A seven is a prime number because you can't divide it. 33 is a composite number because three can go into 33.

zzz [600]

Answer:

a)

$P(X = 0) = 0.64$

$P(X = 1) = 0.11$

$P(X = 2) = 0.25$

b) 0.75 = 75% probability that he makes no more than one of the shots

Step-by-step explanation:

We have these following probabilities:

64% = 0.64 probability that he misses both shots, that is, makes none of them.

11% = 0.11 probability that he makes one shot.

25% = 0.25 probability that he makes both shots.

a. Construct the appropriate probability distribution. (Round your answers to 2 decimal places.)

Binomial probability distribution, in which P(X = x) is the probability of making x shots. So

$P(X = 0) = 0.64$

$P(X = 1) = 0.11$

$P(X = 2) = 0.25$

b. What is the probability that he makes no more than one of the shots? (Round your answer to 2 decimal places.)

$P(X \leq 1) = P(X = 0) + P(X = 1) = 0.64 + 0.11 = 0.75$

0.75 = 75% probability that he makes no more than one of the shots

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40 how much would it cost to provide coffee for the whole

N76 [4]

Answer:

It would cost <u>15600</u> to provide coffee for the whole year.

Step-by-step explanation:

Given:

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40

Now, to find the cost to provide coffee for the whole year if you're place is open 5 days a week.

So, we have the unit rate, and we have to find the cost of 1.5 cup by multiplying 0.40.

<em>1.5 cup of coffee cost </em> $1.5\times 0.40=0.60.$

<em>Thus, 1.5 cup cost 0.60.</em>

<em>If, 100 people drink 1.5 cups. </em>

<em>Then, total cost of 100 people drinking 1.5 cups of coffee = </em> $100\times 0.60=60$ <em />

<em>As, place is open 5 days a week.</em>

So, to get the cost of coffee in 5 days of a week we multiply 5 by 60:

$5\times 60\\\\=300.$

<em>Hence, the cost of coffee in a week is 300.</em>

<em>In 1 year there are 52 weeks.</em>

Now, to get the cost for the whole year we multiply 52 by 300:

$52\times 300\\\\=15600.$

Therefore, it would cost 15600 to provide coffee for the whole year.

The Coffee Spot recently served 12 pastries, including 3 bran muffins. Considering this data, how many of the next 16 pastries s

Goshia [24]

Answer:

Number of bran m muffins in 16 pastries = 4 bran muffins

Step-by-step explanation:

Given:

Total number of pastries = 12

Bran muffins (Include) = 3

Find:

Number of bran m muffins in 16 pastries.

Computation:

⇒ Ratio of bran muffins to total pastries = 3 / 12

⇒ Ratio of bran muffins to total pastries = 1 / 4

⇒ Ratio of bran muffins to total pastries = 0.25

Number of bran m muffins in 16 pastries = Number of total pastries × Ratio of bran muffins to total pastries

⇒ Number of bran m muffins in 16 pastries = 16 × 0.25

⇒ Number of bran m muffins in 16 pastries = 4 bran muffins
