Answer:
An experimental study
Step-by-step explanation:
An experiment deliberately imposes some treatment on individuals in order to observe their responses.
An experimental studies formulates some conditions in order to make an inference. An observational study tries to gather information without disturbing the scene they are observing.
This is then an experiment because people are deliberately asked to taste two muffins and asked for their response.
The value of x from the given expression is 0.7558
<h3>Solving exponential equations</h3>
The standard exponential equation is expressed as y = ab^x
Given the equation below
10^x +5 = 60
Subtract 5 from both sides
10^x = 60 - 5
10^x = 55
Take the log of both sides
log10^x = log55
x = log55/log10
x = 0.7558
Hence the value of x from the given expression is 0.7558

AC=28cm BC=9cm, because AC=2xAB and BC=AC/2
Answer:
a) Angle XBC = 55° because it's a corresponding angle
AXY = XBC
b) 180° - (55° × 2) = 70°
