Answer:

Simple interest = $ 3,484.00

Step-by-step explanation:

I= P×R×T ÷ 100

The rate is 6 1/2 and I will use the decimal form 6.5,to change that to a whole number we simply move the decimal point one place behind.

Since we moved the decimal point in the numerator we need to do the same for the denominator.Therefore 100 becomes 1000.

<u>13400 × 65 × 4</u> = $ 3,484.00

1000

What is the simplified form of the expressions? a. −6a2b−1 b. 5/y−3

joja [24]

Given:

The expressions are

$-6a^2b^{-1}$

$\dfrac{5}{y^{-3}}$

To find:

The simplified form of each expression.

Solution:

We have,

$-6a^2b^{-1}$

$=-6a^2(\dfrac{1}{b})$ $[\because x^{-n}=\dfrac{1}{x^n}]$

$=-\dfrac{6a^2}{b}$

Therefore, the simplified form of $-6a^2b^{-1}$ is $-\dfrac{6a^2}{b}$ .

We have,

$\dfrac{5}{y^{-3}}$

$=\dfrac{5}{\dfrac{1}{y^3}}$ $[\because x^{-n}=\dfrac{1}{x^n}]$

$=5\times \dfrac{y^3}{1}$

$=5y^3$

Therefore, the simplified form of $\dfrac{5}{y^{-3}}$ is $5y^3$ .

In a recent study, your town's chamber of commerce found that 73% of town residents believed that local businesses overcharged f

Dominik [7]

The Confidence interval for 95% who believes that the local businesses overcharge = (0.7026, 0.7574)

<h3>What is meant by confidence interval?</h3>

The range of values we see in our sample and hope to identify the value that most closely represents the population are referred to as a confidence interval.

<h3>According to the given information:</h3>

Sample size n = 1000

73% of town residents believed that local businesses overcharged for their products over 1000 resident.

= (1000/100) x 73

= 730

Sample proportion p = 730/1000

= .73

q = 1-p = 0.23

Std error of proportion = √(pq/n)

= √((.73*0.27)/1000)

= 0.0140

95% Z critical value = 1.96

Margin of error = 1.96*0.0140

= 0.0274

Confidence interval = sample proportion ±margin of error

(0.7026, 0.7574)

Can someone please answer my trigonometry problem? I've been trying to get answers all day for something so minimal.

Fantom [35]

Answer:

∠B ≈ 30.0°

Step-by-step explanation:

The law of sines can be used to solve a triangle when two sides and an angle opposite one of them are given.

sin(B)/b = sin(C)/c

sin(B) = (b/c)sin(C) . . . . solve for sin(B)

sin(B) = (14/28)sin(91°) ≈ 0.49992385

The angle is found using the inverse sine function:

B = arcsin(0.49992384) ≈ 29.99496°

Rounded to tenths, the angle is ...

m∠B ≈ 30.0°

_____

<em>Additional comments</em>

Many triangle solver apps and web sites are available if all you want is an answer.

When using your calculator, be sure the angle mode is set to "degrees."

The Law of Sines can also be used to solve a triangle when two angles and one side are known.

I need help because I don’t know what they are asking

Mashutka [201]

Answer:

16x -2

Step-by-step explanation:

You know how to compute the perimeter of a rectangle of length L and width W:

P = 2(L+W)

Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.

P = 2((5x-2) +(3x+1))

P = 2(8x -1)

P = 16x -2 . . . the perimeter of the rectangle
