Answer:

56 cent per ft²

Step-by-step explanation:

Wall dimension = 35 feets * 21.5 feets

Total cost of paint used = 421.40

Area of wall = Area of rectangle = Length * width

Area of wall = 35 feets * 21.5 feets

Area of wall = 752.5 ft²

Cost of paint per square feet:

Total coast of paint / Area of wall

$421.40 / 752.5 ft²

= $0.56 per ft²

= 0.56 * 100 = 56

Leona [35]

Answer:

The right answer is "0.70".

Step-by-step explanation:

The given query seems to be incomplete. Please find below the attachment of the full query.

By using the Bayes' theorem, we get

⇒  P[(X

By putting the values, we get

                                     =\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}

                                     =\frac{(0.20+0.15)}{1-0.20-0.30}

                                     =\frac{0.35}{0.5}

                                     =0.70

Geomtry help please .
BigorU [14]

Answer:

angle ABC= 47°

angle CAD= 38°

Step-by-step explanation:

angle ABC= 180-(49+84)= 47°

because all angles in a traingle add up to 180°

angle ACD= 180-84= 96°

because angle on a straight line add up to 180°

so, angle CAD= 180-(46+96)= 38°

because all angles in a traingle add up to 180°

HOPE IT HELPS ☺️!
