Answer:

Step-by-step explanation:

Equation:

$\frac{x}{-2}+\frac{y}{10}=1\\\\\frac{x*5}{-2*5}+\frac{y}{10}=1\\\\\frac{-5x}{10}+\frac{y}{10}=1\\\\-5x+y=10\\\\y=5x+10$

Brayden tosses a coin 500 times. Of those 500 times, he observes heads a total of 416 times. Calculations show that the probabil

Answer: The probability of this ocurring by chance is less than 0.01.

The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.

Step-by-step explanation:

Since we have given that

Number of times a coin tossed = 500

Number of times head occurs = 416

So, our Z-score would be

$Z_\alpha =\dfrac{416}{500}=0.832$

So, At significance level of 0.01, p-value of Z-score is .202704.

and p-value < 0.01, i.e. 0.202704<0.832.

Hence, the probability of this ocurring by chance is less than 0.01.

The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.

What is the focus of the parabola given by the equation y = x2 − 2x − 3?

erica [24]

What is the focus of the parabola given by the equation y = x2 − 2x − 3?
y = x2 − 2x − 3
y = x2 − 2x − 3 -1 +1y = (x - 1)^2 - 4 h = 1 and k = - 4 and a = 1

Vertex (a, k) so it is (1,-4)

Now focus is
(1, -4 + 1/4) = (1,-3 3/4)
or
(1,-3.75)

8 angles are formed by a transversal that intersects two parallel lines. Angles Alpha and Epsilon are Consecutive Exterior Angle

Afina-wow [57]

Answer:

113 degrees

Step-by-step explanation:

Since, Angles Alpha and Epsilon are Consecutive Exterior Angles.

$\therefore m\angle \alpha + m\angle \epsilon = 180 \degree \\ \\ \therefore m\angle \alpha + 67 \degree= 180 \degree \\ \\ \therefore m\angle \alpha = 180 \degree -67 \degree \\ \\ \therefore m\angle \alpha = 113 \degree$
