The time spent on homework will be naturally more an explanatory variable and exam grade a response variable.

The Linear equation for a scatter plot y = mx+b has two variables i.e., a Dependent Variable [Y] and an Independent variable [X] .

A student who spends more time on his work and do it nicely will automatically get good exam grade . On the other side, a student who did'nt dedicate much time to the homework and carelessly does it , will obviously score a low exam grade.We can see that the exam grade is dependent on the time spent on the homework which naturally makes exam grade a response variable and time spent on home a independent thus an explanatory variable.

Hence, the time spent on homework will be naturally more an explanatory variable and exam grade a response variable.

Answer:

The answer is A. 3 3/5   and     B. 2 8/5

:D

explanation:

It couldn't be 5/18 because that is less than the fraction

And it could not be 3 because 5 (the denominator) times 3, is not 18 (numerator), it is 15.

SO.... now that we narrowed those answers down we have to look at the mixed fractions..  

3 3/5 into an improper fraction would be  18/5 because 3/5 is 15, plus 3 is 18.

2 8/5 into an improper fraction would be 18/5 because 2x5 is 10, plus 8 is 18.

therfore A and B are your answers, hope this helps!

Answer:

\(y=0.400x+-0.800\)

Step-by-step explanation:

Given the following question:

point A = (-3, -2)
point B = (2, 0)

To write the equation of the line that passes through two points we have to write the points in slope intercept form.

Formula for slope intercept:

\(y=mx+b\)

M is equal to the slope of the two points, so first we need to fine the slope of the two points.

\((-3,-2)=(x1,y1)\)
\((2,0)=(x2,y2)\)

\(m=\frac{y2-y1}{x2-x1}\)
\(m=\frac{0--2}{2--3} =\frac{2}{5}\)
\(m=\frac{2}{5} =0.400\)

\(y=mx+b\)
\(y=-2\)
\(m=0.400\)
\(x=-3\)
\(-2=0.400(-3)+b\)
\(0.400\times-3=-1.20\)
\(-2+1.2=-0.800\)
\(b=-0.800\)

\(y=0.400x+-0.800\)

Hope this helps.

Step-by-step explanation:

it will take approximately 29.823 seconds to produce 1.0 g of silver metal by the electrolysis of an AgNO3 solution using a current of 30 amps.

To determine how many seconds will be required to produce 1.0 g of silver metal by the electrolysis of an AgNO3 solution using a current of 30 amps, we need to follow these steps:

1. Calculate the number of moles of silver (Ag) in 1.0 g:
1.0 g / 107.87 g/mol (molar mass of Ag) = 0.00927 mol of Ag

2. Use Faraday's law of electrolysis to find the total charge needed:
Total charge (Q) = n × F
where n is the number of moles of Ag (0.00927 mol) and F is the Faraday constant (96,485 C/mol).
Q = 0.00927 mol × 96,485 C/mol = 894.7 C (Coulombs)

3. Determine the time (t) required to pass the total charge at a current of 30 amps:
t = Q / I
where Q is the total charge (894.7 C) and I is the current (30 A).
t = 894.7 C / 30 A = 29.823 seconds

So, it will take approximately 29.823 seconds to produce 1.0 g of silver metal by the electrolysis of an AgNO3 solution using a current of 30 amps.

The slope of the line through (-9,6) and (-6,-9) is -5

Now, According to the question:

Let's know:

What is slope and example?

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

The formula for the slope of a line when two points (coordinate pairs)

\((x_1,y_1)\) and \((x_2,y_2)\) are given is :

\(m = \frac{y_2-y_1}{x_2-x_1}\) ,  where m denotes the slope of the line.

Applying this formula, we get:

\(m = \frac{-9-6}{-6-(-9)}\)

\(m = \frac{-15}{-6+9}\)

m = \(\frac{-15}{3}\)

m = -5

Hence, The slope of the line through (-9,6) and (-6,-9) is -5.

(15)²= (9)²+(BC)²

225=81+(BC)²

BC=√144

BC=12

Answer:

B:12

Step-by-step explanation:

The length of BC is 12 because we can use the Pythagorean theorem to solve this. First, we know what the hypotenuse is 15 and the one of the side lengths which is 9. he equation to solve this is h^2-a^2 when h is 15 and a=9. So, we we plug in the info, we get 15^2-9^2 which is 15*15-9*9 which is 225-81 and that is 144. We are not done yet because we need to find the square root of 144 since we squared 15 and 9 in the first place. The √144 is 12 because 12*12 is 144. Now, we have to check! The equation is a^2+b^2=h^2 when a=12, b=9, and h=15! So, it will be 12^2+9^2=15^2 which simplifies to 144+81=225 and that is true!! So thats why it is B. Hope this helps!!!!!!

On [0,∞] the function grows, whereas on [-∞, 0], it shrinks. f has absolute minimum value is 0, and it also has the same relative minimum value (0,0).

On the graph, you are able to see a "open circle" at it when x< 0. (0, 0).

There consequently no absolute maximum value of f due to the graph's infinitely high y values.

Answer:

1.616

Step-by-step explanation:

Too easy to explain. Sorry.

Answer:

1/15

Step-by-step explanation:

The two events are not dependent so we can not use multiplication rule.

So P(getting a quarter on the first try) is

\( \frac{3}{10} \)

Assuming we get a quarter, we would be left with 9 coins, and only 2 quarters, so

P(getting a quarter second time in a row)

\( \frac{2}{9} \)

Multiply the two

\( \frac{3}{10} \times \frac{2}{9} = \frac{6}{90} = \frac{1}{15} \)

By using the concept of confidence interval, it can be concluded that-

Confidence interval = (0.1954, 0.2286)

We are 95 % confident that the true proportion of working adult who

were very concerned that their job will be automated, outsourced, or otherwise made obsolete in the next 5 years falls within this interval

Second option is correct

What is confidence interval?

Suppose there is a parameter which is unknown. Confidence interval will give the range of this unknown parameter.

Let the unknown  parameter be θ,  A confidence interval for the parameter θ is an interval (u, v)

where P(u < θ  < v) = 1 - α, where P is the probability

α is called level of significance

Total number of working adults = 2305

Number of working adults surveyed = 489

Proportion of sample surveyed = \(\frac{289}{2305}=\) 0.212

Standard error = \(\sqrt{\frac{0.212 \times ( 1- 0.212)}{2305}} = 0.0085\)

At 95% confidence interval, z value = 1.96

Margin of error = 1.96 \(\times\) 0.0085 = 0.0166

Lower bound for the confidence interval = 0.212 - 0.0166 = 0.1954

Upper bound for the confidence interval = 0.212 + 0.0166 = 0.2286

Confidence interval = (0.1954, 0.2286)

Now since this is a problem on confidence interval, so a concept of confidence will come into question.

So, we are 95 % confident that the true proportion of working adult who

were very concerned that their job will be automated, outsourced, or otherwise made obsolete in the next 5 years falls within this interval

Second option is correct

When you want to round to the units place, you look at the digit in the number that is in the place to the right of that: the tenths place. Here, that digit is 7, which is more than 4. Because that digit is more than 4, 1 is added to the units place and all the digits to the right of that are dropped.  

This gives you 59,424 +1 = 59,425.    

If the tenths digit were 4 or less, no change would be made to values in the units place or to the left of that. The tenths digit and digits to the right would be dropped.

Using it's concept, considering the tree diagram, the probability of event C is given as follows:

P(C) = 0.26.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Each node at the tree is a multiplication, hence the probability of event C is given as follows:

P(C) = 0.6 x 0.3 + 0.4 x 0.2 = 0.18 + 0.08 = 0.26.
