Hey!

---------------------------------------------------

Question #1:

b + 0.6 = -1

b + 0.6 - 0.6 = -1 - 0.6

b = -1.6

Answer:

$\boxed{ \bf b~=~-1.6}$

---------------------------------------------------

Question #2:

y - 0.6 = -1.8

y + (-0.6) + 0.6 = 1.8 + 0.6

y = -1.2

Answer:

$\boxed{ \bf y~=~-1.2}$

---------------------------------------------------

Question #3:

n + 11.5 = -29

n + 11.5 - 11.5 = -29 - 11.5

n = -40.5

Answer:

$\boxed{ \bf n~=~-40.5}$

---------------------------------------------------

Question #4:

e - 14.4 = -20.8

e - 14.4 + 14.4 = -20.8 + 14.4

e = -6.4

Answer:

$\boxed{ \bf e~=~-6.4}$

If f(x)=3x + 2, find f(f^-1(14)).

dimaraw [331]

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

Can someone assist me with this?

Mnenie [13.5K]

Answer:

29: 7

Step-by-step explanation:

$\frac{8}{3x - y} = \frac{5}{x + 3y}$

Cross multiply:

$8(x + 3y) = 5(3x - y)$

Expand bracket:

$8x + 24y = 15x - 5y$

Bring x terms to 1 side, y terms to the other:

$15x - 8x = 24y + 5y$

Simplify:

$7x = 29y$

Divide by 7 on both sides:

$x = \frac{29}{7} y$

Divide both sides by y:

$\frac{x}{y} = \frac{29}{7}$

∴ The ratio of x to y is 29:7.

A jar contains 5 black and 9 white marbles priscilla draws a marble from the jar what is the probability that she drew a black m

Vanyuwa [196]

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%.

4. (8 pts) A random sample of 78 students were interviewed and 59 said they would vote for a democrat in the 2008 election.

Naddik [55]

a point estimate for p is 75.6 %

To calculate point estimate

point estimate = $\frac{59}{78} \times 100$ = 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.
