Step-by-step explanation:

5.) 0.37 - 0.236 = 0.134

6.) 9.71 - 3.56 = 6.15

Triangle ABC has coordinates A(-3,3), B(3,2) and C(-1,-4). If the triangle is reflected over the y-axis, what are the coordinate

kupik [55]

Answer:

The coordinates of the image triangle are A'(3,3), B'(-3,2), C'(1,-4).

Step-by-step explanation:

Given Triangle ABC has coordinates A(-3,3), B(3,2) and C(-1,-4).

If the triangle is reflected over the y-axis, we can use the following rule:-

P_y-axis (x, y) → P'(-x, y)

Using the above rule, we can find the coordinates of the image triangle as follows:-

A (-3, 3) → A' (3, 3)

B (3, 2) → B' (-3, 2)

C (-1, -4) → C' (1, -4)

Hence, the coordinates of the image triangle are A'(3,3), B'(-3,2), C'(1,-4).

When Isaac commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 44 minutes and a s

mario62 [17]

Answer:

[34,54]

Step-by-step explanation:

-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.

Where:

68% is the first standard deviation
95% is the second standard deviation about the mean
99.7% is the 3rd standard deviation about the mean.

-Therefore. the middle 95% interval is calculated as:

$CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]$

Hence, the interval is [34,54]
