Answer:
y-intercpet is In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
15 men can dig a ditch in 10 days, how many day
Will 10men take working at the same rate
Answer:
If 10 men dig a ditch in 12 days .
Total man-days required to dig the ditch
= 10 men × 12 days
= 120 man-days
how long would 15 men take to dig it?
No of days required to finish the job by 15 men
= 120 men-days / 15 men
= 8 days
Answer: 8 days will be required to finish the job by 15 men

What is the slope of a line perpendicular to the line whose equation is
2x – 2y = 20.
Answer:
-1
Step-by-step explanation:
Solve for y into y=mx+b
2x-2y=20
-2y=-2x+20
y=(-2x+20)/-2
y=x-10
the slope is m, so it’s 1
A line perpendicular to that would be -1

Write the multiple regression equation for miles per gallon as the response variable. Use weight and horsepower as predictor variables. See Step 5 in the Python script. How might the car rental company use this model
Answer:
Step-by-step explanation:
Response Variable: Miles per gallon
Predictor Variables: Weight, Horsepower
The multiple regression equation would be: M = aW + bH + c
where M = miles per gallon
a = slope of the graph of W on M OR rate of change in M due to change in W
W = weight
b = slope of the graph of H on M OR rate of change in M due to change in H
H = horsepower
c = intercept of M on the y-axis OR constant variable
How might the car rental company use this model?
The car rental company might use the regression model to determine the following:
- Effect of weight (of car) on miles run per gallon (of premium motor spirit)
- Effect of horsepower on miles per gallon; etc.
What are the domain and range of the function?

Answer:
Assuming that the question is
[tex]f(x)=\frac{3}{5x^5}[/tex]
The asnwer would be
Domain: (- ∞,0) U (0, ∞)
Range: ( - ∞,0) U (0, ∞)
Step-by-step explanation:
The domain and range of the function are:
Domain: (- ∞,0) U (0, ∞)

Domain and Range of function
The domain are the input values for which a function exist while the range are output value for which the function exist.
Given the function:
g(x) = 35x^5
The function can exist on all real values since we will have a correspoding value of y for every value of x.

(__-3)(__+7)=2x^2+x-21
Answer:
(x - 3)(2x + 7) = 2x^2 + x - 21
Step-by-step explanation:
2x^2 + x - 21 = (__ - 3)(__ + 7)
The first term of the trinomial is 2x^2 which can be factored into 2x * 2.
You need to place 2x in one blank and x in the other blank.
Try it both ways. Then multiply the factors out to see which one gives you the correct middle term.
Try 2x - 3.
(2x - 3)(x + 7) = 2x^2 + 14x - 3x - 21 = 2x^2 + 11x - 21
This gives the middle term 11x, but we need the middle term to be x, so now we try x - 3.
(x - 3)(2x + 7) = 2x^2 + 7x - 6x - 21 = 2x^2 + x - 21
This gives the correct middle term, x, so this is the correct factorization.
Answer:
(x - 3)(2x + 7) = 2x^2 + x - 21

Some please help me
Answer:
48 students
Step-by-step explanation:
Represent algebra with A and physics with P
Given
Total = 50
n(A) = 39
n(P) = 16
n(Both) = 7
Required
Determine students taking Algebra or Physics
This is calculated using
n(A or P) = n(A) + n(P) - n(Both)
n(A or P) = 39 + 16 - 7
n(A or P) = 48
A total of 48 students are enrolled in either physics or algebra.
Number of students taking algebra n(A)= 39
Number of students taking physics n(B)= 16
Number of students taking both subjects n(A∩B)= 7
So, the number of students taking either physics or algebra will be the union of sets i.e. n(A∪B)
What does the union of sets represent?The union of two sets is a set containing all elements that are in A or in B (possibly both).
As we know,
n(A∪B) = n(A) + n(B) - n(A∩B)
n(A∪B) = 39+16-7
n(A∪B) = 48
Therefore, A total of 48 students are enrolled in either physics or algebra.

Rick has 10 more crayons than Lori. Lori has 136 crayons. Tom has 10 fewer crayons than Rick. How many crayons does each child have?
Step-by-step explanation: Uh if Lori has 136 crayons. And rick has 10 more than her He would have 146 And tom has 10 fewer crayons than rick so he would have 136
Lori:136
Rick:146
Tom:136
And idk if u need this or not but if u want it all together it would be: 418
Hope this helps!)
Rick has 146 crayons, Lori has 136 crayons and Tom has 136 crayons'
Let the number of crayons Rick have be x
Let the number of crayons Lori has be y
Let the number of crayons tom has be z
If Rick has 10 more crayons than Lori, then;
x = 10 + y
Since Lori has 136 crayons, hence y = 136
x = 10 + 136
x = 146
If Tom has 10 fewer crayons than Rick, then;
z = x - 10
z = 146 - 10
z = 136
Hence rick has 146 crayons, Lori has 136 crayons and Tom has 136 crayons'

If adult females are randomly selected, find the probability that they have pulse rates with a mean between 70beats per minute and 82beats per minute.
This question is incomplete.
Complete Question
Assume that females have pulse rates that are normally distributed with a mean of u = 76.0 beats per minute and a standard deviation of 12.5 beats per minute. If 1 adult female is randomly selected, find the probability that her pulse rate is between 70 beats per minute and 82 beats per minute. The probability is (Round to four decimal places as needed.)
Answer:
0.3688
Step-by-step explanation:
The formula for calculating a z-score when given a random sample of numbers is is z = (x-μ)/σ/√n
where x is the raw score,
μ is the population mean, and
σ is the population standard deviation.
mean = 76.0 beats per minute and a standard deviation = 12.5 beats per minute.
n = number of random samples = 1
For 70 beats per minute
z = 70 - 76/12.5/√1
z = -0.48
Probability value from Z-Table:
P(x = 70) = 0.31561
For 82 beats per minute.
z = 82 - 76/12.5/√1
z = 0.48
Probability value from Z-Table:
P(x = 82) = 0.68439
The probability that her pulse rate is between 70 beats per minute and 82 beats per minute.
P(x = 82) - P(x = 70)
0.68439 - 0.31561
= 0.36878

A club had some money to purchase new chairs. After buying 355 chairs at $199 each, there was $1,068 remaining. How much money did the club have at first? *
Answer:
$71713
Step-by-step explanation:
If each chair cost $199 then multiple 199 by 355
[tex]199*355= 70645[/tex]
If they still have 1068 then add that into the sum
[tex]70645+1068=71713[/tex]
So your answer is $71713
Answer: $71,713
Step-by-step explanation:
First you would multiply 355 by 199 to get 70,645. Next you would add the remainder of what they had, $1,068, and get the answer. hope this helps.
