Which of these expressions represent the sum of 3 and n?

Dmitrij [34]

Don't really need to post the options to know what the expression(s) should look like.

"Sum of" tells you its addition and because it's addition the order of the two terms (the 3 and the N) don't matter.

Your correct expressions are:

3 + n
or
n + 3

Determine the first four numbers of N if N is <img src="https://tex.z-dn.net/?f=N%20%3D%20%20%5Csqrt%7B122436486072...2400%7D

Anestetic [448]

Answer:

1106 . . . or
3499

see below for explanation

Step-by-step explanation:

The first four digits of the root depend on whether the exponent in scientific notation is even or odd.

If it is even, then the mantissa of the root is ...

$N \approx\sqrt{1.2243648607}\approx 1.106\dots$

If it is odd, then the mantissa of the root is ...

$N \approx\sqrt{12.243648607}\approx 3.499\dots$

This data set represents the number of cups of coffee sold in a café between 8 a.m. and 10 a.m. every day for 14 days.

Nataly [62]

Answer:

Step-by-step explanation:

The difference between the third quartile and first quartile is known as interquartile range.

The upper quartile is the median of upper half of the data.

The lower quartile is the median of lower half of the data.

Let's arrange in least to greatest:

4,5,6,6,7,8,9,9,10,10,12,12,14,15

The upper half of the data is 9,10,10,12,12,14,15

The median is the 4th number here, so 12. Thus, third quartile = 12

The lower half of the data is 4,5,6,6,7,8,9

The median is the 4th number here, so 6. Thus, first quartile = 6

Interquartile range (difference in third quartile and first quartile) = 12 - 6 = 6

42 point Plus brainliest slove it g(x) = (x + 2)(x − 1)(x − 2)

Dmitry_Shevchenko [17]

Answer:

x = -2,1, 2

Step-by-step explanation:

g(x) = (x + 2)(x − 1)(x − 2)

Assuming we are looking for the roots

0 = (x + 2)(x − 1)(x − 2)

Using the zero product property

0 = x+2 0 =x-1 0 = x-2

x=-2 x = 1 x =2
