if Timothy uses 20 inches of yarn for knitting yard every 5 minutes, then we can divide the total time in this time so in 1 hour are 60 minutues so:
Then he has to use:
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Rule: Always simplify the innermost bracket first.
- Given expression: 35 - {15 - (19 + 5)} ÷ 3
<u>Solution:</u>
- 35 - {15 - (19 + 5)} ÷ 3
- => 35 - {15 - (24)} ÷ 3
- => 35 - {15 - 24} ÷ 3
- => 35 - {-9} ÷ 3
- => 35 + 9 ÷ 3
- => 35 + 3
- => 38
Hence, the simplified answer is 38.
Answer: mean of sampling distribution of means = 18.6
Step-by-step explanation:
In sampling theory, the population mean is expected to equal to the mean of sampling distribution of means if the estimator is to be a good representative of the population. so, on this note, the mean of sample distribution of means is equal to the population mean = 18.6
sin (x) = -1
arcsin (-1) = x
x = -90
and multiples of 360
x =-90, 270,....
x =-90 + 360n where n is an integer
or in radians
-pi/2 + 2*pi *n where n is an integer
