Answer:

1/5 of a box of candy

Step-by-step explanation:

Because John has 4 boxes of candy, he needs to divide this by his 20 classmates. So we have 4/20, which reduces to 1/5. So each classmate would get 1/5 of a box of candy (assuming that Josh himself does not get any candy).

Step-by-step explanation:

Answer:

the numbers would be 5 and 7.

Step-by-step explanation:

"the difference of two numbers is 2."

"their sum is 12."

since the difference of 7 and 5 is 2 and the sum of 7 and 5 is 12, 5 and 7 are the numbers that fulfill the statement.

Answer:

Because [tex]x = y[/tex], then the solution is unique.

Step-by-step explanation:

Given

[tex]Ax = b[/tex]

[tex]Ax=0[/tex]

See comment for complete question

Let there be two solutions x and y.

Such that:

[tex]Ax = b[/tex] and [tex]Ay = b[/tex]

Since:

[tex]Ax = Ay = b[/tex]

Then:

[tex]Ax - Ay = b - b[/tex]

[tex]Ax - Ay = 0[/tex]

This implies that:

[tex]Ax - Ay = A(x-y) = 0[/tex]

The only trivial solution is:

[tex]Ax - Ay = A(x-y) = 0[/tex]

Such that:

[tex]x -y = 0[/tex]

Then

[tex]x = y[/tex]

Because [tex]x = y[/tex], then the solution is unique.

Answer:

jesse or sam i think its sam by a little bit.

Step-by-step explanation:

Answer:

Sam

Step-by-step explanation:

Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:

Sam

4.2/6

= 0.7 km/min

Amanda

3.2/8

= 0.4 km/min

Jesse

3/5

= 0.6 km/min

Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.

Step-by-step explanation:

Answer:

Math sections = 20

English sections = 16

Philosophy sections = 8

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of Math sections.

y is the number of English sections.

z is the number of Philosophy sections.

Available classrooms limit the total sections of all three courses to 44.

This means that [tex]x + y + z = 44[/tex]

4 less English sections than Math sections.

This means that [tex]y = x - 4[/tex]

In any quarter student demand for the optional Philosophy course is half as many sections as English sections.

This means that [tex]z = \frac{y}{2} = \frac{x - 4}{2}[/tex]

Finding the number of Math sections:

We have both y and z as functions of x. So

[tex]x + y + z = 44[/tex]

[tex]x + x - 4 + \frac{x-4}{2} = 44[/tex]

[tex]2x + \frac{x-4}{2} = 48[/tex]

Multiplying everything by 2

[tex]4x + x - 4 = 96[/tex]

[tex]5x = 100[/tex]

[tex]x = \frac{100}{5}[/tex]

[tex]x = 20[/tex]

Then

[tex]y = x - 4 = 20 - 4 = 16[/tex]

[tex]z = \frac{y}{2} = \frac{16}{2} = 8[/tex]. So

Math sections = 20

English sections = 16

Philosophy sections = 8

Step-by-step explanation:

Sorry it dark my time is 7:37pm Wed Feb 24 2021!!!!

Answer:

The population of California is [tex]3.3216 * 10^{7}[/tex] more than the population of Wyoming.

Alternatively, the population of California is [tex]6.64 * 10^{1}[/tex] times the population of Wyoming.

Step-by-step explanation:

The first part is to take the numbers out of the scientific notation. The estimated population of California is 38,800,000, and the population of Wyoming is 584,000.

Not that we've done that, let's start with the first part of the problem.

"The population of California is __________ more than the population of Wyoming."

This is a statement of subtraction, because it's not asking how many TIMES more. So, we subtract Wyoming's population from California's population.

[tex]38,800,000 - 584,000 = 38,216,000.[/tex]

Putting that number into scientific notation is easy: move the decimal to the place in the number where there will only be one number in front of the decimal: 3.3216. How many number slots until you have only one number in front of the decimal? 7. So, we know that the power of 10 is going to be 7. So, the first part of the question answers to:

[tex]3.8216 * 10^{7} .[/tex]

Now for the second part.

"Alternatively, the population of California is _________ times the population of Wyoming."

This is a problem of division. The question is asking us to divide California's population by Wyoming's population.

[tex]\frac{38,800,000}{584,000} = 0.664383562 * 10^{2} .[/tex]

We need to have one number in front of the decimal point, so we move it behind the first 6, giving us 6.64. Because we did this, we need to bump the exponent from 2 to 1, leaving us with:

[tex]6.64 * 10^{1}.[/tex]

So, the answer to the question is:

1. [tex]3.8216 * 10^{7}.[/tex]

2. [tex]6.64 * 10^{1}.[/tex]

Hope this helped you, and I hope you get a perfect score!! :)

Answer:

The population of California is ( 3.8216 x 10⁶ ) more than the population of Wyoming.

Alternatively, the population of California is ( 6.64 x 10¹ ) times the population of Wyoming.

  (c, p, b) = (3, 5, 4)

Step-by-step explanation:

A matrix solver is useful for this purpose. Most graphing calculators will do this, as will a number of web sites. Attached is the output from math software that also solves the matrix equation easily.

The solution is (c, p, b) = (3, 5, 4).

Answer:

Diana's score is better.

Step-by-step explanation:

In Diana case :

Score = 92

Mean score , μ = 71

Standard deviation σ = 15

So,

P( x ≥ 92 ) = 1 - P( x ≤ 92 )

                = 1 - P(z ≤ [tex]\frac{x - u}{\sigma}[/tex] )

                = 1 - P( z ≤ [tex]\frac{92 - 71 }{15}[/tex] )

                = 1 - P( z ≤ 1.4 )

                = 1 - 0.9192

                = 0.0808 = 8.08 %

⇒P( x ≥ 92 ) = 8.08%

∴ we get

Diana score is > 91.92% other students in the class.

In Micheal case :

Score = 688

Mean score , μ = 493

Standard deviation σ = 150

So,

P( x ≥ 688 ) = 1 - P( x ≤ 688 )

                = 1 - P(z ≤ [tex]\frac{x - u}{\sigma}[/tex] )

                = 1 - P( z ≤ [tex]\frac{688 - 493 }{150}[/tex] )

                = 1 - P( z ≤ 1.3 )

                = 1 - 0.9032

                = 0.0968 = 9.68 %

⇒P( x ≥ 688 ) = 9.68%

∴ we get

Micheal score is > 90.32% other students in the class.

From both scores , we can conclude that

Diana's score is better.
