You start by subtract 250 from 500 then take 15% of 250 and you get 37.5 so you end up having 12.5 in the checking account

Answer:

$187.50

Step-by-step explanation: She starts out with $500  dollars and then she gives 250 of it to her brother and therefore she is $250 left. Then she takes 15% of her remaining money which would be $37.50 and puts it in her savings account leaving Amanda with $212.50 in her checking account. After that she spends $25 on an outfit for the party which means that she would end up with $187.50 in her checking account.

Joe and Brody order some food for their families. Joe orders 2 chicken dinners and 3 sides for $34.50. Brody
Lerok [7]

Answer: D

Step-by-step explanation:

If Joe orders 2 chicken dinners and 3 sides for $34.50, then you have to multiply 3.50 by 3 to get the ammount that the dinners cost.

3.50x3 = 10.50

Next, you have to subtract 10.50 from 34.50 to get the cost of just the 2 dinners.

34.50 - 10.50 = 24.00

Now, divide 24 by 2 to get the cost for 1 dinner.

24/2 = 12

Since Brody ordered 2 sides, you have to subtract 3.50x2 = 7 from 43 to get the total of his dinners.

43 - 7 = 36.

Now we can check our answer. Since 1 dinner costs $12, we can multiply 12 by 3 to get 36, which is the exact same number as the one we just figured out. So, each side costs 3.50.

(You can also multiply 12 by 3.50 to get 43, which was the total cost of Brody's order.)

Jim has calculated the area of a rectangle to be x^3 + x^2 + x + 1. If the width of the rectangle is x + 1, then its length is
Lady_Fox [76]
A = <span>x^3 + x^2 + x + 1
A = x^2(x +1) + (x+1)
A = (X + 1)(x^2 + 1)

W =  x +1
so L = x^2 + 1 because A = L*W

A pond contains 110 fish, of which 20 are carp. If 10 fish are caught from the lake, what are the mean and variance of the numbe
Varvara68 [4.7K]

Answer:

Mean = 1.82

Variance = 1.365

Step-by-step explanation:

We define X as the random variable that counts the number of the carp fishes that has been caught. Also we assume that all the fishes are equally likely to be caught. In that case we have that X as hypergeometric distribution.

The of the Hypergeometric Distribution and Its variance is given below.

Mean of the distribution = n*\frac{k}{N}

Variance = \frac{n*k*(N-k)(N-n)}{N^2(N-1)}

N= 110

k = 20

n = 10

Upon calculation we get

Mean = 10*\frac{20}{110}

          = 1.82

Variance = \frac{10*20*(110-20)(110-10)}{110*110*(110-1)} = 2*90*100/11*11*109 = 1.365

Therefore the mean is 1.82 and variance is 1.365

10th grade Geometry. -5(7w + 8) = 30
borishaifa [10]

the required equation will be:

-5( 7w+ 8)= 30

-35w- 40= 30

-35w= 30+ 40( as 40 is taken to the other side, its symbol changes)

-35w= 70

W= 70/-35

W= -2
