We can solve this problem by referring to the standard
probability distribution tables for z.
We are required to find for the number of samples given the
proportion (P = 5% = 0.05) and confidence level of 95%. This would give a value
of z equivalent to:
z = 1.96
Since the problem states that it should be within the true
proportion then p = 0.5
Now we can find for the sample size using the formula:
n = (z^2) p q /E^2
where,
<span> p = 0.5</span>
q = 1 – p = 0.5
E = estimate of 5% = 0.05
Substituting:
n = (1.96^2) 0.5 * 0.5 / 0.05^2
n = 384.16

1/2 of 14 is 7. multiply 14/1 to 1/2.
In a rhombus opposite angles are equal and all 4 add up to 360
assuming one angle is 53, the opposite angle will also be 53 and then adjacent angles will be (360 - (53 x 2))/2 = 254/2 = 127*(deg)

Answer: 65h
Explanation: if the student read 65 pages per house you would multiply the hours read by 65 to determine the number of pages read :)
Answer:
In order of what is shown on the pic:
- Trinomial
- Monomial
- Trinomial
- Binomial
- Polynomial with four terms
Step-by-step explanation:
Again, in the same order as above:
1. The first has three terms, making it a trinomial
2. 7x^2 - 7x^2 +4x
The 7x^2 cancels out and we are left with only 4x
Since there is one value, it is a monomial
3. This one has three terms, making it a trinomial
4. This one has two terms, making it a binomial
5. The last one has four terms, making it a polynomial with four terms.
