<h3><u>Question</u><u>:</u><u>-</u></h3>

If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?

<h3><u>Answer</u><u>:</u><u>-</u></h3><h3 />

22.85714 or 23 days

<h3><u>Explanation</u><u>:</u><u>-</u></h3>

GIVEN,

Number of books Jenny can read in 8 days = 7

NOW,

Number of days taken by Jenny to read 1 book = \frac{8}{7}

Number of days taken by her to read 20 books =

→ 20 \times \frac{8}{7}

→ \frac{160}{7}

→ 22.85714 or 23 days

Answer:

<h2><em><u>23</u></em><em><u> </u></em><em><u>days</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

No. of days taken by Jenny to read 7 books

= 8

<em><u>So</u></em><em><u>,</u></em>

No. of days taken by her to read 1 book

=  \frac{8}{7}

<em><u>Therefore</u></em><em><u>,</u></em>

No. of days taken by her to read 20 books

=  \frac{8}{7} × 20

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  \frac{160}{7}

  • <em>[</em><em>On</em><em> </em><em>dividing</em><em>]</em>

= 22.85.....

  • <em>[</em><em>On</em><em> </em><em>approximating</em><em>]</em>

= 23 days (approx. )

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Jenny</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>take</u></em><em><u> </u></em><em><u>23</u></em><em><u> </u></em><em><u>days</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>read</u></em><em><u> </u></em><em><u>20</u></em><em><u> </u></em><em><u>books</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

It 3x - 2 = 7, then 3x = 9<br> is an example of the ?
vova2212 [387]

Answer:

Addition Property of Equality

Step-by-step explanation:

So we had:

3x-2=7

And then we got:

3x=9

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

(3x-2)+2=(7)+2\\3x=9

Since we added 2 to both sides, this is an example of the addition property of equality.

Find the probability of at least 6 failures in 7 trials of a binomial experiment in which the probability of success in any one
oksano4ka [1.4K]

Answer:

P(x \geq 6)=P(X=6)+P(X=7)

And we can find the individual probabilities:

P(X=6)=(7C6)(0.91)^6 (1-0.91)^{7-6}=0.358

P(X=7)=(7C7)(0.91)^7 (1-0.91)^{7-7}=0.517

And replacing we got:

P(x \geq 6)=P(X=6)+P(X=7)= 0.358+0.517=0.875

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

X \sim Binom(n=7, p=1-0.09=0.91)

The probability associated to a failure would be p =1-0.09 = 0.91

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

And we want to find this probability:

P(x \geq 6)=P(X=6)+P(X=7)

And we can find the individual probabilities:

P(X=6)=(7C6)(0.91)^6 (1-0.91)^{7-6}=0.358

P(X=7)=(7C7)(0.91)^7 (1-0.91)^{7-7}=0.517

And replacing we got:

P(x \geq 6)=P(X=6)+P(X=7)= 0.358+0.517=0.875

\bf y=\cfrac{2x^2-10x}{\sqrt{x}}\implies y=\cfrac{2x^2-10x}{x^{\frac{1}{2}}} \\\\\\ \cfrac{dy}{dx}=\stackrel{\textit{quotient rule}}{\cfrac{(4x-10)(\sqrt{x})~~-~~(2x^2-10x)\left( \frac{1}{2}x^{-\frac{1}{2}} \right)}{\left( x^{\frac{1}{2}} \right)^2}} \\\\\\ \cfrac{dy}{dx}=\cfrac{(4x-10)(\sqrt{x})~~-~~(2x^2-10x)\left( \frac{1}{2\sqrt{x}} \right)}{\left( x^{\frac{1}{2}} \right)^2} \\\\\\ \cfrac{dy}{dx}=\cfrac{(4x-10)(\sqrt{x})~~-~~\left( \frac{2x^2-10x}{2\sqrt{x}} \right)}{x}
