The medical assistant weighs patients each month. Mrs. Smith weighed 120 pounds last month.
Over the last 2 months she gained 1½ and - pounds. What is Mrs. Smith's current weight?
13) 120 + 1.5 + 0.25 = 121.75 pounds
14) 4 - 1.5 = 2.5 pints
15) (2.25)(32)= $72
13. Mrs. Smith's current weight is 121.75 pounds.
14. The students should consume an additional 2.5 pints of water.
15. The nurse's overtime earnings amount to $72.00.
Given are words problems based on mixed numbers:
13. To find Mrs. Smith's current weight, we need to add the weight gained over the last two months to her weight last month.
Weight gained in the first month: 1 1/2 pounds
Weight gained in the second month: 1/4 pounds
Total weight gained over the last two months: 1 1/2 + 1/4 = 1 3/4 pounds
Now, to find Mrs. Smith's current weight, we add the total weight gained to her weight last month:
Current weight = Weight last month + Total weight gained
Current weight = 120 pounds + 1 3/4 pounds
Hence, Mrs. Smith's current weight is 121.75 pounds.
14. To calculate the additional water the students should consume to meet the school nurse's recommendation of at least 4 pints daily, we need to find the difference between the recommended amount and the average amount the students currently drink.
The recommended amount is 4 pints, and the average amount the students currently drink is 1 1/2 pints, which can be written as 1.5 pints.
Additional water needed = Recommended amount - Current average amount
Additional water needed = 4 pints - 1.5 pints
Additional water needed = 2.5 pints
Therefore, the students should consume an additional 2.5 pints of water daily to meet the school nurse's recommendation.
15. To calculate the nurse's overtime earnings, you can use the formula:
Overtime Earnings = Overtime Hours × Overtime Pay Rate
First, let's convert the mixed number of overtime hours into an improper fraction:
2 1/4 hours = 2 + 1/4 = 9/4 hours
Now, we can calculate her overtime earnings:
Overtime Hours = 9/4 hours
Overtime Pay Rate = $32.00/hour
Overtime Earnings = (9/4) hours × $32.00/hour
To simplify the calculation, you can convert the fraction to a decimal:
Overtime Earnings = (9/4) hours × $32.00/hour
Overtime Earnings = 2.25 hours × $32.00/hour
Overtime Earnings = $72.00
So, the nurse's overtime earnings amount to $72.00.

x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.For this problem, the parameters are given by:
p = 8/30 = 0.2667, n = 12.
Item a:
The probability is P(X = 2), hence;
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

The city has an average of 13 days of rainfall for April.
What is the probability of having exactly 10 days of precipitation in the month of April?
What is the probability of having less than three days of precipitation in the month of April?
What is the probability of having more than 15 days of precipitation in the month of April?
Using the Poisson distribution, we have that:
There is a 0.0859 = 8.59% probability of having exactly 10 days of precipitation in the month of April.There is a 0.00022 = 0.022% probability of having less than three days of precipitation in the month of April.There is a 0.2364 = 23.64% probability of having more than 15 days of precipitation in the month of April.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.For this problem, the mean is given as follows:
[tex]\mu = 13[/tex]
The probability of having exactly 10 days of precipitation in the month of April is P(X = 10), hence:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 10) = \frac{e^{-13}13^{10}}{(10)!} = 0.0859[/tex]
There is a 0.0859 = 8.59% probability of having exactly 10 days of precipitation in the month of April.
The probability of having less than three days of precipitation in the month of April is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
In which:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-13}13^{0}}{(0)!} \ approx 0[/tex]
[tex]P(X = 1) = \frac{e^{-13}13^{1}}{(1)!} = 0.00003[/tex]
[tex]P(X = 2) = \frac{e^{-13}13^{2}}{(2)!} = 0.00019[/tex]
Then:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0 + 0.00003 + 0.00019 = 0.00022
There is a 0.00022 = 0.022% probability of having less than three days of precipitation in the month of April.
For more than 15 days, the probability is:
P(X > 15) = P(X = 16) + P(X = 17) + ... + P(X = 20)
Applying the formula for each of these values and adding them, we have that P(X > 15) = 0.2364, hence:
There is a 0.2364 = 23.64% probability of having more than 15 days of precipitation in the month of April.

In the trapezoid below, AP = 6, PB = x + 3, CD = 2x + 6, AC = 10 and the area is 174. Find the value of x to the nearest tenth.
The value of x in the trapezoid given, to the nearest tenth, is: 10.5.
What is a Trapezoid?A trapezoid is a quadrilateral that has two sides only that are parallel to each other.
What is the Area of a Trapezoid?To find the area of a trapezoid, the formula used is expressed as: 1/2(a + b) × h, where:
a and b are length of the two base sides that are parallel.h is the height of altitude of the trapezoid.Given the following:
Area of trapezoid = 174 units²
AP = 6
PB = x + 3
CD = 2x + 6
AC = 10
Using the formula, we variables in the formula are:
a = AP + PB = 6 + x + 3 = x + 9
b = CD = 2x + 3
h = PC = √(AC² - AP²)
h = √(10² - 6²) = 8
Plug in the values into 1/2(a + b) × h:
174 = 1/2(x + 9 + 2x + 3) × 8
174 = 1/2(3x + 12) × 8
174 = (3x + 12) × 4
174 = 12x + 48
174 - 48 = 12x
126 = 12x
126/12 = x

Suppose that X is a random variable that has a binomial uncertainty distribution with parameters n = 10 and π = 0.4. Calculate the numerical value of the probability that X = 6. What are the numerical values of the mean and standard deviation of the uncertainty distribution?
The numerical values of the mean and standard deviation are 4 and 1.55, respectively
The numerical value of the probability that x = 6.The given parameters are:
n = 10
π = 0.4
The probability is then calculated as:
[tex]P(x) = ^nC_x * \pi^x *(1-\pi)^{n-x}[/tex]
So, we have:
[tex]P(6) = ^{10}C_6 * 0.4^6 *(1-0.4)^4[/tex]
Apply the combination formula
[tex]P(6) = \frac{10!}{6!4!} * 0.4^6 *0.6^4[/tex]
So, we have:
[tex]P(6) = 210 * 0.4^6 *0.6^4[/tex]
Evaluate
P(6) = 0.1115
Hence, the numerical value of the probability that x = 6 is 0.1115
The numerical values of the mean and standard deviationThe mean value is:
[tex]\bar x = n\pi[/tex]
This gives
[tex]\bar x = 10 * 0.4[/tex]
[tex]\bar x = 4[/tex]
The standard deviation value is:
[tex]\sigma = \sqrt{\bar x(1-\pi)[/tex]
This gives
[tex]\sigma = \sqrt{4(1-0.4)[/tex]
[tex]\sigma = 1.55[/tex]
Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively

Based on the angles of a + b and b + c, the value of b can be calculated to be 40°.
How many degrees is B?As this is a triangle, all the internal angles must add up to 180°.
This means that:

As we have the value of b + c, this becomes:
a + 100 = 180
a = 80°
b is therefore:
a + b = 120
80 + b = 120
b = 120 - 80
= 40 °
Full question is:
