Answer:
The perfect square ( x -1 )² = 2
Step-by-step explanation:
Explanation:-
Given equation x² - 2 x = 1
⇒ x² - 2 x + 1 -1 = 1
⇒ x² - 2x + 1² = 1 +1
⇒ ( x -1 )² = 2
Mrs.Giblin begins hiking at mile marker 25 on the Appalachian Trail and hikes 3 miles every hour. What is the slope?
Answer:
3 miles
Step-by-step explanation:
Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles
This is the change in miles / change in time.
Chang in miles = 3
Change in time = 1
Slope = 3/1
Slope = 3

Step-by-step explanation:
its 42° because its smaller than 48° and that's the only option smaller lol
Answer:
42 degrees
Step-by-step explanation:
The angle forms a right angle, which in total would be 90 degrees.
48 + 42 would be the only option because it is the only one that adds up to 90 degrees.

(-5,13) and (1,1)
(-5,14)and (12,-21)
(1,1)and(12,-21)
Answer:
1.) -2
2.) -2
3.) -3
Step-by-step explanation:
Since we can't make a graph, we can make a table
(-5,13) and (1,1)
x y
-5 13
1 1
From 13 to 1, you subtract 12 ( y-section)
From -5 to 1, you add 6 (x-section)
Now we can do y/x
y/x = 12/6 = -2
The slope for this first one is (-2).
(-5,14) and (12,-21)
x y
-5 14
12 -21
From 14 to -21, you subtract 34
From -5 to 12, you add 17
Now we can do y/x
y/x = -34/17 = -2
The slope for this second one is (-2)
(1,1 )and (12,-21)
x y
1 12
12 -21
From 12 to 21, you subtract 33
From 1 to 12, you add 11
Now we can do y/x
y/x = -33/11 = -3
The slope for this third one is (-3)

A jar is filled with pennies, nickels, and dimes. The probability of picking a penny is 1/4, and the probability of picking a dime is 1/3. What is the probability of picking a nickel? Write your answer as a decimal rounded to the hundredths place.
Answer:
What Are The Options?
Step-by-step explanation:
Answer:
0.42
Step-by-step explanation:
given:
P (penny) = 1/4
P (dime) = 1/3
since the only other possibility is to pick a nickel, hence
P (nickel)
= 1 - 1/4 - 1/3
= 5/12
= 0.4166667
= 0.42 (nearest hundredth)
In a certain board game, a 12-sided number cube showing numbers 1–12 is rolled. If 4 such number cubes are rolled, what is the probability that at least 1 number cube will show a number 8 or larger?
The probability that at least 1 number cube will show a number 8 or larger is 0.83.
What is a binomial distribution in probability?In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability (commonly called a binomial experiment). The binomial probability is
[tex]n^C_xp^xq^{n - x}.[/tex]
Given, In a certain board game, a 12-sided number cube showing numbers 1 to 12 is rolled.
So, Numbers that are 8 or larger is 8, 9, 10, 11, 12.
Now, The probability(p) of getting a number 8 or larger P(X ≥ 8) = 5/12.
hence q = 1 - p = 7/12.
Therefore, If 4 such cubes rolled the probability that at least 1 number cube will show a number 8 or larger is,
P(X≥ 8) = [tex]^4C_1(\frac{5}{12})(\frac{7}{12})^4+^4C_2(\frac{5}{12})^2(\frac{7}{12})^2+^4C_3(\frac{5}{12}^3)(\frac{7}{12})^1+^4C_4(\frac{5}{12})^4(\frac{7}{12})^0[/tex].
P(X≥ 8) = 4(0.41×0.115) + 6(0.173×0.34) + 4(0.072×0.58) + 1(0.030×1).
P(X≥ 8) = 0.283 + 0.35 + 0.167 + 0.030.
P(X≥ 8) = 0.83 or 83% chance.

Step-by-step explanation:
Tanner is picking three varieties of apples at an orchard: Gala, Fuji, and Jazz. Each type of apple has a different cost per pound. He knows that 1 pound of each apple variety would cost a total of $5.16, and that the cost per pound of Jazz apples is the same as the combined cost per pound of the Gala and Fuji apples. Tanner picks 12 pounds of apples, including 3 pounds of Gala and 5 pounds of Fuji, for a total cost of $21.24.
If g represents the cost per pound of Gala apples, f the cost per pound of Fuji apples, and j the cost per pound of Jazz apples, which system of equations represents this situation?
Answer:
2g + 2f = 5.16
7g + 9f = 21.24
Step-by-step explanation:
Let
Gala = g ; Fuji = f ; jazz = j
g + f + j = 5.16 - - - (1)
j = g + f - - - (2)
From (1):
g + f + g + f = 5.16
2g + 2f = 5.16 - - - (3)
Total pound picked by Tanner = 12
3 Pounds of g ; 5 pounds of f
j = 12 - (5 +3) = 4 pounds
3g + 5f + 4j = 21.24 - - - (4)
3g + 5f + 4(g + f) = 21.24
3g + 5f + 4g + 4f = 21.24
7g + 9f = 21.24 - - - - - (5)

Find the length AB ?
Answer:
AB = 54
Step-by-step explanation:
DE is a midsegment of the triangle and is half of AB , that is
2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction
4x + 26 = 13x - 37 ( subtract 13x from both sides )
- 9x + 26 = - 37 ( subtract 26 from both sides )
- 9x = - 63 ( divide both sides by - 9 )
x = 7
Thus
AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54

Division
The division allows us to divide or 'share' numbers to find the answer to a problem.
For example, to evenly share 10 sweets between 5 kids, we use division to find 10/5 = 2 sweets per kid.
It's given a high school football stadium has 3,892 seats distributed in 14 sections and each section has the same number of seats.
To find the number of seats in each section we use division:
3,892 seats / 14 sections = 278 seats per section
