What is the volume of a hemisphere with a radius of 3.1 in, rounded to the nearest tenth of a cubic inch?

Pls help me

Answers

Answer 1

Answer:

Formula: V = (2/3) π r 3.

Radius is 3cm.

So, now we can plug it in to solve for the volume.

V = (2/3) π 3^3

First, let's multiply 3^3.

3^3 = 27

Then, 27 x π = 84.82

After, multiply by 2/3.

84.82 x 2/3 = 56.55

Lastly, round 56.55 to the nearest tenth of a cubic centimeter.

56.55 = 56.6

Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

Step-by-step explanation:

hoped this helped

Answer 2
The answe is 56.6 cm ^3

Answers

Answer:

(15,9)

Step-by-step explanation:

let [tex]x_{1}=5, x_{2}=25, y_{1}=10, y_{2}=8\\[/tex]

where the formula of the midpoint is ([tex]\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2}[/tex])

so, ((5+25)/2, (10+8)/2)

Thus, (15,9)

geometry homework!!
A cylinder is shown below.

Answers

It should be the first one since I got 245.0442 which is the closest to it

Answer: 244. 92 cm

Step-by-step explanation:

The surface area formula for a cylinder is written as SA = 2πrh + 2πr^2

The dimensions of the cylinder has a length of 6 cm diameter and a height of 10 cm. Radius is basically half of the diameter, so 3 cm. We use these numbers to substitute into the formula.

SA = 2π(3)(10) + 2π3^2

SA = 2π(30) + 2π(9)

SA = 60π + 18π

SA = 78π

SA = 245.044 cm

244.92 is close enough to 245.004, so 244.92 is the answer.

Which value of m makes the equation true?
8+m=27
Hurry I need an answer!!!!

Answers

Answer:

19

Step-by-step explanation:

given that 8 + m = 27

we need to find m

we can do this by isolating the variable using inverse operations

8 + m = 27

we want to get rid of the 8 in 8 + m

The opposite of addition is subtraction

So we want to subtract by 8 but remember what ever we do to one side we want to do to the other side

So we subtract 8 from each side

8 - 8 cancels out

27 - 8 = 19

we're left with m = 19

Which equation has the least steep graph?
O A. y=-x-9
O B. y=-7x-2
O c. y = 2x + 1
O D. y= x+6
SUBMIT

Answers

Your version of D is different from the picture y = 1/4 x + 6

However steepness is not related to the sign of the coefficient of x!
In your four options A and D both have a steepness of 1:1 (45 degrees of slope). One slopes up and the other down.

In the original question D has a slope of 1:4 which is much smaller than B which is 7:1

y= -1/4x+6 equation has the least steep of the slope of the graph. So, the correct option is D.

What is Graph?

A graph is a framework made up of a number of things, some of which are paired together to form "related" objects. The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Bar, line, histogram, and pie charts are the four fundamental types of graphs used in statistics. Equation of a line in standard form: y=mx+c, where m is the slope and c is the y-intercept

We can identify the equation with least steep graph since we are aware of the slope for all equations.

We determine the slope's lowest value, m, to determine which graph is the least steep.

Because of this, y= -1/4x+6

Therefore, the correct option is D.

During a flu epidemic, 35% of the school's students have the flu. Of those with the flu, 90% have high
temperatures. However, high temperatures are possible for people who do not have the flu. It is estimated that
12% of those without the flu have high temperatures.
If a student has a high temperature, what is the probability that the student has the flu?

Answers

Answer: 0.8015

Step-by-step explanation:

Let F= event that a person has flu

H= event that person has a high temperature.

As per given,

P(F) =0.35

Then P(F')= 1- 0.35= 0.65               [Total probability= 1]

P(H | F) = 0.90

P(H|F') = 0.12

By Bayes theorem, we have

[tex]P(F|H)=\dfrac{P(F)\timesP(H|F)}{P(F)\timesP(H|F)+P(F')\timesP(H|F')}\\\\=\dfrac{0.35\times0.90}{0.35\times0.90+0.65\times0.12}\\\\=\dfrac{0.315}{0.315+0.078}\approx0.8015[/tex]

Required probability = 0.8015

Angela bought two pairs of shoes for a total of $138$ The difference in the price of shoes was $42. How much was the more expensive pair of shoes? Use systems of equations to solve. You must use substitution to solve

Answers

Answer:

$90

Step-by-step explanation:

Variable x = Less Expensive Shoe

Variable y = More Expensive Shoe

Set up equations:

x + y = 138

x + 42 = y

The problem says to use substitution to solve, meaning we must substitute one variable for a different value. I will substitute variable y in the first equation for x + 42 as this equals y in the second equation.

x + x + 42 = 138

Combine like terms

2x + 42 = 138

Subtract both sides by 42 to isolate variable x

2x = 96

Divide both sides by 2 to isolate variable x

x = 48

Substitute variable x for 48 and solve for y. I will use the second equation for this.

48 + 42 = y

Combine like terms

90 = y

I defined y as the more expensive pair of shoes. Since the problem only asks for the price of the more expensive shoes, the answer is $90.

A sample of size n equals 76 is drawn, and the sample mean is 47. The population standard deviation is 25. Compute the value of the test statistic and determine if the H subscript 0 is rejected at the alpha equals 0.05 level.

Answers

Answer:

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 43

Given that the mean of the sample = 47

Given that the standard deviation of the Population = 25

Given that the sample size 'n' = 76

Step(ii):-

Null hypothesis:H₀: μ = 43

Alternative Hypothesis: H₁: μ ≠ 43

Test statistic

           [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

          [tex]Z = \frac{47-43 }{\frac{25}{\sqrt{76} } }[/tex]

          Z = 1.39

Level of significance = 0.05

The critical value = 1.96

Final answer:-

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted
