What is the probability of choosing a

Mathematics
1 answer:
sladkih [1.3K]3 years ago
3 0

Answer:

Probability of choosing a penny at random is 1/5 or 0.2

Step-by-step explanation:

For many probabilities like this one, you have to add the total of materials or items together, even if they are different colors, shape, coin type, etc.

you have 12 pennies, 19 nickles, 14 dimes, and 15 quarters. This adds up to a total of 60 coins. Twelve of those are pennies.

You have twelve possible pennies to choose at random from a total of 60 in a bag.

So 12/60/ This simplifies to a probability of 1/5. If you divide 1 by 5 than it would be 0.2

The probability of choosing a penny from a bag of coins is 1/5, or 0.2.

Hope this helps

What is an equation of the line that passes through the points <br> (8,2) and <br> (7,1)?
gogolik [260]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===

Which ordered pair is a solution
NikAS [45]

Answer:

B) Only (-3, 5)

Step-by-step explanation:

Slot in the options into the equation

(-2, 4),

Compare with (x, y)

x = -2,  y =4

y =-3x - 4

4 =( -3 * -2 ) - 4

4 = 6 - 4

This is not true hence, option A is wrong

Using (-3, 5)

x = -3, y= 5

5 = (-3*-3) - 4

5 = 9 - 4

This is correct hence, option B is correct

Option c is wrong because (-2,4) is not a solution to the equation

Option D is wrong because option B is correct

Oksana wrote the equation below on the whiteboard.
Kaylis [27]

Answer:

b = 7

Step-by-step explanation:

6 b + 6 = 48

Subtract 6 from each side

6b+6-6 = 48 -6

6b = 42

Divide each side by 6

6b/6 = 42/6

b = 7
