Answer:
y = 45/x
Step-by-step explanation:
Here, we want to write an inverse relationship
for an inverse relationship, the product of both variables will be equal to the constant term
Let us have the constant term as k
Thus, we have it that;
xy = k
9 * 5 = k
k = 45
So the inverse function is;
xy = 45
or y = 45/x
if y is a function of x, we can have it as;
f(x) = 45/x

Based on data taken from airline fares and distances flown, it is determined that the equation of the least-squares regression line is ŷ = 102.50 + 0.65x, where ŷ is the predicted fare and x is the distance, in miles. One of the flights was 500 miles and its residual was 115.00.
What was the fare for this flight?
102.50
312.50
427.50
542.50
Answer:
542.50
Step-by-step explanation:
Given:
Least square regression equation :
y = 102.50 + 0.65x + residual
y = predicted fare
x = distance in miles
Intercept = 102.50
Slope = 0.65
Distance in miles, x = 500 miles
y = 102.50 + 0.65(500) + 115
y = 102.50 + 325 + 115
y = 427.5 + 115
y = 542.50
Answer:
Don't know why everyone downvoted the first answer. Maybe you guys suck at clicking. It's correct.
Your answer is 542.50 (D)
102.50 + 65(500) = 427.5
427.5 + 115 = 542.50
You add the residue.

Elapsed time 2 hr 37 min, end time: 1:15. start time?
Answer:
10:38
Step-by-step explanation:
2 hours back from 1:15
11:15
37 minutes back from 11:15
10:38
The start time is 10:38.
Answer:
10:38 am
Step-by-step explanation:
You can use a number line or clock to find the start time
x = 0:15 min - 0:37 min x = -0:22 min
y = 60 min - 22 min y = 38 min
Time = 12:38
1st, subtract the minutes from the end time. If the value is negative, it means that the time goes back into the previous hour.
Subtract from 60 minutes. Time after going back 37 minutes.
Next, subtract the hours from the time. 11:38 am 10:38 am and 10:38
Next, subtract the hours from the time. Going back 1 hour. Going back 2 hour.
Start time is 10:38

Answer:
28 degrees
Step-by-step explanation:
147 - 119 = 28
Answer:
Step-by-step explanation:
Since we already know that PQR is 147 degrees, we just need to subtract PQR to QR, and you will get, (147 - 119), PQ as 28 degrees!
57 divided by 592,346
Answer:
9.62 x 10⁻⁵
Step-by-step explanation:
57 / 592346 = 0.0000962275
Scientific notation: We moved the decimal 5 times to the right, and in order to put the number back in standard form, we have to move the decimal 5 times to the left. So the scientific way of saying this is 9.62 x 10⁻⁵
9.62 x 10⁻⁵ or 57 / 592346 = 0.0000962275

Pasta Place needs to make pasta with garlic cream sauce for 80 guests at a party. One batch of pasta calls for 3 cups of cream and feeds 10 people. The restaurant already has 5 pints of cream in the fridge. How many more pints of cream will they need for the pasta?
Answer:
Total pints of cream will they need for the pasta = 7 pints
Step-by-step explanation:
Given - Pasta Place needs to make pasta with garlic cream sauce for 80 guests at a party. One batch of pasta calls for 3 cups of cream and feeds 10 people. The restaurant already has 5 pints of cream in the fridge.
To find - How many more pints of cream will they need for the pasta?
Solution -
10 people = 3 cups of cream
⇒80 people = 8×3 = 24 cups of cream
Now,
We know that,
1 cup = 0.5 pints
⇒24 cup = 24×0.5 = 12 pints.
Now,
Given that, The restaurant already has 5 pints of cream in the fridge.
So,
Total pints more needed = 12 - 5 = 7 pints.
∴ we get
Total pints of cream will they need for the pasta = 7 pints

What is the range of 39,41,5,43,26,7,43,24,41
Answer:
38
Step-by-step explanation:
The range of a data set is the smallest number subtracted from the largest number.
[tex]39,41,5,43,26,7,43,24,41[/tex]
In this data set, the largest number is 43 and the smallest number is 5.
[tex]43-5=38[/tex]
Therefore, 38 is the range of this data set.
What additional information is needed to show that ABC = DEF by SSS?
Answer:
D.) AC ≈ DF
Step-by-step explanation:
The SSS (Side-Side-Side) congruence postulate states that 2 triangles will be congruent assuming that all 3 of their sides are congruent.
In this case, we know that:
AB ≈ DECB ≈ FESo, that's two pairs of congruent sides. We need one more pair of congruent sides to prove SSS congruence. The last two remaining are sides CA and FD!

Please find x and y!!!!!! URGENT! Bots taken down
Answer:
x = 11, y = 22
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{11\sqrt{3} }{x}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by x )
11[tex]\sqrt{3}[/tex] = x × [tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
11 = x
Using Pythagoras' identity in the right triangle
y² = x² + (11[tex]\sqrt{3}[/tex] )² = 11² + 363 = 121 + 363 = 484 ( square root of both sides )
y = [tex]\sqrt{484}[/tex] = 22
