Ivy randomly surveys students in her school to learn about mobile phone password use. of 25 respondents, 14 use a password. based on ivy’s data, how many of the 275 students in her school would be expected to use a password?

154

Step-by-step explanation:

Given : Of 25 respondents, 14 use a password.

To Find: Based on Ivy’s data, how many of the 275 students in her school would be expected to use a password?

Solution:

Let x be the no. of respondents out of 275 who use password

So, A.T.Q

Hence 154 of the 275 students in her school would be expected to use a password

the first one, all those points on the line just make a strait line.

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 .
