Answer:
The rate of simple interest is 25.89 %
Step-by-step explanation:
Given as :
The principal = $2350
The Amount = $2500
The time period = 90 days = year = 0.2465 year
Let The rate of interest = R %
So, Interest = Amount - Principal
Or, Interest = $2500 - $2350 = $150
<u>From Simple Interest method </u>
Simple Interest =
Or, $150 =
or, $150 × 100 = $579.275 × Rate
So, Rate =
∴ Rate = 25.89 %
Hence The rate of simple interest is 25.89 % Answer

Step-by-step explanation:
The reflection across y=-x swaps the coordinates and negates both of them. The first-quadrant figure becomes a third-quadrant figure.
(x, y) ⇒ (-y, -x)
Answer:
a) 0.0202
b)The seller's claim is not correct.
c) If the seller's claim is true we cannot have individual length of 72.15 inch.
Step-by-step explanation:
In the question it is given that
population mean, μ = 72 inch
Population standard deviation, σ = 0.5 inch
Sample size, n = 47
Sample mean, x =72.15 inch
a) z score = =
= 2.0567
P(x ≥ 72.15) = P(z ≥ 2.0567) = 0.5 - 0.4798 = 0.0202
We calculated the probability with the help of standard normal table.
b) The sellers claim that the machine cuts the lumber with a mean length of 72 inch is not correct as we obtained a very low probability.
c)If we assume that the seller's claim is true that is the machine cuts the lumber into mean length of 72 inch then we cannot have an individual length 72.15.
Standard error = = 0.0729
Because it does not lie within the range of two standard errors that is (μ±2 standard error) = (71.8541,72.1458)
