Step-by-step explanation:
Suppose that when a system of linear equations is graphed, one line completely overlaps the other line. Which statement is correct?
The system of equations has one solution because the lines intersect at one point.
The system of equations has one solution because the lines do not intersect at only one point.
The system of equations does not have only one solution because the lines intersect at one point.
The system of equations does not have only one solution because the lines do not intersect at only one point.
Answer:
The system of equations does not have only one solution because the lines do not intersect at only one point.
Step-by-step explanation:
If the lines are covered by each other, they intersect at all the points they overlap on. So, there is more than on solution.
The following statement is correct.
The system of equations does not have only one solution because the lines do not intersect at only one point.
The following information should be considered:
In the case when the system of linear equations is graphed and one line is overlap to the other one.So here the system of equation contains more than one solution as the lines are not intersected at only one point but more than one point.Learn more: brainly.com/question/17429689

The joint relative Frequency of students who do not like to run and enjoy swimming, based on the given two-way frequency table, is approximately 62.16%.
The joint relative frequency of students who do not like to run and enjoy swimming, we need to find the intersection of the row and column corresponding to those categories in the two-way frequency table.
Given the following information from the table:
Likes running: 28
Does not like running: 46
Column totals: 74
Enjoys swimming: 62
Enjoys cycling: 90
Row totals: 110
The joint relative frequency, we divide the number of students who do not like running and enjoy swimming by the total number of students:
Joint relative frequency = (Number of students who do not like running and enjoy swimming) / (Total number of students)
From the table, the number of students who do not like running and enjoy swimming is given as 46.
Total number of students is given as 74.
Joint relative frequency = 46 / 74
Calculating this value, we find that the joint relative frequency is approximately 0.6216, which is equivalent to 62.16%.
Therefore, the joint relative frequency of students who do not like to run and enjoy swimming is approximately 62.16%.
In conclusion, the joint relative frequency of students who do not like to run and enjoy swimming, based on the given two-way frequency table, is approximately 62.16%.

Write the exponential equation
A. y = 2.5(2)^x
B. y = 10(1/2)^x
C. y = 2(2.5) ^x
D. y = 1/2(10)^x
Answer:
A. y = 2.5(2)^x
Step-by-step explanation:
Given that when
x = 1, f(x) = 5
x = 2, f(x) = 10
x = 3, f(x) = 20
x = 4, f(x) = 40
x = 5, f(x) = 80
x = 6, f(x) = 160
Considering all the options
y = 2.5(2)^x
Substitute x = 1
y = 2.5(2)^1 = 2.5 *2 = 5
Substitute x = 2
y = 2.5(2)^2 = 2.5 * 4 = 10
Substitute x = 3
y = 2.5(2)^3 = 2.5 * 8 = 20
Substitute x = 6
y = 2.5 (2)^6
= 2.5 * 64
= 160
Since the function is true for all the values of x substituted, then the answer is A. y = 2.5(2)^x

O Dela will use 5 teaspoons of vinegar and 26 teaspoons of olive oil to make 4 containers of salad dressing
O Dela will use 6 teaspoons of vinegar and 26 teaspoons of olive oil to make 4 containers of salad dressing
At Dela's Dell, Dela fills containers with homemade vinaigrette salad dressing. The correct option is: O Dela will use 8 teaspoons of vinegar and 26 teaspoons of olive oil to make 4 containers of salad dressing.
To find out how much vinegar and olive oil will be used to make 4 containers of salad dressing, we need to calculate the total amount of vinegar and olive oil used per container and then multiply it by the number of containers.
From the table, we can see that for each container, 2 teaspoons of vinegar and 6.5 teaspoons of olive oil are used.
To find the total amount of vinegar and olive oil for 4 containers, we multiply these amounts by 4:
Vinegar: 2 teaspoons/container * 4 containers = 8 teaspoons
Olive Oil: 6.5 teaspoons/container * 4 containers = 26 teaspoons
Dela will use 8 teaspoons of vinegar and 26 teaspoons of olive oil to make 4 containers of salad dressing.
The correct option is: O Dela will use 8 teaspoons of vinegar and 26 teaspoons of olive oil to make 4 containers of salad dressing.

