The slope of the line that represents the data Nicholas collected is -63, and the y-intercept is 825. Explain what these represent in the context of the situation. Remember that x is the number of days, and y is the number of canned goods. The slope of the line that represents the data Nicholas collected is -63, and the y-intercept is 825. Explain what these represent in the context of the situation. Remember that x is the number of days, and y is the number of canned goods.
Answers
Answer:
slope of - 63 in the context means, as the number of days increases by 1, The number of canned goods there is 63 reduction in yhe number of canned goods.
An intercept value of 825 means the Number of canned goods even when the number of days is 0.
Step-by-step explanation:
Given that:
Slope = - 63
y intercept = 825
x = number of days
y = number of canned goods
From the general form of a linear model :
y = mx + c
m = slope / gradient ; c = intercept
Hence,
y = - 63x + 825
A slope of - 63 in the context means, as the number of days increases by 1, The number of canned goods there is 63 reduction in yhe number of canned goods.
An intercept value of 825 means the Number of canned goods even when the number of days is 0.

Answer:
For the first one it is y = -5x because for it to be direct it can't have a b-intercept. it must start at 0.
Second question: y2 - y1/x2 - x1
13-(-8)/(-4)-3
21/(-7)
-3 is the slope
y= -3x + b
13 = -3(-4) + b
13 = 12 + b
12 - 13 = b
b = -1
y=-3x-1
0 = -3x - 1
1 = -3x
1/-3 = -3x/-3
x= -1/3
y=-3x-1
y=-3(0)-1
y= -1
The answer to the 3rd question is y = 1x + 2 because the rise over run is one and the line crosses the y-intercept at 2.
I am not sure if these answers are correct.

The number of students, SSS, serviced by the school system in the town of Emor, ttt years from 2000 can be modeled by the function S(t)=10{,}000(1.1)^t. The number of classrooms, C, in the town of Emor, t years from 2000 can be modeled by the function C(t)=450+40t. Let D be the average number of students per classroom in Emor's school system t years from 2000.
Answers
Answer:
The formula of D (t) is .1000.(1.1)/45+4t
Step-by-step explanation:
The expression representing the number of students serviced by the school system in the town of Emor, t years from 2000 is:
And the expression representing the number of classrooms in the town of Emor, t years from 2000 is: s(t)=10,000.(1.1)^t
The expression D (t) represents the average number of students per classroom in Emor's school system t years from 2000.
Then the average number of students per classroom can be computed by:
C(t)=450+40t.
Average number of students/classroom = Number of students/Number of classrooms so the answer is D (t) .1000.(1.1)/45+4t
Thus,the formula of D (t) is .
1/2z+6=3/2(z+6) need the answer asap
Answers
Answer:
z = -3
Step-by-step explanation:
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex](z+6)
Expand and cancel out brackets.
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex]z +
Simplify.
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex]z + 9
Isolate x and numbers.
[tex]\frac{3}{2}[/tex]z - [tex]\frac{1}{2}[/tex]z = 6-9
Simplify.
[tex]\frac{2}{2}[/tex]z = -3
z = -3
Answer:
z=−3
Step-by-step explanation:
1/2*z+6-(3/2*(z+6))=0
Simplify 3/2
1 3
((— • z) + 6) - (— • (z + 6)) = 0
2 2
Simplify 1/2
Rewrite the whole as 6.1 Pull out like factors :
-2z - 6 = -2 • (z + 3) a fraction using 2 as the denominator.
-z - 3 = 0
7.1 Solve : -z-3 = 0
Add 3 to both sides of the equation :
-z = 3
Multiply both sides of the equation by (-1) : z = -3
A research team is testing whether a fuel aditive increases a car's gas mileage. The maker of the additive claims that the additive will increase a car's gas mileage by at least 6 mpg. Among 25 cars that were treated with the additive, the average increase in mileage was 5.3 mpg with a standard deviation of 1.8 mpg. The research team found the z-score to be -1.94. Is there enough evidence to reject the company's evidence?
Answers
Answer:
Yes there is sufficient evidence to reject the company's evidence
Step-by-step explanation:
From the question we are told that
The sample size is n = 25
The mean is [tex]\= x = 5.3 \ mpg[/tex]
The standard deviation is [tex]\sigma = 1.8 \ mpg[/tex]
The z-score is z = -1.94
The null hypothesis is [tex]H_o : \mu = 6 \ mpg[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 6[/tex]
Generally the p-value is mathematically evaluated as
[tex]p-value = 2 * P( Z <-1.94)[/tex]
From the z table the area under the normal curve to the left corresponding to -1.94 is
[tex]P( Z <-1.94) = 0.02619[/tex]
=> [tex]p-value = 2 * 0.02619[/tex]
=> [tex]p-value = 0.052[/tex]
Let assume the level of significance is [tex]\alpha = 0.05[/tex]
Hence the [tex]p-value > \alpha[/tex] this mean that
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence to reject the company's evidence
