Which to temperatures have a sum of 0°c? 2°c and -2°c 2°c and 2°c -2°c and -2°c 2°c and 0°c

2°C and -2°C

Step-by-step explanation:

A number and its opposite sum to zero. (The "opposite" is the number with a minus sign instead of a plus sign, or vice versa.)

(-5,-28)

i graphed to on desmos.

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;
