Answer:

Answer choice B

Step-by-step explanation:

There are two possibilities; in the first, the first digit is below 5, in the second, it is above. The probability of the first possibility is 3/8, because there are 3 possible digits below 5 and 8 total digits. In this scenario, the chance of the second digit being below 5 is 2/7, because one of the digits is taken. In the other possibility, which has a chance of 5/8, the probability of choosing a number below 5 is 3/7, since all of them are still available. Doing the arithmetic, you find that the total probability is 2/7. Hope this helps!

Find an equation for the line that passes through the point (0,-1) and has a slope 7/10
Leto [7]

Answer:

y= 7/10x -1

Step-by-step explanation:

Assuming you want the equation is slope intercept form, this is the format for slope intercept: y=mx+b. Since you have the slope, this is your current equation: y=7/10x+b. Next, you want to find the y-intercept. So, plug in the coordinate to the equation. This is what it should look like: -1=7/10(0) +b/ Multiply 7/10 by 0 to get 0. So, here is what you're left with: -1=b. -1 is your y-intercept. Go back to your original equation and plug in the -1. This is your final answer: y= 7/10x-1. Hope this helped!

For every 2 dollars that Pam saves in her account, her brother saves 5 in his account.
Arada [10]
When pam saves 2, brother saves 5

so if Pam has 40

40/2 (the number of dollars Pam saves) = 20 

20 x 5 = 100 ( the number of dollars her bro saves)

her bro has 100 dollars

hope this helps


basically divide 2 from 40 and then multiply the answer with 5, and you get the number of money her bro saves

hope this helps
