nekit [7.7K]

Answer:

C) 33%

Step-by-step explanation:

To solve for the percentage of success, we first need to find out how many numbers we are working with. In this case, there are 9 numbers (0,1,2,3,4,5,6,7,8).

Since there are 3 "successful" numbers, (0,1,2), we can write the probability as a fraction

3/9 (represents number of successes over number of possible outcomes)

This simplifies to be 33%

If x^2 -8x=48 and x<0, what is the value of x+10?

dsp73

Answer:

Step-by-step explanation:

To calculate x+10, we first need to find x. To do this, we can use the first equation.

We are given the equation:

$x^2-8x=48$

To solve for x, turn one side of the equation into 0 and solve. Therefore:

$x^2-8x=48\\x^2-8x-48=0\\(x-12)(x+4)=0\\x=-4, 12$

So, the possible values for x are -4 and 12.

However, we are also told that x<0. In other words, x must be negative. Thus, we can remove 12. That leaves us with: x=-4.

So:

$x+10\\(-4)+10\\=6$

List two pairs of fractions with a product of 6/40

puteri [66]

Answer:

The product of two fractions can be calculated as follows:

$\frac{a}{b}\cdot \frac{c}{d}=\frac{a \cdot c}{b \cdot d}$

So, the numerator is the product of the numerators of the two fractions, and the denominator is the product of the denominators of the two fractions.

In this problem, we know that the product is 6/40, so:

$ac = 6\\bd = 40$

This means:

$c=\frac{6}{a}\\d=\frac{40}{b}$

So we just need to find 2 pairs of numbers a, b to make c and d integers.

The first choice we use is:

a = 3

b = 2

So we get:

$c=\frac{6}{3}=2\\d=\frac{40}{2}=20$

So the first pair of fractions is

$\frac{3}{2},\frac{2}{20}$

The second choice we use is:

a = 2

b = 10

So we get:

$c=\frac{6}{2}=3\\d=\frac{40}{10}=4$

So the second pair of fractions is

$\frac{2}{10},\frac{3}{4}$
