The answer is 8.8
You have to use SohCahToa to figure out the length of AB
Answer:
19 prizes.
Step-by-step explanation:
First add 153 and 37 which is 190. Then divide 190 and 10. Which is 19.
Answer:
<h2><u><em>
(2s + 5) × (2s + 5)</em></u></h2><h2><u><em>
or</em></u></h2><h2><u><em>
(2s + 5)²</em></u></h2>
Step-by-step explanation:
A side of a square garden is represented by the expression 2s + 5. Which expression represents the area of the garden?
Area = s * s ( side x side or side²)
(2s + 5) * (2s + 5)
or
(2s + 5)²
So the waiting time for a bus has density f(t)=λe−λtf(t)=λe−λt, where λλ is the rate. To understand the rate, you know that f(t)dtf(t)dt is a probability, so λλ has units of 1/[t]1/[t]. Thus if your bus arrives rr times per hour, the rate would be λ=rλ=r. Since the expectation of an exponential distribution is 1/λ1/λ, the higher your rate, the quicker you'll see a bus, which makes sense.
So define <span><span>X=min(<span>B1</span>,<span>B2</span>)</span><span>X=min(<span>B1</span>,<span>B2</span>)</span></span>, where <span><span>B1</span><span>B1</span></span> is exponential with rate <span>33</span> and <span><span>B2</span><span>B2</span></span> has rate <span>44</span>. It's easy to show the minimum of two independent exponentials is another exponential with rate <span><span><span>λ1</span>+<span>λ2</span></span><span><span>λ1</span>+<span>λ2</span></span></span>. So you want:
<span><span>P(X>20 minutes)=P(X>1/3)=1−F(1/3),</span><span>P(X>20 minutes)=P(X>1/3)=1−F(1/3),</span></span>
where <span><span>F(t)=1−<span>e<span>−t(<span>λ1</span>+<span>λ2</span>)</span></span></span><span>F(t)=1−<span>e<span>−t(<span>λ1</span>+<span>λ2</span>)</span></span></span></span>.
