Brittany removed half of the total number of marbles from her bag, and gave one fourth of the remaining marbles to her friend. W
patriot [66]

The fraction of the total number of marbles is left in the bag after removing and giving part to her friend is 3/8

<h3>Fraction</h3>

let

  • Number of marbles in her bag = x
  • Number of marbles removed from her bag = 1/2x

Remaining marbles = x - 1/2x

= (2x-x) / 2

= x/2

= 1/2x

Number of marbles given to her friend = 1/4 of 1/2x

= 1/4 × 1/2x

= 1/8x

Number of marbles left in the bag = Remaining marbles - Number of marbles given to her friend

= 1/2x - 1/8x

= (4x-x) / 8

= 3x/8

= 3/8x

RUDIKE [14]
X=small bag
y=large bag

5x+3y=260
4x+2y=200

(5x+3y=260)*4 =20x+12y=1040
(4x+2y=200)*5 =20x+10y=1000

subtract two equations: 2y=40
divide:                           y=20
plug y in                         5x+3*20=260
simplify                         x=40

small bag=$40
large bag=$20

Naya [18.7K]

Answer:

(0.55525, 1.24475)

Step-by-step explanation:

Given that to save money, a local charity organization wants to target its mailing requests for donations to individuals who are most supportive of its cause.

                     Men    women

Sample size      5        5

Mean rate        6.2     5.3

Mean diffference = 6.2-5.3=0.9

Std error for difference = 0.25 (given)

Since we have two groups and also sample sizes are very small we can use t significant value for finding out confidence interval

df = 5+5-2 =8

t critical value for 80% two tailed = 1.397

Conf interval 80%

=(0.9-1.397*0.25, 0.9+1.397*0.25)\\= (0.55525, 1.24475)
