Answer:
A) reflection over the x-axis and a vertical translation down by 5 units
Step-by-step explanation:
- Making the output negative reflects the graph over the x-axis
- subtracting or adding a constant from/to the function translates it down/up (along the y-axis) by that many units
In this question, we have to convert 12m/s to km/min .
And for the conversion, we need km in the numerator and min in the denominator .
And 1 km equals to 1000 m and 60 seconds equals to 1 minute .
And that's the required conversion factor to convert 12m/s to km/min.
And hence out of the four given options, correct options are A and B .
Answer:
H0: u ≥ 9.5
Ha: u < 9.5
Step-by-step explanation:
The null hypothesis and the alternate hypothesis are reverse of each other.
The claim is either set as the null or alternate hypothesis
The null hypothesis is : H0: u ≥ 9.5 the mean breaking strength of a ceramic insulator is at least 9.5 which is considered equivalent to the standard.
The alternate hypothesis is: Ha: u < 9.5 the mean breaking strength of a ceramic insulator is less than 9.5 which is not considered equivalent to the standard.
Answer:
To calculate the sales tax that is included in a company's receipts, divide the total amount received (for the items that are subject to sales tax) by "1 + the sales tax rate". In other words, if the sales tax rate is 6%, divide the sales taxable receipts by 1.06.
Answer:
321.
Step-by-step explanation:
First, divide 2250 by 7 to see how many times 7 can go in. You should get 321 and 3 as your remainder. To put it into mixed number format, it would put 321 as your whole number and your remainder divided by 7. It would be 321 3/7. Hope this helps :)
