Miss Kent reminds her students that every two inches on the model represents 25 feet on the actual statue. Based on Martina's measurements what is the area in square feet of the tablet on the actual Statue of Liberty show your work
Answer:
78.125 ft²
Step-by-step explanation:
The dimension of the tablet is given as:
Length = 1 in
Width = ½ in
First,we need to determine the measurements in feet.
Using the scale measurement:
Scale: 2 in =25 ft
Divide both sides by 2
2 in/2 = 25 ft/2
1 in = 12.5 ft
So, Length = 12.5 ft
Divide the scale measurement by 4
2 in/4 = 25 ft/4
½ in = 6.25 ft
So,
Width = 6.25 ft
Area is calculated as:
Area = Length * Width
Area = 12.5 ft * 6.25 ft
Area = 75.125 ft²

89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3
64.4 53.7 63.4 46.2 63.0 92.1 57.6
A) Calculate the values of the mean and standard deviation (in mL).
mean 59.222 mL
standard deviation 16.725 mL
Interpret the values of the mean and standard deviation.
A typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.
B) The mean amount poured into a tall, slender glass for individuals asked to pour 44.3 mL (1.5 ounces) was 51.283 mL. What do the values of the means for the two types of glasses suggest about the shape of glasses used?
The mean amount for a short, wide glass is greater than the mean amount for a tall, slender glass. This suggests that bartenders tend to pour more into a short, wide glass compared to a tall, slender glass.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data below :
x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6
Mean(m) = ΣX / n
ΣX = 1066 ; n = number of observations = 18
Mean(m) = 1066 / 18
Mean = 59.22
Standard deviation (σ) :
Using the online standard deviation calculator :
σ = √(Σ(x - m)²/n-1)
σ = √264.198395
σ = 16.72
The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.
typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.
(59.22 - 19.7) mL = 39.52mL
Mean amount poured into a tall slender glass = 51.283
Mean (short wide glass) = 59.22mL
Mean (tall slender glass) = 51.283mL
Short wide glass > tall slender glass

Write the equation of a line perpendicular to 6y-2x=-8 and passes through the point(-2,1) in slope-
intercept form
Answer:
y = -3x + 17/10
Step-by-step explanation:
First you want to move the 2x to the other side of the equal sign for the proper way of slope-intercept form. Which makes it 6y=2x-8.
You still want to make sure that y is by itself so you divide the whole equation by 6 which makes it y=1/3x-8/6.
We have to find the slope of the a perpendicular line now and to do so, you must take the slope of the given line and make it into the opposite reciprocal.
To do that you take 1/3 and reciprocate it, which makes it 3.
Then flip the sign to make it opposite. Like making a positive into a negative and a negative into a positive. Therefore the slope of the perpendicular line is -3.
Now we must make it past through point (-2,1). To do that you have to adjust the y-intercept. Because of that, the y-intercept is 1.7 or 17/10.
The equation of the slope is y=-3x+17/10

Answer:
[tex]=256x^8y^{20}[/tex]
Step-by-step explanation:
We have the expression:
[tex](4x^2y^5)^4[/tex]
We can use the power of a product property:
[tex](ab)^x=a^xb^x[/tex]
This yields:
[tex]=(4)^4\cdot(x^2)^4\cdot(y^5)^4[/tex]
We can evaluate 4 to the fourth:
[tex]=256(x^2)^4\cdot(y^5)^4[/tex]
Now, we can use the power of a power property:
[tex](x^a)^b=x^{ab}[/tex]
So:
[tex]=256(x^{2(4)})(y^{5(4)})[/tex]
Multiply:
[tex]=256x^8y^{20}[/tex]
And we're done!
Answer:
256x^8 y^20
that's the answer I got when I simplified it

