Answer:A composite 3D figure is a three dimensional figure made up of basic three dimensional figures such as cubes, prisms, pyramids, cylinders, cones,
Step-by-step explanation:To find the area of a composite figure or other irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
Which numerical pattern is linear?
A.0, 1, 4, 9,
B.1, 2, 4, 8, ...
C.1, 3, 6, 10, ...
D.2, 4, 6, 8, ...
Answer:
D.2, 4, 6, 8, ...
Step-by-step explanation:
This is linear because all successive terms in the numerical pattern have the same difference between them.
sec0 = -[tex]\frac{13}{12}[/tex] and cot0 < 0, find exact values of tan0 and sin0.
Answer:
tan 0 = -2.4
sin 0 = 0.3846
Step-by-step explanation:
sec 0 = -13/12, and cot 0 < 0
the angle 0 is in quadrant II
sec 0 = -13/12 = cos 0 = -12/13 = x/r
=> y = √13²-12²=√169-144=√25=5
so,
tan 0 = y/x = -12/5 = -2.4
sin 0 = y/r = 5/13 = 0.3846
Answer:
Solution given;
Sec θ=-[tex]\frac{13}{12}[/tex]
cotθ< 0,
It lies in second quadrant.
where sin and cosec is positive.
Now
[tex] \frac{1}{cosθ}=-\frac{13}{12}[/tex]
cosθ=[tex]\frac{12}{13}[/tex]
[tex]\frac{b}{h}[/tex]=[tex]\frac{12}{13}[/tex]
b=12
h=13
By using Pythagoras law
p=[tex] \sqrt{13²-12²}=5 [/tex]
Now
exact values of tan θ=[tex]\frac{p}{b}[/tex]=[tex]\frac{5}{12}[/tex]
since it lies in II quadrant
tan θ=-[tex]\frac{5}{12}[/tex]
and
sinθ=[tex]\frac{p}{h}[/tex]=[tex]\frac{5}{13}[/tex]
since it lies in II quadrant
sin θ=[tex]\frac{5}{13}[/tex]

The heights of seasonal pine saplings are normally distributed with an unknown population mean and standard deviation. A random sample of 20 saplings is taken and results in a sample mean of 310 millimeters and sample standard deviation of 20 millimeters. (a) The EBM, margin of error, for a 98% confidence interval estimate for the population mean using the Student's t-distribution is 11.35. (b) Find a 98% confidence interval estimate for the population mean using the Student's t-distribution. Round the final answers to two decimal places.
Answer:
a) The margin of error for the interval is of 11.35.
b) The 98% confidence interval estimate for the population mean using the Student's t-distribution is between 298.65 and 321.35 millimeters.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 20 - 1 = 19
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.539
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.539\frac{20}{\sqrt{20}} = 11.35[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
Thus, the margin of error for the interval is of 11.35.
The lower end of the interval is the sample mean subtracted by M. So it is 310 - 11.35 = 298.65 millimeters.
The upper end of the interval is the sample mean added to M. So it is 310 + 11.35 = 321.35 millimeters.
The 98% confidence interval estimate for the population mean using the Student's t-distribution is between 298.65 and 321.35 millimeters.

Evaluate cos0 if sin0= sqrt(5)/3
a. 9/5
b. 2/3
c. 5/9
d. 3/2

so
P=√5
h=3
b=[tex] \sqrt{3 {}^{2} - \sqrt{5} {}^{2} } [/tex]

What is 5x(4+3.50+6+2.50)
Answer: the answer is 80
Step-by-step explanation: How i got this answer is i followed the PEMDAS order (parenthesis, exponent, multiplication, division, addition, subtraction)
So according to the order, i had to do the parenthesis first, (4+3.50+6+2.50)
(( what i did was i just broke the problems into 2 so it would be much more easier)) (4 + 3.50 = 7.5) and the next (6 + 2.50 = 8.5) Then you would add those numbers together (7.5 + 8.5 = 16)
We can see that we still have the 5 left over, so now all you gotta do is just multiply now. (16 x 5 = 80)
So the answer u r left off with is 80.
