The expression that's always true is that D. a+c > b+d.
<h3>How to illustrate the information?</h3>
From the information given, it should be noted that we are told that a is less than b and c is less than d.
We are also informed that all the variables that are given are less than 0. Let's say a = -1, b = -2, c = -3 and d = -4.
Therefore, the expression that's always true is that. a+c > b+d. This will be:
= (-1 - 2) > (-3 - 4)
= -3 > -7
Based on the information given, the expression that is true is a+c > b+d.
Therefore, the correct option will be D.

The perimeter of a given shape implies the <u>sum</u> of all its <u>sides</u>. While the area of a given shape is the <em>total value</em> of <u>space</u> it would <u>cover</u> on a 2-dimensional <em>plane</em>.
The perimeter of the shape is 104 cm.
The area of the shape is 640 .
The <u>perimeter</u> of a given shape implies the <u>sum</u> of all its length of <em>sides</em>., such that the<u> value</u> of each <em>individual side</em> is summed to a <em>total value</em>.
The area of a given shape is the <em>total value</em> of space it would <u>cover</u> on a 2-dimensional <u>plane</u>. The area of <u>shapes</u> depends on the <em>type</em> of <u>shape</u>.
In the given question, the given <u>shape</u> has 12 <em>sides</em>. Some of these <em>sides</em> can <u>sum</u> up to a given <u>length</u> as shown in the diagram.
So that;
perimeter = 2 + 32 + 10 + 10 + 2 + 32 + 8 + 8
= 104 cm
Thus, the <u>perimeter</u> of the shape is 104 cm
ii. The <em>area </em>of the shape = length x width
= 32 x 20
= 640
Therefore, the area of the given shape is 640 .

16/17 = 22+16/x
16x = 17(38)
x= 40.375
The answer is 4 because k+2 would be 2 then times by 6 which is 12 then subtract 8 would be 4
Answer:
The 98% confidence interval for the mean amount of money spent on lunch per week for all students is between $13.3 and $16.7.
Step-by-step explanation:
A confidence interval has the following format.
In which is the mean of the sample and M is the margin of error.
In this problem, we have that:
The 98% confidence interval for the mean amount of money spent on lunch per week for all students is between $13.3 and $16.7.
