Step-by-step explanation:
When adults with smartphones are randomly selected, 61% use them in meetings or classes, then
- the probability of using the smartphone is
- the probability of not using the smartphone is
If 8 adult smartphone users are randomly selected, the probability that exactly 3 of them use their smartphones in meetings or classes can be calculated using binomial distribution as
Note that
then the probabilty is
The shape formed, when a prism with a heart-shaped base is sliced parallel to the base, will be congruent to its base. Hence, it will also be <u>heart-shaped</u>.
A prism is a polyhedron made up of n parallelogram faces that connect the n-sided polygon base, the second base, which is a translated duplicate of the first base, and the n faces. The bases are translated into all cross-sections that are parallel to them.
In the question, we are informed that a prism with a heart-shaped base is sliced parallel to the base.
We are asked what shape is formed.
From the above discussion, we know that the bases are translated into all cross-sections that are parallel to them, that is, all cross-sections parallel to the base, will be congruent to the base.
Thus, the shape formed, when a prism with a heart-shaped base is sliced parallel to the base, will be congruent to its base. Hence, it will also be <u>heart-shaped</u>.

Answer:
it will be c, x=8.5
Step-by-step explanation:
-18+4x=-4x+50
4x+4x=18+50
8x=68
x=8.5
The answer is 80’, because is the corresponding angle of 1, so it must be the same answer as 1 angle.
Answer:
This can't be factored right now! But if it is 2z^2+12z+10=0 than it will be factored like this:
2*(z+5)(z+1)
Step-by-step explanation:
2*(z^2+6z+5)=0
2*(z+5)(z+1)
