A deck of cards has 52 cards with 4 suits (Hearts, Diamonds, Spades, and Clubs) and 13 cards in each suit (Ace thru 10, Jack, Queen, and King; the last three are considered face cards). A card is drawn at random from a standard 52-card deck. What is the probability that the card is not an Ace
Answer:
12/13
Step-by-step explanation:
P(card is not an Ace) =
(# of ways to not pick an ace) / (# of ways to pick a card from the deck) =
(52 - 4)/(52) =
48/52 =
12/13
What is 5.521 rounded to the nearest whole number?
Answer:
6
Step-by-step explanation:
If the first number (in this case, behind the decimal) is 5 or more, you round up. If it is 4 or less, you round down. since 2 and 1 are less than 4, you round down making them both 0. Then, you round up making the answer 6. I hope this makes sense! I wasn't entirely sure how to explain this.
w x and y are three integers w is 2 less than x y is 2 more than x prove that wy+ 4 =x^2
w + 2 = x
x + 2 = y
Cross multiply
y(w+2) = x(x+2)
wy + 2y = x^2 + 2x
make x the subject of the equation
x = y - 2
substitute this in place of (x) in 2x
wy + 2y = x^2 + 2(y-2)
wy + 2y = x^2 + 2y - 4
wy + 2y - 2y + 4 = x^2
wy + 4 = x^2

= 79,210
2. 6.231 * 10^3
10 ^ 3 is 1000
move the decimal point three places to the right
6,231
3. 0.234 * 10^2
10 ^ 2 is 100
move the decimal two places to the right
23.4
Cross multiply to determine whether the fractions are equivalent.
?
4/8=2/4
Answer:
16 = 16
Step-by-step explanation:
Cross multiplying is when you multiply the numerator and denominator of two fractions.
So, it would be 4 × 4 = 8 × 2 or 16 = 16. This is essentially proving they are equal to one another.

What is comparison of two numbers?
Comparison of two numbers, means to examine the differences between numbers, quantities or values to decide if it is greater than, smaller than or equal to another quantity.
According to the given question
We have a data in which
Number of people who liked action movie = 78
Number of people who liked action movie = 60
Number of people who disliked the action movie = 22
And, number of people who disliked the drama movie = 40
From the given data we conclude, that action movie is liked by more people as compared to drama movie because 78 > 60.
Hence, the action movie is better received by the audience than the drama.

.......................
Helpppppppppppppppppppppp!!!!!!! Plzzzzzzzzzzzzzzz
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180° so we can write
[tex]y + 2y + 3y = 180° \Rightarrow 6y = 180°[/tex]
Solving for y, we get
[tex]y = 30°[/tex]
So the other two angles of the triangle are
[tex]2y = 2(30°) = 60°[/tex]
and
[tex]3y = 3(30°) =90°[/tex]

Last year, the Galaxy Fair Amusement Park installed a family roller coaster they named The Twist. This coaster was designed to accommodate riders from age 4 to adult and features a tall climb hill and several banking turns. Overall, the park has been disappointed in the reception of The Twist, and very few families are riding the coaster this season. After some research, they discovered that park guests think the climb hill is too tall and fast for younger riders. Galaxy Fair Amusement Park has asked a roller coaster design firm to help them redesign The Twist during the coming off season. The quadratic function that represents the current climb hill is () = −0.102 + 3.6 − 2.4 and the quadratic function that represents the proposed redesign of the climb hill is () = −0.032 + 1.62 − 6.87. In these functions, the value of x represents the time, in seconds, since the roller coaster train cars have left the station, and the output variable is the height of the roller coaster track, in feet, above the ground. 1. Rewrite both () and () from standard form into vertex form. Explain your process. HINT: Each function has a common factor. Start by dividing it out. 2. State the vertex of each function. What does each vertex represent in context of The Twist? 3. Compare the a-value of () to the a-value of the parent quadratic function. What effect does this value have on a parabola? 4. Sketch both of the functions () and () on a single xy-plane. Describe the steps you took to create your sketch. 5. Use the vertex forms of () and () and the sketch you created in question 4 to describe the track changes that occur when the function that represents the climb hill is altered from () to (). Do you think these changes will help younger riders better enjoy The Twist? Explain.
