Answer:

Invalid statement: There is exactly 1 yellow marble in the box

Step-by-step explanation:

The probability of finding a yellow marble is Py = 1/30, according to the sample. Then, the number of yellow marbles expected to find in the box is:

N x Py > 1 ,

where N = 250 (number of marbles in the box).

Thus, we expect to find more than one yellow marble in the box and the Invalid statement is: "There is exactly 1 yellow marble in the box".

Abdull sells computers for a local computer outlet. He gets paid $400 per month plus a commission of 4.2% on all the computer ha

Fed [463]

Ok. So… Let's see if I can solve this one.

So since they wanted 4.2% out of the 640,000 Abdull makes, we can move the decimal(4.2%) to the left twice. Which will get .042 . The afterword-that will allow us to multiply 640,000 dollar with .042 . Which mean Adbull has receive 26,880 cash that year.

Answer for “A” = 26,880

Ok so his annual salary plus his commission. That means his 400 dollar (per month) plus the amount on the sales commission. Which mean… 400 dollar(Monthly) plus 26,880 dollars. Which will get us 27,280

A = 26,880

B = 27,280

(Im not sure about answer B because Im not sure if they are talking about yearly price for both or monthly payment for 400 dollar plus the monthly commission.) But overall, their,you have your answer.

15. The dollar amount y that remains to be repaid on a loan x months after the loan is issued is represented by y=-1000x + 8000.

irina [24]

Answer:

1) $8000

2) $1000

3) 8 months, since y represents our remaining amount to be paid, we set it equal to 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.

Step-by-step explanation:

We have the equation y = -1000x + 8000 which follows the linear equation:

y = mx + b, where m is our slope and b is our y-intercept

1) The initial balance can be found with our constant "b" which in this case is 8000. You can also plot the function of y and you will find that 8000 is the intercept when x = 0, aka the start

2) We can calculate the rate of change for when the loan is repaid by looking at the slope "m", in this case it is 1000. It subtracts 1000 each month, meaning $1000 is being payed and taken out of the bank account

3) To find how many months it will take for the loan to be repaid, let's solve for x when y = 0.

0 = -1000x + 8000

-8000 = -1000x

8 = x

It will take 8 months. Why? Since y represents our remaining amount to be paid, we set it = 0, to see when $0 need to be paid. Solving for x (months), we can it to be 8.

The average length of an adult eastern coach whip snake is 152.4 centimeters write a sentence comparing its length to the other

crimeas [40]

Answer:

The eastern coach whip snake is:

i. 88.9 cm longer than the Copperhead snake

ii. 88.9 cm longer than the Western cottonmouth snake

iii. 30.8 cm longer than the Timber rattlesnake

iv. 91.4 cm longer than the Queen snake

Step-by-step explanation:

The average length of the adult eastern coach whip snake is 152.4 centimeters.

The length of the Copperhead snake is 63.5 centimeters

The difference between 152.4 and 63.5 is 152.4-63.5=88.9

Therefore the eastern coach whip snake is 88.9 cm longer than the Copperhead snake

The Western cottonmouth is 63.5 cm just the same length as the copperhead snake.

Hence, the eastern coach whip snake is also 88.9 cm longer than the Western cottonmouth snake

The Timber rattlesnake is 121.6 cm long. Since 152.4-121.6=30.8, the eastern coach whip snake is 30.8 cm longer than the Timber rattlesnake

Also, 154.2-61=91.4

Therefore the eastern coach whip snake is 91.4 cm longer than the Queen snake.
