<h3>
Answer: Approximately 2.33</h3>
The variance is given to be 5.43
Apply the square root to the variance to get the standard deviation
s = standard deviation
v = variance
s = sqrt(v)
s = sqrt(5.43)
s = 2.330326 which is approximate
s = 2.33
I rounded to 2 decimal places as this is the number of decimal places used for the variance.
X=46
Explanation:
You just have to make 3x-28 and x+64 equal to each other and x would be 46.
m∠1=44
Explanation:
You just have to subtract the 46 that u solved earlier from 90 degree so it’s 44
Answer:
y = 2x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 
x + 1 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 2 , then
y = 2x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = 16 + c ⇒ c = 5 - 16 = - 11
y = 2x - 11 ← equation of perpendicular line
Answer:
Which is number 20?
Step-by-step explanation:
Which is number 20?
2t+3n=9 2(2)+3n=9
+5t-3n=5 (the 3n cancel out) 4+3n=9
7t=14 3n=5
t=2 n=5/3 or 1.67
