Answer:

About 159 weigh more than 165 g and about 159 g weigh less Than 135 g

Step-by-step explanation:

Given that :

Mean, μ = 150

Standard deviation, σ = 15

Using the Zscore formula :

Zscore = (x - μ) / σ

For x > 165

P(x > 165)

Z = (165 - 150) / 15

Z = 15 /15 = 1

P(Z > 1) = 0.15866 (Z probability calculator)

1000 * 0.15866 = 158.66 = 159

For x < 135

P(x < 135)

Z = (135 - 150) / 15

Z = - 15 /15 = - 1

P(Z > - 1) = 0.15866 (Z probability calculator)

1000 * 0.15866 = 158.66 = 159

The sign of the product of -35 and -625 is positive, negative, or zero
IRISSAK [1]

Answer:

Positive

Step-by-step explanation:

The product of two negative numbers has a positive sign, whereas the product of a positive and a negative number is negative.

Since -35 and -625 are both negative, they would have a positive sign for their product.

Hope this helps.

Find the total area of the four walls of a room 12 m long, 10 m wide and 4 m high.
Radda [10]

Answer:

<h2>416m^2</h2>

Step-by-step explanation:

<h3>Area = Length * Width</h3><h3>Volume = Length * Width * Height</h3>

<h3>As we all can see,from the question we were given the parameters for calculating volume instead of the ones for calculating "area"</h3>

<h3>But from the the parameters, we can calculate for the total surface area</h3>

<h3>Floor = 12m ×10m = 120m^2</h3>

<h3>Roof = 12m × 10m = 120m^2</h3>

<h3>Front and back walls (x2) = 10m × 4m ×2 = 80m^2</h3>

<h3>Side walls (x2) = 12m × 4m × 2 = 96m^2</h3><h3>Total surface area</h3>

<h3>= 120m^2 + 120m^2 + 80m^2 + 96m^2</h3>

<h3>= 416 m^2</h3>

Find c such that (−3,−8), (−7,−6), and (c,4) lie on a line.
Nutka1998 [239]
If the 3 points are collinear, then the slopes of all line segments connecting the points are the same.

Thus, 

         -6 - (-8)         2
m = ------------- = -------- = -1/2
         -7 - (-3)         -4

Then the following must be true:

             4-(-6)          10
-1/2 = ------------ = ---------
             c - (-7)       c + 7

Cross multiplying, -(c+7) = 20, and c+7 = -20, so that c = -27
