Find the measures of the indicated angles.
Answers
t=62 v=118 w=42 I think
Step-by-step explanation:
first, find the value of angle t
angles of a triangle add up to 180.
with this, we can set up the equation
180 = t + 62 + 56
t = 62
to find angle w, find the sum of the top angles
25 + 56 = 81
again, sum of angles in a triangle adds to 180.
since we have the bottom right angle and the top angle, we can find the bottom left angle
180 = 56 + 62 + w
w = 37
finally we can find angle v
180 = 25 + w + v
180 = 25 + 37 + v
v = 118
another approach would be to find angle v after finding angle t.
because the two angles are supplementary, they add up to 180
angle v + angle w = 180

basically degrees of freedom are related to sample size (n-1). If the df increases, it also stands that the sample size is increasing; the graph of the t-distribution will have skinnier tails, pushing the critical value towards the mean.
Two less than three times a number is equal to 19. What is the number?
Answers
The best way to approach a word problem like this
is to break it down into pieces, so we can understand it fully.
In this problem, we have a number, which we don't know.
We can use any variable to represent it.
So let's use the variable n to represent it.
"Two less than three times a number" means 3n - 2.
A common mistake is for students to put 2 - 3n.
However, the word "less than" switches the order around.
So we have 3n - 2 = 19.
Solving from here, we add 2 to both sides to get 3n = 21.
Now divide both sides of the equation by 3 and we have n = 7.
So the number is 7.

How are the angles of an equilateral triangle related?
Please explain so a smol brained person can understand
Answers
There are 180 degrees in total inside a triangle.
If something is equilateral that means that all the angles are equal.
180/3 equals 60 degrees.
That means that all angles of an equilateral triangle are always equal to each other and if you must know, are 60 degrees

You have saved $1350 and are now going to invest it. The account you have chosen will compound continuously and after 10 years you will have $1462. What interest rate will the account give you?
Answers
Answer:
The account interest rate is 0.80%
Step-by-step explanation:
A=P(1+r/100)^10
1462=1350(1+r/100)^10{divide both sides by 1350}
1462/1350=(1+r/100)^10{find the 10th root of both sides}
1.00800=1+r/100{multiply through by 100}
100.800=100+r
r=100.800-100
r=0.80%
Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) - 13?
A) The graph of y = f(x) will shift up 13 units.
B) The graph of y = f(x) will shift right 13 units.
C) The graph of y = f(x) will shift left 13 units.
D) The graph of y = f(x) will shift down 13 units.
Answers
Answer: D) The graph of y = f(x) will shift down 13 units.
Step-by-step explanation:
Let's define the transformations of translations.
If we start with a function f(x):
For A > 0.
An horizontal translation of A units to the right is written as g(x) = f(x - A)
An horizontal translation of A units to the right is written as g(x) = f(x + A).
A vertical translation of A units up is written as g(x) = f(x) + A
A vertical translation of A units down is written as g(x) = f(x) - A.
In this question we have the transformation:
y = f(x) - 13
This is a translation of 13 units down, then the correct option is:
D) The graph of y = f(x) will shift down 13 units.

Answers
Answer: pretty sure it's the number you multiply by 4 is 17
Step-by-step explanation:
when you multiply 4 and 16 you'll get 64 then you subtract 19 and get 45 which is less than 47 so by reasoning if you were to multiply 4 and 17 you'll get 68 then you subtract 19 from 68 and you should get 49 ( you didn't include how much greater than 47 the number should be but the safest bet would be to use 17)

Find the value for x.
5x - 12
3x + 30
48
Answers
is this the way the question is laid out? is there an equal sign anywhere
The value of x will be;
⇒ x = 3.75
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 5x - 12 + 3x + 30 = 48
Now,
Solve the expression for x as;
The expression is,
⇒ 5x - 12 + 3x + 30 = 48
⇒ 8x - 12 + 30 = 48
⇒ 8x + 18 = 48
Subtract 18 both side as,
⇒ 8x - 18 = 48 - 18
⇒ 8x = 30
Divide by 8 as;
⇒ x = 30/8
⇒ x = 3.75
Thus, The value of x will be;
⇒ x = 3.75

Find the equation of the line passing through the points (3,1) and (7,-7)
Answers
Answer:
y = -2x + 7
Step-by-step explanation:
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the point (3,1) and (7,-7), calculate the slope:
[tex]\displaystyle m=\frac{-7-1}{7-3}[/tex]
[tex]\displaystyle m=\frac{-8}{4}=-2[/tex]
m = -2
Now we use any of the given points: (3,1) and substitute in the equation of the line:
y - 1 = -2 ( x - 3 )
Multiplying:
y - 1 = -2x + 6
Adding 1:
y = -2x + 7

A person is interested in studying the amount of time (in minutes) people spend on social media in day. The following data is collected from a sample of 12 people: 45, 60, 25, 55, 75, 90, 100, 120, 105, 80, 0, and 220. (a) Calculate the mean, variance and standard deviation and 5
Answers
Answer:
81.25 ; 3091.48 ; 55.60
Step-by-step explanation:
Given the data :
45, 60, 25, 55, 75, 90, 100, 120, 105, 80, 0, 220
The mean :
ΣX/n ; n = sample size
ΣX = 45+60+25+55+75+90+100+120+105+80+0+220 = 975
n = 12
Mean = 975 / 12 = 81.25
The variance :
Σ(X - m)^2 / n - 1
Using calculator to save computation time :
The variance : (34006.24997 / 11)
Variance = 3091.48
The standard deviation :
Sqrt(Variance) = sqrt(3091.48) = 55.60
