
DF= 18*3/2
DF= 27 units
cos60=DE/FE
1/2=DE/18 Root 3
DE= 18 Root 3/2
DE= 9 Root 3 units
Actually Welcome to the Concept of the Congruency.
Q-4 answer is SAS, since alternate angles are equal.
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).
Answer:
Donny's bagels is the better deal.
Step-by-step explanation:
Bob's bagels are 10 for $11
Unit price for Bob's bagels = $11 / 10 bagels = $1.10 per bagel
Donny's bagels are 4 for $3
Unit price for Donny's bagels = $3 / 4 bagels = $0.75 per bagel
because Donny's unit price is less than that of Bob's (i.e each of Donny's bagels cost less than each of Bob's bagels), thus Donny has the better deal
