What multiplies to -26 and adds to -25
Answer:
1 and -26
Step-by-step explanation:
Consider the factors of 26 (because the two numbers have to multiply to -26). These are: 1 and 26, 2 and 13.
2 and 13 cannot be added or subtracted from one another to get -25, but 1 and 26 can, or rather 1 and -26.

The rule for taking the square root of a number factored into primes is if they are in pairs, take one of the pairs out of the root sign and throw the other one away. Any odd number of primes always has one prime left under the root sign.
3√2 - √2
Root 2 is a common factor on either side of the minus sign.
√2*(3 -1)
√2 * 2

REPOST PLEASE I NEED HELP I could really use some help with this guys:)................................................................................................................................................................................................................................................Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.
Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.

Use the drop-down menus to explain how to name the ordered pair for Point A on the grid. First quadrant grid with point A at (2,4) labeled Follow the grid line from Point A down to the x-axis. The x-coordinate is . Next, follow the grid line from Point A to the y-axis. The y-coordinate is . The ordered pair is .
Answer:
Vertical, 2, horizontal, and (2,4).
Step-by-step explanation:
Follow the vertical grid line from Point A down to the x-axis. The x-coordinate is 2. Next, follow the horizontal grid line from Point A to the y-axis. The y-coordinate is 4. The ordered pair is (2,4).Solve the given formula for the indicated variable:
z = xy + 2ab for a.
Answer:
If we solve for a
2ab=z–xy
a = z–xy/(2b)

Amy deposits S500 into an account that pays simple interest at a rate of 5% per year. How much Interest will she be paid in the first 4 years?
Answer:
She will be paid $100 in interest in the first 4 years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
Amy deposits $500 into an account that pays simple interest at a rate of 5% per year.
This means that [tex]P = 500, I = 0.05[/tex]
How much Interest will she be paid in the first 4 years?
This is E when [tex]t = 4[/tex]. So
[tex]E = P*I*t = 500*0.05*4 = 100[/tex]
She will be paid $100 in interest in the first 4 years.
The following playing cards are used in a game. What is the probability of not selecting a prime number?
1,2,3,4,5,6,7
Answer:
3/7
Step-by-step explanation:
1,2,3,4,5,6,7
The word problem is asking the PROBABILITY OF NOT SELECTING A PRIME NUMBER.
PROBABILITY: THE LIKELIHOOD OF AN EVENT.
There are 7 numbers in this data set. Of the seven numbers, four are prime numbers, three of them are not.
Therefore, the probability of not selecting a prime number is 3 in 7, or 3 out of 7 (3/7).

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains.
If he has 9 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
9514 1404 393
Answer:
90
Step-by-step explanation:
1 dekameter is 10 meters, so each of Glenn's 9 pieces of ribbon can be cut to make 10 1-meter pieces.
9 × 10 m = 90 m . . . . length of available ribbon
(90 m)/(1 m/piece) = 90 pieces
Glenn can cut 90 1-meter pieces from the ribbon he has.

Two expressions are shown below:
5(4a+7u)
20a+35u
Are these expressions equivalent? Explain why or why not.
Answer:
yes
Step-by-step explanation:
yes because 5 times 4 a
is 20 a and 5 times 7u is 35
Answer:
Yes
Step-by-step explanation:
If you were to give the variables a number value such as a=2 u=3
5(4*2+7*3)=145
20*2+35*3=145
They are equivalent

Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your dog now?
Answer:
Dog is 2 years old
Step-by-step explanation:
Let dog's age = d
Let friend's age = f
Your dog is 8 years younger than your friend:
d +8 = f
In 2 years, your friend will be three times as old as your dog:
3(d+2) = (f+2)
3d+6 = f+2
3d = f - 4
(sub in f=d+8 from above)
3d = f - 4
3d = d+8 - 4
2d = 4
d = 2
The difference between an observational study and an experiment is that
O in an observational study, only one group is studied, and in an experiment, two groups are studied.
in an observational study, the researchers do not control treatment, and in an experiment, they do.
• in an experiment, cause-and-effect is analyzed, and in an observational study, it is not.
®
in an experiment, one group is studied over a short period of time, and in an observational study, the group is
studied over a longer period of time.
Answer:
I think it's the last one! In an experiment, one group is studied over a short period of time---

Of the 650 student at westmoreland junior high, 80% will attend the field trip. How many student will attend the field trip?
Answer:
520 students will attend
Step-by-step explanation: sorry forgot to explain. An easy way to do it is to multiply the number your using (650) x the percentage (80%) here's an example: 60% of 1,005 multiply 60 x 1005 = 603
603 is 60% of 1005. ;D
Answer: 520
Step-by-step explanation: A way to find even percentages (10%, 20%, etc) is to take 10% of the original number, in this case, it would be 65, and then multiply it by the first number in the percentage. In this case, it would be;
65 x 8 = 520
