Y=-5/12x-11/12
the slope is -5/12 the y intercept is -11/12
Since you're looking at 2 standard deviations from the mean, you follow the 66 95 rule which says 95 % of the data is within 2 standard deviations. however you just need half of that since the other half is on the other side of the data meaning it last longer than 7 days. So 2.5% is the answer.
Answer:
180mm^2
Step-by-step explanation:
CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm
CB is 16mm
the area of the triangle is A=ab/2
A=45mm^2
Now you need to find the area of the rectangle
A=l×w
A= 15×9= 135mm^2
now add both areas
(135+45)mm^2=180mm^2
Calculating Total Cost. 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. Multiply retail price by tax rate
Let's say you're buying a $100 item with a sales tax of 5%. Your math would be simply: [cost of the item] x [percentage as a decimal] = [sales tax]. That's $100 x .
Let the number be xy ,
xy = 10x + y. when reversed = yx = 10y + x
x = 2y ........(a)
10x + y + 10y + x = 66.........(b)
10(2y) + y + 10y + 2y = 66
20y + y + 10y + 2y = 66
33y = 66
y = 66/33
y = 2
x = 2y = 2*2 = 4
Recall the original number is xy = 42.
