You take out the common values
slope = -2/5; y-intercept = 0
Answer:
Y= -2/5X
Step-by-step explanation:
the equation is y=mx + b
slope: -2/5x
y- intercept: 0
all you do is combined your slope and y-intercept together: Y= -2/5X , you dont need to add +0 because it gonna just still be the same as y= - 2/5x
Y= -2/5X or y= -2/5x + 0 is the same so it can be any of these 2 that you pick but the correct way is y= -2/5x
Which expression is not equivalent to -2(4 - 3x)+(5x-2)? A)11x-10.
B)-8+11x-2
C) -8-11x-2.
D) -8+6x+5x-2
Answer:
C) -8-11x-2.
Step-by-step explanation:
First solve the expression,
-2(4 - 3x)+(5x-2) = 11x-10
A) 11x-10 = 11x-10
B) -8+11x -2 = 11x-10
C) -8-11x-2 does not equal 11x-10. Instead -8-11x-2 = -11x-10
D) -8+6x+5x-2 = 11x-10
Hope this helped! :)

Solve the system of equations by elimination:
4b + 13c = -24
12b - 50 = 16
Hint: When you have variables that are not x and y, put them in alphabetical order in your ordered pair EX (b,c)
no solution
(1/2,-2)
(1/3, 4
(2,-2)
Answer:
B (1/2,-2)
Step-by-step explanation:
4b + 13c = -24 --(1)
12b - 5c = 16 --(2)
(1)x3
12b + 39c = -72 --(3)
(3)-(2)
12b + 39c - 12b + 5c = -72-16
c = -2
Sub c = -2 into (1)
4b = -24 - 13(-2)
b = 1/2
Answer:
b

Step-by-step explanation:
While growing bacteria in a laboratory Petri dish, a scientist notices the number of bacteria over time. The observations are shown in the table.
Number of bacteria
Number of minutes
from initial state
0 4
5 128
10 4096
15 131072
What function can be used to describe the number (n) of bacteria after 2 minutes?
Answer:
The function that can be used to describe the number (n) of bacteria after 2 minutes is;
[tex]P = 4 \cdot e^{\left(\dfrac{ln(32)}{5} \times 2\right)} \approx 4 \cdot e^{\left(0.693\times 2\right)}[/tex]
Step-by-step explanation:
The data in the table are presented as follows;
Number of bacteria; 4, 128, 4,096, 131,072
Number of minutes from initial state; 0, 5, 10, 15
The general equation for population growth is presented as follows;
[tex]P = P_0 \cdot e^{r\cdot t}[/tex]
Where;
P = The population after 't' minutes
P₀ = The initial population
r = The population growth rate
t = The time taken for the growth in population numbers
At t = minutes. we have;
[tex]4 = P_0 \cdot e^{r\times0} = P_0[/tex]
∴ P₀ = 4
At t = 5, we have;
[tex]128 = 4 \cdot e^{r\times 5}[/tex]
[tex]\therefore e^{r\times 5} = \dfrac{128}{4} = 32[/tex]
[tex]ln\left(e^{r\times 5}\right) = ln(32)[/tex]
∴ r × 5 = ㏑(32)
r = ln(32)/5 ≈ 0.693
The number (n) of bacteria after 2 minutes is therefore;
[tex]P = 4 \cdot e^{\left(\dfrac{ln(32)}{5} \times 2\right)} \approx 4 \cdot e^{\left(0.693\times 2\right)}[/tex]

Say you want to know if boys are more likely than girls to "wait for their missionary". You take a random sample of 57 males and 63 females, all of whom are in a relationship with someone who just left on a mission. You follow-up with them after the mission of their significant other returned home to determine if their relationship continue after the mission. What type of analysis is best suited for this study
Answer: 2 independent sample test of proportions
Step-by-step explanation:
The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.
In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.
The kind of analysis that would be most adequate for the given study:
Test of 2 Independent Proportions.
Independent Proportions
The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.
In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.
In the given situation, the samples of males and females are random and permitted to stay free("continue after the mission") and evaluated after a time to take the deduction.

Three square flower beds with side of 2m are dug in a rectangular piece of land whose length is 5.2 m and width is 4.8 m. What is the area of the remaining land?
Answer: 12.96 m²
Step-by-step explanation:
The area of the piece of land that the flower beds were dug in is:
= Length * width
= 5.2 * 4.8
= 24.96 m²
The flower beds were 3 in number and all had the shape of a square.
Their area is:
= 3 * (Length * width)
= 3 * ( 2 * 2)
= 3 * 4
= 12 m² for all three flower beds
Remaining land:
= 24.96 - 12
= 12.96 m²
