Solution
Number of weeks in a year = 52 weeks
If in a normal year when each package of flea treatment lasts for 4 weeks, then in a year there Jim's dog will have to be treated for

Where as, when the fleas are bad in a year, the treatment lasts for only 3 weeks.
Then in a year Jim's dog would get

So Jim's dog will get 17- 13 =4 treatments more.
4 treatments that are made in 3 weeks each will be 4×3 =12 weeks more treatment
Answer:
Provided in the picture below.
Step-by-step explanation:
Provided in the picture below.
13 + 6 + 3 + 7 + 11 = 40
;
40 ÷ 5 = 8
;
13 - 8 = 5
6 - 8 = |-2| = 2
3 - 8 = |-5| = 5
7 - 8 = |-1| = 1
11 - 8 = 3
;
5, 2, 5, 1, 3
5 + 2 + 5 + 1 + 3 = 16
16 ÷ 5 = 3.2
;
Mean Absolute Deviation is 3.2.
Hope this helped☺☺
Step 1: convert the equation into fhe vertex form
To do you can complete squares:
y = - [x^2 + 4x + 3]
y = - [ (x + 2)^2 - 4 + 3]
y = - [ (x + 2)^2 - 1] = - (x+2)^2 + 1
Then the vertex is (-2, 1)
Now you can drasw the vertex
Step 2: Find the roots (zeros)
y = - [ (x + 2)^2 - 1] = 0
(x + 2)^2 - 1 = 0
(x+2)^2 = 1
(x+2) = (+/-) √1
x + 2 = (+/-1)
x = - 2 +/- 1
x = -1 and x = -3
Now you draw the points (-1,0) , (-3,0)
Step 3: find the interception with the y-axis.
That is y value when x = 0
y = - (0)^2 - 4(0) - 3 = -3
Then draw the point (0, -3)
Step 4: given that the coefficent of x is negative (-1) the parabola is open downward.
So, with those four points: vertex (-2,1), (-1,0), (-3,0) and (0,-3), you can sketch the function.
Answer:
The following are the correct statements regarding mathematics in the Egyptian, Chinese, and Babylonian cultures:
Both Egyptian and Chinese number systems use base 10.
All three cultures had unique symbolism to represent their numbers . (Earlier symbols were used to depict things)
There are two primary sources for ancient Egyptian mathematics
(The primary sources are the Rhind Papyrus and the Moscow Papyrus)
