Answer:
0.2601
Step-by-step explanation:
There are 19C16 = 969 ways for Lester to choose 16 of the 19 objects.
There are 12C11 = 12 ways to choose 11 vases, and 7C5 = 21 ways to choose a non-vase, for a total of (12)(21) = 252 ways to choose exactly 11 vases in 16 objects.
So, the probability of interest is ...
252/969 ≈ 0.2601
_____
nCk = n!/(k!(n-k)!) ... the number of ways to choose k objects from n
Answer:
A. 0.083%
Step-by-step explanation:
Total population=60,000
Total infected=600
Percentage of total infected=600/60,000×100
=0.01×100
=1% of the total population
50 people died out of total infected
Percentage of death of total infected=50/600×100
=8.33%
Total death from all causes=110
Percentage of total death from all causes to the total population=110/60,000×100
=0.1833%
Proportionate mortality rate(PMR) of dengue in the population can be calculated as:
Percentage of death from total infected to the total population
=50/60,000×100
=0.0833%
Approximately 0.083%
Given:
Figure of similar triangles.
To find:
The value of x and the measure of NR.
Solution:
In triangle RST and RMN,
(Vertically opposite angles)
(Alternate interior angles)
(By AA property of similarity)
We know that, corresponding sides of similar triangles are proportional.
On further simplification, we get
The value of x is 7.
Now,
Therefore, the value of x is 7 and the measure of NR is 12 units.
Answer:
y = (x-15)/-8
Step-by-step explanation:
When solving for an inverse function, swap x and y without bringing the x coefficient with it, just simply swap the variables. Then, solve for y, and that's it.
y = -8x + 15
x = -8y + 15
x-15 = -8y
(x-15)/-8 = y
I believe the correct answer is:
b = c - 1; b = c - 7
