Hope this helps :) have a good day!
How to solve the equation Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
I’m sorry if this is wrong but it’s either
115.992 or 45.0089
Answer:
d. $12.00 and up to $15.00
Step-by-step explanation:
The hourly earnings classes and their respective frequencies are presented bellow:
![\begin{array}{cc}wage&frequency\\\$6\ to\ \$9&16\\\$9\ to\ \$12&42\\\$12\ to\ \$15&10\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7Dwage%26frequency%5C%5C%5C%246%5C%20to%5C%20%5C%249%2616%5C%5C%5C%249%5C%20to%5C%20%5C%2412%2642%5C%5C%5C%2412%5C%20to%5C%20%5C%2415%2610%5C%5C%5Cend%7Barray%7D)
The least occurring class is the $12 to $15 with 10 occurrences.
Therefore, the limits of the class with the smallest frequency is d. $12.00 and up to $15.00
Answer:
Step-by-step explanation:
Distance between two points
and
is given by the formula,
Distance = ![\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2%7D)
a). A(-6, -4), B(-3, -1)
Distance between A and B = ![\sqrt{(-6+3)^2+(-4+1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-6%2B3%29%5E2%2B%28-4%2B1%29%5E2%7D)
= ![\sqrt{9+9}](https://tex.z-dn.net/?f=%5Csqrt%7B9%2B9%7D)
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D = ![\sqrt{(3.5+4)^2+(1-2.5)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%283.5%2B4%29%5E2%2B%281-2.5%29%5E2%7D)
= ![\sqrt{58.5}](https://tex.z-dn.net/?f=%5Csqrt%7B58.5%7D)
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance = ![\sqrt{(5+5)^2+(-5-5)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%285%2B5%29%5E2%2B%28-5-5%29%5E2%7D)
= ![\sqrt{200}](https://tex.z-dn.net/?f=%5Csqrt%7B200%7D)
= 10√2
= 14.14
≈ 14.1 units
