Answer:

$13,450

Step-by-step explanation:

The fixed costs of production, are the costs incurred that are independent from the production volume, that is, regardless of how many spinners the company produces, those costs will remain the same. If 'x' is the number of spinners produced, interpreting the cost function, we can see that it costs $1.28 to produce each spinner and that there is a cost that does not rely on production of $13,450. Therefore, the fixed cost of production is $13,450.

Please explain, too! Thank you :)

Answer:

∠POS = 128°

Step-by-step explanation:

Angles on a straight line always add up to 180°

Therefore:

∠POS + ∠POQ = 180° (as they are the angles on line SOQ)

∠POS + 52° = 180°

∠POS = 180° - 52°

∠POS = 128°

Answer:

y = 4x +5

Slope is 4

Intercept is 5

Step-by-step explanation:

Using, y1= 1 and x1= -1

And, y2 = 13, x2 = 2

$\frac{y2 - y1}{x2 - x1} = \frac{y - y1}{x - x1}$

$\frac{13 - 1}{2 - ( - 1)} = \frac{y - 1}{x - ( - 1)}$

$\frac{12}{3} = \frac{y - 1}{x + 1}$

$4 = \frac{y - 1}{x + 1}$

$y - 1 = 4(x + 1)$

y-1 = 4x +4

y = 4x +4 +1 = 4x +5

What is the degree measure of x in this triangle?

Crank

So this is trig, and when it comes to right (90°) triangles, it's imperative that you know:
SOH-CAH-TOA

Sine (x) = Opposite/Hypotenuse
Cosine (x) = Adjacent/Hypotenuse
Tangent (x) = Opposite/Adjacent

*hypotenuse is always the largest side, and the one opposite the 90° angle in right triangles

therefore we'll use SOH, because the opposite of x (O) and the hypotenuse (H) are given:

Sine (x) = Opposite/Hypotenuse
Sine (x) = 32/58 = 16/29 = 0.552
Sine (x) = 0.552
now we use something called arc-sine, or
${(sin)}^{ - 1}$
it's basically a fancy function of most advanced calculators, so we'll plug it in as:
$x = {(sin)}^{ - 1} (0.552)$
x = 33.49° --> answer B) is correct

Why is t distribution better than normal distribution?

scoray [572]

You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.
