Step-by-step explanation:
A new version of the Medical College Admissions Test (MCAT) was introduced in spring 2015 and is intended to shift the focus from what applicants know to how well they can use what they know. One result of the change is that the scale on which the exam is graded was modified, with the total score of the four sections on the test ranging from 472 to 528. In spring 2015, the mean score was 500.0 with a standard deviation of 10.6.
Required:
What are the median and the first and third quartiles of the MCAT scores?
Answer:
The median of the MCAT scores was of 500.
The first quartile of MCAT scores was of 492.845.
The third quartile of MCAT scores was of 507.155.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
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.
The mean score was 500.0 with a standard deviation of 10.6.
This means that [tex]\mu = 500, \sigma = 10.6[/tex]
Median:
In a normal distribution, the median is the same as the mean, so the median of the MCAT scores was of 500.
First quartile:
This is the 100*(1/4) = 25th percentile, which is X when Z has a pvalue of 0.25. So X when Z = -0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.675 = \frac{X - 500}{10.6}[/tex]
[tex]X - 500 = -0.675*10.6[/tex]
[tex]X = 492.845[/tex]
The first quartile of MCAT scores was of 492.845.
Third quartile:
This is the 100*(3/4) = 75th percentile, which is X when Z has a pvalue of 0.75. So X when Z = 0.675.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.675 = \frac{X - 500}{10.6}[/tex]
[tex]X - 500 = 0.675*10.6[/tex]
[tex]X = 507.155[/tex]
The third quartile of MCAT scores was of 507.155.

Which table and graph represent the equation y = 3X?
The table and graph that represents the equation y = 3x are:
Table A
Graph B.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
y = 3x
This means,
For x = 0, 1, 2, 3,
y = 0, 3, 6, 9
Now,
The coordinates on the graph of the equation y = 3x will have:
(0, 0), (1, 3), (2, 6), and (3, 9)
We see that,
Graph A has the coordinates:
(0,3).
This is not possible.
And,
Table B has y = 1 when x = 3.
This is not possible.
Thus,
The table and graph that represents the equation y = 3x are table A and graph B.

What is the b term of the product of (x – 4) and (2x + 3) ?
Answer:
the "b" term is the term "-5 x" in the final quadratic expression
Step-by-step explanation:
Normally the "b" is the "linear term" in a quadratic equation.
So, perform the product of binomials and combine like terms to identify the final "b" term of the quadratic expression you get:
[tex](x-4)*(2x+3)=2x^2 +3x-8x-12=2x^2-5x-12[/tex]
Therefore the "b" term is the term "-5 x" in the final quadratic expression.

Find the 4th term in the sequence
with the following definition:
a1 = 2
an = (an-1)2
The sum of the first four terms of the given sequence which is aₙ = (aₙ ₋ ₁)² is gotten as; 278
How to solve arithmetic sequence?We are given the arithmetic sequence as;
a₁ = 2
aₙ = (aₙ ₋ ₁)²
We already have the first term. Thus;
Second Term;
a₂ = (a₂ ₋ ₁)²
a₂ = 2² = 4
Third Term;
a₃ = 4²
a₃ = 16
Fourth Term;
a₄ = 16²
a₄ = 256
Thus;
Sum of first four terms is;
S₄ = 2 + 4 + 16 + 256
S₄ = 278

0.4y − 0.2y + 10 = 11.8
Answer:
0.2y+10
Step-by-step explanation:
Answer:
We have this equation:
0.4y - 0.2y + 10 = 11.8
You can simplify
0.2y + 10 = 11.8
Then, you can substract 10 in both sides:
0.2y = 11.8 - 10
0.2y = 1.8
You can now divide right and left side by 0.2 and get y:
0.2y/0.2 = 1.8/0.2
y = 14
