Answer:
86.6% ; 93.4%
Step-by-step explanation:
To obtain the population proportion from the sample, we calculate the confidence interval ;
Confidence interval = phat ± margin of error
Phat = 90% ; margin of error = +3.4%
Hence,
90% ± 3.4%
(90 - 3.4)% ; (90 + 3.4)%
86.6% ; 93.4%
Silver = 10%
Gold = 90%
Amount of gold to be deducted
90/100 × 18 = 16.2 g
75/100 × 18 = 13.5
16.2 - 13.5 = 2.7
Amount o silver to added.
2.7 × 5 = 13.5
Answer = 13.5 g
Answer:
v = 196.25
Step-by-step explanation:
v = 3.14*r^2*h
v = 3.14*5^2*2.5
v = 196.25
Let's make our equation in the form of y = mx + b
<span> 2x – 6y = 9
Add 6y on both sides
2x = 6y + 9
Subtract 9 on both sides
6y = 2x - 9
Divide 6 on both sides
y = 1/3 - 3/2
Now, we have it in the form of y = mx + b
In y = mx + b, m is the slope and b is the y-intercept
That means in y = 1/3 - 3/2, the slope is A) 1/3.
Your answer is A) 1/3</span>
Answer:
So there are alot of various properties that could be used to solve different kinds of algebraic expressions. To solve a simple algebraic equation, most of the times u need to know the, addition, subtractions properties as well as division and multiplication division property.
Hope this helps!
