Answer:
x = 612
Step-by-step explanation:
x = 2(y + z) Divide by 2 to isolate y + z
x/2 = y + z Set up the sum of three numbers
x + y + z = 918 Substitute x / 2 for y + z
x + x/2 = 918 Combine like terms
3/2 x = 918 Multiply both sides by 2/3
2/3 * 3x/2 = 2/3 * 918
x = 612

Fatima will take an UBER to the movie
theater. She will pay a one time fee of
$5 plus $2.65 per mile. Which equation
can be used to find y, the total cost of
the trip, if x represents the number of
miles of the trip?
A. y = 5x + 2.65
B. y = 5x - 2.65
C. y = 5 + 2.65x
Need
D. y = 5 - 2.65x
Answer:
A
Step-by-step explanation:
If x is the mile then you pay 5 dollars a mile or 5x. The flat fee is 2.65 so we add it and since it's not per mile we don't add an X.

Find the area. Do not include the units
Answer:
19.95cm²
Step-by-step explanation:
Okay, so I don't know what "do not include the units means", so I'm sorry if this is wrong, but the formula for the area of a parallelogram is height x width. Lucky for us, we have both so we just have to plug:
3.4 x 5.7 = 19.95
So, the area of the parallelogram is 19.95cm²

Trigonometry
Find the Reference Angle (17pi)/10
17π1017π10
Since the angle 17π/ 10 is in the fourth quadrant, subtract 17π/10 from2π.
2π−17π/10
The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].
What is coterminal angle?Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.
Angles are considered to be in standard position if the initial side is on the positive x-axis and the vertex at the (0,0) point of the Cartesian plane. All angles generated that share the same terminal side are coterminal angles. These are angles that have differences of multiples of 360n or n2pi where n is an integer.
A coterminal angle is found by simply adding or subtracting 360 and its multiples.
The coterminal angles of 20 degrees for example are 20 + 360 = 380 or 20 - 360 = -340. This may continue by adding or subtracting 360 each time.
To get coterminal angles, you simply have to add or subtract 2[tex]\pi[/tex].
According to this problem,
We are looking for a coterminal angle that is between 0 to 2[tex]\pi[/tex], so we will add [tex]2\pi \ to \ \frac{-17\pi }{10}[/tex].
= [tex]\frac{-17\pi }{10} +\frac{20\pi }{10}[/tex]
= [tex]\frac{-17\pi +20\pi }{10}[/tex]
= [tex]\frac{3\pi }{10}[/tex]
Hence,
The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].

Find the quadratic root of 3x2-4x+2=0
Answer:
Step-by-step explanation:
The question on the top is
A student spins The spinner once and rolls the 1-6 number cube once. The second question is
What is the probability a student spends an even number and rolls an odd number, written as a percentage?
10 points this is due tomorrow.
Answer:
Option C
Step-by-step explanation:
For the spinner,
Probability of spinning an even number = [tex]\frac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
Favorable outcomes = even numbers on the spinner
= 3
Total outcomes = Total numbers on the spinner
= 6
Probability of spinning an even number = [tex]\frac{3}{6}[/tex]
= [tex]\frac{1}{2}[/tex]
For the cube,
Total outcomes = total numbers on the dice = 6
Favorable outcome = Odd numbers on the dice = 3
Probability of rolling an odd number on rolling a cube = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
Probability of spinning an even number on spinner and an odd number on a cube = [tex]\frac{1}{2}\times \frac{1}{2}[/tex]
= [tex]\frac{1}{4}[/tex]
Percentage probability = [tex]\frac{1}{4}\times 100[/tex]
= 25%
Option C is the answer.

