Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
Answer:
Reflection over the line y=-1
Step-by-step explanation:
Answer: When a = 8, one of the roots of the equation will be 1.
To solve this problem, you could graph the equation with a 1 in the place of the a on a graphing calculator (there are some online).
Then, just keep changing the a value until the graph crosses the x-axis at 1. When, you enter an a value of 8, it will have a root of 1.
♡Let's solve this Step-By-Step!<span>♡
</span>♡<span>Question:
A=2(L+w)
♡</span>To solve for W we need to flip the equation like so:
<span><span>2l</span>+<span>2w</span></span>=<span>a
</span>
♡Now a<span>dd -2l to both sides:
</span><span><span><span>2l</span>+<span>2w</span></span>+<span>−2l</span></span>=<span>a+<span>−<span>2l
</span></span></span><span>2w</span>=<span>a−<span>2<span>l
</span></span></span>
♡<span>Divide both sides by 2:
</span><span><span>2w/</span>2</span>=<span><span>a−<span>2l/</span></span><span>2
</span></span>♡<span>Your answer shall be:
</span>w=<span><span><span>1/2</span>a</span>−l
</span>
♡Hope this helps!♡
