Keith is a drummer who purchases his drumsticks online. When practicing with the newest pair, he notices they feel heavier than
Marina86 [1]

Answer: 0.0174

Step-by-step explanation:

Given : \mu=1.85\ \ ; \sigma=0.18

Let x be the random variable that represents  the weight of the drumsticks.

We assume that the weight of the drumsticks is normally distributed.

Now, the z-score for x=2.23 ,\because z=\dfrac{x-\mu}{\sigma}

\Rightarrow\ z=\dfrac{2.23-1.85}{0.18}\approx2.11\ \ \

Using z-value table , we have

P-value =P(x≥2.23)=P(z≥2.11)=1-P(z<2.11)=1-0.9825708

=0.0174292≈0.0174 [Rounded nearest 4 decimal places]

Hence, the  probability of the stick's weight being 2.23 oz or greater = 0.0174

Answer:

C

Step-by-step explanation:

Miami rainfall:  1.61 +2.24 +2.99 +3.15 +5.35 + 9.68 = 25.02

Tampa rainfall: 2.24 +2.8 +3.03 + 2.05 + 2.09 + 6.69 = 18.9

25.02 - 18.9 = 6.12

Miami gets more rainfall by 6.12 more inches

A table of values of a linear function is shown below. Find the output when the input is n . Type your answer in the space provi
amid [387]

Answer:

5; -22

Step-by-step explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional.

Given the following data;

Input: 1 2 3 4 n

Output: -10 -13 -16 -19

For an input variable of 1, 2, 3, 4; the output variable is -10, -13, -16, -19 respectively.

To find the value of n;

We can deduce that the input is increasing by a value of 1.

Thus, n = 4 + 1 = 5

For the output;

We can deduce that the output is increasing by a value of -3.

Thus, the next output = -19 + (-3) = -22
