15x + 4 would be the algebraic expression
The answer is C because if you replace the variables with 0 and 3, it makes the equation reasonable.
-7/4
Because where the next point meets is 7 across and 4 down. And since the line is going down then the slope is negative
When Determining positive and negative I like to think of it like I’m writing my name on the line, if my name goes down the line then it’s negative, but if my name is going up then it’s positive.
I hope this helps
Answer:
26
Step-by-step explanation:
Given that :
2 out of every 5 people buys vanilla ice cream;
If Total number of ice cream sold in a day = 65 ; how many will be vanilla ;
Probability of purchasing vanilla ; p(vanilla) = 2/5 = 0.4
Hence, expected number who bought vanilla :
p(vanilla) * total number of icecream sold
0.4 * 65 = 26
Hence, about 26 of the 65 icecream sold are vanilla flavor.
