Answer:
Any equation of a line having a slope of 1/2.
Step-by-step explanation:
It appears that the question gives answer choices and this problem could have many solutions, but parallel lines have equal slopes. The slope of this line is 1/2 since it is in y=mx+b form where m is the slope. So a few examples of equations of lines parallel to the given equation would be y = 1/2x - 5 or y = 1/2x + 10 etc.
Answer:
The probability that between 64 and 90 of them read the ingredients listed on a product's label is 0.82.
Step-by-step explanation:
We know the proportion of the population, that is π=0.28.
The standard deviation for this sampling distribution is
The value 64 represents a proportion of p=64/256=0.25, and the value 90 represents p=90/256=0.35.
With these values, we can calculate the z-values.
The probability that between 64 and 90 read the ingredients is:
The probability that between 64 and 90 of them read the ingredients listed on a product's label is 0.82.
Answer:
x = 10
Step-by-step explanation:
x = 4 + (4x-4) ^ (1/2)
First, we rewrite the expression:
x = 4 + (4x-4) ^ (1/2)
x = 2 (2+ (x-1) ^ (1/2))
x = 4 + 2 (x-1) ^ (1/2)
From here we get a solution for x = 10
To check it we substitute x = 10 in the expression:
10 = 4 + 2 (10-1) ^ (1/2)
10 = 4 + 2 (9) ^ (1/2)
10 = 4 + 2 (3)
10 = 4 + 6
10 = 10
Answer:
The solution is:
x = 10
