The value of x for the given triangle is 4.5
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of all three angles of a triangle is always 180°
In the given triangle ABC,
∠A=(9x+16)°, ∠B=(6x+15)°
And the extrior angle ∠C=(19x+3)°
Use the external angle property,
The sum of two interior angles is equal to an exterior angle.
Therefor,
∠C=∠A+∠B
(19x+3)°=(9x+16)°+(6x+5)°

Richard’s cumulative gpa for 3 semesters was 2. 0 for 42 credits. His fourth semester gpa was 4. 0 for 14 course units. What is richard’s cumulative gpa for all 4 semesters?.
Richard earned a cumulative GPA of 2.5 in all four semesters.
Here, we know that the cumulative GPA for the first 3 semesters is 2.0
He had earned 42 credits in total in all three semesters.
Cumulative GPA = Total points earned/credits rewarded
Hence,
Total points earned in 3 semestes= 2 X 42
= 84 points
In the fourth semester,
he had earned 14 credits with a GPA of 4.0
Hence total points earned = 4 X 14
= 56 points
Therefore, total points earned in all four semesters = 84 + 56 points
140 points
Total credits = 14 + 42
= 56
Hence, the cumulative GPA of all 4 semesters
= 140/56
= 2.5 points.

If R and S are parallel lines and ∠1= 4x-3 and ∠7= 3x+4, The measure of ∠2 will be 179.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
It is given that, R and S are parallel lines and <1= 4x-3 and <7= 3x+4,
From the given figure it is obtained that R and S are parallel lines,
∠1=∠7
4x-3=3x+4
4x-3x=4+3

x=1
If the ∠1 and ∠2 are supplementary,
∠1+∠2=180
4x-3+∠2=180
∠2=180-4x+3

2) through: (4, -5) and (0, 2)
3) through: (0, 4) and (2, 1)
The equation of the line in point slope form is as follows:
y - 4 = - 1 / 7(x - 5)y + 5 = - 7 / 4(x - 4)y - 4 = - 3 / 2(x - 0)How to represent linear equation in slope intercept form?Linear equation can be represented in different form such as point slope form, slope intercept form, standard form and general form.
Therefore, equation in point slope form can be represented as follows:
y - y₁ = m(x - x₁)
where
m = slopeTherefore, let's find the point slope form of the lines.
1) through: (5, 4) and (-2, 5)
m = 5 - 4 / -2 - 5
m = 1 /- 7 = - 1 / 7
Therefore,
y - 4 = - 1 / 7(x - 5)
2) through: (4, -5) and (0, 2)
m = 2 + 5 / 0 - 4
m = 7 / -4 = - 7 / 4
Therefore,

(1,1), (2,2), (3,3), (4,4) (1,1), (1,2), (1,3), (1,4) because the dice are fair, each of the outcomes in the sample space are equally likely. what is the probability of each outcome in the sample space? enter a fraction. (b) define event a as getting a sum of 5. p(a)
The probability of each outcome in the sample space = 1/16
The probability of getting a sum of 5 = 1/4
Step-by-step explanation:
We have been given a four-sided die is a pyramid whose four faces are labeled with the numbers 1, 2, 3 and 4
sample space = {(1,1), (1,2), (1,3), (1,4), (2,1),(2,2), (2,3), (2,4),(3,1), (3,2), (3,3), (3,4), (4,1), (4,2), (4,3), (4,4)}
Two fair 4-sided dices are rolled and all sixteen possible outcomes are equally likely.
The possible outcomes can be deduced by making combinations of different faces with a particular face.
given that each of the outcomes in the sample space is equally likely. So the probability of each outcome in the sample space is the same.
now we find the probability of each of the outcomes in the sample space
(a) when two dices are rolled, we have n(s) = 4*4=16
the chances of getting the outcome as (1,1) n(a) = 1
the probability of getting the outcome as (1,1) p(a)= n(a)/n(b)
p(a) = 1/16
so the probability of each outcome in the sample space = 1/16
(b) P(A) is the probability of getting 5 as a sum
P(A) = Total outcomes with 5 as a sum/Total outcomes
Total outcomes with 5 as sum= 4
Total outcomes= 16
P(A)=4/16=1/4

