Stephanie bought 12 roses. she gave away 4 of them. how many roses, r, does stephanie have left? choose the answer that represents the correct equation and solution r – 4 = 12 r = 16 r + 4 = 12 r = 8 12r = 4 r = 3 4 + 12 = r r = 16

The correct equation is r + 4 = 12 and the correct answer is, r = 8

Step-by-step explanation:

Here r represents the remaining roses she has when she lost 4 flowers,

Thus, the total number of flower she has = r + 4

But, the initial number of roses = 12

Therefore, r + 4 = 12

Which is the required equation for finding the remaining flowers.

Also,

⇒

⇒

Which is the required number of the remaining flowers.

⇒ Second Option is correct.

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;
