Answer:

1/18.

Step-by-step explanation:

P(A) = 1/3 (as there are 3 cards with one marked A).

P(3 on the die) = 1/6 (as there are 6 sides on a die).

P(A then 3) = 1/3 * 1/6 = 1/18.

Note: the probabilities are multiplied because the 2 events are independent.

Manuel incorrectly claimed that the surface area of the cylinder shown is about 190.0 in.2. Use a formula to find the surface ar

Kitty [74]

Answer:

25.9%

Step-by-step explanation:

Note: you did not provide any attached image detailing the dimension of the cylinder however, let us arrange some dimension for explanation purpose

let the dimension of the cylinder be

radius= 3in

height= 5 in

Step two

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr2

substitute

T. S. A. =2*3.142*3*5+2*3.142*3^2

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

%error= actual -expected/expected*100

%error= 190 -150.816/150.816*100

%error= 39.184/150.816*100

%error= 0.259*100

%error= 25.9%

Now, you can use the dimension you have for the cylinder to calculate the total surface area, from there, you can solve for the error by following the steps above

If the base of a rectangle is 12 cm and the area is 250.8 cm2 what is the height of the rectangle

Sergio039 [100]

So to find the area of a rectangle, the formula is
B (base) x H (height)= A (area)
12 cm x H = 250.8 cm^2
H= 250.8 / 12
H= 20.8 cm

There are a total of 21 students in the choir and the drama club. There are 7 more students in the choir than the drama club. Wr

PolarNik [594]

Answer:

The number of students in the drama club is 7 and the number in the choir is 14

Step-by-step explanation:

X = Number of students in choir club

Y = Number of students in drama club

First equation:

x + y = 21

Since we know that there are 7 more students in the choir club than the drama club, that means:

x + 7 = y

A little trick that you can do to find y is this:

21 students in the choir and drama club - 7

=> 14

Meaning that y is 14

So lets go back into our second equation:

x + 7 = 14

7 + 7 =14

x=7

Plug both variables in:

7 + 14 = 21

So that means that there are 7 students in the drama club and 14 students in the choir club.
