How can you solve an equation with the variable on both sides plz help

1 answer:

7 0

I don't know if this is the right one but i hope this helps. this is how i learned it.
step 1=get variables on one side oof the equal sign by using inverse operation (add or subtract smaller variable)
step 2= get constants away from variable to the other side of the equal sign by using inverse operations (add or subtract constant)
step 3: isolate the variable using inverse operation (multiply or divide)

What are the two ordered pairs for 5x=-1

jonny [76]

5x = -1

x = -1/5 = -0.2

That means that any ordered pair for the line will be (-0.2, y)

You can put any number in for y.

So two ordered pairs could be:

(-0.2, 1)
and
(-0.2, 2)

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is r

svp [43]

Answer:

0.1 = 10% probability that the class length is between 51.5 and 51.7 min, that is, P(51.5 < X < 51.7) = 0.1.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min.

This means that $a = 50, b = 52$

If one such class is randomly selected, find the probability that the class length is between 51.5 and 51.7 min.

$P(51.5 \leq X \leq 51.7) = \frac{51.7 - 51.5}{52 - 50} = \frac{0.2}{2} = 0.1$

0.1 = 10% probability that the class length is between 51.5 and 51.7 min, that is, P(51.5 < X < 51.7) = 0.1.

1.94x - 10/8x + 4.32 = [2(1.15x+8.5)]

kipiarov [429]

$1,94x-\frac{10}{8}x+4,32=[2(1,15x+8,5)]\\\\
1,94x-1,25x+4,32=2,3x+17\\\\
0,69x+4,32=2,3x+17\ \ \ |Subtract\ 2,3x\\\\
-1,61x+4,32=17\ \ \ |Subtract\ 4,32\\\\
-1,61x=12,68\ \ \ |Divide\ by\ -1,61\\\\\boxed{x\approx7,9}

If Professor Wilson found that the test scores of his students had a variance of 4.4, what is the standard deviation? Type a num

malfutka [58]

Answer:

The standard deviation will be: 2.1

Step-by-step explanation:

We know that standard deviation is basically the square root of variance.

Using the formula to calculate the standard deviation

$s=\sqrt{s^2}$

The variance = s² = 4.4

so the standard deviation can be calculated as:

standard deviation $=\sqrt{s^2}$

$=\sqrt{\left(4.4\right)^}$

$=2.1$

Therefore, the standard deviation will be: 2.1

See below for the terms, coefficients, and constants in the variable expressions

<h3>How to determine the terms, coefficients, and constants in the variable expressions?</h3>

To determine the terms, coefficients, and constants, we use the following instance:

ax + by + c

Where the variables are x and y

Then the terms are ax, by and c
The coefficients are a and b
The constant is c

Using the above as guide, we have:

A) 2b + 2ac+5

Terms: 2b, 2ac, 5
Coefficient: 2, 2 and 5
Constant 5

B) 34abx + 16y +1

Terms: 34abx, 16y, 1
Coefficient: 34ab, 16
Constant: 1

C) st +4u + v

Terms: st, 4u, v
Coefficient: 4

D) 14xy + 6

Terms: 14xy, 6
Coefficient: 14, 6
Constant 6

E) 14x + 12y

Terms: 14x, 12y
Coefficient: 14, 12

F) 3+ 6-7+a

Terms: 3, 6, -7, a
Coefficient: 1
Constant: 3, 6, -7
