340 is (340-380)/20=-2, or 2 standard deviations below the mean.
420 is (420-380)/20=2, or 2 standard deviations below the mean.
95% of values lie within 2 standard deviations of the mean, so the answer is 95%.
The answer you are looking for would be D. $3
This is found by divding 50 (number of students) by 5 (number of students per chaperone). This shows there are 10 chaperones.
Multiply 10 and 45 (cost of adult tickets) to get $450. Then multiply 50 and 30 (cost of student tickets) to get $1,500.
Next you'd add 1,500 and 450 together to show the total ticket cost, which is $1,950. Since the organization raised $1,800 already, you'd subtract it from $1,950, to get $150.
Finally, divide $150 by 50 to show how much each student pays.
I hope this helps!
Answer:
x < 16
Step-by-step explanation:
4x < 64
To solve for x, we simply divide by 4 on both sides. This results us with:
x < 16

Answer: that the variable can be any number.
Step-by-step explanation:
So we have a linear equation and we end with a relation of the way:
x = x
an example can be if we have:
2*x + 4 = 2*(x + 2)
if you solve that, you will end with a relationship x = x
this means that any value of x will made that equality true.
so x can be any number.
Answer:
25.92 feet
Step-by-step explanation:
In the first minute, the hot air balloon rises 120 feet.
And it is given that, the balloon rises in a minute only 60% of the height it rose in the previous minute.
Therefore, in the second minute, the balloon rises by (120×0.6) =72 feet
And in the third minute, the balloon rises by (72×0.6) =43.2 feet
Hence, in the fourth minute, the balloon rises by (43.2 ×0.6) =25.92 feet (Answer)
