How do you solve simple linear equations
Answers
Answer:
See Explanation
Step-by-step explanation:
I think you mean how do you find linear equations. It is actually very simple when you memorize the formula. Linear equations are in the form of y = mx + b. m is the slope. b is the y-intercept.
ex. given: slope = 5, y-intercept = -3: our equation is y = 5x - 3
Slope is rise/run
y-intercept is (0,y) or you substitute.

Answer:
1) m = 5
2) c = 12.5
Step-by-step explanation:
1) T = 2m + 30
T = 40
substitute for T
2m + 30 = 40
2m = 10
m = 5

The numbers of points scored in each basketball game are 49, 36, 61, 64, 39, 41, 43, and 39.
In what percent of the games were at least 55 points scored?
Answers
Answer:
In 25% of the games at least 55 points were scored.
Step-by-step explanation:
Percentage:
Number of desired outcomes multiplied by 100 and divided by the number of total outcomes.
In this question:
8 total games
In 2 at least 55 were scores.
100*2/8 = 100/4 = 25%
In 25% of the games at least 55 points were scored.
a biology teacher wants to know which dissection his students liked best this semester, so he randomly selects eights students from each of his 5 classes to participate in a survey.
a. What is the sample in this situation?
b. What is the population?
THIS IS NOT MULTIPLE CHOICE
Answers
Answers:
a) The 40 students selected to participate in the survey (8*5 = 40).b) The population is the set of all students in his five classes combined.===========================================================
Explanation:
The teacher wants to know something about his students, so he's only focused on them and no one else. The teacher has 5 classes. Let's say each class has 40 students. That would mean 40*5 = 200 students total are taught by this bio teacher, and these 200 students make up the population. We're not considering any other student in this school since they are not in this teacher's class.
Once the population is well formed and well defined, the sample is drawn from the population. Specifically, the teacher is randomly selecting 8 people from each class. The teacher is using the stratified sample technique. Each class is a stratum, ie, a separate group. The plural of stratum is strata. Because there are 5 classes, and 8 people selected per class, this leads to an overall sample of 8*5 = 40 students. Those 40 students chosen randomly fairly represent the 200 students in the population. Therefore, this process is fairly unbiased.
Be sure not to mix stratified sampling with cluster sampling. Cluster sampling is not performed here because that would mean the teacher randomly selects say 2 classrooms (ie clusters) and samples everyone in each cluster selected. Instead, the teacher is only picking representatives from each class, as if those people were elected to office. As you can probably guess, cluster sampling can be expensive in terms of time and money, so if you need to apply a cluster sample, then it's best to make the clusters as small as possible but also make sure each cluster is reflective of the population.

If L(2, 7) is an endpoint of a line segment, and M(8, 3) is the midpoint, find the other endpoint of the segment.
Answers
Answer:
Step-by-step explanation:
From L to M,
change in x-coordinates = 8-2 = 6
change in y-coordinates = 3-7 = -4
Extrapolate from M(8,3) to find the other end of the segment:
8 + 6 = 14
3 - 4 = -1
Endpoint of segment: (14,-1)

Answer:
a) V = 4w²h
b) SA = 4w² +10wh
c) SA = 4w² +37.5/w
d) C = 40w² +225/w
Step-by-step explanation:
The relevant formulas are ...
V = LWH
base area = LW
lateral area = H(2(L+W))
__
a) The length is 4 times the width, so the volume is ...
V = (4w)(w)(h)
V = 4w²h
__
b) The total surface area is the sum of the base area and the lateral area:
SA = base area + lateral area
SA = (4w)(w) + 2h(4w +w)
SA = 4w² +10wh
__
c) The volume is 15 m³, so the height in meters in terms of the width in meters is ...
15 = 4w²h
h = 15/(4w²)
Then the surface area is ...
SA = 4w² +10w(15/(4w²))
SA = 4w² +37.5/w
__
d) The equation we have for surface area has one term for base area and a second term for lateral area. We can apply the cost factors to those terms to get the cost of materials:
C = 10(4w²) +6(37.5/w)
C = 40w² +225/w

in a mixture of one hundred liter of milk ans water 4:1 ratio of milk and water where is ratio of milk to water in the new mixture when 25% of the mixture is removed and the same amount of water is added?
Answers
Answer:
The milk to water ratio in the new mixture is 3:2.
Step-by-step explanation:
Given that in a mixture of one hundred liters of milk and water the ratio of milk and water was 4: 1, to determine what is the ratio of milk to water in the new mixture when 25% of the mixture is removed and the same amount of water is added, the following calculation must be performed:
(100/5) x 4 = 80
80 liters of milk
20 liters of water
80 x 0.75 = 60
20 x 0.75 = 15
15 + 25 = 40
60 + 40 = 100
Thus, the milk to water ratio in the new mixture is 3:2.
