#1. a bag contains red marbles and white marbles in a ratio of 3 to 5. if one marble is drawn, what is the probability that the marble is not red?
#2. the sides of a triangle are 7in., 24in., and 25in. Is the triangle a right triangle? Justify your answer.
#3. The carpet cost $18 per square yard. Use two unit multipliers to find the cost per square foot.
#4. if the dimensions of a rectangle are increased by 100%, then the area of the rectangle is increased by what percent?
#5. The vertices of a trapezoid are at (-3,-2), (5,-2), )2,3), and (-2,3). What is the area of the trapezoide?
#6. √6 · √12
Answer:
#1: 5/8, #2: It is a right triangle, #3 $2: per square foot, #4: 300%
Step-by-step explanation:
#1: If you want the probability of drawing a non-red marble, you need to have the number of non-red marbles divided by the total number of marbles. Since it's a 3 to 5 ratio, and the 5 represents marbles that are white, not red, you can put 5/(5+3), or 5/8 as your answer.
#2: For this one, you need to use the pythagorean theorem, a rule that will be true if it's a right triangle, and false if it's not. It's A² + B² = C², where C is bigger than A and B. To apply this, you can plug 7² + 24² into a calculator, and see whether or not the answer is equal to 25² (which, in this case, it is, meaning that it is a right triangle.)
#3: The idea with this is cancelling out the units until you end up with the units you want. You know how 7897/7897 would still be equal to one, as anything divided by itself is still one? We can use that concept, because multiplying our original value by 1 won't change the value, just the units. Since 1 yard = 3 feet, we can do this: ($18)/(yard²) × (1 yard)/(3 feet) × (1 yard)/(3 feet) = $2/feet²
#4 This one I will use sample values for: let's say our rectangle has a length of 10 inches and a width of 20 inches. That means it's area will be L × W, that is, 10 × 20 = 200 inches². Now lets increase the dimensions by 100%. Our length would become 20 inches, and our width would become 40 inches. That makes L × W = 20 × 40 = 800 inches². Now, to see what percent increase that is from the original, we have to do (800 - 200)/200, that is, 3, or 300%.
Sorry I don't have time to do the last one, but might I suggest that you post the questions individually next time? I just think it might make people less scared to jump into solving one problem than five, so you might get answers sooner =)

A rectangle is placed around a semicircle as shown below. The length of the rectangle is 3 cm. Find the area if shaded region. Use the value 3.14 for pie, And do not round your answer.
Answer:
0.9675sq.cm
Step-by-step explanation:
Find a related diagram attached
Area of the shaded region = Area of rectangle - area of semicircle
Area of rectangle = 3cm * 1.5cm
Area of rectangle = 4.5sq.cm
Given
diameter of the semicircle = 3cm
area = πd²/8
Area of the semicircle = 3.14(3)²/8
Area of the semicircle = 3.5325sq.cm
Area of the shaded region = 4.5 - 3.5325
Area of the shaded region = 0.9675sq.cm

If his ship has been hit, dread pirate Michael will always miss. If the Captain and the pirate each shoot once, and the Captain shoots first, what is the probability that both the Captain and the pirate hit each other's ships?

The college dean obtains an alphabetical list of full-time students at her college and she selects the 26 names on that list and interviews those students to find them. Amount of student debt incurred by each of them. She uses the results to estimate the average (mean) amount of student debt incurred by college students in the united states. What type of sampling is used?
Answer:
The right approach is "Systematic sampling".
Step-by-step explanation:
Some kind of probabilistic sampling system where population or sampling units from some kind of broader group have been randomly chosen, although at a predetermined periodic interval, is termed as Systematic sampling.Where there would be a moderate possibility of information manipulation, it's indeed better to simply such samples.help needed asap will give brainliest

Answer:

The mixed fraction equations which are true are C , D and E
What are Mixed Numbers?A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
Let the mixed number equation be represented as A
Now , the value of A is
To solve each equation, we can convert mixed numbers to improper fractions, then multiply the fractions, and simplify the result if possible.
A)
A = 5/6 × 4 2/3 = (5/6) × (4×3 + 2)/3
A = (5/6) × 14/3 = 35/9, which is not equal to 3 8/9.
Therefore, equation A is false.
B)
B = 1 1/10 × 8 3/5 = (11/10) × (43/5)
B = 473/50 = 9 23/50, which is not equal to 9 1/2.
Therefore, equation B is false.
C)
C = 3 2/9 × 2 1/6 = (29/9) × (13/6)
C = 377/54 = 6 53/54
Therefore, equation C is true.
D)
D = 2 3/7 × 1 7/8 = (17/7) × (15/8)
D = 255/56 = 4 23/56 = 2 3/8
Therefore, equation D is true.
E)
E = 7/12 × 4 = 7/3 = 2 1/3
Therefore, equation E is true.
Hence , the equations that are true are C, D, and E

explain truth tables and how they work
A truth table is a way of organizing information to list out all possible scenarios. We title the first column p for proposition. In the second column we apply the operator to p, in this case it's ~p (read: not p). So as you can see if our premise begins as True and we negate it, we obtain False, and vice versa.
