Mathematics
1 answer:
nadya68 [22]3 years ago

Answer:

480,700 sets (first choice)

Step-by-step explanation:

If all 25 questions are different,

When order of selection counts:

P(25,7)

= 25!/(25-7)!

= 15511210043330985984000000/6402373705728000

= 2422728000

When order of selection does not count count:

C(25,7)

=25!/(7!*(25-7)!)

=15511210043330985984000000/(6402373705728000*5040)

= 480,700

Hope this helps, have a nice day.

What is the correct answer to this question?<br><br> F/2=5/8
ANTONII [103]

Answer:

F = 1.25

Step-by-step explanation:

All you would have to do is cross multiply, so our equations starts at \frac{F}{2} = \frac{5}{8}. We would now multiply F by 8 and 2 by 5. We now have 8F = 10. We can now divide both sides of the equation by 8 to get F = 1.25.

How do u do this problem: W/6+5/8=-1 3/8 <br> I got this answer: -1 53/64
Kobotan [32]
We have question
\frac{W}{6}+ \frac{5}{8} =-1 \frac{3}{8}    
\frac{W}{6} + \frac{5}{8} =- \frac{11}{8}  <span> /*8      (multiply both sides by 8)</span>
\frac{W8}{6} + \frac{5}{1} =- \frac{11}{1}  /*6      (multiply both sides by 6)
8W+5*6=-11*6      /-30 both sides
8W=-66-30
8W=-96
W=-12

Find each measure plz help
Rashid [163]

Answer:

m∠QRS = 52°

Step-by-step explanation:

From the given figure,

In right triangles ΔRQT and ΔRST,

QT = TS = 7.5 units [Given]

RT ≅ RT [Reflexive property]

ΔRQT ≅ ΔRST [By HL theorem of congruence]

Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]

m(∠QRS) = 2m(∠QRT)

               = 2×(26°)

               = 52°

The complement of an angle is $5^{\circ}$ more than four times the angle. what is the number of degrees in the measure of the an
Anna11 [10]

Answer:

  17°

Step-by-step explanation:

Let x represent the measure of the angle.

  (90 -x) = 5 + 4x . . . . the complement is 5° more than 4 times the angle

  85 = 5x . . . . . . . . . . add x-5 to both sides

  17 = x . . . . . . . . . . . . divide by 5

The measure of the angle is 17°.
