Take the 89 times 5 tests. You get 445 total score you need for an average of 89. Add 82, 89, 92, 87=350 445-350=95 They must get a 95 on next test to get the average of 89
1) The ratio of used books to all books is 6:14
2) The ratio of used books to new books is 6:8
Answer:
I most likely think it is approximately 19%
Step-by-step explanation:
Assuming you mean still receive an allowance even though they dont do chores:
Ok In all the total number of students is 21. Out of those 21, 4 still receive an allowance even though they dont do chores. This is 4/21. Now all we have to do is convert 4/21 into a percentage. To do this we have to divide 100 by 21, then times 4 by that number:
100 / 21 = >> approximately 4.76
Now 4 times 4.76 :
4 * 4.76 = >>> approximately 19.04 % . We round it to 19%.
So the answer is 19%.
Answer: C) Changing one or more properties of a sine wave in response to data.
Step-by-step explanation:
Modulation is primarily used in telecommunications sector. It the process by which data is transmitted via electrical signals. It is the process of imposing an input signal on to a wave carrier. It is the pillar of data communication that enables the use information carriers of signals that are electrical and optical. Altering the carrier/ periodic waveform results in Modulation. The amplitude frequency and phase are conveyed. There are different types of Modulation which includes: amplitude Modulation, frequency Modulation, and phase Modulation.
