Answer:

≈ 7.6

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (6, 2)

d = $\sqrt{(6+1)^2+(2+1)^2}$

= $\sqrt{7^2+3^2}$

= $\sqrt{49+9}$

= $\sqrt{58}$ ≈ 7.6 ( to the nearest tenth )

PIT_PIT [208]

Answer: D is correct, 52.9%

Step-by-step explanation:

% decrease from 340 to 160, Where 340 is the old number and 160 is the new number

Percent change = (New number - Old number) / Old number x 100%

Percent change

= (160 - 340) / 340 x 100

= (-180) / 340x 100 = -52.94%

marlee spins a spinner and rolls 1-6 # cube. the spinner has 5 equal parts # 1-5 . what is the probability she will spin an even

forsale [732]

The events are independant (i.e. what she rolls on the cube has no impact on how the spinner works). The probability of two independant events is given by:

$P_t = P_{cube} \times P_{spin}$

For the cube, 1/2 the numbers meet our requitment of being even, so:
$P_{cube} = \frac{Desired}{Total} = \frac{even}{total} = \frac{3}{6} =\frac{1}{2}$

For the spinner, there are 3 odds out of 5 (1, 3 & 5) so:
$P_{spin} =\frac{Desired}{Total} = \frac{odd}{total} = \frac{3}{5}$

and then:
$P_T = P_{cube} \times P_{spin}$
$P_T =\frac{1}{2} \times \frac{3}{5}$
$P_T =\frac{3}{10}$

Answer:

$\frac{1}{15}$

Step-by-step explanation:

There are 2 yellow marbles, 3 pink marbles, and 5 blue marbles in the bag, for a total of 10 marbles.

Let's start with the probability that the first marble drawn is pink. Since there are 3 pink marbles out of the 10 total marbles, the probability of this happening is $3/10$ .

Since the first marble is not put back in the bag, there are now 9 marbles left, 2 of then being pink. The chances of drawing a pink marble now is $2/9$ . To find the chances of both of these events happening, multiply them together to get:

$\frac{3}{10}\cdot \frac{2}{9}=\frac{6}{90}=\boxed{\frac{1}{15}}$
