Answer: 1/4
Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is and slope can be found using the ratio rise/run between any two points that are on that line.
So for the line you see here, let's use these two points to find its slope.
Let's go from left to right.
To get from the point that has the coordinates (0,1) to (4,2),
we rise 1 unit and run 4 units to the right and we end up the other point.
So the slope of this line is 1/4.

What is the slope form equation?
Answers
Answer:
y= mx +c
Step-by-step explanation:
The point- slope form of an equation is
y= mx +c, where m is the gradient and c is the y-intercept.
You can find the value of m by using the gradient formula.
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
Then substitute the value of m found into the equation. Next substitute a pair of coordinates the line passes through to find the value of c. Substitute the value of c and you will obtain the point-slope form equation of the line.
Here's an example.
Point-slope form of an equation passing through (1, 2) and (5, 6).
① Finding gradient, m.
[tex]m = \frac{6 - 2}{5 - 1} \\ m = \frac{4}{4} \\ m = 1[/tex]
② Substitute value of m into equation.
y= 1x +c
y= x +c
③ Substitute a pair of coordinates.
when x=1, y=2,
2= 1 +c
c= 2 -1
c= 1
Thus the equation of the line is y= x +1.
You may already know that "y+MX+b" form called the slope-intercept form of the equation of a line. It is the same equation in a different form. The 'b' value called the y intercept is where the line crosses the y- axis

What is a fraction?A fraction represents a part of a number or any number of equal parts.
Multiplication is the mathematical operation that is used to determine the product of two or more numbers.
We need to express 25 minutes as a fraction of 2 hours in its simplest form.
Since we know that 1 hour = 60 minutes
2 hours = 60 x 2 = 120 minutes
then:
25 minutes / 120 minutes
25/5= 5
Thus 120/5 = 24
Hence, The simpliest form of 25 minutes as a fraction of 2 hours is 5/24

Answer for the first box = 6000
Answer for the second box = 1.004
Answer for the third box = 720
So the full equation is [tex]C(t) = 6000(1.004)^{12t} + 720t[/tex]
=======================================================
Explanation:
The compound interest formula is
A = P( 1+r/n )^(n*t)
where
P = amount deposited (principal)r = interest rate in decimal formn = number of times we compound per year (compounding frequency)t = number of yearsIn this case,
P = 6000r = 4.2% = 4.2/100 = 0.042n = 12 since there are 12 months in a year (it explains the 12 in the exponent in the answer)t = unknown, we leave this as isSo we go from this
A = P( 1+r/n )^(n*t)
to this
A = 6000( 1+0.042/12 )^(12t)
A = 6000(1.0035)^(12t)
A = 6000(1.004)^(12t)
The 1.0035 rounded to 1.004 when rounding to three decimal places, as the instructions mention.
So far we only considered the amount placed into the bank. But there's also the amount placed in the safe at home. We have $60 placed in here per month. This is 60*12 = 720 dollars per year. If t years go by, then a total of 720t dollars is put in the safe.
----------
So in summary we found
[tex]b(t) = 6000(1.004)^{12t}[/tex] = amount in savings account after t years go by
[tex]h(t) = 720t[/tex] = amount in safe after t years
leading to
[tex]C(t) = b(t) + h(t) = 6000(1.004)^{12t} + 720t[/tex]
In order to predict y-values using the equation of a regression line, what must be true about the correlation coefficient of the variables?
Answers
Answer: The correlation between variables must be significant
Step-by-step explanation: In order to make reliable predictions using the equation of a regression model, the correlation Coefficient between the dependent and independent variables must be significant (that is a correlation Coefficient value close to either 1 or - 1). This is because the range of value of the correlation Coefficient is between - 1 to +1 and the closer the correlation Coefficient value is to either of these numbers, depicts the strength of the relationship which exists between them hence, enabling us to make good and accurate predictions which are close to the actual value.
Regression Analysis is a statistical and reliable process for making predictions using the regression model.
The correct option is:
Option B. The correlation between variables must be significant
The regression line can be explained as:
1. The correlation coefficient between the dependent and independent variables must be significant.
2. The correlation coefficient value should be near 1 or -1.
3. Thus, the values closer to - 1 and +1 will depict the strength of the relationship between the coefficient values.
Thus, regression lines help to predict accurate and reliable results that are close to the actual value.

Answers
Answer:

Step-by-step explanation:
Mid point of (-10, 5) and (-5, 0).
Other point (-8, 4).
To find:
Equation of line in standard form that connect the mid point and other point.
Solution:
Mid point formula is given as:
[tex]x = \dfrac{x_1+x_2}{2}\\y = \dfrac{y_1+y_2}{2}[/tex]
[tex]x = \dfrac{-10+-5}{2} = -7.5\\y = \dfrac{5+0}{2} = 2.5[/tex]
Now, the two points are: (-7.5, 2.5) and (-8, 4)
Slope intercept form of line is given as:
[tex]y = mx+c[/tex]
[tex]m=\dfrac{4-2.5}{-8-(-7.5)} = -3[/tex]
So, the equation of line is:
[tex]\Rightarrow y =-3x+c[/tex]
Putting (-8, 4) to find c:

suppose y varies jointly as x and z. Find y when x=5 and z=6, if y=144 when x=6 and z=10
Answers
Answer:
y=72
Step-by-step explanation:
y varies jointly as x and z
y=k*x*z
Where,
k= constant of proportionality
y=144, x=6, z=10
y=k*x*z
144=k*6*10
144=60k
Divide both sides by 60
144/60=k
2 24/60=k
2 6/15=k
2 2/5=k
k=12/5
Find y when x=5 and z=6
y=k*x*z
y=12/5*5*6

A 30 ft cable extends from the floor of the lookout of a fire tower. The table is anchored from the ground 18 ft away from the base of the tower. What is the Hight of the floor of the look out tower.
Answers
=================================================
Explanation:
Assume the ground is completely flat and level. We have a right triangle with hypotenuse 30, and the horizontal base leg is 18. The vertical leg is unknown, so we'll call it x.
Use the pythagorean theorem to solve for x
a^2+b^2 = c^2
x^2+18^2 = 30^2
x^2 + 324 = 900
x^2 = 900 - 324
x^2 = 576
x = sqrt(576)
x = 24
The height of the tower's floor is 24 feet.

Step-by-step explanation:
Given, IQ scores are approximately normally distributed with a mean of 100 and standard deviation of 15
Let X denotes the IQ score.
Then, the proportion of people with IQs above 130 is
[tex]P(X>130)=P(\dfrac{X-mean}{ standard\ deviation}>\dfrac{130-100}{15})\\\\= P(Z>2)\ \ \ \[Z=\dfrac{X-mean}{ standard\ deviation}][/tex]

The temperature in Anchorage, Alaska at 6 a.m. was 2°C. If the temperature drops 2 degrees each hour, what is the temperature in degrees Celsius at 2:00 pm
Answers
Answer:
-14°C
Step-by-step explanation:
6 + 8 = 14
So in 24 hour time that would be 2pm
From 6am to 2pm is 8 hours
If the degrees is going down by 2 you would times the 8 by 2 because it is doubled
That = 16
Then you'll minus 16°C from the 2°C
2°C - 16°C
= -14°C
