The figure shows triangle PQR and some of its transformed images on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A triangle labeled PQR is shown on ordered pair 1, 1 and 1, 4 and 3, 1. Another triangle labeled image A is shown on ordered pair 1, negative 1 and 1, negative 4 and 3, negative 1. Another triangle labeled image B is shown on ordered pair negative1, negative 1 and negative 1, negative 4 and negative 3, negative 1. Another triangle labeled image C is shown on ordered pair negative 5, 1 and negative 5, 4 and negative 3, 1. Another triangle labeled image D is shown on ordered pair negative1, 1 and negative 1, 4 and negative 3, 1.

Which of the four triangles was formed by a translation of triangle PQR?
A.
B.
C.
D.

i dont understand the question? ?

step-by-step explanation:

about 0.75 hours

step-by-step explanation:

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;

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
