For which of the following distributions is the mean most likely to be less than the median?
The distribution where the mean is most likely to be less than the median is the third histogram.
How to illustrate the information?It should be noted that when the histogram shows the day is left skewed, it means the mean is less than the median.
If it right skewed, the mean is greater than the median.
When they're equal, the data is symmetric.
In this case, based on the information, the distribution where the mean is most likely to be less than the median is the third histogram.

Por lo tanto el número es p/q = 8/64.
¿Qué es una fracción?Fracción es un número que se puede representar en forma de p/q, donde q no es igual a cero.
It is given that :
En su forma más simple, el número es 1/8
Sea el número p/q
p + q = 72 (dado)
p/q = 1/8
q = 8p
p+8p = 72

Consider the graph of the function : f(x)=logx
Which are features of function g if g(x)= 4log(x)+4
The features of the function g(x) = 4log(x) + 4 are
(b) range (-∞, ∞)(d) x-intercept (0.1, 0)(e) Vertical asymptote, x = 0How to determine the features of g(x)?The function is given as;
g(x) = 4log(x) + 4
The intercept
A logarithmic function has no y-intercept.
Set g(x) to 0, to determine the x-intercept
4log(x) + 4 = 0
Divide through by 4
log(x) + 1 = 0
This gives
log(x) = -1
Take the inverse of both sides
x = 10^-1
Evaluate
x = 0.1
The x-intercept is (0.1, 0)
The vertical asymptote
Recall that:
A logarithmic function has no y-intercept.
This is so because it is undefined at x = 0
So, the vertical asymptote is x = 0
The domain and the range
A logarithmic function cannot take a negative input or 0 input
So, the domain is x > 0
However, the range is all set of real numbers i.e (-∞, ∞)
Hence, the features of g(x) are (b), (d) and (e)

Which conditional and its converse form a true biconditional?
If x = 19, then 2x – 3 = 35.
If x = 3, then x2 = 9.
If x2 = 4, then x = 2.
If x > 0, then > 0.
The conditional and its converse that form a true biconditional is; Option A; If x = 19, then 2x – 3 = 35.
How to Interpret Biconditional Statements?
A) If x = 19, then 2x – 3 = 35.
Thus, 2(19) - 3 = 35. Thus, this is a true biconditional.
B) If x = 3, then x²= 9.
This is not a true biconditional because x could also be -3.
C) If x² = 4, then x = 2
This is not a true biconditional because x could also be -2.
D) If x > 0, then |x| > 0.
This is not a true biconditional because x could also be negative which less than zero.

I WILL MARK BRAINLIEST A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 20 child bikes and 6 adult bikes in a week.
Using a system of equations, it is found that since 20 child bikes and 6 adult bikes would require more testing than the allocated time, it is not possible to build this amount.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable c: number of child bikes.Variable a: number of adult bikes.Each child bike requires 4 hours to build, as do each adult bike. The company has 100 hours of testing, hence:
4c + 4a = 100.
c + a = 25.
With 20 child bikes and 6 adult bikes in a week, we have that c = 20, a = 26, hence:
c + a = 26
20 child bikes and 6 adult bikes would require more testing than the allocated time, it is not possible to build this amount.

On a coordinate plane, a quadrilateral has points E (negative 2, 0), D (0, 4), G (4, 2), and F (0, 0).
Which are true if figure DEFG is reflected across the x-axis? Check all that apply.
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from G' to the x-axis will equal 2 units.
The perpendicular distance from D' to the x-axis will equal 8 units.
The orientation will be preserved.
By applying the reflection rule across the x-axis to quadrilateral DEFG, we obtain the following true statements:

Step-by-step explanation:
This is a ratio problem. We can set up the proportion by letting x be the number of people who applied for admission:
[tex]\frac{4}{10}=\frac{640}{x}[/tex]
Since we know that 4 people get in for every 10 people that apply, we can set up an equation like the one above and solve for x by cross multiplying:

Step 2: Multiply 40 by 3
40 · 3 = 120
Answer: 3/5 of 200 = 120
Tip: When finding a fraction of a whole, divided the whole by the denominator, then multiply the quotient you got by dividing the whole by the denominator by the numerator
Example: 1/2 of 80
