Answer:
y = 0.714 x -5
Step-by-step explanation:
at x =0, y = -5, means the constant is -5
at x= -7 y= -8,
-8= -7a -5
a=0.714
y = 0.714 x -5

If $1=Rs. 102.50 and £ 1=Rs, 140, how many dollars equals to £5?
Answer:
$6.83= £5
Step-by-step explanation:
As £ 1=Rs 140
So, £5 = Rs 140 x 5
£5 = Rs 700 ...(i)
Now, Rs. 102.50 = $ 1
So, Rs. 1 = $ (1/102.5)
Therefore, Rs. 700 = $ (1/102.5)x 700 = $6.83
By using equation (i)
£5 = $6.83
Hence, there are $6.83= £5

For the month of march, Kasey plans to vacuum her floor every fourth day and clean her bathroom every seventh day if she begins this march 1, on what day of the month will she do both jobs?
Answer: March 28
Step-by-step explanation:
Solve for this by checking for the lowest common multiple of 7 and 4.
Multiples of 7: 7, 14, 21, 28, 35
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32
Lowest is 28 so on March 28th she both will vacuum her floor and clean her bathroom.
-7.5x + 0.25 = -5.75
The value of x is =
Answer:
x = 4/5
I hope this helps!
Answer:
x = .8
Step-by-step explanation:
-7.5x = -5.75 - 0.25
-7.5x = -6.0
-6.0/-7.5 = .8
Answer the Point-slope equation with line for given point and have the slope given
(4,-3),m=-1
Answer:
y + 3 = - (x - 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 1 and (a, b) = (4, - 3) , then
y - (- 3) = - 1 (x - 4) , that is
y + 3 = - (x - 4)
The graph of a function is shown:
Which of the following correctly identifies the set of outputs?
O {(-3,2), (-2, 1), (3, 3), (3, -1)}
O {(2, -3), (1, -2), (3, 3), (-1,3)}
O {-3, -2,3}
O {-1, 2, 3}
Answer:
C, (-3, -2, 3)
Step-by-step explanation:
I literally just had this question and i got a 100. You just find what the points are, and choose the y-axis point because it's the output, like the x-axis point is the input. So for starters, we can look at the point in the upper right square corner on the grid. You would go to the left 3 times, along the x-axis, and it would be -3. Then you would go up 2 times, along the y-axis, and it would be positive 2. So the plot for that point is (-3, 2) but we want the output which is the y-axis so it would be 2. Do the same with all of the points. [you can already rule out the first 2 choices because that's giving all of the points, not just the outputs] That leaves you with the bottom 2 and only one of the choices has the positive 2 which we already found. Hence, the answer is C. Trust me, it's not hard, i didn't have to read anything, i just figured it out. And if i can, you can. You got this!
An animal park has lions tigers and zebras.20% of the animals are lions and half the animals are zebras.If there are 120 animals at the park , how many tigers are there?
Answer:
40
Step-by-step explanation:
20% of 120 which is 24 are lions
half of the animals which is 120 ÷ 2 is 60 for the zebra
therefore, 60+24 is 84
120 - 84 is 36

The physical education teacher assigns each student a number from 1 to 100 and uses a
computer to randomly generate a list of 30 numbers to select the students for the
sample. What type of sampling is being used?
Answer:
Simple random sampling
Step-by-step explanation:
The type of sampling used here is simple random sampling(SRS) because SRS is defined as the sampling technique where a group of subjects known as sample are selected for study from a larger group known as population. Thereafter, each individual will be entirely chosen by chance and then each member of the population will have an equal opportunity of being included in the sample.
Thus question given corresponds to this definition.

