what are you asking?
Step-by-step explanation:
For part of the first year of a dog's life, its growth can be
approximated using a linear function. Emilie has two puppies:
a Border collie and a younger Saint
Bernard. During a 4-week period,
the Border collie grows from
13.4 kg to 17 kg, while the Saint
Bernard
grows from 6 kg to 12.4 kg.
Suppose each dog grows at a
constant rate. Will the dogs
ever have the same mass? If
so, approximately what is
the mass?
A bag contains 3 red marbles, 4 blue marbles and 8 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be blue?
Answer:
Brainleist!!!!!
Step-by-step explanation:
there are 15 marbles
4 are blue
4/15 chance of geting one blue
3 marbles for getting on blue would be 16/225
16/225 = 0.07111111111111111111111111111111
rounded-16/225 = 0.7
The probability that the all three marbles drawn will be blue is given by the relation P ( B ) = 0.85 %
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
The total number of marbles in the bag is 3 + 4 + 8 = 15.
We want to find the probability of drawing all three blue marbles, which is a combination probability problem without replacement.
The probability of drawing the first blue marble is 4/15, since there are 4 blue marbles out of 15 total marbles.
After drawing the first blue marble, there are only 3 blue marbles left in the bag out of 14 total marbles (since one marble has already been drawn), so the probability of drawing the second blue marble is 3/14.
Similarly, after drawing the first two blue marbles, there are only 2 blue marbles left in the bag out of 13 total marbles, so the probability of drawing the third blue marble is 2/13.
To find the probability of all three events happening (drawing three blue marbles in a row), we multiply the individual probabilities together:
Probability of drawing all three blue marbles = (4/15) * (3/14) * (2/13)
P ( B ) = 0.85 %
Hence , the probability, to the nearest 10th of a percent, of drawing all three marbles as blue is 0.85%.

3x + 3 = 25 − 3x x = Find a two-decimal-place approximation of each solution. (Enter your answers as a comma-separated list. If there is no solution, enter NO.
The two-decimal-place approximation of the solution to the equation is x ≈ 3.67.
To find the solutions to the equation 3x + 3 = 25 - 3x, we can start by simplifying the equation:
3x + 3x = 25 - 3
6x = 22
x = 22/6
Using a calculator or performing the division, we can find the decimal approximation of x:
x ≈ 3.67
Therefore, the two-decimal-place approximation of the solution to the equation is x ≈ 3.67.
we want to isolate the variable x on one side of the equation. We can do this by combining like terms and performing algebraic operations to simplify the equation.
By adding 3x to both sides of the equation, we eliminate the variable on the right side, and by subtracting 3 from both sides, we isolate the variable on the left side. This leads us to the equation 6x = 22.
To find the value of x, we divide both sides of the equation by 6, which gives us x = 22/6. This is the exact solution of the equation.
However, since the question asks for two-decimal-place approximation, we can use a calculator or perform the division to find x ≈ 3.67.

Consecutive even integer word problem help please!!
Answer:
Width: 16 in., Length: 18 in.
Step-by-step explanation:
Consecute even/odd problems seem a bit weird at first.
You choose a variable to represent the first integer, say n . Assume it's even (no symbolic way to tell!). If n is even, then the next consecutive integer is n + 2. You add two because you want to skip one integer.
Width: n
Length: n + 2
Area is length multiplied by width, so
\(n(n+2)=224\\\\n^2+2n=224\\\\n^2+2n-224=0\\\\(n+14)(n-16)=0\\\\n+14=0 \text{ or } n-16=0\\\\n=-14 \text{ or }n=16\)
The negative solution makes no sense, so use n = 16

