Answer:
d) 1/5
Step-by-step explanation:
5(x + 1) - 8 = 5x(2-4)
5x+5-8 = 5x(-2)
5x-3=-10x
15x = 3
x = 1/5
Answer:
d. 1/5Step-by-step explanation:
5(x + 1) - 8 = 5x(2-4)
=> 5x + 5 - 8 = 10x - 20x
=> 5x + 20x - 10x = 8 - 5
=> 15x = 3
[tex] = > x = \frac{3}{15} [/tex]
=> x = 1/5 (option d) (Ans)
A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 116.4-cm and a standard deviation of 0.8-cm. For shipment, 29 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is less than 116-cm.
Answer:
Calculate lengths from each of the lengths (116.4 & 0.8), using the well known formula z = (x-μ) / σ.
Look up the Probabilities associated with those two lengths
Subtract the lesser probability from greater of these two probabilities, to get probability 0.8 in the associated interval.

x + 5y + 5z = -10
x + y +z= 2
x + 2y + 3z = -3
Answer:
(5, -1, -2)Step-by-step explanation:
Given system:
x + 5y + 5z = -10 x + y + z = 2 x + 2y + 3z = -3Eliminate one of the variables.
Subtract the second equation from the first and from the third equation:
x + 5y + 5z - x - y - z = -10 - 2 ⇒ 4y + 4z = -12 ⇒ y + z = -3x + 2y + 3z - x - y - z = -3 - 2 ⇒ y + 2z = -5Now subtract the first equation above from the second to solve for z:
y + 2z - y - z = -5 + 3z = -2Find y:
y + z = -3y - 2 = -3y = 2 - 3y = -1Now find x:
x + y + z = 2x - 1 - 2 = 2x - 3 = 2x = 2 + 3x = 5The solution is:
(5, -1, -2)Compare negative square root of 7 and -3.12345
Answer: Square root of negative 7 is greater than -3.12345
Step-by-step explanation: Since the square root of -7= 2.64575131 i (A positive number) Then it's greater, since the positive number is always greater than the negative numbers, because the negative numbers are further below zero than the positive number, if there is a number below the zero and a number above the zero, the one above the zero is greater, because it's a positive number, the one below 0 is negative.

Supplementary angles are two angles that add up to 180 degrees! * Angles A and Care supplementary. Find the measure of angle C.HELPP
Answer:
106
Step-by-step explanation:
a=74
c=?
180-74=106
============================================================
Explanation:
As the hint states at the top, supplementary angles add to 180 degrees
If we glued the angles together, then we'd form a straight line.
angleA+angleC = 180
74+C = 180
C = 180-74
C = 106 degrees

3³+11-10÷2×4=w
Answer:
18
Brainliest, please!
Step-by-step explanation:
3^3 + 11 - 10 / 2 x 4 = w
27 + 11 - 10 / 2 x 4 = w
27 + 11 - 5 x 4 = w
27 + 11 - 20 = w
38 - 20 = w
w = 18
Which of the following describes 977.834? Select all the that apply
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
977.834 can be defined as a rational number. Why? Well, 977.834 is not a non-terminating non-recurring/recurring number. Of it was, then it would have been an irrational number. Now, it can be a real number also because real numbers include all sorts of numbers whether it be fractions, decimals, roots, cubes etc. It's not an integer because integers don't include decimals or fractions numbers. So, the answers or options that are correct are

Swing an arc that intersects the arc created from line BC at point C.
Mark the intersection of the two arcs as point G.
Draw a line through point C and point G.
Answer:
Step-by-step explanation:
As it is impossible to understand who have done what ,
the correct construction should be :
You are given point A, point B and point C.
Construct a line parallel to that line AB passing through point C.
1) Place the compass on point B, and swing an arc that crosses line AB and line BC.
Label the points D and E.
2) Keep the compass at the same width, and place it on point C.
3) Swing an arc that crosses line BC, and label the point F outside the segment [BC] .
4) Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
5) Swing an arc that intersects the arc created from line BC at point C.
6) Mark the intersection of the two arcs as point G.
7) Draw a line through point C and point G.
You just have to discover who has done that.

The data set and some summary statistics are listed.
11.5, 12.3, 13.5, 15.6, 16.7, 17.2, 18.4, 19, 19.5, 21.5
Mean: 16.52
Median: 16.95
Standard Deviation: 3.11
IQR:5.5
How does adding 5 to each of the values in the data set impact the measures of variability?
Answer:
see below:
Step-by-step explanation:
the median will become a larger, different number. The mean will also become a larger number, since it will still be dividing by the same amount of numbers in the equation, only the quantity will become larger. Same with standard deviation. The IQR will change, because the amount of the two numbers you'll be subtracting will end up greater than before.

Answer:
TU = 29
Step-by-step explanation:
TU + UV = TV , substitute values
9x + 2 + 5 = 14x - 8 , that is
9x + 7 = 14x - 8 ( subtract 14x from both sides )
- 5x + 7 = - 8 ( subtract 7 from both sides )
- 5x = - 15 ( divide both sides by - 5 )
x = 3
Then
TU = 9x + 2 = 9(3) + 2 = 27 + 2 = 29

If f(n) = 3n+ 5 , find f(-3). soln, 3n+ 5
Answer: f(-3) = -4
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given expression
f(n) = 3n + 5
Substitute values into the expression
f(-3) = 3(-3) + 5
Simplify by multiplication
f(-3) = -9 + 5
Simplify by addition
f(-3) = [tex]\boxed{-4}[/tex]

please help me will mark braniliest
Answer:
The correct answer is option A. Line DB
Step-by-step explanation:
When you write that M is a line, the sign for this would be a line with arrows on both of its end like this : <------------>
Now, due to the fact that lines look like this <------------>, we can cross out option C and D as they both aren't lines but points. Points go like this: ---->
Option B says, "line EB", this can't be true because E corresponds with the letter F, it can't become a line with B hence why the only option true here is choice A.
