8 0

Answer:

The probability that the answer is an even number is 50%.

Step-by-step explanation:

There are 8 terms: 8, 9, 10, 11, 12, 13, 14, 15. Even numbers: 8, 10, 12, 14. So, 4 out of the 8 terms are even, which is equivalent to 50%.

What is the y-intercept of a line that has a slope of 3 and passes through point (-1, -7)?

Ivanshal [37]

Answer:

-4

Step-by-step explanation:

We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:

y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1

y - (-7) = 3(x-(-1))

y+7 = 3(x+1)

y+7 = 3x +3

Change to slope-intercept form:

y = 3x + 3 - 7

y = 3x = -4

the y intercept is -4

Answer:

$m\angle D=64^{\circ}$

Step-by-step explanation:

Given

$\triangle ABE\sim \triangle TCD$

Similar triangles have conruent corresponding angles, so

$m\angle A=m\angle T=61^{\circ}\\ \\m\angle B=m\angle C=55^{\circ}\\ \\m\angle E=m\angle D$

The sum of the measures of all interior angles of the triangle is always equal to 180°, so

$m\angle T+m\angle C+m\angle D=180^{\circ}\\ \\61^{\circ}+55^{\circ}+m\angle D=180^{\circ}\\ \\m\angle D=180^{\circ}-61^{\circ}-55^{\circ}=64^{\circ}$
