Answer:
1 2/3
Step-by-step explanation:
convert to improper fraction:
13/3 - 8/3
then solve:
13/3 - 8/3 = 5/3
convert back to a mixed number (unless your not supposed to, if that is the case then "5/3" is your answer):
"1 2/3" is "5/3" as a mixed number.
so your answer (as a mixed number) is:
"1 2/3"

Answer:
Step-by-step explanation:
The general equation of the circle
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Center = c = (h,k) , radius = r
if C = (0,0) , r = 3
The equation will be :
(x-0)^2+(y-0)^2=3^2

In the figure shown what is the value of x?
Answer:
23 is the right answer hope it's helps you
The value of x from the given congruent triangles is 23 units.
In the figure ΔABC and ΔDEF are given.
What is the congruence theorem?Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.
Consider, ΔABC and ΔDEF, we have
AB=DE (Given)
∠BAC=∠EDF (Given)
AC=DF (Given)
So, ΔABC ≅ ΔDEF
We know that, by CPCT
BC=FE
⇒ x-4=19
⇒ x=23 units
Therefore, the value of x from the given congruent triangles is 23 units.

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.
write the equation of the line that is parallel to y=4x-1 and passes through the point (4.9)
9514 1404 393
Answer:
y = 4x -7
Step-by-step explanation:
Rearranging the slope-intercept for equation, we can find the intercept:
y = mx +b
y -mx = b . . . . . subtract mx
We know the slope of the parallel line is the same as that of the given line (m=4), so we only need to find 'b'.
b = 9 -4(4) = -7
The desired equation is ...
y = mx +b
y = 4x -7

Answer:
a: Neither; b: Complementary
Step-by-step explanation:
Complementary= 90 degrees
Supplementary= 180 degrees
For letter a. the answer is neither because 85 +90= 175 degrees, not 90 or 180 degrees.
For letter b. the answer is complementary because 75 +15= 90 degrees.

9514 1404 393
Answer:
5
Step-by-step explanation:
A graph can be helpful. It shows possible integer coordinates of Z could be ...
(-1, 2) or (-5, 1)
These have distances 5 and 4√2 from Y, respectively. Of these, only the length YZ = 5 appears on your list of possible answers.
__
The hypotenuse of a right triangle is the diameter of the circumcircle. That is, the right angle vertex (Z) appears on a circle whose center is the midpoint of the hypotenuse. Here, that circle center is C = (-4-1, 2-3)/2 = (-5/2, -1/2). The given point Y differs from this by C - Y = (-5/2 -(-1), -1/2 -(-3)) = (-3/2, 5/2). So, a point with integer coordinates will be 2×(5/2) = 5 units above point Y, which puts it in the 2nd quadrant.
__
Adding any of the 8 combinations (±3/2, ±5/2) or (±5/2, ±3/2) to the circle center coordinates will result in integer coordinates for the right angle vertex. Of these, only the ones listed above are in the second quadrant. A couple are on the y-axis, and two of the possibilities are X and Y. The other two are in the third quadrant.

Do you expect the difference between the 25th percentile and the median (50th percentile) to be Group of answer choices Larger than the difference between median and 75th percentile. We need to see the actual data to answer this question Smaller than the difference between median and 75th percentile. Equal to the difference between median and 75th percentile.
Answer:
Equal to the difference between median and 75th percentile.
Step-by-step explanation:
xth percentile:
If a measure is said to be in the xth percentile, it means that x% of the measures are smaller than it, and (100-x)% are larger.
Distance between percentiles:
If the difference between two percentiles is the same, the difference between the measures should also be the same.
Median:
The 50th percentile is called median.
In this question:
75th percentile - 50th percentile = 25
50th percentile - 25th percentile = 25
The differences should be equal.

Step-by-step explanation:
The amount of oil and natural gas a given region produces is not always proportionate to the size of its proven reserves. For example, the Middle East contains approximately 50 percent of the world’s proven reserves but accounts for only about 30 percent of global oil production (though this figure is still higher than in any other region). The United States, by contrast, lays claim to less than 2 percent of the world’s proven reserves but produces roughly 16 percent of the world’s oil.

Multiplication Property of EqualityDivision Property of EqualityAddition Property of EqualitySubtraction Property of EqualityAlgebra I
Terms/CoefficientsStep-by-step explanation:
Step 1: Define
5(2x - 8) + 15 = -15
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 15 on both sides: 5(2x - 8) = -30[Division Property of Equality] Divide 5 on both sides: 2x - 8 = -6[Addition Property of Equality] Add 8 on both sides: 2x = 2[Division Property of Equality] Divide 2 on both sides: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(2(1) - 8) + 15 = -15(Parenthesis) Multiply: 5(2 - 8) + 15 = -15(Parenthesis) Subtract: 5(-6) + 15 = -15Multiply: -30 + 15 = -15Add: -15 = -15Here we see that -15 does indeed equal -15.
∴ x = 1 is the solution to the equation.
Answer: x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2x−8)+15=−15
Step 1: Simplify both sides of the equation.
5(2x−8)+15=−15
(5)(2x)+(5)(−8)+15=−15(Distribute)
10x+−40+15=−15
(10x)+(−40+15)=−15(Combine Like Terms)
10x+−25=−15
10x−25=−15
Step 2: Add 25 to both sides.
10x−25+25=−15+25
10x=10
Step 3: Divide both sides by 10.
10x/10=10/10
