16 is a what percen of 200

The probability of getting more than 52 girls in 100 births is 0.3446

This is further explained below.

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.

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.

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.

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.

The solution of m for question 6 and the value of z for question 10 does not exist.

According to the question,

We have the following information,

6) 1/3 + 2m/3 = 2m/3-2/3

Now, moving the terms with the same variables in one side:

2m/3-2m/3+1/3 = -2/3

Now, when 2m/3 is subtracted from 2m/3 then we have no variable left.

So, the solution of this equation does not exist.

10) 2.5(2z+5) = 5(z+2.5)

Now, multiplying the numbers outside the bracket into bracket:

5z+12.5 = 5z+12.5

Moving the terms with the same variables on one side:

5z-5z+12.5 = 12.5

Now, when 5z is subtracted from5z then we have no variable left.

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%.

Answer:4 and 3

Step-by-step explanation:

A reasonable domain and range of the function is as follows:

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, ....}

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,.

The graph represents the number of ounces of cat food that were left in the bag and the days it was bought.

The vertical axis represents the ounces of cat food bought while the horizontal axis represents the days since the bag was bought.

Therefore, according to the graph, the days the bag takes to contain 16ounces of cat food can be calculated as follows:

According to the y-axis, the ounces of cat food reduces as the days goes by.

If you trace 16 ounces of cat food to the horizontal side, it shows it took 24 days for the cat food to be 16 ounces.

The amount the bag weigh before it was open should be on zero's days.

Therefore, the amount of bag is 56 ounces before it was opened.

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

The transformation of the functions from f(x) to g(x) is translate 7 units right and 2 units up

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
