(ILL MARK YOU AS BRAINLEST) The ratio of the interior angles of a triangle is 1: 1: 4 What are the angles measures? Write the angel measures from least to greatest.
Answer:
30 degrees,30 degrees120, degrees
Step-by-step explanation:
The ratio of the angles is 1:1:4.
Let’s represent the angles by 1x, 1x, and 4x.
The sum of the interior angles of a triangle is 180°.
1x + 1x +4x = 180 Combine like terms.
6 x = 180 Divide each side by 6
x = 30°
1x=1*30=30 degrees
1x=1*30=30 degrees
4x=4*30=120 desgrees
Answer:
30, 30, 120
Step-by-step explanation:
Basic properties of a triangle:
Triangles have 3 sides.The sum of the interior angles of a triangle will always be equal to 180°.The problem:
Find the angle measuresList them in least to greatestGiven information:The ratio of the angles' values are 1:1:4.To solve:
To solve this type of problem, think of the ratio as a variable, x.The ratio would be x:x:4xGiven that revised information, the sum of the interior angles is 6x.Since the sum of the interior angles of a triangle is 180°, 6x = 180°To find x as an individual value, divide both sides of the equation by 6:- 6x = 180- x = 30 Now, to find the angles' values, use the value of x in the ratio to solve:30 : 30 : 120The values of the ratio are your angles!Finally, list from least to greatest and the question is completely answered!A study of 420,027 cell phone users found that 133 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0414% for those not using cell phones. Complete parts (a) and (b). a. Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system.
Answer: (0.00027144, 0.00036176)
Step-by-step explanation:
The sample proportion of cell phone users who develop cancer of the brain or nervous system = [tex]\dfrac{133}{420027}=0.0003166[/tex]
Sample size : 420027
Confidence interval for p: [tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex]= sample proportion , n= sample size , z* = crirical z value.

Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
If any 2 parallel lines are cut by a transversal line , then :-
its corresponding angles on same side [a pair of an interior angle and it's corresponding exterior angle (but not its adjacent exterior angle)] are equal.its alternate interior angles are equal.its alternate exterior angles are equal.__________________________________________________________
Q1)
According to the figure on the right side of the question paper ,
∠2 & ∠8 are interior angles on the same side∠2 = ∠7 (∵ Alternate interior angles are equal)So,
∠7 + ∠8 = 180°
⇒ ∠2 + ∠8 = 180° (∵ ∠2 = ∠7)
Hence , we can conclude that interior angles of same side are supplementary angles. So the correct option is A.
Q2)
According to the figure on the question paper ,
∠5 & ∠3 are exterior angles on the same side∠1 = ∠5 (∵ Corresponding angles are equal)So ,
∠1 + ∠3 = 180°
⇒ ∠5 + ∠3 = 180° (∵ ∠1 = ∠5)
Hence , we can conclude that exterior angles on the same side are supplementary angles. So , the correct option is A.
Q3)
According to the figure , (∠2 , ∠7) & (∠1 , ∠8) are alternate interior angles. But as (∠1 , ∠8) is there as an option , so the correct option is D.
Q4)
According to the figure , m∠1 = 129°.
Also , ∠1 & ∠7 are interior angles on the same side.
⇒ They are supplementary angles.
⇒ ∠1 + ∠7 = 180°
⇒ ∠7 = 180° - 129° = 51°
So , the correct option is B.
Q5)
According to the figure , m∠2 = 3x - 10 and m∠6 = 2x + 20
Also , ∠2 = ∠6 (∵ Corresponding angles are equal)
⇒ 3x - 10 = 2x + 20
⇒ 3x - 2x = 20 + 10
⇒ x = 30
So , ∠2 = 3×30 - 10 = 80° = ∠6 (∵ Corresponding angles are equal)
Hence , the correct option is D.
1. Which of the following sets of integers is arranged in order from LEAST to GREATEST?
Oi-1.5 - 9
O (1. - 5. - 10)
O (12. - 8,0)
O { - 13. - 12,9)
Answer:
Last option:
(-13, -12, 9)
Step-by-step explanation:
Here you need to look at a number line.
(an infinite line with the zero in the middle, at the left we have the negative numbers which increase to the left, and at the right, we have the positive numbers that increase to the right)
for any two pair of numbers in the number line, the number at the right is larger than the number at the left.
So for example, -10 is at the left of -3
Then:
-10 < -3.
Then a set is ordered from least to greatest if:
first we have the largest negative numbers
then the smaller negative numbers
then the zero (if there is a zero)
then the smaller positive numbers
then the largest positive numbers.
The only set that meets this condition is the last one:
(-13, -12, 9)
Why the others not meet this condition?
in the first one we have -9 after 5, and we know that -9 < 5
in the second one we actually have an order from greatest to least.
in the third one we have -8 at the right of 12, and we know that -8 < 12

