Question
After attending a car show, Katrina decides to start saving for a car. She places $50 of her most
recent paycheck into a jar and commits to adding $150 every month to save for a down
payment. Her total amount saved for the car, y, after x months can represented by this
equation:
y = 150x + 50.
Complete the table to determine the number of months that Katrina will need to save to have
enough for a $2,600 down payment on a car.

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

if the probability is 1/12, 75 people will receive a $25 gift card
