Answer:
<h2>37/9</h2>
Step-by-step explanation:
<h3>we have</h3>
<h3>3.77777... :- is a repeating decimal</h3>
<h3>Let</h3>
<h3>x = 3.7...</h3>
<h3>so</h3>
<h3>10x =37.7...</h3>
<h3>10x - x = 37.7... -3.7...</h3>
<h3>9x=34</h3>
<h3>x= 34/9</h3>
<h3>convert to mixed number</h3>
<h3>34/9=(27/9)+(7/9)=3+(7/9) =37/9</h3>
<h3> I hope this may help you.</h3>
Answer:
6
Step-by-step explanation:
2 halves make a whole so multiply 2 by 3. the answer is six. you can also add the halves. 1/2+1/2+1/2+1/2+1/2+1/2=3.
Answer:
0.1319 or 13.2%
Step-by-step explanation:
You can solve this using the binomial probability formula.
The fact that "obtaining at least two 6s" requires you to include cases where you would get three and four 6s as well.
Then, we can set the equation as follows:
P(X≥x) = ∑(k=x to n) C(n k) p^k q^(n-k)
n=4, x=2, k=2
when x=2 (4 2)(1/6)^2(5/6)^4-2 = 0.1157
when x=3 (4 3)(1/6)^3(5/6)^4-3 = 0.0154
when x=4 (4 4)(1/6)^4(5/6)^4-4 = 0.0008
Add them up, and you should get 0.1319 or 13.2% (rounded to the nearest tenth)
We know that
<span>1 1/8 gallons----------> (1*8+1)/8-------> 9/8 gallons
</span><span>13 1/2 miles----------> (13*2+1)/2-------> 27/2 miles
if 9/8 gallons-------------------> 27/2 miles
1 gallons----------------------> X
X=(27/2)/(9/8)---------> 216/18--------> 12 miles
the answer is 12 miles</span>
