Possible prime numbers: 2,3,5

so, P(prime)= 3/6=1/2

so, P(prime,prime)= (1/2)*(1/2)= 1/4 thats your answer

Which simplified fraction is equal to 0.53 repeat ? A.24/46 B.8/15 C.42/90 D.5/9
murzikaleks [220]

Answer:

To see how these fractions are equal, I divided the numerators by the denominators. For instance, you could have 4 over 5 (4/5) and divide 4 by 5 (4/5) to get 0.8. Now you'll do the same thing for the fractions given

24/45=0.533...

8/15=0.533...

48/90=0.533...

5/9=0.5556

As you can see, the only fraction that doesn't equal 0.53, or the outlier, is 5/9 or 0.5556

How much solutions does this equation have?
Evgesh-ka [11]

Answer:

All solutions or infinite.

Step-by-step explanation:

Turn 2y = -4x + 6 into standard form - divide by 2

Y = -2x + 3

2x + y = 3

Substitute the y equation in for y.

2x - 2x + 3 = 3

The x variables cancel out.

3 = 3

Which is true so it means all solutions.

Hope this helps.

For problems a - d, write the function in the form LaTeX: y=ab^x. y = a b x . a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x b) LaTeX: y
elixir [45]

Step-by-step explanation:

To write the equation in LaTeX in form y = ab^x  or ab^x for y = abx .........(1)

(a) LaTeX: y=3\sqrt{4^{2x}}  y = 3 4 2 x can be written in mathematical form as

y=3\sqrt{4^{2x}} ; y = 342x

on comparing with equation (1) we get a =3 and b =4

⇒y = 34^x or 34^x

(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as

y=\frac{\sqrt[3]{5^{3x}}}{2} ; y = 342x

on comparing with equation (1) we get a =0.5 and b =5

⇒y = \frac{1}{2}5^x

(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as

y=8^{x+2}

on comparing with equation (1) we get a =64 and b =8

y = 64 . 8^x

(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}  can be written in mathematical form as

y=\frac{3^{2x+1}}{\sqrt{3^{2x}}} = 3^{x+1} = 3 . 3^x

on comparing with equation (1) we get a =3 and b =3

y = 3 . 3^x
