Answer:
0.30
Step-by-step explanation:
P(x ≤ -3) = P(x=-3) + P(x=-5)
P(x ≤ -3) = 0.13 + 0.17
P(x ≤ -3) = 0.30
Answer:
x+8 =343
Step-by-step explanation:
5 ( x+8) ^ 1/3 = 35
Divide each side by 5
5/5 ( x+8) ^ 1/3 = 35/5
( x+8) ^ 1/3 = 7
Cube each side
( x+8) ^ 1/3 ^3= 7^3
x+8 =343
Answer: No
Solution:
Substitute the values of x & y into the first equation
6 -(-1) = 3
6 + 5 is NOT equal to 3
Therefore we can say this is not true
For this to be true, when substituting the values of x & y, the equation must be true for BOTH equations. Since it’s not true for the first equation it doesn’t matter if it’s true or not for the other equation.
I hope this helps!
Answer:
16 runners finished the race under 13 minutes.
Step-by-step explanation:
If you look at the green bars that are 11:00-12:59, 9:00-10:59 and 7:00 to 8:59 you will notice they are all under 13, The number of runners that finished it in 11:00-12:59 are 8, The number of runners that finished it in 9:00-10:59 are 6 and The number of runners that finished it in 7:00-8:59 are 2. 8+6+2 = 16
Answer:
x + 7
Step-by-step explanation:
x2 + 4x − 21
set equal to 0
x2 + 4x − 21 = 0
factor
(x - 3) (x + 7)
x2 + 11x + 28
set equal to 0
x2 + 11x + 28 = 0
factor
(x + 4) (x + 7)
