How many times would you expect to role a 2 on a 6 sided die in 50 trials

1 answer:

3 0

The six sided die has 6 sides (with numbers 1,2,3,4,5 and 6). That's why the probability to roll number 2 in one trial is equal to $\frac{1}{6}$ .If you'll dol 50 trials, then you can expect $\frac{50}{6}= \frac{25}{3}$ times to roll number 2 (8 or 9 times).

How tall is the tower? 60° 7 ft 50 ft ? ft Round to the nearest tenth. Enter

Nastasia [14]

Answer:

The height of the tower is 94 ft

Step-by-step explanation:

In a given right angle triangle we will use ''sohcahtoa".

tan (60°) = opp/adj

tan (60°) = x/50

√3 = x/50

x = 50√3

x = 50 × 1.732

x = 86.6

Now, The height of the tower is (x + 7)

86.6 + 7 = 93.6 ≈ 94

Thus, The height of the tower is 94 ft

Y= 1/2x+ 2 to make the x the subject.

timofeeve [1]

Answer:

$x=2y-4$

Step-by-step explanation:

$y=\frac{1}{2} x+2$

"To make x the subject" means to have the equation with all the terms in x on one side. As of now, y is the subject of the equation.

You start by subtracting 2 from both sides, you should get the following.

$y-2=\frac{1}{2} x$

Then you multiply by 2 from both sides, you should end up with the following.

$2(y-2)=x$

Therefore, you get the following.

$x=2(y-2)$

Finally, you distribute and get the answer.

$x=2y-4$

Write a polynomial that represents the length of the rectangle help please !!

disa [49]

Answer:

$\textsf{Length}=0.8x^2-0.7x+0.7\quad \sf units$

Step-by-step explanation:

Area of a rectangle = width × length

Therefore, to find the length of the rectangle, we need to divide the area by the width.

Using long division:

$\large\begin{array}{r}0.8x^2-0.7x+0.7\phantom{)} \\x+0.5{\overline{\smash{\big)}\,0.8x^3-0.3x^2+0.35x+0.35\phantom{)}}}\\-~\phantom{(}\underline{(0.8x^3+0.4x^2)\phantom{-b))))))))))))))}}\\0-0.7x^2+0.35x+0.35\phantom{)}\\ \underline{-~\phantom{()}(-0.7x^2-0.35x)\phantom{-b)))))}}\\ 0.7x+0.35\phantom{)}\\\underline{-~\phantom{()}(0.7x-0.35)}\\ 0\phantom{)}\end{array}$

Therefore, the length of the rectangle is:

$0.8x^2-0.7x+0.7$

jeka57 [31]

X : the gas used by first car in 1 particular week
y : the gas used by second car in 1 particular week
$x + y = 60 \\ x = 60 - y$
$30x + 35y = 1975 \\ 30 \times (60 - y) + 35y = 1975 \\ ... \\ y = 35 \\ x = 60 - y = 60 - 35 = 25$
