A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price o
Kitty [74]

Answer:

a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.

b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:

315/x = 70/100

This is because 315 is part of the whole and is 70% of the value of x.

Step-by-step explanation:

Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.

Find the volume of the prism at right all angles are right angles.....
dexar [7]
Lets divide this prism into two parts. The bottom part has dimensions of 15mm length x 5mm width x 7mm height.

The bottom is 15x5x7 = 525 cubic mm.

The top part has dimensions of 9mm length (I got this by subtracting the 3mm on each side that the top is shorter than the bottom.. 15-3x2) x 5mm width x 3mm height.

The top is 9x5x3 = 135 cubic mm.

Added together ... 525 + 135 = 660 cubic mm = the total area of the prism.

Hope this helps

Suppose a six-sided die is tossed 1200 times and a 6 comes up 419 times. (a) Find the empirical probability for a 6 to occur. (E
krok68 [10]

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

         =\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349

Probability = 0.349

b) Theoretical Probability:

                     =\frac{1}{6}

Here both probabilities are not equal.

Therefore the die is not fair and biased.
