One fourth of 320 m is 80 meters.
hope I helped! any other questions I'm happy to answer.
Answer:
p = 22
z = 8
Step-by-step explanation:
Average is sum of the terms divided by number of terms.
<u>Question # 1:</u>

Answer:
The mean of Sample #2 is 8
The mean absolute deviation for Sample #2 is 4.08
Step-by-step explanation:
To find the mean for Sample #2, you find the sum of the values in the set and divide it by the number of elements in that set.
18+14+0+7+5+7+10+7+6+9+12+3+14+4+11+6+0+10+9+5+0+16+11+2+4 = 200
200 ÷ 25 = 8
To find the mean absolute deviation for Sample #2, you calculate how far away each data point is from the mean using positive distances. These are the absolute deviations. Afterward, you add those deviations together and divide the sum by the number of data points.
10+6+8+1+3+1+2+1+2+1+4+5+6+4+3+2+8+2+1+3+8+8+3+6+4 = 102
102 ÷ 25 = 4.08

Bea has $550 more money than Alessandro after 12 months.
Explanation:
So let start with writing the equation for Alessandro money. So we know that the current amount in his/her bank account has $2,400 and she saves $250 per month. So the equation that best fit these terms is:
y
=
250
x
+
2
,
400
Bea has $1,750 in his/her bank account and saves $350 per month. So the equation that best fit these terms is:
y
=
350
x
+
1
,
750
So for x for both of these equations is 12. So let plug the number in
Alessandro:
y
=
250
(
12
)
+
2
,
400
y
=
3000
+
2400
y
=
$
5400
after 12 months
Bea:
y
=
350
(
12
)
+
1750
y
=
4200
+
1750
y
=
$
5950
after 12 months
So subtracting $5950 and 5400 gives us a $550

Answer:
$134.40
Step-by-step explanation:
The markup is 28% of 105, or .28(105) = $29.40
Thus the retail price is $105 + $29.40 = $134.40
