Brian's gross earnings for the week of July 8, 2019, are $1227.38. His deductions comprise 23% of his total compensation.

Sindrei [870]

Answer:

$945.08

Step-by-step explanation:

Given: Gross earning of Brian= $1227.38

Deduction= 23% of total compensation.

Now, finding the amount of deduction from Brian´s gross earning.

Amount of deduction= $\frac{23}{100} \times 1227.38$

∴ Amount of deduction= $\$ 282.2974$

Next, finding the net pay of Brian after deduction.

Net pay= $Gross\ pay - deduction$

Net pay= $1227.38 - 282.2974$

∴ Net Pay= $\$ 945.0826 \approx \$945.08$

Hence, Brian´s net pay is $945.08

3. Two balls are drawn in succession without replacement from an urn containing 4 red balls and 3 blue balls. Find the probabili

choli [55]

Answer:

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

Step-by-step explanation:

Given that :

Number of red balls = 4

Number of Blue balls = 3

Total number of balls = (4 + 3) = 7

Picking without replacement :

Number of picks = 2

1st pick is red :

Probability = (required outcome / Total possible outcomes)

USing combination formula :

nCr = n! / (n-r)! r!

Total possible outcome :

7C2 = 7! / 5!2! = 7*6 / 2 = 42 / 2 = 21

X = number of red

For red = 0;

P(x =0) = required outcome / Total possible outcomes

P(x = 0)

Required outcome : [4C0 * 3C2)]

P(x = 0) = [(4C0 * 3C2)] / 21 = (1*3)/21 = 3/21 = 1/7

P(x = 1)

Required outcome : [4C1 * 3C1)]

P(x = 1) = [(4C1 * 3C1)] / 21 = (4*3)/21 = 12/21 = 4/7

P(x = 2)

Required outcome : [4C2 * 3C0)]

P(x = 2) = [(4C2 * 3C0)] / 21 = (6*1)/21 = 6/21 = 2/7

Hence ;

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

I have some answers the these problems but I just wanna make sure there right.. PLEASE Help??

yanalaym [24]

7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21

10x-40=50
Add 40 to both sides
10x=90
X=9

4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
