A number X rounded to 2 decimal places is 7.42. Write down the error interval for X
Answer:
X = [7.415,7.419].
Step-by-step explanation:
The number is 7.42 so the thousandth place is from 5 to 9 and hundredth place is 1. i.e. 7.415, 7.416, 7.417, 7.418, 7.419. As 7.415 rounded to 2 decimal place is 7.42. The interval in x[7.415, 7.419].
Which alternative is the NEGATIVE reciprocal of -1/8?*
A-8
B. -1/8
C. 1/8
D. 8
Answer:
Reciprocal simply means... swap the denominator for the Numerator...
Now negative Reciprocal now means... Swap the denominator by the numerator and Multiply by -1
So
1/-8 becomes
-(-8/1)
=8.

Click or tap the graph to plot a point
The graph of the absolute value function can be seen at the end of the answer.
How to graph the absolute value function?For an absolute value function:
y = |x - a| + b
We need to start by graphing the vertex, which is the point (a, b).
Then, depending on the slope, we graph the arms.
In our case:
y = |x - 4| + 2
The slope is 1, so both the arms will open upwards with a 45° angle, and we can see that the vertex is (4, 2).

step and justification of root√3.5
[tex] \large \boxed{ \boxed{ \sqrt{3.5} }}[/tex]
In this case, we are going to use the 'Babylonian method to get the square root of any positive number.We must define an error for the final result.Say, less than 0.01. In other words, we will try to find the value of the square root to at least 1 correct decimal places.
Step 1:
Divide the number (3.5) by 2 to get the first guess for the square root. first guess = 3.5 / 2 = 1.75.Step 2:
Divide 3.5 by the result obtained in stepprevious. d = 3.5 / 1.75 = 2.Roll the arithmetic mean of (d) and the obtained valuein step 1: (2 +1.75) / 2 = 1.875 (newapproach).
Error = new guess - previous value = 1.75 1.875 = 0.125.0.125 0.01. As the error> accuracy, please repeat thist happened one more time.Step 3:
Divide 3.5 by the result obtained in the previous step. d = 3.5 / 1.875 = 1.8666666667.Roll the arithmetic mean of (d) and the value obtained in step 2: (1.8666666667 + 1.875) / 2 =1.8708333334 (new approximation).Error = new guess - previous value = 1.875 -1.8708333334 = 0.00416666660.0041666666 <0.01. Once the error <accuracy, stop the process and use 1.8708333334 as the final value for the square root.Then we can say that the square root of 3.5 is 1.87 with an error less than 0.01 (actually the error is 0.0041666666). This means that the first 2 decimal places are correct. Just for comparison, the returned value using the javascript function Math.sqrt (3.5) 'is 1.8708286933869707.Note: There are other ways to calculate square root. This is just one of them.

The triangle on the grid will be translated two units left. which shows the triangle translated 2 units left
Answer:
Take the coordinates of each vertex (corner point) and subtract 2 from the x-coordinate; leave the y-coordinate alone.
Step-by-step explanation:
Example: If one vertex is the point (5, 3), then it moves left 2 units to (3, 3).
If a vertex is at (-3, 1), then it moves 2 units left to (-5, 1).

Alyssa is trying to pick out an outfit for the first day of school. She can choose
from 4 pairs of pants, 8 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes.
How many different outfits does Alyssa have to choose from?
The number of different outfits is 1280
How to determine the number of different outfits?From the question, we have the following parameters that can be used in our computation:
8 pairs of pants, 6 t-shirts, 6 sweaters or hoodies, and 2 pairs of shoes
The number of different outfits is equal to the products of the count of each apparel.
This is represented as;
Different outfits = Pants * T-shirts * Sweaters or hoodies * Pairs of shoes
Substitute the known values in the above equation;
Different outfits = 4 x 8 x 8 x 5
Evaluate;
Different outfits = 1280
Hence, there are 1280 different outfits

Could someone please show me how to factor this using the x method
Answer:
(x + 2) (8x + 3)
Step-by-step explanation:
[tex]8x^{2}[/tex] + [tex]19x + 6[/tex]
= (x + 2) (8x + 3)
L = 3/a = 3/8
R = 16/a = 16/8 = 2
\ac/
L V R
/ \
/ b \
where letters have their usual meaning. Comparing 8x² + 19x + 6 to ax² + bx + c,
ac = 8*6 = 48
b = 19
Factors of ac or 48 :-
1 * 48
2 * 24
3 * 16
As the sum of 3 and 16 is 19(or b), our required pair is 3 and 16.
On the left side:
L = 3/a = 3/8
On the right side:
R = 16/a = 16/8 = 2
Therefore, factorized form is (x + 3/8)(x + 2) which can be written as (8x + 3)(x + 2).
How this method works:
Make a X with ac and b on the top and bottom of the X, where ac and b are taken from ax² + bx + c.
On the left side we have d/a and e/a. Basically d and e are those values that we get after solving the whole question.
Step1: find the pair(s) for which sum of factors of ac = b. Here it is 3 and 16.
Step2: put these values in place of d and e.
Step3: solve left anf right of X,
Left = d/a = 3/8
Right = e/a = 16/8 = 2
Step4: whatever you get, put that in (x+?)(x+?) in place of ?.
