Answer:

[tex]288\pi[/tex] [tex]units^3[/tex]

Step-by-step explanation:

The formula for the volume of a sphere is: [tex]\frac{4}{3} \pi r^3[/tex]

where r is the radius.

So when you plug in 6 for r and you get:

[tex]\frac{4}{3} \pi 6^3 = 288\pi[/tex]

Answer:

Lower limit: 49.44 minutes

Upper limit: 53.16 minutes

Step-by-step explanation:

T interval

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 40 - 1 = 39

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 39 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.023

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.023\frac{5.8}{\sqrt{40}} = 1.86[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 51.3 - 1.86 = 49.44 minutes

The upper end of the interval is the sample mean added to M. So it is 51.3 + 1.86 = 53.16 minutes

Lower limit: 49.44 minutes

Upper limit: 53.16 minutes

finding the volume of cube is equal to 2 × 3 × 4

so

v of cubes is 24

now

twice of it is 2 ×24

Answer:

Step-by-step explanation:

If the bag has 100 marbles and 7+2+11=20 then you subtract what you got adding the quantities you already know from the total, and you have your answer :D

The measure of m∠1 and m∠2 are 60. 75° and 119. 25° respectively.

Note that corresponding angle are equal

m∠ 1 = 60. 75°; this is so because corresponding angles are equal

m∠1 and m∠2 are on a straight line

Also note that angles on a straight line sum up to 180°

m∠1 + m∠2 = 180°

60. 75° + m∠2 = 180°

Make m∠2 subject of formula, we have

m∠2 = 180° - 60. 75°

m∠2 = 119. 25°

Thus, the measure of m∠1 and m∠2 are 60. 75° and 119. 25° respectively.

Answer:

1x - 1

Step-by-step explanation:

Find the slope.

y2 - y1/ x2 - x1               3-2/ 2 - 1 = 1

So far this is our equation: y = 1x + b; to find the y - intercept, plug in the original values. Simplify the equation

2 = 1(3) + b

2 = 3 + b

Answer:

Step-by-step explanation:

For the product to be zero one of the picks needs to be zero. It is easier to find the probability of NOT selecting a zero and subtract that from one.

P(0)=1-P(!0)

P(0)=1-(5/6)(4/5)

P(0)=1-4/6

P(0)=(6-4)/6

P(0)=1/3

Step-by-step explanation:

Given

[tex]H = \{(-5,0),(4,3),(-8,3)\}[/tex]

Required

The domain and the range

A function represented as:

[tex]Function = \{(x_1,y_1),(x_2,y_2)......(x_n,y_n)\}[/tex]

Where:

[tex]Domain=x_1,x_2,....,x_n[/tex]
