Answer:
x = 25
Step-by-step explanation:
The sum of the angles of a triangle add to 180
We have a right triangle so one of the angles is 90degrees
90 + 2x + x+ 15 = 180
Combine like terms
105+3x = 180
Subtract 105 from each side
105+3x-105 = 180-105
3x = 75
Divide by 3
3x/3 = 75/3
x = 25
Answer:
So the inside of a triangle will equal 180 degrees so, you would set up your equation as 90+2x+(x+15)= 180
you then solve that equation let me know if you didn't get the equation solved.

Fast food chain surveyed a random sample of students to determine what pizza they prefer cheese pizza was referred by 840 students pepperoni pizza was preferred by 28 students based on the results how many of the 340 students can be expected to prefer cheese pizza
Answers
Answer: 200 students
Step-by-step explanation:
Here is the complete question:
Fast food chain surveyed a random sample of students to determine what pizza they prefer. Cheese pizza was preffered by 40 students pepperoni pizza was preferred by 28 students. Based on the results how many of the 340 students can be expected to be for cheese
Number of studensts that prefered Cheese pizza = 40
Number of students that prefered pepperoni pizza = 28
Total number of students = 68
Fraction for those that prefer cheese = 40/68 = 10/17
We then multiply the fraction gotten by 340. This will be:
= 10/17 × 340
= 10 × 20
= 200 students
Write the equation of a line that is parallel to y=0.6x+3 and that passes through point (-3,-5).
Answers
So you have
y=0.6x+b and you plug in your point (-3,-5) into the equation and it would be y=-5 and x=-3 so you would say
-5=0.6(-3)+b and you would solve for b
-5=-1.8+b
So b=-5+1.8
b=-3.2
So your equation in slope intercept form would be y=0.6x-3.2

In a survey, 61 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $39 and standard deviation of $3. Find the margin of error for a 99% confidence level.
Answers
Answer:
0.989
Step-by-step explanation:
The formula for Margin of Error is:
z × Standard deviation/√n
Where
z = z score for 99% confidence Interval
= 2.576
n = 61 people
Standard deviation = $3
Hence,
Margin of Error
= 2.576 × 3/√61
= 0.989

We can convert 63% directly to a decimal:
63% = 0.63
Then, doing the calculation by hand or with a calculator, we find
63% of 78 = 0.63 x 78 = 49.14
So the final answer is
63% of 78=49.14
You can round the decimal, if you're looking for a whole number, to about 49%.
A hardware store sold 630 lawn mowers in one year. If 441 lawn mowers were purchased in the spring, what is the ratio of the number of lawn mowers purchased in the spring to the number purchased during the entire year?

On x - axis represent the pounds and y - axis represent the cost.
On y- axis graph intersect at y= 6 and on x- axis graph intersect at x= 8.
Now from the graph, it is observe that,
(1)The movie ticket is $6. So, it is true.
(2) Javier earn up to $8 peeling potatoes for his mother. Hence it is false.
(3)Javier's mother pays him $0.75 for each pound of potatoes he peels. Thus, it is true statement.
(4)Javier dose not use any of his own money towards the purchase of the tickets when he peels 8lb of potatoes. Hence it is true statement.
(5)Javier only need to peel 2 lbs of potatoes to not use any of his own money. Hence it is false statement.

ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
Because your triangle has more than two angles that are congruent, and more than one side that are congruent, it more than fits the theorms.

Which equation shows that 5 is a factor of 45?
Choose 1 answer:
A: 45 = 5x9
B: 45 = 225 ÷ 5
C: 45 = 5 + 40
D: 45 = 50 - 5
Answers
From the list of available options, the equation that shows that 5 is a factor of 45 is (a) 45 = 5 * 9
What are factors?The factors of a number are the set of numbers (less than the actual number) that can divide the original number without leaving a remainder
How to determine the equation that shows that 5 is a factor of 45?As stated above, factors can divide the original number
The numbers are given as:
45 and 5
Such that 5 is a factor.
This means that
45 = 5 * x
Where x is another factor of 45
Divide both sides of the equation 45 = 5 * x by 5
x = 9
Substitute 9 for x in the equation 45 = 5 * x
45 = 5 * 9
Hence, the equation from the list of given options that shows that 5 is a factor of 45 is (a) 45 = 5 * 9

Helen gathered data on the fuel efficiency of compact sedans. Her sample contains 80 data points, and the standard error of the mean is approximately 0.595. What is the standard deviation? Round your answer to the nearest hundredth.
Answers
Answer:
5.32
Step-by-step explanation:
It took me a while to figure this out myself, here is how I found the answer:
The question gives sample number(80) and the standard error(0.595).
To get the standard error number they use this equation:
[tex]\frac{standard-deviation}{\sqrt{sample-population} }[/tex]
So to find the standard deviation, take [tex]\sqrt{sample-population}[/tex] and times it by the standard error to get the answer.
[tex]\sqrt{80}[/tex] x 0.595 = 5.321841786449499
And then round to the nearest hundredth: 5.32

Answer:
1) y=2x+5
2) y=-2x+3
3) y=4x+2
Step-by-step explanation:
Okay so the y intercept formula is
y=mx+b
Y is a random y coordinate
m is the slope
x is a random x coordinate
b is y intercept
So first we can make the equation equal to y
Find the slope *dont forget the negatives*
When found the slope, plug it in for b and add x next to it
so now your equation would be something like
y=mx
Now for the B we just start from the origin.
And find the first coordinate to pass the y axis
Now just put it in *ex: if 0,3 is the first coordinate, put 3 as B.
now young got it!

Let’s take our function from before: f(x) = x + 2. Plug in some values for x. f(2) = 4. f(3) = 5. f(4) = 6.
Now we have a set of inputs and outputs for this function. You can write them as a set of ordered pairs, like this: (2, 4), (3, 5), (4, 6).
Like all sets of ordered pairs, these points can be plotted on a graph. If you plot
f(x) = x + 2 and connect the points, you will see that the graph is a straight line. This means that f(x) = x + 2 is a linear function.
Which of these is a set of inputs and outputs for the function f(x) = 2x + 4?
A
(1, 2), (2, 5), (3, 8)
B
(1, 4), (2, 6), (3, 7)
C
(1, 5), (1, 8), (1, 10)
D
(1, 6), (2, 8), (3, 10)
Answers
Answer:
D
Step-by-step explanation:
Plug them in
Input is the x value, or x, and Output is the y value, or f(x)
You can figure it out with only the first set of coordinates
Ima flip the equation around: 2x + 4 = f(x)
so, substitute x for the x coordinate: 2(1) +4 =f(x) = 2 + 4 = f(x) = 6
the correct y value when x is equal to 1 is 6, and only D satisfies this rule.
