Answer:
210
Step-by-step explanation:

x = 28
#students = 238-x
= 210
The mean of 5 numbers is 11. the numbers are in the ratio 1:2:3:4:5 find the smallest number?
The smallest number is x = 11/3. The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.
Given that the mean of 5 numbers is 11. The numbers are in the ratio 1:2:3:4:5. We need to find the smallest number. We can start solving the problem by following these steps:
Step 1: Let us assume the smallest number to be x.
Step 2: According to the question, the numbers are in the ratio 1:2:3:4:5. Hence, the other four numbers can be written as 2x, 3x, 4x, and 5x.
Step 3: The mean of these 5 numbers is given as 11.
Therefore, we can write:(x + 2x + 3x + 4x + 5x)/5 = 11.
Step 4: Simplifying the above equation, we get:15x/5 = 11x = 11/3.
Step 5: Therefore, the smallest number is x = 11/3.
The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.

Answer:
4 kg : 12 kg : 20 kg
Step-by-step explanation:
The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...
(36 kg)/9 = 4 kg
Multiplying the given ratio by 4 kg will show the appropriate division:
1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg

The total cost c(x) of hiring a dump truck and an operator is described by the function c(x)=300+31x-3.90x^2 , where x is the number of hours worked. Find the number of working hours if c(x)=$220.
Answer:
2.05hrs
Step-by-step explanation:
Given he total cost c(x) of hiring a dump truck and an operator is described by the function c(x)=300+31x-3.90x^2 , where x is the number of hours worked. If c(x)=$220, then;
220 = 300+31x-3.90x^2
300+31x-3.90x^2 - 220 = 0
3.90x^2 + 31x - 80 = 0
x = -31±√31²-4(-80)(3.9)/2(3.9)
x = -31±√961+1.248/7.8
x = -31±47/7.8
x = -31+47/7.8
x = 16/7.8
x = 2.05
hence the number of working hours is 2.05hrs

State the center and radius of the circle based on the equation.
Center = (3,-4) Radius = 5
This equation is already in standard form so you just have to pull out the h and k values which in this case are 3&4, just remember to flip the signs so it'll be 3&-4. Just square the right side and that is the radius, in this case 5
Events AA and BB are independent. P(A\ \mathrm{and}\ B)=0.25P(A and B)=0.25 Enter possible probabilities for events AA and BB.
Answer:0.5, 0.5
Step-by-step explanation:
Given
[tex]P(A\cap B)=0.25[/tex]
Also, A and B are independent events. So, we can write that
[tex]P(A\cap B)=P(A)\times P(B)[/tex]
[tex]0.25=P(A)\times P(B)[/tex]
So, the two most possible value of [tex]P(A)\ \text{and}\ P(B)[/tex] are [tex]0.5\ \text{and}\ 0.5[/tex]
