Mashutka [201]

Answer:

Option B. $11\%$

Step-by-step explanation:

we know that

The probability that the dart will land in the section labeled with a X is equal to divide the area of the smaller green circle by the total area

$P=\frac{\pi (2)^{2}}{\pi (6)^{2}}\\ \\P=\frac{4}{36}\\ \\P=\frac{1}{9}\\ \\P=11\%$

The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 4004

nydimaria [60]

Answer:

0.8151 is the probability that the weight will be less than 4293 grams.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 4004 grams

Variance = 103,684

$\sigma = \sqrt{103684} = 322$

We are given that the distribution of weight of newborn baby is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(weight will be less than 4293 grams)

P(x < 4293)

$P( x < 4293) \\\\= P( z < \displaystyle\frac{4293 - 4004}{322}) \\\\= P(z < 0.8975)$

Calculation the value from standard normal z table, we have,

$P(x < 4293) =0.8151 = 81.51\%$

0.8151 is the probability that the weight will be less than 4293 grams.

What is the image of the point (0,5)(0,5) after a rotation of 180^{\circ}180

almond37 [142]

The image of the point (0,5) after a rotation of 180° counterclockwise about the origin is (0, -5).

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is:

What is the image of the point (0,5) after a rotation of 180° counterclockwise about the origin?

The rule for the above transformation:

(x, y) → (-x, -y)

(0, 5) → (0, -5)

Thus, the image of the point (0,5) after a rotation of 180° counterclockwise about the origin is (0, -5).
