if we buy 20 pickles what is the experimental probability of winning 5 or more tickets

Answers

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]

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

Answers

It should be D.30000 = 18500

Here is the histogram of a data distribution. All class widths are 1.

What is the median of this distribution?
A. 6
B. 7
C. 5
D. 8

Answers

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.

Recall the experiment comparing patients 4 weeks after surgery for carpal

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.

Answers

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

Answers

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.
