Answer:
Order of Operations ( PEMDAS)
First you do Parentheses
Second you do Exponents before Multiplying and stuff
Then you Multiply or divide before addition and subtraction
Step-by-step explanation:
Answer: solanka 6-procentowa=3 kg
solanka 9-procentowa = 6 kg
Step-by-step explanation:
Let solanka 6-procentowa=x kg
Let solanka 9-procentowa = y kg
So x+y=9
=> x=9-y (1)
6%=0.06 9%=0.09 8%=0.08
So pure salt is 0.06*x +0.09*y= 9*0.08 (2)
Lets put 9-y instead x in (2)
0.06*(9-y) +0.09*y=0.72
0.54-0.06*y +0.09*y=0.72
0.03*y=0.18
y=6kg => x=9-y => x=9-6=3 kg
Answer:
the answer is 14:1
Step-by-step explanation:
Answer:
value = 8
Step-by-step explanation:
when a paired-samples t test is used by this researcher we will write out the hypothesis as follows
H0: μd ≤ 8 ( null )
Ha: μd > 8 ( alternate )
Given the above Hypothesis
If a paired-sample T test is used by the researcher the value that would be at the center of the comparison will be 8
Answer:
y = -1/2x + 5
Step-by-step explanation:
To get the perpendicular line first, take the negative reciprocal of the slope.
2 -> -1/2
So far, the equation is y - -1/2x ± b. (since we are using mx + b)
Since you want the point (4, 3) to cross over the line, we substitute values in.
3 = -1/2(4) + b
3 = -2 + b
b = 5
Your equation that fits the answer is -1/2x + 5.
Your welcome!
