Unit rate for $6.50 for 3 1/4 pounds of grapes
The unit rate for $6.50 for 3 1/4 pounds of grapes is 2 pounds
How to determine the unit rate for $6.50 for 3 1/4 pounds of grapes?The given parameters are
Amount = $6.50
Volume = 3 1/4 pounds
The unit rate of grapes can be calculated using the following formula
Unit rate = Amount/Volume
Substitute the known parameters in the above equation
So, we have
Unit rate = 6.50/(3 1/4)
Express 3 1/4 as a decimal
So, we have
Unit rate = 6.50/(3.25)
Evaluate the quotient
So, we have
Unit rate = 2
Hence, the unit rate for $6.50 for 3 1/4 pounds of grapes is 2 pounds

Answer: $2.00 /lb
Step-by-step explanation:
The other math calculation answers have errors in the numbers. It's supposed to say:
$6.50 divided by 3 (1/4)
3 (1/4) = 13/4
$6.50 × 4 = 26 then 26/13 = $2.00 per pound

Explain in your own words how to find the equation of the horizontal line that passes through (3.5, 4.5) (HELP PLEASE ITS A QUIZZ)
Answer:
y=4.5
Step-by-step explanation:
You just have to remember that the equation of a horizontal line is a constant function, meaning that no matter what values are entered into the system, the answer for Y will always be the same. So in this case the function will be y=mx+b, since m or the slope in a horizontal line is 0 "x" will also be 0, so y=b, in this case as we can see in the point we are given b=4.5, so y=4.5

Bottles filled by a certain machine are supposed to contain 12 oz of liquid. In fact the fill volume is random with mean 12.01 oz and standard deviation 0.35 oz.a) What is the probability that the mean volume of a random sample of 144 bottles is less than 12 oz?b) If the population mean fill volume is increased to 12.03 oz, what is the probability that the mean volume of a sample of size 144 will be less than 12 oz?
Answer:
a
[tex]P(X < 12) = 0.3660[/tex]
b
[tex]P(X < 12) = 0.1521[/tex]
Step-by-step explanation:
Considering question a
From the question we are told that
The mean is [tex]\mu = 12.01 \ oz[/tex]
The standard deviation is [tex]\sigma = 0.35 \ oz[/tex]
The standard error of mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{0.35}{\sqrt{144} }[/tex]
=> [tex]\sigma_{x} = 0.02917[/tex]
Generally the probability that the mean volume of a random sample of 144 bottles is less than 12 oz is mathematically represented as
[tex]P(X < 12) = P(\frac{X - \mu }{\sigma_{x}} < \frac{12 - 12.01 }{0.02917 } )[/tex]
[tex]\frac{X -\mu}{\sigma_{x} } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 12) = P(Z < -0.3425 )[/tex]
From the z table the area under the normal curve to the left corresponding to -0.3425 is
[tex]P(X < 12) = P(Z < -0.3425 ) = 0.3660[/tex]
=> [tex]P(X < 12) = 0.3660[/tex]
Considering question a
From the question we are told that
The mean is [tex]\mu = 12.03 \ oz[/tex]
Generally the probability that the mean volume of a random sample of 144 bottles is less than 12 oz is mathematically represented as
[tex]P(X < 12) = P(\frac{X - \mu }{\sigma_{x}} < \frac{12 - 12.03 }{0.02917 } )[/tex]
[tex]P(X < 12) = P(Z < -1.0274 )[/tex]
From the z table the area under the normal curve to the left corresponding to -1.0274 is
[tex]P(X < 12) = P(Z < -1.0274 ) =0.1521[/tex]
=> [tex]P(X < 12) = 0.1521[/tex]

How can you find the slope of the line that passes through the points (0, 0) and (2, 4)? Explain.
The slope of the line that passes through the points (0, 0) and (2, 4) is m = 2
The slope(m) of the line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
For the line that passes through the points (0, 0) and (2, 4)
x₁ = 0, y₁ = 0, x₂ = 2, y₂ = 4
Substitute x₁ = 0, y₁ = 0, x₂ = 2, y₂ = 4 into the equation [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{y_2-y_1}{x_2-x_1} \\\\m = \frac{4-0}{2-0} \\\\m = \frac{4}{2} \\\\m = 2[/tex]
The slope of the line that passes through the points (0, 0) and (2, 4) is m = 2
