A ladder rest against a vertical wall .if the top of the ladder is 6m from the foot of the wall and the ladder makes 36° with the ground find the length of the ladder
Answer:
10.21 m
Step-by-step explanation:
|\
| \
| \ L
6 m | \

| 36 deg \
|-------------------------\
For the 36-deg angle, 6 m is the opposite leg. L is the hypotenuse. The trig ratio that relates the opposite leg to the hypotenuse is the sine.
[tex] \sin A = \dfrac{opp}{hyp} [/tex]
[tex] \sin 36^\circ = \dfrac{6~m}{L} [/tex]
[tex] L = \dfrac{6~m}{\sin 36^\circ} [/tex]
[tex] L = 10.21~m[/tex]

A random sample of 197 12th-grade students from across the United States was surveyed, and it was observed that these students spent an average of 23.5 hours on the computer per week, with a standard deviation of 8.7 hours. If we plan to use these data to construct a 99% confident interval, the margin of error will be approximately.
(a.) 0.07
(b.) 0.62
(c.) 1.6
(d.) 8.7
Answer:
The margin of error will be approximately =
(c.) 1.6
Step-by-step explanation:
Sample of 12th-grade students = 197
Average hours spent on computer per week = 23.5 hours
Total hours spent = 4,625 (197 * 23.5) hours
Standard deviation = 8.7 hours
Confidence interval = 99%
Square root of sample size = [tex]\sqrt{x}[/tex] = 14.04
Standard deviation/square root of sample size = 8.7/14.04 = 0.6196
Z value at 99% confidence = 2.58
Margin of error = 0.6196 * 2.58
= 1.59857
= 1.6
This question can be determined by the concept of standard deviation. The margin of 1.6 error will be approximately.
Given:
Random sample of 12th-grade students = 197
Average hours spent on computer per week = 23.5 hours
Therefore,
Total hours spent by 12th grade students = [tex]\bold{(197 \times23.5=4629.5)hours}[/tex]
Standard deviation = 8.7 hours (Given)
Confidence Interval =99% (Given)
Square root of random sample size = = 14.04
[tex]\bold{\dfrac{Standard\: deviation}{Square\: root\: of\: sample\: size} =\dfrac{8.7}{14.04 } = 0.6196}[/tex]
Therefore,
Z value at 99% confidence = 2.58
Margin of error = [tex]0.6196 \times2.58[/tex]
= 1.59857 error
= 1.6 error
Thus, the correct option is (c) 1.6 error.

S = {0,1}
Is Set S closed under addition?
Why or why not?
9514 1404 393
Answer:
no; 1+1=2, a number not in the set
Step-by-step explanation:
A set is closed under addition if the addition of any two members of the set results in a member of the set.
0 + 0 = 0 . . . in the set
0 + 1 = 1 . . . in the set
1 + 0 = 1 . . . in the set
1 + 1 = 2 . . . not in the set. The set is not closed under addition.

What is the difference between a tax credit and a tax deduction?
Answer:
A deduction can only lower your taxable income and the tax rate that is used to calculate your tax. This can result in a larger refund of your withholding. A credit reduces your tax giving you a larger refund of your withholding, but certain tax credits can give you a refund even if you have no withholding.

Amber is an engineer designing a suspension bridge. She has a tower at each end of the bridge that will hang four diagonal cables. Her design is shown. Explain the process she should use to determine the lengths of her cables. Use complete sentences.
Answer
she should find the length from where the tower begins to where the cable touches the ground, and use that number to be leg B, with the hight of the tower being constant and being leg A. then she uses the two numbers to find the hypotenuse of the new triangle. Repeat this with the other 3 cables and you have the answer! (Note: leg A's length will remain constant, but leg B's length will not because it is reliant on how far away the cables contact the ground in relation to the tower.)
