Answer:

12.5% chance

Step-by-step explanation:

There 24 students in total

When you divide the fraction out, you get 0.125. To turn that into a percentage, you simply multiply by 100. 0.125*100=12.5% you can check this by taking 12.5% of 24, which will give you an answer of 3.

Write the first five terms of the sequence defined by the recursive formula

stepan [7]

Answer:

The correct answer option is: $S_9=\frac{9}{2} (2+26)$

Step-by-step explanation:

We know that,

the sum of the first $n$ terms of an Arithmetic Sequence is given by:

$S_9=\frac{n(a_1+a_n)}{2}$

where $n$ is the number of terms,

$a_1$ is the first term of the sequence; and

$a_n$ is the first term of the sequence.

So for $a_n=3n-1$ ,

$a_1=3(1)-1=2$

and

$a_9=3(9)-1=26$

Putting these values in the formula to get:

$S_9=\frac{9(a_1+a_9)}{2}$

$S_9=\frac{9(2+26)}{2} \\\\S_9=\frac{9}{2} (2+26)$

First five terms:

$a_1=3(1)-1=2$

$S_1=\frac{1(2+2)}{2}$ =2

$a_2=3(2)-1=5$

$S_2=\frac{2(2+5)}{2}$ =7

$a_3=3(3)-1=8$

$S_2=\frac{3(2+8)}{2}$ =15

$a_4=3(4)-1=11$

$S_4=\frac{4(2+11)}{2}$ =26

$a_5=3(5)-1=14$

$S_5=\frac{5(2+14)}{2}$ =40

Answer:

Step-by-step explanation:

3/4 cups → 1 batch

x cups → 2 batches

x = 2(3/4) = 6/4 = 1 1/2 cups

3/4 cups → 1 batch

y cups → 9 batches

y = 9(3/4) = 6 3/4 cups
