An R&D team at Tesla is interested in finding the average difference in length of charge of two electric car batteries. They intend to conduct the research to help them choose a battery for the Tesla Model 3. The team takes 40 batteries designed by Tesla and 35 batteries designed a new Taiwanese supplier, and the team measures their duration from a single charge. They run the batteries using a machine. Based on the above scenario, is this test a test of Two Independent Means or Paired Means? Group of answer choices

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

215.92 dollars is the answer

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
