A group of children were asked if they like eating cupcakes or brownies. The table shows the probabilities of the results. Like cupcakes Do not like cupcakes Total Like brownies 0.15 0.15 0.3 Do not like brownies 0.35 0.35 0.7 Total 0.5 0.5 1 Which statement is true?

stop cheating

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

the value of x is 90 - 20 aka 70*, these are complementary angles

step-by-step explanation:

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.
