[tex]x = - \frac{494}{3}[/tex] [tex]= - 164\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]75 + \frac{3}{8} x = 13\frac{1}{4}\\\\75 + \frac{3}{8} x = \frac{53}{4}\\\\\frac{3}{8}x = \frac{53}{ 4} - 75\\\\\frac{3}{8}x = \frac{53-300}{4}\\\\\frac{3}{8}x = - \frac{247}{4}\\\\x = -\frac{247 \times 8}{4 \times 3} \\\\x = -\frac{494}{3}[/tex]
Cricket chirps: Temperature Anyone who has been outdoors on a summer evening has probably heard crickets. Did you know that it is possible to use the cricket as a thermometer? Crickets tend to chirp more frequently as temperatures increase. This phenomenon was studied in detail by George W. Pierce, a physics professor at Harvard. In the following data, x is a random variable representing chirps per second and y is the random variable representing temperature (F). These data are also available for download at the online study center.X 20.0 16.0 19.8 18.4 17.1 15.5 14.7 17.1Y 88.6 71.6 93.3 84.3 80.6 75.2 69.7 82.0X 15.4 16.2 15.0 17.2 16.0 17.0 14.4Y 69.4 83.3 79.6 82.6 80.6 83.5 76.3Complete parts (a) through (e), given ?x= 249.8, ?y=1200.6, ?x^2= 4200.56, ?y^2= 96,752.86, ?xy= 20,127.47 and r = 0.835.A) Draw a scatter diagram displaying the data.B) Find X- bar, Y- bar, a and b. Then find the equation of the least squares line y=a+bx.C) Graph the least squares line on your scatter diagram. Be sure to use the point ( X-bar, Y- bar) as one of the points on the line.D) Find the value of the coefficient of determination r ^2. What percentage of the variation in y can be explained by the corresponding variation in x and the least squares line? What percentage is unexplained?E) What is the predicted temperature when x= 19 chirps per second.
Answer:
Kindly check explanation
Step-by-step explanation:
Using technology on the data above, the least square regression equation obtained is ;
y = 33.4528+2.7975x
Where, slope = 2.7975 ; Intercept = 33.4528
x = chirps per second, independent variable
y = temperature, predicted variable.
The Correlation Coefficient, r = 0.71
The Coefficient of determination, r² = 0.71² = 0.5041
The percentage of variation in y due to regression is the r² value, which is about 50.41%
Hence, the percentage variation in temperature due to the regression line is 50.4, while the rest is due to other factors.
Predicted temperature, y when x = 19 ;
Put x = 19
y = 33.4528+2.7975(19)
y = 86.60°

Which value of n would make 3√n=8
Answer:
n = 64/9
Step-by-step explanation:
3√n=8
Divide each side by 3
3/3√n=8/3
sqrt(n) = 8/3
Square each side
(sqrt(n))^2 = (8/3)^2
n = 64/9
Answer:
n = 64 / 9
Step-by-step explanation:
3√n = 8
Divide both side of equation by 3
3√n / 3 = 8/3
√ n = 8 / 3
Square both side of equation
√n² = √(8/3)
n = 64/9

what is 3/5 minus 5/11
Answer:
0.14545454545 Maybe
Step-by-step explanation:
Answer:
8/55
Step-by-step explanation:
The first thing you need to do is find a common denomintor.
The first denominator is 5, the other is 11.
If you multiply these together, you will get 55. This can not be reduced and still be divisable by 5 and 11, so this is your new denominator.
So for the 3/5 multiply both top and bottom by 11, since thats how many times bigger the denominatir needs to be:
3*11/5*11= 33/55
Then for 5/11 multiply both top and bottom by 5, since thats how many times bigger the denomator is to make 55:
5*5/11*5=25/55
Now we have:
33/55-25/55
When subtracting fractions, you are only subtracting the two numerators, and the denominators are unaffected:
33-25/55=8/55
So 8/55 is your answer.
Hope this helps!

