Answer:
{x,y}={1,7}
Step-by-step explanation:
The terminal point represented by P(x,y), is the coordinate where a certain point lies. Given is 5pi/4 radians - this will be our angle.
Evaluate the values of x and y using sin θ and cos θ
x = cos (5pi/4)
x = -√2/2
y = sin (5pi/4)
y = -√2/2
Therefore, (x,y) is (-√2/2, -√2/2)
Q1.) A. 12
Q2.) A.
Q3.) C. A probability near 1 indicates a likely event
Q4.) D. 5
Answer:
Right or positively skewed
Step-by-step explanation:
From the median and the interquartile range we can find the first and third quartile values Q3=40.15+(4.98/2)=42.64 and Q1=37.66.
Now we have enough evidence to conclude that is Right or positively skewed
1. The mean is above the median
2. The mean is 43.70, which is above the third quartile (42.64), meaning that after the mean there's less than 30% of the data.
The evidence suggests that most of the data is concentrated at the bottom of the distribution making it right or positively skewed.
Answer:
C) 21
Step-by-step explanation:
a² + 20² = 29² Use Pythagorean Theorem to solve for a
a² + 400 = 841 Solve for the exponents
- 400 - 400 Subtract 400 from both sides
a² = 441 Take the square root of both sides
a = 21
