Answer:
3. Jonathon does 2 push-ups for every 15 crunches.
Step-by-step explanation:
Hope it helps
Each of these roots can be expressed as a binomial:
(x+1)=0, which solves to -1
(x-3)=0, which solves to 3
(x-3i)=0 which solves to 3i
(x+3i)=0, which solves to -3i
There are four roots, so our final equation will have x^4 as the least degree
Multiply them together. I'll multiply the i binomials first:
(x-3i)(x+3i) = x²+3ix-3ix-9i²
x²-9i²
x²+9 [since i²=-1]
Now I'll multiply the first two binomials together:
(x+1)(x-3) = x²-3x+x-3
x²-2x-3
Lastly, we'll multiply the two derived terms together:
(x²+9)(x²-2x-3) [from the binomial, I'll distribute the first term, then the second term, and I'll stack them so we can simply add like terms together]
x^4 -2x³-3x²
<u> +9x²-18x-27</u>
x^4-2x³+6x²-18x-27
Its when x+-1 because thats when f of x or f(x) is highest
Answer:
5/9
Step-by-step explanation:
From the information, 8 are more than 6 feet tall and 7 have good aim.
Therefore, the probability that the coach would randomly pick a player over 6 feet tall or a player with a good aim will be:
= 8/27 + 7/27
= 15/27
= 5/9
*see attachment for the diagram of the two box plots referred to here.
Answer:
2 inches
Step-by-step explanation:
The median of a box plot is the data value that lies exactly where the vertical line divides the box into two.
Therefore:
Median for Class 1 = 17 inches
Median for class 2 = 15 inches
The difference in the medians of both box plots = 17 - 15 = 2 inches
