A car’s value depreciates at a rate of 3.4% per year. The car was worth $30,000 when it was new.
Which equation could be used to determine when the car will be worth $18,500, where x is time in years?
A. 18500 = 30000 (0.034)^x
B. 18500 = 30000(0.966)^x
C. 30000 = 18500(0.34)^x
D. 30000 = 18500 (0.966)^x

Tommy plays a game in which he rolls two standard number cubes. On any one roll, what is the probability that the sum of the numbers rolled is even? Show your work.
if you can attempt to type out a table... that would be great lol.
Answer: 50% or 1/2
Step-by-step explanation:
number of possible combos:
1+1, 1+2, 1+3, 1+4, 1+5, 1+6
2+1, 2+2, 2+3, 2+4, 2+5, 2+6
3+1, 3+2, 3+3, 3+4, 3+5, 3+6
4+1, 4+2, 4+3, 4+4, 4+5, 4+6
5+1, 5+2, 5+3, 5+4, 5+5, 5+6
6+1, 6+2, 6+3, 6+4, 6+5, 6+6
number of even sums within combos:
1+1, 1+3, 1+5
2+2, 2+4, 2+6
3+1, 3+3, 3+5
4+2, 4+4, 4+6
5+1, 5+3, 5+5
6+2, 6+4, 6+6
TOTAL combos:
36
TOTAL even sums:
18
so that means 18/36 or 1/2 of the possible combinations has a sum of an even number.
sorry it’s not a table but I literally worked it out while answering so that’s all my work
Recall the experiment comparing patients 4 weeks after surgery for carpal
tunnel syndrome. The patients who had endoscopic surgery demonstrated
a mean pinch strength of 9.1 kg compared to 7.6 kg for the open- incision
patients.
4. What hypotheses would you test?
5. The P-value of the test was less than 0.05. State a brief conclusion.
Answer:
4. H0: u1= u2 Ha; u1≠ u2
5. The smaller value of p supports the null hypothesis.
Step-by-step explanation:
4. The null and alternate hypotheses are
H0: u1= u2 i.e there no difference between the mean pinch strengthof the two surgeries
against the claim
Ha; u1≠ u2 i.e there a difference between the mean pinch strengthof the two surgeries
It can be written like this as well
H0: u1 -u2= 0 i.e there no difference between the mean pinch strengthof the two surgeries
against the claim
Ha; u1 -u2≠ 0 i.e there a difference between the mean pinch strengthof the two surgeries
Part 5. The test having a p- value less than 0.05 tells that the null hypothesis cannot be rejected. Theres no evidence to reject the null hypothesis.
The smaller value of p supports the null hypothesis.

Marco gana 1200 mensualmente . La mitad de su dinero es entregado a su mama de lo que le queda gasta en la tercera parte en ropa cuanto dinero le sobra
Answer:
A Marco le sobra 400.
Step-by-step explanation:
Marco gana 1200 mensualmente. La mitad de su dinero es entregado a su mamá.
La mitad de un número se calcula dividiendo el número por 2. Por lo que la mitad de lo ganado por Marco se calcula:
1200 ÷2= 600
Por lo que Marco entrega a su mamá 600 mensualmente, y quedan 600, obtenido de la resta entre lo ganado mensualmente y lo entregado a su madre.
De lo que le queda gasta en la tercera parte en ropa. La tercera parte de un número se calcula dividiendo el número por 3. Entonces:
600 ÷3= 200
Entonces Marco gasta 200 en ropa. Por lo que resta es 400, obtenido por la diferencia entre los 600 que poseía luego de entregar dinero a su madre y lo gastado en ropa.
Entonces, a Marco le sobra 400.

A. 6
B. 7
C. 5
D. 8
The median of the distribution of the class is 5 for the distribution 1,2,3,45,6,7,8,9,10
What is median?
The median is the central value of the data set.
How to find the median?
To find the median we have to use the formula:
If n is odd (n/2),(n+1/2)
If n is even (n/2)
Here the n is 10 so the median will be (10/2)=5
Hence the median will be 5 if the distribution is 1,2,3,4,56,7,8,9,10.

if we buy 20 pickles what is the experimental probability of winning 5 or more tickets
Answer:
[tex]Pr = 0.66[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
[tex]P(x \ge 5)[/tex]
From the attachment, we have:
[tex]S = 2 + 8 + 4+20+21+19+17+5+2+2[/tex]
[tex]S =100[/tex] ---- the sample size
Next, we list out all outcomes more than or equal to 5.
i.e.
[tex]x \ge 5[/tex]
5 is represented with the vertical blue rectangle (with frequency 21).
So, the other elements are to the right of frequency 21.
So, we have:
[tex]x \ge 5 = 21+19+17+5+2+2[/tex]
[tex]x \ge 5 = 66[/tex]
The probability is then calculated as:
[tex]Pr = \frac{x \ge 5}{S}[/tex]
This gives
[tex]Pr = \frac{66}{100}[/tex]
[tex]Pr = 0.66[/tex]
