A, You can construct the frequency table with the conditions follow:
1. x∈(0;100]
2. x∈(100;200]
3. x∈(200;300] (there are a famillies)
4. x∈(300;400] (there are b famillies)
5. x∈(400;500]
b, You must know the number of famillies whose monthly utilities bills are x∈(200;400], that the sum of famillies of table 3 and table 4.
So the result is: [(a+b)/35]*100%

Answer:
f(x)=0.333*(1*x+-4)*(1*x+1)
Step-by-step explanation:
<u>Your exercise:</u>
Find a quadratic function with roots at 4 and -1 whose graph goes through the point -2 .
The function f(x)=a*(1*x+-4)*(1*x+1) has the desired roots.
Insert the point (1, -2) to find a.
-2=a*(1*1+-4)*(1*1+1)
-2=1*a*(1*1+-4)*(1*1+1) (add 1 to -4)
-2=1*a*-3*(1*1+1) (add 1 to 1)
-2=1*a*-3*2 (Multiply -3 by 2)
-2=1*-6*a (Swap both sides of the equation.)
-6*a=-2 : (-6)
1*a=0.333
f(x)=0.333*(1*x+-4)*(1*x+1)
Answer:
No. Vivian will not make it to her friends house.
Step-by-step explanation:
If Vivian will be riding 15 miles per hour, and she has six hours , then in order to find out the distance, we will have to multiply the rate and the time.
Equation : 15x6 = 90
Using this solution, we can easily find out that 90 is less than 96 as shown.
90<96
In conclusion, no Vivian will not make it to her friends house within the 6 hours she has to get there.
Hope this helps!
