Answer:
a) x = 10 + -1.5y
b) y+15
Step-by-step explanation:
a)2x+3y=10*√4
2x+3y=20
2x + 3y + -3y = 20 + -3y
2x + 0 = 20 + -3y
2x = 20 + -3y
x ÷ 2 = (20 + -3y) ÷2
x = 10 + -1.5y
b)x+2y+5*3=x+y
x+2y+15=x+y
x+2y+15 - y=x+y - y
x+y+15 =x
x+y+15 - x =x - x
y+15
The sample mean of the random sample is 50
The margin of error (E) is the amount of error allowed in the random sample.
The confidence interval (CI) is given by:
CI = μ ± E = (μ - E, μ + E)
Given a confidence interval of (38.02, 61.98), hence:
μ - E = 38.02 (1)
μ + E = 61.98 (2)
Hence solving equations 1 and 2 simultaneously gives:
μ = 50, E = 11.98
Hence the sample mean of the random sample is 50

Answer:
A
Step-by-step explanation:
The answer would be the following: f(x)=5^x
No,
A line is considered a "line segment" when a line connects to 2 points.
If a line was infinite length, it would never end up ending at one point.
Hope this was clear for you
