Answer:
$9.90 per hour
Step-by-step explanation:
This month:
Initial pay: $10 per hour
% raise : 10%
Dollar amount of raise = 10% x $10
= 10/100 x 10 = $1
Gina's pay after the raise = $10 + $1 = $11 per hour
Next Month:
Starting pay: $11 per hour
% decrease : 10%
Dollar amount of decrease = 10% x $11
= 10/100 x 11 = $1.10
Gina's pay after decrease = $11 - 1.10 = $9.90 per hour
Answer:
We conlude that it is cluster random sample.
Step-by-step explanation:
We know that:
The buyer for an electronics store wants to estimate the proportion of defective wireless game controllers in a shipment of 5,000 controllers from the store's primary supplier. The shipment consists of 200 boxes each containing 25 controllers. The buyer numbers the boxes from 1 to 200 and randomly selects six numbers in that range. She then opens the six boxes with the corresponding numbers, examines all 25 controllers in each of these boxes, and determines the proportion of the 150 controllers that are defective.
We conlude that it is cluster random sample.

Answer:
Amplitude increases and the period decreases
Step-by-step explanation:
Here, we are to compare amplitude change and period change
The first equation is;
y = sin x
The second is
y = 3 sine (2/3)x
Generally, the equation of a sine graph can be written as;
y = a sin (bx + c)
where a represents the amplitude and b refers to the period
In the first equation , a = 1 while in the second , a = 3 ; This shows an amplitude increase
In the first equation, b = 1 while in the second equation b = 2/3; this shows a period decrease