At what point on the curve y = 9 + 2ex − 5x is the tangent line parallel to the line 5x − y = 8?
(x, y) = ?
Answer:
\((\ln(5), 19-5\ln(5))\)
Step-by-step explanation:
The line can be represented as y=5x-8, so the slope of the line is 5.
The derivative of the curve is:
\(\frac{d}{dx} [9+2e^x-5x]\\=\frac{d}{dx} [9]+\frac{d}{dx} [2e^x]-\frac{d}{dx} [5x]\\=2e^x-5\\\)
We need to set that equal to 5 to find the x coordinate of our desired point
\(2e^x-5=5\\2e^x=10\\e^x=5\\x=\ln(5)\)
Now, just plug in x in the curve to solve for y:
\(9+2e^{\ln(5) } -5\ln(5) = y\\9+10-5\ln(5)=y\\19-5\ln(5)=y\)
Line 5x y = 8 has a slope of 5. This means that the tangent line that runs parallel to this line must also have a slope of 5.
To solve this equation
dy/dx = 2ex 5 is the derivative of the function y = 9 + 2ex 5x. Consequently, 2ex 5 is equal to the slope of the tangent line at any location.
When we set the slope of the tangent line to 5, we obtain:
2ex − 5 = 5
2ex = 10
e^x = 5
Taking the natural logarithm of both sides, we get:
ln(e^x) = ln(5)
x = ln(5)
Therefore, ln(5) is the x-coordinate of the crossing point.
We can enter this value of x into the original function to determine the y-coordinate:
y = 9 + 2e^(ln(5)) − 5(ln(5))
y = 9 + 10 − 5ln(5)
y = 15 − 5ln(5)
As a result, the intersection is at (ln(5), 15 5ln(5)).
To sum up, (ln(5), 15 5ln(5)) is the point on the curve y = 9 + 2ex 5x where the tangent line is parallel to the line 5x y = 8.

the riverton branch of the national bank of wyoming has 10 real estate loans over $1,000,000. of these 10 loans, three are "underwater." a loan is underwater if the amount of the loan is greater than the value of the property. the chief loan officer decided to randomly select two of these loans to determine if they met all banking standards. what is the probability that neither of the selected loans is underwater? (round your answer to 4 decimal places.)
The probability that neither of the selected loans is underwater is approximately 0.5444.
To find the probability that neither of the selected loans is underwater, we need to calculate the probability of selecting a loan that is not underwater for both selections.
Out of the 10 real estate loans, 3 are underwater. So, the probability of selecting a loan that is not underwater for the first selection is (10 - 3) / 10 = 7/10.
After the first selection, there are 9 loans left, out of which 2 are underwater. So, the probability of selecting a loan that is not underwater for the second selection is (9 - 2) / 9 = 7/9.
To find the probability of both events happening, we multiply the probabilities together:
Probability = (7/10) * (7/9) = 49/90 ≈ 0.5444
Therefore, the probability that neither of the selected loans is underwater is approximately 0.5444.

if a qantas 787-9 with 285 passengers and 14 crew flew 7,536 miles from los angeles, california to sydney australia, how many revenue passenger miles (rpm) were flown on this flight?
The number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.
Revenue Passenger Miles (RPM) is a measure of how much passenger traffic an airline is serving, and is calculated by multiplying the number of revenue passengers (passengers paying a fare) by the distance travelled in miles. For this flight, the number of RPM is calculated as follows:
RPM = (Number of Revenue Passengers) x (Distance Travelled in Miles)
RPM = (285 Passengers) x (7,536 Miles)
RPM = 2,150,960 Miles
Therefore, the number of RPM flown on this flight from Los Angeles to Sydney is 2,150,960 Miles.

Step-by-step explanation:
13.8 times 68.also what is overtime pay that no answer
Answer: $20.7 per hour of overtime
$1131.6 gross pay for the week
Step-by-step explanation: traditional overtime pay is 1.5 times regular pay meaning that she earns 13.8•1.5 for her overtime
multiply 13.8 times her regular 40 hour work week plus 28 hours of overtime pay
(13.8•40)+(13.8•1.5)•(hours of overtime)=gross pay
this is all subjective depending on your states overtime laws and if they count overtime as double for hours worked in excess of 48 hours in a week.
I would look at your states overtime laws and work on a conclusion.
if this is the case then the answer would be
(13.8•40)+(20.7•8)+(27.6•20)=gross pay

Which value of x makes the expression above equivalent to 14 Square root 7?
Pls helppppppppppppppp
Answer:
B. 4
Step-by-step explanation:
First, let's evaluate the first expression:\(7 \sqrt{7x} = \sqrt{49 \times 7x} \)
We can just remove the √ from both sides to make it easier to see, so49 × 7x = 343x
Now, let's evaluate the second expression:14√7 = √(1372)
To see what value would make the first expression equal to the second expression, we can divide the the second expression by first expression:1372 ÷ 343 = 4 this is the vaule of x.
