Express the confidence interval 0.333 < p < 0.777 in the form p +/- e.

p= 0.555 ; E= 0.222; then we have 0.555 +/- 0.222

Step-by-step explanation:

The confidence interval goes from 0.333 to 0.777.

To find the p, we need to locate the median of that series of numbers.

The median is 0.555 as is the middle value of that interval.

Now the E corresponds to the deviation or the Error that we can measure.

And since we know that our variance ranges between 0.333 and 0.777, we can sustract 0.333 to p and we can get 0.222. We can also check if we add 0.222 to p, and we can get 0.777.

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 .

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