Answer:
y = 25, 17, 13, 5 . . . . (top-down order)
Step-by-step explanation:
Put the values of x in the expression for y and do the arithmetic.
y = 29 - 4×1 = 25
y = 29 - 4×3 = 17
y = 29 - 4×4 = 13
y = 29 - 4×6 = 5
y=-x Identify the slope and y-intercept
Answer:

Step-by-step explanation:
the number with the equation
Answer:
Slope: m = -1 y-intercept: b = 0Step-by-step explanation:
slope-intercept form of equation: y = mx + b
wherae m is the slope and b is the y-intercept
So:
y = -x
y = -1x + 0 ⇒ m = -1 b = 0
What is the value of s ?
Answer:
The value is 17
Step-by-step explanation:
This is because to find the hypotenuse you use the equation [tex]a^{2} + b^{2} =c^{2}[/tex].
So you would square 15 and 8 then add them up to get [tex]c^{2}[/tex]. After this you just need to find the square root of [tex]c^{2}[/tex] to get "c" by itself or in this case "s".
The graph below displays the relative frequency distribution for X, the total number of dogs and cats owned per household, for the households in a large suburban area. For instance, 14 percent of the households own 2 of these pets.
Number of dog/ Relative Frequency

1- 0.24
2- 0.14
3-0.09
4- 0.07
5- 0.04
6-0.04
7- 0.02
(a) According to a local law, each household in this area is prohibited from owning more than 2 of these pets. If a household in this area is selected at
random, what is the probability that the selected household will be in violation of this law? Show your work.
(b) If 12 households in this area are selected at random, what is the probability that exactly 3 of them will be in violation of this law? Show your
work.
(c) The mean and standard deviation of X are 1.65 and 1.851, respectively. Suppose 100 households in this area are to be selected at random and X , the
mean number of dogs and cats per household, is to be computed. Describe the sampling distribution of X , including its shape, center, and spread.

In a new necklace, the ratio of star-shaped beads to moon-shaped beads is 5 to 2. If the necklace has 20 star shaped beads, how many total beads are on the necklace? Explain.
Answer:
28
Step-by-step explanation:
In the ratio:
star-shaped beads = 5
moon-shaped beads = 2
total number of beads = 5 + 2 = 7
ratio of star-shaped beads to total number of beads = 5:7
star-shaped beads = 20
Let x = total number of beads.
20/x = 5/7
Cross multiply.
5x = 20 * 7
Divide both sides by 5.
x = 4 * 7
x = 28

The average human fingernail grows at a rate of 3.47 millimeters per month. One millimeters = 0.1 centimeters. How much in centimeter, would the average human fingernail grown in one year?
Answer:
4.164 cm
Step-by-step explanation:
Given that:
Growth of an average human fingernail = 3.47 mm per month
One mm (millimeter) = 0.1 cm (centimeter)
To find:
Growth of an average human fingernail in one year = ?
Solution:
Here, we are given the growth for one month.
There are 12 months in an year, so growth over an year can be found by adding the growth of one month for 12 times.
Growth in one year = 3.47 mm + 3.47 mm+ ..... 12 times
Growth in one year = 12 \times 3.47 mm = 41.64 mm
In millimeters, the growth of an average human fingernail = 41.64 mm
Let us convert it into centimeters by multiplying it with 0.1.
Therefore growth in centimeters = 41.64 mm [tex]\times[/tex] 0.1 = 4.164 cm
How do you write a slope parallel to a line?
Answer:
slope is m. Parallel means it has the same slope as the line it's parallel to. Let's say the slope of line 1 is 3, and your y intercept is 12. The equation would then be y = 3x + b and b would be 12 bc x would be 0 at y intercept making the equation become y = (0)x+b and for y to be 12, b has to be 12 in this case. So y = 3x + 12
Alice spent $131 on shoes. Flip flops cost $15 and Sneakers cost $28. If she
bought a total of 7 shoes, then how many of each kind of shoe did she
buy? Write the answer as an ordered pair...(flip flops, sneakers). Do not
include the units. *
Answer:
Flip flops = 5
Sneakers = 2
Step-by-step explanation:
Let
x = flip flops
y = sneakers
x + y = 7 (1)
15x + 28y = 131 (2)
From (1)
x = 7 -y
Substitute x = 7 - y into (2)
15x + 28y = 131
15(7 - y) + 28y = 131
105 - 15y + 28y = 131
-15y + 28y = 131 - 105
13y = 26
y = 26/13
= 2
y = 2
Substitute y = 2 into (1)
x + y = 7
x + 2 = 7
x = 7 - 2
= 5
x = 5
Flip flops = 5
Sneakers = 2
