Nataliya [291]

Answer:

When is at a significance level of 0.0001, the concentration of lead is above in water from Minnesota.

Step-by-step explanation:

The Significance level is the calculation or estimation of the strength of proof that must be seen in a sample, before the hypothesis will be rejected and concluded that the result is statistically true or correct.

In this case, when a data is calculated to be significant at 0.0001 from a recent duty, what the significance level implies in this case is that, at  a level of 0.001, the concentration of lead is above or higher in water from Minnesota.

Tim is selling tickets to a school sporting event to raise money for his club. He put some extra money in his box before he bega
mihalych1998 [28]
The price of each ticket will be the slope found from the data.  

Slope=m=(y2-y1)/(x2-x1)=(177.5-146.25)/(18-13)

m=6.25  (so the cost of the tickets is $6.25)

Now we can use any data point to solve for b, or the y-intercept of the line:

y=6.25x+b, using (177.5, 18)

177.5=6.25(18)+b

b=$65.00d

So he started with $65.00

The number 4 is the smallest positive integer that has exactly three factors: 1, 2, and 4. If k is the next-highest integer that
saul85 [17]

To solve this problem, we must do a method of trial and error to find for the next highest integer with exactly three factors. We know that the value of k must be greater than 4, therefore by using trial and error to find for the correct answer:

 

Factors of 5:1, 5

Factors of 6:1, 2, 3, 6

Factors of 7:1, 7

Factors of 8:1, 2, 4, 8

Factors of 9:1, 3, 9

 

Therefore we stop at 9 since this is already our answer. It has exactly three factors.

The sum of the factors is:

sum of factors = 1 + 3 + 9

<span>sum of factors = 13</span>
