Answer:

1/13 chance or roughly 7.7% chance.

Step-by-step explanation:

There are 4 Kings in a standard 52-card deck. If one King was to be pulled out, you'd get a probability of 4/52 chance of pulling a king. Simplified, 4/52 is  1/13 chance.

Answer:

1/7

Step-by-step explanation:

They traveled 5/7 of the distance on Saturday.

That left 2/7 of the distance as the remaining distance.

They traveled half of 2/7 of the distance on Sunday.

1/2 of 2/7 = 1/2 × 2/7 = 2/14 = 1/7

Answer: 1/7

Pls help ill give u brainliest
Monica [59]

Answer:

Answers:

Rate of change = -5

Initial value = 25


Step-by-step explanation:

Each time x increases by 2 (eg from x = 1 to x = 3), the value of y drops by 10 (eg from y = 20 to y = 10)

Therefore the slope is...

slope = rise/run = (change in y)/(change in x) = -10/2 = -5

slope = -5

So each time x increases by 1, y will decrease by 5

Flip things around: each time x decreases by 1, y will increase by 5

So the pair (x,y) = (1,20) shown in row 1 of the table leads to (0,25) based on the rule above. Another way to see this is to plug m = -5, x = 1 and y = 20 into y = mx+b and solve for b to get b = 25

Suppose the equation for line a is given by 2x-5y=15. If line a and b are parallel and the point (-10, 3) lies on line b, then w
Step2247 [10]

Answer:

Line b is represented by the equation y = \frac{2}{5}\cdot x + 7.

Step-by-step explanation:

Let be line a represented by 2\cdot x - 5\cdot y = 15, whose explicitive form is:

5\cdot y = 2\cdot x - 15

y = \frac{2}{5}\cdot x - 3

As line b is parallel to line a, its slope is equal to \frac{2}{5}. Two lines that are parallel to each other have the same slope but different y-intercept. In addition, we know that point (-10, 3) lies on that line and we must find the y-intercept (k):

y = \frac{2}{5}\cdot x +k

If x = -10 and y = 3, then:

3 = \frac{2}{5}\cdot (-10)+k

k = 3+\frac{2}{5} \cdot (10)

k = 7

Line b is represented by the equation y = \frac{2}{5}\cdot x + 7.
