The weight of the guinea pig measured in kilograms is A = 1.130 kg
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the measurement of unit be represented as A
Now , the weight of the guinea pig = 1,130 grams
where from the unit conversion
1000 grams = 1 kg
So , weight of the guinea pig measured in kilograms A = 1,130 grams / 1000
On simplifying , we get
The weight of the guinea pig measured in kilograms A = 1.130 kilograms
Therefore , the value of A is 1.13 kg
Hence , the measurement is A = 1.13 kg

The guinea pig weight measured in kilograms is 1.13kgs.
To convert the weight of a guinea pig from grams to kilograms, you need to understand the relationship between these units:
In the metric system, 1 kilogram (kg) is equal to 1,000 grams (g).
Start with the weight of the guinea pig: 1,130 grams.
Use the conversion factor: 1,000 grams = 1 kilogram.
Divide the weight in grams by the conversion factor to find the weight in kilograms.
1,130 grams ÷ 1,000 = 1.13 kilograms.

Find the equation of the line that has the given properties.
Contains (-4,-2); parallel to the line y = – 5x + 3
The equation of the parallel line is .
(Type your answer in slope-intercept form.)
Answer: y = -5x - 22
Step-by-step explanation:
Use the Point-Slope formula: y - y₁ = m(x - x₁)
m = -5 (parallel means it has the same slope)(x₁, y₁) = (-4, -2)y - (-2) = -5(x - (-4))
y + 2 = -5(x + 4)
y + 2 = -5x - 20
y = -5x - 22

The point marked by the blue arrow is clearly an outlier. I ignored it in "eyeballing" the best-fit line.
My line has four points above and five points below the line,
You probably had to use a statistical calculator to get the equation for the line of best fit.
Assume it was
y = 38.9016 - 0.7951x
You would use that equation to predict y when x = 32.2.
y = 38.9016 - 0.7951 × 32.2 = 39.1588 - 25.6022 = 13.299
If a movie brought in $32.2 million on opening night in Tallahassee, it should bring in $13.299 million in Gainesville.
The expected revenue be for Gainesville is $13.299 million.
Calculation of the expected value:here we assume that
y = 38.9016 - 0.7951x
Here that equation to predict y
when x = 32.2.
So,
y = 38.9016 - 0.7951 × 32.2
= 39.1588 - 25.6022
= 13.299
hence, The expected revenue be for Gainesville is $13.299 million.

Kerry bought a conical tent to put on the back porch. The tent instructions reveal the height at the tallest point to be
4.5 feet and the space inside to be 10.5 cubic feet. About how many square feet of the back porch will be covered by
the tent?
Which measure of the cone needs to be calculated to answer the problem?
A. diameter
B. Radius
C. Base area
D. Volume
Which equation represents the scenario?
A. V= (1/3)(10.5)(4.5)
B. 4.5 = (1/3)(10.5)(h)
C. 10.5 = (1/3)(4.5)(h)
D. 10.5= (1/3)B (4.5)
How many square feet of the back porch will the tent cover?
A. 2.33 square feet
B. 6 square feet
C. 7 square feet
D. 15.75 square feet
1) The measure needed is the C. Base area, 2) the scenario represents the equation D. 10.5= (1/3)B (4.5)
and 3) the tent will cover C. 7 square feet of the back porch.
Use the appropriate formulas to solve it step-by-step.
We know the height (h) of the conical tent is 4.5 feet.The volume (V) of the tent is given as 10.5 cubic feet.The formula for the volume of a cone is:
[tex]V = \frac{1}{3} \pi r^2 h[/tex]
We need to find the base area of the cone (which is a circle) to determine the area covered by the tent on the back porch. The base area (A) of the cone is:
[tex]A = \pi r^2[/tex]
To calculate this, we must first determine the radius (r) of the cone. Let's rearrange the volume formula to solve for the radius (r):
[tex]10.5 = \frac{1}{3} \pi r^2 4.5[/tex]
Simplifying this equation, we get:
[tex]10.5 = \frac{1}{3} \pi r^2 4.5[/tex]
Multiply both sides by 3 to get rid of the fraction:
[tex]31.5 = \pi r^2 4.5[/tex]
Divide both sides by 4.5:
[tex]\frac{31.5}{4.5} = \pi r^2[/tex]
[tex]7 = \pi r^2[/tex]
Divide both sides by π:
[tex]r^2 = \frac{7}{\pi}[/tex]
Taking the square root of both sides, we find the radius (r):
[tex]r = \sqrt{\frac{7}{\pi}}[/tex]
Now we can calculate the base area (A) of the cone:
[tex]A = \pi r^2[/tex]
Substitute r^2 back into the equation:
[tex]A = \pi \left( \frac{7}{\pi} \right) = 7 \text{ square feet}[/tex]

