Day 2: 14 is 47% and 16 is 53%

Day 3: 13 is 43% and 17 is 57%

as for the second question, the reason why it's different for each day is probability, the probability can change with literally every movement like how hard you fling it or if there's outside interference like the wind.

Jack and Diane were saving money to go to a rock n roll concert. They need at least $750 in order to go if you count their gas,

nataly862011 [7]

Answer:

$\left\{\begin{array}{l}y\le 4x\\ \\x\ge 10\\ \\50x+25y\ge 750\end{array}\right.$

Step-by-step explanation:

Let x represents the number of nights Jack worked and y represents the number of nights Diane worked.

1. The number of nights Diane is scheduled to work is no more than four times the number of nights Jack is scheduled to play. Then

$y\le 4x$

2. Diane will work at least 10 times before the concert. Then

$x\ge 10$

3. Jack earns $50 per night that he plays, then he earned $50x in x nights. Diane earns $25 each night she works, then she earns $25y in y nigths. They need at least $750, so

$50x+25y\ge 750$

4. We get the following set of constraints to model the problem:

$\left\{\begin{array}{l}y\le 4x\\ \\x\ge 10\\ \\50x+25y\ge 750\end{array}\right.$

Sam wants to leave an 18% tip for his dinner. The bill is for $23.50.

vlabodo [156]

Divide the % of tax u want to leave by 100 then multiply that by the total. that will give u the $ of tax. if u add that on to the sub total that will give u the final total.

Example:
18/100= .18
.18x$23.50= $4.23 (this is the tax in $
$23.50+$4.23= $27.73
