D
Step-by-step explanation:
A polynomial of degree 2 has 2 roots, either real or complex
5.75% of 25 is 1.43
20% of 25 is 5
25+5=30+1.43=$31.43

The area (A) of a square is determined by using the formula, A = s² where s is the measure of each side. Given s = 3 ft, the area of the square is
A = (3 ft)² = 9 ft²
Doubling the sides makes them 6 ft. The new area is, A = (6 ft)² = 36 ft². The new area is not double of the previous area but four times. The new area (An)
An = (2s) ² = 4s² = 4A
Answer:
<em>The unit rate for the price to the length of the fabric will be $8 per meter.</em>
Step-by-step explanation:
The two points on the graph of the line are: (1, 8) and (3, 24)
For finding the unit rate for the price to the length of the fabric, we just need to find the slope of that line.
Formula for finding the slope is: , where and are two given points.
Here, and
So, the slope of the line will be:
Thus, the unit rate for the price to the length of the fabric will be $8 per meter.
Answer:
A: The 10 percent condition states that the population is greater than 10 times the sample, or 10n. In other words, the sample size must be no more than 10 percent of the population. In this problem, the sample size is 7, and the population is 38. This means that 38>10n, or 38>10 times 7, or 70. 38 is not greater than 70, therefor the 10 percent condition is not met in this case.
B: In this problem, p, or the population proportion is 14/38. The conditions of normality are that n times p and n times 1-p are both greater than 5. n=38 and p, as stated, equals 14/38. This means that n times p equals 14, and n times 1 minus p equals 24, which are both greater than 5. This means that both of the normality condition have been met.
