Circle C is inscribed in triangle QSU. Circle C is inscribed in triangle Q S U. Points R, T, and V of the circle are on the sides of the triangle. Point R is on side Q S, point T is on side S U, and point V is on side Q U. The length of Q R is 10, the length of R S is 2 x, the length of S T is x + 3, and the length of T U is 4. What is the perimeter of triangle QSU? 3 units 16 units 30 units 40 units
Answer:
I can confirm the answer is:
D. 40 units
Step-by-step explanation:
I just took the test on edge and got it right!
The perimeter of the Δ QSU is given as 40 units. (Option D). See explanation below.
What is the perimeter of Δ QSU?We can derive the perimeter by stating:
2x = x + 3 ⇒ x = 3
This is because Δ RSC ≅ Δ TSC
RS = 2 x 3 = 6 = ST
This is because ΔQRC ≅ ΔQVC
TV = VU = 4; we know this because
ΔCVU ≅ Δ CTU
Thus
QR = QV = 10
CΔQSU = 10 + 6 + 10 +14
= 40 Units.

The Marauders foosball team is improving with each game. The first game they scored no points, but the second game they scored some goals. In their third game they scored 8 more points than the second. Now in their last game they scored three times as many points as their third. Altogether they scored 117 points!!! How many points did the Marauders score in the third game?
Answer:
25 points.
Step-by-step explanation:
In the second game, you can say the Foosball team scored x points.
In their third game, they would have scored x points, plus 8.
In the last game, they would have scored x points, plus 8, then multiply the WHOLE THING by 3.
We would get the following equation...
x + (x + 8) + 3(x + 8) = 117
x + x + 3x + 8 + 24 = 117
5x + 32 = 117
5x = 85
x = 17
So, the Marauders scored 0 points in the first game. In the second game, they scored 17 points. In the third, they scored 17 + 8 = 25 points. In the last, they scored 25 * 3 = 75 points. Altogether, that's 117 points!!

Answer:
8
Step-by-step explanation:
The probability of picking out a certain colour = 12/48 = 1/4
So, this means that every 4 socks you pick out you can be sure of having one of each colour. If you need to find a pair, then you pick out 8.

What is the equation, in slope-intercept form, of the line that is perpendicular to the line
y-4=‐2/3(x-6) and passes through the point (-2, -2)?
y=-x-10
y=-2x19
y=x-1
y=x+1
Answer:
y=3/2x+1
Step-by-step explanation:
y-4= -⅔(x-6)
y-4=-⅔x+4
y=-⅔x+4+4
(equation of line 1) y= -⅔x+8 gradient= -⅔
(line 2)gradient=3/2
note* the gradients of perpendicular lines multiplied result to -1
gradient=y²-y²
x²-x¹
3 =y+2
2. x+2
multiply both sides by 2(x+2)to remove the denominators
3(x+2)=2(y+2)
3x+6=2y+4
3x+6-4=2y
3x+2=2y
divide all sides by 2
3/2x+1=y
y=3/2x+1
what point lies on y-2=5(x-6)
Answer: (0, -28)
Step-by-step explanation:
Turn this equation into slope-intercept form.
y-2=5x-30
y=5x-28.
Because the y-intercept is -28, the point (0,-28) must be on the line.

24 athletes threw the shot put at a track and field meet. If this was 15/100 of all the athletes in the meet, how many athletes competed in the meet total?
Answer:
160 athletes
Step-by-step explanation:
Let the total number of athletes in the meet be x
Given that 24 athletes who threw the shot put at a track and field meet are 15/100 of all the athletes in the meet .
If we write this in mathematical algebraic expression
15/100 of all the athletes in the meet = 24
15/100 * x = 24
=> x = 24*100/15 = 24*100/3*5 = 160
Thus, 160 athletes competed in the meet.

