All of the values are represented correctly on the histogram. It represents both the points and the frequencies in the correct way.
Answer:

Step-by-step explanation:
We will use the co-function identity for sine, where:

Since sin(21)=0.358=cos(x). This means that:

Solve for x. Add x to both sides:

Subtract 21 from both sides:

Hence:

Answer: 23.75
Step-by-step explanation:
475*.05=23.75
<span>(2x^5+x^3−3x^4−x+8)−(7x^5+2x^4−12+6x−5x^3+x^2)
= </span>2x^5 − 3x^4 + x^3 −x + 8 − 7x^5 - 2x^4 + 5x^3 − x^2 − 6x + 12
= − 5x^5 − 5x^4 + 6x^3 − x^2 − 7x + 20
