Solve this k/3+4-2k=-9k

Mathematics

o-na [289]3 years ago
3 0
K/3 + 4 -2k = -9k
First you add 9k to both sides
<span>k/3 + 4 -2k = -9k
</span>            +9k   +9k
<span>k/3 + 4 + 7k = 0
</span>
Now subtract 4 from both sides
k/3 + 4 + 7<span>k = 0
</span>        -4           -4
k/3 + 7<span>k = -4
</span>
Now multiply 3 by both sides
k/3 + 7<span>k = -4
</span>x3     x3    x3
k +21k = -12

Now add k + 21k
22k = -12

Now divide both sides by 22
<span>22k = -12
</span>-----    -----
 22      22
k = -6/11

write an equation in slope intercept form for the line that passes through the point, and is perpendicular to the line y=-1/3x+9
aleksklad [387]

Answer:

Step-by-step explanation:

y=-1/3x+9

This is written in the format y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).

Perpendicular lines have a slope that is the negative inverse of the slope of the reference line, in this case -(1/3).  The new slope is 3.  equation is:

y = 3x + b

To find b, enter the given point, (-6,-2) and solve for b:

y = 3x + b

-2 = 3(-6) + b

-2 = -18 + b

b = 16

The full equation is y=3x + 18

Write two decimals one repeating and one terminating with the values between 0 and 1
weqwewe [10]

A repeating decimal is one that essentially goes on forever. A terminating decimal is one that has an end, therefore a definite value.

The fraction 1/3 is a repeating decimal, because when you divide 1 by 3, you get .333333 (to infinity). To show that something is repeating, draw a bar (or line) above the number that is repeating, in this case, 3.

The fraction 1/4 is a terminating decimal. Like the one above, when you divide 1 by 4, you get a fraction. In this case, it is .25, which does not repeat.

The fractions are there just to show you how you could get to either, but your terminating decimal is .25, and your repeating decimal is .3 (but with a line over the 3 if possible).

Determine whether or not the procedure described below results in a binomial distribution. If it is not​ binomial, identify at l
ArbitrLikvidat [17]

Answer:

a) it is not a binomial, it is hypergeometric distribution.

Step-by-step explanation:

a) Four hundred different voters in a region with two major political​ parties, A and​ B, are randomly selected from the population of 3000 registered voters.

it is not a binomial because the probability of succes changes between one trial and another one, so the trials are not independent.
