A person can burn
8 Calories per minute of running.
Determine whether the number of
Calories is proportional to the number
of minutes
Answer:
absolutely
Step-by-step explanation:
if you run for one min., you burn 8 calories right?
so if you run for example 10 mins., you would burn 80 calories
80>8
so yes

A researcher wishes to estimate the proportion of all adults who own a cell phone. He takes a random sample of 2000 adults; 1650 of them own a cell phone. The population of interest to the researcher is:______
Answer:
All the adults
Step-by-step explanation:
The question says that the researcher wants to estimate all adults that own a cell phone.
So the population of interest is all the adults.
The statistic is the proportion p^ of the random sample of 2000 adults;
P^ = 1650/2000
= 0.825
The parameter of interest in the question is p, which is the proportion of those adults that own a cell phone.
Help with substitution
Answer:
x=5
y=1
Step-by-step explanation:
First, put x=2y+3 inside 2x, which is the top equation. This will come out as 2(2y+3)-3y=7.
If you distribute, it would become 4y-6-3y=7. Then you have to combine like terms to get y+6=7
Add 6 on both sides to get y=1.
Put the value of y, which is 1 into the top or bottom equation. I would prefer the bottom equation because it is simpler. The equation would come out as
x=2(1)+3
x=2+3
x=5
Answer:
The answer will be listed below.
Step-by-step explanation:
Since there is an x= 2y+3, you can plug that equation into x in the equation 2x-3y=7. You must find y first.
2(2y+3)-3y=7
Now distribute 2 and you will get 4y+6-3y=7.
Combine 4y and -3y and have an equation of y+6=7.
Subtract 6 to both sides and you will have an answer of y=1
Now since you found y, now find x. To find x, substitue y=1 into any equation listed (you'll get the same answer anyways). Let's use x=2y+3 as an example. Substitute the 1 for y.
x=2(1)+3
Now you have x=2+3, which is 5.
x=5 and y=1.
To make sure this is correct, plug both the numbers into an equation, let's use the first one now.
2(5)-3(1)=7
7=7
In the end, the euqtaion equals 7, which means the answer is correct.

W- 33 = 66 what is W
w is equal to 99 cause is u subtract 33 fro it it equals 66
Answer:
W = 99
Step-by-step explanation:
To solve W, you need to isolate W. Add 33 to both sides:
W-33=66
W=99

Remember that whole numbers that are next to each other, for example, 2 and 3, or 43, 44, and 45 are called consecutive numbers.
If n is the larger of two consecutive numbers, write an expression for the other number.
Given:
Whole numbers are next to each other and they are called consecutive numbers.
To find:
The expression for the other number if the larger of two consecutive numbers is n.
Solution:
According to the given definition, whole numbers are next to each other and they are called consecutive numbers. It means the difference between two consecutive interest is 1.
Larger number - Small number = 1
[tex]n-\text{Smaller number}=1[/tex]
Add smaller number on both sides.
[tex]n=1+\text{Smaller number}[/tex]
Subtract 1 from both sides.
[tex]n-1=\text{Smaller number}[/tex]
Therefore, the expression for the other number is n-1.

Height of marble from the ground
Explanation:
Dora wanted to see whether the position of the marble on the ramp (which would be the height) has an effect on the kinetic and potential energy of the marble, then the height would be the independent because it is what is being changed. An independent variable is the variable in an experiment that you change to see if it has an effect on the dependent variable.
The dependent would be the kinetic and potential energy and the constant would be the type of marble.

Find an equation of the tangent line to the of the function at the given point.
f(x) = 3x2 – In x (1,3)
The answer is 5x-y-2=0 but I don’t know how to get to it.
Step-by-step explanation:
The slope of the tangent line is equal to the derivative.
f(x) = 3x² − ln x
f'(x) = 6x − 1/x
f'(1) = 6(1) − 1/1
f'(1) = 5
Use point-slope form:
y − 3 = 5 (x − 1)

Answer:
29
Step-by-step explanation:
5x+35=180 cuz 3x+2x, and 15+20
the subtract 35 on both sides, so 5x = 145
x=29
lets check
3(29)+15 = 102
2(29)+20 = 78
102+78 = 180
so x = 29
Answer:
29
Step-by-step explanation:
3x+15+2x+20=180
Combine like terms
5x+35=180
Subtract 35 on both sides
5x=145
Divide by 5 on both sides
x=29
11. A recipe calls for 1/2
tsp of vanilla extract and
2 1 / 2
cups of sugar. Jack used 10 cups of
sugar for his recipe. How much vanilla extract does he need for the recipe to taste
right?
Answer:
if jack uses 10 cups of sugar he will need to use 6 tsp of vanilla extract
Step-by-step explanation:
10 devided by 2 1/2= 4
and 1/2 multiplied by 4 is 6
Answer:
2 tsp
Step-by-step explanation:
This is a ratio/ proportionality problem. The recipe calls for 2 1/2 cups of sugar, Jack uses 10 cups. Then 10/(2[tex]\frac{1}{2}[/tex]) = 4, meaning he used 4 times the amount of sugar than in the original. Using that, just multiply [tex]\frac{1}{2}[/tex] by 4 to get 4 times the vanilla of the og recipe, which equals 2 tsp.

if n = 4, preal =0.80 in the direction predicted, and a = 0.051 tail, using the sign test, the power is:______
Answer:
0.0000
Step-by-step explanation:
The sign test can be defined as a statistical method which can be used to test for consistent differences that are in existence between pairs
Now If N is 4, Preal is 0.80 in the predicted direction, and this is a 0.05 1-tail. Using the sign test, the power is going to be 0.0000.
The Answer is :
power = 0.0000
