notka56 [123]

Answer: He should not be concerned

Step-by-step explanation:

The variation is still the same and has not changed because the only thing that changed are the units. A unit change does not mean that the diameter has changed, only the method of measuring it has changed.

Absolutely speaking, the diameter is still the same. A standard deviation of 0.1 inches is the same as a standard deviation of 2.54mm so the executive should not be worried.

What value of x is in the solution set of 3(x – 4) = 5x + 2?<br> -10

timurjin [86]

Answer:

x = - 7

Step-by-step explanation:

Given

3(x - 4) = 5x + 2 ← distribute left side

3x - 12 = 5x + 2 ( subtract 5x from both sides )

- 2x - 12 = 2 ( add 12 to both sides )

- 2x = 14 ( divide both sides by - 2 )

x = - 7

Crank

Given:

The graph of a line.

To find:

The equation of the line.

Solution:

From the given graph, it is clear that the line passes through the points (0,-2) and (-6,8). So, the equation of the line is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-(-2)=\dfrac{8-(-2)}{-6-0}(x-0)$

$y+2=\dfrac{10}{-6}x$

$y+2=-\dfrac{5}{3}x$

Subtract 2 from both sides.

$y=-\dfrac{5}{3}x-2$

Therefore, the equation of the line is $y=-\dfrac{5}{3}x-2$ .

In △ABC, m∠A=19°, a=13, and b=14. Find c to the nearest tenth.

34kurt

We know that
Applying the law of sines

step 1
Find the value of angle B
a=13
b=14
A=19°
so

$\frac{a}{sin A} = \frac{b}{sin B} \\ a*sin B=b*sin A \\ sin B= \frac{b}{a}*sin A \\ sin B= \frac{14}{13} *sin 19 \\ sin B=0.3506 \\ B=arc sin(0.3506) \\ B=20.5$ °

step 2
with angle A and angle B find the angle C
A+B+C=180-----> solve for C
C=180-(A+B)------> C=180-(19+20.5)-----> C=140.5°

step 3
$\frac{a}{sin A} = \frac{c}{sin C} \\ a*sin C=c*sin A \\ c=a* \frac{sin C}{sin A} \\ c=13* \frac{sin 140.5}{sin 19} \\ c=25.4$

the answer is
the value of c is 25.4
