In order to estimate the average electricity usage per month, a sample of 125 residential customers were selected, and the monthly electricity usage was determined using the customers' meter readings. assume a population variance of 12,100kwh2. use excel to find the 98% confidence interval for the mean electricity usage in kilowatt hours. round your answers to two decimal places and use ascending order.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

thus, the first answer choice, y = sec x, is the correct one

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

d is ur answer hopes this i dont really know how to explain it to u.
