4 is the answer for your question
Answer:
1. 30
2. 370
3. 470
4. 100
Step-by-step explanation:
for one, add the amount of students that play sports and subtract it from 500. for two, add the number of people that only play soccer and only play basketball. for three, take away the 30 people from the 500 kids that don't play. for four, it says 100 people play both.
P=amount of money investedr= interest rate percentage in decimal formt=time in yearsa=total money in the account at a time A = P(1 + rt)A/P = 1 + rtA/P - 1 = rtt = ((A/P)-1)/r t = ((5500/1000)-1)/(6.25/100)t = (5.5-1)/0.0625t = 4.5/0.0625 = 72 years It will take 72 years.
Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
×
= 
Given
×
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
Answer:
D. We are 95% confident that between about 22% and 28% of ESPN Viewers thought the Eagles would still win the division.
Step-by-step explanation:
We have to calculate a 95% confidence interval for the population proportion. The population is made up of ESPN viewers.
The sample proportion is p=0.25.
The standard error of the proportion is:

The critical z-value for a 95% confidence interval is z=1.96.
The margin of error (MOE) can be calculated as:

Then, the lower and upper bounds of the confidence interval are:

The 95% confidence interval for the proportion of ESPN viewers is (0.222, 0.278) or (22.2%, 27.8%).