You may have polarized sunglasses that eliminate glare by polarizing the light. When light is polarized, all of the waves are traveling in parallel planes. Suppose vertically polarized light with intensity Io strikes a polarized filter with its axis at an angle of θ with the vertical. The intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It. If θ, write It as a function of Io,
Answer:
lt = lo/cos²θStep-by-step explanation:
Given the intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It, we are to write lt as a function of lo
Given the equation
Cosθ= √ Io/It
Let us make lt the subject of the formula;
square both sides of the equation
(Cosθ)²= (√ Io/It)²
cos²θ = lo/lt
cross multiply
ltcos²θ = lo
divide both sides by cos²θ
ltcos²θ/ cos²θ= lo/cos²θ
lt = lo/cos²θ
Hence the expression of lt as a function of lo is lt = lo/cos²θ

The switchboard in a Denver law office gets an average of 8.2 incoming phonecalls during the noon hour on Thursdays. Find the probability that more than 4 calls will be received during the noon hour, on some particular Thursday. Assume calls are independent of each other.
Answer:
The probability that more than 4 calls will be received during the noon hour, on some particular Thursday is 0.9113.
Step-by-step explanation:
The random variable X can be defined as the number of incoming phone calls during the noon hour on Thursdays.
The random variable X describes a finite number of occurrences of an event in a fixed time interval.
The random variable X follows a Poisson distribution with parameter λ = 8.2.
The probability mass function of X is:
[tex]P(X=x)=\frac{e^{-8.2}(8.2)^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability of more than 4 calls as follows:
[tex]P(X>4)=1-P(X\leq 4)[/tex]
[tex]=1-\sum\limits^{4}_{x=0}{\frac{e^{-8.2}(8.2)^{x}}{x!}}\\\\=1-[0.00027+0.00225+0.00923+0.02524+0.05174]\\\\=1-0.08873\\\\=0.91127\\\\\approx 0.9113[/tex]
Thus, the probability that more than 4 calls will be received during the noon hour, on some particular Thursday is 0.9113.
Simplify.

Step-by-step explanation:
A contractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. State rules do not allow a contractor to be offered more than one of these jobs. If this contractor is awarded any of these jobs, the profits earned from these contracts are $10 million from the office building, $5 million from the theater, and $2 million from the parking garage. His profit is zero if he gets no contract. The contractor estimates that the probabilities of getting the office building contract, the theater contract, the parking garage contract, or nothing are .15, .30, .45, and .10, respectively.
1. Write the probability distribution of x .
2. Find the mean and standard deviation of x .
Answer:
The probability distribution of x is
Profits in millions (x) Probability of getting contract (P(x))
$10 0.15
$ 5 0.30
$ 2 0.45
$ 0 0.10
The mean is [tex]E(X) = 3.9 millions [/tex]
The standard deviation is [tex]s = 3.01 \ millons [/tex]
Step-by-step explanation:
Generally the probability distribution of x is
Profits in millions (x) Probability of getting contract (P(x))
$10 0.15
$ 5 0.30
$ 2 0.45
$ 0 0.10
Generally the mean is mathematically represented as
[tex]E(X) = x * p(x)[/tex]
=> [tex]E(X) = [10 * 0.15 ] + [5 *0.30 ] + [2 * 0.45 ] + [0 * 0.10] [/tex]
=> [tex]E(X) = 3.9 millions [/tex]
Now
[tex] E(X^2) = x^2 * p(x)[/tex]
=> [tex] E(X^2) = (10 ^2 * 0.15) + (5 ^2 * 0.30) +(2 ^2 * 0.45) + (0 * 0.10)[/tex]
=> [tex] E(X^2) = 24.3 [/tex]
Gnerally the variance is mathematically represented as
[tex]V(X) = E(X^2) - [E(X)]^2[/tex]
=> [tex]V(X) = 24.3 - 3.9^2[/tex]
=> [tex]V(X) = 9.09 [/tex]
Gnerally the standard deviation is mathematically represented as
[tex]s = \sqrt{V(X)}[/tex]
=> [tex]s = \sqrt{9.09[/tex]
=> [tex]s = 3.01 [/tex]
Write the equation of a line with slope 3 and y-intercept −3.
