Answer:
X=67.5
Step-by-step explanation:
3X + X=4X
4X+90=360
4X=360-90
4X=270
X=67.5
Answer:
Step-by-step explanation:
Your equation is: 
You also know that x = -3 and y = 2. You can rewrite the equation by substituting x and y with their actual values:
First, you want to do the exponentiation (meaning you want to calculate
and
parts).
equals 9 and
equals 16.
So the equation now is:

Now you want to do multiplication.
equals 36 and
equals 32. So you're left with:

Which equals 68.
Answer: 0.24 +/- 0.088 = (0.152, 0.328)
Step-by-step explanation:
The point estimate p is given by;
p= 24/ 100 = 0.24
Z value for 96% confidence interval is 2.05
The solution for the given confidence interval is derived using the equation
p +/- z√(pq/n)
Where p = 0.24 q= 1-p = 0.76, n=100 z= 2.05
= 0.24 +/- 2.05√(0.24×0.76/100)
= 0.24 +/- 2.05(0.0427)
=0.24 +/- 0.088
= ( 0.152, 0.328)
