Answer:

-0.67

Step-by-step explanation:

Given that :

Population mean, μ = 4.7

Sample size, n = 68

Sample mean, M = 4.3

Sample standard deviation, s = 0.6

The effect size, d can be obtained using the relation :

d = (M - μ) / s

d = (4.3 - 4.7) / 0.6

d = - 0.4 / 0.6

d = - 0.66666

d = - 0.67

Hence, effect size associated with a single-sample t test is - 0.67

If f(x)=5x what is f square -1 (x)?

Gnom [1K]

Answer:

$\frac{x}{5}$

Step-by-step explanation:

$f {}^{ - 1} (x)$

means inverse.

Find the inverse of the function.

$f(x) = 5x$

Replace y with and vice versa.

$x = {5y}$

Solve for y

$\frac{x}{5} = y$

The inverse function is

$\frac{x}{5}$

Travka [436]

Answer:

$1,175.34

Step-by-step explanation:

To solve for the total amount after 7 years. We need to use the formula:

$A = P(1+\dfrac{r}{n})^{nt}$

Let's first break down all the variables that we have.

P = 480

r = 13% or 0.13

n = 4 (Quarterly)

t = 7 years

Now we simply substitute the values into the formula.

$A = P(1+\dfrac{r}{n})^{nt}$

$A = 480(1+\dfrac{0.13}{4})^{4(7)}$

$A = 480(1+\dfrac{0.13}{4})^{28}$

$A = 480(1+0.0325)^{28}$

$A = 480(1.0325)^{28}$

$A = 480(2.45)$

$A = $1,175.34$

The account will have $1,175.34 after the 7 year period.
