Answer:

To calculate the total amount, first find out how much you contribute and then add the amount your employer contributes.

Your contribution: 10% of $50,000

= ($50,000 * 10) / 100

= $5,000

Employer's contribution: 3% of $50,000

= ($50,000 * 3) / 100

= $1,500

Total contribution:

= Your contribution + Employer's contribution

= $5,000 + $1,500

= $6,500

So, the total amount being put away in your account each year is $6,500.

Step-by-step explanation: Make a perfect square list

This is one that goes to 15

\(\sqrt{1} \sqrt{4} \sqrt{9} \sqrt{16} \sqrt{25} \sqrt{36} \sqrt{49} \sqrt{64} \sqrt{81} \sqrt{100} \sqrt{121} \sqrt{144} \sqrt{169} \sqrt{196} \sqrt{225}\)

1      2  3    4    5    6     7    8    9     10    11     12    13     14    15

The numbers on top are the square root and the numbers under are the answer or squared numbers. There is also a way to solve them if the number is between a number in the list like 18 but i don't feel like explaining that this is just the basic squares.

Answer:

\(y=\frac{1}{3}x\)

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: \(y=mx+b\) where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

1) Determine the slope (m)

\(m=\frac{y_2-y_1}{x_2-x_1}\) where two points the line passes through are \((x_1,y_1)\) and \((x_2,y_2)\)

Plug in the given points (-3,-1) and (6,2)

\(=\frac{2-(-1)}{6-(-3)}\\=\frac{2+1}{6+3}\\=\frac{3}{9}\\=\frac{1}{3}\)

Therefore, the slope of the line is \(\frac{1}{3}\). Plug this into \(y=mx+b\):

\(y=\frac{1}{3}x+b\)

2) Determine the y-intercept (b)

\(y=\frac{1}{3}x+b\)

Plug in one of the given points and solve for b

\(2=\frac{1}{3}(6)+b\\2=2+b\)

Subtract 2 from both sides to isolate b

\(2-2=2+b-2\\0=b\)

Therefore, the y-intercept is equal to 0. Plug this back into \(y=\frac{1}{3}x+b\):

\(y=\frac{1}{3}x+0\\y=\frac{1}{3}x\)

I hope this helps!

Answer:

40% and 196

Step-by-step explanation:

The computation of the number of people visit the museum on wednesday is shown below:

Given that

On monday, the visitors are 100

And, on tuesday, the visitors are 140

Now the percentage change would be

= (140 - 100) ÷ (100) × 100

= 40%

Now the visitors as on wednesday is

= 140 + 140 × 0.40

= 140 + 56

= 196

Answer:

y=2x-8

Step-by-step explanation:

y=Mx+k

Plug in(3,-2)(6,4)

3m+k=-2

6m+k=4

First function multiply by 2,we got:

6m+2k=-4

6m+k=4

k=-8

Y=Mx-8

Plug in any points that is in the question, I use(6,4)

4=6m-8

m=2

Y=2x-8

Answer:

y = 2x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (3, - 2) and (x₂, y₂ ) = (6, 4)

m = \(\frac{4+2}{6-3}\) = \(\frac{6}{3}\) = 2, then

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (6, 4 ), then

4 = 12 + c ⇒ c = 4 - 12 = - 8

y = 2x - 8 ← equation of line

Francisco made the following mistake while finding the equation of the perpendicular line, writing 4 instead of - 4 on step 2.

In this problem we must determine what step was mistaken by Francisco on determining the equation of the perpendicular line. Any line can be found by knowing a point and the slope of a line:

y - y₁ = m · (x - x₁)

Where:

And the slope can be determined by knowing the coordinates of two distinct points on line:

m = Δy / Δx

And the relationship between two lines that perpendicular to each other:

m · m' = - 1

Where m' is the slope of the perpendicular line.

Now we proceed to show the complete steps:

Step 1: m =  1 / 4

Step 2: m' = - 4 (Mistake found)

Step 3: y - y₁ = m · (x - x₁), Q(x, y) = (6, - 2)

            y + 2 = - 4 · (x - 6)

Step 4: y + 2 = - 4 · x + 24

Step 5: y + 2 - 2 = - 4 · x + 24 - 2

Step 6: y = - 4 · x + 22

5 feet is the greatest distance that a person could be from the lamp and be detected.

