ZA and ZB are vertical angles with mZA= x and mZB = 5x – 80. What is mA? Enter your answer in the box.
Answer:
20
Step-by-step explanation:
vertical angles are equal. meas. of angle a = meas. of angle b
x=5x-80
x+80=5x
80=4x
20=x
Answer:
A = 80
Step-by-step explanation:
If they are vertical angles, they are equal.
5x - 80 = x Add 80 to both sides
5x - 80 + 80 = x + 80
5x = x + 80 Subtract x from both sides
5x - x = x - x + 80
4x = 80 Divide by 4
4x/4 = 80/4
x = 20

48% of US adults have very little confidence in newspapers you randomly selected 10 US adults. Find the probability that the number of US adults who have very little confidence in newspapers is exactly 5
Answer:
[tex]P(x = 5) = 0.2441[/tex]
Step-by-step explanation:
Given
[tex]p = 0.48[/tex] --- proportion that have very little confidence
[tex]n = 10[/tex] --- sample
Required
Determine the probability that exactly 5 have very little confidence
This question will be solved using binomial probability:
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
In this case: x = 5.
So, we have:
[tex]P(x = 5) = ^{10}C_5*0.48^5(1-0.48)^{10-5}[/tex]
[tex]P(x = 5) = ^{10}C_5*0.48^5*0.52^5[/tex]
[tex]P(x = 5) = 252*0.48^5*0.52^5[/tex]
[tex]P(x = 5) = 0.2441[/tex]

Out of seniors at a local high school, 60% went on the senior trip. At the hotel , one room was reserved for every 4 students . How many rooms were reserved for the students
Answer:
Number of rooms reserved for the students are - 90 .
Step-by-step explanation:
Firstly ,
As we know 60% of the 600 students went on the trip,
Then ,
Number of students went on the trip = 60% of 600
= [tex]\frac{60}{100}\times600[/tex]
= 360
Now ,
Given - One room is reserved for 4 students ,
Therefore , Number of rooms for 360 students = [tex]\frac{360}{4}[/tex]
= 90
Hence , the answer is 90 rooms reserved for the students.

An angle measures 32 degrees. Through what fraction of a circle does the angle turn? I need help !!!!!!!!
Answer:
4/45
Step-by-step explanation:
The sum of angles in a triangle is 360 degrees
If the angle measures 32 degrees, the fraction can be represent as 32/360
32/360 has to be converted to its simplest form. To this divide both the numerator and the denominator by 8. This gives 4/45
EASY! Please help, I will give brainilst if best explained
Answer:
A
Step-by-step explanation:
You convert each fraction to have the same decimal to find the LCD of both denominators
4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common
You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4
2 15/20 and 5 16/20
Subtract them and their is your answer

Answer:
4
Step-by-step explanation:
The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.
Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.
Solving that equation will give you b=-7
That means the y-intercept is -7.
The equation would then be y=4x-7

The combined area of a square and a rectangle is 33 square meters. The width of the rectangle is 1 meter more than the length of one side of the square and the length of the rectangle is 3 meters more
than its width.
a) Calculate the dimensions of the rectangle and its perimeter
b) Calculate the dimensions of the square.
Answer:
4 m = width of the rectangle.
6 m = length of the rectangle
20 m = perimeter of rectangle
3 m = side of the square
Step-by-step explanation:
Let s = length of side of square
s + 1 = width of rectangle
s + 3 = length of rectangle
Area of rectangle = (s + 1)(s + 3)
Area of square = [tex]s^{2}[/tex]
So, (s + 1)(s + 3) + [tex]s^{2}[/tex] = 33
[tex]s^{2}[/tex] + 4s + 3 + [tex]s^{2}[/tex] = 33
2[tex]s^{2}[/tex] + 4s - 30 = 0
2([tex]s^{2}[/tex] + 2s - 15) = 0
2(s + 5)(s - 3) = 0
s = -5 or s = 3
Length of a side cannot be negative, so -5 is ignored
3 m = side of the square
4 m = width of the rectangle
6 m = length of the rectangle
2(4) + 2(6) = 8 + 12 = 20 m = perimeter of rectangle
16x – 12 = 30x – 8 solve
Answer:
-2/7
Step-by-step explanation:
solve for x so -12+ 8 = 30x - 16x so -4 = 14x so x = -4/14, so x = -2/7
Answer:
x=-2/7
Step-by-step explanation:
you have to let x be on one side so you subtract -30x to each side.
16x-30x-12=30x-30x-8
-14x-12=-8
now you gotta add 12 to each sides to delete -12.
-14x-12+12=-8+12
-14x=4
divide -14/14x=14/4
-x=2/7
x=-2/7
hope this helps!

The grades on a math midterm at Springer are roughly symmetric with \mu = 78μ=78mu, equals, 78 and \sigma = 5.0σ=5.0sigma, equals, 5, point, 0. Omar scored 646464 on the exam. Find the z-score for Omar's exam grade. Round to two decimal places.
Answer:
-2.8
Step-by-step explanation:
Given that:
Mean, μ = 78
Standard deviation, σ = 5
Omar's score, x = 64
The Zscore of Omar's score :
Zscore = (x - μ) ÷ σ
Zscore = (64 - 78) / 5
Zscore = - 14 / 5
Zscore = - 2.8
Hence, Omar's exam score is - 2.8
Answer:
-2.8 is correct

|3.3| = ____
Answer:
it stays the same
Step-by-step explanation:
if it was -3.3 then it would change to 3.3 but because it is already in the positives it stays a positive plz double chesk if needed tho
Answer:
[tex]3.3[/tex]
Step-by-step explanation:
Absolute value expresses the distance of a number from 0.
For this reason, no matter if the number is negative or positive, the absolute value of it will always be positive.
In this case, it is simply [tex]|3.3|=3.3[/tex].
An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²
_______________________________________________
The answer is 35.1 cm².
Hope this helps; have a great day!

Answer:
y=mx+b
so
y=8x+3. the second answer choice
Answer:
y=8x+3
Step-by-step explanation:
we are given the slope (m) as 8 and the y intercept (b) as 3.
The given options are in y=mx+b format.
Use your given information to write the equation in y=mx+b form
we know that m (slope) is 8. The equation so far is y=8x+b
we know that b (y intercept) is 3. So the equation of the line is y=8x+3

Consider the polynomial function h(x) = -2x^5+ 8x^4
2x^2+15.
What is the end behavior of the graph of h ?
Answer: B
Step-by-step explanation:
Applying limits, it is found that the end behavior of the graph is:
B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].
The function is:
[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]
To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:
[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]
Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]
[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]
Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]
Hence, option B is correct.
