Answer:

−

3v-2=1

3v−2=1

Solve

Add

to both sides of the equation

−

3v-2=1

3v−2=1

−

3v-2+{\color{#c92786}{2}}=1+{\color{#c92786}{2}}

3v−2+2=1+2

Simplify

Add the numbers

3v=3

Divide both sides of the equation by the same term

3v=3

\frac{3v}{{\color{#c92786}{3}}}=\frac{3}{{\color{#c92786}{3}}}

33v=33

Simplify

Determine the future value of a $25000 investment at an annual rate of 4.85% compounded quarterly for 6 years.

Nutka1998 [239]

= $ 32,275.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4.85%/100 = 0.0485 per year,
putting time into years for simplicity,
24 quarters ÷ 4 quarters/year = 6 years,
then, solving our equation

A = 25000(1 + (0.0485 × 6)) = 32275
A = $ 32,275.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 25,000.00
at a rate of 4.85% per year
for 6 years (24 quarters) is $ 32,275.00.

From 1995 - 2008 in the US 648 people were struck by lightening. 531 of them were men. You want to see if this observation diffe

Gre4nikov [31]

Answer:

Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis

Step-by-step explanation:

Sample proportion = p= 531/648 = 0.8194

This is the proportion of men that were hit by lightening

Null hypothesis: H0: p = 0.5

Alternate hypothesis: H1: p ≠ 0.5

Test statistics z = 0.8194-0.5/(√0.5x0.5/648)

= 0.8194-0.5/√0.0003858

= 0.3194/0.019642

= 16.26

Since the z > 1.96 (at 5% significance) we reject the null hypothesis.

Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.

I need to change the subject to x

tiny-mole [99]

(x - 4y) / w = 9

Multiply both sides by w

x - 4y = 9w

Add 4y to both sides

x = 9w + 4y
