Answer:
2.) $520
3.) less
Step-by-step explanation:
I'm going to assume that the interst is compoudning and is convertable once a year
The compound interest formula for interest compounding only once a year is as follows
plug in the numbers and get
3.) If the interest rate is lower at the credit union he would obvioulsy be paying less (assuming that this interest rate is convertable annually as well)
Answer:
After statistical analysis we find that the critical value with respect to a level of significance of 0.01 is greater, we deduce that if there is a difference in the number of rounds played per day in the week
Step-by-step explanation:
120+105+100+150+150=625/5=125= Expected frecuency
(observed - expected)^2/expected
Monday. 120 2
Tuesday. 105. 3.2
Wednesday. 100. 5
Thursday. 150. 5
Friday 150. 5
The total sum will give us the statistical chi-square test that is 20.2
according to the previous listing we look for the degrees of freedom:
5-1=4
Critical value = 3.747
After statistical analysis we find that the critical value with respect to a level of significance of 0.01 is greater, we deduce that if there is a difference in the number of rounds played per day in the week
we have
--------> equation
let's change of variable
--------> equation
substitute in the equation in equation
therefore
<u>the answer is</u>
Answer: 3xy^2 - 3x^2 -1
Step-by-step explanation:
5xy^2 - 2xy^2 = 3xy^2
3x^2 becomes negative due to the negative out in front of the parenthesis
-2y^2 + 2y^2 = 0
-8+7 = -1
