strojnjashka [21]

Answer:

He does not have enough money left to buy a backpack for $37.50

Step-by-step explanation:

If he spent 40% of $60 on take out food, that means he spent $24.

So the remaining money would be $60-$24=$36.

So, no, he does not have enough money left to buy a backpack for $37.50

Cars arriving for gasoline at a Shell station follow a Poisson distribution with a mean of 9 per hour. A. Determine the probabil

german

Answer:

Step-by-step explanation:

Given

Poisson Distribution with mean of 9 per hour

Mean of Process $=\lambda t$

Probability that over the next hour , only one car will arrive

Probability is given by

$P\left ( x\left ( t \right )=k\right )=\frac{e^{-\lambda t}\left ( \lambda t\right )^k}{k!}$

For k=1 and t=1

$P\left ( x\left ( 1\right )=1\right )=\frac{e^{-\lambda 1}\left ( \lambda \cdot 1\right )^1}{1!}$

$P\left ( x\left ( 1\right )=1\right )=\frac{e^{9\cdot 1}\left ( \lambda \cdot 1\right )^1}{1!}=0.0011$

(b) For next 6 hours , more than 22 cars will arrive will be given by

$\lambda =9$

$\lambda \times t=9\times 6=54$

k=22, t=6 hr

$P\left ( x\left ( 4\right )> 22\right )=1-P\left ( x\left ( 4\right )\leq 22\right )$

$=1-\sum_{k=22}^{k=0}\frac{e^{54}\left ( 54\right )^k}{k!}$

Determine which choice best shows the distributive property of multiplication.

WITCHER [35]

Answer:

c) 6× (9+8) = (6 × 9) + (6× 8)

Step-by-step explanation:

<u><em>Distributive property of multiplication</em></u>

The distributive property of multiplication

a(b+c) = a b + a c

(a+b)c = ac + bc

6× (9+8) = (6× 9) + (6×8)

Steven bought a new computer at the end of a sale. The price of the computer was $52 on the day he bought it. The next day it ha

den301095 [7]

Answer:

$72.80

Step-by-step explanation:

You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.

(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)
