My educational guess: Most likely Condensation, due to the fact that the in order for precipitation to happen (condensation must occur in short amount of time). Please know this is an educational guess and it may be wrong, you are risking your answer. And if you got it wrong because of me, I’m terribly sorry. God bless you and I hope this helped.

Find the measure of AEB<br><br> - already have answer just need the work

Digiron [165]

Based on the central angle theorem, the measure of angle AEB is: 140°.

<h3>What is the Central Angle Theorem?</h3>

According to the central angle theorem, the measure of an intercepted arc = measure of the central angle.

Arc AB = 140° [intercepted arc]

Angle AEB is the central angle.

Thus, based on the central angle theorem, the measure of angle AEB is: 140°.

A rectangular field has the area equal to that of a square field of side 60m.if the breadth of the rectangular field is 32m, fin

V125BC [204]

<u>Given</u> -

Area of rectangular field = Area of square field
side of square = 60m
breadth of the rectangular field = 32m

<u>To find</u> -

length of the rectangular field

<u>Solution</u> -

Area of square = side × side = (60 × 60)m² =

Area of square =3600m²

Hence,

Area of rectangular field = Area of square field = 3600m²

Area of rectangular field = l × b = 3600m²

=> l × 32m = 3600m²

=> l = $\sf{\frac{3600}{32}\:m}$

=> l = 112.5m

so, the length = 112.5m

Pls help me not fail

nignag [31]

Answer:

Step-by-step explanation:

Using the Cosine rule to find AC

AC² = BC² + AB² - (2 × BC × AB × cosB )

= 18² + 12² - ( 2 × 18 × 12 × cos75° )

= 324 + 144 - 432cos75°

= 468 - 111.8

= 356.2 ( take the square root of both sides )

AC = $\sqrt{356.2}$ ≈ 18.9

-----------------------------------------

Using the Sine rule to find ∠ A

$\frac{18}{sinA}$ = $\frac{18.9}{sin75}$ ( cross- multiply )

18.9 sinA = 18 sin75° ( divide both sides by 18.9 )

sinA = $\frac{18sin75}{18.9}$ , then

∠ A = $sin^{-1}$ ( $\frac{18sin75}{18.9}$ ) ≈ 66.9°

The size of the left upper chamber of the heart is one measure of cardiovascular health. When the upper left chamber is enlarged

Temka [501]

Answer:

a) 0.283 or 28.3%

b) 0.130 or 13%

c) 0.4 or 40%

d) 30.6 mm

Step-by-step explanation:

z-score of a single left atrial diameter value of healthy children can be calculated as:

z= $\frac{X-M}{s}$ where

X is the left atrial diameter value we are looking for its z-score

M is the mean left atrial diameter of healthy children (26.7 mm)

s is the standard deviation (4.7 mm)

Then

a) proportion of healthy children who have left atrial diameters less than 24 mm

=P(z<z*) where z* is the z-score of 24 mm

z*= $\frac{24-26.7}{4.7}$ ≈ −0.574

And P(z<−0.574)=0.283

b) proportion of healthy children who have left atrial diameters greater than 32 mm

= P(z>z*) = 1-P(z<z*) where z* is the z-score of 32 mm

z*= $\frac{32-26.7}{4.7}$ ≈ 1.128

1-P(z<1.128)=0.8703=0.130

c) proportion of healthy children have left atrial diameters between 25 and 30 mm

=P(z(25)<z<z(30)) where z(25), z(30) are the z-scores of 25 and 30 mm

z(30)= $\frac{30-26.7}{4.7}$ ≈ 0.702

z(25)= $\frac{25-26.7}{4.7}$ ≈ −0.362

P(z<0.702)=0.7587

P(z<−0.362)=0.3587

Then P(z(25)<z<z(30)) =0.7587 - 0.3587 =0.4

d) to find the value for which only about 20% have a larger left atrial diameter, we assume

P(z>z*)=0.2 or 20% where z* is the z-score of the value we are looking for.

Then P(z<z*)=0.8 and z*=0.84. That is

0.84= $\frac{X-26.7}{4.7}$ solving this equation for X we get X=30.648
