Answer:
The answer is below
Step-by-step explanation:
A linear function is a function in the form y = mx + b, where y and x are variables, b is the y intercept (value of y at x = 0) and m is the slope (rate of change).
Let x represent the year and y represent the amount of rainfall in inches. The linear function can be gotten by selecting any two pair of points from the table in the form (x, y).
Let us use the points (2004, 62.33) and (2007, 60.74). The equation is gotten using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-62.33=\frac{60.74-62.33}{2007-2004}(x-2004) \\\\y-62.33=-0.53(x-2004)\\\\y-62.33=-0.53x+1062.12\\\\y=-0.53x+1124.45[/tex]
The graph is plotted using geogebra.
The average rainfall from 2004 to 2013 is 59.945
Given data of rainfall:
2004 62.33
2005 61.8
2006 61.27
2007 60.74
2008 60.21
2009 59.68
2010 59.15
2011 58.62
2012 58.09
2013 57.56
what is the average value?it is the sum of all the observations divided by the total number of observations.
average rainfall A
(62.33+61.8+61.27+60.74+60.21+59.68+59.15+58.62+58.09+57.56)/10
A= 59.945
thus, the average rainfall from 2004 to 2013 is 59.945

What is the final amount if 784 is decreased by 1% followed by a 4% increase?
Give your answer rounded to 2 D
Answer:
807.21
Step-by-step explanation:
for the 1 % decrease
1/100 × 784 = 7.84
784 - 7.84 = 776.16
then 4% increase
4/100 × 776.16 = 31.0464
776.16 + 31.0464= 807.2064

Dennis read 30% of his book on Tuesday and of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Answer:
1/2x
Step-by-step explanation:
Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Total pages of the book = x
Tuesday = 30%
= (30/100)x
= 3/10x
Wednesday = 1/5x
3/10x + 1/5x
= 3x+2x/10
= 5/10x
= 1/2x
what fractional part of the book did he have left to read after Wednesday
= x - 1/2x
= 2x-x/2
= x/2
= 1/2x

WEST is a parallelogram. If mze = (3x – 18)º, mzw
find the value of y and mus.
(15y + 6)°, and m2T = (2x + 6),
9514 1404 393
Answer:
m∠W = m∠S = 126°
m∠E = m∠T = 54°
x = 24
y = 8
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so we have ...
∠E = ∠T
3x -18 = 2x +6
x = 24 . . . . . . . . . add 18-2x
Then the measure of these angles (in degrees) is ...
∠E = ∠T = 2x+6 = 2(24) +6 = 54
__
The adjacent angle W is supplementary to either of these:
∠W = 180° -∠E
15y +6 = 180 -54
15y = 120
y = 8
∠W = ∠S = 126°
Answer:
y = 8
Angle S= 126°

During the morning commute 60 cars and 12 trucks passed through the intersection. What is the ratio of cars to trucks?
Answer: 60:12, 60/12, or 60 to 12.
Step-by-step explanation:
To find the ratio, we must find 2 values. The values in this case is 60 and 12. 60 being cars and 12 being trucks.
So to write the ratio, we must put the cars first, then the trucks second.
So 60 first, and 12 second.
And remember, there are 3 ways to write ratios.
So we can write it like 60:12, 60/12, or 60 to 12.
The answers are 60:12, 60/12, or 60 to 12.

A shoe store buys a shipment of nike shoes that cost $70 each to the purchases. They want to markup their prices for the customers by 30%. How much would the customer pay for a pair of nikes
Given :
A shoe store buys a shipment of Nike shoes that cost $70 each to the purchases.
They want to markup their prices for the customers by 30%.
To Find :
How much would the customer pay for a pair of Nikes.
Solution :
C.P = $70 .
It is given that selling price is 30% more than the S.P.
So, S.P = C.P + C.P×0.30
S.P = C.P×1.30
S.P = 70×1.30
S.P = $91.
Therefore, the customer would pay $91 for a pair.
find the value of X round to the nearest tenth
Given:
In a right angle triangle triangle, the length of hypotenuse = 47 units.
One of the acute angle = 17°.
Opposite side of the given angle = X
To find:
The value of X. Round to the nearest tenth.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
A right triangle is crated with the help of dotted lines. In this triangle,
[tex]\sin (17^\circ)=\dfrac{X}{47}[/tex]
[tex]0.2923717=\dfrac{X}{47}[/tex]
Multiply both sides by 47.
[tex]0.2923717\times 47=X[/tex]
[tex]13.74147=X[/tex]
[tex]X\approx 13.7[/tex]
Therefore, the approximate value of X is 13.7 units.
