Answer:

Part 1: The fractional part of the circumference is 1/4.

Part 2: 100.53 or 100.48 if you use 3.14 as pi

Step-by-step explanation:

Part 1: A circle is 360 degrees and a right angle is 90, so the fractional  part is 90/360 or 1/4.

Part 2: 0.5pi*r is the length of the arc. The radius, or r, is 16 cm, a half of 32. It is 2 * pi * 16 = 32 * pi. 32 * pi = 100.53 or 100.48 if you use 3.14 as pi.

Find the distance between points M(-1,-10) and (-12,-3). round to the nearest tenth
Kitty [74]

The formula of the distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have the points (-1, -10) and (-12, -3). Substitute:

d=\sqrt{(-12-(-1))^2+(-3-(-10))^2}=\sqrt{(-11)^2+7^2}=\sqrt{121+49}=\sqrt{170}

\sqrt{170}\approx13.04

Answer: d ≈ 13.0

in circle F, points A,B,C,D, and E are located on the circle such that measure of C=119°, and BE is perpendicular AD. determine
VLD [36.1K]

Answer:

Measure of arc AE = 58°

Step-by-step explanation:

As shown: ABCD is a quadrilateral, ∠C = 119°

So, ∠C + ∠A = 180°

∴ ∠A = 180° - ∠C = 180° - 119° = 61°

ΔAGB is a right triangle at G

So, ∠A + ∠B = 90°

∴ ∠ABG = 90 - ∠A = 90 - 61 = 29°

Arc AE opposite to the angle ∠ABG

So, measure of arc AE = 2∠ABG = 2 * 29° = 58°

Suppose a normal distribution has a mean of 48 and a standard deviation of 2. What is the probability that a data value is betwe
stepan [7]

Answer:

Choice D.  15.2%

Step-by-step explanation:

We have a normal...

mean u = 48

standard deviation s = 2

We want P(43 < X < 46)

We standardize.

Consider  P(43 < X)  = P( (43 - 48)/2 < Z) = P(-2.5 < Z)

P( X < 46) = P( Z < (46 - 48)/2 ) = P(Z < -1)

We want  P( -2.5 < Z < -1)

Look at Z-scores.

P( Z < -2.5)  = 0.0062

P(Z  < -1) = 0.1587

so  P(-2.5 < Z < -1) =  P(Z < -1) - P(Z < -2.5) = 0.1587 - 0.0062 = 0.1525 = 15.2%
