Assume the random variable x is normally distributed with mean 50 and standard 7 deviation . Find the indicated probability.
Answers
In a normal distribution, the mean represents the center of the distribution and the standard deviation represents the spread of the distribution.
The higher the standard deviation, the more spread out the data is. The probability of a specific outcome occurring is given by the area under the curve of the normal distribution that corresponds to that outcome.
For example, if we wanted to find the probability of x being between 45 and 55, we would find the area under the normal curve between those two values. This can be done using a table of standard normal probabilities or by using a calculator or statistical software.
In general, if we know the mean and standard deviation of a normally distributed random variable, we can use that information to find probabilities for specific outcomes or ranges of outcomes.
you'll need to provide a specific range or value of X. Once you have that, you can use the Z-score formula or a standard normal distribution table to determine the probability.

Which graph of ordered pairs shows a proportional relationship? On a coordinate plane, points (1, negative 2) and (2, negative 4) are plotted. On a coordinate plane, points (negative 2, negative 2) and (1, 3) are plotted. On a coordinate plane, points (negative 2, 1) and (1, negative 2) are plotted. On a coordinate plane, points (2, 1) and (4, 3) are plotted.
Answers
The graph of ordered pairs that shows a proportional relationship is the one that plots the points (2, 1) and (4, 3) on a coordinate plane.
Determine the proportional relationship:To determine the proportional relationship, calculate the ratios of the change in the y-coordinates to the change in the x-coordinates for each pair of points.
Here we have 4 sets of points
The ratios of the points can be calculated as follows
For the first set of points (1, -2) and (2, -4):
change in y-coordinate = -4 - (-2) = -2
change in x-coordinate = 2 - 1 = 1
ratio = (-2) / 1 = -2
For the second set of points (-2, -2) and (1, 3):
change in y - coordinate = 3 - (-2) = 5
change in x - coordinate = 1 - (-2) = 3
ratio = 5 / 3
For the third set of points (-2, 1) and (1, -2):
change in y-coordinate = -2 - 1 = -3
change in x-coordinate = 1 - (-2) = 3
ratio = (-3) / 3 = -1
For the fourth set of points (2, 1) and (4, 3):
change in y-coordinate = 3 - 1 = 2
change in x-coordinate = 4 - 2 = 2
ratio = 2 / 2 = 1
The only set of points that has a constant ratio for the change in y-coordinates to the change in x-coordinates is the fourth set of points
(2, 1) and (4, 3).
Therefore,
The graph of ordered pairs that shows a proportional relationship is the one that plots the points (2, 1) and (4, 3) on a coordinate plane.

How many cards did Julie give Kim.
Answers
Answer:
1155
Step-by-step explanation:
Total number of cards is 2730+3570=6300
Since Kim now has 3 times the card of Julie so Julie must have 6300/4=1575.
So, Julie gave 2730-1575=1155
Answer:
1155 cards
Step-by-step explanation:
3(2730-x)=3570+x
8190 - 3x = 3570 + x

1 2 3 4 5 6 7 8 9 10
Answers
Answer:
The approximate number of people that could fit in the 1 mile stretch is 145,200 people
Step-by-step explanation:
The length of the street = 1 mile stretch
The width of the street = 45 ft
The depth of each sidewalk = 5 ft
1 mile = 5,280 ft
Therefore;
The area of the side walk on each side of the street = 5 × 5,280 = 26,400 ft²
The area of both side walks = 26,400×2 = 52,800 ft²
The area of the street = 45 × 5,280 = 237,600 ft²
The total area of the street = The area of the street + The area of both side walks = 237,600 ft² + 52,800 ft²
The total area of the street = 290,400 ft²
The area occupied by one person is at least 2 ft²/person
Therefore, the approximate number of people that could fit in the 1 mile stretch = (The total area of the street)/(The area occupied by one person)
The approximate number of people that could fit in the 1 mile stretch = 290,400 ft²/(2 ft²/person) = 145,200 people
The approximate number of people that could fit in the 1 mile stretch = 145,200 people.

*f(x)-b shifts the function b units downward
f(x+b) shifts the function b units to the left
f(x-b) shifts the function b units to the right
-f(x) reflects the function in the x-axis.
By this, we can say that g(x) is 3 units upward f(x). h(x) is 4 units upward f(x).
k(x) is 1 unit downward f(x).

An experimenter would like to construct a 99% confidence interval with a width at most 0. 5 for the average resistance of a segment of copper cable of a certain length. If the experimenter knows that the standard deviation of such resistances is 1. 55. How big a sample should the experimenter take from the population? what happens if the standard deviation and the width of the confidence interval are both doubled?.
Answers
A big sample that should the experimenter take from the population is 256 and if the standard deviation and the width of the confidence interval are both doubled then the sample is also 256.
In the given question,
The confidence level = 99%
Given width = 0.5
Standard deviation of resistance(\sigma)= 1.55
We have to find a big sample that should the experimenter take from the population and what happens if the standard deviation and the width of the confidence interval are both doubled.
The formula to find the a big sample that should the experimenter take from the population is
Margin of error(ME) \(=z_{\alpha /2}\frac{\sigma}{\sqrt{n}}\)
So n \(=(z_{\alpha /2}\frac{\sigma}{\text{ME}})^2\)
where n=sample size
We firstly find the value of ME and \(z_{\alpha /2}\).
Firstly finding the value of ME.
ME=Width/2
ME=0.5/2
ME=0.25
Now finding the value of \(z_{\alpha /2}\).
Te given interval is 99%=99/100=0.99
The value of \(\alpha\) =1−0.99
The value of \(\alpha\) =0.01
Then the value of \(\alpha /2\) = 0.01/2 = 0.005
From the standard table of z
\(z_{0.005}\) =2.58
Now putting in the value in formula of sample size.
n=\((2.58\times\frac{1.55}{0.25})^2\)
Simplifying
n=(3.999/0.25)^2
n=(15.996)^2
n=255.87
n≈256
Hence, the sample that the experimenter take from the population is 256.
Now we have to find the sample size if the standard deviation and the width of the confidence interval are both doubled.
The new values,
Standard deviation of resistance(\(\sigma\))= 2×1.55
Standard deviation of resistance(\(\sigma\))= 3.1
width = 2×0.5
width = 1
Now the value of ME.
ME=1/2
ME=0.5
The z value is remain same.
Now putting in the value in formula of sample size.
n=\((2.58\times\frac{3.1}{0.5})^2\)
Simplifying
n=(7.998/0.5\()^2\)
n=(15.996\()^2\)
n=255.87
n≈256
Hence, if the standard deviation and the width of the confidence interval are both doubled then the sample size is 256.

