Wich expression defines the given series for seven terms? 8+13+18+.......

Answers

Answer 1

Answer:

Answer: a+6d will defines the series for seven terms i.e. 38.

Step-by-step explanation:

Since we have given that

$8+13+18+......$

Here, a = first term = 8

d = common difference is given by

$a_2-a_1\n\n=13-8\n\n=5$

So, we need to find the seven terms:

So, here n = 7

So, it becomes,

$a_7=a+(n-1)d\n\na_7=8+(7-1)5\n\na_7=8+6* 5\n\na_7=8+30\n\na_7=38$

Hence, a+6d will defines the series for seven terms i.e. 38.

Answer 2

Answer: you're just adding 5
example
8+5= 13
13+5=18
18+5=23
23+5=28
28+5=33
and so on :)

Betty sets up a lemonade stand and charges $1 per glass. It cost her $50 to set up the stand. Which function gives the profit, p, she makes by selling g glasses of lemonade? The number of glasses of lemonade, g, that Betty needs to sell to make a profit, p, if the setup cost her $50 is given by the function . f(g) = .

Answers

If you would like to find the function that gives the profit Betty makes by selling a number of glasses of lemonade, you can find this using the following steps:

p ... profit
g ... glasses of lemonade

f(g) = p = g * $1 - $50

The correct result would be f(g) = g * $1 - $50.

Answer with explanation:

Amount charged to Betty for Lemonade Stand = $ 50

Amount charged by Betty for a glass of Lemonade= $ 1

Variable , P is used to denote Profit.

Variable, g , is used to denote number of glasses of Lemonade Sold.

If Betty wants to make a profit, then

→ g (Number of glasses of lemonade Sold) > 50

⇒Profit (P)=[Number of glasses of Lemonade Sold (g)>50]×$ 1 -$50

→ P=g -50, where, g >50,that is a positive integer,greater than 50.

Set up Cost , of $ 50 is represented by the function , f(g).

So, the above function changes to

→ P = g - f(g)

After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?

Answers

Final answer:

The appropriate hypotheses for the engineer's hypothesis test on the proportion of households without power are the null hypothesis that the proportion is 19%, and the alternative hypothesis that the proportion is greater than 19%.

Explanation:

The appropriate hypotheses for the engineer's hypothesis test on the proportion of households without power after the tropical storm would be:

Null Hypothesis (H0): The proportion of all households without power is 19%.
Alternative Hypothesis (Ha): The proportion of all households without power is greater than 19%.

The engineer will collect data and perform the hypothesis test to determine if there is sufficient evidence to conclude that the estimate is too low.
