= 3^3
Answer:
Step-by-step explanation:
first solve for y=mx+ b format
y-3= 1/2(x+2)
y-3= 1/2x+1
y= 1/2x+4
slope is 1/2; y-intercept is 4
Answer:
the answer is d

It is true that the confidence intervals for the mean provide an estimate for where the true mean lies.
In statistics, a confidence interval denotes the likelihood that a population parameter will fall between a set of values for a given proportion of the time. A confidence interval depicts the likelihood that a parameter will fall between two values near the mean. Confidence intervals quantify the degree of uncertainty or certainty in a sampling procedure.
The mean is a basic mathematical average of two or more values. There are two sorts of means that may be calculated: the arithmetic mean and the geometric mean. A mean tells you the average of a bunch of values, which helps you contextualize each data point.

X+y=29.8
Y=29.8-x so
1.45x+1.55(29.8-x)=20 then solve for x
1.45x+46.19-1.55x=20
-0.1x=20-46.19
-0.1x=−26.19
X=26.19/0.1
X=261.9
Y=29.8-261.9
Y=−232
