Following the prescription, You will need to administer a 0.7 tablespoon per dose.
Determining the number of tablespoons by using equivalent expressions?We can determine the number of tablespoons that are administered by using equivalent expressions.
From the standard conversion rate, we know that:
1 ml = 0.067628 tbsp15 ml = 1.01442 tbspUsing equivalent expressions:
7.5 mg/1.01442 tbsp = 5 mg/x tbsp
x = (1.01442 × 5)/7.5 tbsp
x = 0.67 tbsp
x = 0.7 tbsp per dose.

The number of calls received by an office on Monday morning between 8:00 AM and 9:00 AM has a mean of 6. Calculate the probability of getting at least 5 calls between eight and nine in the morning. Round your answer to four decimal places.
The probability of getting at least 5 calls between eight and nine in the morning is 0.8009.
How to calculate the probability?The probability of getting at least 5 calls between eight and nine in the morning will be:
= 1 - [P(x = 0) + P(x = 1)]
= 1 - (e^-3(1 + 3]
= 1 - 0.19915
= 0.8009
Therefore, the probability of getting at least 5 calls between eight and nine in the morning is 0.8009.

The explicit formula for the arithmetic sequence is: [tex]P_n = 30 + 25n[/tex]
Using the formula, we have that [tex]P_{100} = 2530[/tex].
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
From the recursive formula, we have that:
[tex]a_1 = 30 + 25 = 55, d = 25[/tex]
Hence the explicit formula is:
[tex]P_n = 55 + 25(n-1)[/tex]
[tex]P_n = 30 + 25n[/tex]

In major league baseball, a no-hitter is a game in which a pitcher, or pitchers, doesn't give up any hits throughout the game. No-hitters occur at a rate of about three per season. Assume that the duration of time between no-hitters is exponential. What is the probability that an entire season elapses with a single no-hitter? If an entire season elapses without any no-hitters, what is the probability that there are no no-hitters in the following season? What is the probability that there are more than 3 no-hitters in a single season?
Using the Poisson distribution, it is found that:
There is a 0.0498 = 4.98% probability that an entire season elapses with a single no-hitter.If an entire season elapses without any no-hitters, there is a 0.0498 = 4.98% probability that there are no no-hitters in the following season.There is a 0.3528 = 35.28% probability that there are more than 3 no-hitters in a single season.What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.The average rate is of 3 no-hitters per season, hence:
[tex]\mu = 3[/tex].
The probability that an entire season elapses with a single no-hitter is P(X = 0), hence:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-3}3^{0}}{(0)!} = 0.0498[/tex]
There is a 0.0498 = 4.98% probability that an entire season elapses with a single no-hitter.
Seasons are independent, hence:
If an entire season elapses without any no-hitters, there is a 0.0498 = 4.98% probability that there are no no-hitters in the following season.
The probability that there are more than 3 no-hitters in a single season is P(X > 3) given as follows:
[tex]P(X > 3) = 1 - P(X \leq 3)[/tex]
In which:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
Then:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-3}3^{0}}{(0)!} = 0.0498[/tex]
[tex]P(X = 1) = \frac{e^{-3}3^{1}}{(1)!} = 0.1494[/tex]
[tex]P(X = 2) = \frac{e^{-3}3^{2}}{(2)!} = 0.2240[/tex]
[tex]P(X = 3) = \frac{e^{-3}3^{3}}{(3)!} = 0.2240[/tex]
Then:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0498 + 0.1494 + 0.2240 + 0.2240 = 0.6472[/tex]
[tex]P(X > 3) = 1 - P(X \leq 3) = 1 - 0.6472 = 0.3528[/tex]
There is a 0.3528 = 35.28% probability that there are more than 3 no-hitters in a single season.

The length, l call my a rectangular room is four less than the width, W, of the room. Which expression represents the area of the room.
(I have no options)
Answer: Either [tex]w(w-4)[/tex] or [tex]w^2 - 4w[/tex]
==================================================
Explanation:
w = width
w-4 = length since it is 4 less than the width
Multiply the length and width to get the area of the rectangle.
area = length*width
area = [tex](w-4)w[/tex]
area = [tex]w(w-4)[/tex]
area = [tex]w^2-4w[/tex]
In the last step, I used the distributive property.
Either expression mentioned above is valid for the area. If you had to pick only one, I'd go for [tex]w^2-4w[/tex]

A cone of height 9cm has a volume of ncm³ curved surface area of ncm². Find the vertical angle of the cone
Answer:
Step-by-step explanation:
let the radius be r and the slant height be L
then first of all: L^2 = r^2 + 9^2
= r^2 + 81
Surface area = πrL = n
volume = (1/3)πr^2 (9) = 3πr^2 = n
then 3πr^2 = πrL
3r = L , then in L^2 = r^2 + 81
9r^2 = r^2 + 81
8r^2 = 81
r = 9/√8
L^2 = 81/8 + 81 = 729/8
L = √1458/4

A survey found that women's heights are normally distributed with mean 62.7 in, and standard deviation 2.8 in. The survey also found that men's heights are normally distributed with mean
69.3 in. and standard deviation 3.9 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 55 in, and a maximum of 62 in. Complete
parts (a) and (b) below.
a. Find the percentage of men meeting the height requirement. What does the result suggest about the genders of the people who are employed as characters at the amusement park?
The percentage of men who meet the height requirement is %.
(Round to two decimal places as needed)
Using the normal distribution, we have that:
The percentage of men who meet the height requirement is 3.06%. This suggests that the majority of employees at the park are females.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation of men's heights are given as follows:
[tex]\mu = 69.3, \sigma = 3.9[/tex].
The proportion of men who meet the height requirement is is the p-value of Z when X = 62 subtracted by the p-value of Z when X = 55, hence:
X = 62:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{62 - 69.3}{3.9}[/tex]
Z = -1.87
Z = -1.87 has a p-value of 0.0307.
X = 55:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{55 - 69.3}{3.9}[/tex]
Z = -3.67
Z = -3.67 has a p-value of 0.0001.
0.0307 - 0.0001 = 0.0306 = 3.06%.
The percentage of men who meet the height requirement is 3.06%. This suggests that the majority of employees at the park are females.
