Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = 4x - 10
y = x + 2
Step 2: Solve for x
Substitution
Substitute in y: 4x - 10 = x + 2Subtract x on both sides: 3x - 10 = 2Add 10 on both sides: 3x = 12Divide 3 on both sides: x = 4Step 3: Solve for y
Define equation: y = x + 2Substitute in x: y = 4 + 2Add: y = 6Can someone help me I need help
Answer:
The answer would be C (The decimal form has 2 didgets that repeat :)
Step-by-step explanation:
Happy Holidays!
Answer:
It would be the second one
Step-by-step explanation:
If you divide them the 15 and 24 you get 0.625
So the decimal terminates after 3 digits
Another way to do it instead of being confused about what they mean by turn it in to a decimal. you can most of the time divide the 2 numbers and get your answer from there.
Hope this helped!!!!!!

Because the sample size is 9, do you need to be concerned about the shape of the population distribution when conducting the t test in (a)? Explain. Choose the correct answer below. A. With a small sample size, it is difficult to evaluate the assumption of a skewed distribution. However, the distribution may be asymmetric because the mean and the median are not close in value. B. With a small sample size, it is difficult to evaluate the assumption that the distribution follows the Student's t distribution. However, the distribution may be symmetric because the mean and the median are close in value. C. With a small sample size, it is difficult to evaluate the assumption of normality. However, the distribution may be symmetric because the mean and the median are close in value.
Answer:
The answer is "Option C".
Step-by-step explanation:
The sample size is 9, so it is difficult to evaluate the conformity assumption with just a little sample to come in the form of a population demographics whenever the t-test is carried out in a. The distribution can be symmetrical since the average or median are close in price, that's why choice C is correct.
The admission fee at an amusement park is $3.25 for children and $5.00 for adults. On a certain day, 278
people entered the park, and the admission fees collected totaled $1201. How many children and how
many adults were admitted?
Answer:
Children= 108
Adults= 170
Step-by-step explanation:
First, we structure the two equations:
x= number of tickets for children
y= number of tickets for adults
3.25x + 5y= 1,201
x + y= 278
Now, we isolate x in one equation and substitute in the second one:
x= 278 - y
3.25*(278 - y) + 5y= 1,201
903.5 +1.75y = 1,201
y= 297.5/1.75
y= 170
Finally, we determine the value of x:
x= 278 - 170
x= 108
Prove:
3.25*108 + 5*170= 1,201
170 + 108= 278

Which property of real numbers is illustrated by the equation?
9514 1404 393
Answer:
additive inverse
Step-by-step explanation:
The equation shows that the sum of a number and its additive inverse is zero. This is the additive inverse property.
_____
Additional comments
This property is used, together with the identity property of addition, to solve equations by making terms disappear where you don't want them.
Example:
x + 1 = 3
We would like to remove the +1 in order to find the value of x. Using the additive inverse property, we add the additive inverse of +1 to both sides of the equation.
x +1 -1 = 3 -1
The additive inverse property tells us the sum of +1 and -1 is zero, so this becomes ...
x +0 = 2
The additive identity property tells us the sum of x and 0 is simply x, so ...
x = 2
$30 per hour it cut off pls help i give brainlest if it’s correct
Answer:
t = 4 h
Step-by-step explanation:
Painter A initial fee 40 $ and each hour charge 45 $
Painter B initial fee 100 $ and each hour charge 30 $
The equations for painters are straight lines.
The initial fee is the intercept of the line with the y-axis ( painters receive 40 and 100 $ respectively and they have done nothing.
The equation for a straight line is:
y = m*x + b where m is the slope and b the intercept with the y-axis
Then
Painter A when x = 0 y = b = 40
And each hour of work cost 45 $ then f x = t in hours
The equation for Painter A is y = 45*t + 40
Similarly, the equation for Painter B is
y = 30*t + 100
We have a two equations system, the solution will indicate when the two painters will charge the same amount of money
y = 45*t + 40 (1)
y = 30*t + 100 (2)
Equation 1 - equation 2
0 = 15*t - 60
15*t = 60
t = 60/15
t = 4 h
Since insulin u-100 is 100 units/mL,which of the following shortcuts can be used to convert a dose of u-100 insulin given in units, to mL
Answer:
The shortcuts is
Divide number of units by 100
Step-by-step explanation:
From the question we are told that
insulin u-100 is [tex]L = 100 \ unit /mL[/tex]
From the data given above we see that
100 units of insulin u-100 is contained in 1 mL
So 1 unit of u-100 is contained in x mL
=> [tex]x = \frac{1}{100} \ mL[/tex]
This means that a unit of insulin u-100 occupies [tex]x = \frac{1}{100} \ mL[/tex]
So we can represent a single unit of insulin u-100 as [tex]\frac{1}{100} \ mL[/tex]
Now if 1 unit of insulin u-100 is represented as [tex]\frac{1}{100} \ mL[/tex]
Then y unites of insulin u-100 is represented as z
So
[tex]z = \frac{y}{100} \ mL[/tex]
From the above calculation we can see that the shortcuts to convert u-100 insulin given in units, to mL is to divide number of units by 100

Write an equation in point-slope form of the line that passes through the point (4 - 5) and has a slope of 2.
Answer:
y=2x-13
Step-by-step explanation:
According to y- y1= m( x-x1),
y-(-5)= 2 ( x-4)
So, y=2x -13
Step-by-step explanation:
y - 5 = 2
x - 4
y - 5 = 2x - 8
y = 2x - 8 + 5
y = 2x - 3
Define communicative, associative and distributive property below
Step-by-step explanation:
okay so The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The property holds for Addition and Multiplication, but not for subtraction and division.
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like!.
distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

I will give Brainliest for correct answer
Answer:
If not mistaken c
Step-by-step explanation:
(1 point) Suppose the chance a player will win a single round of a certain gambling game is (supposedly) 25%, independently of other rounds. You play 100 rounds and win only 18 times. This is less than the expected value. Was it just bad luck
Answer:
It was simply a case of bad luck.
Step-by-step explanation:
The predictable win outcome from playing a round of a certain gambling game = 25%
If one plays 100 rounds, the predictable wins should be 25 (100 * 25%)
If the actual wins = 18, which is less than the predictable wins of 25, the actual result is less than the expected value or outcome by 7. This is simply a case of bad luck. Bad luck is defined as an unpredictable outcome that is unfortunate. It is when the predicted (expected) outcomes, 25 wins, are more than the unpredicted (actual observed) outcomes, 18 wins.
