Option 4: 2.1 + 2x = 7.5
Damm [24]3 years ago

Answer:

The value of x is 2.7  and the equation used for finding the value of x is 7.5 = 2.1 + 2x.

Step-by-step explanation:

As given

The isosceles triangle has a perimeter of 7.5 m  .

if the shortest side, y measures 2.1 m

In the isosceles triangle two sides of the triangle are equal .

Let us assume that the two equal sides each of length x .

Thus

Perimeter = Sum of all sides

Perimeter = x + x + y

7.5 = 2x + 2.1

7.5 - 2.1 = 2x

5.4 = 2x

x = \frac{5.4}{2}

x = 2.7 m

Therefore the value of x is 2.7  and the equation used for finding the value of x is 7.5 = 2.1 +2x.

liraira [26]

Answer:

<em>A.) There is a 3.4% chance that a random sample of 50 expectant mothers will have a mean age of 26.5 years old or greater if the mean age for a first time mother is 26 years old.</em>

Step-by-step explanation:

The mean age for a first time mother is assumed 26 years old (null hypothesis) and <em>p-value</em> of the sample mean (26.5 years ) is found as 0.034.

This is the probability of having first time mother mean age 26.5 or greater <em>under the assumption of null hypothesis. </em>

13 + 11s = -15 + 8s − 20
koban [17]

<em>Answer,</em>

<em><u>S = -16</u></em>

<em>Explanation,</em>

<em><u>Step 1: Simplify both sides of the equation.</u></em>

<em>13 + 11s = − 15 + 8s − 20</em>

<em>13 + 11s = − 15 + 8s + − 20</em>

<em>11s + 13 = (8s) + (</em><em><u>− 15</u></em><em> + </em><em><u>− 20</u></em><em>) </em><em>(Combine Like Terms)</em>

<em>11s + 13 = 8s + − 35</em>

<em>11s + 13 = 8s − 35</em>

<em><u>Step 2: Subtract 8s from both sides.</u></em>

<em>11s + 13 − 8s = 8s − 35 − 8s</em>

<em>3s + 13 = − 35</em>

<em>Step 3: Subtract 13 from both sides.</em>

<em>3s + 13 − 13 = − 35 − 13</em>

<em>3s = − 48</em>

<em><u>Step 4: Divide both sides by 3.</u></em>

<em>3s/3 = −48/3</em>

<em>s = -16</em>


<u><em>Hope this helps :-)</em></u>
