A coin is tossed then a letter from the word INCREDIBLE is chosen at rndom What is thr probablility of getting heads then a vowel?
Answer: 1/5
Step-by-step explanation: the probability that you get heads on the coin is 1/2 and the probability for getting a vowel out of incredible is 4/10 or simplified 2/5. So you multiply... 1/2 x 2/5 = 1/5
Kelly's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 4 single-shot espressos and 6 double-shot espressos. What percentage of the espressos sold were single-shot?
Answer:
40% of espresso was single-shot.
Step-by-step explanation:
To make a percentage, you need to think of a fraction first. The denominator is always 100 in a percent. If my answer is 40%, the fraction would be 40/100. If there was 6 double shots and 4 single shots, those two together would make 10. 10 x 10 is 100. So really, you just have to multiply 4 by 10 to get the percentage.

Step-by-step explanation:
Nicole is half as old as Donald. The sum of their ages is 72.
How old is Nicole, in years?
Answer:
24 years
Step-by-step explanation:
let Donald's age be x
then Nicole's age would be 1/2 * x = x/2
now, x + x/2 = 72
3x/2 = 72
3x = 72*2
x = 144/3 = 48
Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.

In this experiment, you will be using two different coins as a simulation for a real-world compound event.
Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.
What is the theoretical probability that the family has two dogs or two cats?
Describe how to use two different coins to simulate which two pets the family has.
Flip both coins 50 times and record your data in a table like the one below.
Result Frequency
Heads, Heads
Heads, Tails
Tails, Heads
Tails, Tails
Total 50
Based on your data, what is the experimental probability that the family has two dogs or two cats?
If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
How could you change the simulation to generate data for three pets?
Answer:
see below <3 i hope this helps!
Step-by-step explanation:
What is the theoretical probability that the family has two dogs or two cats? (1/2)
The choices are dd, dc, cd, cc
There are 4 choices = dd or cc/ total = 2/4 = 1/2
Let the heads of the coin be dogs and the tails of a coin be cats
Flip two coins and coin A is the first pet and coin B is the second pet
heads , heads = 10
heads, tails 14
tails heads =13
tails tails = 13
total 50
Experimental probability 2 dogs or 2 cats = ( hh, tt) /total = ( 10+13) /50 = 23/50
If we had 3 pets
what is the theoretical probability that they have three dogs or three cats?
ddd, ddc, dcd, dcc, ccc, ccd ,cdc, cdd
There are 8 options
ddd or ccc/ total = 2/8 = 1/4
Let the heads of the coin be dogs and the tails of a coin be cats
Flip three coins and coin A is the first pet and coin B is the second pet Coin C be the third pet. ///////////// Did this help? :3 If so please give brainliest bc this took a while to type

Answer: For the first one, 12.5% chance
Step-by-step explanation:
The probability of flipping a coin and getting tails is 50%. Then, if you were to flip two coins and get both tails, you would have to divide the 50% by 2, which is equals to 25% of flipping two coins and getting them both tails.
So now we know...
Flipping one coin gives you 50% tails and 25% of flipping two coins and getting two tails
So now, we do it again with the third coin. We would divide the 25% by 2, which will get us to a 12.5% of getting all tails, or in fractions, 1/8

one - third the difference between 3/4 and 1/5
11/60 will be the one - third the difference between 3/4 and 1/5.
What is simplification?
When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one way for promoting consistency in job effort, cost, and duration. It removes diversity and variation that is harmful, meaningless, or superfluous.
Given, two fractions 3/4 and 1/5
Difference between these two fractions = 3/4 - 1/5
Difference between these two fractions = 15/20 - 4/20
Difference between these two fractions = 11/20
One-third of the difference = [tex]\frac{11}{20} * \frac{1}{3}[/tex] = 11*60
Therefore, The one-third difference between 3/4 and 1/5 will be 11/60.

Find the missing angle in a triangle with the given sides.
Answer: 72 degree
Step-by-step explanation:
By Angle Sum Property,

''Create your own word problem where the answer is ⅝. It should be solved using multiplication''
Answer:
Hi, your answer will be 5/8 x 2/8.
Step-by-step explanation:
When multiplying fractions, you are to do both the numerators and denominators. So, if you do 5/8 x 2/8, that would result as 10/16. When you simplify, that would be 10/16 divided by 2, which is 5/8.

On Tuesday,Fairbanks, Alaska had a temperature of -3 degrees and Sanford had a temperature of 42 degrees. What is the difference in the two temperatures?
Answer:
45 degrees
Step-by-step explanation:
42 degrees is 42 “points” away from zero (picture a number line). -3 degrees is 3 points away from zero on the number line, but in the opposite direction. The two numbers are 45 “points” away from each other.
When they say find the difference, it’s a subtraction equation.
42 - (-3) = 42 + 3 = 45
A scalene triangle has an angle that measures 47∘ and a second angle that measures 88∘. What is the measure of the third angle?
Answer:
45°
Step-by-step explanation:
The angles of any triangle add up to 180 degrees
add the two known angles: 47+88=135
then subtract the sum from 180 to get answer: 180-135=45
Answer:
45
Step-by-step explanation:
In a triangle the angles add up to 180 degrees. So, we can subtract 47 and 88 from 180. The result, 45, will be your final answer.

Did any get the answer for puzzle 3 in Pythagorean Theorem Digital Escape!
The formula relations given by Pythagorean theorem is used to
determine the lengths and area of the given squares and triangles.
Responses:
1. Area of a is H: 25
2. Length of b is I: 5
3. Length of C is A: 7.94
4. Area of d is B: 35.73
Where can the Pythagorean theorem be used to find the lengths and areas of a figure?1. Given;
The area of the side squares are; 9 m² and 16 m²
According to Pythagorean theorem, we have;
Area of square a = 9 m² + 16 m² = 25 m²
Area of a is H: 252. b² = Area of side square a
Therefore;
b = √(25 m²) = 5 m
Length of b is I: 53. Given;
Area of the squares adjacent to the hypotenuse side and a leg are;
144 m² and 81 m² respectively
According to Pythagorean theorem, we have;
C² = 144 m² - 81 m² = 63 m²
C = √(63 m²) = √(9 × 7 m²) = 3·√7 m ≈ 7.94 m
Length of C is A: 7.944. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m
Area of d is B: 35.73Learn more about Pythagorean theorem here:

find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x
16x + 8
10x + 4
12x + 4
8x + 2
Answer:
12x+4
Step-by-step explanation:
To find the perimeter of any shape you just have to take the sum of all the sides.
In this case you would write:
4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)
Now you just have to simplify the expression which would give you:
12x+4 (after collecting like terms)
So the final answer will be 12x+4
