The first choice because it’s easier than having to add a bunch of numbers so S=(9)(2)(4)
Discriminant is the value b^2 - 4*a*c
(-3)^2 - 4*2*1
9 - 8 = 1
Answer:
The solution to the given points can be defined as follows:
Step-by-step explanation:
In point a:
There is still a 2.3% chance which 15.1% of learners who also don't achieve a level by naturally-excluding specimens only will see if 15.9% is the population means value.
In point b:
Throughout the old system, 1352 learners must not read in classes, but 1284 should not write throughout academic performance throughout the new curriculum. A reduction, as well as the significance of such a decrease, would depend mostly on the cost of switching to the new initiative.
Answer:
option c, 70%
Step-by-step explanation:
80 total keychains
24 are blue
80 total keychain - 24 blue keychain = 56 non blue key chain
the probability of chooising one of these 56 keychain is
56 / 80 = 0.70
0.70 x 100% = 70%
OR
the probability of chooising a blue keychain is
24 / 80 = 0.30
1 - 0.30 = 0.70 (1 = the total amount)
Answer:
true
