Answer:
You can find and write the equations in Slope-Intercept form due to the slope and y-intercept.
Step-by-step explanation:
The Slope-Intercept Form Formula: y=mx+b
The m represents the slope while the b represents the y-intercept
You can also use y2 - y1 / x2 - x1 to find the slope which is the m in your formula.
Lastly, to find a y-intercept, you can plug in your coordinate for the x and y to do two-step linear equations.
A hose fills a hot tub at a rate of 4.39 gallons per minute. How many hours will it take to fill a 350-gallon hot tub?
Answer:
1.33 hours(If it doesn't let you type that in, just do 1 hour for rounding purposes)
Step-by-step explanation:
First, we take the 350 gal variable and divide that by 4.39, we now get 79.73
Now, we convert that into hours(60mins per hour), so 79.73 divided by 60.
We get 1.33, which is your answer!

which matrix is equal to ( -6 -6.5 1.7 2 -8.5 19.3 )
The matrix that is equal to the considered matrix [-6,-6.5,1.7; 2, -8..5, 19.3 ] is given by: Option D: [-6,-6.5,1.7; 2, -8..5, 19.3 ]
When are two matrices called being equal?Two matrices are equal if and only if their shapes are same, and they've got the same elements for each corresponding row and column positions.
The missing options are specified in the image attached below.
The considered matrix is:
[tex]\left[\begin{array}{ccc}-6&-6.5&1.7\\2&-8.5&19.3\end{array}\right][/tex]
It has 2 rows and 3 columns.
Evaluating each of the options:
Option A and B are wrong as they've got 3 rows and 2 columns, which makes their shape not matching with the shape of the considered matrix.
Option C although has got 2 rows and 3 colums, but its elements are not matching with corresponding elements of the considered matrix.
Option D has 2 rows and 3 colums and its each element matches with the corresponding element of the considered matrix. (ie, for example, element common in first row and first column in option D is -6, and so as for the considered matrix, and similarly, all correspoding elements for each row and column is same in both matrices.)
Thus, the matrix that is equal to the considered matrix [-6,-6.5,1.7; 2, -8..5, 19.3 ] is given by: Option D: [-6,-6.5,1.7; 2, -8..5, 19.3 ]

suppose the acceleration function of an object moving along a line is given by a(t) =0.2t. find the position of the object if you know the initial velocity was v(0) =-3 and initial position was s(0) =1
Answer:
See below
Step-by-step explanation:
sf = s0 + v0 t + 1/2 at^2
1 + (-3)t + 1/2 (.2t) t^2 ( weird acceleration value)
s = 1 -3t + .1 t^3 You will need a 't' value to determine the position
What is the value of x?
Answer:
[tex]x = 52[/tex]
Step-by-step explanation:
Step 1: Create an expression
[tex]2x + 76 = 180[/tex]
Step 2: Subtract 76 from both sides
[tex]2x + 76 - 76 = 180 - 76[/tex]
[tex]2x = 104[/tex]
Step 3: Divide both sides by 2
[tex]\frac{2x}{2} = \frac{104}{2}[/tex]
[tex]x = 52[/tex]
Answer: [tex]x = 52[/tex]
Answer:
x = 52
Step-by-step explanation:
the 2 inside angles add up to 180 degress since they lie on the same side on the transversal line. so we set the eqaution up:
2x+76=180
2x=104
x=54

Given two independent events A and B, the probability of both event A and event B occurring is equal to the probability of A plus the probability of B. Please Explain.
Answer:
Step-by-step explanation:
You would add probabilities if you want to find out if one event or another could happen. For example, if you roll a die, and you wanted to know the probability of rolling a 1 or a 6, then you would add the probabilities:
Probability of rolling a 1: 1/6
Probability of rolling a 6: 1/6
So the probability of rolling a 1 or a 6 is 1/6 + 1/6 = 2/6 = 1/3.
2. Calculate the mean of the following
sample:
20, 15, 22, 13, 14, 18, 19, 11, 23, 17
Answer choices:
16.8
17.2
17.6
Answer:
what is mean: mean is the "average" of a set of numbers and it is calculated by adding up the values given and dividing by the total number of values given.
Step-by-step explanation:
formula: addition of all values divided by the number of values given.
total number of values given = 10 ( count each number as one )
so ..
20+15+22+13+14+18+19+11+23+17 = 172
divided by 10
= 17.2 ( decimal)
or 17 whole number 1/5 ( mixed fraction )
or 86/5 ( improper fraction ).
Hope this helps.
Good luck .
in a significance test of one population mean if vairance of population is unknown but the sample size is 30 or more we use z test why?
The student T distribution would be used since we don't know the population variance (by extension the population standard deviation).
However, if n > 30, then the student T distribution is going to look very similar to the standard normal Z distribution. It won't be a perfect match, but it'll be close enough that it's more simple to use the Z distribution. With the Z distribution, you only have one set of values and you don't have to worry about the degrees of freedom.

under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
(3, 4 ) → (3, - 4 )
(3, 1 ) → (3, - 1 )
(5, 1 ) → (5, - 1 )
Answer:
Points would be (3,-1) (5,-1) (3,-4)
Step-by-step explanation:
So its asking for a reflection on the x-axis, which means you simply take the shape and move the points to the same spot on the other side of the boldest horrizontal line, or in other words, you can just add a negative to the y variable in the points, because the rule is (x,-y).

Step-by-step explanation:
Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the y-axis and time on the x-axis. The slope will be 2.2 at every point along her bike ride.
Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5
Answer:
B. Every 5 minutes 11 ft. traveled
2.2ft.= every 1 minute
C. Steeper. this is because her rate of change is much higher than before

On a motor trip, Mr. Williams covered 2/6 of his total trip distance by driving 388 miles. The total distance to be covered in miles
is:
A. 1,438
B. 1,164
C. 1,382
D. 1,218
Answer:
B
Step-by-step explanation:
2/6 x d = 388
d = 388 x 6/2 = 1164 m
Answer:
The total distance covered in miles is B, 1164 miles.
Step-by-step explanation:
Since we know that 2/6 of his total trip distance is 388 miles we can do 388 / 2/6 = 1164. Therefore, his total trip distance is 1164 miles.
