Through: (4, -3), perp. to y=-2x + 1
larisa86 [58]

Step-by-step explanation:

y = -2x + 1. => Slope = -2

Then the perpendicular line will have a slope of -1/(-2) = 0.5.

We have y = 0.5x + c.

When x = 4, y = -3.

=> (-3) = 0.5(4) + c, c = -5.

Hence the answer is y = 0.5x - 5. (C)

The 2010 General Social Survey reported a sample where about 48% of US residents thought marijuana should be made legal. If we w
Sati [7]

Answer:

The sample size is  n  = 600

Step-by-step explanation:

From the question we are told that

    The  sample proportion is  \r  p = 0.48

     The  margin of error is  MOE  =  0.04

Given that the confidence level is 95%  the level of significance is mathematically represented as

        \alpha  =  100 - 95

        \alpha  =  5 \%

        \alpha  =  0.05

Next  we obtain the critical value of  \frac{\alpha }{2} from the normal distribution table , the values is

                   Z_{\frac{\alpha }{2}  } =  1.96

The reason we are obtaining critical value of    \frac{\alpha }{2} instead of    \alpha is because  

\alpha represents the area under the normal curve where the confidence level interval (  1-\alpha) did not cover which include both the left and right tail while  

\frac{\alpha }{2} is just the area of one tail which what we required to calculate the margin of error

Generally the margin of error is mathematically represented as

      MOE  =  Z_{\frac{\alpha }{2} } *  \sqrt{ \frac{\r p(1-  \r p )}{n} }

substituting values

          0.04= 1.96*  \sqrt{ \frac{0.48(1-  0.48 )}{n} }

         0.02041 = \sqrt{ \frac{0.48(52 )}{n} }

         0.02041 = \sqrt{ \frac{ 0.2496}{n} }

          0.02041^2  = \frac{ 0.2496}{n}

           0.0004166 = \frac{ 0.2496}{n}

=>       n  = 600

Sindi borrowed an amount of money from his
PolarNik [594]

The present value of the loan is R576923.

<h3>What is compound interest ?</h3>

Compound interest is giving the current instalment in terms of the total previous amount.

The formula is given by

A = P(1 + r/100)ⁿ.

Where,

A = Amount, P = Principle, r = rate of interest, n = Time in years.

In case the compound if interest is given every two months that is 6 instalments each year the above given formula will be

A = P{ 1 + (r/6)/100 }⁶ⁿ.

According to the given question

Rate(r) = 7.5%

Time(n) = 6 years

The loan will be paid back in 6 years every second month and it is compounded.

∴ No. of instalments = (12 × 6)/2

= 36.

Now each instalments is of R25000

So, The total amount she has to pay back to his father is

= (25000 × 36)

= R900000.

We know compounding every two months is

A = P(1 + r/100)ⁿ

900000 = P{ 1 + (7.6/6)/100 }³⁶

900000 = P{ 1 + 1.25/100 } ³⁶

900000 = P(1.0125)³⁶

900000 = 1.56P

∴ P = 576923.
