• 2 Negatives = [Positive]

• 1 positive & 1 negative = [Negative]

• 2 positives = [Positive]

• 1 negative & 1 positive = [Negative]

° So, this means that your answer most likely will equal a NEGATIVE number because you have 1 NEGATIVE (-3) number and 1 POSITIVE (“c” or 4.2) number.

-3c

= -3(4.2)

= -12.6

Therefore, your answer is: -12.6

Good luck on your assignment and enjoy your day!

the dataset is a collection of numbers connected by theme. There are three ways to work with datasets: mean, median, and mode. The mean is the average of the dataset, the median is the median of the dataset, and the mode is the number or value that occurs most often in the dataset.

Standard deviation of a data set is the square root of the calculated variance of a set of data. The formula for variance (s2) is the sum of the squared differences between each data point and the mean, divided by the number of data points.

Answer:

Step-by-step explanation:

recall that perpendicular lines have slopes that are opposite reciprocals. if u don't know what opposite reciprocals are, according to study.com they are, "The term opposite reciprocals refers to two numbers that have opposite signs and are flipped fractions of each other." for example, 1/2 and -2 are opposite reciprocals.

also recall that the formula to find the slope of a line is m=y2-y1/x2-x1

to solve this problem, we need to go through all of the options and find the slope of that line using the given point and point (0,4). After that, we need to check if that slope is equal to 1. One is the opposite reciprocal of -1, and -1 is the slope of the equation y= -x+4. if the slope is equal to 1, the line will be perpendicular to the line y= -x+4.

lets do the math now:

option a)

m=y2-y1/x2-x1

m=12-4/6-0

m=8/6

m=4/3

this line isnt perpendicular to y= -x +4 cuz the slope is 4/3, which isnt equal to 1

option b)

m=y2-y1/x2-x1

m=0-4/6-0

m=-4/6

m= -2/3

this line isnt perpendicular to y= -x +4 cuz the slope is -2/3, which isnt equal to 1

--------------

ok girl i dont wanna do all the rest of the calculations. just keep doing the same thing with all the other options until you find something that has a slope of 1.

Answer: 480

Step-by-step explanation:

To solve this, you need to set up a proportion: 200/2.5 x/6

The 200 represents the km, and the 2.5 and 6 represent the hours. You can either solve this by multiplying 200 by 6 and setting it equal to 2.5 by x then solving for x, or you can find the rate the car travels in km in one hour. To do that, you divide 200 by 2.5 and get 80: this is your km per hour. Then you multiply that to 6 to see how far the car will go in 6 miles if it continues at the speed of 80 km per hour.

Answer:

Answer: 480 km

Step-by-step explanation:

As we know that if we keep speed or velocity constant, distance is directly proportional to time.

• In the first case:

[tex]{ \rm{d_{1} = kt _{1}}}[/tex]

• Substitute the variables with their respective values to find the value of constant, k

[tex]{ \rm{200 = (k \times 2.5)}} \\ \\ { \rm{k = \frac{200}{2.5} }} \\ \\ { \underline{ \rm{ \: \: k = 80 \: km {h}^{ - 1} \: \: }}}[/tex]

• In the second case

[tex]{ \rm{d _{2} = kt _{2} }}[/tex]

[tex]{ \rm{d _{2} = (80 \times 6)}} \\ \\ { \boxed{ \boxed{ \rm{ \: \: d _{2} = 480 \: km \: \: }}}}[/tex]

Since Inequality #1 was false, or not a solution, this shows that (1, 4) is not a solution.

Step-by-step explanation:

1)

[tex]11x+y<19\\y<19-11x\\[/tex]

2)

[tex]8x+3y<11\\3y<11-8x\\y<3\frac{2}{3}-2\frac{2}{3}[/tex]

Try Our Solutions:

1)

[tex]y<19-11x\\Substitute: (1, 4)\\4<19-11(1)\\4<19-11\\4<8\\False[/tex]

To solve that question we can think by the following way:

Using the fundamental principle of counting, we will find out that can be formed [tex]4\times 4 = 16[/tex] differents sequences (for example, AA, AG, TT, TG, CT...).

Know we know that, we can generalize. If I have [tex]n[/tex] elements and I must choose one of them [tex]t[/tex] times to do a sequence, the total number of sequence that I can form will be [tex]n^t[/tex].

In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is [tex]4\times 4\times 4\times ... \times 4[/tex] (29 times) [tex]= 4^{29}[/tex].

Therefore, there are [tex]4^{29}[/tex] DNA sequences with exactly 29 letters long.

Answer:

101.6

Step-by-step explanation:

The temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.

Given that,

The body temperature in Fahrenheit of a sheep is modeled by the equation,

[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]

where t is the number of hours.

Now, substitute t=3 into the equation;

[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]

[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]

Since, [tex]sin(\dfrac{\pi }{28} (- 6)) = - 0.5637[/tex]

Therefore, the temperature of the sheep when t=3 is:

[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]

[tex]T = 0.6 \times - 0.5637 + 101.6[/tex]

[tex]T = 101.24[/tex]

So, the temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.
