Answer 1

Answer:

$40.59

$40.59

Step-by-step explanation:

Given the data below :

$19.99, $8.99, $35.99, $49.99, $49.99, $39.99, $99.99, $79.99, $35.99, $19.99, $49.99, $29.99, $49.99, $59.99, $35.99, $49.99, $19.99, $8.99, $29.99, $35.99

The mean of the sample data :

Σ(X) / n =

Σ(X) = $811.8

n = 20

Σ(X) / n = $811.8 / 20

Mean = $40.59

Frequency distribution:

Given:

To find:

The number of possible solutions, if the Order of Operations did not exist.

Solution:

We have,

[tex]4 + 9 + 16 \div 4 - 8 -3 \times  5[/tex]

Now,

Case 1:

[tex][4 + 9 + 16] \div [4 - 8 -(3 \times  5)]=29\div (4 - 8 -15)[/tex]

[tex]4 + 9 + 16 \div  4 - 8 -(3 \times  5)=-\dfrac{29}{19}[/tex]

Case 2:

[tex][4 + 9 + 16] \div  (4 - 8 -3) \times  5=29\div  (-7\times 5)[/tex]

[tex]4 + 9 + 16 \div  (4 - 8 -3) \times  5=-\dfrac{29}{35}[/tex]

Case 3:

[tex]4 + 9 + (16 \div 4) - 8 -(3 \times  5)=4+9+4-8-15[/tex]

[tex]4 + 9 + (16 \div 4) - 8 -(3 \times  5)=-6[/tex]

Many more possibilities are there.

Therefore, there are more than 3 possible solutions.

The finished inside diameter of the Piston ring is normally distributed with a mean of 4 inches and standard deviation of 0.01 inch. Below what value of inside diameter will 15% of the Piston ring fall

Answers

Answer:

3.98964 inches

Step-by-step explanation:

We are given;

Mean; μ = 4 inches

Standard deviation; σ = 0.01 inch

Probability = 15% = 0.15

Formula to calculate z-value is given by;

z = (X - μ)/σ

Now, since we are given the probability to be below 0.15,thus;

From z - table attached, the z value that corresponds to a probability of 0.15 is -1.036.

Thus, plugging in the relevant values into the z score equation gives;

-1.036 = (x - 4)/0.01

Cross multiply to give;

-0.01036 = x - 4

x = 4 - 0.01036

x = 3.98964 inches

Answer:

m<a = 30°

m<b = 90°

m<c = 60°

Step-by-step explanation:

Angles a, b, and c are all angles on a straight line.

Angles on a straight line add up to 180°.

Therefore, a + b + c = 180°

Given that a:b:c = 1:3:2, the measure of each can be calculated as follows:

Measure of each angle = the ratio proportion of that angle ÷ total ratio proportion * 180°

m<a = [tex] \frac{1}{6} * 180 = 30 [/tex]

m<b = [tex] \frac{3}{6} * 180 = 90 [/tex]

m<c = [tex] \frac{2}{6} * 180 = 60 [/tex]
