Answer:
x = 50° y = 130°
Step-by-step explanation:
x and 50° are vertically opposite angles and are congruent , then
x = 50°
y and 50° are adjacent angles and sum to 180° , then
y + 50° = 180° ( subtract 50° from both sides )
y = 130°

Find the mean, median, and mode of the data set 67, 52, 50, 99, 66, 50, and 57 with and without the outlier. which measure does the outlier affect the most?
Answers
Answer:
Mean - 63
Median - 57
The Mean affects the outlier the most.
Step-by-step explanation:
Mean is where u add all the numbers up and then divide them by how many are there. So 50 + 50 + 52 + 57 + 66 + 67 + 99 = 441. There are 7 numbers so 441/7 which equals 63. So mean is 63.
For median u order them least to greatest which is 50,50,52,57,66,67,99. The median is the middle number of this set which is 57.
Outlier is the first number which is 50. So the mean is the answer for which measure does the outlier affect the most bc 63 is bigger than 57 the median. So basically which is a more difference.
Eric and Linda are paid 52.25 for they're work. Eric worked 3.5 hours, and Linda worked 2 hours. They split the money according to the amount of time they worked. How much is Erics share of the money?
Answers
Answer:
$33.25
Step-by-step explanation:
Taking Eric's hours as a ratio to the total hours :
3.5 : 3.5 + 23.5 : 5.53.5 x 2 = : 5.5 x 27 : 11Multiply the ratio into the amount paid :
52.25 x 7/114.75 x 7$33.25Eric's share of the money is $33.25
Answer:
$33.25
Step-by-step explanation:
The combined, total number of hours they worked is
3.5 hours + 2 hours = 5.5 hours
The total pay is $52.25
The pay rate is $52.25/(5.5 hours) = $9.50/hour
Eric worked 3.5 hours.
Pay = 3.5 hours × $9.50/hour = $33.25

have a down payment of $4,000 on a car that costs $19,500.
Calculate her monthly payments for a 5-year loan.
Answers
Answer:
$273.38 per month
Step-by-step explanation:
Monthly Payment Formula
[tex]\sf PMT=\dfrac{Pi(1+i)^n}{(1+i)^n-1}[/tex]
where:
PMT = monthly paymentP = loan amounti = interest rate per month (in decimal form)n = term of the loan (in months)Given:
P = $19,500 - $4,000 = $15,500i = 2.25% / 12 = 0.0225 / 12n = 5 years = 60 months[tex]\implies \sf PMT=\dfrac{15500 (\frac{0.0225}{12})(1+\frac{0.0225}{12})^{60}}{(1+\frac{0.0225}{12})^{60}-1}[/tex]

Answer:
f(x) ≈ −2.42x3 + 15.89x2 − 7.55x + 12
Step-by-step explanation:
Notice that the year data are evenly spaced. Check the first differences between the total number or units to see if the data set is linear.
First Differences
41 − 18 = 23
67 − 41 = 26
82 − 67 = 15
69 − 82 = −13
17 − 69 = −52
Because the first differences are not constant, a linear model is not the best model of the data. Check the second differences to see if the data set can be modeled by a quadratic function.
Second Differences
26 − 23 = 3
15 − 26 = −11
−13 − 15 = −28
−52 − (−13) = −39
Because the second differences of the independent variable are not constant, a quadratic model is not the best model of the data. Check the third differences to see if the data set can be modeled by a cubic function.
Third Differences
−11 − 3 = −14
−28 − (−11) = −17
−39 − (−28) = −11
The third differences are approximately the same so we will use a cubic function to represent the data.
Enter the data into a calculator. Plot the data and find the cubic regression equation that best models the data.

Step-by-step explanation:
If you add all of the numbers, you get 32. When you divide it by how many numbers there were, you get 4. When you add 4 to 32, you get 36 and since you added one more number, you need to divide 36 by 9, which still makes 4.

Alpha particles are accelerated in a cyclotron to a final orbit radius of 0. 50 m. The magnetic field in the cyclotron is 0. 90 t. The period of the circular motion of the alpha particles is closest to 0.11μs.
How do find the time period in a cyclotron?The period of the circular motion of the alpha particles moving along an in the presence of the magnetic field is given by;
[tex]T = \dfrac{2\pi m}{qB}[/tex]
Alpha particles are accelerated in a cyclotron to a final orbit radius of 0. 50 m. The magnetic field in the cyclotron is 0. 90 t.
We are given;
Mass; m = 6.68 × 10^(-27) kg
Magnetic field;B = 0.90 T
Charge;q = 2e
Now, e is the charge on an electron and it has a value of 1.6 × 10^(-19) C
So, q = 2 × 1.6 × 10^(-19)
q = 3.2 × 10^(-19) C
we know that,
[tex]T = \dfrac{2\pi m}{qB}[/tex]
we have;

The probability of calling a person, not from his neighborhood, is 1/5 or 0.2 if the total number of contacts is 25
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of contacts = 25
Total number of contacts of neighbors = 20
Total number of contacts which is not of the neighbors = 25 - 20 = 5
The probability of call a person not from his neighborhood:
P = 5/25 = 1/5
P = 0.2
Thus, the probability of calling a person, not from his neighborhood is 1/5 or 0.2 if the total number of contacts is 25

Answers
The surface area of the rectangular box = the amount of wrapping paper needed to cover the rectangular box = 394.24 in.²
What is the Surface Area of a Rectangular Box?Surface area = 2(wl + hl + hw).
Volume = lwh.
Given the following:
Volume = 476.16 in.³
Length = 4.8 in.
Width = 8 in.
Find the height (h) using the volume formula:
476.16 = 4.8 × 8 × h
476.16 = 38.4 × h
476.16/38.4 = h
h = 12.4 in.
Surface area = 2(wl + hl + hw) = 2(8 × 4.8 + 12.4 × 4.8 + 12.4 × 8) = 394.24 in.²
The amount of wrapping paper needed to cover the rectangular box = Surface area = 394.24 in.²
