Jamar rolls a 1-6 number cube three times. What is the probability he will roll an even number, then a 6, then a 4?

Answers

Answer 1
Answer: Probability = 1/2 * 1/6 * 1/6 = 1/72
So your answer would be 1/72
Answer 2
Answer:

there is 2, 4, and 6. you have 3/6 chances of rolling even in one roll.  you have 9/18 chances to roll an even number. this is because there are 18 possible outcomes, 6 times 3, and 3 times 3. to roll a six you have 1/6 chances for one roll, miltiply it again and you get 3/18 chances to roll a six. you also have 3/18 chances to roll a 4.

there are a total of 100 balloons.if the ratio of yellow balloons to blue balloons is 8 to 12,how many of them are yellow?

Answers

The ratio of yellow balloons to blue balloons is 8:12
Then there are 100 balloons. Making the equation, we are able to have:
8X + 12X = 1000
20x = 1000
X = 50.

Yellow balloons = 8x = 8 * 50 = 400 yellow balloons
Blue balloons = 12X = 12 * 50 = 600 blue balloons

So there are  400 yellows balloons.

in the usa, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size. use the function to determine the x and y intercept. State the meaning of each in terms of this problem situation

Answers

Answer:

x intercept = 8

y intercept = -24

Step-by-step explanation:

In the USA, the shoe sizes or men are approximated by the equation 3f-s=24, where f represents the length of the foot in inches and s represents the shoe size.

When we represent this equation using a graph, we mark the independent variable on the x axis and the dependent variable on the y axis.

Here the foot length is the independent variable and the shoe size is the dependent variable. Hence we take foot length on x axis.

To get x intercept put y=0, f = = 8 inches .

This is the point from which where we start our shoe size.

The y intercept , s = -24.

Answer:

Also the average shoe size is 10.5

Step-by-step explanation:

Plug in 11.5 in for f
