Answer:
No
Step-by-step explanation:
Each "x" should have a corresponding "y" value. In this case, however, an x has two different y values which would not make this a function. You can check this through the vertical line test.
So lets go step by step, first lets see how much Reagan spent, that is 2 banana splits, $3.25 each, that is:
total spent = 2*3.25 = 6.50
So Reagan spent $6.50 of her weekly allowance, and the problem says that $6.50 represents 26% of her weekly allowance, the question is to find out how much represents the 100% of her weekly allowance.
We can solve this using a rule of three, simple, with direct proportion:
26% -----> $6.50
100% ----> x
x = (100)(6.50)/26 = 650/26
x = 25
therefore Reagan's weekly allowance is $25
We have to find that whole number from which we divide 7 so we will get greater than 800.
As we know 7* 800 = 5600
So the least whole number greater than 5600 is 5601.
So we can say

Step-by-step explanation:
Dada la siguiente información:
Tasa de interes anual (i)= 4,8%
Inversión inicial (VP)= $1.000.000
<u>Para calcular el valor final (VF), debemos usar la siguiente formula:</u>
VF= VP*(1 + i)^n
<u>Para 5 años:</u>
VF= 1.000.000*(1,048^5)
VF= $1.264.172,72
<u>Para 18 años:</u>
VF= 1.000.000*(1,048^18)
VF= $2.325.429,02
Answer:
No. When all you want to do is estimate a population parameter, you should construct a confidence interval.
Step-by-step explanation:
In this case, there is no other prior estimation about the population to test (a hypothesis to nullify). The only thing you can do is construct a confidence interval of the proportion, where the standard deviation can be calculated in function of the proportion and the sample size.
The right answer is E: "No. When all you want to do is estimate a population parameter, you should construct a confidence interval."
