Use normal approximation to estimate the probability of getting more than 52 girls in 100 births. Assume that boys and girls are equally likely.
The probability of getting more than 52 girls in 100 births is 0.3446
This is further explained below.
What is the probability?Generally, The ratio of females to boys per one hundred births is modeled here as:
[tex]\large X \sim Bin(n = 100, p = 0.5)[/tex]
Where
Bin shows binomial
n=sample size
p=sample proportion
The following is an approximation of this using the normal distribution:
[tex]\large X \sim N(\mu= np, \sigma^2 = np(1-p))\\\\\large X \sim N(\mu= 100*0.5 , \sigma^2 = 100*0.5*0.5)\\\\\large X \sim N(\mu= 50 , \sigma^2 = 25)\\\\\large X \sim N(\mu= 50 , \sigma = 5)[/tex]
In light of this, the formula for calculating the probability is as follows:
P(X > 52)
When we take into account the continuity correction factor, we obtain the following:
P(X > 52.5)
After transforming it into a regular variable according to the standards, the following is what we get:
P(Z > (52.5 - 50) / 5)
= P(Z > 0.5)
Taking this information from the usual normal tables, we get the following:
P(Z > 0.5) = 0.3085
in conclusion, the necessary probability in this scenario is 0.3085. It should be noted that we may do this without correcting the continuity, in which case:
P(X > 52)
[tex]= P(Z > (\frac{52 - 50}{ 5})[/tex]
= P(Z > 0.4)
= 0.3446
Hence, the necessary probability in this scenario is 0.3446.

Consider the first five terms of the following sequence
-5, -10, -20, -40, -80, ...
If the sequence defines a function, what is a reasonable domain and range of the function?
PLS HELP!!
A reasonable domain and range of the function is as follows:
Domain = {1, 2, 3, 4, 5, ....}Range = {-5, -10, -20, -40, -80, ....}What is a domain?A domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values (numbers) to a function and the domain of a graph comprises all the input numerical values which are shown on the x-axis.
By critically observing the given sequence, we can reasonably and logically deduce that it follows the following function rule:
f(x) = -5(2)^{x - 1}
When x = 1, we have:
f(x) = -5(2)^{1 - 1}
f(x) = -5(2)^{0}
f(x) = -5
When x = 2, we have:
f(x) = -5(2)^{2 - 1}
f(x) = -5(2)^{1}
f(x) = -10
When x = 3, we have:
f(x) = -5(2)^{3 - 1}
f(x) = -5(2)^{2}
f(x) = -5(4)
f(x) = -20
When x = 4, we have:
f(x) = -5(2)^{4 - 1}
f(x) = -5(2)^{3}
f(x) = -5(8)
f(x) = -40
When x = 5, we have:
f(x) = -5(2)^{5 - 1}
f(x) = -5(2)^{4}
f(x) = -5(16)
f(x) = -80
Therefore, a reasonable domain and range of the function is given by:
Domain is equal to {1, 2, 3, 4, 5, ....}
Range is equal to {-5, -10, -20, -40, -80, ....}

Is it possible to perform two reflections of an object so that the final image is identical to the original image? If so, give an example. If not , explain your reasoning
Answer:
Yes, it is possible
Step-by-step explanation:
Take a function y= f(x). When it is reflected across the x-axis the x-coordinates do not change but the y coordinates become the negative of the pre-image
In other words reflection f'(x) of f(x) over the x-axis is y = -f(x)
If we reflect f'(x) over the x-axis then the resultant reflection is
f''(x) = -f'(x) = -(-f(x)) = f(x)
So we get the original image after two consecutive reflections along the x-axis

A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming. Which statement best describes the depth of the fish, given this equation?
A. From the starting position of 7 meters below sea level, the fish is descending 3 meters per second.
B. From the starting position of 7 meters below sea level, the fish is ascending 3 meters per second.
C. From the starting position of 3 meters below sea level, the fish is descending 7 meters per second.
D. From the starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
The statement that best describes the depth of the fish based on the given equation is: C. From the starting position of 3 meters below sea level, the fish is descending 7 meters per second.
How to Interpret a Linear Equation?A negative slope implies a negative constant rate of a linear equation. In slope-intercept form, the linear equation is expressed as y = mx + b, where the constant rate is represented as "m", while the starting value is represented as "b".
In the given scenario, the equation y = -7x - 3 models the depth, y, the fish swims below the sea level at x number of seconds.
This implies that:
The starting value (b) = -3, represents the starting position of the fish, which is 3 meters below the sea level.
-7 is the constant rate of the linear equation, which is the rate at which the fish is descending below the sea level, which is: 7 meters per second. The best statement is therefore: C.

