Mathematics
1 answer:
Studentka2010 [4]3 years ago
6 0

Step-by-step explanation:

Taking value of x= 4

16. 4 + 8 = <u>12</u>

17. 24 ÷ 4 = <u>6</u>

18. 3(4+4) = 3 × 8 = <u>24</u>

19. 5 × 4 = <u>20</u>

20. 30 - (5 × 4) = 30 - 20 = <u>10</u>

21.( 2 × 4 )+ 5 = 8 + 5 = <u>13</u>

22. 4 + 1 = <u>5</u>

23. 25 × 4 = <u>100</u>

24. 60 × 4 = <u>240</u>

25. (25×4) + 10 = 100 + 10 = <u>110</u>

What is the probability that a group of five friends all have different birthdays? Show all of your work for full credit.
patriot [66]

Answer: 0.98630136986

Step-by-step explanation:

There are 365 possible birthdays. The key to assigning the probability is to think in terms of complements: “Two (or more) people share a birthday” is the complement of “All people in the group have different birthdays.” Each probability is 1 minus the other. What is the probability that any two people have different birthdays? The first person could have any birthday (p = 365÷365 = 1), and the second person could then have any of the other 364 birthdays (p = 364÷365). Multiply those two and you have about 0.9973 as the probability that any two people have different birthdays, or 1−0.9973 = 0.0027 as the probability that they have the same birthday. If you have a group of five, it would mean your equation would have to be (p=360÷365)

Find the equation of the line with slope = 6 and passing through (6,43). Write your equation in the form y = m x + b .
gayaneshka [121]

Answer:

y = 6x + 7.

Step-by-step explanation:

Using the point-slope form of a line

y - y1 = m(x - x1)

m = 6, x1 = 6 and y1 = 43:

y - 43 = 6(x - 6)

y - 43 = 6x - 36

y = 6x - 36 + 43

y = 6x + 7.

An airplane descends 1.8 miles to an elevation of 6.75 miles. Find the elevation of the plane before its descent.
Mariana [72]

Answer: 8.55 miles

Step-by-step explanation:

Adding the totals given in the problem together:

1.8 miles + 6.75 miles = 8.55 miles.

Therefore, because we descended the plane and are looking for the previous height, we just add the descent to the elevation AFTER descent.
