F(1) means you’re replacing the X with 1, therefore all you’re doing it 3(1)+1. Which will get you 4

Al and Bill each have two bullets. They fire alternately at a glass bottle. Al has hitting probability 1/3 and Bill 1/4. What is

enot [183]

P(Al hits bottle first time) = 1/3
P(Al misses the first shot but hits on his second shot) =
P( Al misses and bill misses and Al hits) = 2/3 * 3/4 * 1/3 = 1/6

So required probability = 1/3 + 1/6 = 1/2

Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .

SOVA2 [1]

The general rule for the nth term of the sequence is $a(n)=-6b+(n-1)(3b)$

Explanation:

The sequence is -6b, -3b, 0b, 3b, 6b, .....

To find the nth term of the sequence, we need to find the common difference and the first term of the sequence.

First term of the sequence = -6b

Common difference = $-3b-(-6b)=-3b+6b=3b$

Using this the nth term of the sequence can be determined.

Since, this is an arithmetic sequence, the general form of AP is given by the formula,

$a(n)=a+(n-1)d$

where a denotes the first term of the sequence and d denotes the common difference. Thus, $a=-6b$ and $d=3b$

Substituting the values in the general formula, we get,

$a(n)=-6b+(n-1)(3b)$

Thus, the general rule for the nth term of the sequence is $a(n)=-6b+(n-1)(3b)$

A little Challenge.

zubka84 [21]

Step-by-step explanation:

the total area of circles =

(2 × π × 1²) + (3 × π × 0.5²)

= (2π) + ( 3× 0.25×π)

= 2π + 0.75π

= 2.75π

assume π=3.14

so, the total area =

2.75 × 3.14 = 8.635
