Answer:
Explanation:
The sides of the triangle are :
<span>24cm,28cm</span> and <span>36cm</span>
Explanation:
The ration of lengths are: <span>6:7:9</span>
Let the sides be denoted as:
<span>6x,7x</span> and <span>9x</span>
The perimeter <span>=88cm</span>
<span>6x+7x+9x=88</span>
<span>22x=88</span>
<span>x = </span>
<span>x=4</span>
The sides can be found as follows:
<span>6x=6×4=24cm</span>
<span>7x=7×4=28cm</span>
<span>9x=9×4=36c<span>m</span></span>

Answer:
P(Y = 0) = 0.09
P(Y = 1) = 0.4
P(Y = 2) = 0.32
P(Y = 3) = 0.19
Step-by-step explanation:
Let the events be:
Wednesday
Thursday
Friday
Saturday
Their corresponding probabilities are
Since = number of days beyond Wednesday that it takes for both magazines to arrive(so possible
values are 0, 1, 2 or 3)
The possible number of outcomes are therefore
The values associated for each of the outcomes are as follows:
The probability mass function of is,
For the given geometric sequence, we have:
So the correct option is B.
<h3>Which is the recursive formula?</h3>Here we have the geometric sequence:
To get the initial value of the geometric sequence, we just need to replace n by 1, so we get:
Now, notice that the common ratio is (-1/3), this means that each term of the sequence is (-1/3) times the previous term.
Then the correct option is B.
