<em>Advantages of using a credit card:</em>

You can buy things without actually having the cash.

You can report the loss of your card to the card issuer, thereby minimizing any financial loss.

It helps you establish credit or build credit history.

Some credit cards offer rewards.  


<em>Advantages of using cash: </em>

You see exactly what you are spending.

You are less likely to indulge in impulse buying.

You don’t have to pay any interest.

Money: You won't overspend. You won't have to worry about fees.

3. The Food Marketing Institute shows that 17% of households spend more than $100 per week on groceries. Assume the population p
damaskus [11]

Answer:

A)sample proportion = 0.17,  the sampling distribution of p can be calculated/approximated with normal distribution of sample proportion = 0.17 and standard error/deviation = 0.013281

B) 0.869

C)0.9668

Step-by-step explanation:

A) p ( proportion of population that spends more than $100 per week) = 0.17

sample size (n)= 800

the sample proportion of p = 0.17

standard error of p = \sqrt{\frac{p(1-p)}{n} } = 0.013281

the sampling distribution of p can be calculated/approximated with

normal distribution of sample proportion = 0.17 and standard error/deviation = 0.013281

B) probability that the sample proportion will be +-0.02 of the population proportion

= p (0.17 - 0.02 ≤ P ≤ 0.17 + 0.02 ) = p( 0.15 ≤ P ≤ 0.19)

z value corresponding to P

Z = \frac{P - p}{standard deviation}

at P = 0.15

Z =  (0.15 - 0.17) / 0.013281 = = -1.51

at P = 0.19

z = ( 0.19 - 0.17) / 0.013281 = 1.51

therefore the required probability will be

p( -1.5 ≤ z ≤ 1.5 ) = p(z ≤ 1.51 ) - p(z ≤ -1.51 )

                           = 0.9345 - 0.0655 = 0.869

C) for a sample (n ) = 1600

standard deviation/ error = 0.009391 (applying the equation for calculating standard error as seen in part A above)

therefore the required probability after applying

z = \frac{P-p}{standard deviation} at p = 0.15 and p = 0.19

p ( -2.13 ≤ z ≤ 2.13 ) = p( z ≤ 2.13 ) - p( z ≤ -2.13 )

                               = 0.9834 - 0.0166 = 0.9668

Plz help I don’t understand how to find x?
Oliga [24]

Answer:

x = -4

Step-by-step explanation:

First lets add 82 + 55 which equals 137, then 137 +47 which equals 184

Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.

-x + 184 = 180

-x = -4

Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.