Given collinear points E, F and G such that point F is the midpoint of segment EG. Find the new length of EG given that EF =5x+9 and FG = 3x +17
Answers
Answer:
The length of EG is 58 units
Step-by-step explanation:
The midpoint of a segment divides it into two equal part
Let us use this rule to solve our question
∵ E, F, and G are collinear points
∵ Point F is the midpoint of segment EG
→ That means F divides EG into 2 equal segments EF and FG
∴ EF = FG
∵ EF = 5x + 9
∵ FG = 3x + 17
→ Equate them
∴ 5x + 9 = 3x + 17
→ Subtract 3x from both sides
∵ 5x - 3x + 9 = 3x - 3x + 17
∴ 2x + 9 = 17
→ Subtract 9 from both sides
∴ 2x + 9 - 9 = 17 - 9
∴ 2x = 8
→ Divide both sides by 2 to find x
∵ \(\frac{2x}{2}=\frac{8}{2}\)
∴ x = 4
→ Substitute x by 4 in EF and FG to find their lengths
∵ EF = 5(4) + 9 = 20 + 9 = 29
∵ FG = 3(4) + 17 = 12 = 17 = 29
∵ EG = EF + FG
∴ EG = 29 + 29 = 58
∴ The length of EG is 58 units

a top hat contains 3 red chips and 2 green chips. chips are drawn randomly, one at a time without replacement, until all 3 of the reds are drawn or until both green chips are drawn. what is the probability that the 3 reds are drawn?
Answers
The probability that the 3 reds are drawn is 2/5.
Five chips are arranged at random, and the chips are then taken starting from the left to the right. We solve for \($\binom{5}{2} = 10$\) to see how many ways there are to arrange the three red chips and the two green chips. We have found, however, that whenever the final red chip is drawn, we take the first two green chips. In a similar manner, if the final chip is green, we choose all three red chips before the final chip. This implies that in all possible outcomes, the final chip must be green.
As a result, we must determine how many ways there are to arrange three red chips and one green chip, which is \($\binom{4}{3} = 4$\). The answer is \($\boxedtextbf(B) \frac{2}{5}$\) since a green chip will be the last 4 out of the 10 situations.

The given identities can be verified using basic rules of exponentials and algebra. Here are the steps to verify the given identities:
(a) 1 = ∑_(n=1) ^∞▒〖10^(x)+2(-1) ^nln(x)〗0
Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n. ∑_(n=1)^∞▒10^(x) = 10^x+10^x+...= (2/3) (10^x) (odd terms only)∑_(n=1)^∞▒〖(-1)^nln(x)〗= ln(x)-ln(x)+ln(x)-ln(x)+...= (0) (even terms only)
Thus, we have 1= (2/3) (10^x) + (0) = (2/3) (10^x) (b) e^x = ∑_(n=1) ^∞▒〖10^x+2n(x)〗
Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n.
∑_(n=1) ^∞▒10^(x) = 10^x+10^x+...= (1/2) (10^x) (even terms only) ∑_(n=1) ^∞▒〖2n(x)〗= 2(x)+2(2x) +2(3x) +...= 2x (1+2+3+...) = -x/(-1) ^2= -x
Thus, we have e^x= (1/2) (10^x) - x(c) e^(-x) = ∑_(n=1) ^∞▒〖10^x+2(-1) ^nln(x)〗0
We can use the same series from part (a) with x replaced by -x.
Thus, we have e^(-x) = (2/3) (10^(-x)) + (0) = (2/3) (1/10^x)
Similarly, e^x= (2/3) (10^x) Subtracting these two equations, we get: e^x - e^(-x) = (2/3) (10^x + 1/10^x) (answer) (d)
Cosh x = ∑_(n=0) ^∞▒〖10^x+2n(x)〗
Similar to part (b), we have two series, one for even values of n, and one for odd values of n.∑_(n=0)^∞▒10^(x) = 1+10^x+10^x+...= (1/2) (10^x) (even terms only)∑_(n=0)^∞▒〖2n(x)〗= 0+2x+2(2x)+2(3x)+...= 2x (1+2+3+...)= 2x(1/(-1)^2)= 2xThus, we have Cosh(x) = 1 + (1/2) (10^x) + 2x (e^x)(e^x - e^(-x)) / 2= 1 + (1/2) (10^x) + 2x (1 + (2/3) (10^x + 1/10^x)) (answer)(e) Sinh x = ∑_(n=1)^∞▒〖2^(2n-1)(x)〗
Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n.∑_(n=1)^∞▒〖2^(2n-1)(x)〗= 2x+2^3x+2^5x+...= 2x(1+2^2+2^4+...)= 2x(2^0+2^2+2^4+...)= 2x(1/ (1-2^2))= -2x/3Thus, we have Sinh(x) = ∑_(n=1)^∞▒〖2^(2n-1)(x)〗= 2x/3 (answer)
