Answer:
x≥-4
Step-by-step explanation:
-5(x + 1) ≤ 15
-5x-5≤ 15
-5x≤20 5 was added on both sides
x[tex]\geq[/tex]-4 divided by -5 on both sides and since we divided by a negative
number, the inequality sign was flipped
Answer:
Step-by-step explanation:
5(x + 1) ≤ 15
In order to solve this linear inequality, we need to group all the variable terms on one side, and all the constant terms on the other side of the inequality.
In our example,
- term 5, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the inequality to the other.
A research analyst for a car rental agency found that the probability distribution function for the age of the rental car (in years) is a straight line. The line decreases from the point (0, h) to the point (10, 0). None of the rental cars are older than 10 years. Enter your answers as decimals. 7(a). What is the height for the line when the age of the car is zero?
Answer:
10 years
Step-by-step explanation:
Given
Decline from (0,h) to (10,0)
See attachment for graph
Required
Determine the age when height = 0
The function of the graph is represented as: (age, height)
So, we need to read from the graph the corresponding value of age (on the x-axis) when height = 0 (i.e. the y-axis)
From the attached graph;
[tex]age = 10[/tex] when [tex]height = 0[/tex]
Hence, the age of the car is 10 years

is 4x-2y=5 and -2x+y= 1 no solution? if not what is it?
Answer: no solution
Step-by-step explanation:
here are the equations in y=mx+b form:
y=2x+1
y=2x+ -5/2
as you can see they have the same slope with different y-intercepts, this mean there are parallel AKA no solution

Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.
(a) Identify the population of interest and the sample in this study.
(b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.
Step-by-step explanation:
A) Population of interest = children between the ages of 5 and 15
Sample = 160 children between the ages of 5 and 15.
B) Sample size is 160 which is above 30.
Thus, we can say;
Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.
Yes, the findings can be used to establish causal relationship because the study is just an experiment.

convert 0.5t5kg5hg to kilogram
Answer:
505.5kg
Step-by-step explanation:
To convert 0.5t5kg5hg to kilogram, first we need to convert 0.5t and 0.5hg to kg as shown;
1t = 1000kg
0.5t = 0.5 *1000
0.5t = 500kg
Similarly
1hg = 0.1kg
5hg = 5 * 0.1
5hg = 0.5kg
Adding up;
0.5t5kg5hg = 500kg+5kg+0.5kg
0.5t5kg5hg = 505.5kg
Hence the conversion to kg is 505.5kg

The area of a triangle is 20 square feet.
What are the height and base of the
triangle?
On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, negative 2), and point K is at (negative 2, negative 3).
HIJK is a parallelogram because the midpoint of both diagonals is __________, which means the diagonals bisect each other.
(1,−1)
(1,1)
(1,0)
(0,1)
Answer:
(1,0)
Step-by-step explanation:
Given
[tex]H = (-2,2)[/tex]
[tex]I = (4,3)[/tex]
[tex]J = (4,-2)[/tex]
[tex]K = (-2,-3)[/tex]
Required
The midpoint of the diagonals
Midpoint is calculated as:
[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
For H and J, the midpoint is:
[tex]M = (\frac{-2+4}{2},\frac{2-2}{2})[/tex]
[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]
[tex]M = (1,0)[/tex]
For I and K, the midpoint is:
[tex]M = (\frac{4 - 2}{2},\frac{3-3}{2})[/tex]
[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]
[tex]M = (1,0)[/tex]
The midpoint of both diagonal is: (1,0)

The Robotics Manufacturing Company operates an equipment repair business where emergency jobs arrive randomly at the rate of three jobs per 8-hour day. The company's repair facility is a single-server system operated by a repair technician. The service time varies, with a mean repair time of 2 hours and a standard deviation of 1.5 hours. The company's cost of the repair operation is $28 per hour. In the economic analysis of the waiting line system, Robotics uses $35 per hour cost for customers waiting during the repair process. What are the arrival rate and service rate in jobs per hour
Answer:
The correct answer is:
[tex]\lambda=0.375 \ jobs \ per \ hour[/tex][tex]\mu=0.5 \ jobs \ per \ hour[/tex]Step-by-step explanation:
The given values are:
Service time varies,
Repair time = 2 hours
Standard deviation = 1.5 hours
Robotics uses per hour cost,
= $35
Company's cost per hour,
= $28
(a)
⇒ Arrival rate = Jobs per hours
then,
= [tex]\frac{8 \ hours}{3 \ jobs}[/tex]
= [tex]2.666 \ hours \ per \ job[/tex]
The jobs per hour will be:
⇒ [tex]\lambda=\frac{1}{2.666}[/tex]
[tex]=0.375[/tex]
(b)
⇒ Service rate = jobs per hour
then,
μ = [tex]\frac{1 \ repair \ job}{2 \ hours}[/tex]
= [tex]0.5 \ jobs[/tex]

You are asked to draw a triangle with side lengths of 10 inches and 13 inches. What is the longest whole number length that your third side can be?
Answer:
22
Step-by-step explanation:
10 plus 13 equals 23, so if it is more than that than the lines wont be able to connect. if it is 23 exactly, the triangle will be a stright line, not a triangle, so it is 22.
Answer:
22
Step-by-step explanation:
triangle inequality theorem:
10 + 13 > x
x < 23
10 + x > 13
x > 3
third side: 3 < x < 23

Evaluate 2.5(8.6/2)-1.8
Step-by-step explanation:
Given the expression:
[tex]2.5( \frac{8.6}{2} ) - 1.8[/tex]
Follow BODMAS rule.
always evaluate brackets first, followed by multiply or division then addition or subtraction from LEFT to RIGHT.
[tex]2.5( \frac{8.6}{2} ) - 1.8 \\ = 2.5(4.3) - 1.8 \\ = 10.75 - 1.8 \\ = 8.95[/tex]
hi guys what is and can u please do the method 4050 divided by 100
Answer:
40.5
Step-by-step explanation:
what i do is I divided first by 10. because 100 is 10x10.
so 4050 divided by 10 is 405.
405 divided by 10 is 40.5
4050 divided by 100 = 40.5
If the length of the radius and the height of a right circular cylinder are both tripled to form a larger cylinder, what is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? (Note: The two cylinders are said to be "similar.")
Answer:
The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27:1
Step By Step Explanation:
Volume of the smaller cylinder(V1)=π(r^2)h
Volume of the larger cylinder(V2)=π(r^2)h
=π(3r)^2*3h
=π*9(r^2)*3h
=27π(r^2)h
The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27π(r^2)h/π(r^2)h i.e. 27:1

Answer:
P₂ and x are both supplementary to N₁Q₁R = 90° -xΔSMP ≅ ΔSMR ∴ PS ≅ SRStep-by-step explanation:
1. Angles P₂ and N₁ are opposite angles of inscribed quadrilateral PMNQ, so are supplementary. Angles N₁ and N₂ form a linear pair, so are supplementary. Angles supplementary to the same angle (N₁) are congruent, hence P₂ = x ≅ N₂
__
2. ΔPMQ is isosceles, so angle Q₁ is also congruent to x.
__
3. In ΔPMQ, the sum of angles is 180°, so ...
M₁ +2x = 180°
Dividing by 2 gives ...
M₁/2 +x = 90°
Angle M₁ subtends arc PQ of circle M. Angle R inscribed in circle M subtends the same arc, so ...
R = (M₁/2)
R = 90° -x
__
4. From the above, we know that angles N₂ and R are complementary (total 90°), so angle S₂ = 90°. Segment MS will only intersect chord PR at right angles at the midpoint of that chord.
Hence S is the midpoint of PR and PS = SR.
