The college student who is looking for a data plan for her cell phone found a third option,
which also offers a 2 gigabyte monthly allowance for data.
The monthly cost of this option can be represented by function C, defined by:
30x + 3 where x is the gigabytes of data used over the monthly allowance.
1. Find C (0.7) and explain what it means in this situation.
Answers
Answer:
Value of C(0.7) = 24 means that the cost of 0.7 gigabytes of data is $24
Step-by-step explanation:
We are told the monthly cost of the 2 gigabyte monthly allowance for data is;
C(x) = 30x + 3
where x is the gigabytes of data used over the monthly allowance
Now, we want to find C(0.7)
C(0.7) = 30(0.7) + 3
C(0.7) = 21 + 3
C(0.7) = 24
This value of C(0.7) = 24 means that the cost of 0.7 gigabytes is $24

8.F.2: Functions W and Z are both linear functions of x. Which statement comparing the functions is true? Select ALL that apply.
A. The slope of Function W is less than the slope of Function Z.
B. The slope of Function W is greater than the slope of Function Z.
C. The slope of Function W is equal to the slope of Function Z.
D. The y-intercept of Function W is less than the y-intercept of Function Z.
E. The y-intercept of Function W is equal to the y-intercept of Function Z.
F. The y-intercept of Function W is greater than the y-intercept of Function Z.
Answers
*the graph of Function W and table of values of Function Z are in the diagram attached below.
Answer:
B. The slope of Function W is greater than the slope of Function Z.
F. The y-intercept of Function W is greater than the y-intercept of Function Z.
Step-by-step explanation:
To determine which of the statements compare both functions correctly, let's find the slope (m) and the y-intercept (b) of each function given.
✍️Function W:
Slope of Function B, using two points on the line, (0, -1) and (2, 0):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-1)}{2 - 0} = \frac{1}{2} = 0.5 [/tex]
✅Slope = 0.5.
y-intercept is the point at which the line intercepts the y-axis. Therefore, the y-intercept, b = -1. The line cuts the y-axis at y = -1. At this point, x = 0.
✅y-intercept = -1.
✍️Function Z:
Slope of Function Z, using two pairs of values from the table of values for function Z, (0, -2) and (2, -1.5):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1.5 -(-2)}{2 - 0} = \frac{0.5}{2} = 0.25 [/tex]
✅Slope = 0.25.
y-intercept is the value of y when x = 0. It is at this point the line of the function of X intercepts the y-axis. From the table given, we can see that when x = 0, y = -2. Therefore:
✅y-intercept = -2.
Thus, the following statements that compares both functions are TRUE:
B. The slope of Function W is greater than the slope of Function Z.
✔️This is TRUE because 0.5 is greater than 0.25.
F. The y-intercept of Function W is greater than the y-intercept of Function Z.
✔️This is TRUE because -1 is greater than -2.

The no. Of adel beads to that of claire's beads was the ratio 7 :4 .When adel gave 68 beads to claire the ratio become 25 :41 . How many beads did claire did claire have finally
Answers
Answer:
37 beads
Step-by-step explanation:
Given that:
Adel : Claire = 7 : 4
Let Adel be = A; &
Let Claire be = C
A: C = 7 : 4
[tex]\dfrac{A}{C} =\dfrac{7}{4}[/tex]
7C = 4A
[tex]C = \dfrac{4A}{7}[/tex] --- (1)
When Adel gave 68 beads to claire, we have:
C + 68 = 25:41
[tex]\dfrac{A}{C+68}= \dfrac{25}{41}[/tex]
25(C + 68) = 41A
C + 68 = [tex]\dfrac{41}{25}A[/tex]
[tex]C = \dfrac{41}{25}A - 68[/tex] --- (2)
Equating (1) and (2) together;
[tex]\dfrac{4 * A}{7} = \dfrac{41 *A}{25} - 68[/tex]
[tex]\dfrac{4 * A}{7}-\dfrac{41 *A}{25} = - 68[/tex]
[tex]\dfrac{100A - 287 A}{175} =- 68[/tex]
[tex]\dfrac{-187A}{175} = -68[/tex]
- 187 A = 175 × (-68)
-187 A = - 11900
A = - 11900/ -187
A ≅ 64
From; [tex]C = \dfrac{4A}{7}[/tex]
[tex]C = \dfrac{4*64}{7}[/tex]
C = 36.57
C ≅ 37 beads