THANK YOU SO MUCH FOR YOUR HELP
Answer:
Step-by-step explanation:
If you have a square of side [tex]l[/tex], its diagonal would be [tex]l\sqrt{2}[/tex], and its area [tex]l^2[/tex]
If the big square has a area of 900, this implies that its side is [tex]\sqrt{900}[/tex], so the two diagonal of squares 2 and 4 added together would be [tex]\sqrt{900}[/tex], therefore one diagonal wold be [tex]\frac{\sqrt{900}}{2}[/tex]. and its side [tex]\frac{\sqrt{900}}{2}\frac{1}{\sqrt{2}}[/tex]. The area (of one square) is [tex](\frac{\sqrt{900}}{2}\frac{1}{\sqrt{2}})^2=\frac{225}{2}[/tex]
finally the two areas combined (squares 2 and 4) would be 225
Answer:
425
Step-by-step explanation:
I used help from the guy above me to find 2 and 4 so look at theirs for those. (Thank You). For 1 and 3. Each one is 1/9 of the big square. So each one is 1/9*900=100 100*2=200. And then we add 225+200=425.
Hope this helps :)
The Fighting Hens' record has improved every year. The 2016 team won 3

than the 2016 team. If the 2017 team won 20 games, how many did the 2015
team win?
Answer:
15
Step-by-step explanation:
just calculate backwards
20 -2 -3
Answer:
The answer would be 15.
Step-by-step explanation:
I agree with the previous answer, in these cases you just calculate backward.
You start out with 20, then it states 2017 team won 2 more games, so you subtract 2. So now we know the 2016 team won 18 games.
Next we subtract 3 to get how many wins the 2015 team got. 18 - 3 is 15.
The answer would be 15.

y=-16x^2+239x+127
Answer:
7.47 seconds
Step-by-step explanation:
From the quadratic equation the x coordinate of the vertex is
x = -b/(2a)
---------------------------
y = -16x² + 239x + 127
x = -239/ ( 2 * (-16) )
x = -239 / (-32)
x = 7.46875
Rounded

Which point is a reflection of 01-4, -6) across the x-axis and the -axis?
a) point a
b) point b
c)point c
d)point d
Answer:
If we have a point (x, y), a reflection across the x-axis converts the point to (x, -y)
While a reflection across the y-axis converts the point to (-x, y)
Then if we apply both of these transformations to our point, the reflection of (x, y) across the x-axis and then across the y-axis is (-x, -y)
Then the reflection of (-4, -6) across these two axes, is:
(- (-4), - (-6)) = (4, 6)
The correct option is B.

Possible answers, 35, 30, 90,64
Answer:
30
Step-by-step explanation:
this is a right-angled triangle.
as we can see on the graph and the coordinate units,
AB = 4
BC = 7
=>
AC² = AB² + BC² = 4² + 7² = 16+49 = 65
AC = sqrt(65)
now, in every triangle there are certain ratios equal to each other.
a/sin(A) = b/sin(B) = c/sin(C)
a is here BC
b is here AC
c is here AB
and we know B = 90 degrees
sin(90) = 1
so, we have
sqrt(65)/1 = 4/sin(C)
sqrt(65) = 4/sin(C)
sin(C) = 4/sqrt(65) = 0.496138938...
C = 29.7448813...
the closest answer option is 30.
In 2006 the number of tickets sold was 210.
The ratio Number of adult tickets: Number of student tickets was 23:19.
How
many
adult tickets were sold?
Answer:
115
Step-by-step explanation:
There were 115 adult tickets were sold.
What is ratio?A ratio shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six.
Given that, the number of tickets sold was 210. The ratio Number of adult tickets: Number of student tickets was 23:19.
Let the number of tickets sold for adults be 23x and for students be 19x
Therefore, 23x+19x = 210
42x = 210
x = 210/42
x = 5
So, Number of adult tickets = 5x23 = 115
Hence, There were 115 adult tickets were sold.
