Mathematics
1 answer:
vlada-n [284]3 years ago
7 0

Answer:

Step-by-step explanation:

Given sequence is -5, -1, -5, -25,..

In any arithmetic series  nth term is given by  a + (n-1)d

where a is the first term

and d is the common difference.

 d = nth term - (n-1)th term

For the given  series

a = -5

lets take nth term as 2nd term and 1st term as (n-1)th term

d = -1-(-5)= -1+5 = 84

n th term = a + (n-1)d

using the formula for nth term

4th term = 5 + (4-1)8 = 29

An after-school sewing club has 120 yards of fabric to divide equally among the members of the club. When two more students join
maksim [4K]

The number of members before the entry of two new participants was 6, because before they had 20 yards and after their entry each one had 15 yards.

<h3>How to calculate how many members there were?</h3>

To figure out how many members there were, we must try different numbers until we find which number matches the information. In this case, it can be affirmed that there were 6 members, that is to say that each one had 20 yards.

  • 120 ÷ 6 = 20 yards.

Now, knowing that 2 more members joined, we must divide 120 by 8 to check the information in the statement.

  • 120 ÷ 8 = 15

According to the above, the number of members at the beginning was 6.

Explain how the complement can be used to find the probability of getting at least one item of a particular type
valkas [14]
The outcome A="At least one" means {1,2,3,4,5......n}   where n is the maximum possible outcome.

The only other outcome (B) left (i.e. the complement of the above event "at least one") is (B)={0}.

Therefore, by Kolmogorov's second axiom, A and B are complements, and
P(A)+P(B)=1
therefore
P(A)=1-P(B), or in words,
Probability of outcomes of "at least one" is the complement of the outcome of "0" item.

Tara and Ashley spent the same amount at the grocery store. Tara bought 5 pounds of apples. Ashley bought 3 pounds of apples and
alexandr402 [8]

Answer:

one pound of apple cost $2.5

Step-by-step explanation:

Let the amount they both spent at the grocery store be y and x be the price of apples per pound.

Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).

Equating both expressions, 5x = 3x + 5

collecting like terms,

5x - 3x = 5

2x = 5

dividing both sides by 2, we have

x = 5/2

x = 2.5

So one pound of apple cost $2.5
