Answer:
Pediatricians use numbers to calculate the patient's growth, they also use numbers to calculate the amount of liquid in a given shot or vaccine. Children's weight and height are measured in kilograms and centimeters. They also use math to change kilograms to pounds and centimeters to inches.
Step-by-step explanation:
Answer:
Conversions
Medications are prescribed using the metric system and Apothecary's Measure. The former uses grams and milliliters, while the latter is a medieval system using grains, scruples, drams, minims, fluid drams, fluid ounces, pints, quarts and gallons. Because the United States doesn't use the metric system, pediatricians must convert between these systems. Strong algebra skills are crucial, as mistakes in prescriptions can have catastrophic results.
Fractions
Much of a pediatrician's work involves taking accurate measurements. When measuring a patient's heart rate, pediatricians must know to divide the number of heart beats by the amount of time passed. They must know how to interpret blood pressure measurements, which are expressed as fractions. They may have to explain to a patient that body mass index, an important measure of health, is equal to his weight divided by his height squared. Equations
Specialists in pediatrics may require knowledge of more advanced mathematical concepts. Research pediatricians use math to analyze data for useful results. Those who work with complex internal systems, such as the cardiovascular system, use advanced equations and formulas to check on the status of organs. Pediatricians must also be able to communicate mathematical results to patients in language that is easily understood.
Other
Pediatricians regularly check the growth and development of patients. They develop growth charts, measure children's height and weight, and assess their overall development over time. They also use math to calculate how much medicine to administer in shots, measured in cubic centimeters or milliliters.

The length of a rectangle is 5 inches more than the width. The area is 33 square inches. Find the length and width . Round to the nearest tenth if necessary.
Answer:
the length and width . Round to the nearest tenth are 8.8 inches and 3.8 inches respectively.
Step-by-step explanation:
The area A of a rectangle is the product of the length L and width W. This may be expressed mathematically as
A = L * W
As such, given that the length is 5 inches more than the width,
L = W + 5
33 = W(W + 5)
W² + 5W - 33 = 0
Using the formula method which states that
s = -b±√(b²-4ac)/2a
W = -5 ± √5² - 4(1)(-33)/2
= -5 ± 12.53/2
= 7.53/2 (since length cannot be negative)
= 3.755 inches
L = 3.755 + 5
= 8.755 inches

Pete is a very good student . The probability that he studies for his test and then passes it is 7/10 If the probability that Pete studies is 7/8 find the probability that Pete passes his test? given that he studied.
Answer:
The probability that Pete passes his test given that he studied = (8/10) = (4/5) = 0.80
Step-by-step explanation:
Let the event that Pete studies be S.
Let the event that Pete passes the test be P.
The probability that he studies for his test and then passes it is P(S n P) = 7/10
The probability that Pete studies is P(S) = 7/8
The probability that Pete passes his test given that he studied = P(P|S)
The conditional probability, P(A|B) is given mathematically as
P(A|B) = P(A n B) ÷ P(B)
So, the required probability, P(P|S) will be
P(P|S) = P(P n S) ÷ P(S)
P(P n S) = P(S n P) = (7/10)
P(S) = (7/8)
P(P|S) = P(P n S) ÷ P(S)
= (7/10) ÷ (7/8)
= (7/10) × (8/7)
= (8/10) = (4/5) = 0.80
The probability that Pete passes his test given that he studied = (8/10) = (4/5) = 0.80

PLS HELP!! I’LL GIVE U 5 stars
Answer:
A). 81 students
B). 18 students
C). 10 students
Step-by-step explanation:
Let S = {All students of 8th grade} = 91
A = {Students in Art} = 68
B = {Students in band} = 31
Part A : A∪B = A + B - A∩B
A∪B = 68 + 31 - 18
A∪B = 81
A∪B represents the total number of students enrolled in art and band.
Part B : A∩B = 18
A∩B represents the number of common students enrolled in art and band.
Part C: ~(A∪B) = S - A∪B
~(A∪B) = 91 - 81
~(A∪B) = 10
~(A∪B) represents the number of students enrolled neither in art nor in band.

Figure the circumference of the tire: C=π×32 3.14×32=100.48=C
Divide the length of the mile by the circumference of the tire:. 63360/100.48 = 630.57 approximately.
Can somebody please tell me the answer to this
Answer:
x= 60°.
Step-by-step explanation:
To solve this problem, we must figure out the measure of the angles inside a hexagon. We can do this using the Interior Angle formula S = (n - 2)·180.
When we plug the number of sides a hexagon has into this equation, we get a total sum of 720.
To get the measure of each angle, we simply divide 720 by 6, giving us a measure of 120 per angle. Since we know the measure of the interior angles, we can solve for angles of the triangle using Supplementary angles.
180-120= 60°.
We know that the two angles of the triangle against the hexagon are 60°, but what about the other angle?
All you need to do is subtract the two angles from 180 to get you the angle of 'x'.
180-2(60°)= 60°.

