Answer:

10/13

Step-by-step explanation:

The probability of the occurrence of an event is ration of the number of possible outcome to the number of total outcome.

Where items are picked without replacements, we have to note the reduction in the number of possible outcome and total number of outcome.

Given that there are 4 pennies, 3 nickels and 6 dimes

The probability of picking a penny or a dime

= 4/(4 + 3 + 6) + 6/(4 + 3 + 6)

= 4/13 + 6/13

= 10/13

What is an equation of the line that passes through the points (6, -5) and (3,0)?

Aliun [14]

Step-by-step explanation:

Hey there!

The equation of a st.line passing through points (6,-5) and (3,0) is;

$(y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)$

[Using double point formula]

Now, Put all values,

$(y + 5) = \frac{0 + 5}{3 - 6} (x - 6)$

Simplify it to get equation.

$(y + 5) = - \frac{5}{3} (x - 6)$

$3(y + 5) = - 5(x - 6)$

$3y + 15 = - 5x + 30$

$5x + 3y + 15 - 30 = 0$

$5x + 3y - 15 = 0$

Therefore the required equation is 5x + 3y - 15 = 0.

Hope it helps...

Y+1=3(x – 4) 2-intercept: C y-intercept:

kiruha [24]

Answer:

x-intercept is (13/3, 0)

y-intercept is (0,-13)

Step-by-step explanation:

change y+1 = 3(x-4) into slope-intercept form:

y+1 = 3x-12

y = 3x-13

y-intercept is (0,-13)

to get x-intercept, plug zero in for 'y' and solve for 'x':

0 = 3x-13

13 = 3x

13/3 = x

x-intercept is (13/3, 0)

What percent of 60 is 27? 22 is 55% of what?

DerKrebs [107]

For this question, set up an equation. 60 times what decimal is 27?

60x=60

x=0.45

Convert this decimal to a percentage by multiplying it by 100:

45%

For this question, set up an equation. 55% (or 0.55) times what number equals 22?

0.55x=22

*Divide both sides by 0.55*

x=40

Hope this helps!!