Jennifer recently finished paying off her $30,000 fixed-rate student loan. She paid $303.73 per month for 10 years to
complete the payments. How much interest did she pay over the duration of the loan? Round to the nearest cent
Answer:
$6,447.60
Step-by-step explanation:
Since Jennifer's monthly payment was $303.73 and she paid this amount each month for 10 years, multiply the monthly payment by the number of months in 10 years, 120, to determine the total amount that she paid.
$303.73×120=$36,447.60
Now, subtract the stated amount of the loan from the total amount paid to find the amount of interest that was paid.
$36,447.60−$30,000=$6,447.60
Therefore, Jennifer paid $6,447.60 in interest through the duration of the loan.
The total amount of interest of loan paid by Jennifer is $ 6447.60
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount of interest of loan paid by Jennifer be = A
So , the equation will be
Now , the amount she took as loan on fixed rate = $ 30,000
The amount of money Jennifer paid per month = $ 303.73
The total duration of time Jennifer paid off the loan = 10 years
10 years = 10 x 12 months
10 years = 120 months
So , the total amount paid back by Jennifer = Amount of money she paid per month x 120 months
Substituting the values in the equation , we get
The total amount paid back by Jennifer = 303.73 x 120
The total amount paid back by Jennifer = $ 36,447.6
Now , the loan interest amount paid by Jennifer A = total amount paid back by Jennifer - amount she took as loan on fixed rate
Substituting the values in the equation , we get
The loan interest amount paid by Jennifer A = $ 36,447.60 - $ 30,000
The loan interest amount paid by Jennifer A = $ 6447.60
Therefore , the value of A is $ 6447.60
Hence , The total amount of interest of loan paid by Jennifer is $ 6447.60

if f(x)=6x-8, then f^-1(x)=
Answer:
f(x) is another way to write y.
You have y = 6x - 8.
To find the inverse, switch the x and the y and solve for the new y.
Switching gives you x = 6y - 8.
You add 8 to both sides to give you 6y = x + 8.
Divide both sides by 6 gives you the inverse as y =1/6x + 4/3

The average length of a flight by regional airlines in the United States has been reported as 464 miles. If a simple random sample of 30 flights by regional airlines were to have a mean of 476.9 miles and a standard deviation of 42.8 miles, what would be the test statistics (t-value) if we are to test whether this tend to cast doubt on the reported average of 464 miles or not
Answer:
The t-value is t = 1.65.
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
The average length of a flight by regional airlines in the United States has been reported as 464 miles.
This means that the null hypothesis is [tex]H_{0}: \mu = 464[/tex].
Simple random sample of 30 flights by regional airlines were to have a mean of 476.9 miles and a standard deviation of 42.8 miles
This means that [tex]n = 30, X = 476.9, s = 42.8[/tex]. So
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{476.9 - 464}{\frac{42.8}{\sqrt{30}}}[/tex]
[tex]t = 1.65[/tex]
The t-value is t = 1.65.
t = p + 50
The variable p represents the number phone calls she routes, and the variable t represents
the number of minutes she is on the phone. In all, how many phone calls does Shivani have
to route to spend a total of 93 minutes on the phone?
find the measure of angle A
Answer:
so 2x+3x+130=180
so 5x+130=180
5x=50
so 2x =20
3x which is angle a is equal to 30 degree
Answer:
The measure of angle A is 30 degrees.
Step-by-step explanation:
Since all triangles are equal to 180 degrees, you take set up an equation where u add 2x and 3x to get 5x and u add that to 130 and set it equal to 180
2x+3x+130=180 ( combine like terms)
5x=50 (subtract 130 from both sides to isolate our variable which is x)
x=10 (divide both sides by 5 to get rid completly isolate our variable)
Now we know x=10 you can plug that in as our x value so 3x becomes 3*10 which equals 30 which is your answer.

For which of the options is 2 an element
[tex]A.\ \{2, 3, 4, 5, ...\}[/tex]
The elements of this set starts from 2, then 3 and continues as thus.
Hence: 2 is an element
[tex]B.\ \{0, 1, 4, 9, ...\}[/tex]
From the given elements in the above set, 2 is not listed.
Hence: 2 is not an element of this set
[tex]C.\ \{2, \{2\} \}[/tex]
Here, 2 is listed as an element, 2 is also listed as a subset.
Since 2 is listed as an element, then 2 is an element of the set.
[tex]D.\ \{\{2\}, \{\{2\}\}\}[/tex]
Here, 2 is listed as a subset of {2} and also as a subset of subset of {{2}}.
Since 2 is not listed as an element itself, then 2 is not an element of the set.
