A store sells 22 bottles of water for $4. Use the ratio table to find the cost of 33 bottles.

I need help with this please help me if you are a good person

6)
91 is a composite number because it's divisible by 7 and 13

7)
477 is divisible by 3 and 9, since the sum of its digits (18) is divisible by 3 and 9 ( or the sum is a multiple of 3 and 9) .Not divisible by 6

8)
348:is divisible by 4 because the last 2 digits (48) are a multiple of 4
348:is NOT divisible by 5 because the last digit is neither 5 nor 0
348:is divisible by 6 because it's divisible by 2 and also by 3

9)
23624 is divisible by 8 because te last 3 digits (624) are divisible y 8
(624/8 =78)
None of the others are divisible by 8

10) A number is divisible by 6 IF IT'S DIVISIBLE BY 2 AND BY 3:
213 NO

468 is divisible by 2 since the last digit is divisible by 2. It's also divisible by
3 since the sum of its digits [18] is divisible by 3, hence 468 is divisible by 6

621 it's divisible by 3 but NOT by 2, then it's not divisible by 6

A lot of 25 skylight covers are received at your construction site, and before installation are subjected to an acceptance testi

8090 [49]

Answer:

If the lot has 4 defective covers out of 25 total covers, the probability of accepting the lot is P=0.98.

Step-by-step explanation:

We have a population of N=25 skylight covers, were K=4 are defective.

We sample n=5 covers, and we will accept the lot if k=2 or fewer are defective.

We will use the hypergeometric distribution to model this probabilities.

First, to be accepted, the sample can have 2, 1 or 0 defective covers, so the probability of being accepted is:

$P(accepted)=P(k\leq2)=P(k=0)+P(k=1)+P(k=2)$

The probability that there are k defective covers in the sample is:

$P(k)=\dfrac{\dbinom{k}{k}\dbinom{N-k}{n-k}}{\dbinom{N}{n}}$

Then, we can calculate the individual probabilities as:

$P(k=0)=\dfrac{\dbinom{4}{0}\cdot \dbinom{25-4}{5-0}}{\dbinom{25}{5}}=\dfrac{\dbinom{4}{0}\cdot \dbinom{21}{5}}{\dbinom{25}{5}}\\\\\\P(k=0)=\dfrac{1\cdot 20349}{53130}=0.38$

$P(k=1)=\dfrac{\dbinom{4}{1}\cdot \dbinom{25-4}{5-1}}{\dbinom{25}{5}}=\dfrac{\dbinom{4}{1}\cdot \dbinom{21}{4}}{\dbinom{25}{5}}\\\\\\P(k=1)=\dfrac{4\cdot 5985}{53130}=0.45$

$P(k=2)=\dfrac{\dbinom{4}{2}\cdot \dbinom{25-4}{5-2}}{\dbinom{25}{5}}=\dfrac{\dbinom{4}{2}\cdot \dbinom{21}{3}}{\dbinom{25}{5}}\\\\\\P(k=2)=\dfrac{6\cdot 1330}{53130}=0.15$

If we add this probabilities, we have:

$P(accepted)=P(k\leq2)=P(k=0)+P(k=1)+P(k=2)\\\\P(accepted)=0.38+0.45+0.15=0.98$

If the lot has 4 defective covers out of 25 total covers, the probability of accepting the lot is P=0.98.

There are 6 packages that store 30 baseball cards. What is the number of cards per package? What is the constant of proportional

vekshin1

Answer:

Option A is the correct answer.

Explanation:

There are 6 packages that store 30 baseball cards.

Number of cards in 1 package = 30/6 = 5

Let us consider a as number of packages and b as number of cards.

We have equation for number of cards,

b = 5 a

The constant of proportionality = 5

Option A is the correct answer.
