prisoha [69]
First, lets convert our dimensions into cm. 

2*2.54 = 5.08 cm.
1.5*2.54 = 3.81 cm.

Now, lets multiply by for the get the dimensions of the original painting in inches. 

5.08*40 = 203.2 cm
3.81*40 = 152.4 cm

Finally, lets divide our new dimensions.

203.2/2.54 = 80 in.
152.4/2.54 =  60 in.

The dimensions of the original painting is 80 in. by 60 in.

Pls help me this is for my final text and I’m struggling really bad!!!
vodka [1.7K]
I’m not so sure I fully understand the question. But I would say the rate is 1.

I say this because the line on your graph is a y=mx+b equation.

For every unit it moves over on the X axis it moves the same unit on the Y axis.

I hope this helps.

Ede4ka [16]

Answer:

The sampling distribution of X, for a sample of size 16, will be approximately normal with mean 2 mm and standard deviation 0.01 mm.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For the population:

Mean 2 mm, standard deviation 0.04 mm

Describe the sampling distribution of X (for a sample of size 16).

Sample of size 16 means that n = 16

By the Central Limit Theorem, approximately normal with mean 2 and standard deviation s = \frac{0.04}{\sqrt{16}} = 0.01

This monitor has a diagonal length of 19 inches and an aspect ratio of 5:4. What are the width and height of the monitor? Round
nasty-shy [4]

<em>Rounded to the nearest tenth of an inch the Witdth of the monitor is 14.8 inches while the Height of the monitor is 11.9 inches.</em>

<h2>Explanation:</h2><h2 />

The aspect ratio is defined as:

<em>"The proportional relationship between the width and height of an image"</em>

It is usually expressed in a mathematical language as:

x:y \\ \\ x: \ Width \\ \\ y: \ Height

So, it is true that:

x:y=5:4 \\ \\ or: \\ \\ \frac{x}{y}=\frac{5}{4} \\ \\ \therefore x=\frac{5y}{4}

In this case, we know that the monitor has a diagonal length (D):

D=19in

So, by Pythagorean theorem:

D^2=361 \\ \\ 361=x^2+y^2 \\ \\ Since \ x=\frac{5y}{4}

D^2=361 \\ \\ 361=x^2+y^2 \\ \\ Since \ x=\frac{5y}{4} \\ \\ 361=\left(\frac{5y}{4}\right)^2+y^2 \\ \\ 361=\frac{25y^2}{16}+y^2 \\ \\ \frac{41}{16}y^2=361 \\ \\ y^2=\frac{261\times 16}{41} \\ \\ y=\sqrt{140.87} \\ \\ y=11.869in

Finding x:

x=\frac{5(11.869)}{4} \\ \\ x=14.836in

<em>Finally, rounded to the nearest tenth of an inch the Witdth of the monitor is 14.8 inches while the Height of the monitor is 11.9 inches.</em>
