Margo places 6 pennies and 4 nickels in a jar. For the experiment, she selects a penny, replaces it, and selects another penny. If Margo repeats the experiment 100 times, how many times can she expect to select two pennies?​

Answers

Answer: She is expected to select 2 pennies 36 times.

Step-by-step explanation:

In jar , we have

6 pennies and 4 nickels

Total coins = 10

The probability of getting two pennies ( with replacement) =

[tex]\dfrac{\text{Number if ways to get 2 pennies}}{\text{Total ways to select 2 coins}}\\\\=\dfrac{6\times6}{10\times10} \ \ [\text{independent events]}\\\\=\dfrac{36}{100}[/tex]

If Margo repeats the experiment 100 times, then expected number of times to select two pennies = [tex]\dfrac{36}{100}\times100=36[/tex]

She is expected to select 2 pennies 36 times.

We will see that Margo can expect to randomly select two pennies 36 times.

Probability of selecting two pennies at random.

The probability of selecting a penny at random is equal to the quotient between the number of pennies in the jar and the total number of coins in the jar, this is:

p = 6/10

And doing that two times, needs that probability two times, so the probability of selecting two pennies is:

p = (6/10)*(6/10) = 36/100

How many times she can expect to select 2 pennies in 100 attempts?

Here we just need to multiply the above probability by 100, we will get:

(36/100)*100 = 36

So she can expect to get two pennies 36 times.

Answers

500.

Solution:  210 is 42% of X  

Equation: Y = P% * X  

Solving our equation for X

X = Y/P%

X = 210/42%  

Converting percent to decimal:

p = 42%/100 = 0.42  

X = 210/0.42  

X = 500

Put the following equation of a line into slop-intercept form, simplifying all fractions.
2y - x = -8

Answers

y=1/2x-4
First, you use the inverse operation to add x to -x
2y-x=-8
+x +x
—————
2y=x-8
Next you divide 2 by both sides of the equation
2/2y=x-8/2
The twos on the left side of the equation cancel out and you simplify the rest of the problem...
y=x/2-4

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If 3/4 of the drink is apple juice and 1/10 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form

Answers

Step-by-step explanation:

Let's assume x = apple juice, y = orange juice, and z = cranberry juice

[tex]1 = x + y + z \\ 1 = \frac{3}{4} + \frac{1}{10} + z \\ z = 1 - \frac{3}{4} - \frac{1}{10} \\ z = \frac{3}{20} [/tex]

x : y : z = 3/4 : 1/10 : 3/20

If we were to make them all in the same denominator, x : y : z = 15/20 : 2/20 : 3/20.

[tex] \frac{3}{4} \times \frac{5}{5} = \frac{15}{20} \\ \\ \frac{1}{10} \times \frac{2}{2} = \frac{2}{20}[/tex]

180°(5-2)=540°

The sum of the interior angles of the pentagon is 540°

So:

P+Q+R+S+T=540°

(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°

4x+2+4x-10+5x-11+260=540

If tommy rode his bike 4.3 miles a day, 3 days a week for 5 years delivering news papers and he dropped 22.7 newspapers every 1/4 mile. How many newspapers did tommy drop?

Answers

Answer:

277 848 newspapers.

Step-by-step explanation:

Find out how much newspaper he drops for 4.3 miles.

1/4 = 0.25

4.3 miles ÷ 0.25 = 17.2

= 17

17 x 22.7 = 385.9

(Newspapers be dropped a day)

1 week of dropping newspapers = 385.9 x 3 = 1157.7

1 month of dropping newspapers = 1157.7 x 4 =

4630.8

1 year = 12 months

5 years = 12 x 5 = 60 months.

5 years/60 months of dropping newspapers = 4630.8 x 60 = 277 848

Tommy dropped 277 848 newspapers.