47% of U.S. adults have very little confidence in newspapers. You randomly select 10 U.S. adults. Find the probability that the number of U.S. adults who have very little confidence in newspapers is (a) exactly five, (b) at least six, and (c) less than four
Answer:
[tex]a. \ P(X=5)=0.2417\\\\b. \ P(X\geq 6)=0.3056\\\\c. \ P(X<3)=0.2255[/tex]
Step-by-step explanation:
a. This is a binomial probability distribution problem expressed as:
[tex]P(X=x)={n\choose x}p^x(1-p)^{n-x}[/tex]
Where:
[tex]p[/tex] is the probability a successful event.[tex]x[/tex] the number of successful events.[tex]n[/tex] is the total number of events.Given n=10, p=0.47 the probability of exactly 5 is calculated as:
[tex]P(X=5)={n\choose x}p^x(1-p)^{n-x}\\\\={10\choose 5}0.47^5(1-0.47)^5\\\\=0.2417[/tex]
Hence, the probability that exactly 5 adults have very little confidence is 0.2417
b. Given n=10, p=0.47,
-We substitute our values in formula and the probability of at least 6 is calculated as:
[tex]P(X\geq 6)={n\choose x}p^x(1-p)^{n-x}\\\\\\\ \ \ \ \ \ ={10\choose 6}0.47^6(0.53)^4+{10\choose 7}0.47^7(0.53)^3+{10\choose 8}0.47^8(0.53)^2+{10\choose 9}0.47^9(0.53)^1+{10\choose 10}0.47^{10}(0.53)^0\\\\\\=0.1786+0.0905+0.0301+0.0059+0.0005\\\\\\=0.3056[/tex]
Hence, the probability of at least 6 adults is 0.3056
c. The probability of of less that four adults is calculated as:
[tex]P(X<4)={n\choose x}p^x(1-p)^{n-x}\\\\\\\ \ \ \ \ \ ={10\choose 0}0.47^0(0.53)^{10}+{10\choose 1}0.47^1(0.53)^9+{10\choose 2}0.47^2(0.53)^8+{10\choose 3}0.47^3(0.53)^7\\\\\\=0.0017+0.0155+0.0619+0.1464\\\\\\=0.2255[/tex]
Hence, the probability that less that 4 adults have confidence in the newspapers is 0.2255
The correct probabilities for the given scenarios are:
(a) The probability that exactly five U.S. adults have very little confidence in newspapers is approximately 0.205 or 20.5%. (b) The probability that at least six U.S. adults have very little confidence in newspapers is approximately 0.254 or 25.4%. (c) The probability that less than four U.S. adults have very little confidence in newspapers is approximately 0.347 or 34.7%.
To solve this problem, we can use the binomial probability formula:
[tex]\[ P(X = k) = \binom{n}{k} p^k (1-p)^{n-k} \][/tex]
(a) For exactly five adults:
[tex]\[ P(X = 5) = \binom{10}{5} (0.47)^5 (0.53)^5 \][/tex]
[tex]\[ P(X = 5) \approx 0.205 \][/tex]
(b) For at least six adults, we sum the probabilities of having six, seven, eight, nine, and ten adults with very little confidence:
[tex]\[ P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) \][/tex]
[tex]\[ P(X \geq 6) \approx 0.254 \][/tex]
(c) For less than four adults, we sum the probabilities of having zero, one, two, and three adults with very little confidence:
[tex]\[ P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) \][/tex]
[tex]\[ P(X < 4) \approx 0.347 \][/tex]

