Suppose heights of seasonal pine saplings have an unknown distribution with mean 291 and standard deviation 14 millimeters. A sample of size n=55 is randomly taken from the population and the mean is taken. Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?

Answers

Answer 1

Answer:

1.89

Step-by-step explanation:

The center al limit theorem for means states that the standard deviation of the normal distribution of sample means is equal to the original distribution’s standard deviation divided by the square root of the sample size. the original standard deviation is 14 and the sample size is 55.

Answer:

I think the answer is 1.78

Step-by-step explanation:

The diameter of the sphere will be equal to 4.59 feet.

What is a sphere?

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

Given that:-

The spheres cost $2 per square foot and Selim can spend $20 per sphere. What is the maximum diameter of the spheres he can purchase?

The area of the sphere will be = 20 / 2 = 10 square feet

The diameter of the sphere will be calculated as:-

Area = 4 π r  

10  =  4 π r

r  =  10 / (  4 π )

r  =   0.79 feet

D = 2r = 2 x 0.79 = 1.59 feet

Therefore the diameter of the sphere will be equal to 4.59 feet.

A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
O 2y = 16x +14
O y = 8x - 7
O y = -8x + 7
O 2y = -16x - 14

Answers

Answer: y=8x-7 just took the quiz hope that helps

The other equation could be y = 8x - 7

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

to determine the other equation:

The first equation is given as:

y = 8x + 7

For the system of equation to have no solution, then the equations in the system would have different constant values.

Take for instance:

y = 8x + b

Where:

b is a constant not equal to 7

From the options, we have:

y = 8x - 7

Notice that -7 and 7 are not the same

Hence, the other equation could be y = 8x - 7

Given the following data:

A normalized exponential form.

In Computer technology, binary numbers like decimal numbers in mathematics can be written in an exponential form and it involves the use of powers of two (2) rather than powers of ten (10).

Additionally, all non-zero binary numbers have a unique normalized exponential form and their binary point must always appear before the first one (1) bit, which yields a unique integer (exponent) and a unique mantissa respectively.

Thus, the normalized exponential form for the given binary number is written as follows:

[tex]1011.101_2 = 0.1011101 \times 2 ^4[/tex]

If H1(x) is the inverse of H(x) , what is the value of H1 (H(x)) ?

Answers

In a function, you feed in x and get y.
In the inverse function, if you feed in y, you get x

So basically if you take the inverse of the original function, you get back the original input.

Hence:
H^-1(H(x)) = x

Take this example:
H(x) = 3x
H^-1(x) = x/3

H^-1(H(7))
--> H(7) = 3(7) = 21
--> H^-1(21) = 21/3 = 7

Answer:

  34.5 square meters

Step-by-step explanation:

We assume you want to find the area of the shaded region. (The actual question is not visible here.)

The area of the triangle (including the rectangle) is given by the formula ...

  A = 1/2bh

The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...

  A = (1/2)(11 m)(9 m) = 49.5 m^2

The rectangle area is the product of its length and width:

  A = LW

The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...

  A = (5 m)(3 m) = 15 m^2

The shaded area is the difference between the triangle area and the rectangle area:

  shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2

The shaded region has an area of 34.5 square meters.

Jack's family took a road trip to Mount Rushmore. Jack slept through the last 65% of the trip. If the total length of the trip was 700 miles, how many miles had they travelled when Jack fell asleep?

Answers

Using proportions, it is found that they had traveled 245 miles when Jack fell asleep.

What is a proportion?

A proportion is a fraction of a total amount.

Jack slept through the last 65% of the trip, hence he fell asleep when 100 - 65 = 35% of the 700 mile trip had been traveled, so:

0.35 x 700 = 245.

I'm not sure what it means by "define the types of linear" (maybe theres a given function?), but to find the x intercept you need to make y 0. For example:

if we have a function

f(x) = 2x + 1

and we want to find the x intercept we substitute 0 to y

0 = 2x + 1

not

f(0) = ......

Answer:

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. How do you find the Y intercept in a word problem? When a word problem involves a constant rate or speed and a beginning amount, it can be written in slope-intercept form: y=mx+b.
