Consider the arithmetic sequence 13, 24, 35, ....

Nostrana [21]

Answer: 27

Step-by-step explanation:

The given sequence : 13, 24, 35, ....

Here, first term : a= 13

Common difference: d=24-13 =11

The nth term of arithmetic sequence is given by :-

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

It is given that the nth term is 299, so put $a_n=299, a=13 ; d=11$

$299=13+(n-1)11$

Subtract 13 from both sides , we get

$286=(n-1)11$

Divide both sides by 11, we get

$26=n-1$

Add 1 on both sides , we get

$n=27$

Hence, the value of n= 27

Patty made a banner that has an area of 175 square inches. The length and width of the banner are whole numbers. The length is 7

Leviafan [203]

Answer:

Length = 35

w = 5

Step-by-step explanation:

l x w = area

7y x y = 175

7y^2 = 175

y^2 = 175/7

y^2=25

y=5

The length is 7y, so it's 5 times 7 or 35.

The width is just y, so it's 5.

A wireless service provider charges $30 + 0.10m, where m represents the number of text messages sent. How much would you pay if

DochEvi [55]

→Amount charged by wireless service provider when 'm' messages are sent=$(30+0.10 m)

Amount charged if ' 1 ' messages are sent= $30+0.10×1=$30.10

Amount charged when '2' messages are sent=$30+0.10×2=%30.20

.....................................................

Amount charged or money you will pay when 'u' messages are sent=$30+0.10×u=$(30+0.10 u)

If records indicate that 15 houses out of 1000 are expected to be damaged by fire in any year, what is the probability that a wo

nordsb [41]

Answer: 0.01708

Step-by-step explanation:

Given : If records indicate that 15 houses out of 1000 are expected to be damaged by fire in any year.

i.e. the probability that house damaged buy fire in a year : $p=\dfrac{15}{1000}=0.015$

The formula for binomial distribution is given by :-

$^{n}C_xp^x(1-p)^{n-x}$

Now, the probability that a woman who owns 14 houses will have fire damage in 2 of them in a year (put n=14 and x=2), we get

$^{14}C_2(0.015)^2(1-0.015)^{14-2}\\\\=\dfrac{14!}{2!(14-2)!}(0.015)^2(0.985)^{12}\\\\=0.0170788520518\approx0.01708$

Hence, the required probability = 0.01708
