Line segment segment CD has a slope of negative start fraction two over three end fraction and contains point C(−3, −6). What is
Elanso [62]
For perpendicular lines, the slopes are negative reciprocals of one another. Therefore, the slope of QC = 3/2

Using this into the formula of slope:
3/2 = (y + 6) / (-1 + 3)
y = -9

If the slope of CD is 2/3, then y works out to be -3.

kogti [31]

Answer:

Simplifying

12t + -8t = 0

Solving

4t = 0

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Divide each side by '4'.

t = 0

Simplifying

azamat

Answer:

Option C

Step-by-step explanation:

Given that for a  random sample of 20 houses selected from a city showed that the mean size of these houses is 1880 square feet with a standard deviation of 320 square feet.

X, the sizes of houses is Normal

Hence sample mean will be normal with

Mean = 1880

and std dev = \frac{320}{\sqrt{20} } \\=71.5542

For 90% confidence interval critical value for t with degree of freedom 19 is

1.328

Confidence interval upper bound

= mean + margin of error

= 1880+1.328*71.55\\=1975

Option C is right