A man cycles to a village at 18km/hr and returns at 12km/hr. If he takes 6 tahrs
for the double journey, how far does he ride altogether?
Answers
Answer:
30km/hr
Step-by-step explanation:
18km/hr +12km/hr
The man rides 86.4 km distance.
What is speed?Speed tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance.
Speed is directly Proportional to Distance and inversely proportional to Time.
Speed = Distance/Time
Given,
Speed of man way to the village = 18km/hour
Speed of man when returns from the village = 12km/hour
Time for double journey = 6 hour
Let going time is x and returning time is y
x + y = 6 -------(a)
⇒ x = 6 - y
Distance for going = distance for returning
18x = 12y
Putting value of x in terms of y
18(6 - y) = 12y
108 - 18y = 12y
30y = 108
y = 108/30
y = 3.6 hours
Putting value of y in equation (a)
x + 3.6 = 6
x = 6 - 3.6
x = 2.4
Returning time = 3.6 hours
Returning distance = returning time × returning speed = 3.6 × 12
Returning distance = 43.2 km
Going distance = Returning distance = 43.2
Total ride distance = 43.2 + 43.2 = 86.4 km
Hence, 86.4 km is the distance of ride by the man.

Researchers wanted to assess the effect of low alcohol consumption on reaction time in seniors, believing that even low levels of alcohol consumption can impair the ability to walk, thereby increasing the likelihood of falling. They identified 13 healthy seniors who were not heavy consumers of alcohol. The experiment took place in late afternoon. Each subject was instructed to have a light lunch and to not drink any caffeinated drinks in the 4 hours prior to arriving at the lab. The seniors were instructed to walk on a treadmill on which an obstacle would appear randomly. The reaction time was measured by determining the time it took the senior to lift his or her foot upon the appearance of the obstacle. First, each senior walked the treadmill after consuming a drink consisting of water mixed with orange juice with the scent and taste of vodka. The senior was then asked to drink two additional drinks (40% vodka mixed with orange juice). The senior then walked on the treadmill again. The average response time increased by 19 milliseconds after the alcohol treatment. The researchers concluded that response times are significantly delayed even for low levels of alcohol consumption.
A) What type of experimental design is this?
B) What is the response variable in this experiment? Is it quantitative or qualitative?
C) What is the treatment?
D) What factors were controlled and set at a fixed level in this experiment?
E) Can you think of any factors that may affect reaction to alcohol that were not cont rolled?
F) Why do you think the researchers used a drink that had the scent and taste of vodka to serve as the treatment for a baseline measure?
G) What was the conclusion of the study? To whom does this conclusion apply?
Answers
Answer:
See explanation
Step-by-step explanation:
The matched pair experimental design was used here. In this type of design, the experimental units are paired up . Different individuals receive different treatments. A popular type of matched-pairs design is this; a response variable's effect on an experimental unit is measured before and after a treatment is applied.
Reaction time is the response variable here . It is quantitative because it can be counted or measured.
The treatment was water mixed with orange juice with the scent and taste of vodka and subsequently 40% vodka mixed with orange juice.
Food consumption and intake of caffeinated drinks were controlled and set at a fixed level in this experiment.
Age ,gender and weight may also affect the reaction of the seniors to alcohol .
This treatment served the purpose of a placebo thereby working as a control that helps us to establish a baseline treatment that can be used to compare with the results of other treatments .
The research conclusion is that response times are significantly delayed even for low levels of alcohol consumption in seniors .This conclusion can only be applied to healthy seniors that consume a low level of alcohol.
