Answer:

LMNO is a parallelogram

Step-by-step explanation:

In the two Δ NML and LON

∵ NM = LO ⇒ given

∵ ML = ON ⇒ given

∵ NL is a common side

∴ ΔNML ≅ ΔLON ⇒(SSS)

∴ m∠MLN = m∠ONL ⇒ in alternate position

∴ LM // ON

∵ LM = ON

∵ LM and ON are two opposite sides in quadrilateral LMNO,

The weights of a large number of miniature poodles are approximately normally distributed with a mean of 8 kilograms and a stand
harina [27]

Answer and Step-by-step explanation:

Considering the table attached.

(a) over 9.5 kg;

μ = 8

σ = 0.9

z = 9.5 - 8/0.9 ≈ 1.67

P (Z > 1.67) = 0.5 - P(0<Z<1.67) = 0.5 - 0.4525 = 0.0475

(b) at most 8.6 kg;

z = 8.6-8/0.9 ≈ 0.67

P(Z < 0.67) = 0.5 + P(0<Z<0.67) = 0.5 + 0.2486 = 0.7486

(c) between 7.3 and 9.1 kg.

z₁ = 7.3-8/0.9 ≈ -0.78

z₂ = 9.1 - 8/0.9 ≈ 1.22

P(-0.78 < Z < 1.22) = P(0 < Z < 0.78) + P(0 < Z < 1.22) = 0.2823 + 0.3888 = 0.6711

Reva is playing a bean-bag toss game. For each bag that misses the board, the player scores -8 points. Reva misses the board 4 t
erica [24]

Answer:

The answer is -32.

Step-by-step explanation:

Since there is no detailed information given about the game or the total tosses in the question, i will assume that the game is concluded when each player has had 4 tosses.

Considering the information that Reva missed the board 4 times out of her total 4 tosses in the game and each miss results in -8 points, her total score for those 4 tosses should be -8x4 = -32.

I hope this answer helps.

Which of the following about the normal distribution is not​ true?
Lostsunrise [7]

Answer:

Normal distribution is a Continuous distribution.

Step-by-step explanation:

Normal Distribution:

The following information is true about normal distribution.

  • ​Theoretically, the​ mean, median, and mode are the same.
  • Its parameters are the​ mean, mu​, and standard​ deviation, sigma.
  • About two thirds of the observations fall within plus or minus 1 standard deviation from the mean.

But normal distribution is not a discrete distribution. It is a continuous distribution.

  • The normal distribution is a continuous probability distribution. This has several implications for probability.
  • The probability that a normal random variable X equals any particular value is 0.
