Answer:
$30341.88
Step-by-step explanation:
Because it says simple interest, use the formula I = Prt.
(I is interest, r is the % rate as a decimal, t is the time)
So, you have to solve the equation,
1755 = P (0.065)(9)
Since 0.065 x 9 = 0.585, the equation can be simplified to
1755 = 0.585P
Then, to get P, you divide both sides by 0.585
P = 1755/0.585 = $30341.88
Answer:
144
Step-by-step explanation:
54+90=144
144-90=54
90+54=144
144-54=90

The price of the computer program is 50 dollars.Since, it is on sale, the current price is now 37.50 dollars.Base on the given choices or options, let's find out which is correct.But, first let's solve this to be able to identify which one is the correct answer:=> 37.50 dollars / 50 dollars = 0.75=> 0.75 * 100% = 75%=> 100% - 75% = 25%.<span>Thus, the discount percentage is 25% and the current price is 75%.</span>
Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
