the sum of a number and six is less than the sum of three times the number and ten. Write an inequality
Answers
The correct answer or an inequality is x+6 < 3x + 10.
What is an inequality equation in mathematics?
An inequality in mathematics is said to be a relation that compares two numbers or other mathematical expressions in an unequal way. The most frequent application is said to size-compare two numbers on a number line.
Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains.
However, these factors will shift the direction of inequality:
1. By using a negative number to multiply or divide both sides
2. Reversing the left and right sides.
Let the number be x. It is given in the question that the sum of a number and six is less than the sum of three times the number and ten.
According to the question,
x+6 < 3x + 10
Hence, the correct answer is x+6 < 3x + 10.

Today, full-time college students report spending a mean of 27 hours per week on academic activities, both inside and outside the classroom. Assume the standard deviation of time spent on academic activities is 4 hours. If you select a random sample of 16 full-time college students, a. what is the probability that the mean time spent on academic activities is at least 26 hours per week? b. there is an 85% chance that the sample mean is less than how many hours per week? c. If you select a random sample of 64 full-time college students, there is an 85% chance that the sample mean is less than how many hours per week?
Answers
(a) The probability that the mean time spent on academic activities is at least 26 hours per week is 0.317.
(b) If 64 random full-time college students are selected, there is an 85% chance that the sample mean is less than 27.52 hours.
Full-time college students report spending a mean of 27 hours per week on academic activities, both inside and outside the classroom. Assume the standard deviation of time spent on academic activities is 4 hours.
In a set with mean μ, the standard deviation σ and the z score of measure X is given by:
Z = ( X - μ )/σ
The theorem of central limits: According to this, the sample mean with size n can be roughly compared to a normal distribution with mean and standard deviation for a normally distributed random variable, X, with mean and standard deviation:
s = σ/√n
(a) In this we have to find the probability that the mean time spent on academic activities is at least 26 hours per week,
s = σ/√n
s = 4/√16
s = 4/4 = 1
Therefore, 1 is subtracted from the p-value of Z when X = 28.
So,
Z = ( X - μ )/σ
Z = ( 28 - 27)/1 = 1
For Z = 1 the p-value is 0.317.
(b) If 64 full-time college students are selected randomly.
85% chance that the sample mean is less.
s = σ/√n = 4/√(64) = 4/8 = 1/2 = 0.5
When the p-value is 0.85, Z = 1.04
Z = ( X - μ )/σ
1.04 = ( X - 27)/0.5
X - 27 = 0.52
X = 27.52

The perimeter of the figure is sum of the side of the figure. If figure is dilated by factor of 3, means that each side of the figure is dilated by 3.
The addition of dilated side to obtain the perimeter results in 3 times the original perimeter.

Looking at the graph, it is:

Thus,
[tex]f(4)=2[/tex](a)(ii)To evaluate f(-3), we take the functional value at x = -3.
Looking at the graph, it is:
At x = -3, y = -5 [counting units]

[tex]x=2,x=-5[/tex](c)The function f(x) is increasing where the slope of the graph is positive.
Looking at the graph, the increasing part is from x = -3 to x = 5.
That is
- 3 < x < 5
The correct choice is (2).
(d)The relative minimum is the lowest point of the graph shown and the relative maximum is the highest point of the graph.
Looking at the graph,
The lowest point occurs at --- (-3, -5)
The highest point occurs at --- (-7, 5)
So,
Relative Maximum: (-7, 5)
Relative Minimum: (-3, -5)
(e)We want the interval in which f(x) < 0.
This means where the function is less than zero, or below the x-axis.
Looking at the graph,
from x = -5 to x = 2, the graph of f(x) is below the x-axis.

where (a,b) is the center of the circle and r is the radius of the circle

Answers
The constant of proportionality is 0.0133
How to determine the constant of proportionality?From the question, the given parameters are
Relationship: p = 2 over 150 q
Rewrite the expression properly
So, we have
p = 2/150q
The above parameters can be represented as the following points
(p, q) = (150, 2)
The constant of proportionality of the points is then calculated as
k = q/p
Substitute the known values in the above equation
So, we have the following equation
k = 2/150
Evaluate the quotient in the above expression
So, we have
k = 0.0133

How to find third angle :The sum of a triangle's interior angles equals 180o. When the other two angles of a triangle are known, subtract the number of degrees in the other two angles from 180 degrees to find the third angle. A triangle has three parallel straight sides. The lengths of the sides can vary, but the largest side's length cannot be equal to or greater than the sum of the other two sides. Furthermore, a triangle has three interior angles, the sum of which is always 180 degrees.
We have a Right angle triangle and a value of an angle 18.4.
That is one angle is 18.4° and other is 90°.
To find third angle just add two angles and subtract that with 180.
Add two angle we have 18.4 + 90 = 108.4Subtract 108.4 with 180 = 180 -108.4 = 71.6°The third angle is 71.6°
