The probabilities include:
a) 1/3. b) 1/3. c) 1/6.a) 1/11. b) 1/11.a) 5/144 b) 1/36 c) 153/780a) 6/65 b) 32/195 c) 153/7801/128.24/49.13/144.1/128.How to determine probability?1a) To find the probability of adding both times, use the formula: P(A and B) = P(A) × P(B)
There are 6 possible outcomes for each roll, so the sample space for rolling a die twice is 6 × 6 = 36.
There are 6 ways to get a sum of 7:
Each of these outcomes has probability 1/36, so the probability of getting a sum of 7 is 6/36 = 1/6.
Therefore, P(add both times) = P(sum of 7 or 8) = P(sum of 7) + P(sum of 8) = 1/6 + 1/6 = 1/3.
b) To find the probability of rolling an even number less than 5;
There are 2 even numbers less than 5: 2 and 4.
Each of these outcomes has probability 1/6, so the probability of rolling an even number less than 5 is 2/6 = 1/3.
c) To find the probability of getting the same number both times;
There are 6 possible outcomes where the same number is rolled both times: (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), and (6, 6). Each of these outcomes has probability 1/36, so the probability of getting the same number both times is 6/36 = 1/6.
2a) The probability of getting heads on the first toss is 1/2. The probability of selecting a P from INDIANAPOLIS is 2/11 (since there are 2 P's in the word and 11 letters total). Therefore, P(heads, then P) = P(heads) × P(P) = 1/2 × 2/11 = 1/11.
b) The probability of getting tails on the first toss is 1/2. The probability of selecting an N from INDIANAPOLIS is 2/11 (since there are 2 N's in the word and 11 letters total). Therefore, P(tails, then N) = P(tails) × P(N) = 1/2 × 2/11 = 1/11.
3a) P(red, then yellow) = P(red) x P(yellow) = (10/24) x (2/24) = 5/144
b) P(both blue) = P(blue) x P(blue) = (4/24) x (4/24) = 1/36
c) P(both dimes) = P(dime) x P(dime) = (18/40) x (17/39) = 153/780
4a) P(penny, then dime) = P(penny) x P(dime) = (8/40) x (18/39) = 36/390 = 6/65
b) P(silver coin, then penny) = 2 x (P(quarter) x P(penny) + P(dime) x P(penny) + P(nickel) x P(penny)) = 2 x [(4/40) x (8/39) + (18/40) x (8/39) + (10/40) x (8/39)] = 64/390 = 32/195
c) P(both dimes) = P(dime) x P(dime without replacement) = (18/40) x (17/39) = 153/780
5. The probability of getting heads on a single toss of a fair coin is 1/2. Since each coin toss is independent, the probability of getting heads on seven tosses in a row is (1/2)⁷ = 1/128.
6. The probability that both Kevin and Mike make their next putts is the product of their individual probabilities: (16/21) x (9/14) = 48/98 = 24/49.
7. The probability that it does not snow on Monday is 1 - 8/9 = 1/9. The probability that it does not snow on Tuesday is 1 - 3/16 = 13/16. Since the events are independent, the probability that it does not snow on either day is (1/9) x (13/16) = 13/144.
8. The probability of guessing a multiple choice question correctly is 1/4 and the probability of guessing a true-false question correctly is 1/2. Since each question is independent, the probability of guessing all five answers correctly is (1/4)² x (1/2)³ = 1/128.

Answer:
y = 1x + 7
Step-by-step explanation:
The equation formula for this scenario is y = mx + b
m = slope
b = y-intercept
To find the slope, pick two points. I picked (2,9) and (4,11).
Subtract 11 from 9, you'll get 2.
Subtract 4 from 2, you'll get 2.
2/2 equals 1. The slope (m) = 1
To find the b, y-intercept, plot the points on a graph and see if the linear line across the y-intercept. For this case, the y-intercept is 7.
The equation is: y = 1x + 7
what does -2x + 9 look like on a graph?
Answer:
The line of the graph will be going down 2/1 and will pass through the y intercept at 9.

If 5 friends each had one part of a scarf that's 1 and 5/12 yards long what fraction of the scarf could each friend knit
Answer:
17/60 yards of scarf
Step-by-step explanation:
If 5 friends each had one part of a scarf that's 1 and 5/12 yards long what fraction of the scarf could each friend knit
To solve the above question:
5 friends = 1 5/12 yards
1 friend = x yards
Cross Multiply
5 × x = 1 × 1 5/12 yards
x = 17/12 yards ÷ 5
x = 17/12 yards × 1/5
x = 17/60 yards of scarf

Parallelogram 3 length: 20 in. width: 21 in. diagonal: 29 in. Parallelogram 4 length: 18 in. width: 20 in. diagonal: 26 in. James put the parallelograms together so one vertex from each paper exists on a point, as shown in the circle. 4 parallelograms are put together so that one vertex from each paper exists on a point. Which statement explains whether or not the parallelgrams can be put together so each occupies one-quarter of the area of the circle without overlapping any other pieces? Check all that apply.
Answer:
B. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles.

