Answer:
14.90 to 16.70 tons
Step-by-step explanation:
We are given;
Sample size; n = 49
Mean; x¯ = 15.8
Sample standard deviation; s = 3.85
At 90% Confidence interval, z = 1.645
Formula for confidence interval is;
CI = x¯ ± z(s/√n)
Thus;
CI = 15.8 ± 1.645(3.85/√49)
CI = 15.8 ± 0.90
CI = 14.90 to 16.70 tons
A + B = 75
A * B = 1134
A = 21 B = 54
Hello!
-3(x - 14) + 9x = 6x + 42
Distribute the coefficient of the parenthesis:
-3(x) - 3(-14) + 9x = 6x + 42
-3x + 42 + 9x = 6x + 42
Combine like terms:
6x + 42 = 6x + 42
Both sides of the equation are the same, therefore:
There are infinitely many solutions.

I think so this is the ans.
Answer:
3/32
Step-by-step explanation:
Labels from 1 to 8:
The probability that he gets a number less than 4 (1, 2, 3) is 3/8
The probability to get a multiple of 4 (4, 8) is 2/8 = 1/4
So
The probability that he gets a number less than 4 or a multiple of 4:
= 3/8 x 1/4
= 3/32
Answer
3/32