In the year 2003, a person bought a new car for $18500. For each consecutive year after that, the value of the car depreciated by 12%. How much would the car be worth in the year 2005, to the nearest hundred dollars?
Answer:
Step-by-step explanation:
t is the number of years since 2003.
f(t) = $18,500×0.88^t
t = 2 in 2005
f(2) = $18,500×0.88²≅ $14,300
Answer:
$14300.00
Step-by-step explanation:
100 - 12 = 88%
88% = 0.88
$18500 x 0.88² = $14326.40
To the nearest hundread:
$14326.40 = $14300.00
0.88² means to the power of 2 since it is 2 consecutive years I did to the power of 2. If it was 3 consecutive years then you do 0.88³.

A company sells meal kits. Suppose that 70% of the first-time customers who order a vegetarian meal will order
again, while 65% of the first-time customers who order a gluten-free meal will order again. The company takes
separate random samples of 50 first-time customers who order each kind of meal. The company will then look at
the difference (vegetarian – gluten free) between the proportions of customers who order again in each
sample.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
Answer: A
Approximately normal, because we expect 35 successes and 15 failures from vegetarian orders, and 32.5 and 17.5 from gluten-free orders, and all of these counts are at least 10
Step-by-step explanation: Khan Answer
For vegetarian orders 70% order again, so with a sample size of 50 we will have an estimated 35 people order again: [tex].7*50=35,50-35=15[/tex] This results in 35 successes and 15 failures. For gluten-free orders 65% order again, so with a sample size of 50 we will have an estimated 32.5 people order again:[tex].65*50=32.5,50-32.5=17.5[/tex] This results in 32.5 successes and 15 failures. Because these are all greater than 10, we can assume normality.
Answer:
Approximately normal, because we expect 35 successes and 15 failures from vegetarian orders, and 32.5 and 17.5 from gluten-free orders, and all of these counts are at least 10

Rearrange the equation so uuu is the independent variable.
-12u+13=8w-3
Answer:
u = 8w-16 /-12 or = - 8w-16/12 both mean the same due to the a/-b- = -a/b rule. Then you can factor out the rest. note the fnew subtraction changes mean the same as - (a/b) and should show without brackets as a centre pointing whole fraction subtraction sign.
Step-by-step explanation:
-12u -13 = 8w-3
-12u+13 -13 = 8w-3-13 Eliminate -13 by +13 both sides
-12u = 8w-16 So you are left with one value left side.
-12u/-12 = 8/-12 - 16/-12 Then divide all values by -12 to find value for u and keep the subtraction as 8 never had subtraction sign and no multiplication .
u = 8w-16 /-12 Then you can factor out the rest
This has made u the independent variable then you have a choice to continue showing or ignore u; as u =
= - 8(w-2)/12 Step 1 Factor with subtraction change from -12 to - central fraction
= - 2(w-2)/3 Step 2 Simplify with new minus sign for central fraction to replace a/-b
Answer:
The answer is W = -3/2u + 2

An angle equal to its supplement is _____ degree.
Answer:
90 Degrees.
The angle which is equal to its supplement is 90 degrees.
Answer:
90
Step-by-step explanation:
Let the required angle be x°
Therefore, it's supplement = (180-x)°
Now, x = 180-x
= x+x = 180
= 2x = 180°
Therefore x\ =\ \frac{180°}{2}\ =\ 90°x = 2180° = 90°

Step-by-step explanation:
Let the amount of students = s
Let the amount of adults = a
Three times the adults: 3a
150 fewer than three times the adults:3a-150
amount of students = 150 fewer than three times the adults: s=3a-150
We also know that a+s=1778. Let's sub in the value for s that we got above:
a+s=1778
a+3a-150=1778
4a=1928
a=482
a+s=1778
482+s=1778

Select the two figures that are similar to each other.
A pool measuring 12 meters by 26 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 576 square meters, what is the width of the path?
The width of the path is __?__ meters
Answer:
path width = 3 m
Step-by-step explanation:
let x = the width of the path
(12 + 2x)(26 + 2x) = 576
312 + 24x + 52x + 4x² = 576
4x² + 76x - 264 = 0
divide both sides of the equation by 4:
x² + 19x - 66 = 0
(x + 22)(x - 3)= 0
x = 3 m
