To find 50 percent, you multiply the number by 0.5 (for 30%, 0.3 etc.).
42.88 * 0.5 = 21.44
Answer:
C. -3/2
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
We know that line <em>m </em>is perpendicular to line <em>l. </em>
Line <em>l </em>has a slope of 2/3. To find the slope of line <em>m, </em>find the negative reciprocal of 2/3.
Negative: switch the sign
2/3 --> -2/3
Reciprocal: switch the numerator (top number) and denominator (bottom number)
-2/3 --> -3/2
Line <em>m</em> has a slope of -3/2 and C is correct.
Answer: 1.48
Step-by-step explanation:
Answer: 0.2643
Step-by-step explanation:
Given : The proportion of adults are unemployed : p=0.077
The sample size = 300
By suing normal approximation to the binomial , we have
Now, using formula 
, the z-value corresponding to 26 will be :-
Using standard distribution table for z , we have
P-value=
Hence, the probability that at least 26 in the sample are unemployed =0.2643
Answer: a. Area b. 4222.26
