Title has 2.5 feet, 30inches,0.33 yards
Bax has 1.5yards,54inches,4.5feet
and carol has 42 inches 1.1667 yr and 3.5 feet of ribbonthere total is 126 inches 3.50 yards and 10.5 feet of ribbon
787.50
You multiply 250 by .05 to get 12.50, then you add it to 250 to get 262.50, and multiply it by 3 to get 787.50
Answer:
A.)
Lower Value = 295
Upper Value = 485
B.)
Lower Value = 200
Upper Value = 580
C.)
Lower Value = 105
Upper Value = 675
Step-by-step explanation:
Given that mean (M) = 390
Standard deviation (σ) = 95
Lower Value = mean value - number of standard deviations specified
Upper Value = mean value + number of standard deviations specified
a. Μ ± 1σ of the observations lie between what two values?
Lower Value = 390 - 1(95) = 295
Upper Value = 390 + 1(95) = 485
b. Μ ± 2σ of the observations lie between what two values?
Lower Value = 390 - 2(95) = 200
Upper Value = 390 + 2(95) = 580
c. Μ ± 3σ of the observations lie between what two values?
Lower Value = 390 - 3(95) = 105
Upper Value = 390 + 3(95) = 675
Answer:
1.B 2.H 3. A
Step-by-step explanation:
1. First, find out the percentage of people who voted for Mathematika in survey one.
The total amount of people who voted is 14+17+19, which equals 50. 17/50 people voted for Mathematika, 17/50 = 0.34.
To find out how many people out of 300 will vote for Mathematika, multiply the 0.34 by 300. 300 x 0.34 = 102, so 102 people will vote for Mathetika.
2. You use the same logic for number 2. 14+17+19+20+19+11 = 100, so 100 people voted in total. 34 people voted for Infinitus. 34/100 = 0.34. Multiply 0.34 by 750 to get 255 people will vote for Infinitus.
3. The mean = the average. To find the average, add up all of the numbers, then divide that number by the amount of numbers added together.
7+9+11+13+15 = 55
5 numbers were added together so you divide 55 by 5
55/5 = 11. The mean is 11
9+10+11+12+13 = 55
There were 5 numbers added together
55/5 = 11. Both the means were the same
