Answer:
-7/5
Step-by-step explanation:
3(x + 1) + 2 (x + 2) >0
(3x + 3) + (2x + 2 * 2) >0
(3x + 3) + (2x + 4) >0
= -7/5
Answer:
Mean = 0
Variance = 4/3
Standard Deviation √4/3
a= 0.9
Step-by-step explanation:
If X has a uniform distribution over [a,b] then its Mean is a+b/2 and variance is (b-a)²/12
Here a= -2 and b= 2
Now finding the mean = a+b/2=-2+2/2= 0
Variance = (b-a)²/12=( 2-(-2))²/12= 4²/12= 16/12= 4/3
Standard Deviation = √Variance= √4/3
b) = \int\limits^a_a {\frac{1}{a- (-a)} } \, dx
=1/2a[x]^a_-a= 2a/2a= 1 (applying the limits to the function)
P(−a<X<a) ==1/2 * 2a= a (applying the limits to the function)
P(−a<X<a)= 0.9
a= 0.9
In the given question the limits are -a to a . When we apply these in the above instead of [a,b] we get the above answer.
To solve this, you need to plug in your solution to your variable.
g² + 14g + 40
5² + 14(5) + 40
25 + 70 + 40
So, your area would be 135.
Out of your 4 options, you need to find out which dimensions create 130.
20 × 2 = 40
4 × 12 = 48
12 × 7 = 84
15 × 9 = 135
Your dimensions are 15ft by 9ft :)
Hope this helps!
Right triangle
Use Sohcahtoa
Given hypothenuse = 10
Adjacent = x
And angle degree of 52
You can use Cosine
Cos(52) = x/10
0.6156614753 = x/10
x = 6.156614753
Round to nearest tenth
Solution: 6.2
No it is not equivalent
please can i have a brainliest
