Answer:
on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.
Now
On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)
But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2
In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together
So our required answer is
p(even number)× p(tails)= 1/2 × 1/2 = 1/4

Name a possible value for n that is a solution to 15 < n, but not a solution to n < 25.
PLEASE EXPLAIN WHY ITS THAT ANSWER
Answers
Answer:
26
Step-by-step explanation:
The number has to be greater than 15 but not less than 25 so any number that is at least 25 works.
Answer:
It would just be at least 26. Because, it's saying that n has to be greater than 15 and greater than 25. so, that the n < 25 is wrong. So i would put 26 because 15 < (is less than) 26, and 26 <(less than) 25 is wrong which is required to be an answer. So you could do 26 through infinity.

$600 8% 1 year in simple interest
Answers
Answer:
$648.00 or you can say that you made $48 from simple interest
Step-by-step explanation:
Plug the numbers into the formula A = P(1 + rt) and solve,
First, convert to a decimal
r = R/100 = 8%/100 = 0.08 per year.
Solving the equation:
A = 600(1 + (0.08 × 1)) = 648
A = $648.00
Ruth is training for a half-marathon. On Saturday, she ran 3 miles in 34.5 minutes. On Sunday, she ran 2.5 miles in 28 minutes. How much faster, in minutes per mile, was her pace on Sunday than on Saturday?
Answers
Answer:
= 0.3 min/mile
Step-by-step explanation:

Sherry thinks 7, 7 and 12 are side lengths of a right triangle. Do you agree or disagree? Justify your reasoning. PLEASE NOW!!!! PLEASE!!!!!!
Answers
Answer:
disagree
Step-by-step explanation:
If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.
longest side = 12 ⇒ 12² = 144
7² + 7² = 49 + 49 = 98
Since 144 ≠ 98 then triangle is not right

Answer:
y=-x+6 is okay.
below it y=20-x
y-7x=6 -> y=7x+6
y+7x=8 -> y= -7x+8
3x+4y=12 -> y= -3x/4 + 12
6x+2y=6 -> y= -3x+3
Slope intercept is y=mx+b, Y can never be negative and it always will end up by itself.

One pair of corresponding sides of 2 similar triangles are 3 and 8 inches long, respectively. If the perimeter of the smaller triangle is 12 inches, what is the perimeter, in inches, of the larger triangle?
Answers
Answer:
Step-by-step explanation:
3 12
8
96 = 3x
x=32. the perimeter is 32
The perimeter of the larger triangle is 32 inches.
What are Similar Triangles?
Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
Let the perimeter of the larger triangle would be x.
We know that the ratio of the corresponding sides is 3/8.
The perimeter of the smaller triangle is 12 inches
We can use the ratio of corresponding sides to find the length of the sides of the larger triangle.
So 3/8 = 12/x
3x = 96
x = 96/3
x = 32
Thus, the perimeter of the larger triangle would be 32 inches.