Daniel want to know the volume of his cube, he notices the the cube has 1/5 centimeters side length, what is the volume of the cube?
Answer: 1/125cm³
Step-by-step explanation:
The volume of a cube is gotten by multiplying the side length given by itself thrice.
Since the cube in the question has a side length of 1/5cm, the volume of the cube will be:
= 1/5 × 1/5 × 1/5
= 1/125cm³
Therefore, the volume of the cube is 1/125cm³

The perimeter of a rectangular atrium is 300 yards. The length of the garden is ninety-six yards more than the width. Find the length and the width
Answer:The perimeter of a rectangular atrium is 27 yards in width and 123 yards in length.
Step-by-step explanation:
Step 1
The perimeter of a rectangular atrium is given as 2( l+b)
The perimeter of a rectangular atrium is 300 yards.
Let the width be represented as x
such that the
The length of the garden which is ninety-six yards more than the width is expressed as x+ 96
and the expression to solve for length and width will now be
Step 2
Perimeter = 2(l+b) = 2l + 2b
300=2( x+96) + 2 x
300= 2x+ 192 + 2x
300= 192+ 4x
300-192=4x
108=4x
x=108/4
x=27
width = 27 yards
length = x+ 96= 27 +96=123 yards

A wildlife photographer photographs a crocodile and then paddles against a river current for 6 km. Then, hoping to photograph a hippopotamus, she paddles 15 km across a lake. She paddles across the lake for one hour longer than she paddled up the river. Find the speed of the boat as she paddles the lake if the river current is 2 km/h.
Answer:
5 or 6
Step-by-step explanation:
So I did it in a different way than shown in rsm classes. I said that the speed was x-2 and x.
then I said the distance was 6 and 15. If the time taken was 1 hour more, then we can come up with this equation:
Since the time is 6/x-2 or 15/x
15/x-6/x-2=1
multiply everything to get a common denominator then cancel it out to get
(15x-30)-6x=x^2-2x
11x-30=x^2
x^2-11x+30=0
(x-5)(x-6) is factored form.
so x=5 or x=6. this means that the speed of the boat is either 5km/h or 6 km/h
solve for x solve for x

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-3,1), m= 7
Answer:
y=7x+22
Step-by-step explanation:
the equation of a line is y=mx+b
we know that 7 is m so
y=7x+b
but we got to find b
so we use the point (-3,1) and substitute in our equation
1=7(-3)+b
lets find b
1= -21+b
22=b
okay then we found b now lets go to our original problem and substitute b
y=7x+22

Mary drove from her home to the library after she left the library she drove to the park after that she drove home the map shows the past you took how far did Mary Drive?
Answer:
24 miles
Step-by-step explanation:
Distance formula (d):
D = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
Home to library
(-4, 1) ; (-4, 9)
D1 = sqrt((-4 + 4)^2 + (9 - 1)^2)
D1 = 8
Library to park :
(-4, 9) ; (2, 1)
D1 = sqrt((2 + 4)^2 + (1 - 9)^2)
D3 = 10
Park to home :
(2, 1) ; (-4, 1)
D1 = sqrt((-4 - 2)^2 + (1 - 1)^2)
D2 = 6

Johnny is standing on a platform 12 meters high throw ball up velocity 11 meters what time will ball hit the ground after 2 seconds
Answer:
The ball will hit the ground after 1.54 seconds
Step-by-step explanation:
This is a form of projectile motion in horizontal direction
Thus, time taken to reach the ground
[tex]t = \sqrt{\frac{2*d}{g} }[/tex]
Substituting the given values in above equation, we get -
[tex]t = \sqrt{\frac{2* 12}{10} } \\t = 1.54[/tex]seconds
The naturalist found 9 bright blue poisonous frogs in South America. Each frog weighed 3 grams. In all, how much did the 9 frogs weigh? A) 39 grams in all B) 27 grams in all C) 12 grams in all D) 36 grams in all
Answer: B) 27 grams in all
Step-by-step explanation:
Given: The weight of each bright blue poisonous frog = 3 grams
By using the multiplication operator (x)
Then, the weight of 9 such frogs = 9 x (Weight of each frog)
⇒ The weight of 9 frogs = 9 x 3 grams
⇒ The weight of 9 frogs = 7 grams
Therefore, the correct option is B) 27 grams in all
