In the remaining part of the semester, Zachery wrote an average of 10,000 words per month to complete his final project for the course.

We are given that Zachery has to write a total of 95,234 words.

Total words to be written = 95,234 words.

Words already written in the first month = 35,295 words.

Words already written in the second month = 19,240 words.

Words written in total = 35,295 words + 19,240 words.

= 54,535 words

Words left for writing = 95,234 words - 54,535 words

= 39,699 words

months left = 4

Average Words written in remaining month = 39,699 words / 4

= 9924.75 words.

= 10,000 words.

Therefore, in the remaining part of the semester, Zachery wrote an average of 10,000 words per month to complete his final project for the course.

The slope of the line that is parallel to the given equation is 4

From the question, we are to determine the slope of the equation that is parallel to the given line

The given line is

y = 4x + 4

First, we will determine the slope of the given line

By comparing with the slope-intercept form of the equation of a straight line,

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison,

m = 4

Thus,

The slope of the line is 4

NOTE: If two lines are parallel, their slopes are equal

Hence, the slope is 4

The percentage of batteries that last between 1.25 and 5.75 years will be 99.73%.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

One significant manufacturer's batteries are known to have a shelf life that is regularly distributed, with an average life of 3.5 years and a standard deviation of 0.75 years.

The value of the z-score will be

z = (1.25 - 3.5) / 0.75, (5.75 - 3.5) / 0.75

z = -3, 3

The percentage of batteries that last between 1.25 and 5.75 years will be

P(1.25 < x < 5.75) = P(- 3 < z < 3) x 100

P(1.25 < x < 5.75) = 0.9973 x 100

P(1.25 < x < 5.75) = 99.73%

The percentage of batteries that last between 1.25 and 5.75 years will be 99.73%.

The function that represents the difference, h(x) = f(x) – g(x), between the value of Aleka’s and Helene’s total savings after x years is C. h(x) = 1000(1.025)x – 200x.

It should be noted that Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account.

The function for Aleka will be:

= 2500 (1.025)^x

The function for Helene will be:

= 1500(1./25)^x + 200x

Therefore, the difference of the function will be 1000(1.025)x – 200x.

The length of rectangular room is 9.5 meter.

The width of rectangular room is 5 meter.

What is Perimeter of rectangular?

The perimeter of a rectangle is two time the sum of length and width of rectangle.

Given that;

The perimeter of rectangular room = 29 meter

The length of rectangular room is 1.9 times as long as it is wide.

Now, Let the width of rectangular room = x

Then Length of rectangular room = 1.9x

Since, Perimeter of rectangular room = 2 ( length + width)

⇒ 29 =  2 (1.9x + x)

⇒ 29 = 2 * 2.9x

⇒ x = 5

Hence, The length of rectangular room = 1.9x

                                                             = 1.9 * 5

                                                             = 9.5 meter

The width of rectangular room is = x

                                                    = 5 meter.

So, The length of rectangular room is 9.5 meter.

The width of rectangular room is 5 meter.

Answer: Dana estimation is incorrect because difference = 598 miles

Step-by-step explanation:

Given data,

Dana has driven her car 95,598 miles.

She estimates she can

drive the car another 5000 miles.

she can,

drive the car another 5000 miles before the mileage reaches

100,000 miles.

Estimated Mileage of the car is equal to 100,000 miles.

That is,        

Estimated  Mileage of the car is = 100,000 miles.

So,

We can write,

Total distance Dana has to travel = already driven + additional miles to cover

Total distance Dana has to travel = 95,598 + 5,000 miles

Total distance Dana has to travel = 1,00,598 miles.  

As per mileage of car is  100,000 miles.

So, Dana has to travel = 1,00,598 miles.  

So, Dana estimation is incorrect because difference is = 100,598 - 100,000

Therefore,  

Dana estimation is incorrect because difference = 598 miles

If the height and volume of the prism are 6 inches and 30 cubic inches. Then the base area of the prism is 5 square inches.

What is a rectangular prism?

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.

The volume of a right rectangular prism is found by multiplying the length of the base by the width of the base by the height of the prism.

A right rectangular prism has a volume of 30 cubic inches.

If the height of the prism is 6 inches. Then the base area of the prism will be

The volume is given as

Volume = Base area × Height

We know

Volume = 30

Height = 6

Then the base area will be

  30 = Area × 6

Area = 5

The amount he put into the first account at 2% interest will be $8,000 and into the second account at 7% interest will be $42,000.

Given that,

Amount invested by Alex = $50,000,

Total interest earned = 6.2%,

Now,

Let,

Amount invested at 2% = x,

So,

Amount invested at 7% = (50,000 - x),

So,

According to the question,

7%(50000 - x) + 2%(x) = 6.2% * 50,000

we get,

0.07(50000 - x) + 0.02(x) = 0.062 * 50,000

3500 - 0.07x + 0.02x = 3100

3500 - 0.05x = 3100

We  get,

0.05x = 3500 - 3100

0.05x = 400

x = 8000,

So,

Amount invested at 2% = $8000,

So,

Amount invested at 7% = (50,000 - 8000) = $42,000,

Hence we can say that the amount he put into the first account at 2% interest will be $8,000 and into the second account at 7% interest will be $42,000.

Answer:

  (c)  -19 + x = -21

Step-by-step explanation:

You want the mathematical expression equivalent to the English sentence "a number added to -19 is -21."

Addition is written using the math plus symbol (+).

The English word "is" usually signifies sameness or equality, expressed using the math equal sign (=).

The variable x is often used to represent "a number."

When a number is added to -19, we start with -19, then, using the plus symbol, we add x:

  "a number added to -19"   ⇒   -19 + x

  "is"   ⇒   =

   "-21"   ⇒   -21

So, the translated description is ...

  -19 + x = -21

The value of the account is $47226.73.

The compound interest formula is equal to  

A = P( 1 + r/n )^{nt}

where  A is the Final Investment Value, P is the Principal amount of money that is to be invested, r is the rate of interest, t is the Number of Time Periods, and n is the number of times interest is compounded per year.

Now, we have:

t = 21 years

Principal amount, P = $9000

Rate, r = 8% = 0.08 and

n = 12 as a year has 12 months.

Substituting these values in the formula,

[tex]A = P( 1 + \frac{r}{n} )^{nt}[/tex]

A = 9000 × ( 1 + 0.08/12)²⁵²

A = 9000 × ( 1 + 0.0066)²⁵²

A = 9000 × ( 1.0066)²⁵²

A = 9000 × 5.247

A = 47226.73

The value of the account will be $47226.73.
