Asap! planes x and y and points c, d, e, and f are shown.

vertical plane x intersects horizontal plane y. point d is on the left half of plane y. point f is on the bottom half of plane x. point e is on the right half of plane y. point c is above and to the right of the planes.

which statement is true about the points and planes?

the line that can be drawn through points c and d is contained in plane y.
the line that can be drawn through points d and e is contained in plane y.
the only point that can lie in plane x is point f.
the only points that can lie in plane y are points d and e.

Otto used 6 cups of whole wheat flour and cause x cups of white flour in the recipe. what is the equation that can be used to find the value of y, the total amount of flour that otto used in his recipe and what are the constraints on the value of x and y? a y=6x; x is any interger greater than the equal to 0 and y is an interger greater than the equal to 6? b y=6x; is any real number greater than or equal to 0 and y is any real number greater than or equal to 6? c y=+6; x is any intger greater than or equal to 0 and y is an intger greater than or equal to 6? d y=x+6; x is any real number greater than 0 eqaul to 0 and y is any real number greater than or eqaul to 6? [someone answer this with a b c or d simplyactaully answer it this took forever to type on my phone] you. ill even raise the number of points get

Summary statistics given for independent simple random samples from two populations. use the pooled t-interval procedure to obtain specified confidence interval. x1=71.6, s1=3.9, n1=11, x2=67.9, s2=3.4, n2=9 determine a 99% confidence level.