A) Write an equation that models the amount of storage as a function of the number of songs
B) Interpret the slope and t-intercept of the line of fit
pls include work
a) An equation that models the amount of storage as a function of the number of songs is y = -0.005x + 16
b) Slope of the equation is -0.005 and the intercept of the equation is 16
Slope intercept form
Slope intercept form presents the graph of a straight line and is represented in the form of
y = mx + c.
where
y = y coordinate
m = slope
x = x coordinate
b = y intercept
Given,
Here we have the table shows the amount of storage y (in gigabytes) on a music-playing device when there are x songs on the device
Now, we have to find the following:
a) Equation of the table
b) Slope and intercept.
In order to find the equation, we have to identify the slope an intercept of the table.
So, to find that we have to take two points from the table.
Then the selected points are
(0, 16), (242, 14.8)
By using these point we have to calculate the slope as,
m = (14.8 - 16) / (242 - 0)
m = -1.2/242
m = -0.005
Now, the intercept is calculated by using the point (0, 16) and the slope -0.005, then we get,
16 = -0.005(0) + c
c = 16
Therefore, the equation is y = -0.005x + 16.

The average of the certain set of data can be calculated by dividing the sum of the given numbers/data by their count.
(a) In this item, we are given with: -0.05, 0.09, -0.04, -0.08
Their sum is as follows:
S = (-0.0.5) + (0.09) + (-0.04) + (-0.08)
S = -0.08
Then, divide the sum by 4.
M = -0.08 / 4 = -0.02
b. The answer to this question can be calculated through the equation below,
M₂ = (S + F) / 5
Substituting the known values,
-0.01 = (-0.08 + F) / 5
the value of F is equal to 0.03.
Answer:
15a: -0.02 15b: 0.03
Step-by-step explanation:
15a.
To find the mean, you need to add the values together and divide by the number of values.
(-0.05+0.09+-0.04+-0.08)/4
Simplify:
(-0.05+0.09-0.04-0.08)/4
(-0.05+0.09-0.12)/4
(0.09-0.05-0.12)/4
(0.04-0.12)/4
-0.08/4
-0.02
15b.
let's say the change for Friday is "x"
insert the numbers and add in -0.08 from earlier:
(-0.08+x)/5=-0.01
rearrange (-0.08+x):
(x-0.08)/5=-0.01
multiply both sides by 5:
x-0.08=-0.05
add 0.08 to both sides:
x=0.03

659-360=299°
299° is the co-terminal angle
270 is the line between the 3rd and 4th quadrant, so this is definitely in the 4th quadrant.
let's just count backwards (CW) from zero degrees till we get to our 299° angle going in the forward (CCW) direction. so 299-360= -61°
the reference angle is 61°

Coordinate rule for the composition is w(-1,-2) → s(-1-1,-2-4) → s(-2,-4) , x(-2,0) → t(-2+0,0+2) → t(-2,2), y(1,2) → u(1+1,2+2) → u(2,4) , z(1,-1) → v(1+3,-1+1) → v(4,0).
Given:
w x y x has vertices w(-1,-2) , x(-2,0), y(1,2) and z(1,-1).
s t u v has vertices s(-2,-4) , t(-2,2) , u(2,4) and v(4,0).
The coordinate rule for transformation is:
w(-1,-2) → s(-1-1,-2-4) → s(-2,-4)
x(-2,0) → t(-2+0,0+2) → t(-2,2)
y(1,2) → u(1+1,2+2) → u(2,4)
z(1,-1) → v(1+3,-1+1) → v(4,0)

What is 19% of 40? ??
Answer: 7.6
Step-by-step explanation:
19÷100×40 which will give you 7.6
the number of cars sold annually by used car salespeople is normally distributed with a standard deviation of 15. a random sample of 430 salespeople was taken and the mean number of cars sold annually was found to be 79. find the 97% confidence interval estimate of the population mean.
At the 97% confidence interval estimate of the population mean is
(80.55, 77.45).
Following are the calculation to the confidence interval :
Given that,
σ = 15
n = 430
X = 79
Here C = 97% = 0.97
⇒ α = 1 -C = 1 - 0.97 = 0.03
∴ Zₙ = Zₙ/2 = Z₀.₀₁₅ = 2.17
Now,
97% confidence interval,
C.I = X ± σ/√n
= 79 ± 2.17 × (15/√430)
= 79 + 2.17 × (15/ 21) [taking round figure of √430=2.0736441]
= 80.55
Now taking the negative sign,
= 79 - 2.17 × (15/√430)
= 79 - 2.17 × (15/ 21)
= 77.45
The final answer is (80.55, 77.45).
