The water diet requires one to drink two cups of water every half hour from when one gets up until one goes to bed, but otherwise allows one to eat whatever one likes. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are
Person 1 2 3 4
Weight before the diet 180 125 240 150
Weight after six weeks 170 130 215 152
For the population of all adults, assume that the weight loss after six weeks on the diet (weight before beginning the diet minus weight after six weeks on the diet) is normally distributed with mean (µ). When testing the claim that the diet leads to weight loss after six weeks for all adults given that α=0.05, do you reject or fail to reject the Null Hypothesis, why or why not?

Answers
let one angle be X
so, other angle be 5x-12
ATQ
X+5x-12=180
6x=180-12
6x=168
X=168/6
hence X=28
now,one angle=28
other angle is 5×28-12
= 140-12.

an experiment compares the heights of two plants over time. a plant was 2 cm tall at the beginning of the experiment and grew 0.5 centimeters each day. the function f(t)=0.5t+2 represents the height of the plant in centimeters after t days.
The graph shows the height of the second plant, g(t) in centimeters, as a function of time t in days.
Part 1: which plant, f or g, was growing faster?
Part 2: Which plant, f or g, was taller to begin with?
Part 3: Which plant, f or g, was taller after 8 days?
Answers
Answer:
Part 1: plant f
Part 2: plant g
Part 3: plant g
Step-by-step explanation:
✔️First plant:
Function: f(t) = 0.5t + 2
where,
f(t) = height of plant
t = number of days
m = slope/rate of change = 0.5 cm/day
b = y-intercept/initial height = 2 cm
✔️Second Plant: using two points on the graph, (0, 5) and (16, 9), let's find b and m for the function of the second plant.
Slope/rate of change (m) = ∆y/∆x = (9 - 5)/(16 - 0) = 4/16 = 0.25
m = 0.25 cm/day
The y-intercept or initial height is the y-coordinate of the point where the line intercepts the y-axis = 5
b = 5 cm
Towbrute the equation of the function, substitute m = 0.25 and b = 5 into g(t) = mt + b
Thus:
g(t) = 0.25t + 5
Knowing these, let's answer the problem given:
Part 1: plant f was growing faster because it has a greater rate of change/slope (m) of 0.5 cm/day
Part 2: plant g was taller because it has a greater initial value/y-intercept (b) which is 5 cm
Part 3: To find out which plant was taller after 8 days, substitute t = 8 into the equation of each function:
Plant f: f(t) = 0.5t + 2
f(8) = 0.5*8 + 2 = 4 + 2
f(8) = 6 cm
Plant g: f(t) = 0.25t + 5
g(8) = 0.25*8 + 5 = 2 + 5
g(8) = 7 cm
Thus, plant g was taller after 8 days having 7 cm

Four members of a relay team evenly split the distance of a race. Each person ran more than 100 meters. Which inequality can be used to represent d, the total distance the group ran?
4 d greater-than 100
4 d less-than 100
StartFraction d Over 4 EndFraction greater-than 100
StartFraction d Over 4 less-than 100
Answers
Answer:
The answer would be C.
Step-by-step explanation:
Since each person ran more than 100 meters, the answer would be greater than 100.
d is the total distance the group ran, not the individual distance, so it couldn't be 4d because that would mean it would be 4 times d.
The answer would be d divided by 4. d/4. That is because the total distance divided by 4 would be the individual distance.
Answer:
it is c

A flag pole casts a 5 foot shadow while a nearby sign post casts a l 1/4 foot shadow. Find the height of the flagpole if the sign post is 4 feet high.
Answers
Answer:
16 ft
Step-by-step explanation:
if the signpost is 4 ft and the shadow is 1.25 feet, the ratio of the shadow to post is 1.25:4 or 5/16
If the flagpole makes a 5 ft shadow, the equation for the height is 5/(5/16)
5/(5/16) = 5/0.3125 = 16

What do we mean by the solution set to a system of equations?
The solution set to a system of equations is the set of all points that satisfies every equation in the given system.
How do we solve the given question?We are asked to find the apparent solution set of the system of equations graphed on the grid.
The solution set will be the set of common points on the graph as they satisfy both the equations in the given system.
The common points are (1, -4) and (4, -1), as the equations pass through these points simultaneously.
