What is the slope of the line created by this equation?
Round your answer out to two decimal places
6x + 7y = 5
Answer:
-0.86
Step-by-step explanation:
What is the slope of the line created by this equation? Round your answer out to two decimal places. 6x + 7y = 5
_____________________________________________
Slope intercept form solves for y:
y = mx + b when m = slope and b = y-intercept
First, solve for y:
6x + 7y = 5
subtract 6x from both sides:
6x + 7y - 6x = 5 - 6x
7y = 5 - 6x
divide both sides by 7:
7y/7 = (5 - 6x)/7
y = 5/7 - 6/7x
rearrange right side:
y = - 6/7x + 5/7
Back to the equation: y = mx + b when m = slope and b = y-intercept
your slope is -6/7
in decimal form, rounded to two digits: -0.86

In triangle ABC, what is the measure of angle C if A = 120°, a = 25, and b = 20? Round the answer to the nearest hundredth.
The angle C = 103.85° using the sine rule and rounded to the nearest hundredth.
What is the sine rule?In trigonometry, the sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
Considering the ∆ABC, the sine rule states that;
(a/sinA) = (b/sinB) = (c/sinC)
so
25/sin120° = 20/sinB
sinB = (20 × sin120°)/25 {cross multiplication}
sinB = 0.6928
B = sin^(-1)[0.6928)] {sine inverse}
B = 43. 85°
Sum of interior angles in ∆ABC is 180° so;
C = 180° - (120° + 43.85°)
C = 180° - 76.15°
C = 103.85°
With the application of the sine rule, we can conclude that the value of the angle C is 103.85° rounded to the nearest hundredth.

you are flying a kite and the angle of elevation from the horizon is 36 if your kite string is 15 feet long, how high are you flying the kite ?
By using a trigonometric relation we will see that the height of the kite is 8.82 feet above the point where you hold the line.
how high are you flying the kite?We can view this as a right triangle, where the hypotenuse has a measure of 15 feet, we know one angle that measures 36°, and the opposite cathetus to that angle is x, the height we want to find.
We want to get the value of x, which is the opposite cathetus to the given angle, then we can use the trigonometric relation:
sin(a) = (opposite cathetus)/(hypotenuse)
Replacing what we know we will get:
sin(36°) = x/15ft
Solving this for x we get:
x = sin(36°)*15ft = 8.82ft
The height of the kite is 8.82 feet.

use the figure to complete the following statements
Step-by-step explanation:
I don't see the options and how they are written, but I can tell you the right answer in numbers :
sin(F) = 3/5 = 0.6
cos(F) = 4/5 = 0.8
sin(G) = 4/5 = 0.8
cos(G) = 3/5 = 0.6
why ?
remember the norm circle (radius 1) with ask the trigonometric functions.
the sine of an angle is the vertical height from that point in the circle arc down to x-axis.
the cosine of an angle is the length on the x-axis from the center of the circle to the point, where the sine touches the x-axis.
in any case, sine and cosine enclose the right angle (90°).
each function is now defined for the norm circle with radius = 1.
for angles in larger circles we need to divide the find lengths by the actual radius (we formality do this in the norm circle too, but a division by 1 does not change anything).
for the angles at F and G the radius is the side with the length 5.

Three people each have a tendency to lie 1/3 of the time. There is a coin flip that they all see. They all say it's Heads. What's the probability it is actually Heads
The probability is 8/9.
From the question, we have
probability = (1/3)*(1/3)*(1/3) = 1/27 chance (all of them lie)
probability = (2/3)*(2/3)*(2/3) = 8/27 chance (all of them true).
Since, they all say it's heads.
Thus, the probability of it being heads = (8/27)/ ((8/27)+(1/27)) = 8/9.
Probability:
Chance is referred to as probability. This branch of mathematics studies the probability of a random event. The value is between 0 and 1. Probability is a concept that mathematics has adopted to predict the likelihood of particular events. Probability is just the measure of how likely something is to occur. With the help of this fundamental theory of probability, which is also used to describe the probability distribution, you will be able to comprehend the possible results for a random experiment. How likely something is to occur can be determined using probability. It might be challenging to predict many things with complete certainty. We can only predict whether an event will occur or how likely it is using it, not if it will actually occur.

What is normal distribution?A normal distribution is a data set design in which the majority of values cluster around the middle of the range and the remainder taper off symmetrically toward either end. Data in a normal distribution are symmetrically distributed and have no skew. The majority of values cluster around a central location, with values decreasing as one moves out from the center. In a normal distribution, the measures of central tendency (mean, mode, and median) are all the same. The normal distribution, like any other probability distribution, defines how the values of a variable are distributed. Because it properly captures the distribution of values for many natural occurrences, it is the most important probability distribution in statistics.

A school had 1 200 students last year and only 1 080 students this year. What was the percent decrease in the number of students?
The percentage decrease in the number of students in the school was 10%.
What is the percentage?The percentage refers to the ratio or proportion of students that reduced the number of the school population for the present year in comparison to last year's.
We can compute the percentage by finding the decrease in population and taking the result as a numerator of the total number in the last year and multiplying the result by 100.
Percentages represent fractional values and are usually depicted by the percentage sign (%).
The total number of students in the school last year = 1,200
The total number of students in the school this year = 1,080
The decrease in the number of students = 120 (1,200 - 1,080)
The percentage decrease = 10% (120/1,200 x 100)
Thus, we can conclude that the school population decreased by 10%.

What is an equation of the line that passes through the points (4, −2) and (2, 3)?
The equation of the line, in slope-intercept form, that passes through
(4, 2) and (-2, -3) is y = 5/6 x - 4/3.
What is slope-intercept form?
The meaning of slope-intercept form is the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
Using two points and slope-intercept form we can find the equation of the line.
According to the given question:
The formula to find the slope of two points (x₁, y₁) and (x₂, y₂) is
m = (y₂ - y₁) / (x₂ - x₁)
The points given are (4, 2) and (-2, -3)
m = (-3 - 2) / (-2 - 4)
m = -5/ -6
m = 5/6
Now using the slope and the point (4, 2) the y intercept is
y = mx + b
2 = 5/6 (4) + b
2 = 10/3 + b
By further calculation,
b = 2 - 10/3
Taking LCM
b = (6 - 10)/3 = -4/3
By writing the equation in slope intercept form
y = mx + b
y = 5/6x - 4/3
Therefore, the equation of the line in slope intercept form is
y = 5/6 x - 4/3.
