Answer:
4
Step-by-step explanation:
To find the degree of the polynomial, add up the exponents of each term and select the highest sum.
Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
Answer:
Mean scores.
Step-by-step explanation:
The golf player will score in the first round, according to these scores the golf player scores can be predicted. The golf player can perform high in first round but he may score lesser in the second round due to stress or mental pressure.

Answer:
6/3
Step-by-step explanation:
our average speed can be calculated in a couple different ways
is this case lets use a weighted average of the two speeds to find the average speed.
we know that that we were only going half as fast on the way back so it would take us twice as long
so our average speed would be (1/3) * 8 + (2/3) * 4
8/3 + 8/3 = 16/3 mph
another way to look at it is
to say we covered a total distance of 4 miles (2 out and 2 back)
the first 2 miles took us 1/4 of an hour since we were going at a rate of the 8 mph
the next 2 miles took us 1/2 of an hour since we were going at a rate of 4 mph
so we covered a distance of 4 miles in a time of 3/4 of an hour
distance = speed * time
speed = distance/time
speed = 4 /(3/4)
speed = 16/3 so either way we come up with the same answer
