Break down $750. Where the first $500 is charged 1.5% and the remaining $250 is charged 1%
$500 * 1.5% = $7.50
$250 * 1.0% = $2.50
The total charge for the unpaid amount of $750 is $10.00
Answer: choice B
Step-by-step explanation:
The graph of y=-3x^n is the reflection of the graph of y=3x^n about the x-axis.
Using the chord theorem, <u>option C</u> is the best solution since <u>x = 5</u>.
The four line segments that are created by two intersecting chords inside of a circle are explained by the chord theorem, sometimes referred to as the intersecting chords theorem, a statement in fundamental geometry. The products of the line segment lengths on each chord are equal, according to this assertion.
The value of x must be determined in order to answer the question.
We may determine the following using the chord property:
8*x = 4*10,
or, 8x = 40,
or, x = 40/8,
or x = 5.
Given that x = 5, option C is the best option according to the chord theorem.

Answer:
(228.663 ; 241.337)
Step-by-step explanation:
Given that:
Mean (m) = 235
Standard deviation (s) = 28
α = 95%
Zcritical at 95% = 1.96
Sample size (n) = 75
The confidence interval of the population mean can be obtained using the relation :
Mean ± Error
Error = Zcritical * (s/sqrt(n))
Error = 1.96 * (28/sqrt(75))
Error = 1.96 * 3.2331615
Error = 6.33699654
Error = 6.337
Lower boundary = 235 - 6.337 = 228.663
Upper boundary = 235 + 6.337 = 241.337
(228.663 ; 241.337)
