Answer:
let x be no. of 4-wheel and y be no. of 3-wheel ATVs
so
x+y=17 (each has one set of handlebars)
4*x + 3*y = 61
4*(x)+3*(17-x)=61
x=61-51=10
y=17-10=7
thus x=10 and y=7 and that's your answer
Answer:
x=71
Step-by-step explanation:
180-38= 142
142/2= 71
it looks like x and the blank space are the same size

Answer:
1/18
Step-by-step explanation:
We are considering that we have 2 dices with 6 faces each (so, the probability to gettig any face in any dish is 1/6). To get an 11, we only have two ways to obtain it:
Dice 1= 6 and Dice 2 =5
or
Dice 1= 5 and Dice 2 =6
So, the probability of the event is given as:
P(Dice1=5 ∧ Dice2=6) ∪ P(Dice1=6 ∧ Dice2=5) = P(Dice1=5) x P(Dice2=6) + P(Dice1=6) x P(Dice2=5) = 1/6 x 1/6 + 1/6 x 1/6 = 1/36 + 1/36 = 2/36 = 1/18.
As 1/18 = 0,055, and 0,055 > 0,05, we consider the event as not significative (according to the definition of significance in the sentence).
The prime factorization of 75 is 3 × 5 × 5 or 3 x 52.
