You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.
But, 3.5^2 + 4.5^2 is not equal to 5.5^2.
Answer:
5; 10; 20.
Step-by-step explanation:
the 1st step is shown with orange colour, described on the right part; the 2d step is shown with blue colour, described on the right part of the picture.
Answer:
Point estimate for the population variance = 3.92 *
.
Step-by-step explanation:
We are given that a sample of 5 strings of thread is randomly selected and the following thicknesses are measured in millimeters ;
X X -
1.13 1.13 - 1.188 = -0.058 3.364 * 
1.15 1.15 - 1.188 = -0.038 1.444 *
1.15 1.15 - 1.188 = -0.038 1.444 * 
1.24 1.24 - 1.188 = 0.052 2.704 * 
1.27 1.27 - 1.188 = 0.082 <u> 6.724 * </u>
<u> </u>
<u>= 0.01568 </u>
Firstly, Mean of above data,
=
=
= 1.188
Point estimate of Population Variance = Sample variance
=
=
= 3.92 *
.
Therefore, point estimate for the population variance = 3.92 *
.
Answer:
5, 48, 4, 32, 3, 24
Step-by-step explanation:
do not get intimidated by this question , its very easy
let's break it ike this, 543 x 18
get the bigger number first , 543
each digit will be multiply by the opposite number which it's 18
READY? watch! 543 ( we'll separate them)
1. 5x (18) we'll break the 18 watch. 1 and 8 and we'll multiply each by 5
<u>5</u>x1= 5
5x8= 48.
2. 4x 18
<u>4</u>x1=4
4x8=32
3. <u>3</u>x 18
3x1=3
3x8= 24
