Step-by-step explanation:
Answer: the employee worked for 41 hours
Step-by-step explanation:
Let x represent the total number of hours that the employee worked. An employee earns $7.00 an hour for the first 35 hours worked in a week and $10.50 for any hour over 35. Let y represent the amount earned for x hours. Therefore
y = 7×35 + 10.5(x - 35)
y = 245 + 10.5x - 367.5
One week's paycheck (before deduction) was for $308.00. This means that y = $308.00. Therefore,
308 =245 + 10.5x - 367.5
308 = 10.5x - 122.5
10.5x = 308 + 122.5 = 430.5
x = 430.5/10.5
x = 41
The p-value of the test is the calculated probability. Hence, the probability must be 18/380. In simplified terms, this is equal to 0.0474 or 4.74%. This is the p-value of the test. The null hypothesis is p < 6%. According to the test, the p-value is 4.74%. Therefore, the null hypothesis is accepted.
The answer is not among the choices. The answer must be 0.0474 or 4.74%.
Answer: 2.5 minutes
Step-by-step explanation: First convert feet to miles. There's 5280 feet in 1 mile, so 3300/5280=0.625 miles. Then find out how long in hours it takes to travel that far. It travels 15 miles an hour, so 0.625/15=0.0417 hours. Then convert hours to minutes by multiplying by 60. 0.0417*60=2.5 minutes.
Answer:
X=8/7
Step-by-step explanation:
7x +2=10
7x=10-2
7x=8. Divide both side by 7
x=8/7
