Answer:
300
Step-by-step explanation:
Note the hundreds place value (bolded and underlined)
<u>2</u>87
Look at the place value directly next to it (the tens place value). It is an 8. Because 8 is greater than 5, round up:
287 rounded to the nearest hundreds is 300.
300 is your answer.

Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
- f(4)= 3*4-4²= -4 ⇒ correct
- f(3)= 3*3-3²= 0 ⇒ correct
- f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
- f(0) = 3*0-0²= 0 ⇒ incorrect
- f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct

He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Order set...{160,165,170,240,240,450}
The "mean" is the arithmetic average of the elements...
mean=(160+165+170+240+240+450)/6=237.5
The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.
In this case the number of elements is even and the middle two terms are 170 and 240 so:
median=(170+240)/2=205
The "mode" is the term which appears the most in the set, so in this case:
mode=240
