In a metal fabrication process, metal rods are produced to a specified target length of 15 feet. Suppose that the lengths are n

Leto [7]

Answer:

95% Confidence interval: (14.4537 ,15.1463)

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 15 feet

Sample mean, $\bar{x}$ = 14.8 feet

Sample size, n = 16

Alpha, α = 0.05

Sample standard deviation, σ = 0.65 feet

Degree of freedom = n - 1 = 15

95% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 15 and}~\alpha_{0.05} = \pm 2.1314$

$14.8 \pm 2.1314(\dfrac{0.65}{\sqrt{16}} ) \\\\= 14.8 \pm 0.3463 = (14.4537 ,15.1463)$

is the required confidence interval for the true mean length of rods.

The angles 3x+6 and 5x + 6 are supplements. What are the two angles

yarga [219]

Answer:

x = 21

Step-by-step explanation:

Step 1: Make an expression

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

Step 2: Combine like terms

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

Step 3: Subtract 12 from both sides

8x + 12 - 12 = 180 - 12

8x = 168

Step 4: Divide both sides by 8

8x / 8 = 168 / 8

x = 21

Answer: x = 21

Harold earns $10.50 per hour working at a doctor’s office. On Monday he spent 1 5/12 hours filing paper work, 1 3/4 sending emai

maks197457 [2]

Answer:$57.75

Step-by-step explanation:

Find the total amount of hours he worked

$1\frac{5}{12} +1\frac{3}{4} +2\frac{1}{3}\\\\\frac{17}{12}+ \frac{7}{4} +\frac{7}{3} \\\\\frac{17+21+28}{12} \\\\\frac{66}{12}=\frac{66/2}{12/2}=\frac{33/3}{6/3}= \frac{11}{2} or 5\frac{1}{2} or 5.5h$

So, he worked 5.5h and he earns $10.50 an hour.

($10.50)(5.5h)=$57.75
