The five posters made for spirit week are being hung in the front hall. What is the probability the largest poster will be in th

Leto [7]

Answer:

1/20 or 0.05

Step-by-step explanation:

Assuming that all five posters are different, the number of ways to randomly place those posters is given by:

$N=5*4*3*2*1 = 120\ ways$

If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:

$n=3*2*1*1*1=6\ ways$

Therefore, the probability is:

$P=\frac{n}{N}=\frac{6}{120} =\frac{1}{20} =0.05$

The probability is 1/20 or 0.05.

Find the sum of the first 30 terms of the sequence below an=3n+2

Solnce55 [7]

First off, let's find the 1st term's value, and the 30th term's value,

$\bf a1=3(1)+2\implies a1=5\qquad \qquad \quad a30=3(30)+2\implies a30=92\\\\
-------------------------------\\\\
~~~~~~~\textit{ Sum of an arithmetic sequence}\\\\
S_n=\cfrac{n(a1+an)}{2}~ 
\begin{cases}
n=n^{th}\ term\\
a1=\textit{first term's value}\\
----------\\
a1=5\\
a30=92\\
n=30
\end{cases} \implies S_{30}=\cfrac{30(5+92)}{2}
\\\\\\
S_{30}=15(97)$

What is g. 59 + 2p + 4 = 39 -8,

Lera25 [3.4K]

Hello there. Since g isn't on here, I'll solve for p.

First, solve anything that you can. 59+4 is 63. Subtract 63 from both sides.

2p=-32

p=-16

Therefore, the answer is p=-16.

While Diane was visiting her sister in Kingwood, she bought a bunch of balloons that was marked down 20% from an original price

shepuryov [24]

Answer:

$4.34

Step-by-step explanation:

Given the information:

The original price: $5
Discount : 20%
Tax: 8.5%

We can find out the actual price that Diane bought a bunch of balloons that was marked down 20% is:

= the original price (100% - discount rate)

= 5(100% -20%)

= $4

The tax amount she need to pay is:

= The actual price*tax rate

= $4*8.5%

= $0.34

=> the total cost of the bunch of balloons :

The actual price + tax price

= $4 + $0.34

= $4.34

Hope it will find you well.
