Which best describes how an accretionary wedge forms? Group of answer choices as a result of the accumulation of sediment and oceanic crust being scraped off a descending oceanic plate during subduction as a result of sediment moving from the continental shelf out across the continental slope during subduction as a result of sediment washing down off the mid-ocean ridge as a result of water flow down submarine canyons after large tectonic events

Accumulation of sediment and oceanic crust being scrapped off a descending oceanic plate during subduction.

Step-by-step explanation:

Accretionary wedge occurs when there is an accumulation of mostly marine sediments and rocks moving down an oceanic plate during subduction. The plate which moves downward is usually an oceanic plate while the plate which moves above could either be a continental or oceanic plate. The accretionary wedge has the shape of a prism.

A mixture of badly formed rock known as Melange form the Primary rock type in an accretionary wedge.

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;
