Answer:
Step-by-step explanation:
d = number of dimes
2.80 = 0.1d + 0.25 (d + 8 )
2.80 = 0.1d + 0.25d + 2 Combine like terms
2.80 = 0.35d + 2 Subtract 2 from both sides
0.80 = 0.35d Divide both sides by 0.35
d ≈ 2.29
No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.
The probability will be 3/6 or 1/2
Answers are A and E, this is because you can do 3:12 x 4 = 12:48 and 3:12/4 = 1:4 therefore they are all equal values
1 SD away from mean is 68% of data.
2 SD away from mean is 95% of data.
3 SD away from mean is 99.7% of data.
1 SD away:
190+30=220
2 SD away:
220+30=250
This shows we are on the outer 5 percent of the normal distribution.
Since you said "more", that means we only look at the right side of your 5%, which is only 2.5%
answer is D, 2.5%
Answer:
79,000= 79•10^3
Step-by-step explanation:
so the amount of 0's = the power of 10.
In this situation there is 3 0's . so the power of ten will be 10^3
and then the number before the 0's will equal m
so m = 79 n = 3
And also (just as a side note) you can use the asterisk mark (*) as the multiplication symbol. on most keyboards the command is ctrl + 8. you can also use a bullet point (•) for multiplication symbol the command for that is alt + 0149
