Mathematics

That's true.  The definition of an isosceles triangle is that it has at least 2 sides equal in length.  Therefore, isosceles can be equilateral, but equilateral cannot be isosceles.

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?<br><br> –10<br> –5<br> –3<br> –1
givi [52]

Answer: -1

Step-by-step explanation:

Given by your question

2(3x-1)≥4x-6

Distributive property to take off the parentheses

2×3x-2×1≥4x-6

6x-2≥4x-6

Subtract 4x on both sides (Subtractive property of equality)

6x-2-4x≥4x-6-4x

2x-2≥-6

Add 2 on both sides (Addition property of equality)

2x-2+2≥-6+2

2x≥-4

Divide 2 on both sides (Division property of equality)

2/2 x≥-4/2

x≥-2

----------------------------------------------------------------------------

Looking at the options you've provided.

-10 INCORRECT, it is not greater or equal to -2

-5 INCORRECT, it is not greater or equal to -2

-3 INCORRECT, it is not greater or equal to -2

-1 CORRECT, it is greater than -2

Hope this helps!! :)

Delaware was the first state to enter the Union and Hawaii was the 50th. If we order the positions of entry for the rest of the
Anna71 [15]

Answer:

State A was the <u>12th</u> state to enter the Union. State B was the <u>11th</u> state to enter the Union.

Step-by-step explanation:

Let's call x to the order-of-entry of State B, therefore the order-of-entry of State A is x+1. Given that he product of their order-of-entry numbers is 132:

x*(x+1) = 132

x² + x - 132 = 0

Using quadratic formula:

x = \frac{-b \pm \sqrt{b^2 -4(a)(c)}}{2(a)}

x = \frac{-1 \pm \sqrt{1^2 -4(1)(-132)}}{2(1)}

x = \frac{-1 \pm 23}{2}

x_1 = \frac{-1 + 23}{2}

x_1 = 11

x_2 = \frac{-1 - 23}{2}

x_2 = -12

The negative solution has no sense in the context of our problem, then the solution is x = 11.

g The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 cus
vagabundo [1.1K]

Answer:

The right solution is "0.196".

Step-by-step explanation:

The given values are:

Standard deviation,

\sigma=1 \ minute

Sample size,

n=100

Confidence level,

c=95%

  =0.95

Now,

For \alpha=1-c

         = 1-0.95

         =0.05

then,

Z_{\frac{\alpha}{2} } = Z_{\frac{0.05}{2} }

     =Z_{0.025}

     =1.96

The margin or error will be:

⇒ E=Z_{\frac{\alpha}{2} } (\frac{\sigma}{\sqrt{n} })

On substituting the values, we get

       = 1.96(\frac{1}{\sqrt{100} })

       = 1.96\times \frac{1}{10}

       = 0.196
