Values of cube= 1,2,3,4,5,6 = 6(total)
P(3 or 4) = 2\6 = 1/3 (ans)

Say the cube has sides numbered 1-6 that means there are 6 possible outcomes. 3 and 4 are only two possible outcomes so the probability of that is 2:6. Simply 1:3 or 33%

For what value of x is the expression –4x – 8 equivalent to –9x –1?

Alexeev081 [22]

The value of x where the expression –4x – 8 will be equivalent to –9x –1 will be 7/13.

<h3>How to calculate the value?</h3>

It should be noted that we are simply to find the value of x where the expression –4x – 8 will be equivalent to –9x –1.

This will be:

= +4x - 8 = -9x - 1.

4x + 9x = -1 + 8

13x = 7

Divide

x = 7/13

The value is 7/13.

Find the difference between 7 1/2 and 2 3/4

NNADVOKAT [17]

Answer:

4 $\frac{3}{4}$ or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7 $\frac{1}{2}$ = $\frac{15}{2}$ and 2 $\frac{3}{4}$ = $\frac{11}{4}$

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply $\frac{15}{2}$ x2, it'll equal the same number.

So now we have $\frac{30}{4}$ - $\frac{11}{4}$ , 30-11= 19.

$\frac{19}4}$ simplified is, 4 $\frac{3}{4}$ .

As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.

I hope this helps you!

Write an equation for the orbit of Saturn in the form x^2/a^2 + y^2/b^2 = 1

frozen [14]

Answer:

x²/2166784 +y²/2159989 = 1

Step-by-step explanation:

The relationship between the semi-axes and the eccentricity of an ellipse is ...

e = √(1 -b²/a²)

In order to write the desired equation we need to find 'b' from 'e' and 'a'.

<h3>semi-minor axis</h3>

Squaring the equation for eccentricity gives ...

e² = 1 -b²/a²

Solving for b², we have ...

b²/a² = 1 -e²

b² = a²(1 -e²)

<h3>ellipse equation</h3>

Using the given values, we find ...

b² = 1472²(1 -0.056²) = 2166784(0.996864) ≈ 2159989

The desired equation is ...

x²/2166784 +y²/2159989 = 1
