Answer:
Step-by-step explanation:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
If your answer is a negative number, then this is a percentage increase

Find the slope.
Bonus: Write the equation of the line.
Answer:
1 so y=1+b
Step-by-step explanation:
9514 1404 393
Answer:
slope: -1equation: y = -x +3Step-by-step explanation:
The slope is the ratio of "rise" to "run". The "rise" is the vertical distance between two points; the "run" is the corresponding horizontal distance.
Here, we see point A is (0, 3) and point B is (1, 2). Then the "rise" is 2 -3 = -1, while the "run" is 1 - 0 = 1. The slope is the ratio ...
m = rise/run = -1/1 = -1
The slope of the line is -1.
__
The point A is the y-intercept, where the line crosses the y-axis. It tells us the value of y is 3 when x=0. So, we can write the equation in slope-intercept form as ...
y = mx + b . . . . . where m is the slope (-1) and b is the y-intercept (+3)
y = -x +3

Researchers doing a study comparing time spent on social media and time spent on studying randomly sampled 200 students at a major university. They found that students in the sample spent an average of 2.3 hours per day on social media and an average of 1.8 hours per day on studying. If all the students at the university in fact spent 2.2 hours per day on studying, with a standard deviation of 2 hours, the sampling distribution of the time spent studying has approximate distribution
Answer:
The sampling distribution of the time spent studying has an approximately normal distribution, with mean 2.2 and standard deviation 0.1414.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Each student:
Mean of 2.2 hours, standard deviation of 2 hours.
Sampling distribution of the time spent studying has approximate distribution
Sample of 200.
By the Central Limit Theorem,
Approximately normal
Mean 2.2
Standard deviation [tex]s = \frac{2}{\sqrt{200}} = 0.1414[/tex]
The sampling distribution of the time spent studying has an approximately normal distribution, with mean 2.2 and standard deviation 0.1414.

A hot air balloon is at an altitude of
100 1/5 yards. The balloon's altitude decreases
by 10 4/5 yards every minute. Determine the
number of minutes it will take the balloon to reach an altitude of 57 yards.
Answer:
It will take 4 minutes for the balloon to reach an altitude of 57 yards.
Step-by-step explanation:
Initial altitude:
100 1/5 yards = 100 + 0.2 = 100.2 yards.
Decrease per minute:
10 4/5 yards = 10 + 0.8 = 10.8 yards.
So, after t minutes, the height of the ballon is given by:
[tex]h(t) = 100.2 - 10.8t[/tex]
Number of minutes it will take the balloon to reach an altitude of 57 yards.
This is t for which [tex]h(t) = 57[/tex]. So
[tex]h(t) = 100.2 - 10.8t[/tex]
[tex]57 = 100.2 - 10.8t[/tex]
[tex]10.8t = 43.2[/tex]
[tex]t = \frac{43.2}{10.8}[/tex]
[tex]t = 4[/tex]
It will take 4 minutes for the balloon to reach an altitude of 57 yards.

The probability of drawing a blue ball from Bag A is 1/5 and the
probability of drawing a red ball from Bag B is 2/3.
What is the probability of drawing a blue ball from Bag A AND a red
ball from Bag B?
Answer:
the probability of drawing a blue ball from bag A is 1/5 and the probability of drawing a red ball from bag B is 2/3.
The probability of drawing a blue ball from Bag A and a red ball from Bag B will be 2/15.
What is the definition of probability?
Probability denotes the likelihood of something happening. It is concerned with the occurrence of an unpredicted event.
Probability can only have a value between 0 and 1. Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of events is known as the favorable event ratio.
The probability of drawing a blue ball from Bag A is, 1/5
The probability of drawing a red ball from Bag B is, 2/3.
P(A)=1/5
P(B)=2/3
The probability of drawing a blue ball from Bag A and a red ball from Bag B will be;
P(A and B)=P(A). P(B)
P(A and B)=(1/5)×(2/3)
P(A and B)=(2/15)
Hence,the probability of drawing a blue ball from Bag A and a red ball from Bag B will be 2/15.

Without factoring, determine which of the graphs represents the function g(x)=21x2+37x+12 and which represents the function h(x)=21x2−37x+12. Explain your reasoning. The graph of represents the function g(x)=21x2+37x+12. The graph of represents the function h(x)=21x2−37x+12. Because c is positive, the constant terms in each factor must have signs. Because the function has a positive value for b, the constant terms in each factor will both be which results in Response area roots, and the graph of Response area has two Response area x-intercepts. Because the function has a negative value for b, the constant terms in each factor will both be which results in Response area roots, and the graph of Response area has two Response area x-intercepts.
Answer:
The graph which represents the function g(x) = 21·x² + 37·x + 12, is described as follows;
Because 'c' is positive, the constant terms in each factor must have the same signs
Because the function has a positive value for 'b', the constant terms in each factor will both be positive which results in negative roots and the graph of the function, g(x) = 21·x² + 37·x + 12, has two negative x-intercepts
The graph which represents the function h(x) = 21·x² - 37·x + 12, we have is described as follows;
Because 'c' is positive, the constant terms in each factor must have the same signs
Because the function has a negative value for 'b', the constant terms in each factor will both be negative which results in positive roots and the graph of the function, g(x) = 21·x² + 37·x + 12, has two positive x-intercepts
Step-by-step explanation:
The given functions are;
g(x) = 21·x² + 37·x + 12
h(x) = 21·x² - 37·x + 12
For the graph which represents the function g(x) = 21·x² + 37·x + 12, we have
Because 'c' is positive, the constant terms in each factor must have the same signs
Because the function has a positive value for 'b', the constant terms in each factor will both be positive which results in negative roots and the graph of the function, g(x) = 21·x² + 37·x + 12, has two negative x-intercepts
For the graph which represents the function h(x) = 21·x² - 37·x + 12, we have
Because 'c' is positive, the constant terms in each factor must have the same signs
Because the function has a negative value for 'b', the constant terms in each factor will both be negative which results in positive roots and the graph of the function, g(x) = 21·x² + 37·x + 12, has two positive x-intercepts

A rectangle has an area 12cm². If the length of the rectangle is ( x + 1 )cm and the width is x cm, find the possible value(s) of x . Show the working please thank you
Answer:
x can be 3 or (-4) because
area of a rectangle= length × breadth
12=x×(x+1)
12=x^2+x
x^2+x-12=0
x^2 +4x-3x-12=0
x(x+4)- 3(x+4)=0
(x+4)(x-3)=0
(x+4)=0 or (x-3)=0
Therefore, x=(-4) or 3
Since, the dimensions of a rectangle cannot be negative, x=3.
Therefore, the width of a rectangle(x)=3 cm,
the length of a rectangle(x+1)=(3+1)=4 cm
