It takes Joey 1/16 of an hour to write one Thank You card. How many cards can he write in 3/4 of an hour?

Naddik [55]

The answer would be 12 cards. If you convert 3/4 into 12/16, it tells you automatically that Joey made 12 cards, since it takes him 1/16 of an hour to write one.
Hope this helps!

You flip a coin four times and then roll a fair six sided die four times. The coin lands heads up every time in the day shows an

exis [7]

Answer:

0.00390625

Step-by-step explanation:

For coins :

Number of rolls, trials, n = 4

P(heads) = 0.5

Using binomial probability formula :

P(x =x) : nCr * p^x q ;

P(obtaining exactly 4 heads) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625

P(even number from 4 coin tosses)

Even faces = (2,4,6)

Total faces = (1,2,3,4,5,6)

P(success) = 3/6 = 0.5

P(obtaining exactly 4 even) = 4C4 * 0.5^4 * 0.5^0 = 1 * 0. 0625 * 1 = 0.0625

Hence, obtaining 4 even outcomes and 4 heads = 0.0625 * 0.0625 =0.00390625

Melissa put her cat, Herman, on a diet and kept track of his weight. At the end of 4 weeks, she recorded Herman's weight change

Sergio [31]

The cats weight change each week is $-1\frac{1}{8}$ ounces

<h3><u>Solution:</u></h3>

Given that, Melissa put her cat, Herman, on a diet and kept track of his weight.

At the end of 4 weeks, she recorded Herman's weight change as $-4\frac{1}{2}$ ounces.

She noticed that he had lost the same amount of weight each week.

We have to find what is Herman's weight change each week of the diet?

Now, let the weight lost per week be n ounces.

Then, in total he lost 4n ounces in 4 weeks

And we are given that, lost wait is $-4\frac{1}{2}$ ounces

$\begin{array}{l}{4 n=-(4 \frac{1}{2}) \text { ounces }} \\\\ {4 n=-(\frac{4 \times 2+1}{2})} \\\\ {4 n=-(\frac{9}{2})} \\\\ {n=-(\frac{9}{8})=-(\frac{8+1}{8})=-1 \frac{1}{8} \text { ounces }}\end{array}$

Here negative sign indicates cat is losing weight

Hence, the cats weight change each week is $-1\frac{1}{8}$ ounces
