Well u have a basic equation y=a • b^x
a is the initial amount
b is the growth factor
and x is the exponent
the first step is to make a chart with ur two points for example
(0,4) and (2,16)
so ur chart will be
x. | y.
0. | 4
2. | 16
next you find the difference between the x side so 0 to 2 is +2
then find the difference between the y side so 4 to 16 is +12
then put it into a fraction with y over x or y/x so 12/2 then simplified 6/1 or just 6.
6 is the growth factor
and to find a u have to go on the y column and find the first number so
a is 4
x is still x because it's 0 but if it was 2 then it would be x-2 so it can cancel
so the answer would be y=4 • 6^x
Answer:
A) True
Step-by-step explanation:
In an experiment that has the purpose of testing the efficacy of a procedure or drug, comparison is made against the efficacy of a placebo, a procedure or drug that is <em>intended to have no effect whatever</em>.
__
Famously, a placebo is often found to be nearly as effective (or even more effective) than the procedure or drug on trial. This effect is known as "the placebo effect."
Yes yes yes yes yes yes yes yes
Answer:
4200 with 35% markdown: 2730
5000 with 44% markdown: 2800
Step-by-step explanation:
To calculate the price of an item including the markdown, multiply the original price by (1 minus markdown).
Convert the markdown percentage to decimal form before subtracting.
4200 with a 35% markdown: (35% = 0.35)
4200*(1 - 0.35)
= 4200 *(0.65)
= 2730
5000 with a 44% markdown: (44% = 0.44)
5000*(1 - 0.44)
= 5000*(0.56)
= 2800
Therefore, the sale price for $4200 with a 35% markdown is $2730, and the sale price for $5000 with a 44% markdown is $2800.
