30 x 10 = 300

Answer:

x=5°

∠JIK=110°

Step-by-step explanation: From question,

20x-10+8x-20=140-6x

28x-30=140-6x

34x=170

x=170/34

x=5°

Eq. in ∠JIK,

140-30

=110°

Complete Question

It is found that on average, 9% of the population recycles its garbage. Under this assumption, if a random sample of 120 households in Iowa City is taken, would you be surprised to find that fewer than 3% of households in the sample recycle their garbage? Use the fact that p-hat has an approximately normal distribution.

Group of answer choices

A I would not be surprised because there are lots of lazy students in Iowa City.

B I would not be surprised because 3% is not that far away from 9%.

C I would be surprised because Iowa City is a very clean community which means lots of people recycle their garbage.

D I would be surprised because if the 9% average is true, the chance of a sample proportion being less than 3% is very small (only 1%). Who cares? It's only garbage!

Answer:

The correct option is D

Step-by-step explanation:

From the question we are told that

    The sample size is  n  = 120

    The  mean of the proportion is  p =  0.09

Generally the standard deviation is mathematically represented as

      [tex]\sigma  =  \sqrt{\frac{p(1-p)}{n} }[/tex]

=>   [tex]\sigma  =  \sqrt{\frac{0.09(1-0.09)}{120 } }[/tex]

=>   [tex]\sigma  = 0.02612[/tex]

Generally the chance that fewer than 3%   of households in the sample recycle their garbage is mathematically represented as

    [tex]P(X < 0.03) =  P( \frac{X - p}{\sigma}  <  \frac{0.03 -0.09}{0.02612} )[/tex]

    [tex]P(X < 0.03) =  P( Z  < -2.297 )[/tex]

From the z-table  

     [tex]P( Z  < -2.297 ) = 0.01[/tex]

=> [tex]P(X < 0.03) = 0.01/tex]

=>   [tex]P(X < 0.03) = 1\% /tex]

Answer:

$373.12

Step-by-step explanation:

You want to set this up with the equation for compound interest which is [tex]A=P(1+\frac{r}{n})}^{nt}[/tex]. A stands for amount, P stands for principle which in this case is 350, r is rate which for this one is .065, ad n is the amount of times compounded per year, and since it is compounded semi annually you do 2 for 2 times a year. Your equation based on this information should look like this:

[tex]A=350(1+\frac{.065}{2})}^{(2)(1)}[/tex]

After working this out you get A = 373.12

$373.12

Answer:

Step-by-step explanation:

Both angles added together = 180 degrees. They both have a straight line as their base.

So let <ABC = x

Then <CBD = 3x      Add the two angles

x + 3x = 180              Combine

4x = 180                    Divide by 4

4x/4 = 180/4

x = 45

So 3x = 3*45 = 135

Answer:

We have to find the LCM(least common multiple) of the two numbers.

24 is the LCM, because;

Multiples of 8 are -

8 x 1 = 8

8 x 2 = 16

8 x 3 = 24

Multiples of 12 are -

1 x 12 = 12

2 x 12 = 24

24 is their least common multiple.

[tex]\\ \sf\longmapsto y=2x[/tex]

In slope intercept form

Answer:

Step-by-step explanation:

Line passes through origin (0, 0) so y-intercept is zero: b=0

At x=2, y=4 so slope is 4/2=2: m=2

Answer: $827

Step-by-step explanation:

Given that :

Cash down payment = 5880

Payment at end of first year = 5880

Payment at end of second year = 5880

Interest rate = 5% = 0.05 compounded yearly

Let purchase amount = y

Amount left after cash down = amount on which interest is paid = y - 5880

Interest at end of first year :

(y - 5880) * 0.05 = 0.05y - 294

Amount to pay plus interest :

Amount left after cash down payment - amount paid at end of first year + interest

y - 5880 - 5880 + 0.05y - 294

y - 12054 + 0.05y

= 1.05y - 12054

2nd year interest :

(1.05y - 12054) * 0.05

= 0.0525y - 602.7

Amount left + interest = 2nd year payment

(1.05y - 12054) + (0.0525y - 602.7) = 5880

1.1025y - 12656.7 = 5880

1.1025y = 5880 + 12656.7

1.1025y = 18536.7

y = 18536.7 / 1.1025

y = 16813.33

Hence,

Sales price of washing machine = 16813.33

Total amount paid = (5880 + 5880 + 5880) = 17640

Interest paid = $(17640 - 16813.33) = $826.67

= $827

The total interest paid by him in this scheme, if the rate of interest is 5% compounded yearly is INR 826.67

Given:

Down payment = INR 5880

Payment at end of first year = INR 5880 (same as down payment)

Payment at end of second year = INR 5880 (same as down payment)

Interest rate = 5%

= 5/100

= 0.05 compounded yearly

Amount of purchase = x

Amount remaining after down payment

= x - 5880

Interest at end of first year :

(x - 5880) * 0.05(5,880)

= 0.05x - 294

Amount to pay plus interest = Amount remaining after down payment - amount paid at end of first year + interest

= x - 5880 - 5880 + 0.05x - 294

= x - 12,054 + 0.05x

= 1.05x - 12,054

2nd year interest :

(1.05x - 12054) * 0.05

= 0.0525x - 602.7

Amount left + interest = 2nd year payment

(1.05x - 12054) + (0.0525x - 602.7) = 5880

1.1025x - 12656.7 = 5880

1.1025x = 5880 + 12656.7

1.1025x = 18536.7

divide both sides by 1.1025

x = 18536.7 / 1.1025

x = 16,813.33

Therefore, The cost of washing machine b is INR 16,813.33

Total amount paid = (5880 + 5880 + 5880) = INR 17,640

Amount of Interest paid = (17640 - 16813.33)

= INR 826.67

Answer:

-0.71

Step-by-step explanation:

Generally, a value of r greater than 0.7 is considered a strong correlation. Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation.

The r-value that represents the strongest correlation is -0.71.

Any of the many metrics used to describe the strength and direction of a linear relationship between two random variables is called a correlation coefficient.

So, r stands for the correlation coefficient.

Depending on the direction of the association, an r-value may be either negative or positive.

Yet, the link is greater the closer an r-value is to 1.

Here - 0.71 is closer to -1 then it is having a strongest correlation.
