Answer:
P(not 5, not 2) = 5/6 x 5/6 = 25/36
Step-by-step explanation:
Answer:
The correct answer is 5/6 bc
Step-by-step explanation:
The correct answer was 5/6
Let E be the event "the first die is a 5" and F be the event "the second die is a 2." E and F are independent events. Hence so are the complements of E and F. This means that the probability of the complement of E given the complement of F is just the probability of the complement of E, which is 1 - 1/6 = 5/6.

X=
Answer:
x = 4
Step-by-step explanation:
Given:
(√x + 2)(√x - 2) = 0
Required:
Find x
SOLUTION:
√x(√x - 2) + 2(√x - 2) = 0 (distributive property)
x - 2√x + 2√x - 4 = 0
x - 4 = 0
x - 4 + 4 = 0 + 4
x = 4

Sam has 6 boxes of pencils. Each pack has x pencils in it. After Julie gives Sam 4 more pencils, he has a total of 40 pencils.
40 - (x + 4) = 6
6(x + 4 ) = 40
6x + 4 = 40
6 + 4x = 40
Answer:
6x + 4 = 40
Step-by-step explanation:
6 boxes
x = number of pencils per box
therefore Sam had 6x and received 4 more
Answer:
6x + 4 = 40
explanation
Step-by-step explanation:
6 boxes
x = number of pencils per box
therefore Sam had 6x and received 4 more
et X represent the full height of a certain species of tree. Assume that X has a normal distribution with a mean of 191.8 ft and a standard deviation of 4 ft. A tree of this type grows in my backyard, and it stands 182.2 feet tall. Find the probability that the height of a randomly selected tree is as tall as mine or shorter.
Answer:
The probability that the height of a randomly selected tree is as tall as mine or shorter.
P(X≤182.2) = 0.0082
Step-by-step explanation:
Step(i):-
Mean of the Population = 191.8 ft
Standard deviation of the Population = 4 ft
Let 'X' be the random variable in normal distribution
X = 182.2 feet
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{182.2-191.8}{4} = -2.4[/tex]
Step(ii):-
The probability that the height of a randomly selected tree is as tall as mine or shorter.
P(X≤182.2) = P( z≤ -2.4)
= 1-P(z>2.4)
= 1-(0.5 + A(2.4))
= 0.5 - A(2.4)
= 0.5 - 0.4918
= 0.0082
The probability that the height of a randomly selected tree is as tall as mine or shorter.
P(X≤182.2) = 0.0082
Factor the expression completely.

Step-by-step explanation:
2x-3y= -14
5x+9y= -2
multiply the first one by 5 and the second one by -2 to get equal and opposite value of x.
➡️when you multiply,it will be
10x-15y= -70
-10x-18y= 4
cancel out each x value,then you get
-15y-18y= -70+4
-33y= -66, divide each side by -33 to get the value of y
⚪️y= 2
➡️substitute the value of y in the equation of (2x-3y= -14) to find the value of x
2x-3(2)= -14
2x-6= -14
2x= -14+6
2x= -8 divide both side by 2
⚪️x= -4
so the answer is (-4,2)

compare-and-contrast analysis of how culture shapes the heroes in Heart of a Samurai and Black Ships Before Troy. Use transition words in your draft to help clarify relationships of ideas. KWHL What do you know? What do you want to know? How will you learn? What have you learned?
Answer:
Culture has a significant impact on heroes. For starters, it influences how a person or character perceives a particular situation or idea, as well as their point of view on a variety of ideas and topics. Next, it has an impact on how the hero is portrayed in the story. Third, it influences how a character reacts to an idea or situation.
Culture has an impact on heroes. We see an example of this in 'Black Ships Before Troy,' where in Achilles' culture, to be a hero, you must be brave and fight. This is also evident in 'Heart of a Samurai,' where Manjiro's culture dictates that in order to be a hero, you must provide for your family.

Answer:
h(x) = -x² + 11 x + 2
Step-by-step explanation:
Explanation:-
Given that the functions are
f(x) = 2 x² - 5x -3
g(x) = x² + 6x -1
h(x) = g(x) - f(x)
= x² + 6x -1 - (2 x² - 5x -3)
= - x² + 6 x +5x -1+3
= -x² + 11 x + 2
h(x) = -x² + 11 x + 2
Final answer:-
h(x) = -x² + 11 x + 2

A cylinder has a base radius of 9m and a height of 14m. What is its volume in cubic m, to the nearest tenths place?
Please help
Answer:
3562.6 m³
Step-by-step explanation:
In this question, we have to find the volume of a cylinder.
The formula to find the volume of a cylinder is V = πr²h
Plug in your values and solve.
Solve:
V = π(9)²(14)
V = π(81)(14)
V = π(1,134)
V = 3562.566069
Round to the nearest tenths place.
V = 3562.6
Don't forget that the units for volume is already cubed, or to the power of 3.
Your final answer would be 3562.6 m³
