What is the probability of not drawing a green marble from a jar containing 7 red, 4 green, 3 white, and 9 blue marbles?

Answers

Answer 1
Answer: 7+4+3+9
11+12
23

(23)/(23) - (4)/(23)

(23-4)/(23)

(19)/(23) chance
Answer 2
Answer:

Answer:

Probability of not drawing a green marble is 19/23.

Step-by-step explanation:

A jar is containing 7 red, 3 white, and 9 blue marbles.

Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors

P(G) = 4/(7 + 4 + 3 + 9)

P(G) = 4/23

Now the probability of not drawing a green marble = 1 - probability of drawing a green ball

P = 1 - 4/23 = 19/23

Therefore answer is 19/23.

Tickets to a baseball game cost $18.95, $12.95, or $9.95. A hot dog and soda combo costs $5.50. The Madison family is having a reunion. They buy 10 tickets in each price category and plan to buy 30 combos. What is the total cost for the tickets and mealsI GOT 583.5 JUST WANT A SECOND CHECK

Answers

Hmmm Interesting: 189.5+129.5+99.5+53
I got 471.5 Dollars....

Because Look If they buy 10 tickets each category it be 18.95 times 10= 189.5
then 12.95 times= 129.5 , Then 9.95 times= 99.5.... Also if they plan to get 30 combos it be also 5.50 times 30,,, You add the answers and it will give you 471.5 dollars. You can try doing it in a caculator (:
You want to times each ticket price by 10 then add them together, then $5.50 by 30.

$18.95*10 = $189.50
$12.95*10 = $129.50
$9.95*10 =  $99.50
$189.50+$129.50+$99.50 = $418.5

Then do $5.50*30 = $165

Then add them both together.
418.5 + 165 = 583.5

You were correct.

Answer:

(a) 0.00000221    (b) 4.2 x 10^(5)

Step-by-step explanation:

(a)  10^(-6) means you need to move the decimal left (because of the negative) 6 spaces. So you have 2.21 move the decimal 6 spaces left and you end up with 0.00000221

(b) If you have 420,000 and you count 5 spaces from the last number, that leaves the decimal inbetween the 4 and 2 so your answer will be 4.2 x 10^(5)

Gretchen is using an overhead projector to enlarge a drawing so she can make a poster. The original drawing measures 60 mm wide by 80 mm high. She moves the projector so that the width of the projected image is 300 mm. If the original drawing and the projected image are similar figures, what will be the height of the projected image?

Answers

so 60 by 80,
60 <80 so 60=width
she moves it so that width=300
findn height

60:300=80:x
60/300=80/x
muliplyb oth sides by x
60x/300=80
x/5=80
mulitpliy both sides by 5
x=400

the height=400 mm

Answer:

400mm

a population decrease from 404 million to 288 million .which of the following is the percent decrease of the population

Answers

288/404 = 0.71

Hence 0.71 x 100 = 71%
Example:
12 is 20% of 60. In order to get 12 percent of 60, all you need to do is to divide 12 with 60. To get the percent means to get the parts of 100. To get it in the form of percent, just multiply the quotient by 100. 12/60=.2 x 100 = 20% .

Answer:

Percentage decrease in Population = 28.71%

Step-by-step explanation:

Decrease in population = 404 Million - 288 Million = 116 Million

Percentage decrease in Population = (116 / 404)*100 = 28.71%
