So she reads for 5 hours every day for 15 days, how many hours is that? well is just 5*15, or 75 hours.
so, she reads 900 pages in 75 hours, how many pages does she do in 1 hour?
Answer:
(0, 4), (4, 2)
Step-by-step explanation:
Locate each point on the graph. If it is on the blue line, then it is a solution to the equation.
The solutions are:
(0, 4), (4, 2)
Answer:
The correct option is;
e. 2500
Step-by-step explanation:
The formula for sample size is given by the following formula;

At 95%, z = 1.96
ε = Margin of error = 0.02 = 2%
Finding the sample size, n, given only the margin of error is by the following formula;
Margin of error = 100/√n
Therefore, we have;
2 = 100/√n
√n = 100/2 = 50
n = 50² = 2500
Therefore, the correct option is e. 2500.
Answer:
x = negative 1 plus-or-minus StartRoot 17 EndRoot
Step-by-step explanation:
Given:

We need to solve for x.

First we will solve L.H.S
Factorizing the equation we get;

Now Things which are equal to the same thing are also equal to one another. Since


then, according to the law of transitivity,

Now, applying the Square Root Principle we get:

Now Square root and square gets cancelled.

Since a square root has two values, one positive and the other negative.

Hence Final Answer is
.
