help I don't know the answer​

Answer: 20

Step-by-step explanation:

Data: x=5 and 3x+4x-15

First step, Insert the 5 and multiply

3(5)+4(5)-15=15+20-15

Second step, add 15+20=35

Final step, subtract 35-15=20

The answer is 20

I hope this helps!

Answer:

b). Reject the null hypothesis and conclude the means are different.

Step-by-step explanation:

A hypothesis is characterized as null when the data/statistics display that there is no distinction between the particular features of the groups. As per the details provided, the decision would be to 'reject/deny the null hypothesis and deduce that the means of the processes are different.' This shows that there is no association among the variables due to the distinction in the means of the two processes and other data provided. Thus, option b is the correct answer.

Answer:

5 items: 1 dog bone, 3 water bowls, 1 collar

4 Items: 3 Water bowls, 1 Box Of Dog Food

2 items: 1 box of dog food, 1 collar

Answer:

First, you do 15+6 (because of the parentheses)

You get 21

then you have to do 1/3 times 21 and you get 7

Answer:

7

Step-by-step explanation:

Using BODMAS which stands for:

(Bracket, of, Division, Multiplication, Addition and Subtraction)

We first treat the bracket

  (15+6)=21

We then treat the division

(but it is already reduced to its lowest terms therefore no need, but if you like you can reduce it to a decimal though)

[tex]\frac{1}{3}[/tex]

Then we move onto the multiplication which is the last part

[tex]\frac{1}{3}[/tex] ×21= [tex]\frac{21}{3}[/tex] =7

Answer:

  θ = 60°

Step-by-step explanation:

The angle is more than 45° and less than 90°. The only viable choice is ...

  θ = 60°

__

We can only read the x-coordinate of the point on the terminal ray. It is 1/2, which is the cosine of 60°. The angle must be 60°.

Answer:

  8.  C) 24.2

  9.  A) 8.1

Step-by-step explanation:

8. The radius is shown as being 7.8 +4.3 = 12.1, so the diameter x is ...

  d = 2r

  x = 2(12.1) = 24.2

__

9. The unknown leg (y) of the right triangle can be found from the Pythagorean theorem.

  y² +11.7² = 12.5² . . . . . the radius is half the diameter

  y = √(156.25 -136.89) = √19.36 = 4.4

Then the segment of interest is ...

  x + y = 12.5

  x = 12.5 -4.4 = 8.1

Answer:

the length of a segment indicated.

Answer:A few examples of regular polygons are a triangle, quadrilateral, pentagon, hexagon, heptagon, and a decagon.

Answer:

The first 12 terms of the series are represented by:

[tex]f(12) = \Sigma\limits_{i = 1}^{12} [(-1)^{n}\cdot 2^{n-1}] = -1 + 2 - 4 + 8 - 16 + 32 - 64 + 128 -256 + 512 - 1024 + 2048[/tex]

Step-by-step explanation:

The summation notation for the series [tex]-1 + 2 -4 + 8 -16...[/tex] is represented by the expression [tex]f(n) = \Sigma\limits_{i = 1}^{n} [(-1)^{n} \cdot 2^{n-1}][/tex].

The first 12 terms of the series are represented by:

[tex]f(12) = \Sigma\limits_{i = 1}^{12} [(-1)^{n}\cdot 2^{n-1}] = -1 + 2 - 4 + 8 - 16 + 32 - 64 + 128 -256 + 512 - 1024 + 2048[/tex]

Answer:

  x = 20

Step-by-step explanation:

Multiply both sides of the equation by 4 to make the coefficient of x be 1. This will show you the solution.

 4(1/4)x = 4(5)

  x = 20

Answer:

A

Step-by-step explanation:

2+3=5, 5+3=8, 8+3=11. 2x3=6, 5x3=15, 8x3=24, 11x3=33

Answer:

A

Step-by-step explanation:

Proportional is where everything will match

so we have 2x3=6 5x3=15 8x3=24 11x3=33

This works because it continues the same line of multiplication (x3).

But like B,  you start with 4,4=16 which works, but now you have 5x4=21, which will not work because 5x4 will never equal 21

Answer:

Option A: (23 + 29/30) miles

Step-by-step explanation:

Here we just need to add two mixed numbers.

(8 + 4/5) miles and (15 + 1/6) miles.

To add these, we just separate between the whole part and the fraction part:

(8 + 4/5) miles + (15 + 1/6) miles

= (8 + 4/5 + 15 + 1/6) miles

= (8 + 15 + 4/5 + 1/6) miles

= (23 + 4/5 + 1/6) miles

Now we need to find a common multiple between 6 and 5.

So, only analyzing the fraction part of the sum, we can rewrite:

4/5 + 1/6

= 4/5*(6/6) + 1/6*(5/5)

(notice that we are multiplying both numbers by one, so we do not change the expression's value)

= (4*6)/(5*6) + (1*5)/(6*5)

= 24/30 + 5/30

So now both fractions have the same denominator.

Then, replacing that in the sum equation we get:

(23 + 4/5 + 1/6) miles =  (23 + 24/30 + 5/30) miles

= (23 + 29/30) miles

Then the correct option is option A.

Answer:

  112π ≈ 351.9 square units

Step-by-step explanation:

Assuming the smaller circle is wholly contained within the larger circle, the difference of their areas is ...

  ΔA = (π·11²) -(π·3²) = π·(121 -9) = 112π ≈ 351.9 . . . square units

__

The formula for the area of a circle is ...

  A = πr²

Answer:

= 110 g AgCl

Step-by-step explanation:

NaCl  +  Ag(NO3)  →   AgCl  +  NaNO3

         ↓                               ↑  

        mol           →           mol

      NaCl                         AgCl

[tex]\frac{45 g NaCl }{} \frac{1 mol NaCl}{57.44 g NaCl} \frac{1 mol AgCl}{1 mol NaCl } \frac{143.87 g AgCl}{1 mol AgCl} == 110 g AgCl[/tex]
