x and y i think, I haven't done that in a long time.
Answer:
0.9962
Step-by-step explanation:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

μ = 20.66°C, σ = 2°C
For x < Singapore temperature, i.e. x < 26

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
Use rates, so 8 garden hoses over 18 hours
then find the how many hours one garden house can fill up by doing this = 18/8 you divide the 8 for both sides which is about 2.25/1
so then you times 9 which is about 20/9 hoses
your answer is 20
Answer:

Step-by-step explanation:
The general form of a quadratic polynomial is given by:
(1)
You have the following polynomial:
(2)
In order to complete the factorization you can use the quadratic formula, to obtain the roost of the polynomial. The quadratic formula is given by:
(3)
By comparing the equation (1) with the equation (2) you obtain:
a = 3
b = -10
c = 8
Then, you replace these values in the equation (3):

Then, the factorization of the polynomial is:

Answer:
Yes, vectors u and v are equal.
Step-by-step explanation:
We need to check whether vectors u and v are equal or not.
If the initial point is
and terminal point is
, then the vector is

Vector v with an initial point of (-5,22) and a terminal point of (20,60).

..... (1)
Vector u with an initial point of (50,120) and a terminal point of (75,158).

.... (2)
From (1) and (2) we get

Therefore, vectors u and v are equal.
