On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, negative 7) and (0, 2). Everything to the left of the line is shaded. Which linear inequality is represented by the graph?
Answer:
y>3x+2
Step-by-step explanation:
1. use y2-y1/x2-x1 to find the slope (3)
2. since the y-intercept is already give as (0,2) we have the equation y=3x+2
3. finally since the left side is shaded, that would mean everything greater than that equation can equal y therefore y>3x+2

If 3(c+d) = 5 and c = 1, what is the value of c + d?
Answer:
c+d = 5/3
Step-by-step explanation:
3(c+d) = 5
Divide each side by 3
3/3(c+d) = 5/3
c+d = 5/3
Answer:
3(1+d)=5
3×1=3
3×d=3d
:3+3d-5
3d-2
3d=2 (Devide both sides by 3)
d=2/3

The median of the data in dot plot 1 is

2.
The mode of the data in dot plot 1 is less
than the mode of the data in dot plot 2.
Answer:
the answer is b. The mode of the data in dot plot 1 is less than the mode of the data in dot plot 2.
Step-by-step explanation:
In the dot plots 1 and 2, the statement which is true is that the mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.
What is dot plot?The dot plot is the way oif representation of the data. This data is plooted in the form of points or dots over an x-y axis. The dot polt is also known as the strip plot.
Dot plot 1 is the top plot. The value of it are as,
2,3,4,5,5,6,6,6,6,7,7,7,8,8,9,10
Dot plot 2 is the bottom plot. The value of it are as,
1,2,2,3,3,4,4,4,5,5,5,6,6,7,8,9
The options given in the problem are,
The range of the data in dot plot 1 is less than the range of the data in dot plot 2-Range is difference between the highest and lowest value. The range of the first dot plot is,
[tex]r_1=10-2=8[/tex]
The range of the Second dot plot is,
[tex]r_2=9-1=8[/tex]
Range of dot plots are equal.
The mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.Mean of the dot plot one is 6.1875 and mean of the dot plot second is 4.625.
The median of the data in dot plot 1 is equal to the median of the data in dot plotThe median of the data in dot plot 1 is 6 and the median of the data in dot plot is 4.5. Thus they are not equal.
The mode of the data in dot plot 1 is less than the mode of the data in dot plot 2.The mode of the data in dot plot 1 is 6 and the mode of the data in dot plot 2 is 4 and 5. Thus this is not correct option.
Hence, in the dot plots 1 and 2, the statement which is true is that the mean of the data in dot plot 1 is greater than the mean of the data in data plot 2.

Step-by-step explanation:
The median number of part-time employees at fast-food restaurants in a particular city was known to be 18 last year. City officials think the use of part-time employees may be increasing. A sample of nine fast-food restaurants showed that seven restaurants were employing more than 18 part-time employees, one restaurant was employing exactly 18 part-time employees, and one restaurant was employing fewer than 18 part-time employees. Can it be concluded that the median number of part-time employees has increased
Answer:
It can be concluded that the median number of part-time employees has increased hence we will reject the null hypothesis ( H0 : p = 0.5 )
Step-by-step explanation:
Test using α = 0.5 to determine whether the median number of part-time employees has increased
number of restaurants with more than 18 part-time employees = 7 ( + sign )
number of restaurants with less than 18 part-time employees = 1 ( - sign )
number of restaurants with exactly 18 part-time employees = 1
first step : ( state the null and alternate hypothesis )
Null hypothesis : ( H0) : median ≤ 18
Alternate hypothesis : ( Ha ) : median ≥ 18
The size of the sample ( n ) can be considered to be 8 because
number of restaurants with more than 18 part-time employees = 7 ( + sign )
number of restaurants with less than 18 part-time employees = 1 ( - sign )
Hence the actual hypothesis that should be tested will be :
H0 : p = 0.5
Ha : p ≠ 0.5
Next apply the binomial distribution to determine the number of + signs
= nP = 8 ( 0.5 ) = 4 + signs ( right tailed test i.e. upper tail of the binomial distribution )
determine the P ( ≥ 7 ) + signs in order to obtain the p-value of this right tailed test ( using the binomial probability table )
P ( ≥ 7 )+ signs = p(7) +signs + p(8)+signs
= 0.0313 + 0.0039 = 0.0352
Hence the P-value = 0.0352 is < 0.05 hence we will reject the Null hypothesis ( H0 : p = 0.5 )
hence It can be concluded that the median number of part-time employees has increased
The true statement is that, the median number of part-time employees has increased
The given parameters are:
[tex]\mathbf{n_1 = +7}[/tex] ---- restaurants with more than 18 part-time employees[tex]\mathbf{n_2 = -1}[/tex] ---- restaurants with less than 18 part-time employees [tex]\mathbf{n_3 = 1}[/tex] ---- restaurants with exactly 18 part-time employeesUsing a 0.5 test of significance, the null and the alternate hypotheses are:
Null hypothesis : [tex]\mathbf{H_0 : p= 0.5}[/tex]Alternate hypothesis : [tex]\mathbf{H_a : p \ne 0.5}[/tex]The sample size (n) is calculated using
[tex]\mathbf{n =n_1 -n_3}[/tex]
So, we have:
[tex]\mathbf{n =7 --1}[/tex]
[tex]\mathbf{n =8}[/tex]
The mean of the distribution is:
[tex]\mathbf{\bar x = np}[/tex]
This gives
[tex]\mathbf{\bar x = 8 \times 0.5}[/tex]
[tex]\mathbf{\bar x = 4}[/tex]
Using the right tailed test, we calculate the probability that a restaurant has more than 7 part-time employees.
This is calculated as:
[tex]\mathbf{P(x \ge 7+) = P(x = 7+) + P(x = 8+)}[/tex]
Using the binomial probability table, we have:
[tex]\mathbf{P(x \ge 7+) = 0.0313 + 0.0039 }[/tex]
[tex]\mathbf{P(x \ge 7+) = 0.0352}[/tex]
By comparison,
When the p-value is less than the level of significance, then we will reject the Null hypothesis
Hence, it can be concluded that the median number of part-time employees has increased

Solve for the system of equations using elimination
Answer:
(-1,5)
Step-by-step explanation:
Solve the following system:
2 y + x = 9 | (equation 1)
2 y + 3 x = 7 | (equation 2)
Subtract equation 2 from equation 1:
( 2 y + x ) - ( 2 y + 3 x ) = 9 - 7
- 2 x = 2
x = - 1
Substitute into question 1:
2 y - 1 = 9
y = 5
Answer: x = -1 , y = 5
