Where would i draw my reflection

The coordinates for the reflection of quadrilateral ABCD is..

A'(-7,2) > A'(-7,-2)

B'(-7,4) > B'(-7,-4)

C'(-4,6) > C'(-4,-6)

D'(-1,6) > D'(-1,-6)

Step-by-step explanation:

Since it's being reflected over the x-axis, the x remains the same and the y becomes a negative.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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;
