Sean's mom asks him how long his homework will take. He tells her that he needs to read for 25 minutes and also do some math pro

DochEvi [55]

Answer: The required equation is $h=25+m.$

Step-by-step explanation: Given that Sean's mom asks him how long his homework will take.

He tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. All together, his homework will take h minutes.

We are to write an equation for the number of minutes Sean's homework will take h, if his math problems take m minutes.

Since Sean needs to read for 25 minutes and do some math problem for m minutes, so total time that Sean will take will be

$25+m.$

Also, since Sean takes h minutes altogether to complete his homework, so the equation is written as

$25+m=h\\\\\Rightarrow h=25+m.$

Thus, the required equation is $h=25+m.$

In a set of 25 aluminum castings, four castings are defective (D), and the remaining twenty-one are good (G). A quality control

lianna [129]

Answer:

The sample space for selecting the group to test contains 2,300 elementary events.

Step-by-step explanation:

There are a total of N = 25 aluminum castings.

Of these 25 aluminum castings, n₁ = 4 castings are defective (D) and n₂ = 21 are good (G).

It is provided that a quality control inspector randomly selects three of the twenty-five castings without replacement to test.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=\frac{n!}{k!(n-k)!}$

Compute the number of samples that are possible as follows:

${25\choose 3}=\frac{25!}{3!\times (25-3)!}$

$=\frac{25\times 24\times 23\times 22!}{3!\times 22!}\\\\=\frac{25\times 24\times 23}{3\times 2\times 1}\\\\=2300$

The sample space for selecting the group to test contains 2,300 elementary events.

Divide using long division. Checky (x3+ 3x2 + x - 9) = (x - 1)

Montano1993 [528]

Answer:

x squared plus 2x minus 1.

Step-by-step explanation:

x3+3x2+x-9 is in the division "house" and x-1 is on the outside. xsquare times x equals x cubed. and x square times negative 1 equals -x squsre. put x square on top of the roof. change the signs. the x cubed cancels out. and bring down 2x square from subtracting 3x square and -x square and bring down the x-9. Put 2x on top of the roof too and 2x times x equals 2x square and multiply by -1. U will have 2x square -2x square and -2x plus x which equals -1x cuz the 2x square cancels out. bring down the -9. Now i have -1x-9. Multiply by -1 and put -1 on the roof. -1x+1x cancels out. and -1 times -1 equals positive 1. So -9+1=8. U van do any further cause as soon as the last number is at the end of the roof and u cant go further, ur done dividing. so the answer is x square+2x-1/×-1 +8 as the remainder. hope i helped
