Question #1:
b + 0.6 = -1
b + 0.6 - 0.6 = -1 - 0.6
b = -1.6
Answer:

---------------------------------------------------
Question #2:
y - 0.6 = -1.8
y + (-0.6) + 0.6 = 1.8 + 0.6
y = -1.2
Answer:

---------------------------------------------------
Question #3:
n + 11.5 = -29
n + 11.5 - 11.5 = -29 - 11.5
n = -40.5
Answer:

---------------------------------------------------
Question #4:
e - 14.4 = -20.8
e - 14.4 + 14.4 = -20.8 + 14.4
e = -6.4

Hope This Helped! Good Luck!
Answer:
f(x) = 3x + 2
x = 3f-1(x) + 2
x - 2 = 3f-1(x)
(x - 2)/3 = f-1(x)
(14 - 2)/3 = f-1(14)
12/3 = f-1(14)
4 = f-1(14)
f(f-1(14)) = f(4)
f(4) = 3(4) + 2
f(4) = 12 + 2
f(4) = 14
A function and its inverse are inverse operations, like addition and subtraction. They undo each other.
f(f-1(x) = x
Step-by-step explanation:
Answer:
29: 7
Step-by-step explanation:

<em>Cross</em><em> </em><em>multiply</em><em>:</em>

<em>Expand</em><em> </em><em>bracket</em><em>:</em>

<em>Bring</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>y</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>

<em>Simplify</em><em>:</em>
<em>
</em>
<em>Divide</em><em> </em><em>by</em><em> </em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>y</em><em>:</em>
<em>
</em>
∴ The ratio of x to y is 29:7.
The probability of the black marble will be 35.7% because 100/(9+5) is 7.14 and you multiply that by 5 to get 35.7%.
a point estimate for p is 75.6 %
To calculate point estimate
point estimate =
= 75.6%
<h3>
what is point estimate?</h3>
- In statistics, point estimating uses sample data to determine a single value that will serve as the "best guess" or "best estimate" of an unidentified population parameter.
- It is called a point estimate because it identifies a point in some parameter space (for example, the population mean). More precisely, it is the process of applying a point estimator to the data in order to produce a point estimate.
- Point estimation can be compared with interval estimation, where the interval estimates are typically either credible intervals or confidence intervals depending on whether frequentist or Bayesian inference is being used. A point estimator can be compared to a set estimator more generically.
