Answer:
El período paleolítico corresponde a [tex]\frac{332}{333}[/tex] de la época prehistórica.
Step-by-step explanation:
En primer lugar, se determina la extensión de tiempo, medida en años, tanto de la época prehistórica como el período paleolítico: (Nótese que el signo negativo significa a.C.)
Época Prehistórica
[tex]\Delta T = -2500-(-2500000)[/tex]
[tex]\Delta T = 2497500\,years[/tex]
Período Paleolítico
[tex]\Delta t = -10000 - (-2500000)[/tex]
[tex]\Delta t = 2490000\,years[/tex]
La fracción de la época prehistórica que corresponde al período paleolítico es:
[tex]r = \frac{\Delta t}{\Delta T}[/tex]
[tex]r = \frac{2490000\,years}{2497500\,years}[/tex]
[tex]r = \frac{332}{333}[/tex]
El período paleolítico corresponde a [tex]\frac{332}{333}[/tex] de la época prehistórica.

hope that will help you.
Answer:
x = −15
Step-by-step explanation:
x−2x = 2x+15−2x
−x = 15
−x/−1 = 15/−1
x = −15
Jacob needs 48 ounces of tomatoes for the spaghetti sauce he is choosing between the two brands shown explain how Jacob can determine which is the better value
Answer:Jacob could compare the unit rates of cost per ounce. The unit rate that is less per ounce is the better deal. Not He can look at the cost per ounces!
Im late but hope this helps anyone doing makeup work!
Brand A costs $0.37 or 37 cents per ounce and Brand B costs $0.31 or 31 cents per ounce.
We need to find the unit rate for each brand. Round to the nearest cent (hundredth).
What are ounces?The definition of an ounce is 1/16 of a pound or a very small amount of something.
According to column 1, 8 ounces of tomatoes would cost 2 dollars and 99 cents. So, the cost of one ounce of tomatoes can be calculated as follows.
When the cost of one ounce of tomatoes is rounded off to the nearest cent, it can be written as $0.37.
According to column 2, 16 ounces of tomatoes would cost 4 dollars and 99 cents. So, the cost of one ounce of tomatoes can be calculated as follows.
When the cost of one ounce of tomatoes is rounded off to the nearest cent, it can be written as $0.31.
Therefore, Brand A costs $0.37 or 37 cents per ounce and Brand B costs $0.31 or 31 cents per ounce.

18=3(3x-6) multi step equation
Answer:
x=4
Step-by-step explanation:
18=3(3x-6)
Divide each side by 3
18/3=3/3(3x-6)
6 = 3x-6
Add 6 to each side
6+6 = 3x-6+6
12 = 3x
Divide by 3
12/3 = 3x/3

I need to find f(-2) in this graph however I don't know please help me
======================================================
Explanation:
Check out the diagram below. Locate -2 on the horizontal x axis. Draw a vertical line through this value. Mark where the vertical line crosses the curve. Call this point P. Then draw a horizontal line through point P to have it cross the y axis. This horizontal line crosses at y = 1
In short, x = -2 leads to y = 1
So that is why f(-2) = 1
This is another way of saying f(x) = 1 when x = -2.
Note: y = f(x) since both are outputs of a function
Point N is on line segment MO. Given MO = 3x - 10, NO = x, and M N = 8,
determine the numerical length of MO.
Answer:
MO = 17
Step-by-step explanation:
First, you need to define what if the unknown x.
segment MN and NO are equal to MO.
thus, your equation for the combination is x +8
Now set the values equal to each other
x + 8 = 3x - 10 (subtract x from both sides)
8 = 2x - 10 ( get your x value alone, add 10 to both sides)
18 = 2x (simplfy)
x = 9
Now plug x value into MO
3 (9) - 10 = 17
Check with opposing equation:
9 + 8 = 17 √
A basketball player makes 60% of his free throws. We set him on the line of free-throw and informed him to shoot free throws until he misses. Let the random variable X be the number of free throws taken by the player until he misses. Assuming that his shots are independent, find the probability that he will miss the shot on his 6th throw. Show work detail please
a) 0.04666
b) 0.03110
c) 0.01866
d) 0.00614
Answer:
B. 0.03110
Step-by-step explanation:
Given
Probability of Hit = 60%
Required
Determine the probability that he misses at 6th throw
Represent Probability of Hit with P
[tex]P = 60\%[/tex]
Convert to decimal
[tex]P = 0,6[/tex]
Next; Determine the Probability of Miss (q)
Opposite probabilities add up to 1;
So,
[tex]p + q = 1[/tex]
[tex]q = 1 - p[/tex]
Substitute 0.6 for p
[tex]q = 1 - 0.6[/tex]
[tex]q = 0.4[/tex]
Next,is to determine the required probability;
Since, he's expected to miss the 6th throw, the probability is:
[tex]Probability = p^5 * q[/tex]
[tex]Probability = 0.6^5 * 0.4[/tex]
[tex]Probability = 0.031104[/tex]
Hence;
Option B answers the question

b) 0.03110

Expand the expression (x-5)^3
Answer:
[tex]x^3[/tex]-15[tex]x^{2}[/tex]+25x-125
Step-by-step explanation:
This is a quadratic equation, so we need to open the equation first. There are three (x-5), and then we multiply them together, and then combine like terms to get the answer.
(x-5)(x-5)(x-5)=
[x(x-5)-5(x-5)](x-5)=
([tex]x^{2}[/tex]-5x-5x+25)(x-5)=

Write the set of real numbers between 110 and 220 in interval notation.
Answer:
[tex]110\geq x \leq 220[/tex]
Step-by-step explanation:
Given
Minimum: 110
Maximum = 220
Required
Write as interval notation
Let the real numbers be represented with x
We start by setting x greater than or equal to the minimum:
[tex]x \geq 110[/tex]
Then, we set x less than or equal to the maximum:
[tex]x \leq 220[/tex]
Write out both inequalities
[tex]x \geq 110[/tex] and [tex]x \leq 220[/tex]
This can be rewritten as:
[tex]110 \geq x[/tex] and [tex]x \leq 220[/tex]
Both inequalities can be merged to give:
[tex]110\geq x \leq 220[/tex]
Answer:
(110,220)

Describe the translation of Point A (3, -8) to A'(-4,-5).
Answer:
left 7 and up 13
Step-by-step explanation:
The translation path of Point A (3, -8) to A'(-4,-5) exists 3 units down and 7 units to the left.
What is meant by translation?A translation in mathematics does not turn, but rather moves a shape left, right, up, or down. Congruent translations are those in which the translated shapes (or the image) seem to be the same size as the source ones. Just one or more directions have they shifted.
Each point in a figure is moved by the same amount and in the same direction during a translation, a type of transformation.
With a sort of transformation called translation, every point in a figure is moved the same distance in the same direction.
The translation path of Point A (3, -8) to A'(-4,-5) exists 3 units down and 7 units to the left.
