Answer:
y = -5/4x + 2 1/4
Step-by-step explanation:
you would start by changing the equation to point intercept form
4x + 1 = 5y
4/5y + 1/5 = y
then you fill in the points and change the slope to -5/4 (reciprocal and opposite sign)
-4 = -5/4(5) + b
-4 = -6.25 + b
2.25 = b
a and b together can do a work in 10 days B and C together can do the same work in 15 days a b and c together can do the same work in 8 days then how many days can B alone do this work

At the U.S. Open Ternis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 97 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph. Assume that the statistician also gave us the information that the distribution of the serve speeds was mound-shaped and symmetric. What proportion of the player's serves was between 110 mph and 136 mph

Option C is the only table that represents a data set that could be fit to a normal distribution curve.
In a normal distribution, the data is symmetrically distributed around the mean, and the percentages decrease as you move away from the mean.
Option C exhibits this characteristic, where the percentages are highest at the mean values (5, 6, 9, 10) and decrease as you move away from the mean.
Where as the tables in options A, B, and D do not exhibit the characteristics of a normal distribution as the percentages do not decrease symmetrically away from the mean values.

The sum of the fifth and sixth term of an AP is 30.If the third term is 5.Find the first term.
Answer:
The first term is -3.
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.
The nth term is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term.
If we have the mth term instead of the first, we have:
[tex]a_n = a_m + (n-m)d[/tex]
We have the third term, and need the fifth and the sixth:
So we write both the fifth and the sixth in function of the third, then:
[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]
[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]
The sum of the fifth and sixth term of an AP is 30
We use this to find [tex]d[/tex]. So
[tex]a_5 + a_6 = 30[/tex]
[tex]5 + 2d + 5 + 3d = 30[/tex]
[tex]5d + 10 = 30[/tex]
[tex]5d = 20[/tex]
[tex]d = \frac{20}{5} = 4[/tex]
First term:
The third term is:
[tex]a_3 = a_1 + 2d[/tex]
Since [tex]a_3 = 5, d = 4[/tex]
[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]
The first term is -3.

Answer:
The last one: 70/100 = x/80
And 56 free throws.
Explanation:
70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.
[tex]\frac{70}{100} = \frac{x}{80}[/tex]
The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.
4/5 * 70 is 56

Shandra claims it will take them about 50 minutes working together, because 50 is the mean of 40 and 60. Which best describes Shandra’s claim?
Answer: CCCCCC
Step-by-step explanation:
It would take 24 minutes to sand the table working together.
What is an Equation?An equation is used to show the relationship between two or more variables and numbers.
It would take Shandra 40 minutes (2/3 hours) to sand a table while it would take kelly 1 hour.
Let t be the time it would take to sand the table working together. Hence:
(1/(2/3) + 1/1)t = 1
(3/2 + 1)t = 1
2.5t = 1
t = 0.4 hours = 24 minutes
It would take 24 minutes to sand the table working together.

Additional comment
The quadrilateral formed by the tangents and the radii to the points of tangency has a total interior angle measure of 360°. The angles where the radii meet the tangents are 90°, so the sum of the external angle and the central angle is 360° -90° -90° = 180°. That is, the external angle and the central angle are supplementary.
