The first platform of the Eiffel Tower is 2,280 inches above the ground. The second platform is 376 feet above the ground. How many yards separate the first platform from the second platform?
Answer:
62.0496 yards separate the first platform from the second platform
Step-by-step explanation:
We have to make the conversion of both units to yards.
Each feet has 12 inches.
Each inch is 0.0278 yards.
The first platform of the Eiffel Tower is 2,280 inches above the ground.
So
2280*0.0278 = 63.384 yards above the ground.
The second platform is 376 feet above the ground.
So
376*12*0.0278 = 125.4336 yards above the ground
How many yards separate the first platform from the second platform?
125.4336 - 63.384 = 62.0496
62.0496 yards separate the first platform from the second platform
given a population mean of 27.1 with a standard deviation of 8.4 and a sample size of 10, answer these questions.
part A: what is the standard deviation of the sampling distribution of x hat? show your work.
PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8? show your work.
Answer:
a) 2.66
b) 9
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
part A: what is the standard deviation of the sampling distribution of x hat? show your work.
We have that [tex]\sigma = 8.4, n = 10[/tex]. So
[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{8.4}{\sqrt{10}} = 2.66[/tex]
PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8?
This is n when [tex]s = 2.8[/tex]. So
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]2.8 = \frac{8.4}{\sqrt{n}}[/tex]
[tex]2.8\sqrt{n} = 8.4[/tex]
[tex]\sqrt{n} = \frac{8.4}{2.8}[/tex]
[tex]\sqrt{n} = 3[/tex]
[tex](\sqrt{n})^2 = 3^2[/tex]
[tex]n = 9[/tex]

(25m + 22) + (9m) = ?
Answer:
Step-by-step explanation:
Simplifying
25m + 22 = 9m
Reorder the terms:
22 + 25m = 9m
Solving
22 + 25m = 9m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-9m' to each side of the equation.
22 + 25m + -9m = 9m + -9m
Combine like terms: 25m + -9m = 16m
22 + 16m = 9m + -9m
Combine like terms: 9m + -9m = 0
22 + 16m = 0
Add '-22' to each side of the equation.
22 + -22 + 16m = 0 + -22
Combine like terms: 22 + -22 = 0
0 + 16m = 0 + -22
16m = 0 + -22
Combine like terms: 0 + -22 = -22
16m = -22
Divide each side by '16'.
m = -1.375
Simplifying
m = -1.375

Find two consecutive numbers whose sum is 55
Answer:
27 and 28
Step-by-step explanation:
Answer and Step-by-step explanation:
27 and 28.
27 plus 28 equals 55.
To know which numbers to use, we have to find two numbers that would produce a number that would include the digit of the second number in 55. Then, we find numbers that add up to 5, then minus by 1.

On a cruise ship there are two options for an Internet connection. The first option is a fee of $5 plus an additional $0.25 per minute. The second option cost $50 for an unlimited number of minutes. For how many minutes, m, is the first option cheaper than the second option? BRAINLIEST!!!
Answer:
m=180
Step-by-step explanation:
5+0.25m=50
-5. -5
0.25m=45
divide both terms by 0.25
m=180
with the first option you can get 180minuts or 3hours for the equivalent of the $50 option.

In the case above about Samuel, we can say that Samuel's calculator has display option A; 2.5 E (- 13)
What is the calculation about?The function was 5 EE (-) 9 divided by 2 EE 4
5 EE (-) 9/ 2 EE 4
We know that, E implies 10 to rise to power.
So, the equation above is Converted from scientific notation into standard form;
= 5 EE (-) 9/ 2 EE 4
= 5/2 x 10 ⁻⁹⁻⁴
=2.5 x 10⁻¹³
Therefore, In the case above about Samuel, we can say that Samuel's calculator has display option A; 2.5 E (- 13)

30 kilograms of beans costs $5. How many kilograms of beans can you buy for $20?
Answer:
120 kg
the kilograms of beans which can by for $20 are
30*(20/5) = 30.4 = 120 (kg)
Answer: 120 kilograms
Step-by-step explanation:
We can buy 30 kilograms of beans for $5 dollars. We need to find how many kilograms of beans we can buy for $20.
The first step is to divide 20 by 5. Then, using the quotient, we can multiply it by 30 to see how many kilograms of beans we can buy for $20.
20 ÷ 5 = 4.
4 x 30 = 120.
Therefore, we can buy 120 kilograms of beans for $20.

Which of the following is the equation of a line perpendicular to the line y =
-10x+1, passing through the point (5,7)?
Answer: The answer is C.
Step-by-step explanation: This is because when you solve you get y=1/10x+6.5 this graph runs through the point (5,7) and is perpendicular to y=-10x+1. In order for two equations to be perpendicular their slopes will be the opposite.

Given that L is a linear function, L (5) = 100 and L (9) = 150.
a. Determine the value of L (13)
Answer:
L(13) = 200
Step-by-step explanation:
Linear function:
A linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).
Finding the slope:
L (5) = 100 and L (9) = 150.
The slope is given by the change in the output(L, which is equals to y in the general formula) divided by the change in the input(x).
Change in the output: 150 - 100 = 50
Change in the input: 9 - 5 = 4
Slope: [tex]m = \frac{50}{4} = 12.5[/tex]
So
[tex]y = 12.5x + b[/tex]
L (5) = 100
So [tex]y(5) = 100[/tex], which means that when [tex]x = 5, y = 100[/tex], and we use this to find b.
[tex]y = 12.5x + b[/tex]
[tex]100 = 12.5*5 + b[/tex]
[tex]b = 100 - 12.5*5[/tex]
[tex]b = 37.5[/tex]
So
[tex]L(x) = 12.5x + 37.5[/tex]
a. Determine the value of L (13)
L when [tex]x = 13[/tex]. So
[tex]L(13) = 12.5*13 + 37.5 = 200[/tex]
