Answer:
0.167772
Step-by-step explanation:
Given that eight persons were asked to cooperate in an experiment. Five very small bowls of flake cereals were placed in front of a person
Since each one makes only guess probability for correct guess is
=
Each person is independent of the other
Hence X no of persons out of eight persons selected to guess correctly is binomial with n =8 and p = 0.2
Required probability
=the probability that none of the eight guessed correctly
=
Answer:
The scale factor is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
so
therefore
The scale factor is 9/7
Find the value of x
The value of x is equal to
Answer:
E
Step-by-step explanation:
Let's say "s" represents the number of steps you still need to take to achieve your goal of at least 12,100 steps. You've already walked 5204 steps, and if we add this to s, we should get a total of <em>at least</em> 12,100 steps:
s + 5204
The words "at least" means that we need to use ≥, so:
s + 5204 ≥ 12,100
The answer is E.
If we were to solve this inequality:
s + 5204 ≥ 12,100
s ≥ 6896
In other words, you still have to take at least 6896 more steps.
Answer:
We know that the angles of a triangle always add up to 180 degrees, and we also know that this triangle is congruent because it has the two dashes on the side of the triangle. We also know that x is 90 degrees but this is not drawn to scale but we can just assume it is 90 degrees.
We can tackle the triangle on the right first subtracting 47 and 90 from 180 which will give us the angle y as angle DAC is congruent to angle BAC.
180-47-90=43.
We also know that angle x is 90 degrees already or at least we assume so but to further prove our point we know that angle BCA is congruent to angle CBA which makes angle CBA 47 degrees, so subtracting 43 and 47 from 180 we have 90 degrees.
Therefore y is 43 degrees and x is 90 degrees.
it's kinda confusing ngl
*assuming that x is a right angle
