225 degrees-495 degrees==========================================================
Explanation:
To find a coterminal angle, we can either add or subtract 360 from the given angle.
Adding on 360 gets us -135+360 = 225
Adding another copy of 360 gets us 225+360 = 585, which isn't on the list. It exceeds the largest value 495, so we can stop adding on copies of 360.
----------
Let's go back to -135 and subtract 360 to see what we get
-135 - 360 = -495
Repeat again to get
-495-360 = -855
but that's not on the list. We can stop here because -495 is the smallest item on this list.
------------
The reason why we add/subtract 360 is because we're rotating a full 360 degrees to get to another coterminal angle. The angle -135 is coterminal to 225 degrees as they both point directly in the southwest direction.
As another example, the angle 90 degrees and 90+360 = 450 degrees are coterminal since they both point directly north.

Answer:
1861.39 cm²
Step-by-step explanation:
Given:
d = 15 cm
radius (r) = ½(15) = 7.5 cm
Height = 32 cm
Surface area of a cylinder = 2πrh + 2πr²
Plug in the values
Surface area = 2*π*7.5*32 + 2*π*7.5²
= 1861.39 cm²
An article included a summary of findings regarding the use of SAT I scores, SAT II scores, and high school grade point average (GPA) to predict first-year college GPA. The article states that "among these, SAT II scores are the best predictor, explaining 17 percent of the variance in first-year college grades. GPA was second at 15.6 percent, and SAT I was last at 13.3 percent." If the data from this study were used to fit a least squares line with y = first-year college GPA and x = high school GPA, what would the value of r2 have been?
Answers
Answer:
0.156
Step-by-step explanation:
Given that :
% of Explained variance by certain predictors of first year college grade :
SAT 11 scores = 17%
GPA = 15.6%
SAT 1 = 13.3%
Fitting a least squares line :
y = First year college GPA
x = high school GPA
THE r² value which is Coefficient of determination is the percentage of explained variance given by the regression line. The r² value of GPA will the as given above 15.6%
r² = 15.6% = 15.6/100 = 0.156

What is the population of interest for this study?
Answers
Answer:
the monthly rents of the apartments
Step-by-step explanation:
In the field of statistics, the population of interest may be defined as the group or the population from which the experimenter or the researcher tries to make conclusions or draw their results.
In the context, I am interested to study the cost of the rented house that is more than others in the West Campus area.
So I recorded the monthly rents of the apartments from a sample of 30 one bedroom apartments.
Therefore, the population of interest for my study here is the monthly rents recorded from the sample of one bedroom apartments.

Answer:
Angle 1 = 35
Angle 2 = 30
Answer B
Step-by-step explanation:
Angle 1)
You know the total angles in a triangle are 180
You also know that the angle across from 1, next to 115 has to be 180-115 (65) or , this gives you
180-80-(180-115)= 35
Angle 2 )
You know the total angles in a triangle are 180
You also know that the angle across from 85, next to 115 is the same value 65 as it was for the calculation of angle 1.
so this means
180-85-65 = 30

7. A particular compound decays according to the equation y = ae-0.0736t, where tis in days. Find the
half-life of this compound.
a. about 9.1 days b. about 9.4 days
c. about 6.8 days d. about 7.4 days
Answers
Answer:
b. about 9.4 days
Step-by-step explanation:
Amount of the compound:
The amount of the compound after t days is given by the following equation:
[tex]y(t) = ae^{-0.0736t}[/tex]
The initial amount is:
[tex]y(0) = a[/tex]
Half-life:
t for which [tex]y(t) = 0.5a[/tex]. So
[tex]y(t) = ae^{-0.0736t}[/tex]
[tex]0.5a = ae^{-0.0736t}[/tex]
[tex]e^{-0.0736t} = 0.5[/tex]
[tex]\ln{e^{-0.0736t}} = \ln{0.5}[/tex]
[tex]-0.0736t = \ln{0.5}[/tex]
[tex]t = -\frac{\ln{0.5}}{0.0736}[/tex]
[tex]t = 9.42[/tex]
So about 9.4 days, and the answer is given by option b.

Answers
Answer:
x = -7, y = -1
Step-by-step explanation:
Solve the following system:
{3 y - 2 x = 11 | (equation 1)
2 y + 3 x = -23 | (equation 2)
Swap equation 1 with equation 2:
{3 x + 2 y = -23 | (equation 1)
-(2 x) + 3 y = 11 | (equation 2)
Add 2/3 × (equation 1) to equation 2:
{3 x + 2 y = -23 | (equation 1)
0 x+(13 y)/3 = -13/3 | (equation 2)
Multiply equation 2 by 3/13:
{3 x + 2 y = -23 | (equation 1)
0 x+y = -1 | (equation 2)
Subtract 2 × (equation 2) from equation 1:
{3 x+0 y = -21 | (equation 1)
0 x+y = -1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -7 | (equation 1)
0 x+y = -1 | (equation 2)
Collect results:
Answer: x = -7, y = -1

Answers
Answer:
Is this the full question?
Hi ^^
--------------------
A recipe calls for 3/4 cup of sugar and 2/3 cup of butter, so the sugar to butter ratio is (3/4)/(2/3) = (3/4)(3/2) = 9/8. This ratio implies that 1 cup of butter requires 9/8 cups of sugar.
Since you use 1½ = 3/2 cups of butter, you will need
(3/2)(9/8) = 27/16 cups of sugar.
