Step-by-step explanation:
If u want ti decrease 160 by 6% u just do the following
6\100-160
Answer:
12
Step-by-step explanation:
First let us calculate for the z score using the formula:
z = (x – u) / s
where x = 8, u is the mean = 12.7 years, s is the
standard deviation
z = (8 – 12.7) / 2.5
z = -1.88
From the standard probability tables, the p value at z =
-1.88 is:
P = 0.0301 = 3.01%
Answer:
The sum of first 4n terms is -10n.
Step-by-step explanation:
The formula for sum of n terms of an AP is
It is given that the sum of the first n terms of an A. P. is 2n and the sum of the first 2n terms is n.
..... (1)
..... (2)
Solve equation (1) and (2) by elimination method.
The sum of first 4n terms is
Put the value of a and d.
Therefore the sum of 4n terms is -10n.
The answer to this question is:
<span><span>A. The length is 8 inches, and the width is 5 inches.
</span>The scale factor can be found in the question, <em>"</em></span><span><em>the art team made a scale drawing of the top of the box using a scale of 3 inches to 1 inch"</em>. This means the scale drawing should be divided by a scale factor of 3:1 (simplified into 3).
</span>
The scale factor is then divided with the components provided (24 inches in length, 15 inches in width).
(24/3) = 8 inches
(15/3) = 5 inches
Your answer is length = 8 inches, width = 5 inches.
