Answer:
Point C' coincides with point E.
point D' coincides with point F.
Step-by-step explanation:
Find the value of angle O in triangle ΔBOC where O is the center of the hexagon. Once you find it, devide it by the total value of counterclockwise rotation (240°) to find how many times the point labaled C moves to the left. The value of angle O in triangle ΔCOD is the same as the value of angle O in triangl we ΔBOC, so the amount that point D moves to the left is the same.

Solve this system of equations.
2x + 6y = −6,
4x − 3y = −12
What is the solution to the system of equations?
Answers
Answer:
x = -3 and y = 0
Step-by-step explanation:
It would be more direct to apply elimination in this problem, rather than substitution:
2x + 6y = -6 ⇒ 2x + 6y = -6 ⇒ 10x = - 30
+ 2(4x - 3y = -12) + 8x - 6y = -24
Now let us solve for x through simply algebra:
10x = -30,
x = -3
Substitute this value of x into the first equation to get the value of y:
2( -3 ) + 6y = -6,
-6 + 6y = -6,
6y = 0,
y = 0
Answer:
-3 and 0

According to a Pew Research Center report from 2012, the average commute time to work in California is 27.5 minutes. To investigate whether the small city she lives in has a different average, a California high school student surveys 45 people she knows (her teachers, her parents, and their friends and co-workers) and finds the average commute time for this sample to be 24.33 minutes with a standard deviation of 9.53 minutes. The data are not too skewed. The null and alternative hypotheses of her study are: H0 : µ = 27.5 versus Ha : µ 6= 27.5
Required:
a. Identify the observational units for this study.
b. Identify the variable of interest and state whether it is categorical or quantitative.
c. Identify (in words and using an appropriate symbol) the parameter of interest
d. Use the 2SD approach to find a 95% confidence interval for the parameter.
e. Interpret the interval from part d. in context.

Step-by-step explanation:
1 km is 1000 m, so 4 km = 4000 m.
Zoe walks 4000 +600 = 4600 m.
Elijah runs 3(4600 m) = 13,800 m.
Anthony rides 700 m farther, so rides ...
13,800 m +700 m = 14,500 m
Anthony rides 14,500 meters.

Answers
Answer:
y = -3π/2 x + π
Step-by-step explanation:
sin(xy) = ½
The slope of the tangent line is dy/dx. Take the derivative of both sides with respect to x. You'll need to use chain rule and product rule.
cos(xy) (x dy/dx + y) = 0
x dy/dx + y = 0
x dy/dx = -y
dy/dx = -y/x
At x = ⅓ and y = π/2:
dy/dx = -(π/2) / ⅓
dy/dx = -3π/2
Using point-slope form of a line:
y − π/2 = -3π/2 (x − ⅓)
Simplifying to slope-intercept form:
y − π/2 = -3π/2 x + π/2
y = -3π/2 x + π

Answer and Step-by-step explanation: The differential equation described above is an Ordinary Differential Equation, because it has a definite set of variables: x and y.
It is of Second Order, since the highest derivative is of order 2: [tex]\frac{d^{2}y }{dx^{2} }[/tex]
The differential equation is written as derivative of a function y in terms of x, which means: Independent Variable is X and Dependent Variable is Y.
As it is an ODE, the equation is Nonlinear, because y'' or [tex]\frac{d^{2}y }{dx^{2} }[/tex] is multiplied by a variable.

Answer:
27/6, 4 3/6, or simplified version 4 1/2
Step-by-step explanation:
Always convert the mixed numbers into an improper fraction before you solve, this makes it easier to solve.
2 4/6 = 16/6
1 5/6 = 11/6
3 4/6 = 22/6
Now we solve. Remember, you do NOT add the denominator, leave it as 6 not 12. You only add the numerator.
16/6 + 11/6 = 27/6, 4 3/6 or simplified as 4 1/2
22/6 + 5/6 = The same as above.

A researcher gathers data on the length of essays (number of lines) and the SAT scores received for a sample of students enrolled at his university. Based on his regression output, the 95% confidence interval for the slope of the regression equation is (-0.88, 1.34). At α = 0.05, we can say:
a. the relationship between length of essays and SAT scores is significant and negative.
b. the slope of the regression equation is significantly different from zero.
c. the slope of the regression equation is not significantly different from zero.
d. the correlation between length of essays and SAT score is significant.
Answers
Answer
d. the correlation between length of essays and SAT score is significant.
Step-by-step explanation:
According to the case information, we know that the slope of the regression equation is -0.88 to 1.34, so our hypothesis is that the slope coefficient is 0, we deduce that taking into account the confidence interval the value is included by therefore the correct answer is D, which allows us to affirm that the correlation between the duration of the tests and the SAT score is significant

sin ^-1 ( sin A) = sin ^-1 (2/6)
A =19.47122063