180-104 is 76 76-10=66 66/2 is 33
Answer: x = 33
Step-by-step explanation:
Well since that line is basically equal to 180 all you have to do is plug in those numbers for x. Since 33 + 10 = 43 Alll you gotta do is add that up. So we have 104 + 33 + 43 = 180. I’m not the best at explaining things but I hope this helped :)
Re-write this question to make it a statistical question: How old am I?
Answer:
How many years has it been ever since I was born?
Step-by-step explanation:
Definition of a statistical question :
A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer. For example, "How many minutes do 6th grade students typically spend on homework each week?" is a statistical question.
Find the total surface area of these rectangular boxes when they are (i) lidless and (ii) hollow.
a. length = 15cm, breadth = 10cm, height = 6cm
Answer: 450 cm squared if not including the inside surface
900 cm squared if including the inside suface
Step-by-step explanation:
A=2(wl+hl+hw)
A=2(150+90+60)
A=2(300)
A=600
but we have a lidless box so we need to subtract the lid...
600-(wl)=
600-(150)=450
If we are including the inside surface it would double as we would be covering both exposed surfaces of bottom, 2 ends, and 2 sides....
450x2=900
The surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
(i) The surface area will be calculated as,
A=2(wl+hl+hw)
A=2(150+90+60)
A=2(300)
A=600
But we have a lidless box so we need to subtract the lid.
600-(wl)=
600-(150)=450
(ii) If we are including the inside surface it would double as we would be covering both exposed surfaces of the bottom, 2 ends, and 2 sides.
450x2=900
Therefore, the surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.

Find five numbers so that the mean, median, mode and range are all 4.
Answer:
The set of five numbers would be {2,4,4,4,6}
Answer:
The example set could be:
S
=
{
2
,
4
,
4
,
4
,
6
}
See explanation.
Explanation:
First you can notice that if the set was:
S
1
=
{
4
,
4
,
4
,
4
,
4
}
then it would fulfill 2 conditions: mean and median, but
the set does not have the mode because all numbers are the same,
the range is zero (again all numbers are the same)
To have the mode the set would have to have at least one element different from
4
, but if we changed only one element the mean would change, so at least two numbers need to be changed to keep mean equal to
4
..
Now to get the range the difference between the changed numbers should be
4
. That leads us to adding two to one number and subtracting two from the other.
Finally we can get the set from the answer.
sharon bought a $2,100 high definition television set on a six month rent to own plan. the down payment was 10%. what was the dollar value of the down payment? her monthly payments were $75 per month. if she decides not to buy the HDTV after the six months, what was her cost to rent it?
Answer:
Total Sharon spent $660 for the tv
The down payment was $210
The amount that she paid for rent after 6 months is $450
Step-by-step explanation:
To find out how much her down payment was you would need to find out how much 10% of $2,100 is which is $210, so you know her down payment was $210.
Then you would find out the total cost of rent is after 6 months so you would do 6 times $75 which is $450. So if she decides to not buy it then after 6 months she would have spent $450 to rent it.
And total she would have spent $660 which you can find out by doing $450 + $210 = $660.

what is z + 5x3 because im lost
Answer:
z + 15
Step-by-step explanation:
In this example, it's not an equation (it doesn't "equal" anything), just an expression. We cannot combine z with the actual numbers. It is a variable, so it could be combined with other terms including z, like if it said 2z + z + 5 x 3.
The only thing you can do with your expression is "combine like terms" by multiplying 5 and 3 to get 15.

The cube root function , has no domain restrictions. The domain of the cube root function is all real numbers, or ℝ .
What is domain ?The domain of a function is the complete set of possible values of the independent variable.
The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
When finding the domain, remember:
The denominator (bottom) of a fraction cannot be zero.
The number under a square root sign must be positive in this section.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Domain: (- ∞ , ∞) , {x | x ∈ [tex]\mathbb{R}[/tex]}

What is independent t-test?The independent t-test is a defined as an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.
Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect" So, If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.
T test is used to compare group means is one of the most common tests and is used to determine whether the means of two groups are equal to each other.
We perform one sample z-test;
One sample z-test is performed if the sample size is large enough (n > 30) and we want to know if the sample comes from the specific population.
