A survey was conducted to determine the percentage of high school students who planned to go to college. The results stated that 82% with a margin of error of +5%. What is meant by +5%? Question 5 options:

The percentage of the entire population of students who plan to go to college is between 77% and 87%

It is unlikely that the given sample proportion result would be obtained unless the true percentage was between 77% and 87%

Five percent of the population were not surveyed

In the sample, the percentage of students who plan to go to college was between 77% and 87%.

Between 77% and 87% of the population were surveyed

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
