Answer:
57 to 63
Step-by-step explanation:
A suitable probability tool can tell you the limits.
8% of scores will be below 56.95 ≈ 57
76% of scores will be above 63.24 ≈ 63
Scores between 57 and 63 will get a D grade.
Answer:
-1 ( 1/3*1/3*1/3*1/3)
Step-by-step explanation:
-(3)^-4
The exponent is only affecting what is inside the parentheses
-1 * (3) ^-4
We know that a^-b = 1/a^b
-1 * 1/3^4
-1/3^4
-1 ( 1/3*1/3*1/3*1/3)
The molar solubility of Ba₃(PO₄)₂ is its concentration of pure substance
The correct equation for the ksp is Ksp = 6x⁵
<h3>How to determine the
equation of ksp?</h3>
Start by writing the reaction for the solution of Barium phosphate
Ba₃(PO₄)₂ ⇌3Ba²⁺ +2PO₄³⁻
Next, we make an ICE chart
Let "x" be the molar solubility of Barium phosphate
Ba₃(PO₄)₂(s) ⇌3Ba²⁺ +2PO₄³⁻
I 0 0
C +3x +2x
E 3x³ 2x²
Lastly, we write the expression for the solubility product constant (Ksp)
This is represented as:
Ksp = [3Ba²⁺] × [2PO₄³⁻]²
Ksp = 3x³ × 2x²
Evaluate the product
Ksp = 6x⁵
Hence, the correct equation for the ksp is Ksp = 6x⁵

Answer:
2250 People
Step-by-step explanation:
P=Total population
P=2000(1+.04)^3years
P=2249.728
P=2250
three hundred twenty-six thousandths = .326
nine hundred twenty-four thousandths = .924