ILL MARK BRAINLIEST In independent random samples of 10 men and 10 women in a coed basketball league, the numbers of points scored per season are given by the back-to-back stemplot below:
Part A: Describe the shape of each data set.
Part B: Michaela analyzed the data and stated that the better measure of center for the women is the mean. Is Michaela correct? Explain your reasoning.
Part C: Michaela decided there are no outliers in the women's data set. Is she correct? Justify your answer mathematically.
Answer:
Step-by-step explanation:
Hello!
a)
To compare both datasets I've made a box plot for them.
The yellow one belongs to the points scored by the men and the green one is for the points scored by the women.
Women: The box seems symmetrical, the median and the mean (black square) are almost the same. The whiskers are almost the same length, you could say that in general the points scored by the women have a symmetrical distribution.
Men: The box looks a little skewed to the right, the median is closer to the 1st quantile and the mean is greater than the median. The whiskers are the same length, in general the distribution seems almost symmetrical.
b)
As you can see in the box plot the median and mean of the points scored by the women are almost the same. Using the data I've calculated both values:
Me= 24.50
X[bar]= 23.80
The median divides the sample in halves (50-50), it shows you where the middle of the distribution is.
The average shows you the value that centers the distribution, meaning, it is the value around which you'll find most of the data set. It summarizes best the sample information and therefore is a better measure of center.
c.
As you can see in the box plots, there are no outliers in both distributions.
An outlier is an observation that is significantly distant from the rest of the data set. They usually represent experimental errors (such as a measurement) or atypical observations. Some statistical measurements, such as the sample mean, are severely affected by this type of values and their presence tends to cause misleading results on a statistical analysis.
Considering the 1st quartile (Q₁), the 3rd quartile (Q₃) and the interquartile range IQR, any value X is considered an outlier if:
X < Q₁ - 1.5 IQR
X > Q₃ + 1.5 IQR
Or extreme outliers if:
X < Q₁ - 3 IQR
X > Q₃ + 3 IQR
For the women data set:
Q₁= 17; Q₃= 30; IQR= 30 - 17= 13
Lower outliers: X < Q₁ - 1.5 IQR= 17-1.5*13= -2.5 ⇒ The minimum value recorded is 03, so there are no outliers.
Upper outliers: X > Q₃ + 3 IQR= 30 + 1.5*13= 49.5 ⇒ The maximum value registered is 41, so there are no outliers.

15. An electric can opener is worth 38 dollars when it is new. After each year it is worth half what it was the
previous year. What will its worth be after 4 years? Round your answer to the nearest cent.
$4.19
$4.75
b. $1.19
d. $2.38
a.
c.
Answer: d. $2.38
Step-by-step explanation:
Exponential decay function: [tex]Ab^x[/tex], where A = initial value
x= Time mperiod
b = multiplicative decay rate
As per given, we have
A = 38 dollars
b= 0.5
Amount after x years : [tex]38(0.5)^x[/tex]
Then, at x= 4
Amount after 4 years : [tex]38(0.5)^4=38(0.0625)[/tex]
[tex]=2.375\approx2.38[/tex]
Hence, the worth of electric can opener after 4 years = $2.38.
So, correct option is d. $2.38
Trevor drew lines of best fit for two scatter plots, as shown. Which statement describes the placement of the lines Trevor drew?
Answer:
A)Only Line A is well placed line of best fit
Step-by-step explanation:
Best fit line :A line through a scatter plot of data points that best expresses the relationship between those points is called best fit line
The least-squares method provides the closest relationship between the dependent and independent variables by minimizing the distance between the residuals and the line of best fit
By considering both the given graphs
We can see that Line A gives the minimum distance between residuals and line of best fit whereas Line B does not give the minimum distance between residuals and line of best fit
So,Option A is true
A)Only Line A is well placed line of best fit
Answer: a) only line A is a well placed line of best fit

The population of a large city can be calculated using the function . What can you say about the rate of change from year 1 to year 2 compared to the rate of change from year 9 to year 10
Answer:
The rate of change will be the same for all years.
Step-by-step explanation:
As it is mentioned in the question, that the rate of change is 7%.
And as we know that
= I (1 + R)^T
where
I = Initial amount
R = Rate of growth,
And T = Time.
So in the given case, the rate is 0.07, or 7% while on the other hand the growth RATE remains constant and the growing amount would be increased each year.
Therefore the rate of change would be the same for all the year

Hello, a Maths question if anyone knows what to do Solve: 6(x+4)=30
Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
Step-by-step explanation: 6(x+4)=30
(Distributive property): 6x+24=30
( Transposition method): 6x=30-24( + becomes -) 6x=6
(Transpose 6 to rhs) x=6/6( since it was multiplication on LHS it becomes division in RHS) x=1

Rectangle A has a width of 3 inches and a length of 5 inches. Part A Rectangle A has the same perimeter as Rectangle B. If its width is 4 inches, what is its length? Enter your answer in the box. Rectangle B has a width of 4 inches and a length of inches
Answer:
Rectangle B has a length of 4 inches.
Step-by-step explanation:
Rectangle A has a width of 3 inches and a length of 5 inches.
Let us find its perimeter:
Perimeter = 2(L + W)
where L = length
W = width
Its perimeter is therefore:
P = 2(5 + 3)
P = 2 * 8 = 16 inches
Rectangle B has the same perimeter as Rectangle A. Let us find the length of B.
Its width is 4 inches, therefore, perimeter is:
P = 2(L + W)
16 = 2(L + 4)
16 = 2L + 8
16 - 8 = 2L
8 = 2L
=> L = 8 / 2 = 4 inches
Rectangle B has a length of 4 inches.
