Answer:

The area (probability) is: 0.6864.

Step-by-step explanation:

According to the statement, we are in front of a normal distribution with the following parameters:

µ (mean) = 0

σ (Standard deviation) = 1.

Then we need to find the area of the shaded region, which is the area between the points -1.21 < z < 0.84.

And the area (probability) is: 0.6864.

Please helppp why is he right or wrong!!
bagirrra123 [75]

Answer:

We cannot agree with Andre because x = 3.

Step-by-step explanation:

Assuming the diagram is a weighing scale which can also be represented as an equation having two sides that is balanced. We can express the situation as follows using equation:

x + 2 = 5

Solve for x

x + 2 - 2 = 5 - 2 (subtraction property of equality)

x = 3

If you plug in the value of x on the diagram given, the scale becomes balance on each side.

Therefore, x = 3. Andre is wrong and we cannot agree with Andre.

Renee is hiking a trail that is 9¾ miles long. Renee hiked for 4¼ miles. After resting, Renee then hiked for 3½ miles. How many
Inessa [10]

Renee needs to hike 2 miles  to finish the hiking trail

The first step is to add the both miles

She hiked for 4 1/4 miles= 17/4

After resting she then hiked for another 3 1/2 miles= 7/2

17/4 + 7/2

= 31/4

The hiking trail is 9 3/4

To find the number of miles let to finish the trail, let's subtract 31/4 from 9 3/4

39/4 -31/4

= 8/4

= 2

Hence Renee needs to hike for 2 miles to finish the hiking trail