A) 2
B) -2
C) -1/2
D) 1/2
Answer:
A
Step-by-step explanation:
the slope of the line is a measure of the rate of change.
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (2, 5) ← 2 points on the line
m = [tex]\frac{5-(-3)}{2-(-2)}[/tex] = [tex]\frac{5+3}{2+2}[/tex] = [tex]\frac{8}{4}[/tex] = 2
the rate of change of y with respect to x is 2
Answer:
A) 2
Step-by-step explanation:
Rise over run,
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1}}[/tex]
-2 will be [tex]x_{1}[/tex] and -3 will be [tex]y_{1}[/tex]
2 will be [tex]x_{2}[/tex] and 5 will be [tex]y_{2}[/tex]
It doesn't matter which order you place the points, for [tex]x_{1}[/tex], or [tex]x_{2}[/tex] but [tex]x_{1}[/tex] and and [tex]y_{1}[/tex] must be one point while [tex]x_{2}[/tex] and [tex]y_{2}[/tex] must be one point.
Then, we replace the values to find:

Another music store rents trombones for $30 per month plus a yearly fee of $48. Which deal is better? Should Maria change her rental plan? Part A: Maria needs a trombone for only 12 months. Renting the trombone costs $34 per month. She can buy the trombone for $495. Should she buy or rent the trombone? Explain. How much does she pay? dont have to answer part a but u can if u want i only put it there so u can see it all, thank you friend: )
Answer:
Yearly fee of $48 is better
Step-by-step explanation:
It is obvious. We know that a year have 12 months so if we compare between the $30 per months deal (which is $360 a year when we multiple it with 12) and the $48 a year deal, the difference is $312 which is a lott.
If Maria only want to use it for a month then its fine but if she want to use it more than 1 month, she definitely should choose the no 2 deal because if she even only rent it for 2 months using the no 1 deal ($30+$30=$60), the no 2 deal ($48) is far more better with a $12 difference.
Part A: Just like the top we know that its costs $34 per month and we need to know how much it would costs for 12 months/a year. So we just have to multiple it with 12=$408. Now which is better $495 or $408? Of course its $408 right? Maria could save $87 with renting the trombone than buying the trombone.

12. Luis bought stock at $83.60. The next day, the price changed by -4 3/4 What
was the final stock price?
The final stock price will be equal to $87.57.
Percentage may be defined as a form of expressing a number as a fraction of hundred. To find the percentage of a number we divide the number by the total amount and then multiply the answer with hundred. We have the initial value of stock price as $83.60, and the stock price changed by 4.75%. Now, if we find 4.75% 0f $83.60 we get
(4.75/100) × $83.60 = $3.97 which is the change occurring in price. We add this amount in the initial amount and we get $83.60 + $3.97 = $87.57. If we look at the initial and final amount of stock, we see that Luis benefitted from the stock as he gained an amount of $3.97.

What kind of transformation converts the graph of f(x)=3x+9 into the graph of g(x)=3x–10?
The transformation of the functions from f(x) to g(x) is translate 7 units right and 2 units up
How to determine the transformation?The equations of the functions are given as
f(x) = 3x + 9
g(x) = 3x - 10
Let the translations from f(x) to g(x) be h and k
So, we have
g(x) = f(x + h) + k
This gives
f(x + h) = 3(x + h) + 9 + k
Open the brackets
f(x + h) = 3x + 3h + 9 + k
Substitute f(x + h) = 3x + 3h + 9 + k in g(x) = f(x + h) + k
g(x) = 3x + 3h + 9 + k
This means that
3x + 3h + 9 + k = 3x - 10
Evaluate the like terms
3h + 9 + k = - 10
This gives
3h + k = - 19
Express -19 as -21 + 2
3h + k = -21 + 2
Express 21 as 3 * 7
3h + k = -3 * 7 + 2
By comparison, we have
h = -7 and k = 2
This means that the transformation is 7 units right and 2 units up

Using the graph, where the vertical axis represents ounces of food and horizontal axis represents the days bag was bought,
a. It took 24 days for the cat food to be 16 ounces
b. The weight of the bag before it was opened is 56 ounces,.
How to solve graphs?The graph represents the number of ounces of cat food that were left in the bag and the days it was bought.

Imagine that 1 in 5 individuals is allergic to peanuts. A peanut allergy test gives a positive result 10% of the time. If someone has a peanut allergy, the test will give a positive result 40% of the time. What is the probability that you have a peanut allergy if the test result is positive?.
The probability that you have a peanut allergy given a positive test result is 50%.
To find the probability that you have a peanut allergy given a positive test result, we can use Bayes' theorem.
Let's define the following events:
A: You have a peanut allergy.
B: The test result is positive.
We are given the following probabilities:
P(A) = 1/5 = 0.2 (1 in 5 individuals is allergic to peanuts).
P(B|A) = 0.4 (if you have a peanut allergy, the test will give a positive result 40% of the time).
P(B|not A) = 0.1 (if you don't have a peanut allergy, the test will give a positive result 10% of the time).
We want to find P(A|B), which is the probability that you have a peanut allergy given a positive test result.
Bayes' theorem states:
P(A|B) = (P(B|A) × P(A)) / P(B)
Now, let's calculate P(B):
P(B) = P(B|A) × P(A) + P(B|not A) × P(not A)
P(not A) is the probability of not having a peanut allergy, which is equal to 1 - P(A):
P(not A) = 1 - P(A) = 1 - 0.2 = 0.8
Now, we can calculate P(B):
P(B) = (0.4 × 0.2) + (0.1 × 0.8) = 0.08 + 0.08
= 0.16
Now, let's calculate P(A|B) using Bayes' theorem:
P(A|B) = (P(B|A) × P(A)) / P(B)
P(A|B) = (0.4 × 0.2) / 0.16
P(A|B) = 0.08 / 0.16
P(A|B) = 0.5
Therefore, the probability that you have a peanut allergy given a positive test result is 50%.
