"a" varies directly as the square of "b" and inversely as the cube of "c". If a=171 when b=8 and c=9, find a if b=9 and c=6. Round your answer to two decimal places if necessary.

Answers

Answer:

a = 730.43

Step-by-step explanation:

The formula for this type of problem is [ a = kb²/c³ ].

We are given a = 171, b = 8 and c = 9.

Solve for k.

171 = k(8)²/(9)³

k = 1947.80

Solve for a since we found k using b = 9 and c = 6.

a = (1947.80)(9)²/6³

a = 730.425

Round to the nearest hundredth.

730.425 → 730.43

Best of Luck!

Answer:

730.42

Step-by-step explanation:

a varies directly with the square of b, and inversely with the cube of c.  Therefore:

a = k b² / c³

where k is the constant of proportionality.

a = 171 when b = 8 and c = 9.  So the value of k is:

171 = k (8)² / (9)³

k ≈ 1947.8

So the value of a when b = 9 and c = 6 is:

a = 1947.8 (9)² / (6)³

a ≈ 730.42

A line with a slope of -10 passes through the point (1,-10) what is it equation in slope intercept form?

Answers

Answer:

y=-10x

Step-by-step explanation:

m=-10

For (1,-10) a=1  AND  b=-10

(use the formula y-b=m(x-a) to find the equation of the line)

y-b=m(x-a)

(sub the values of m (the slope) and a&b (from the point)

y - (-10) = (-10) × ( x - 1 )

(simplify)

y+10=-10(x-1)

(expand the bracket)

y+10=-10x+10

(subtract 10 for both sides)

y=-10x+10-10

(simplify)

y=-10x

The local garden store sells bags of mulch for $4.98 each and will deliver the bags for a fee of $15 if Amber purchases 15 bags and has them delivered what is the total amount that Amber will pay?

Answers

Answer:

$89.70

Step-by-step explanation:

To solve this equation, let's formulate a linear equation.

Let [tex]b[/tex] equal bags of mulch.

Let [tex]t[/tex] equal the total amount.

We know the price of each bag of mulch ($4.98), so we can represent this as:

[tex]4.98b[/tex]

We also know that there's a fee of $15, so we can just represent this as:

[tex]15[/tex]

Let's put these values into an equation:

[tex]t=4.98b+15[/tex]

Now with an equation, we know that she purchases a total of 15 bags, so let's substitute [tex]15[/tex] for [tex]b[/tex]:

[tex]t=4.98(15)+15[/tex]

Multiply:

[tex]t=74.70+15[/tex]

Add:

[tex]t=89.70[/tex]

_

Check your work by substituting the total amount into the initial equation:

[tex]89.70=4.98b+15[/tex]

Subtract [tex]15[/tex] from both sides of the equation:

[tex]74.70=4.98b[/tex]

Divide both sides of the equation by the coefficient of [tex]b[/tex], which is [tex]4.98[/tex]:

[tex]15=b[/tex]

Amber did in fact purchase 15 bags, so we know our total amount is correct!

y - 5 = 1/10 (x – 10)

A primatologist believes that rhesus monkeys possess curiosity. She reasons that, if this is true, then they should prefer novel stimulation to repetitive stimulation. An experiment is conducted in which 12 rhesus monkeys are randomly selected from the university colony and taught to press two bars. Pressing bar 1 always produces the same sound, whereas bar 2 produces a novel sound each time it is pressed. After learning to press the bars, the monkeys are tested for 15 minutes, during which they have free access to both bars. The number of presses on each bar during the 15 minutes is recorded. The resulting data are as follows:What is the alternative hypothesis? In this case, assume a nondirectional hypothesis is appropriate because there is insufficient empirical basis to warrant a directional hypothesis. What is the null hypothesis?

We will use t test for unpaired
