Answer:
Answer is D. 98500 and 4000
Refer below.
Step-by-step explanation:
The average salary of a travel management professional is $98,500. Assume that the standard deviation of such salaries is $40,000. A random sample of 100 travel management professionals are selected, then the mean and standard deviation of the sampling mean is 98500 and 4000.
Answer:
y = -
x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
3x + 4y = 8 ( subtract 3x from both sides )
4y = - 3x + 8 ( divide all terms by 4 )
y = -
x + 2 ← in slope- intercept form
Answer:
121.
Step-by-step explanation:
The lowest prime number after 10 is 11.
So it must be 11^2 = 121.
Answer:
i. sin(C) = 
ii. tan(C) = 
iii. sin(B) = 
Step-by-step explanation:
Given a right angled triangle ABC, with a right angle at A.
<ABC = 
<BCA = 
AC = 9 = 1
CB = 18 = 2
Applying Pythagoras theorem to ΔABC, we have;
AB = 
= 
= 
Thus applying the trigonometric ratios, it would be observed that;
i. sin(C) = 
ii. tan(C) = 
iii. sin(B) = 
Answer:
TRUE
Step-by-step explanation:
Favorable outcomes / total outcomes = P(outcomes) or probability
