You wrote the equation wrong- he starts with 9 pencils so that's a constant and he sharpens 11 pencils for every minute. The equation would be 9+11x with x being the amount of minutes, which in this case is 7. So you just substitute and solve.

9+11x

9+11(7)

9+77

How many ways can six of the letters of the word 'PALINDROME' be selected and written in a row if the first two letters must be

IgorC [24]

BY permutation, There are 90 ways by which the arrangement of 'PALINDROME' takes place.

According to the statement

we have given that the word 'PALINDROME' and we have to find that the in how much ways this word can be arranged.

So, For this purpose, we use the permutation here

So, A permutation is a mathematical technique that determines the number of possible arrangements.

The word given is:

'PALINDROME' this contain 10 words and given 2 words M and E are in any order.

So, Permutation takes place with $P^{10} _{2}$ .

So,

$P^{10} _{2}$

Now solve this then

$P^{10} _{2} = \frac{10!}{(10 -2) !}$

And

$P^{10} _{2} = \frac{10!}{(8) !}$

$P^{10} _{2} = \frac{10*9*8*7*6*5*4*3*2*1}{(8*7*6*5*4*3*2*1) !}$

And then after take common from them and cancel it the equation become

$P^{10} _{2} = 10*9$

$P^{10} _{2} = 90$

90 ways are comes as the output.

So, BY permutation, There are 90 ways by which the arrangement of 'PALINDROME' takes place.

The time in seconds, t, it takes for a specific object being dropped from a particular height in feet above sea level, h, to rea

Naya [18.7K]

Answer:

B.) 4,096 feet

Step-by-step explanation:

You were given a time, and time in the equation is represented by "t". To find the height, represented by "h", you just need to plug the given value in for "t" and simplify to find "h".

t = (1/4)√x <--- Original equation

16 = (1/4)√x <--- Plug 16 in "t"

64 = √x <--- Divide both sides by (1/4)

4,096 ft = x <--- Square both sides

An article reported that for a sample of 58 kitchens with gas cooking appliances monitored during a one-week period, the sample

Pavel [41]

Answer:

95% Confidence Interval = (611.81 ppm, 696.51 ppm)

Step-by-step explanation:

The formula for Confidence Interval is given as:

Confidence Interval = Mean ± z × s /√n

Mean = the sample mean/average = 654.16

s = the sample standard deviation = 164.55

z = z score of 95% confidence interval = 1.96

Confidence Interval =

654.16 ± 1.96 × 164.55/√58

= 654.16 ± 42.348

Hence,

654.16 - 42.348

= 611.812

Approximately to two decimal places = 611.81 ppm

654.16 + 42.348

= 696.508

Approximately to two decimal places = 696.51 ppm

Therefore, the 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected is (611.81 ppm, 696.51 ppm).
