Answer:

Read Explanation

Step-by-step explanation:

A standard devation of 15 means 68% of the norm group has scored between 85 (100 – 15) and 115 (100 + 15). In other words, 68% of the norm group has a score within one standard deviation of the average (100). Also, 95% of the norm group has an IQ score within two standard deviations of the average.

Emily has $3.15 worth of dimes and quarters. She has twice as many dimes as quarters. Determine the number of dimes and the numb
Cerrena [4.2K]

Answer:

The number of dimes is <u>14</u> and the number of quarters is <u>7</u>.

Step-by-step explanation:

Given:

Emily has $3.15 worth of dimes and quarters.

<em><u>She has twice as many dimes as quarters.</u></em>

Now, to determine the number of dimes and the number of quarters.

Let the number of quarters be x.

And the number of dimes be  2x.

So, the total worth of dimes and quarters = $3.15.

Now, to get the number of dimes and quarters:

According to question:

0.10(2x)+0.25x=3.15

0.20x+0.25x=3.15

0.45x=3.15

<em>Dividing both sides by 0.45 we get:</em>

x=7.

<em>Thus, the number of quarters</em> = 7.

<em>So, the number of dimes</em> = 2x=2\times 7=14.

Therefore, the number of dimes is 14 and the number of quarters is 7.

What is the slope of the line?
12345 [234]

You can find the slope using the following formula:

\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ where\colon \\ (x1,y1)=(0,2) \\ (x2,y2)=(1,0) \\ m=\frac{0-2}{1-0}=\frac{-2}{1}=-2 \end{gathered}

Find the value of the length <br> x<br> rounded to 1 DP.
bagirrra123 [75]

Length of x is 98.2 m

<u>Step-by-step explanation:</u>

Step 1:

Use the trigonometric ratio tan 27° to find the common side of both the right angled triangles.

tan 27° = opposite side/adjacent side = opposite side/9

∴ Opposite side = 9 tan 27° = 9 × - 3.27 = -29.46 m

Step 2:

Use this side and trigonometric ratio cosine to find the value of x.

cos 49° = adjacent side/x = -29.46/x

∴ x = -29.46/cos 49° = -29.46/0.30

     = 98.2 m (negative value neglected)
