I think the answer is(-1,1)
Answer:
x = 4
PLS LOOK AT THE PIC I HAVE SENT YOU, HOPE THIS WILL HELP YOU!
Only 2 times. After that, there's only enough room in there for 21 more.
These facts all come about as a result of DIVISION. Divide 79 by 29 and you'll see.
<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>
Answer:
x = 12/5
Step-by-step explanation:
take the square of both sides
(x^2+49) = (x+5)^2
x^2 + 49 = (x+5) (x+5)
x^2+49= x^2 + 10x + 25
10x + 25 = 49
10x = 24
x = 12/5
