Answer:
7) is 625
8) 169
9) 1.44
10) 180??
11) 1000000
12) 3430
hopefully these are right
Step-by-step explanation:
Answer: No
Step-by-step explanation:
1/8 = 0.125, while 3/4 is 0.75, therefore 1/8 is not greater than 3/4
Answer:
(a) 3, 5 and 6
Step-by-step explanation:
In the experiment, 43 are to be given a gel that contains the tooth-whitening chemicals while the remaining 42 are to be given a placebo. Therefore, a placebo is used.
The 43 that will receive the gel are to be selected randomly.
After the experiment, the whiteness of the two groups will be compared to see the effect of the gel.
Therefore for the experiment to be completely random, 3, 5, and 6 apply.
(b)
For the experiment to be double-blind, the researchers who will evaluate the whiteness and interact with the subjects, and the subjects would not know which subjects received either the whitening gel or the placebo.
Answer:
Step-by-step explanation:
hello :
it the width and length the Integer number you have two rectangle :
22 = 1×22 or 22 = 2×11
1) width = 1 length =22
2) width =2 length =11
Answer:
x = 61
Step-by-step explanation:
Formula:
(N {which is the number of sides in the polygon] - 2) * 180 = the sum of all the angles in the polygon.
Simply add the known angles together, subtract that from the above equation and you get the value of x.
(5 {which is N] - 2) * 180
3 * 180 = 540
82 + 121 + 129 + 147 = 479
540 - 479 = x
540 - 479 - 61
x = 61
