Answer: The fraction that makes up Democrats or Republicans is 49/50.
Step-by-step explanation: There are 100 senators in total. We have 46/100 representing the Democrats, and 13/25 representing the Republicans. The number representing the Republicans can be made into an equivalent fraction of the other simply by multiplying both numerator and denominator by 4 (in order to make the denominator the same, that is 100). Hence the fraction of Republicans is 52/100, while the rest are Independents. The independents are
Ind = 100 - (46/100 + 52/100)
Ind = 100 - 98/100
Ind = 2/100
{Total = 46/100 + 52/100 + 2/100}
{Total = 100/100}
However, the fraction of all senators that are Democrats or Republicans is derived as follows;
Dems = 46/100
Reps = 52/100
Total fraction = 46/100 + 52/100
Total fraction = 98/100
Total fraction = 49/50

Answer:
146%
Step-by-step explanation:
If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.
Your numbers are
old price = $0.92
new price = $2.26
Plug in the numbers in the formula above and evaluate the expression.
percent change = ($2.26 - $0.92)/($0.92) * 100%
percent change = ($1.34)/($0.92) * 100%
percent change = 1.4565 * 100%
percent change = 146%
Since the percent change is a positive number, it is a percent increase.
Answer: The percent increase is 146%.
Answer: Parameter
Step-by-step explanation:
A parameter is defined as :
- A value that is evaluated by considering the entire population.
- For example : Population mean , population standard deviation etc.
A statistic is defined as :
- A value that is evaluated by considering a sample of the population.
- For example : sample mean , sample standard deviation etc.
Given : Mark had competed in the 100-meters event a total of 328 times.
Here , Population of interest = Number of times Mark competed in the 100-meters event =328
His average time for these 328 races was <u>15</u> seconds.
Since this average is calculated from the entire population, therefore , 15 is representing a parameter .
Hence, the correct answer is : "Parameter"
