Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
Answer:
v > -25/p
r = -5 +7/3w
Step-by-step explanation:
-vp + 40 < 65
Subtract 40 from each side
-vp + 40 -40< 65-40
-vp < 25
Divide by -p. Remember to flip the inequality
-vp/-p > 25/-p
v > -25/p
7w - 3r =15
Subtract 7w from each side
7w -7w- 3r =15-7w
-3r = 15-7w
Divide by -3
-3r/-3 (15-7w)/-3
r = -5 +7/3w
Using it's concept, it is found that the sample mean package weight for Thursday is of 19 ounces.
<h3>What is the mean of a data-set?</h3>
The mean of a data-set is given by the <u>sum of the observations divided by the number of observations</u>.
For Thursday, the package weights in ounces are given by: {18, 19, 20, 19}.
Hence, the sample mean in ounces is of:
M = (18 + 19 + 20 + 19)/4 = 19.
