Answer: 49.2 or 49[tex]\frac{1}{5}[/tex]

Step-by-step explanation:

The formula for surface area of a rectangular prism is [tex]2(wl+hl+hw)[/tex]

Where

w is width (5 for this)

l is length ([tex]1\frac{1}{5}[/tex] for this)

h is height (3 for this)

Now lets sub in the values and solve

[tex]2(wl+hl+hw)\\2[(5)(1\frac{1}{5}) +(3)(1\frac{1}{5})+(3)(5)]\\2[6+3.6+15]\\2[9.6+15]\\2[24.6]\\49.2[/tex]

answer: 49.2

step-by-step :

the width is 5

the length is 1  1/5

the height is 3

Answer:

59

Step-by-step explanation:

I answered got it wrong and found the answer

The height 59 inches in most likely closest to the average height of the population.

The correct answer is an option (C)

"It is the ratio of the sum of all given observations to the total number of observations. "

For given question,

We have been given the average heights of four samples taken from a population of students.

The mean(average) of the average height of the population would be,

[tex]\bar{X}=\frac{63+54+57+59}{4}\\\\ \bar{X}=58.25\\\\\bar{X}\approx 59[/tex]

Therefore, the height 59 inches in most likely closest to the average height of the population.

Answer:

Add '-2b' to each side of the equation.

a + 2b + -2b = 12 + -2b

Combine like terms: 2b + -2b = 0

a + 0 = 12 + -2b

a = 12 + -2b

Simplifying

a = 12 + -2b

Answer: b= 6-a/2

Step-by-step explanation:

Always try to isolate what you are looking for.

a+ 2b=12 (subtract a)

2b= 12-a (divide by 2 to isolate b)

b= 12-a/2 (divide both numbers by 2 to get the smallest fraction)

b= 6-a/2 [b is now isolated :) ]

The distance between the boat and the ocean's floor is 19m

We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.

We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).

Then we use the relation:

Sin(a) = (opposite cathetus)/(hypotenuse).

Replacing the values that we know, we get:

Sin(39°) = d/30m

sin(39°)*30m = d = 18.9m ≈ 19m

The distance between the boat and the ocean's floor is 19m.

Answer:

Step-by-step explanation:

Given

We are asked to find F(-1).

This can be done by substituting -1 in place of x in the function.

Step-by-step explanation:

You will have to use the limit defition of the derivative. Brainly does not have calculus symbols, which is very unfortunate, so I can only use my words. Take the limit as the change in 'x' approaches zero. You will have:

[tex] \frac{sin(x + {x}^{.} ) - sin(x)}{ {x}^{.} } [/tex]

If you let "x dot" equal zero as the limit requires, you will get 0/0 which is indeterminate. Break up the first term using the formula for the sine of a sum. You get:

[tex] \frac{sin(x)cos( {x}^{.} ) + sin( {x}^{.})cos(x) - sin(x) }{ {x}^{.} } [/tex]

Factor a sin(x) from the first and third term to get:

[tex] \frac{sin(x)(cos( {x}^{.}) - 1 ) + sin( {x}^{.})cos(x) }{ {x}^{.} } [/tex]

Use the linearity to break the limit into two parts:

[tex] \frac{sin(x)(cos( {x}^{.}) - 1 )}{ {x}^{.} } + \frac{sin( {x}^{.} )cos(x)}{ {x}^{.} } [/tex]

First term converges to zero, second term converges to cosine. Therefore proving the derivative of sine is cosine

The standard deviation of the given data is 3.5

Standard deviation is used to determine the rate of dispersion of data with respect to the mean.

The formula for calculating the standard deviation of data is given as:

[tex]\sigma = \sqrt{\frac{\sum (x-\overline x)^2}{n-1} }[/tex]

Given the data below:

10.4, 10.3, 11.7, 11.1, 8, 4.4, 2.6, 1.8, 2.5, 4.4, 7.3, 9.5

Using the stdevp calculator the standard deviation is calculated as:

σ =  √12.405

σ = 3.5

Hence the standard deviation of the given data is 3.5
