Answer: 1%
Explanation:
Add up the frequencies in the bottom row: 350+200+245+125+66+10+4 = 1000
There are 1000 families total. Of this total, 10+4 = 14 families have more than six people. I added up the frequency counts for "7 people" and "8 people" to get 14.
Divide 14 over 1000 and we get 14/1000 = 0.014 = 1.4% which rounds to 1%
Answer:
The mean score for Noah is 22.
Step-by-step explanation:
First, you want to add up all of the scores.
19+15+22+10+37+26+37+12+5+37+19+10+39+16+26=330
Now, you want to divide 330 by how many scores were listed, so 15 scores.
330/15=22.
N= P-180. so the computer would originally be 720 dollars. reduced by 25%, or 180, the new price is 540.
Answer:
Step-by-step explanation:
y ≤ x − 5
1<10-5
1<5
Pair: (10,1)
y ≤ −x − 4
-10<-1-5
-10<-6
Pair: (1,-10)
Answer:
d(t) = -100t
Step-by-step explanation:
The general expression for the linear model is:
Since the submarine already starts at sea level, b=0:
The constant "m" is the rate at which the submarine descends in feet per minute. Considering depth as a negative quantity, m=-100
The linear model that represents the depth of the submarine relative to sea level, in feet, after t minutes is d(t) = -100t.
