If the average weight for cats is 12

Mathematics
1 answer:
Mariulka [41]3 years ago
5 0

Answer:

3 standard deviations

from the mean is 6 pounds to 18 pounds.

Step-by-step explanation:

The above question is solved using empirical rule

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ

From the above question

μ = 12 pounds

σ = 2 pounds

Hence:.

3 standard deviations from the mean is calculated as

μ - 3σ

[12 - 3(2)] pounds

=( 12 - 6) pounds

= 6 pounds

μ + 3σ

[12 + 3(2)] pounds

=( 12 + 6) pounds

= 18 pounds

Hence,3 standard deviations

from the mean is 6 pounds to 18 pounds.

In circle Q with m/PQR = 74 and PQ = 8 units find area of sector PQR. Round
VladimirAG [237]

A circle is a curve sketched out by a point moving in a plane. The area of the sector PQR is 41.346 units².

<h3>What is a circle?</h3>

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given the radius of the circle is 8 units, while the angle of the sector is 74°. Therefore, the area of the sector is,

Area of the sector = π×R²×(74/360)

                              = π × 8² × 0.20556

                              = 41.346 units²

Hence, the area of the sector PQR is 41.346 units².

(-2,1) &amp; (1,-1) the equation of the line is
Aleonysh [2.5K]

Answer:

y = (-2/3)x - 1/3

Step-by-step explanation:

Find the equation of the line through the two points (-2, 1) and (1, -1).

As we increase x from -2 to 1 (an increase of 3), y decreases from 1 to -1 (a decrease of 2).

Thus, the slope of this line is m = rise / run = -2/3.

Using the slope-intercept formula y = mx + b, and substituting the givens m = -2/3, x = -2 and y = 1, we get:

1 = (-2/3)(-2) + b, or

1 = 4/3 + b, or 3/3 = 4/3 + b.

Then b must be 3/3 - 4/3, or -1/3, and the equation of the line is then

y = (-2/3)x - 1/3
