Suppose that the amount of a weekly grocery bill of all households in a metropolitan area is distributed with a mean of $140. In a random sample of 49 households selected from this metropolitan area, the sample standard deviation is $35. (Use applet!) a. What statistic is used to analyze this situation? b. Find the statistic and probability that average amount of grocery bill of such a sample will be: i. more than $145, ii. less than $140, iii. between $132 and $148

$97520

step-by-step explanation:

add 6% to the value she got from selling the house.

the answer to this question is 3/19

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

probably the last option
