Answer:
17 days and a half.
Step-by-step explanation:
First, we can find how much money he makes per day cutting lawns. This can be found with the equation:
40 x 5 = 200
He makes $200 a day cutting lawns.
Now we can divide his goal money ($3500) by his daily rate ($200) to get the number of days it will take to reach his goal.
3500 ÷ 200 = 17.5
It will take him 17.5 days to reach his goal.
Answer:
B) 180 ft. squared
Step-by-step explanation:
Multiply all sides of the figure by 3 because of the scale factor
6 times 12 = 72 (for the rectangular part)
6 times 6/2 = 18 (for the triangular part)
We know that the base and height of the triangle are congruent because of the tic marks
18 + 72 = 90
Multiply by 2 since that is only half of the side of the house
90 times 2 = 180
Answer:
D.]
Step-by-step explanation:
We will find the standard deviation and variance:
Variance= E
-[![[E(x)]^{2}](https://tex.z-dn.net/?f=%5BE%28x%29%5D%5E%7B2%7D)
E[x] = 3.462
E[{x}^2]= 31.86
Var(x)= 31.86-(3.462)^2 = 28.4
Standard deviation = 
= 
= 5.833 = 6(aproximately)
Therefore, the chances of winning are equal in each lane.
