btw hurry im timed plss :)

Answers

Answer 1

Answer:

Answer:

31.8

Step-by-step explanation:

I will assume that

"-6.1(-4.1) +6.8="

means (-6.1)*(-4.1) +6.8=

(-6.1)*(-4.1) = 25

25 + 6.8 = 31.8

Answer 2

Answer:

Answer:

31.81

Step-by-step explanation:

-6.1 * -4.1 = 25.01

+ 6.8 = 31.81

The lengths of two sides of a triangle are 12 inches and 4 inches. Which of the following dimensions is the third side of this triangle?9 inches
8 inches
7 inches
6 inches

Answers

According to the rule that any 2 shorter sides have to be longer (not equal) to the other side, the answer is 9 inches.

4 + x > 12
x > 8

The answer is 9 inches, as x>8 doesn't include 8 in its domain.

What is the standard deviation of the data? Round to the nearest whole number.

100

130

Answers

In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it. For this we get: 6724, 2209, 10404, 11664, 729, 1764, 12544, 9, 529, 71824, 1444, 1024. Now we sum all of these up and take the average by dividing the sum by 12. Doing this we get 120868/12=10072. The last step is the take the square root of that number to get the standard deviation. The final result is 100.

The standard deviation of the given set is:

S = 130.

How to get the standard deviation?

Here we have the set:

{700, 735, 680, 890, 755, 740, 670, 785, 805, 1050, 820, 750}

First, we need to get the mean of the set which is:

$M = (700 + 735 + 680 + 890 + 755 + 740 + 670 + 785 + 805 + 1050 + 820 + 750)/(12) = 704.17$

Then the standard deviation is:

$S = \sqrt{((700 - 704.17)^2 + (735 - 704.17)^2+ (680 - 704.17)^2 + ... + (820 - 704.17)^2 + (750 - 704.17)^2)/(12)} = 129.5$

So we conclude that the standard deviation, rounded to the next whole number, is S = 130

Simplify the expression: 1/1+cot^2xa.sec^2x
b.csc^2x
c.sin^2x
d.cos^2x
e.tan^2x

Answers

$\sin ^( 2 ){ x } +\cos ^( 2 ){ x } =1\n \n \frac { \sin ^( 2 ){ x } }{ \sin ^( 2 ){ x } } +\frac { \cos ^( 2 ){ x } }{ \sin ^( 2 ){ x } } =\frac { 1 }{ \sin ^( 2 ){ x } } \n \n 1+\cot ^( 2 ){ x } =\csc ^( 2 ){ x }$

Because of this...

$\frac { 1 }{ 1+\cot ^( 2 ){ x } } \n \n =\frac { 1 }{ \csc ^( 2 ){ x } }$

But...

$\frac { 1 }{ \csc ^( 2 ){ x } } =\sin ^( 2 ){ x }$

Therefore:

$\frac { 1 }{ 1+\cot ^( 2 ){ x } } =\sin ^( 2 ){ x }$

log3(2x-5)=2

Answer is 41/2. Why?

Answers

I guess that your question is:

$log[6*(2x-5)]=2$

So, we can apply this property of log

$log_b~(a)=c\Leftrightarrow a=b^c$

them...

$log[6*(2x-5)]=2$

$6*(2x-5)=10^2$

$12x-30=100$

$12x=100+30$

$12x=130$

$x=(130)/(12)$

simplifying

$\boxed{\boxed{x=(65)/(6)}}$
