Slope of EF = 5/2
Slope of XY=4/3
Further explanation:
"Slope is the steepness of a line"
The formula for slope when two lines are given:
Now,
<u>1. E(2-1) and F(4,4)</u>
<u>2. X(1, 4) and Y(-2,0)</u>
Hence,
Slope of EF = 5/2
Slope of XY=4/3

Answer:
The answer is C I believe.
Step-by-step explanation:
Answer:
Step-by-step explanation:
We would apply the law of Cosines which is expressed as
a² = b² + c² - 2abCosA
Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes
JK² = JL² + KL² - 2(JL × KL)Cos10
JK² = 61² + 53² - 2(61 × 53)Cos10
JK² = 3721 + 2809 - 6466Cos10
JK² = 6530 - 6367.767
JK² = 162.233
Taking square root of both sides of the equation, it becomes
JK = √162.233
JK = 12.73 to the nearest tenth
Answer:
The standard error of the sample mean is 0.57
Step-by-step explanation:
we know that
The Standard Error Formula is given by the formula
where:
SE = standard error
s = standard deviation
n = the sample size
In this problem we have
substitute in the formula
