Answer:

\frac{5\pi }{6}\texttt{ radian =}150\texttt{ degrees}

Step-by-step explanation:

We know

            2π radians = 360 °

               1 radian = =\frac{360}{2\pi }=\frac{180}{\pi }

Here we are asked to convert \frac{5\pi }{6} radiands to degrees.

         \texttt{ 1 radian = }\frac{180}{\pi } \texttt{ degrees}\\\\\frac{5\pi }{6}\texttt{ radian =}\frac{5\pi }{6}\times \frac{180}{\pi } \texttt{ degrees}\\\\\frac{5\pi }{6}\texttt{ radian =}150\texttt{ degrees}

In a study relating the degree of warping, in mm, of a copper plate (y) to temperature in °C (x), the following summary statisti
elena-14-01-66 [18.8K]

Answer:

a)

y = 0.3035 + 0.0082x

b)

0.6315 mm

c)

x = 23.9634 °C

Step-by-step explanation:

a. Compute the least-squares line for predicting warping from temperature. Round the answers to four decimal places.

We need to find an equation of the form

y = b + mx

where m is the slope and b the Y-intercept.

The slope m can be computed with the formula

\bf m=\displaystyle\frac{\displaystyle\sum_{i=1}^n(x_i-\bar x)(y_i-\bar y)}{\displaystyle\sum_{i=1}^n(x_i-\bar x)^2}

Replacing the values in our formula (we will round at the end of the calculations)

\bf m=\displaystyle\frac{806.94}{98,775}=0.008169476

the Y-intercept b is computed with the formula

\bf b=\bar y-m\bar x

therefore we have

\bf b=0.5188-0.008169476*26.36=0.303452613

and the least-squares line rounded to 4 decimals would be

y = 0.3035 + 0.0082x

b. Predict the warping at a temperature of 40°C. Round the answer to three decimal places.

We simply replace x with 40 to get

y = 0.3035 + 0.0082*40 = 0.6315 mm

c. At what temperature will we predict the warping to be 0.5 mm? Round the answer to two decimal places

Here, we replace y with 0.5 and solve for x

0.5 = 0.3035 + 0.0082x ===> x = (0.5-0.3035)/0.0082 ===>

 

x = 23.9634 °C

Express the fractions 1/2, 3/16, and 7/8 with an LCD
Ket [755]
<span>Least Common Denominator (LCD) is the least number which all the denominators can divide without remainder. The given denominators are 2, 16 and 8. The least number 2, 16 and 8 will divide without remainder is 16. Therefore, to express the fractions 1/2, 3/12, and 7/8 with an LCD, we multiply both the numerator and the denominator of each of the fractions with a common factor that makes the denominator to be 16. Therefore, 1/2, 3/16 and 7/8 expressed with an LCD are (1 x 8) / (2 x 8), 3/16, (7 x 2) / (8 x 2) = 8/16, 3/16, and 14/16.</span>

Solve for x: −3|2x + 6| = −12
spayn [35]

Start with

-3|2x+6|=-12

Divide both sides by -3

|2x+6|=4

If the absolute value of a number is 4, that number can either be 4 or -4: we have the two solutions

2x+6=4 \iff 2x=-2 \iff x=-1

2x+6=-4 \iff 2x=-10 \iff x=-5