Caleb went to Kroger and spent $83.47 on groceries. He had a coupon for $1.99 off bottled water and $0.89 off organic strawberries. How much did Caleb spend at Kroger?
Answer:
$86.35
Step-by-step explanation:
Total amount he spent at Kroger
= $83.47 on groceries. +coupon for $1.99 off bottled water + $0.89 off organic strawberries
= 83.47+0.89+1.99
= $86.35
Final answer:
After applying coupons for bottled water and organic strawberries, Caleb spent a total of $80.59 at Kroger. The discounts of $1.99 and $0.89 were subtracted from the initial spend of $83.47.
Explanation:
Caleb went to Kroger and initially spent $83.47 on groceries. He had two coupons: one for $1.99 off bottled water and another for $0.89 off organic strawberries. To calculate how much Caleb spent after using his coupons, we need to subtract the value of the coupons from the initial amount.
First, we calculate the total discount by adding the two coupon values:
$1.99 for bottled water
$0.89 for organic strawberries
Total discount = $1.99 + $0.89 = $2.88.
Then, we subtract this total discount from the initial spend:
$83.47 - $2.88 = $80.59
Therefore, Caleb spent $80.59 at Kroger after applying his coupons.
144 students enter a spelling bee, but only 1/6 of the group will make into the semi-final round, and only 2 /3 that group will make into the final round. How many students will enter the final round of the spelling bee?
Answer:
16 students
Step-by-step explanation:
144 students enter a spelling bee contest.
Step 1
For the semi final round we are told that only 1/6 of the group will make it into that round.
This is calculated as
1/6 × 144/students = 24 students.
This means that only 24 students would make it into the semi final rounds.
Step 2
We are also told in the question that only 2/3 of THAT group would make it into the final round.
" THAT" group been referred to in the question means the number students that made it to the semi final round
This is calculated as
2/3 of that group( the group that made it to the semi finals)
= 2/3 × 24 students
= 16 students.
Therefore, the number of students that will enter the final round of the spelling bee is 16 students.
To calculate the number of students who will make it to the final round of the spelling bee, we first determine the semi-finalists by multiplying the total students by 1/6, and then the number of finalists by multiplying the semi-finalists by 2/3, resulting in 16 students.
Explanation:To solve this problem, we first need to determine the number of students who will make it into the semi-final round. Since only 1/6 of the total students will make it to the semi-final round, we can calculate that by multiplying the total students (144) by 1/6, which results in 24 students.
Next, we need to calculate the number of students that will make it into the final round from the semi-final round. This means we need to multiply the semi-finalists (24) by 2/3, which results in 16.
Therefore, 16 students will make it into the final round of the spelling bee.

Answer:
6, -5/2, 7/4
Step-by-step explanation:
The required slope that shows given points are not collinear is 6, -5/2, and 7/4.
What is the slope of the line?
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
m = (y₂ - y₁) / (x₂ - x₁) - - - - (1)
Substitute points C(1, 1), and D(3, -4) in the above equation 1,
m = -4 -1 / 3 - 1
m = -5/2
Substitute points D(3, -4) and E(5, 8) in the above equation 1,
m = 8 + 4 / 5 - 3
m = 12 / 2
m = 6
Substitute points C(1, 1) and E(5, 8) in the above equation 1,
m = 8 - 1 / 5 - 1
m = 7 / 4
Thus, the required slope that shows given points are not collinear are 6, -5/2, and 7/4.

Eff scored a 23/25 on his math test, Maria scored 21/24 on her math test and Jake scored 17/20 on his math test. Who had the highest score? Explain how you know.
Answer:
Eff
Step-by-step explanation:
Fraction is a part of a whole, telling us how many parts of a whole we have. It can be converted to percentage or decimal.
Eff scored a 23/25 on his math test. Converting to percentage, eff score = 23/25 * 100% = 92%
Maria scored 21/24 on her math test. Converting to percentage:
Maria score = 21/24 * 100% = 87.5%
Jake scored 17/20 on his math test, converting to percentage:
Jake score = 17/20 * 100% = 85%
The person with the highest score has the highest percentage which is Eff with 92%.
Answer:
Eff had the highest score.
Step-by-step explanation:
The approach to determine who get the same score is converting each fraction to an arbitrary scale, which is 100 for this problem. Now, the conversions are presented below:
Eff
[tex]x = \frac{23}{25}\times 100[/tex]
[tex]x = 92[/tex]
Maria
[tex]x = \frac{21}{24}\times 100[/tex]
