Answer:
the last option -5 ≤ x ≤ 3
Step-by-step explanation:
Because the line there means what x can be so x has to be grater than -5 but less then 3 because the line does not go over 3.
Answer:
- 5 ≤ x ≤ 3.
Step-by-step explanation:
The range of the required values is in the bold line.
The solid circles at the end of the bold line mean the values at these points are included in the inequality.
So it is:- x is greater than or equal to -5 and less than or equal to 3.
That is - 5 ≤ x ≤ 3.
The ratio of red apples to green apples on a farm is 3:1. If there are 180 red apples on the farm, how many green apples are there?
Answers
it’ll give you 60
so there are 60 green apples
Answer:
There is 60 green apples
Step-by-step explanation:
Since there is 1 green apple for every three red apples you could divide 180 by 3 which would equal 60 so there is 60 green apples.

A research group is comparing the learning outcomes of students who are taught a lesson using four different teaching techniques. There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researchers will randomly place the students into five equally sized treatment groups suitable for comparison, four of which will receive a different teaching technique and one of which will remain a control group.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, 3, 4, or 5. Assign the students to the treatment groups based on their label.
B Select a student, and identify the first digit reading from left to right on a random number table. If the first digit is 1 or 2, assign that student to the technique 1 group. Similarly, digits 3 or 4, 5 or 6, 7or 8, and 9 or 0 go with the technique 2, technique 3, technique 4, and control groups, respectively. Repeat this process for each student.
C Number each student from 1 to 75. Reading the numbers from left to right on a random number table, identify 60 unique numbers from 1 to 75. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
D Number each student from 00 to 74. Reading the numbers from left to right on a table of random numbers and looking at two digits at a time, identify 60 unique two-digit numbers from 00 to 74. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.

Opposite angles are congruent , so
9x - 5 = 103 (add 5 to both sides )
9x = 108 ( divide both sides by 9 )
x = 12
Consecutive angles are supplementary, sum to 180° then
7y + 103 = 180 ( subtract 103 from 180 )
7y = 77 ( divide both sides by 7 )
y = 11
------------------------------------------------------------------
(4)
Opposite sides are congruent, so
3x = 36 ( divide both sides by 3 )
x = 12
and
5y = 45 ( divide both sides by 5 )
y = 9

B. d(t) = [tex]\frac{t}{2.58}[/tex]; 3.49 ft
C. d(t) = t + 2.58; 11.58 ft
D. d(t) = 2.58t; 23.22 ft
Answers
Answer:
m= minutes
2.58*m
2.58*9=23.22
The snail will travel 23.32 feet in 9 minutes.
Step-by-step explanation:
Answer
As given
A snail travels at a rate of 2.58 feet per minute.
First write a rule to describe the function.
Let a is denoted the distance.
t is the time
Thus the function becomes
a = 2.58 × t
a = 2.58t
This denoted the distance travelled in t time.
Second how far will the snail travel in 9 minutes .
Put t = 9 mintues in the above equation.
a = 2.58 × 9
a = 23.22 feet
Therefore the distance travelled in 9 mintues are 23.22 feet .
Latisha owns two spas, one in Pine township and the other in Adams township. Each spa offers a 30-minute face, head, and neck massage to reduce muscle tension. However, therapists first ask each patient questions about their type of tension and stop about five minutes before the end of the 30 minutes to have time to prepare for the next patient. The number of minutes each therapist massages the patients at both spas is approximately Normally distributed, with the Pine spa having a mean of 22.6 minutes and a standard deviation of 1.7 minutes and the Adams spa having a mean of 21.0 minutes and a standard deviation of 2.8 minutes. If Latisha randomly selects 8 massage times from Pine and 9 from Adams, what is the probability that the mean time for Pine is longer than the mean time for Adams? 0.0748 0.7157 0.8264 0.9252

Applying the central angle theorem, the measure of arc CDE is: 172°.
What is the Central Angle Theorem?According to the central angle theorem, the measure of the central angle equals the measure of its intercepted arc.
Measure of arc CDE = 360 - m∠COE [central angle theorem]
Measure of arc CDE = 360 - (103+50+35)
Measure of arc CDE = 172°
