A bag contains tickets numbered 1 through 5. Use the probability distribution to determine the probability of drawing an odd num

Makovka662 [10]

Answer:

The probability of drawing an odd numbered ticket is 60%.

Step-by-step explanation:

Odd numbered tickets:

Probability of one is 1/5 plus half of 1/5.

$P(X = 1) = \frac{1}{5} + \frac{1}{10} = \frac{3}{10}$

Probability of 3 is half of 1/5.

$P(X = 3) = \frac{1}{10}$

Probability of 5 is 1/5. So

$P(X = 5) = \frac{1}{5}$

Probability of drawing an odd numbered ticket:

$p = P(X = 1) + P(X = 3) + P(X = 5) = \frac{3}{10} + \frac{1}{10} + \frac{1}{5} = \frac{4}{10} + \frac{2}{10} = \frac{6}{10} = 0.6$

0.6*100% = 60%

The probability of drawing an odd numbered ticket is 60%.

Doug estimates that his soccer team will win 7 games this year. The team actually wins 10 games. What is the percent error of Do

baherus [9]

Answer: 30%

Step-by-step explanation:

Percent error = $\dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%$

Estimated number of games win this year = 7

Actual number of games won = 10

Now , the percent error of Doug’s estimate = $\dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%$

Hence, the percent error of Doug’s estimate = 30%

Sally has 2 cats and each cat eats 1/4 of a tin of cat food each day.

Mashutka [201]

If one cat eats 1/4 of a tin per day then two cats eat 1/2 of a tin per day.

We have 9 tins so if each day cats eat 1/2 we have to divide 9 with 1/2 and we get 18 which is for how many days she can feed the cats until she runs out of food.

Hope this helps.

to find the slope of two points you have to subtract them (x1,y1), (x2,y2)

Steps:

$(X_1,Y_1) (X_2, Y_2)$

$\frac{3 - 10}{8 - 7} = -\frac{7}{2}$

Steve has a square patio with sides of length 9 feet. He plans to enlarge it to a rectangular patio by

Greeley [361]

Answer:

51ft^2

Step-by-step explanation:

Given data

Side of square patio= 9ft

Area= 9*9= 81 ft^2

New length = 9+3= 12ft

New Widht = 9+2= 11ft

New Area= 12*11

New Area= 132ft^2

Hence the area added is

=132-81

=51ft^2
