Please help me with these I’m so confused (best answer = Brainliest)

For the box plot, plot the minimum and maximum on a line. then find the median of the data. divide the data into two groups and find the median of each and graph those, then draw the boxes. IQR is the third quartile minus the first. a quartile is a quartile regardless of size. both boxes are quartiles and both tails are too. hope that makes sense

Marsha uses 8.5 pints of white paint and blue paint to paint her bedroom walls. 2/5
Serjik [45]

Answer:

5.1 pints

Step-by-step explanation:

Theres 2 ways

First way:

We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.

Second way:

We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints

Hope this helped! I would appreciate a Brainliest if this helped you!

An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled usin
ioda
The height at time t is
h(t) = 144 - 16t²

When t = 0, then h = 144.
Therefore the height from the ground is 144 when the object is dropped.

When the object reaches the ground, h = 0.
Therefore
144 - 16t² = 0
t² = 144/16 = 9
t = 3 s

Answer:
The object reaches the ground in 3 seconds.
