Answer:
there you goooo- kitkat
Step-by-step explanation:
For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.
If the number of trials is changed, the experimental probability also changes.
If the number of trials is changed, the predicted number of outcomes also changes.
If the number of trials is changed, the number of experimental outcomes also changes.
Answer:
at 5% interest, she invested $8,000
at 6% interest, she invested $2,000
Step-by-step explanation:
Let the invested amount at 5% interest = x
Let the invested amount at 6% interest = y
x = 4y - - - - (1) (A woman invested 4 times as much as 5% as she did at 6%)
5% of x = 0.05x
6% of y = 0.06y
0.05x + 0.06y = 520 - - - - (2) (The total amount of interest she earns is $520)
putting the value of x gotten in equation (1) into eqn (2):
0.05x + 0.06y = 520
where x = 4y
∴ 0.05(4y) + 0.06y = 520
0.2y + 0.06y = 520
0.26y = 520
y = 520 ÷ 0.26
y = $2000
from eqn (1)
x = 4y
since y = 2000
x = 4 × 2000
x = $8000
Answer:
A = 
Step-by-step explanation:
given,
Matrix =
A = 
determinant of matrix
|A| = a×a - (a-4)(a+4)
|A| = a² - a² +16
|A| = 16
inverse of the matrix
to calculate inverse of two matrix interchange the term a₁₁ with a₂₂ and multiply the -ve with a₁₂ and a₂₁
the inverse is
A = 
Answer: 32
Step-by-step explanation:
The output is 1/3 of the input +2
Solve for b:
5 a (b - c) = d
Divide both sides by 5 a:
b - c = d/(5 a)
Add c to both sides:
Answer: b = c + d/(5 a)
