Answer:
B)
15 ≥ 3x + y
8 ≥ x + y
Step-by-step explanation:
Strawberries= 3x
Blueberries= y
At least symbol= ≥
15 ≥ 3x + y (Plans to spend AT LEAST $15 so this has to be 15 ≥)
8 ≥ x + y (Plans to spend AT LEAST 8 pints so this has to be 8 ≥)
Greatest to least:
0.836, 0.683, 0.386, 0.3
Answer:
Its not a real number for the square roots of negative number
its not possible...
= -2 x -2 no... 2 x 2 no..... -2 x 2 yea but thats not square root anymore...

Answer:
The pooled variance for the two samples is 90
Step-by-step explanation:
Here in this question, we are interested in computing the pooled variance for the two given samples.
From the question;
n1 = 9
ss1 = 710
n2 = 6
ss2 = 460
The pooled variance can be calculated using a mathematical formula as shown below;
S^2 =( ss1 + ss2)/(n1 + n2 -2)
where S^2 refers to the pooled variance of both samples.
Plugging the values into the equation, we have ;
S^2 = (710 + 460)/9 + 6 -2 = 1170/13 = 90
