based on the number of marbles in the bag, the number of marble groups possible is 7,140 groups.

the probability of selecting 2 red and 1 yellow is 1/68.

<h3>what number of 3-marble groups can be made?</h3>

first, find the number of marbles:

= 7 + 8 + 9 + 7 + 5

= 36

the number of marble groups are:

= 36 ! / (3 ! x 33 !)

= 7,140 groups

the probability of picking 2 red and 1 yellow is:

= (( (7! / (2! x 5!)) x ( ( 5! / (1! x 4!))) / 7,140

= 1 / 68

= 1.47%

A customer works into a post office to purchase stamps. she purchases a total of 45 stamps. some of the stamps are 49cent stamps

baherus [9]

Step-by-step explanation:Let number of 49 cents =A

Let number of 33 cents=B

A+B=45 equation 1

1 $=100 cents

49 cents =.49 dollar

33 cents=.33 dollar

so .49A+.33B=17.89 equation 2

Add equation 1 and equation 2

since these are simultaneous equations

.49A+.33B=17.89

A+ B=45

so divide equation 2 by 100 we get

49A+33B=1789

A+B =45 multiply equation 1 by 33 on both the sides we get

33A+33B=1485 equation 3

so subtract equation 3 from equation 2 we get

49A+33B=1789 equation 2

33A+33B=1485 equation 3

16A+0 =304

16A=304

A=304/16

A=19

putting nalue of A in equation 1 we get

A+B=45

19+B=45

B=45-19

B=26

so number of 49 cent stamps are 19

and number of 33 cent stamps are 26

deff fn [24]

The distance between the 2 locations = 7 units

Step-by-step explanation:

Step 1:

Given,

Location of Hot dogs = (6,4)

Location of Mustard = (6,-3)

We need to find the distance between the two locations

Step 2:

Since the x coordinates of both the location are the same , they lie in the same line.

The first location is 4 units above the x axis and the second location is 3 units below the x axis.

Hence the distance between the 2 locations 4-(-3) = 7 units

Step 3 :

Answer :

The distance between the 2 locations = 7 units
