What’s the answer to this?

Answer:

1/2

Step-by-step explanation:

there is two side of a coin, so there is a 1/2 chance that you will head heads.

A coin has two sides, one side is heads, and the other is tails. Since there are 2 sides the probability of getting either heads or tails is 1/2. Therefore, the probability of flipping a coin and getting heads is C) 1/2.

Answer:The answer is A

Step-by-step explanation:

The solution is x = -2/5.

The equation can be simplified by doing some algebra.

- 2/(x - 1) = 4

-2 = 4 (x-1)

-2 = 4x - 4

2 = 4x

x = 4/2

x= 0.5

An equation is a mathematical announcement that is made up of expressions connected by way of an identical sign. for instance, 3x – 5 = 16 is an equation. solving this equation, we get the fee of the variable x as x = 7.

Answer:

0.35

Step-by-step explanation:

Just divide 8.05 by 23

The answer you are looking for is 0.35.

To solve for any variable (N in this case) you must get it by itself, by doing the opposite operation. To do so for this problem, divide 23 from both sides. In doing so, N will be by itself, and you'd then just divide 23 from 8.05. Thus getting 0.35 as an answer.

Answer:

Radius is 2 centimeters

Step-by-step explanation:

4π is the area of a circle

Area of a circle = πr^2

4π / π = πr^2 / π

sqrt(4) = sqrt(r^2)

2 = r

Answer:  Radius is 2 centimeters

Answer:

Width = 5 cm

Length = 7 cm

Step-by-step explanation:

Width = w

Length = 2w - 3

Perimeter = 24 cm

2* (length + width ) = 24

2*(2w-3 +w) = 24

2*(3w -3) = 24

3w - 3 = 24/2

3w - 3 = 12

3w = 12+ 3

3w = 15

w = 15/3

w = 5cm

Length = 2w - 3 = 2*5 - 3 = 10-3 = 7 cm

length = 7 cm

The given function is even.

Solution:

If f(-x) = f(x), then the function is even.

If f(-x) = -f(x), then the function is odd.

Given function:

[tex]f(x)=x^{6}-x^{4}[/tex]

Substitute x = -x

[tex]f(-x)=(-x)^{6}-(-x)^{4}[/tex]

          [tex]=x^{6}-x^{4}[/tex]

          = f(x)   (given)

   f(-x) = f(x)

From the definition, it is even.

Hence the given function is even.

The theoretical probability of drawing an 'A' from the word 'ALABAMA' is 0.57. This result arrives from dividing the number of 'A's (4) by the total number of letters in 'ALABAMA' (7).

The question deals with a probability problem related to the selection of letters from the word 'ALABAMA'. The word 'ALABAMA' has 7 letters out of which 4 are 'A's. The theoretical probability is calculated as the number of successful outcomes divided by the total number of outcomes. Since we are interested in drawing an 'A', the successful outcomes are the number of 'A's which is 4, and the total outcomes are the total number of letters which is 7.

To calculate theoretical probability, you divide the number of successful outcomes by the total number of outcomes. In this case, the calculation will be 4 / 7 = 0.57 (rounded to the nearest hundredth).

So, the theoretical probability of drawing an A from the word 'ALABAMA' in decimal form, rounded to the nearest hundredth, is 0.57.

Answer

x= 2.2

Credit to - https://brainly.com/question/4504639

Answer:

Option C, Carina should have subtracted 3.40 from 5.27.

Step-by-step explanation:

Step 1:  Convert words into an equation

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound.

3.40 + 0.85p = 5.27

Step 2:  Solve for p

3.40 + 0.85p - 3.40 = 5.27 - 3.40

0.85p / 0.85 = 1.87 / 0.85

p = 2.2

The error was found when she add 3.40 to 5.27 instead of subtracting.

Answer:  Option C, Carina should have subtracted 3.40 from 5.27.

The solution to the system of equations is x = 4 and Y = 4.

To solve the system of linear equations, we can use substitution. Since we have the equation Y = 3/2x - 2, we can substitute this expression for Y in the first equation.

Substituting Y = 3/2x - 2 in 4x - 2y = 8:

4x - 2(3/2x - 2) = 8

Simplifying the expression:

4x - 3x + 4 = 8

x + 4 = 8

Solving for x:

x = 8 - 4

x = 4

Substituting the value of x into Y = 3/2x - 2:

Y = 3/2(4) - 2

Y = 6 - 2

Y = 4

Therefore, the solution to the system of equations is x = 4 and Y = 4.

We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.

[tex] \therefore \: 39 + 21 = 60 > 16 \\ \\ \: \: \: \: \: \: 16 + 39 = 55 > 21 \\ \\ \: \: \: \: \: \: 16 + 21 = 37 \ngtr39 \\ \\ \because \: last \: mathematical\: statement \: is \:\\ defying \: the \: above \: law \\ [/tex]

Therefore, it is not possible to form a triangle with given measurements.

The given lengths cannot form the sides of a triangle because they dont satisfy the sides of a triangle rule.

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

Given here, are the sides 16 m, 21 m , 39m

now if the two sides are 16, 21 then their sum is 16+21 = 37 but 37<39 thus combination of lengths cannot form a triangle

Hence, the lengths 16,21,39 cannot form the sides of a triangle

⇒ £500 = 500 × 11.15 = £5575

£1 = 1.25 CHF

Final answer:

The value of (f•g)(2), given f(7)=12 and g(2)=7, is 12. This is found by first applying g to 2 to get 7, and then applying f to get f(7), which equals 12.

Explanation:

The question pertains to the composition of functions and the use of the chain rule in calculus. Given that f(7)=12 and g(2)=7, we need to find the value of (f•g)(2). The notation (f•g)(x) means we first apply g to x, and then apply f to the result of g(x). Therefore, to find (f•g)(2), we first find g(2), which is 7, and then find f(g(2)) which is f(7). Since we know that f(7)=12, the value of (f•g)(2) is therefore 12.

the volume of cube with edge length 11 m is [tex]Volume = 1331m^3[/tex] .

Step-by-step explanation:

Here  we have a side length of a cube as 11 m . We need to find the volume of cube . Let's find out:

We know that every side of a cube is identical and equal . And volume of cube is given by formula :

⇒ [tex]Volume = (side)^3[/tex]   ...........(1)

According to question we have following parameters as

[tex]side = 11m[/tex]

Putting this in (1)

⇒ [tex]Volume = (11m)^3[/tex]

⇒ [tex]Volume = 11(11)(11)m^3[/tex]

⇒ [tex]Volume = (121)(11)m^3[/tex]

⇒ [tex]Volume = 1331m^3[/tex]

Therefore , the volume of cube with edge length 11 m is [tex]Volume = 1331m^3[/tex] .

The volume of the cube is 1331 m³

Explanation:

Given:

side of the cube, a = 11m

Volume of the cube, v = ?

we know:

Volume of the cube = (a)³

V = (11m)³

V = 1331 m³

Therefore, the volume of the cube is 1331 m³

The unit rate at which the group of rangers plants trees is 5/8 of an acre per week, which is found by calculating the daily acreage planted and then multiplying by the number of workdays in a week.

To determine the unit rate per week of the group of rangers planting trees, we need to calculate how much of an acre they can plant in a standard work week. As it takes them 4 days to plant trees on 1/2 acre, they will plant 1/2 acre in every 4 days of work. Since they work 5 days per week, we can adjust the ratio to calculate the weekly rate:

Therefore, the unit rate at which the group of rangers plants trees is 5/8 of an acre per week.
