2 is 65* 1 is 75
Step-by-step explanation:
Answer:
1.
The radius is given, so the radius is = 10
The radius is doubled to be a diameter, so (10 + 10) = 20 is your diameter
And to solve for circumference, your formula is;
C = 2πr
Where 'r' represents the radius, and 'π'(pi) is 22/7 or 3.14.
Plug in your values:-
C = 2πr
C = 2(3.14) x 10
C = 6.28 x 10
C = 62.8, so your circumference is 62.8.
2.
Your radius is half of your diameter, so,
D/2 = R
D = diameter
R = Radius
49/2 = 24.5 is your radius.
Your diameter is given, so the diameter is 49.
Use the formula we applied for circumference in our other problem;
C = 2πr
C = 2(3.14) x 24.5
C = 6.28 x 24.5
C = 153.86, so 153.86 is your circumference.
We are given with the number of jumps per student. To get the mean, we simply have to add all of them and divide by the number of students
mean number of jumps = <span>203 + 245 + 237 + 233 + 90 + 100 + 100 + 277 + 265 + 264 + 265 + 285 + 288 + 291 + 291 + 290 + 300 + 224 + 200 + 257 + 290 + 279 + 266 + 288) / 24
To get th median, arrange the data from lowest to highest and determine the middle value.</span>
Because of the low amount of dollars used, it is easier to use cents. 500 cents will buy you 250 text messages. You now need to find how much it cost to do one text message. Divide the price for 250 by the amount, and you will find that each text cost 2 cents. Now multiply by the 300 texts to find the total amount. 2 cents times 300 messages is 600 cents, or $6.
$6
