Answer:
c. infinite solutions
Step-by-step explanation:
y = 10x + 2
This is a line. A line has infinite points
Therefore this has infinite solutions
Average=(total number)/(number of items)
given that the final exam counts as two test, let the final exam be x. The weight of the final exams on the average is 2, thus the final exam can be written as 2x because any score Shureka gets will be doubled before the averaging.
Hence our inequality will be as follows:
(67+68+76+63+2x)/6≥71
(274+2x)/6≥71
solving the above we get:
274+2x≥71×6
274+2x≥426
2x≥426-274
2x≥152
x≥76
b] The above answer is x≥76, the mean of this is that if Shureka is aiming at getting an average of 71 or above, then she should be able to get a minimum score of 76 or above. Anything less than 76 will drop her average lower than 71.
Answer:
5x I believe
Step-by-step explanation:
it rises by 5 each time
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
Answer:
(a) $12,000. It is reasonable since profit is positive
(b) $6,000
Step-by-step explanation:
(a) The promoter's expected profit is given by the product of his potential earnings by the probability that it does not rain, minus the product of his potential losses by the probability of rain:

The promoter's expected profit is $12,000, it is a reasonable criterion since profit is positive.
(b) An insurance company should charge the product of the full potential losses by the probability of rain:

An insurance company should charge $6,000.
