Jake heard that spinning—rather than flipping—a penny raises the probability above 50\%50%50, percent that the penny lands showi

ng heads. He tests this by spinning 101010 different pennies 101010 times each, so he's willing to treat these spins as a random sample. In his 100100100 spins, the penny landed showing "heads" in 686868 spins. He wants to use these results to test H_0: p=0.50H

Jonathan works at an advertising agency. When he was hired, he was given four days of paid vacation time. For each year that he
sleet_krkn [62]

a) The number of paid vacation days that Jonathan gets at the end of five years of employment is <u>19 days</u>.

b) The model of the relationship between x, the number of years Jonathan has worked, and y, the number of paid vacation days earned, is <u>y = 4 +3x</u>.

c) Jonathan will reach the maximum number of paid vacation days allowable in 8 years.

<h3>Data and Calculations:</h3>

Initial paid vacation time for the first year = 4 days

Additional paid vacation time for an additional year = 3 days

Number of paid vacation time after 5 years = 19 days (4 + 3 x 5)

Number of years worked = x

Number of paid vacation days earned = y

Model of the relationship between x and y is <u>y = 4 +3x</u>.

If y = 28 days

x = (28 - 4)/3

x = 24/3

x = 8 years

Thus, the model of the relationship between x and y is <u>y = 4 +3x</u>.

How many positive four-digit integers are multiples of 5 and less than 4,000
Volgvan

Answer:

  Number of positive four-digit integers which are multiples of 5 and less than 4,000 = 600

Explanation:

 Lowest four digit positive integer = 1000

 Highest four digit positive integer less than 4000 = 3999

 We know that multiples of 5 end with 0 or 5 in their last digit.

 So, lowest four digit positive integer which is a multiple of 5 = 1000

 Highest four digit positive integer less than 4000 which is a multiple of 5  = 3995.

 So, the numbers goes like,

       1000, 1005, 1010 .....................................................3990, 3995

 These numbers are in arithmetic progression, so we have first term = 1000 and common difference = 5 and nth term(An) = 3995, we need to find n.

          An = a + (n-1)d  

           3995 = 1000 + (n-1)x 5

           (n-1) x 5 = 2995

           (n-1) = 599

            n = 600

 So, number of positive four-digit integers which are multiples of 5 and less than 4,000 = 600
