Answer:
70 times
Step-by-step explanation:
5 consecutive even integers: 2n, 2n+2, 2n+4, 2n+6, 2n+8 for any integer n The sum of the two smallest of five consecutive even integers is 50 less than the sum of the other three integers: 2n + 2n+2 = 2n+4 + 2n+6 + 2n+8 - 504n + 2 = 6n -3234 = 2nn = 17 The smallest integer in our sequence is 2n = 2*17 = 34 Check:2n + 2n+2 = 2n+4 + 2n+6 + 2n+8 - 5034 + 36 = 38 + 40 + 42 - 5070 = 120 - 5070 = 70
To get the improper fraction of 4.8 you can first get the mixed number of 4 and 4/5. You must then convert 4 into fifths and add the two fractions together 4 times 5 is twenty so you must add 20/5 plus 4/5 and the improper fraction you end up with is 24/5.
14/20=0.7 or 70% are soft-centred. If we take two candies we have three possibilities associated with probabilities:
Both soft-centred: 0.7²=0.49 or 49%
Both hard-centred: 0.3²=0.09 or 9%
One of each: 2×0.3×0.7=0.42 or 42%. 49+9+42=100%. So these are all the possible outcomes.
Answer:
Step-by-step explanation:
Add 9 to both sides:
Subtract 6a from both sides:
Divide both sides by -8:
