Answer:

x = 24

Step-by-step explanation:

Your mouse is hovering over a key part of the equation, but it looks like a plus symbol to me so I will go with that.

(4x-2) + (3x + 14) = 180 (Add 2 to 180, and subtract 14 from 180.

4x + 3x = 180 + 2 - 14

7x = 168

x = 24

theoretical probability is based on logic as in:

there's a spinner with five equal sections. There would be a theoretical probability of 20% for each section

Experimental probability is based on results of previous experiments such as:

Damien spun that same spinner 10 times and landed on the red section 3 of ten times

Answer

66.5%

Step-by-step explanation:

The markup percent is 66.7%

The first step is to calculate the unit cost

= Cost of the shirt/quantity of shirt

= 600/100

= 66

The percent mark up can be calculated as follows

= 100 × (new price-old price/old price)

= 100 × (10-6)/6

= 100 × 4/6

= 100 × 0.666

= 66.7

Hence the markup percent is 66.7%

Answer:

  yes

Step-by-step explanation:

A negative exponent in the numerator is the same as a positive exponent in the denominator (and vice versa). So, the first two expressions are equivalent.

An exponent is an indication of repeated multiplication. So, the 2nd and 3rd expressions are equivalent.

Any product can be decomposed to a product of its factors. So, the last two expressions are equivalent.

All of the expressions are equivalent.

x should be 180 I think

Step-by-step explanation:

Answer:

The minimum sample size  'n' = 1267.78

Step-by-step explanation:

Step:-1

Given that the sample mean is within 12 minutes

Given that the standard deviation of the Population(σ) = 218

Level of significance = 0.05

Critical value (Z₀.₀₅) = 1.96

Step(ii):-

The estimated error is defined by

                         [tex]E = \frac{Z_{0.05}S.D }{\sqrt{n} }[/tex]

                        [tex]12 = \frac{1.96 X 218}{\sqrt{n} }[/tex]

                        [tex]\sqrt{n} = \frac{1.96 X 218}{12}[/tex]

                       √n   = 35.606

squaring on both sides, we get

                        n = 1267.78

Final answer:-

The minimum sample size  'n' = 1267.78

Answer:

x = 24°

Step-by-step explanation:

Here's your solution

=> (4x - 2) + (3x + 14) = 180°

=> 7x + 12 = 180°

=> 7x = 180° - 12°

=> 7x = 168°

=> x = 168°/7

=> x = 24°

Answer:

50, 50, 80.

Step-by-step explanation:

An acute triangle is defined as a triangle with no interior angle larger than 90 degrees. Knowing this, and the fact that the interior angles of a triangle add up to 180 degrees, we can assume that 50, 50, and 80 are three angles that could make up an acute triangle.

Answer:

x = 3 and y = 7

Step-by-step explanation:

Given that,

8x+3y=45 .......(1)

2x+3y=27 ........(2)

We need to solve equations (1) and (2)

Multiply equation (2) by 4.

8x+12y=108 .....(3)

Subtract equation (1) from (3).

8x+12y-(8x+3y)=108-45

12y-3y = 63

9y = 63

y = 7

Put the value of y in equation (1).

2x+3(7)=27

2x+21 = 27

2x = 27-21

2x = 6

x = 3

So, the values of x and y are 3 and 7 respectively.
