-1(x + 5) = -x - 5
-1(x - 5) = -x + 5
-(x + 3) = -x - 3
-(x - 3) = -x + 3
Answer:
2330
Step-by-step explanation:
In rounding nearest 10,
If the ones place digit is 5 or more then 5 then we round the number to upper 10, while if the ones place digit is less than 5 then we round the number to lower 10,
For example : 34 ≈ 30 while 36 ≈ 40,
Now, given expression,
961 + 27.8 + 693.0 + 573 +76.4
By the above statement 961≈ 960, 27.8 ≈ 30, 693.0 ≈ 690, 573 ≈ 570 and 76.4 ≈ 80,
Hence, 961 + 27.8 + 693.0 + 573 +76.4 = 960 + 30 + 690 + 570 + 80 = 2330.
Answer:
0.353
Step-by-step explanation:
We have been given that a history class is comprised of 7 female and 10 male students.
We will use combinations to solve our problem.
We can choose 6 female students out of 7 female students in ways.
We can choose 7 male students out of 10 male students in ways.
So the number of ways that 6 female and 7 males can be chose is: 7*120 = 840.
Now let us find ways in which 13 students can be chosen from 17 students as:
Now let us substitute our values in probability formula.
Therefore, the probability of selecting 6 female students and 7 male students is 0.353.
Answer:
52
Step-by-step explanation:
Given the the equation h(t) =- where t is the time in second
So to find the ball's maximum height we can apply the vertex formula:
t=
to find the "x" value of the vertex, then plug that value into the original equation as a substitute for "x".
Standard quadratic form is:
=> a=15, b=30 in our given equation
<=> t =
When t =-1 we have h(t) = = 52
So the ball's maximum height is: 52
Hope it will find you well.
