Answer: She sold 6.6kg of pears in the market.
Step-by-step explanation:
Weight of apples and pears at the farmer's market.=8.8 kilograms
Weight of apples = 1/4
which is = 1/4 x 8.8kg = 2.2 kg
Weight of Pears =Weight of apples and pears - Weight of apples
= 8.8kg- 2.2kg
= 6.6kg
Answer:
(x, y) = (-3, 2)
Step-by-step explanation:
Put the given value of y into the equation and solve for x.
... 7·2 +3x = 5
... 3x = -9 . . . . . . subtract 14
... x = -3 . . . . . . . divide by the x-coefficient
The solution (x, y) is (-3, 2).
Answer: a. $128.125
Step-by-step explanation:
The standard error of the mean is given by :
, where 
= population standard deviation , n= sample size.
Given: 
n= 256
Then, the standard error of the mean:-
Hence, option a. is correct.
y -
y1 = m (x - x1)
where m is the slope and (x1 , y1) is the point given
m = (y2-y1)\(x2-x1)
we have <span>(-5,-3) and (6,1)
so: m = (1- -3) / (6- -5) = (1+3)/(6+5) = 4/11
and the equation of the line is:
</span>y -
y1 = m (x - x1)
y-1 = 4/11 (x-6)
simplify:
y = 4/11 x - 24/11 +1
I hope that
