Answer:
The inverse represents the temperature F corresponding to a temperature C.
The domain of the inverse function is all real numbers.
194°F
Step-by-step explanation:
Let C= y
y= 5/9 (F - 32),
F= 9/5y + 32
But y= C, hence;
F= 9/5 C +32
The inverse represents the temperature F corresponding to a temperature C.
Given;
F= 9/5 C +32
The domain of the inverse function is all real numbers.
Given C= 90°
F= 9/5 C +32
F= 9/5 (90°) +32
F= 194°F
Answer:
The value of the test statistic is 2.8.
Step-by-step explanation:
The test statistic is:
In which X is the sample mean, 
is the value expected value for the population mean, 
is the standard deviation and n is the size of the sample.
Sales at a fast-food restaurant average $6,000 per day
This means that 
Sample of 49
This means that 
The sample showed average daily sales of $6,400.
This means that 
Population standard deviation is about $1,000.
This means that 
The value of the test statistic is
The value of the test statistic is 2.8.
Step-by-step explanation:
11.3x-12 for x=5
=3(5)-12
=15-12
=3
12.45+15(n-1) for n=6
=45+15(6-1)
=45+15(5)
=45+75
=120
Answer:
32°
Step-by-step explanation:
The triangle ABC is a isosceles so angle A = angle C
The sum of interior angles in a triangle is = 180°
74 + 74 + angle B = 180
B = 32°
