Help please? i would really appreciate it.
raketka [301]

Answer:

The answer is option C i.e; y=0.9x-45

Step-by-step explanation:

When you substitute the values of x you have to get same values as given in the table

For example: substitute x=50 in the equation y=0.9x-45

Y= 0.9(50)-45

Y= 45-45

Y=0

A true-false quiz with 10 questions was given to a statistics class. Following is the probability distribution for the score of
mart [117]

Solution

Question 1:

- The formula for finding the mean score is that of the expected value formula. That is,

\begin{gathered} E(x)=\sum_{i=1}p_i\times x_i \\ where, \\ p=\text{ The probability of getting a score of }x\text{ } \\ x=\text{ The actual score} \end{gathered}

- Thus, the mean can be gotten as follows:

\begin{gathered} \sum px=5\left(0.06\right)+6\left(0.16\right)+7\left(0.34\right)+8\left(0.23\right)+9\left(0.15\right)+10(0.06) \\ =7.43 \end{gathered}

The mean score is 7.43

Question 2:

- The more students write the exam, the more the mean score will approach the theoretical mean score.

- The theoretical mean score is calculated above to be 7.43

- Thus, as more students write the quiz, their scores approach 7.43

The length of a rectangle is increased by 10 percent the width of a rectangle is increased by 5 find the percentage increased in
aalyn [17]

Answer: The percentage increase in perimeter is 7%.

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

The original length of the rectangle is 20 and the original width is 30. The original perimeter of the rectangle would be

Perimeter = 2(20 + 30) = 100

The length of the rectangle is increased by 10 percent. It means that the new length would be

20 + (0.1 × 20) = 22

The width of the rectangle is increased by 5 percent. It means that the new width would be

30 + (0.05 × 30) = 31.5

The new perimeter of the rectangle would be

Perimeter = 2(22 + 31.5) = 107

The increase in perimeter is

107 - 100 = 7

The percentage increase in perimeter is

7/100 × 100 = 7%
