6 0

Answer:x=4

Step-by-step explanation: ok this is pretty long but here we go

  1. you can 2x+6−3x=−2x+10
  2. Simplify  2x+6-3x2x+6−3x  to  -x+6−x+6
  3. −x+6=−2x+10
  4. Regroup your terms to give you 6−x=−2x+10
  5. Subtract 6 from both of your sides to give you −x=−2x+10−6
  6. Simplify  -2x+10-6−2x+10−6  to  -2x+4−2x+4 to give you −x=−2x+4
  7. Add 2x2x to both of your sides to give you −x+2x=4
  8. Simplify  -x+2x−x+2x  to  xx to give you you answer of x=4
  9. - answer x=4  Hope this helps

bogdanovich [222]

Answer:

The 95% confidence  interval is (150\pm 8.8).

Step-by-step explanation:

The information provided is:

\bar x=150\\\sigma = 20\\n=20

The critical value for 95% confidence level is:

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

Compute the margin of error as follows:

MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

          =1.96\times\frac{20}{\sqrt{20}}\\\\=1.96\times 4.47214\\\\=8.7653944\\\\\approx 8.8

Then the 95% confidence  interval is:

CI=\bar x\pm MOE

     =150\pm 8.8

Thus, the 95% confidence  interval is (150\pm 8.8).

Explain how the architect created a scale drawing of the house. What scale did she use?
KonstantinChe [14]

Answer:

Scale used for drawing is 1 cm = 1.75 m

Step-by-step explanation:

An architect makes a scale drawing of a house.

Actual width of porch  = 7 meters

Width of porch on drawing = 4 cm

So, Actual width = Drawing width

So, 4 cm = 7 m

1 cm = 1.75 m

So, Scale: 1 cm = 1.75 m

So, Option B is correct

B)1 cm = 1.75 m
