Answer:
14/21
Step-by-step explanation:
1. Find the value of x
Step 1: Write it as an equation.
Step 2: Cross-multiply.
Step 3: Divide both sides by 3.
2. Now that we know the numerator is 14 and the denominator is 21, we can write it as a fraction: 14/21.
The formula is
I=prt
I interest?
P 220
R 15400/100=154
T time 1 year
I=220×154×1
I=33,880
It's d
Well if you notice, 48, x, and x are all on the same line, so they must add up to equal 180 degrees. So...
2x + 48 = 180
2x = 132
x = 66
So each x is equal to 66 degrees. Now we know the triangle is a right triangle, and the sum of all interior angles must be equal to 180 degrees for a triangle. So...
66 + 90 + z = 180
156 + z = 180
z = 24
Z equals 24 degrees! I hope this helps!
Answer:
p = 0.52392
Step-by-step explanation:
Here we have
p = 23% = 0.23
= 208/800 = 0.26
n = 800
q = 1-p = 0.77
α = 5% = 0.05
Here we have
Z test given by
From which we have
From the Cpdf we have Probability = 0.0219, z = 2.016
Therefore from the z score = 0.0683, p = 0.52392 from z table.
