Answer:

2069 grams

Step-by-step explanation:

Assume that the box itself is massless so the weight is only due to the spheres only. Calculate the volume of a solid sphere of radius 3 in:

Vout = (4/3)pi(3^3) = 36pi in^3

Now calculate the volume of a solid sphere of radius 2 in:

Vin = (4/3)pi(2^3) = (32/3)pi in^3

To calculate the volume of the hollow sphere, subtract Vin from Vout:

Vnet = Vout - Vin = (76/3)pi

Since the density of the plastic is 3.25 g/in^3, the mass of each hollow sphere is

m = (density) × Vnet = (3.25 g/in^3)×(76/3)pi

= 258.7 g

Since there are 8 spheres in a box, the total weight of the box is

M = 8m = 2069 grams

Answer:

[tex](a)\ c(x) = 39 + 0.09 x[/tex]

[tex](b)\ \$53.4[/tex]

Step-by-step explanation:

Given

[tex]Base\ Charge = \$39[/tex]

[tex]Rate = 0.09[/tex] per mile

Solving (a): Linear Equation

The total charges (c(x)) is: the base charge + the rate * number of miles (x).

So, we have:

[tex]c(x)= 39 + 0.09 * x[/tex]

[tex]c(x) = 39 + 0.09 x[/tex]

Solving (b): Cost of rent, if miles = 160

This implies that x = 160

So, we have:

[tex]c(x) = 39 + 0.09 x[/tex]

[tex]c(160) = 39 + 0.09 *160[/tex]

[tex]c(160) = 39 + 14.4[/tex]

[tex]c(160) = 53.4[/tex]

Answer:

There are two correct answers:

A. [tex]\sqrt{(-2-7)^{2} +(8-13)^{2} }[/tex]

E. [tex]\sqrt{(7+2)^{2} +(13-8)^{2} }[/tex]

Step-by-step explanation:

The formula for the distance between two points is:

[tex]d=\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]

...in which [tex](x_{1} ,y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] are the two given coordinates.

Answer: y= -3x

Step-by-step explanation:

Use the slope-intercept form to find the slope.

m = −3

To find an equation that is parallel to y = −3x + 2, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.

(0,0)

m = −3

Using the point-slope form

y − y1 = m (x − x1), plug in

m = −3, x1 = 0, and y1 = 0.

y − (0) = (−3) (x−(0))

Solve for y

y = −3x

Answer:

y=3x+3

Step-by-step explanation:

(2,9)

x=2

y=9

-Slot these numbers into the equation y=mx+c

-Solve for c

y=3x+c

9=3(2)+c (We have substituted y for 9 and x for 2)

-Solve

9=6+c

(rearrange)

c+6=9

c=9-6

c=3

We have found our y-intercept (c)

Add this value into the original equation (replace the other y-intercept with your new value)

y=3x+3

Answer:

The expected number of red balls in the sample is 1.2857.

Step-by-step explanation:

The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The expected value of the hypergeometric distribution is:

[tex]E(X) = \frac{nk}{N}[/tex]

3 red balls in the sample:

This means that [tex]k = 3[/tex]

3 balls are drawn:

This means that [tex]n = 3[/tex]

Total of 3 + 4 = 7 balls:

This means that [tex]N = 7[/tex]

What is the expected number of red balls in the sample?

[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]

The expected number of red balls in the sample is 1.2857.

Answer:

Angle 5 would be 119 degrees.

Step-by-step explanation:

This is because the angle that is 61 degrees and angle 5 are both supplementary angles. Supplementary angles would add up to 180 degrees and would lie on the same side of the line. So 180 minus 61 is 119.

Answer:

1.106 inches squared 2. 60 inches cubed

Step-by-step explanation:

The surface area is just calculated like this 7.5*2*2 (because there are 2 faces) = 30 then 2*4*2= 16 then 4*7.5*2= 60 then you add them to get 106

For the second all you do is multiply the three values which gets you 60

would be amazing if you picked this as brainliest :)

Answer:

Step-by-step explanation:

.Find the surface area

(7,5*4) *2 + (7,5*2) *2 + (4*2) * 2 =

60+ 30+ 16 => 106 inch²

2.Find the volume

7,5 * 2*4 =>60 inch³
