The height of Jane will be 38 9/30 inches.

The process of combining two or more numbers is called the Addition.

Given that;

Trina is 54 3/4 inches tall. Morgan is 1 1/2 inches taller than Trina and Jane is 1 1/5 inches taller than Morgan.

Now,

Since, Trina is 54 3/4 inches tall.

And, Morgan is 1 1/2 inches taller than Trina.

Hence, The height of Morgan = 54 3/4 + 1 1/2

                                              = 219/4 + 3/2

                                              = 219/4 + 6/4

                                              = 225/4

And, Jane is 1 1/5 inches taller than Morgan.

Hence, The height of Jane = 225/4 + 1 1/5

                                          = 225/4 + 6/5

                                          = (1125 + 24)/30

                                          = 1149/30

Thus, The height of Jane = 38 9/30 inches

   The probability that the sample mean will be within ±5 of the population mean is 0.6826

If the population is normally distributed, the sample means will be normally distributed even with smaller samples. [This is known as the Central Limit Theorem, which states that when a large number of random samples are drawn from a population, the means of these samples will be normally distributed.]

Z=X-μ/σ

Given here, σ = 50 , μ =200 , σₓ = 5 , n = 100 ,                                                                      

                     z = 205-200/5    z = 195-200/5

we get z= ±1

From the z table, we get P( z= -1)  = 0.1587

From the z table we get P( z= 1)  = 0.8413

Thus the final answer is = 0.8413- 0.1587

Answer:

The area of the square is larger than the area of the rectangular field.

Answer:

Step-by-step explanation:

You could use 1 3/4's of a cup and 8 1/4's of a cup.

1 of the 3/4 cups is 3/4 so that covers the 3/4 of the cups of how much flour is needed.

8 of the 1/4 cups is 8/4 which is equal to 2 so that covers the rest of the flour needed.

And 2 + 3/4 is 2 3/4 which is the amount of flour that is needed.

OR

You could use 3 3/4's of a cup and 2 1/4's of a cup.

3/4 + 1/4=4/4

3/4+1/4=4/4

4/4 + 4/4 is the same thing as 1+1 which is 2, so that covers the 2 cups of the flour that is needed, and then you add another 3/4, now you have

2 3/4, which is the amount of flour needed.

Answer:

-11

Step-by-step explanation:

To find f(3), we simply need to plug 3 in for x in the function f(x) = -3x-2. This gives us:

f(3) = -3(3) - 2 = -9 - 2 = -11

Therefore, the value of f(3) is -11.

Answer:

y < 13x – 15

Step-by-step explanation:

13x – y < 15

–y < –13x +15

divide both sides by (–)

–(–y) < –(–13)x –(15)

y < 13x – 15

The representation table given indicates that the function is linear, as the difference between consecutive y-values (9-8, 8-7, and 7-6) is constant. Therefore, we can represent the function with a linear equation of the form y = mx + b, where m is the slope and b is the y-intercept.

To find the equation of the function, we can use the x- and y-values given in the table to solve for m and b. For example, using the x- and y-values (-3,9) and (-2,8), we can solve the equation 9 = m(-3) + b for m and b:

9 = -3m + b

8 = -2m + b

Subtracting the second equation from the first equation gives us:

1 = -m

So the slope of the function is -1. Substituting this value back into either equation gives us:

9 = -3(-1) + b

9 = 3 + b

6 = b

So the y-intercept of the function is 6. Therefore, the equation of the function is y = -1x + 6.

The other two representations can be solved in the same way to find the equations of those functions.

  -72030x⁴y +18750y⁵ +102900x³y² -52500xy⁴ +1470x²y +250y³

Step-by-step explanation:

You want to simplify (7x+5y)^3–(7x–5y)^3–30y(7x+5y)(7x–5y)^3.

We recognize that there are some repeated expressions here that may make it easier to simplify this without multiplying it all out.

Let a = 7x+5y, b = 7x -5y. Then the expression becomes ...

  a³ -b³ -30y·a·b³

  = (a³ -b³) -30yb²(ab)

  = (a -b)(a² +ab +b²) -30yb²·ab

Now ...

  a -b = (7x +5y) -(7x -5y) = 10y

  a² +b² +ab = (7x +5y)² +(7x -5y)² +(7x +5y)(7x -5y)

     = (7x)² +2(7x)(5y) +(5y)² +(7x)² -2(7x)(5y) +(5y)² +(7x)² -(5y)²

     = 3(7x)² +(5y)² = 147x² +25y²

So the first pair of terms expands to ...

  a³ -b³ = 10y(147x² +25y²) = 1470x²y +250y³

The last term becomes (with a positive sign) ...

  30yb²(ab) = 30y(7x -5y)²((7x)² -(5y)²)

     = 30y((7x)² -2(7x)(5y) +(5y)²)((7x)² -(5y)²) . . . . see comment below

     = 30y((7x)⁴ -(5y)⁴ -70xy((7x)² -(5y)²))

     = 72030x⁴y -18750y⁵ -102900x³y² +52500xy⁴

Putting it all together gives ...

  = -72030x⁴y +18750y⁵ +102900x³y² -52500xy⁴ +1470x²y +250y³

Additional comment

The difference of squares form is used several times here:

  p² -q² = (p -q)(p +q)

The expression ((7x)² -2(7x)(5y) +(5y)²)((7x)² -(5y)²) is decomposed to ...

  ((7x)² +(5y)²)·((7x)² -(5y)²) - 2(7x)(5y)((7x)² -(5y)²)

This lets us use the difference of squares form to simplify at least part of the expression. This whole thing gets multiplied by -30y.

A three-dimensional space's occupied volume is measured. It is typically quantified using a variety of imperial or US-standard units as well as SI-derived units. The concept of length and volume are related.

Here,

Given: A trough has a 12 foot length and a 3 foot top width. Three-foot-high isosceles triangles make up its ends. 12f 3 ft 31

So the first case:

using this we find the rate of Volume,

So,

=> dV/dt = length * height *dh/dt

=> dV/dt = 12 * 1.2 *dh/dt

=> 2 = 12*1.2* dh/dt

=> 2 = 14.4 * dh/dt

=>dh/dt = 2/14.4

=>dh/dt = 0.1388 ft/min

Therefore ,the water level is rising  by 0.1388 ft/min when h is 1.2 feet deep .

Second case:

Since water level is rising by 3/8 inch per min =0.03125 feet/min

=> dV/dt = length * height *dh/dt

=> dV/dt = 12 * 2.3 *0.03125

=>dV/dt = 0.8625 cubic feet per min

Therefore , the water is being pumped at rate of 0.8625 cubic feet per min.
