Answer:
0.9586
Step-by-step explanation:
From the information given:
7 children out of every 1000 children suffer from DIPG
A screening test designed contains 98% sensitivity & 84% specificity.
Now, from above:
The probability that the children have DIPG is:
= (0.98 × 0.007) + 0.16( 1 - 0.007)
= 0.16574
So, the probability of not having DIPG now is:
= 0.9586
Answer:
1) b, c, d
2) d
3) a, c, d
Step-by-step explanation:
Just find the number that can divide by the whole. Say the question was
A pet shop have 20 pets. The same amount of pets are in each room. How many rroms could there be?
If there were 4 rooms, 5 pets would be in each. 20÷4=5. 4 goes into 20 so 4 could be an answer.
If there were 3 rooms, 6 rooms would have 3 pets and 2 would be left over. So it wouldn't work. You just need to find the number that goes into the whole with no remainder.
Answer:
k= -2
Step-by-step explanation:
you are dividing the x by -2 each time
Answer:
<h3> D){?}
x = 7</h3>
Step-by-step explanation:
x + 3•(+1) = 2•x + 4•(-1)
x + 3 = 2x - 4
-3 -3
x = 2x - 7
-2x -2x
- x = -7
÷(-1) ÷(-1)
x = 7
It is given in the question that cost of pork is $7.99/kg.
It means cost of 1 kg pork is $7.99.
Cost of 2 kg of pork is
And cost of 3 kg of pork is
Therefore cost of 3.5 kg of pork is
