Answer:

9 inches

Step-by-step explanation:

The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below

The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size

population standard deviation = 36

sample size = 144

standard deviation of the sample mean = 36/ sqrt(144)

=36/12

The margin of error is the number of standard deviations above the mean * the standard deviations

margin of error = 3 * 3

= 9 inches

raw and label a model to find the value of 3··81 4·· 8. Then write and solve an equation that matches the model.

For is mathematically given as

<h3>What is the solution of an equation that matches the model.?</h3>

Considering line segments from (0,0,0)origin to (3,0,0) , (3,5,1) and (0,5,1) under the infulence of force

Generally, the equation for force is mathematically given as

F = z2i + 5xyj + 2y2k

Therefore, Considering u*v

$u * v = (u_1j+u_2j+u_3k) * (v_1i+v_2j+v_3k)$

$u* v = u_1v_1(i * i) + u_1v_2(i * j)+u_1v_3(i * k) + u_2v_1(j * i) + u_2v_2(j * j)+u_2_3(j* k) + u_3v_1(k * i) + u_3v_2(k * j)+u_3v_3(k * k)$

Where

$i * i = j *j=k * k=0$

Hence

$u* v = u_1v_2k-u_1v_3j-u_2v_1k+u_2v_3i +u_3v_1j - u_3v_2i$

$u = (u_1,u_2,u_3) = (0,5,1)\\\\v = (v_1,v_2,v_3) = (-3,0,0)$

The normal equation formed

-3y + 15z = 0

z= (1/5)y

Considering the level surface and differential surface area

h(x,y,z) = -y + 5z =0

$dS = |grad(h)| dA$

In terms of the x and y coordinates of (3,0,0) and (3,5,1) and (0,5,1), we can state that the ranges are 0 to 3 and 5 respectively.

Answer:

The points on a line can be assigned real number coordinates (think of numbers on a number line). The distance between any two points is their difference.

A proportional relationship is formed when y=1 and x=-4 what is the value of x when y=4

ICE Princess25 [194]

Answer:

x = - 16

Step-by-step explanation:

The equation relating two proportional quantities is

y = kx ← k is the constant of proportionality

To find k use the condition when y = 1, x = - 4

k = $\frac{y}{x}$ = - $\frac{1}{4}$

y = - $\frac{1}{4}$ x ← equation of proportionality

when y = 4, then

4 = - $\frac{1}{4}$ x (multiply both sides by - 4 )

x = - 16

Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container

Alecsey [184]

Answer:

2 5/12 cups

Step-by-step explanation:

Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container

The amount of juice remaining in the measuring cup is calculated as:

3 2/3 - 1 1/4

= 3 - 1 + ( 2/3 - 1/4)

LCD = Lowest Common Denominator is 12

= 2 + (4 × 2 - 3 × 1/12)

= 2 + (8 - 3/12)

= 2 + 5/12

= 2 5/12 cups

Hence, the amount of juice remaining in the measuring cup = 2 5/12 cups of juice

Last one include explanation thank you !!!

Lyrx [107]

Answer:

Angle 2 = 105

Step-by-step explanation:

Since these angles are cut by a transversal the angle from above is congruent to angle #2. You can say the theorem that is used to make these two congruent is the Alternate exterior angles theorem which states this.

Hope this helped!