What is 5 log 3 + log 4 written as a single logarithm?
A bag contains white marbles and red marbles, 90 in total. The number of white marbles is 6 less than 5 times the number of red marbles. How many white marbles are there?
Answer:
W = 72
Step by step explanation:
White = W
Red = R
W + R = 90
Write an equation
W = 5R - 6
Substitute
5R - 6 = 90
Add 6 to both sides of the equation
5R = 90
Simplify
90 ÷ 5 = 18
R = 18
90 - 18 = W
W = 72
Hope this was useful to you!
Final answer:
By setting up an algebraic equation, we determine that there are 74 white marbles in the bag when the total number of marbles is 90 and the white marbles count is 5 times the number of red marbles minus 6.
Explanation:
Calculating the Number of Marbles
To figure out how many white marbles are in the bag, we can set up a simple algebraic equation. Let's define the number of red marbles as x. According to the problem, the number of white marbles is 5 times the number of red marbles minus 6. We can represent this as 5x - 6. Since we know the total number of marbles is 90, we can write the equation as:
x + (5x - 6) = 90.
Combining like terms results in:
6x - 6 = 90.
Adding 6 to both sides gives us:
6x = 96.
Dividing both sides by 6, we get:
x = 16.
So, there are 16 red marbles. Now, to find the number of white marbles, we plug this back into the equation for white marbles:
5(16) - 6 = 80 - 6 = 74.
There are thus 74 white marbles in the bag.

Step-by-step explanation:
Since there is 10.5 Gallons in 3 minutes, do
10.5/3 = 3.5
(please mark brainliest if this helps!)
Final answer:
The flow rate from the faucet is 3.5 gallons per minute. To determine the amount of water that comes out in any number of minutes, we multiply the flow rate by the number of minutes desired.
Explanation:
Given that 10.5 gallons of water are dispensed in three minutes, we can calculate the rate of flow, which will allow us to determine how many gallons of water would come out of the faucet in any other number of minutes.
We start by finding the flow rate per minute by simply dividing the volume of water dispensed by the number of minutes it took. So, the flow rate is 10.5 gallons / 3 minutes = 3.5 gallons per minute. Now, to find out how many gallons flow in any number of minutes, we multiply the flow rate (3.5 gallons per minute) by the number of minutes.
For example, if we want to know how much water comes out in 5 minutes, we calculate it as follows: Flow rate x Time = 3.5 gallons/minute x 5 minutes = 17.5 gallons. Therefore, 17.5 gallons of water would come out of the faucet in 5 minutes.
Nick is practicing kicking field goals. His first kick is modeled by the parabola that passes through (0,0), (1,6.86), and (2,3) where x is the number of seconds that the ball is in the air, and y is the height of the ball in yards.
Answer:
6.3 yards high
Step-by-step explanation:
The three given points are (0,0), (1,6.86), and (2,3). Use these values in f(x) = ax2 + bx + c.
For (0,0), 0 = 0 + 0 + c.
So, c = 0.
For (1,6.86), 6.86 = a + b + c. Since c = 0:
a + b = 6.86(equation 1)
For (2,3), 3 = 4a + 2b + c. Since c = 0:
4a + 2b = 3(equation 2)
Multiply equation 1 by 2, and subtract the result from equation 2:
2a + 2b = 13.72
4a + 2b - (2a + 2b) = 3 - 13.72
2a = -10.72
a = - 5.36
Plug this value into equation 1:
-5.36 + b = 6.86
b = 12.22
So the function is f(x) = -5.36x2 + 12.22x.
When the ball hits the ground, the height is 0, or f(x) = 0:
Use the function to determine the height of the ball, f(x), after x = 1.5 seconds.
f(x) = -5.36x2 + 12.22x
= -5.36(1.5)2 + 12.22(1.5)
= 6.27
0 = -5.36x2 + 12.22x
0 ≈ x − 2.27(Divide both sides by -5.36x.)
x ≈ 2.27 ≈ 2.3
So, the ball will be about 6.3 yards high after 1.5 seconds.
Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.
x+5 x+4
The area of a rectangle is represented by the multiplication of its length and width. For a rectangle with dimensions 'x + 5' and 'x + 4', the area is given by the standard form polynomial ' [tex]x^2 + 9x + 20[/tex]'.
Explanation:The area of a rectangle is calculated by multiplying the length by the width of the rectangle. Here, the length and width of the rectangle are given by the expressions 'x + 5' and 'x + 4'. Therefore, to find the area, you multiply those two expressions together:
(x + 5) * (x + 4)
When you multiply these two expressions, you get:
[tex]x\times x + 4\times x + 5\times x + 5\times 4 = x^2 + 9x + 20[/tex]
This is the polynomial in standard form that represents the area of the rectangle,
