Consider an event to be unlikely if its probability is less than or equal to 0.05.
204+287+376+137+130=1134
130/1134= .115
No, because the probability of a respondent with four or more cell phones in use is greater than 0.05.
I think it’s 25.12 or C
to find circumference u multiply diameter by 3.14.
to find radius you multiply diameter by 2
diameter is 4. multiply diameter by 2 and u get 8
8 x 3.14= 25.12
Answer:
y = 6x - 40
Step-by-step explanation:
I'll be honest, this is a pretty interesting question. I've never seen anything like it before!
We can start off by making equations with the given. If there are 100 heads, that means that the total number of chickens and pigs combined is 100. Thus, we can form our first equation:
p + c = 100
('p' represents number of pigs, and 'c' represents number of chickens)
We also know that there are 270 legs total. Since chickens have 2 and pigs have 4, we can make the following equation:
2c + 4p = 270
I suppose the quickest way to solve for this equation is to use the subtraction method. Put the equations on top of each other:
2c + 4p = 270
c + p = 100
___________
Multiply the bottom equation by -2;
2c + 4p = 270
-2c -2p = 100
____________
"Add" these two equations together:
2c + 4p = 270
-2c -2p = -200
___________
2p = 70
Divide both sides by 2:
p = 35
Ah, finally. Now that we know that there are 35 pigs, input this variable into the first equation to find the number of chickens:
c + 35 = 100
Subtract:
c = 65
There are 35 pigs and 65 chickens
-T.B.
$=pn right? Because it's the price per mile, times the number of miles traveled.
