You accept a job with a salary of $37,300. After 6 months, you receive a 6% raise. What is your new salary?
Answer:
If you accept a job with a salary of $37,300 and receive a 6% raise after 6 months, your new salary will be $37,300 x 6/100 = $2,238. This is the amount of your raise. To determine your new salary, we can add the raise to your original salary, which gives us:
New salary = $37,300 + $2,238 = $39,538
Therefore, your new salary after receiving a 6% raise will be $39,538.

The simplified value of the given fractions is -11/12
What does division of fractions mean?
A fraction is divided into additional equal pieces when it is divided into fractions. For instance, if you had three-fourths of a pizza remaining and divided each slice into two pieces, you would have received six slices, which would be equivalent to six-eighths of the entire pizza.
Top expression = 5/8 + 3/4
= (5 + 6)/ 8 = 11/8 ( 8 is the lcm of 4 and 8 )
Bottom expression = -2/3 - 5/6
= (-4 - 5)/ 6
= -9/6 = -3/2
Top expression/ Bottom expression = (11/8)/ (-3/2 )
= - (11/8) * (2/3)
= -11/12

To reject the null hypothesis of equal coefficients in the global test from the output tables of a multiple regression model, F- distribution is used
What is F- distribution?
F- distribution is the used to test if the two observed sample has the same variance or not.
F- distribution is used to reject the null hypothesis when the two samples have the same variance.
Here, the null hypothesis of equal coefficients has to be rejected in a global test.

Step-by-step explanation:
This might be the correct answer if I'm not mistaken:
Extending the right side of the bottom triangle leads to m<1 and 120 vertical angles.
You use the Vertical Angles Theorem, and figure that 120 is congruent to m<1. Thus, i think 120 degrees is the answer.
If sin B = − 1/3 with B in QIII, find the following.
cos B/2
Answer:
In the third quadrant, the sine of an angle is negative, so the angle itself must be between 180 and 270 degrees. This means that the cosine of the angle, and therefore the cosine of half the angle, is also negative.
To find the exact value of the cosine of half the angle, we can use the double angle formula for cosine, which states that cos(2A) = 1 - 2sin^2(A). Since the sine of half the angle is sin(B/2) = sqrt((1 - cos(B))/2), we can plug this into the double angle formula to get:
cos(B/2) = sqrt(1 - cos(B))/sqrt(2) = sqrt((1 - (-1/3))/2) = sqrt(4/6)/sqrt(2) = sqrt(2/3)/sqrt(2) = sqrt(1/3)
Therefore, the value of cos(B/2) is sqrt(1/3), which is positive because B/2 is between 0 and 90 degrees. The exact value of the cosine of half the angle B in the third quadrant is sqrt(1/3).

Jump up! Refer to Exercise 6. Suppose that the corrected long-jump distances are converted from centimeters to meters (note that 100 cm = 1 m). (a) What shape would the resulting distribution have? Explain your answer. (b) Find the mean of the distribution of corrected long-jump distance in meters. (c) Find the standard deviation of the distribution of corrected long-jump distance in meters.
Shape would the resulting distribution have very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.
Define symmetry.In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. A more exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling.
Given,
100 cm = 1 m
Xₙ = 557.3 cm
Divide each centimeter number by 100 to convert the corrected long jump distances from centimeters to meters.
A very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.
The distribution's structure is unaltered when each value in the data is divided by 100 since there are no changes to the relationships between any two pieces of data.
Since there is just one peak in this example, the corrected long-jump distances in meters distribution likewise has an almost symmetric form.

What percent is 10 out of 25 SHOW WORK
Answer:
To find the percent of a number, we need to divide the number by the total and then multiply by 100%. In this case, we want to find the percent of 10 out of 25, so we need to divide 10 by 25 and then multiply by 100%. This gives us 10/25 * 100% = 40%. Therefore, 10 out of 25 is equal to 40%.

P(t)=
(b) What will be the population after 8 hours?
bacteria
(c) How long will it take for the population to reach 2450? Give your answer accurate to at least 2 decimal places.

A) The population P after t hours as a function of t p(t) = 820 [tex]e^{0.3465t}[/tex] k = 0.3465 , B)The population after 8 hours of
bacteria is p(8) = 13120 , C) The population to reach 2450, time will be t= 3.15 hour
What is proportional?A linear relationship between two amounts or variables is shown by proportionality. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original amount.
It is given that
dp/dt ∝ p
dp/dt = kp
dp/p = kdt
log p = kt +c
p(t) = c[tex]e^{kt}[/tex]
when t = 0 then p = 820
therefore c = 820
p(t) = c[tex]e^{kt}[/tex]
when t = 2hours then p = 1640
1640 = 820[tex]e^{2k}[/tex]
2k = ln2
k = ln2/2
k = 0.3465
p(t) = 820[tex]e^{0.3465t}[/tex] bacteria
B)
when t = 8hours
p(8) = 820[tex]e^{0.3465* 8}[/tex]
p(8)= 820*16
p(8) = 13120 bacteria
c)
when p = 2450 then t = ?
2450 = 820[tex]e^{0.3465t}[/tex]
2450/820 = [tex]e^{0.3465t}[/tex]
t =1.0945/0.3465
t= 3.15hours
Thus
A) The population P after t hours as a function of t p(t) = 820 [tex]e^{0.3465t}[/tex] k = 0.3465 , B)The population after 8 hours of

Answer:
3. y int= 6
4. m=6
5. y=-2x-8
Step-by-step explanation:
3. since the y intercept is when x=0 the table shows the y=6.
4. to find m we use change in y/change in x
the change in y is 6 because 6-0=6
change is x is 1 because 0--1=1
6/1=6
5. y=mx+c
c is y intercept thus c= -8
m is function rate/ gradient of the line = -2
this is because:
change in y= -8--2=-6
change in x= 0--3=3
-6/3= -2
thus y=-2x-8

What is the equation of the line that passes through the point (8, 3) and has a slope
of -1?
Answer:
y = -x + 11
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept so m = -1
y = -x + b
Now substitute x = 8 and y = 3:
3 = -8 + b
b = 11
Thus the final equation is y = -x + 11.

What is meant by trigonometric identities?Trigonometry is the study of angles and the angular connections between figures in two and three dimensions. The trigonometric functions that make up trigonometry are cosecant, cosine, cotangent, secant, sine, and tangent. These are also known as the circle functions.
Trigonometric Identities are equality statements involving trigonometry functions that hold true for all values of the input variables in the equation. The side length and angle of a triangle are both subject to a variety of distinctive trigonometric identities.
The triangle is right angled, therefore we can apply trigonometry :
To obtain the value of X which is the hypotenuse :
Using trigonometric identities,
Cosθ = adjacent / hypotenuse
Substitute the values in the above equation, we get
Cos 30 = 11 / X
√3/2 = 11 / X
simplifying the above equation, we get
√3 / 2 × X = 11
X = 11 ÷ √3 / 2
X = 11 × 2 / √3
X = 22/√3
Therefore, the length of side X in the simplest radical form is 22/√3.
