Seven and nine thousands in decimal form
Computer use.
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.

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.

Factor the expression 42a+14b using the gcf
Please figure this out quickly
If you are trying to factor it is 14(3a+b).
But if you are looking for the greatest common factor it is 14.
The GCF of 42a + 14b is 14 which is 14(3a + b).
What is GCF?GCF stands for the greatest common factor of two or more two given terms. A number is GCF of two or more than two terms is the highest term that divides the given terms completely.
Given, 42a + 14b and we have to factor this with a GCF.
In terms of variables a and b, there is no common factor.
In terms of 14 and 42 GCF is 14 as 14 is the highest no. that divides these two nos. completely.
So, 42a + 14b.
= 14(3a + b).

Answer:
A
Step-by-step explanation:
Both triangles are similar triangles!
Length 21 for the top triangle is similar to length 20 for the bottom triangle
Length 29 for the top is similar to b on the bottom.
Length 20 for the top is similar to a on the bottom.
Use the first ratio: 21/20 to find the proportionality constant.
Divide 29 by that constant to get b
Divide 20 by that constant to get a
You end up with b = 580/21 (= 27.61), and a = 400/21 (= 19.047)
Therefore A is the right answer.
8/3+7/5a

Answer:
1. 15x + 10y=-11
15x + 10y + 11=-11 + 11
15x + 10y + 11 = 0
