The 1st and 3rd choices are irrational. The other 2 are rational. Irrational numbers are numbers that you can't make a simple fraction out of.

If we think about a normal curve / bell curve and the 68-95-99.7 rule, we know that the majority of data will lie within 1, 2, or 3 standard deviations from the mean. The mean is in the center of the curve, and to each side of the mean, 34% of the data lies 1 standard deviation on either side of the mean. Therefore, we need to add and subtract one standard deviation from the mean.

85 + 12 = 97

85 - 12 = 73

Correct Answer: B. 73 - 97

Hope this helps!! :)

Correct answers are $D + D(\frac{1}{5})$ and $1.2D$ i.e. Options A & D

<u>Step-by-step explanation:</u>

Options for this questions are:

A)D+1/5D

B)D+20

C)D+20D

D)1.2D choose two answers.

We have , Crispy Clover, a popular vegetarian restaurant, introduced a new menu that has 20%, percent more dishes than the previous menu. The previous menu had D dishes.We need to find expressions could represent how many dishes Crispy Clover's new menu has . Let's find out:

Initially , Number of dishes are D . Then 20% more dishes are there in menu

⇒ $\frac{D(20)}{100}$

So , Total Number of Dishes are

⇒ $D + \frac{20d}{100}$

⇒ $D + \frac{20d}{20(5)}$

⇒ $D + D(\frac{1}{5})$

⇒ $D + D(0.2)$

⇒ $1.2D$

Therefore, Correct answers are $D + D(\frac{1}{5})$ and $1.2D$ i.e. Options A & D .

what are the coordinates of the point on the directed line segment (-1,-2) to (9,-10) that partitions the segment into a ratio o

Ymorist [56]

Answer:

[6.5,-7.25]

Step-by-step explanation:

Given the partitioning ratio as 3:1

#Find the length of the x-coordinate and multiply by the ratio:

x length=9--1=10

=> $\frac{1}{4}\times 10=2.5$

#We subtract 2.5 from the x-max to get the point=9-2.5=6.5

#Find the length of the y-coordinate and multiply by the ratio:

x length=-9--2=-7

=> $\frac{1}{4}\times -7=-1.75$

#We subtract -1.75 from the y-max to get the point=-9--1.75=-7.25

Hence, the coordinates that partitions the segment into a ratio of 3 to 1 is [6.5,-7.25]
