The least common denominator of 2/5, 1/2, and 3/4 is:
Answer:
20
Step-by-step explanation:
20 is the least common denominator
2/5, 1/2, and 3/4 fractions have a Least Common Denominator of 20.
What is Least Common Denominator?The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
We have to determine the Least Common Denominator of fractions 2/5, 1/2, and 3/4
We need to calculate the factors of the denominators 5, 2, and 4.
⇒ 5 = 5 × 1
⇒ 2 = 2 × 1
⇒ 4 = 2 ×2 × 1
The LCD would be:
⇒ 5 × 2 ×2 × 1 = 20
Hence, 2/5, 1/2, and 3/4 fractions have a Least Common Denominator of 20.

In the accompanying diagram, PA is tangent to the circle at A and PC is a secant. If
PA = 8 and PB = 4, then BC =
Answer:
c. 12
Step-by-step explanation:
PA² = (BC + PB) × PB => tangent-secant theorem
PA = 8
PB = 4
BC = ?
Substitute
8² = (BC + 4) × 4
64 = 4BC + 16
64 - 16 = 4BC + 16 - 16
48 = 4BC
48/4 = 4BC/4
12 = BC
BC = 12

100 POINTS AND BRAINLIEST !!!!! (I need the answer ASAP) A school is planning to construct two rectangular play areas in the playground.
The length of play area A must be 1 foot longer than four times its width. The width of play area B must be 2 feet longer than the width of play area A, and the length must be 2 feet longer than three times its own width. In addition, the areas of the two play areas must be equal.
Write a system of equations to represent this situation, where y is the area of the play areas and x is the width of play area A. Which statement describes the number and viability of the system’s solutions?
A.
The system has two solutions, and both are viable because they result in positive widths.
B.
The system has only one solution, but it is not viable because it results in a negative width.

A photocopy machine was sold at 12% discount with 13% VAT. If the customer paid Rs. 3,57,984 then find VAT amount and discount amount.
Answer:
See the answers below
Step-by-step explanation:
Given data
Discount=12%
VAT= 13%
Amount paid= Rs. 3,57,984
The amount of VAT
=13/100*3,57,984
=0.13*357984
= Rs. 46537.92
The amount of discount
=12/100*3,57,984
=0.12*357984
= Rs. 42958.08
how do i find r in a geometric sequence of (243, 81, 27)? also how do i find the explicit formula for this?
Answer:
Step-by-step explanation:
The initial term is 243. Since it is a geometric sequence, each term is r times the preceding term.
r = 81/243 = ⅓
nth term = a₁rⁿ⁻¹ = 243(⅓)ⁿ⁻¹
Determine the value of c, given that the graph of f(x) = cx^2 + 1/x^2
has a point of inflection at (1, f(1))
Answer:
The value of c is [tex]c = \frac{1}{3}[/tex]
Step-by-step explanation:
Point of inflection:
A function f(x) has a point of inflection at the values of x for which:
[tex]f^{\prime}(x) = 0[/tex]
Has a point of inflection at (1, f(1))
This means that [tex]f^{\prime}(1) = 0[/tex]
f(x) = cx^2 + 1/x^2
This means that, applying the derivative of a power rule:
[tex]f^{\prime}(x) = 2cx - \frac{2}{x^3}[/tex]
Since [tex]f^{\prime}(1) = 0[/tex]
[tex]2c - \frac{2}{3} = 0[/tex]
[tex]2c = \frac{2}{3}[/tex]
[tex]c = \frac{2}{2*3} = \frac{1}{3}[/tex]
The value of c is [tex]c = \frac{1}{3}[/tex]

to x = 4?
o
A. 16
B. 8
C. 18
O D. 12
Answer:
D. 12
Step-by-step explanation:
The average rate of change between the interval, x = 2 to x = 4, in the given function is: D. 12.
What is the Average Rate of Change Within an Interval?Average rate of change = change in y / change in x = (y2 - y1)/(x2 - x1).
Given the interval of the function, as x = 2 to x = 4, we have:
(x1, y1) = (2, 8)
(x2, y2) = (4, 32)
Average rate of change = change in y / change in x = (32 - 8)/(4 - 2) = 24/2
Average rate of change = 12

The Medical College Admissions Test (MCAT) is a standardized, multiple-choice examination created to help medical school admissions officers assess a medical school applicants problem solving and critical thinking skills, as well as knowledge of natural, behavioral, and social science concepts and principles prerequisite to the study of medicine. The lowest raw total score on the test is 472 while the highest raw total score is 528. For the current version of the MCAT, the population mean is 501.1 and the population standard deviation is 10.6 points.
1. Alison scored 515 on the MCAT. What is the percentage of test takers who scored less than Alison (what is the percentile rank associated with a raw score of 515)?
2. Kamal scored higher than 82% of the test takers. What is Kamal's percentile—what is Kamal's score on the MCAT?
3. What percentage of test takers scored between 505 and 510 on the MCAT?
Answer:
1. 90.49% of test takers scored less than Alison.
2.
Kamal scored in the 82th percentile.
Kamal's score was of 510.8.
3. 15.52% of test takers scored between 505 and 510 on the MCAT.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
For the current version of the MCAT, the population mean is 501.1 and the population standard deviation is 10.6 points.
This means that [tex]\mu = 501.1, \sigma = 10.6[/tex]
1. Alison scored 515 on the MCAT. What is the percentage of test takers who scored less than Alison (what is the percentile rank associated with a raw score of 515)?
The proportion is the pvalue of Z when X = 515. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{515 - 501.1}{10.6}[/tex]
[tex]Z = 1.31[/tex]
[tex]Z = 1.31[/tex] has a pvalue of 0.9049
0.9049*100% = 90.49%
90.49% of test takers scored less than Alison.
2. Kamal scored higher than 82% of the test takers. What is Kamal's percentile—what is Kamal's score on the MCAT?
Kamal scored in the 82th percentile.
His score is the value of Z when Z has a pvalue of 0.82. So X when Z = 0.915.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.915 = \frac{X - 501.1}{10.6}[/tex]
[tex]X - 501.1 = 0.915*10.6[/tex]
[tex]X = 510.8[/tex]
Kamal's score was of 510.8.
3. What percentage of test takers scored between 505 and 510 on the MCAT?
The proportion is the pvalue of Z when X = 510 subtracted by the pvalue of Z when X = 505. So
X = 510
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{510 - 501.1}{10.6}[/tex]
[tex]Z = 0.84[/tex]
[tex]Z = 0.84[/tex] has a pvalue of 0.7995
X = 505
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{505 - 501.1}{10.6}[/tex]
[tex]Z = 0.37[/tex]
[tex]Z = 0.37[/tex] has a pvalue of 0.6443
0.7995 - 0.6443 = 0.1552
0.1552*100% = 15.52%
15.52% of test takers scored between 505 and 510 on the MCAT.