A circle is defined as round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).

Since we have given that

The equation is :

\((x+15)^2+(y-12)^2=25\)

It is the equation of circle in which center is (h,k) i.e. ( 15,12)

The general equation of circle is given by

\((x-h)^2+(y-k)^2=r^2\)

Here, the radius 'r' is given by

\(r^2=25\)

\(r=\sqrt{25\)

\(r=5\)

Here, the greatest distance a person could be from the lamp and be detected is represented by radius i.e. r = 5 feet.

Hence, 5 feet is the greatest distance that a person could be from the lamp and be detected.

100 square centimeters are in the area of the largest possible inscribed triangle having one side as a diameter of circle.

What is the area?

A two-dimensional figure's area is the amount of space it takes up. In other terms, it is the amount that counts the number of unit squares that span a closed figure's surface. In general, square units such as square inches, square feet, etc. are used as the standard unit of area.

Base = 2r = 2*10 = 20 cm

x= -7/2

y= 5/4

Step-by-step explanation:

x-2y=-11

x+2y = -6

then isolate x and set equal to each other

-2y - 6 = 2y -11

4y = 5

y = 5/4

then solve for x using y.

x+5/2 = -6

x = -7/2

Answer:

x = -4

Step-by-step explanation:

Step 1: Define

j(x) = 3x + 1

j(x) = -11

Step 2: Substitute and solve for x

After 37 bounces, the ball's height will be less than 1 foot.

The initial height of the ball is 50 feet.

After first bounce, the ball will reach a height of:

= 50 feet * (1 - 10%)

= 45 feet.

After second bounce, it will reach a height of:

= 45 feet * (1 - 10%)

= 40.5 feet.

Height decreases by 10% after each bounce.

We have to set up an equation:

50 feet * (0.9)^n < 1 foot

Simplifying:

0.9^n < 1/50

Taking the logarithm:

n * log(0.9) < log(1/50)

n > log(1/50) / log(0.9)

n > 37.1298771746

Answer:

Below.

Step-by-step explanation:

The total number of marbles is 12.

Part A.

Prob(Red marble) = 5/12.

Part B.

Prob(pick 3 red marbles without replacement) = 5/12 * 4/11 * 3/10 = 1/22.

Part C.

The probability of the first being red is 5/12 because there are 5 red out of a total of 12 marbles. After that there are only 4 marbles and the total is 11 ( 1 marble less). Finally on the 3rd pick there are 3 red and a total of 10. WE then multiply these 3 probabilities.

Answer:

Chicago

Step-by-step explanation:

Compare the temperatures:

-4, -14, -11, -13

Numbers become smaller to the left on the number scale.
For instance, -10 is less than -5.

So, -13, -11, and -4 are all greater than -14.

And the lower the temperature, the colder it is.

Thus, Chicago is the coldest.

Answer: -1.4h + 8

Step-by-step explanation:

     To write an equivalent expression, we will combine all like terms. This means we will add, subtract, divide, or multiply all terms that have the same variable and power.

     Given:

h + 5 + 3 - 2.4h

     Rearrange so like terms are next to each other:

5 + 3 - 2.4h + h

     Combine like terms:

We can use a two-way ANOVA to compare the means of the three coefficients for OECD and non-OECD countries and assess whether the differences are probability significant.

To test the hypothesis that the three coefficients in the population regression are equal for OECD and non-OECD countries, we can run a two-way ANOVA. The two factors in this ANOVA would be OECD status (OECD or non-OECD) and the three coefficients in the population regression (income, population density, and urbanization). This will enable us to compare the means of the three coefficients for OECD and non-OECD countries and assess whether the differences are statistically significant. We can also use the F-statistic to see if the differences between the means of the two groups are statistically significant. This will allow us to assess whether the coefficients in the population regression are indeed different for OECD and non-OECD countries.
