Answer:

2,786

Step-by-step explanation:

You can make this easier by taking the expanded form of 398:

300 + 90 + 8

7 x 300 = 2100

7 x 90 = 630

7 x 8 = 56

Then add all these values together:

2100 + 630 + 56 = 2,786

<em>The volume is 117.438</em>

<em>To find volume you have multiply Length x Width x Height, so in this case it would be 4.6 x 3.7 x 6.9 = 117.238</em>

<em>As proof here is my Calculator.</em>

<em>Hope this helps and have a nice day.</em>

Geometry help greatly needed, check photo for more information! &lt;3
vlabodo [156]

Answer:

\huge\boxed{\sf x = 55\°}

Step-by-step explanation:

When a quadrilateral is inscribed in a circle, the opposite angles of it add up to 180 degrees.

Here,

∠DCB + ∠DAB = 180 (Opposite angles of a quad inscribed in a circle.)

<u>Given that:</u> ∠DCB = 135° and ∠DAB = x

135 + x = 180

Subtract 135 to both sides

x = 180 - 135

x = 55°

\rule[225]{225}{2}

Hope this helped!

Determine the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal
marusya05 [52]

The two z-scores are -1.53 and 1.53

Step-by-step explanation:

To find the two z-scores that separate the middle 87.4% of the distribution from the area in the tails of the standard normal distribution

  1. Assume that z-score is between -c and c ⇒ P(-c < z < c) = the given value
  2. Find the value of P(z < -c or z > c) = 1 - the given value
  3. P(z < -c) + P(z > c) = the answer of the previous step
  4. 2*P(z < -c) = the answer of the previous step
  5. Find the value of P(z < -c)
  6. In the z-table having area to the left of z, look for the value closest to the value of P(z < -c) inside the table to find the closest value of z

∵ P(-c < z < c) = 87.4%

∵ 87.4% = 87.4 ÷ 100 = 0.874

∴ P(-c < z < c) = 0.874

∵ P(z > c) = 1 - 0.874 = 0.126

∴ P(z < -c) + P(z > c) = 0.126

∵ P(z > c) = P(z < -c)

∴ P(z < -c) + P(z < -c) = 0.126

∴ 2*P(z < -c) = 0.126

- Divide both sides by 2

∴ P(z < -c) = 0.063

Let us use the z-table to find the corresponding values of

z to 0.063

∵ The corresponding value of z to 0.063 = -1.53

∴ The two z-scores = -1.53 and 1.53

The attached figure for more understand

The two z-scores are -1.53 and 1.53
