<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>

What is the area of the base?

MAXImum [283]

Answer:

24 in²

Step-by-step explanation:

Hello there!

the figure shown is a triangular prism

The base is the triangle

So we need to find the area of the triangle using this formula

$A=\frac{bh}{2}$

where b = base and h = height

The base (triangle) has a base length of 8 inches and a height of 6 inches

Having found the information we needed, we plug it into the formula

So

$A=\frac{6*8}{2} \\6*8=48\\\frac{48}{2} =24\\A=24in^2$

So the area of the base is 24 in²

A sample of size 6 will be drawn from a normal population with mean 61 and standard deviation 14. Use the TI-84 Plus calculator.

AVprozaik [17]

Answer:

$X \sim N(61,14)$

Where $\mu=61$ and $\sigma=14$

Since the distribution for X is normal then the distribution for the sample mean is also normal and given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

$\mu_{\bar X} = 61$

$\sigma_{\bar X}= \frac{14}{\sqrt{6}}= 5.715$

So then is appropiate use the normal distribution to find the probabilities for $\bar X$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean". The letter $\phi(b)$ is used to denote the cumulative area for a b quantile on the normal standard distribution, or in other words: $\phi(b)=P(z$

Solution to the problem

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

$X \sim N(61,14)$

Where $\mu=61$ and $\sigma=14$

Since the distribution for X is normal then the distribution for the sample mean $\bar X$ is also normal and given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

$\mu_{\bar X} = 61$

$\sigma_{\bar X}= \frac{14}{\sqrt{6}}= 5.715$

So then is appropiate use the normal distribution to find the probabilities for $\bar X$

Which construction must you do to construct a triangle given the lengths of two sides and the measure of the angle between the t

Marina86 [1]

The goal is to construct a triangle. If you choose A) you will only have two lines connecting, with an angle of 90°. If you choose B) you cannot have a triangle also with 2 lines only. Neither D). So choose C) construct an angle congruent to a given one-- connect the lines and produce a perfect triangle.

never [62]

Answer:

○ B. $525\:square\:units$

Step-by-step explanation:

All sides meet at right angles, so when split up, you have this:

$525 = 98 + 21 + 154 + 252 = 7 \times 14 + 3 \times 7 + 11 \times 14 + 9 \times 28$

I am joyous to assist you anytime.
