we can suggest this equation:
2x+4=35
Now, we solve this equation:
2x+4=35
2x=35-4
2x=31
x=31/2
x=15.5
Answer: the equation will be: 2x+4=35, and the weight of one checked bag will be 15.5 g,
Answer:
15.5
Step-by-step explanation:
2w+ 4 = 35 is the equation
15.5 is the total for w

x ≠ 2, 7
Interval Notation:
2 ≠ x ≠ 7
Final answer:
Algebraically, 'x is not equal to 2 and x is not equal to 7' is written as x≠2 and x≠7. In Interval Notation, it is written as (-∞, 2) U (2, 7) U (7, ∞). The given conditions exclude the numbers 2 and 7 from the entire real number line.
Explanation:
In the field of Mathematics, if you want to express the condition 'x is not equal to 2 and x is not equal to 7' algebraically, you write it as x≠2 and x≠7. In Interval Notation, you'd denote this as (-∞, 2) U (2, 7) U (7, ∞). This is read as 'x is all real numbers except 2 and 7' because we have excluded these two numbers from the entire real number line.

The recursive function which represents the number of stamps he has on any day in the future is F(n) = 80 + 2ⁿ.
Given that:
Number of stamps that Nathan has in the beginning = 80
He adds 1 stamp to it today.
Each day he plans to add twice the number of stamps as the previous day.
So, the number of stamps will be in the order:
80 + 1, 80 + 2(1), 80 + 2(2(1)), 80 + 2(2(2(1))), ...
That is each day, the added stamps become twice.
On the first day, he added 1, on the second day, he added 2, on the third day, he added 4, ...
So, the recursive function can be written as:
F(n) = 80 + 2ⁿ, where n starts from 0.

We start with 80 and we add 1 on the first day, 2 on the 2nd, 4 on the 3rd, etc.. Looking at the numbers being added 1 = 202 = 214 = 228 = 2316 = 24...We start with 80 and we add 2n to it where n represents the number of days into the iterationwith n starting at 0 The function that shows how many stamps we have on any given day is DS = 80 + ∑ 2n Where D is the number of days we are into the iteration n=0NOTE: This starts at day 0 which would be S = 80 + 20 = 80 + 1 = 81 stamps Example: To find how many stamps we have on D = 4 we would haveS = 80+20+21+22+23+24 = 80+1+2+4+ 8+16 = 111 stamps

Answer:
0.0288 = 2.88%
Step-by-step explanation:
First we need to know that in one standard deck of 52 cards we have 13 ace cards, 13 spade cards, and 4 four cards.
If we want a combination of ace, spade and four, we calculate the probability of each one, and then multiply them all:
The probability of getting an ace is 13/52 = 1/4
The probability of getting a spade is 13/52 = 1/4
The probability of getting a four is 4/52 = 1/13
As the order of our three cards doesn't matter, we have 3! (factorial of three) = 6 different ways of having a group of ace, spade and four, so our total probability will be multiplied by 6.
So, our probability is:
(1/4) * (1/4) * (1/13) * 6 = 6/208 = 3/104 = 0.0288 = 2.88%
Answer:
Probability = 0.23
Step-by-step explanation:
Probability of picking it choosen those at random without replacement =Pr(ace) + Pr(spade)+Pr(a four)
Probability = 4/52 + 4/52 + 4/52
Probability= 3(4/52)
Probability = 0.23
