There are 20 cups and each one holds 10 fluid ounces. Assuming that she wants to fill them all up to the brim and use the complete 10 fluid ounces for each cup this means she would have a total of 200 fluid ounces: 20 * 10 = 200

1 gallon = 4 quarts

1 quart = 32 fluid ounces

This means that for every gallon she has 128 fluid ounces: 1 gallon (4 quarts/1gallon)(32 fluid ounces/1 quart) = 128

This means she needs at least 200 fluid ounces and she must buy another gallon to satisfy this; 128 * 2 = 256 fluid ounces.

She needs to buy 2 gallons but will have an extra 56 fluid ounces

Answer:

The smallest sample size to satisfy the conditions is n=500.

Step-by-step explanation:

The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

$np\geq10\\\\n(1-p)\geq10$

The largest sample size required will be for the minimum p or (1-p).

This happens to be the proportion that can play other instruments: 2%.

Then, we can calculate the minimum sample size as:

$np\geq10\\\\n(0.02)\geq10\\\\n\geq(10/0.02)\\\\n\geq500$

Solve for the value of p<br><br>dont ask for ang information cuz that is literally all it says

seraphim [82]

Answer:

p = 35

Step-by-step explanation:

( 2p + 5 ) + ( 3p ) = 180

2p+5+3p=180

Combine 2p and 3p to get 5p.

5p+5=180

Subtract 5 from both sides.

5p=180−5

Subtract 5 from 180 to get 175.

5p=175

Divide both sides by 5.

p = 175\5

Divide 175 by 5 to get 35.

p = 35
