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}

What is the slope of the line through (3, 2) and (-3 ,4)
Delicious77 [7]

Answer:

Slope = -\frac{2}{3}

Step-by-step explanation:

Slope = \frac{rise}{run}

Slope = \frac{y2-y1}{x2-x1}

Slope = \frac{4-2}{-3-3}

Slope = -\frac{4}{6}

Slope = -\frac{2}{3}

The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is y + 7 = (x – 10). What is the stan
olya-2409 [2.1K]


That point slope equation given does not pass through those points, the point slope equation y + 7 = -0.4(x - 10) does, though. The standard form of that would be

2x + 5y = -15

You can get that by distributing the -0.4 out

y + 7 = -0.4x + 4

You can then add 0.4x to both sides, and subtract 7 from both sides to get

0.4x + y = -3

Now some teachers may accept this, but in correct standard form the coefficient of x is a whole number, so you have to multiply both sides by 5 to get rid of the decimal, and you get

2x + 5y = -15
