Answer:
$205
Step-by-step explanation:
The cost of bike Sarah bought = $260
Discount coupon = $55
The cost Sarah paid for the bike =$260 - $55
Use the expression 260 + (- 55) to find how much Sarah paid for her bike:
![260+(-55)\\ \\=200+60+(-55)\\ \\=200+5+55+(-55)\ [\text{Note} 55+(-55)=0]\\ \\=200+5\\ \\=205](https://tex.z-dn.net/?f=260%2B%28-55%29%5C%5C%20%5C%5C%3D200%2B60%2B%28-55%29%5C%5C%20%5C%5C%3D200%2B5%2B55%2B%28-55%29%5C%20%5B%5Ctext%7BNote%7D%2055%2B%28-55%29%3D0%5D%5C%5C%20%5C%5C%3D200%2B5%5C%5C%20%5C%5C%3D205)
So, Sarah paid $205 for the bike.

Answer:
option b
1.5
Step-by-step explanation:
Given in the question an equation,
y = 1.5sin4x
The amplitude of y=asin(x) represents half the distance between the maximum and minimum values of the function.
Amplitude = |a|
In the equation y = 1.5sin4x, a = 1.5
So, amplitude of graph y = 1.5sin4x = 1.5
Answer:
Stratified Sampling
Step-by-step explanation:
1)Since Professor Hardtack divided the population according to a specified characteristic then this is a stratified sampling. Notice that a criteria other than geographical has been used by Mr. Hardtack to make it.

Answer:
Step-by-step explanation:
143 = 100 + 4 0 + 3
5*(143) = 5 * (100 + 40 + 3)
= 5*100 + 5*40 +5*3
= 500 + 200 + 15
= 715
