Answer:
1/16
Step-by-step explanation:
Possible outcomes when rolling a fair die = 1, 2, 3, 4, 5, 6 (i.e 6 possible outcomes)
Possible outcomes when rolling an even number = 2, 4, 6 (i.e 3 possible outcomes)
Hence P (rolling even number on 1 roll) = 3 / 6 = 1/2
P (Rolling 4 even numbers on 4 rolls) = (1/2)(1/2)(1/2)(1/2) = 1/16
You're going to get a long decimal. Just divide 563 by 6, and you'll get about 93.83333333...
Answer:
y = 10x - 8
Step-by-step explanation:
The slope is "m", or how much the y-value changes on a line when the x-value changes by one.
The y-intercept is the y value of the line when it is intersecting the y-axis, or when the x-value is 0.
To find the slope, take 2 points from the graph and plug into the slope formula:
I'll use (0, -8) and (1,2).
Plug into the formula.
10
Slope = 10
To find the y-intercept, look at the table. What is the y-value when the x-value is equal to 0?
-8
y-intercept: -8
Slope-Intercept form:
y = mx + b
m: slope
b: y-intercept
y, x: leave as variables
y = 10x - 8
A= π r^2, and we don't know r, so we'll have to use r = √C/π.
√C is and infinite number, and the square root of
π is an infinite number, so this problem is impossible.
Answer:
B
Step-by-step explanation:
Okay, so we know they can run 1/4 a mile in 25 seconds. Now we want to know how far they can run in a minute ( 60 sec.). Because there is 25 seconds in 60 seconds 2.4 times, we multiply 1/4 by 2.4. We get 0.6. We know that there is 60 minutes in an hour, so we multiply 0.6 by 60. Now we know they can run 36 miles in an hour/ 36 miles per hour. So that eliminates C and D.
Anyways, B is correct because if you divide 1/4 by 25 you get 0.01. Multiply that by 60 to get a minute. (Because there is 60 seconds in a minute) Which is 0.6. Then multiply it again by 60 for an hour( because there is 60 minutes in an hour), and you get 36 hours.
