There are 130 tickets. 30 of these tickets are worth $5 or $ 10. Therefore, 30 of these 130 tickets are worth $5 or greater. Simplying 30 / 130 gives the probability of 3 / 13 or roughly 23%.
Answer: The name of a polygon with 40 sides is tetracontagon or tessaracontagon.
Slope intercept form is just a way of writing a curve's equation so that the slope and the y intercept is really easy to find.
y=mx+b is the way we write slope intercept form. m is the slope (rise over run) and b is the y value where the curve hits the y axis.
So let's rearrange til the equation looks more like y=mx+b
2x+y=22 (from question)
Subtract 2x from both sides.
y=22-2x
y=-2x+22 (this is the answer to the question, you can stop here if you like)
Now we know some things about this straight line, firstly, it's straight line (x, not x^2 or anything like that), it goes downward from left to right and it is steep, every time we go 1 value along the x axis it goes down 2 values on the y axis. It also hits the y axis at +22.
Complete question is;
Henri conducts an experiment to determine who likes peanut butter more: boys or girls. He has 25 girls and 25 boys taste some peanut butter and then rate it on a scale of 1 - 10 with 1 being cannot stand and 10 being tastes delicious. He finds that the girls had a mean of 7 with a range of 9 and the boys had a mean of 8 with a range of 5. Which statement is true?
A) On average, girls like peanut butter more than boys.
B) The person who rated peanut butter the worst was a boy.
Reactivate
C) Girls varied more in how they liked peanut butter than the boys did.
D) There is not enough information to know if any of the above are true
Answer:
Option C) Girls varied more in how they liked peanut butter than the boys did.
Step-by-step explanation:
From the options the most appropriate will be option C which says: Girls varied more in how they liked peanut butter than the boys did..
This is because in the experiment, henri found out that the girls had a mean of 7 with a range of 9 and the boys had a mean of 8 with a range of 5.
The range of the girls responses are far higher than that of the boys.
So it means their ratings were more varied and not within similar ratings scale.
