Answer:
68% of an investment earning a return between 6 percent and 24 percent.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 15
Standard deviation = 9
How likely is it to earn a return between 6 percent and 24 percent?
6 = 15 - 1*9
6 is one standard deviation below the mean
24 = 15 + 1*9
24 is one standard deviation above the mean
By the empirical rule, there is a 68% of an investment earning a return between 6 percent and 24 percent.
Answer: C
: Miriam multiplied correctly, but her third fraction should be .S
Step-by-step explanation: Miriam used the unit conversation upside down. The 7000 g should have been multiplied by 1oz/28.35g
The grams cancel and the division of 7000 be 28.35 results in 246.91 oz Round to 252oz.
Alternative: 7kg (2.21 lb/kg)(16oz/lb)=252.5oz
The kg and lbs cancel and the amount of ounces remains.
1. Four hundred thousand thirty two and ten point one
2. Standard form is adding it out ( 945.35 ) = 900 + 40 + 5 + .30 + .05
3. Expanded form ( 73,890 )
| ten thousands | thousands | hundred | tens | ones | decimal | tenths | hundredths |
7 3 8 9 0 . 0 1
3y-10 is greater to or equal to 47 add 10 to each side. 3y is great than or equal to 37 Now divide 37 by 3 which gives you an answer of 12.33 I hope this helps you!
