[tex]3\sqrt{4x^{2} } +2=9[/tex]
solve for x
Answer:
[tex]x[/tex] = [tex]\frac{7}{6}[/tex]
Steps:
3[tex]\sqrt{4x^{2} }[/tex]+2 = 9
3[tex]\sqrt{4x^{2} }[/tex] = 9-2
3[tex]\sqrt{4x^{2} }[/tex] = 7
[tex]\sqrt{4x^{2} }[/tex] = 7 ÷ 3
[tex]\sqrt{4x^{2} }[/tex] = [tex]\frac{7}{3}[/tex]
[tex]4x^{2}[/tex] = [tex](\frac{7}{3})^{2}[/tex]
[tex]4x^{2}[/tex] = [tex]\frac{49}9}[/tex]
[tex]x^{2}[/tex] = [tex]\frac{49}9}[/tex]÷4
[tex]x^{2}[/tex] = [tex]\frac{49}{36}[/tex]
[tex]x^{2}[/tex] = [tex]\frac{49}{36}[/tex]

13. The manager of a clothing store planned to give free turkeys to salespersons selling over $10,000 during the fall harvest sale. Of the 110 salespersons working at the store, only 8 sold over $10,000. What percent of the salespersons received turkeys?
Answer:
7.27% of the salespersons received turkeys
Step-by-step explanation:
Of the 110 salespersons working at the store, only 8 sold over $10,000.
So those earned turkeys.
As a proportion, this is: 8/110 = 0.0727
To find the percentage, we multiply the proportion by 100%. So
0.0727*100% = 7.27%
7.27% of the salespersons received turkeys

Step-by-step explanation:
KM^2=LM*MJ(consequence from the similarity of KLM and JLK )

LM=36/8=4.5
=>S=6/2*(8+4.5)=3*12.5=37.5
In the children’s game Don’t Break the Ice, small plastic ice cubes are squeezed into a square frame. Each child takes a turn tapping out a cube of "ice" with a plastic hammer, hoping that the remaining cubes don’t collapse. For the game to work the cubes must be big enough so that they hold each other in place but not so big that they are too difficult to tap out. In an SRS of 43 "ice cubes" the average width was 29.5 millimeters with a standard deviation of 0.12mm. Construct a 95% confidence level for the true mean width. Group of answer choices
Answer:
(29.46 mm, 29.54 mm).
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution 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 = 43 - 1 = 42
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 42 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.018
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.018\frac{0.12}{\sqrt{43}} = 0.04[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 29.5 mm - 0.04mm = 29.46 mm
The upper end of the interval is the sample mean added to M. So it is 29.5 mm + 0.04mm = 29.54 mm
The 95% confidence level for the true mean width is: (29.46 mm, 29.54 mm).

Suppose you want to buy 100 pens. You can buy 100 pens at a 10% discount at one store where the price is $6.99 per pen. And you can also buy 100 pens at a 15% discount at another store where the price is $7.48 per pen.
Required:
a. What is the price per pen at the first store?
b. What is the price per pen at the second store?
c. What is the total price difference for 100 pens?
Answer:
a. $629.10
b. $635.80
c. $6.70
Step-by-step explanation:
The first thing we need to do is turn these percentages into decimal values by dividing them by 100, this would make 10% into 0.10 and 15% into 0.15. Now we can make the following equations to calculate the total by multiplying the 100 pens by the individual pricer per pen, and then multiplying that product by the 1 minus the discount percentage.
A) (100 * 6.99) * (1 - 0.10) = x
699 * 0.90 = x
$629.10 = x
B) (100 * 7.48) * (1 - 0.15) = x
748 * 0.85 = x
$635.80 = x
C) 635.80 - 629.10 = $6.70
The difference is $6.70 more for the 100 pens in the second store.
