The data representation where the median is the better measure of the center is the third data representation.
How to illustrate the data?
From the information, the last bar graph is skewed to the right, since the values of its fourth and fifth bars are way smaller than the values of its first, second, and third graphs.
The drastically smaller values pull down the mean of the last bar graph. Comparatively, bar graphs one and two have symmetrical distributions of numbers on both sides of the central bar and this implies that their mean is balanced out on both sides and that neither of them is significantly skewed left or right.

Consider the line y=-7x+8. -- Find the equation of the line that is perpendicular to this line and passes through the point (8. -3). Find the equation of the line that is parallel to this line and passes through the point (8. –3).
Equation of perpendicular line:
Equation of parallel line:
Answer:
Step-by-step explanation:
Perpendicular formula
m1 * m2 = - 1
Givens
m1 = - 7
m2 = ??
Solution
-7 * m2 = -1
m2 = 1/7
y = 1/7 x + b
x = 8
y = -3 Substitute these values into y = 1/7 x + b
-3 = (1/7)*8 + b
-3 = 8/7 + b Subtract 8/7 from both sides
-3 - 8/7 = b
-4 1/7 = b
Answer (perpendicular line) y = (1/7) x - 4 1/7 or
Answer (perpendicular line) y = (1/7) x - 4.14
Parallel line
Nothing changes except you have a different y intercept.
y = -7x + b
x = 8
y = -3 Substitute these values into y = -7x + b
-3 = -7*8 + b
-3 = - 56 + b
-3 + 56 = b
b = 53

9=(1/27)^a+3 find a
-11/3
-7/3
7/3
11/3
Step-by-step explanation:
I think you made some mistakes in the problem definition.
I guess you mean
9 = (1/27)^(a+3)
let's think about how to create 9 out of 1/27 just by using exponents.
we note that 27 is 3³. and therefore the cubic root of 27 is 3.
so,
(1/27)^(1/3) = 1/3
because the exponent 1/3 means "cubic root". an exponent 1/2 means square root. and so on.
making the exponent negative means 1/...
so,
(1/27)^(-1/3) = 3
and now, with what exponent operation can we turn 3 into 9 ?
by squaring it.
so,
((1/27)^(-1/3))² = 9
putting an exponent on an exponent means to multiply the exponents during simplification.
therefore,
((1/27)^(-1/3))² = (1/27)^(-2/3) = 9
that means
a + 3 = -2/3
a = -2/3 - 3 = -2/3 - 9/3 = -11/3
so, the first answer option is correct.

Three sides of a triangle measure 15, 19, and 26 respectively. What is
the measure of the largest angle? Round to the nearest whole degree.
Applying the law of cosine, the largest angle in the given triangle, to the nearest whole degree, is: 99°.
What is the Law of Cosine?Law of cosine is, c² = a² + b² - 2ab(cosC)
Let,
a = 15b = 19c = 26Largest angle = CPlug in the values into the formula for the law of cosine:
26² = 15² + 19² - 2(15)(19)(cosC)
676 = 586 - 570(cosC)
676 - 586 = -570(cosC)
90 = -570(cosC)
90/-570 = cos C
-0.1579 = cos C
C = cos^(-1)(-0.1579)
C = 99°

The requried, factored form of the given expression is (x - 1)(x - 3)(x + 2).
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
To factor the polynomial f(x) = x³ – 2x² – 5x + 6 completely, we can use a combination of the rational root theorem and synthetic division.
We can use synthetic division to test each possible root and see if it is a factor of the polynomial. Starting with x = 2, we have:
2 | 1 -2 -5 6
| 2 0 -10
|_____________
1 0 -5 -4
Since the remainder is not zero, x = 2 is not a factor of the polynomial. Continuing with the other possible roots, we find that x = 1 and x = 3 are roots, but x = -1, x = -2, x = -3, and x = -6 are not roots.
Therefore, we can factor the polynomial as follows:
f(x) = x² – 2x² – 5x + 6
= (x - 1)(x - 3)(x + 2)
So the completely factored form of f(x) is f(x) = (x - 1)(x - 3)(x + 2).

A medical center conducted a study to investigate cholesterol levels in people who have had heart
attacks. A random sample of 16 people was obtained from the names of all patients of the medical
center who had a heart attack in the previous year. Of the people in the sample, the mean cholesterol level was 264.70 milligrams per deciliter (mg/dL) with standard deviation . Assuming all conditions for inference were met, which of the following is a 90 percent confidence interval for the mean cholesterol level, in, of all patients of the medical center who had a
heart attack in the previous year?
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 90% confidence interval is (246.6, 282.8).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 16 - 1 = 15 df, is t = 1.7531.
Researching the problem on the internet, the standard deviation was of 42.1 mg/dL, hence the parameters are as follows:
[tex]\overline{x} = 264.7, s = 41.2, n = 16[/tex]
Thus, the bounds of the interval are given by:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 264.7 - 1.7531\frac{41.2}{\sqrt{16}} = 246.6[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 264.7 + 1.7531\frac{41.2}{\sqrt{16}} = 282.8[/tex]
The 90% confidence interval is (246.6, 282.8).
