Keiko has 5 options to choose from for her favorite band. For each of those 5, she can choose from the remaining 4 for her second favorite, and for each of those 4, she can choose from the remaining 3 for her third favorite. Altogether, this gives her 5 x 4 x 3  = 60 different votes that she could potentially make.

Before tax & after a 50%
Slav-nsk [51]

Answer: The boots were marked $86.

Step-by-step explanation: We know Mica's total was $100 for the bill. He got the only hat left marked $12, and a pair of boots. Before tax and after a 50% sale, her total is $100. Since she spent $12 for the hat, we know the rest of the money is going towards the boots. The boots will cost $86.

Hat($12) + Boots($86) = 100

How to solve it with walk through steps
mario62 [17]
You can say

x+y=5
x=5-y

You know the value of x, put it into the next equation.

3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y

Put y value back into either equation to find value of x.

x+y=5
x-2/5=5
x=5+2/5
x=27/5

Therefore, x,y = (27/5, -2/5)

Hope I helped :)

Shannon saves 1235 in november. In november, she saved $250 less than she did in december. How much money did she save in the tw
madam [21]
In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.

bulgar [2K]

Answer:

The area of the shaded region is 0.2898.

Step-by-step explanation:

Let <em>X</em> represent the IQ scores of adults.

It is provided that X\sim N(100,15^{2}).

Compute the probability of an adult having an IQ between 106 and 124 as follows:

P(106

                             =P(0.40

*Use a <em>z</em>-table.

Thus, the area of the shaded region is 0.2898.
