Answer:
second
Step-by-step explanation:
when dividing two fractions, you must flip the second fraction over and then multiply
6b < 42 implies b < 42 / 6 = 7, so it is <span>b < 7
</span>4b + 12 > 8 implies 4b > 8 - 12 = -4, 4b > -4, and then b > -4 / 4 = - 1
the answe is <span>b < 7 or b > -1 </span>
Answer:
four pack of notebooks for $4.56
We need to divide 4,971 by 10 until its a number less then 10.
4,971 / 10 = 497.1
497.1 / 10 = 49.71
49.71 / 10 = 4.971
Now, 4.971 is less then 10, so, we can write this into scientific notation.
4.971 * 10^?
We need to know what power we add to 10 to get 4,971. We can solve for looking at the number of times we divided. As you can see above, we divided 3 times so that will be the power of 10.
4.971 * 10³
Best of Luck!
Answer:
The height below which 20% of the persons lie equals 169.95 cm
Step-by-step explanation:
Given that
Mean height = 175 cm
Standard deviation = 6 cm
Hence for the given question we need to find the standard variate factor ( Z factor) corresponding to the 20% of the area under the standard normal distribution curve
Using the standard normal distribution tables we have Z factor corresponding to an area of 20% equals ( Z = -0.84166)
Thus we have
