Answer:
Angle T= 36 degrees
Angle V= 54 degress
Step-by-step explanation:
okay so you know that this is a right angle and that all angles in a triangle add up to 180 degress
using that info,
you can say
2x+3x+90= 180
5x+90=180
5x= 180-90
5x= 90
x= 18
measure of angle T= 2x
2(18)= 36 degrees
measure of angle V= 3x
3(18)= 54 degrees
I hope this helps <3

Answer:
y' = -y/x
Step-by-step explanation:
It looks like you have ...
e^z -z = 0 . . . . . where z = xy
Differentiating with respect to x gives ...
z'·e^z -z' = 0
z'(e^z -1) = 0
The zero-product rule tells you this is true for e^z = 1, which is not useful for finding y', and for z' = 0, which is.
z = xy
z' = y +xy' = 0
y' = -y/x

You can save $200 monthly to put into your retirement account and you have 35 years until you retire. Assume an 8% rate of return and a monthly compounding period.
a. How much money will you have in retirement?
b. What things could you change to increase the amount you will have in retirement?
c. Make just one change (amount, time, or interest rate) and write down how much money you will now have in retirement.
Answers
Answer:
Step-by-step explanation:
Q1 .
Money saved every month = $200
Time period until you retire = 35 years
Rate of Interest = 8%
The money is compounded monthly.
a). Amount for retirement = Saving annuity
Saving or making a series of payments at regular intervals is called annuity.
Annuity formula is :
P_{n} = d((1 + r/k)^{nk} - 1)/(r/k)
PN is the balance in the account after N years.
d is the regular deposit (the amount you deposit each month)
r is the annual interest rate in decimal form(R/100)
k is the number of compounding periods in one year
Here d= $200 , r = 0.08 , n = 35 years , k = 12 (compounded monthly)
P_{n} = 200((1 + 0.08/12)^{(35*12)} - 1)/(0.08/12)
= $ 458776.50
b). Looking at the formula used in above option we can -
Increase number of years to increase retirement amount
Increase the monthly amount deposited
Increasing rate of interest also increases the amount
Compounding Annually , half yearly or quaterly will decrease the amount
c). Let us change the amount from $200 to $300 . Then amount will be
P_{n} = d((1 + r/k)^{nk} - 1)/(r/k)
P_{n} = 300((1 + 0.08/12)^{(35*12)} - 1)/(0.08/12)
= $ 688164.75

A seafood-sales manager collected data on the maximum daily temperature, T, and the daily revenue from salmon sales, R, using sales receipts for 30 days selected at random. Using the data, the manager conducted a regression analysis and found the least-squares regression line to be Rˆ=126+2.37T. A hypothesis test was conducted to investigate whether there is a linear relationship between maximum daily temperature and the daily revenue from salmon sales. The standard error for the slope of the regression line is SEb1=0.65. Assuming the conditions for inference have been met, which of the following is closest to the value of the test statistic for the hypothesis test?
a. t=0.274
b. t=0.65
c. t=1.54
d. t=3.65
e. t=193.85
Answers
Answer: d
Step-by-step explanation:
t= b1- B0/ SE(b1) = 2.37-0/0.65= 3.646 -> 3.65
The closest value of the test statistic for the hypothesis test is 3.65 if the least-squares regression line to be Rˆ=126+2.37T option (d) is correct.
What is a regression line?A regression line is a graph that illustrates the pattern of a group of statistics. In other words, it shows the data's best pattern.
We have a least-squares regression line to be:
R^ = 126+2.37T
A hypothesis test was conducted to investigate whether there is a linear relationship between maximum daily temperature and the daily revenue from salmon sales.
Using a T-test to find the significance of the slope coefficient is measured:
[tex]\rm t = \frac{b}{SE}[/tex]
Here SE = 0.65
b = 2.37
Put this value in the above expression, we get:
[tex]\rm t = \frac{2.37}{0.65}[/tex]
t = 3.6461 or
t = 3.65
Thus, the closest value of the test statistic for the hypothesis test is 3.65 if the least-squares regression line to be Rˆ=126+2.37T option (d) is correct.

find the diameter of circle Q if angle PQR measures 31° and the arc length of PR is 9 cm
Answers
Answer:
33.4 cm
Step-by-step explanation:
Given:
θ = 31°
Arc length of PR = 9 cm
Required:
Diameter
Solution:
Diameter of the circle = 2*radiius = 2*PQl
Arc length = θ/360 × 2πr
Plug in the values into the equation
9 = 31/360 × 2πr
9 = 0.54r
9/0.54 = r
16.6666667 = r
r = 16.7 cm
Radius = 16.7 cm
Therefore,
Diameter = 2*radius = 2*16.7 = 33.4 cm

Step-by-step explanation:
A personal identification number (PIN)
consists of four digits. Consider the
PIN 0005 equal to the number 5, etc. Find
the probability that a PIN number is:
a equal to 0000
b less than 8000 and more than 7900
c divisible by 10
d at least 13.
Answers
Using the probability concept, it is found that there is a:
a) 0.0001 = 0.01% probability that a PIN number is equal to 0000.b) 0.0099 = 0.99% probability that a PIN number is less than 8000 and more than 7900.c) 0.1 = 10% probability that a PIN number is divisible by 10.d) 0.9988 = 99.88% probability that a PIN number is at least 13.What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
A personal identification number (PIN) consists of four digits, and considering they can repeat, the total number of PINs is:
[tex]T = 10^4 = 10000[/tex]
Item a:
A PIN equals to 0000 is one outcome, hence:
[tex]p = \frac{1}{10000} = 0.0001[/tex]
0.0001 = 0.01% probability that a PIN number is equal to 0000.
Item b:
In this interval, there are 8000 - 7900 - 1 = 99 possible values, hence:
[tex]p = \frac{99}{10000} = 0.0099[/tex]
0.0099 = 0.99% probability that a PIN number is less than 8000 and more than 7900.
Item c:
One in ten numbers are divisible by 10, hence:
[tex]p = \frac{1}{10} = 0.1[/tex]
0.1 = 10% probability that a PIN number is divisible by 10.
Item d:
12 numbers, from 1 to 12, are less than 13, hence 10000 - 12 = 9988 are at least 13, hence:
[tex]p = \frac{9988}{10000} = 0.9988[/tex]
0.9988 = 99.88% probability that a PIN number is at least 13.
