Answer:
352.
y = 8c + 16d
Step-by-step explanation:
Expression:
c = cats
d = dogs
Expresion: y = 8c + 16d
Now use it by plugging in.
y = 8c + 16d
y = 8(16) + 16(14)
y = 128 + 224
y = 352 (that's how much he earned)
Answer:

Step-by-step explanation:
Answer: ( 1.25, 1.55)
Therefore at 95% confidence interval (a,b) = ( 1.25, 1.55)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean gain x = 1.4
Standard deviation r = 0.5
Number of samples n = 42
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
1.4+/-1.96(0.5/√42)
1.4+/-1.96(0.0772)
1.4+/-0.1512
1.4+/-0.15
= ( 1.25, 1.55)
Therefore at 95% confidence interval (a,b) = ( 1.25, 1.55)
