Answer:
The scale factor of water to flour represents the proportionality ratio, that is, [tex]k = \frac{7}{10}[/tex].
Step-by-step explanation:
According to the statement, we know that it exists a linear relationship between cups of water ([tex]w[/tex]) and cups of flour ([tex]f[/tex]). That is:
[tex]w = k\cdot f[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality ratio, measured in cups of water per cup of flour.
Therefore, the scale factor of water to flour represents the proportionality ratio, that is, [tex]k = \frac{7}{10}[/tex].
Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph.
Complete Question
Miniature dachshunds, a dog breed with very short legs, run at an average speed of 13 mph with a standard deviation of 1.6 mph. Labrador retrievers run at an average speed of 22 mph with a standard deviation of 2.8 mph. Both breeds' running speeds are Normally distributed. A miniature dachshund runs down a street at 14.8 mph. It is chasing a Labrador that is running 25 mph, use their z-scores to find which dog is running faster relative to its breed
Answer:
Miniature dachshunds is faster
Step-by-step explanation:
From the question we are told that
The speed of the Miniature dachshunds is [tex]x = 14.8 \ mph[/tex]
The mean for the Miniature dachshunds is [tex]\mu_1 = 13 \ mph[/tex]
The standard deviation for the Miniature dachshunds is [tex]\sigma_1 = 1.6 \ mp h[/tex]
The speed of the Labrador is [tex]y = 25 \ mph[/tex]
The mean for the Labrador is [tex]\mu_2 = 22 \ mph[/tex]
The standard deviation for the Labrador is [tex]\sigma_2 = 2.8 \ mp h[/tex]
Generally the z-score for the Miniature dachshunds is
[tex]z_1 = \frac{x- \mu_1 }{\sigma_1}[/tex]
=> [tex]z_1 = \frac{14.8 - 13 }{1.6}[/tex]
=> [tex]z_1 = 1.125[/tex]
Generally the z-score for the Labrador is
[tex]z_2 = \frac{x- \mu_2 }{\sigma_2}[/tex]
=> [tex]z_2 = \frac{25 - 22 }{2.8}[/tex]
=> [tex]z_2 = 1.071[/tex]
From the value obtained we see that [tex]z_1 > z_2[/tex] , hence miniature dachshund is faster

Answer:
as the last two months have a few minutes in a factory and we have a few minutes away and will also send the
28. The difference between two
numbers is 80. If the ratio of two
numbers is 3:5, find the
numbers *
Answer:
We set up 2 equations:
n - m = 80 so "n" is the larger number
A) n - m = 80
B) m / n = .6
A) n = 80 + m
B) m = .6 n so B) n = (5/3) m
We substitute B) into A)
(5/3) m = 80 + m
(2/3) m = 80
m = 1.5 * 80
m = 120
n = 200

What is an equation of the line that passes through the point (2, -5) and is parallel to the line
6x + y = 6?
The required equation of the line is 6x + y = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
First, we have to determine the slope of the line 6x + y = 6 by placing it into a slope-intercept form:
6x + y = 6 ⇒ y = -6x + 6
Therefore, the slope of the line is m = - 6
Since the required line passes through the point at (2, -5).
Let the line (y - y₁) = m(x -x₁ )
Here x₁ = 2, y₁ = -5
Substitute the values in the equation,
So, y - (-5) = -6(x - 2)
⇒ y + 5 = -6x + 12
⇒ 6x + y = 7
Hence, the required equation of the line is 6x + y = 7 which is parallel to line 6x + y = 6 and passes through the point at (2, -5).

What is the value of x?
Enter your answer in the box.
Answer:
X = 40
Step-by-step explanation:
{ 2 (x + 10)} = (3x - 30)
2x + 10 = 3x - 30
10 = 3x - 2x - 30
10 + 30 = 1x
40 = 1x
X = 40
Which linear equation represents the graph?
Answer:
wheres the image?
Step-by-step explanation:
what is the answer to this..√25x+10=15
Answer:
x = 1.
Step-by-step explanation:
√25x + 10 = 15
√25x = 15 - 10
√25x = 5
squaring both sides:
(√25x)^2 = (5)^2
25x = 25
hence x = 1.

If the population of a study is finite and just covers only a small set of data and the time and cost of the study is of no concern to the one who is conducting the study then it is better to take samples rather than conduct the study over the whole population
Answer:
False
Step-by-step explanation:
The above statement is not correct since the time and cost of the study is of no concern to the one who is conducting the study, The person conducting the study having ample time and resource, means that it would be better for the person to expand the scope of the study by conducting it over the whole population because that will give a more accurate result rather than conducting the study over a few samples .

The cost of the family’s cell phone plan rose from $130 to $194 when they added a phone for their daughter. What was the percent of increase?
Answer:
49%Step-by-step explanation:
Step one:
initial price=$130
final price=$194
Step two:
we know that the percent increase is given as
% increase= final-initial/initial
substituting we have
% increase= 194-130/130*100
% increase= 64/130*100
% increase= 0.49*100
% increase= 0.49*100= 49%
therefore the percent increase is 49%
