Answer:
A higher value of standard deviation tells us that there is high variability in the length of the snake from the mean length of the snake.
Step-by-step explanation:
We are given the following information in the question:
Sample of snakes in the Clarmont Zoo's reptile house are as follows:
9, 15, 86, 13, 16, 101, 85, 10, 14, 16, 102
Formula:
where 
are data points, 
is the mean and n is the number of observations.
Sum of squares of differences = 1119.206611 + 753.7520659 + 1896.206612 + 867.5702477 + 699.842975 + 3427.570248 + 1810.115703 + 1053.29752 + 809.6611568 + 699.842975 + 3545.661158 = 16682.72727
Standard deviation:
- Standard deviation tells you how spread out the data is.
- It is a measure of how far each observed value is from the mean.
- A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range.
A higher value of standard deviation tells us that there is high variability in the length of the snake from the mean length of the snake. The data is overspread over a wide range.
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Ok, so yo know what a net is? (not like fishing) like when you unfold the shape
ok so
the left side box surface area is
SA=2(LW+LH+WH)
SA=2(35*12.5+35*32.5+12.5*32.5)
SA=2(437.5+1137.5+406.25)
SA=2(1981.25)
SA=3962.5 cm^2
the right shape (triangular psism)
has 2 triangles and 3 rectangles
SA=2(1/2bh)+2(slantheight times side)+bh
SA=(23 times 20.5)+2(23.5 times 12.5)+(23 times 12.5)
SA=471.5+2(293.75)+287.5
SA=759+595.5
SA=1346.5
box=3962.5 cm^2
trianglar ting=1346.5 cm^2
how much more
box-triangle=3962.5-1346.5=2616 cm^2 more
Answer:
2. 16
3. 46
4. 59
Step-by-step explanation:
5.The measure of smaller angle is 87 degrees.
Step-by-step explanation:
Consider the provided information.
The provided angles are 3x degree and 2x + 25 degree.
Two angles are said to be Supplementary angles if their sum is 180 degree.
It is given that the provided angle are supplementary angles, thus
3x + 2x + 25 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 31
Now, substitute the value of x in first angle i.e 3x.
3(31) = 93
Substitute the value of x in the second angle i.e 2x + 25
2(31) + 25 = 62 + 25 = 87
Hence, the measure of smaller angle is 87 degrees.
