What is ( 2 ⅓ * x ) + x?

Answer:

5,477.63

Step-by-step explanation:

First, convert R percent to r a decimal

r = R/100

r = 6%/100

r = 0.06 per year,

Then, solve our equation for P

P = A / (1 + r/n)nt

P = 5,500.00 / (1 + 0.06/4)(4)(0.068448)

P = 5,500.00 / (1 + 0.015)(0.273792)

P = $ 5,477.63

Summary:

The principal investment required to get

a total amount of $ 5,500.00

from compound interest at a rate of 6% per year

compounded 4 times per year

over 0.068448 years

is $ 5,477.63.

Answer:

c maybe i think. tell me if its right

Answer:

Step-by-step explanation:

Use Pythagorean Theorem for a right triangle.

a^2 + b^2 = c^2

3.6^2 + 4.8^2 = c^2

c = 6cm

The length of y (Hypotenuse) is 6 cm.

We have,

Perpendicular = 3.6 cm

Base = 4.8 cm

Hypotenuse = y

Using Pythagoras theorem

Hypotenuse² = Base² + Perpendicular²

So, y² = 4.8² + 3.6²

y²= 23.04+ 12.96

y²=

y= √36

y= 6 cm

Thus, the value of y (Hypotenuse) is 6 cm.

Step-by-step explanation:

From the question we are given the table

[tex]\begin\\\begin{tabular}{|l|l|l|l|l|} &&y \\x &0&1&2&3\\0 &0.13&0.1&0.07&0.03 \\1&0.12&0.16&0.08&0.04\\ 2&0.02&0.06&0.08&0.04\\ 3&0.01&0.02&0.02&0.02\end[/tex]

Generally the marginal probability mass function of X is mathematically given as

[tex]P(x)=\sum P(x,y)>y[/tex]

[tex]\sum P(0)=0.13+0.1+0.07+0.03=0.33\\\sum P(1)=0.12+0.16+0.08+0.04=0.40\\\sum P(2)=0.02+0.06+0.08+0.04=0.20\\\sum P(3)=0.01+0.02+0.02+0.02=0.07[/tex]

Therefore marginal probability mass function of X

Answer:

The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).

Step-by-step explanation:

To find the interval, we can just make the conversion of the values from pounds to kilograms.

Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.

Confidence interval: (102.3 pounds, 106.5 pounds).

102.3 pounds = 102.3/2.2 = 46.5 kilograms

106.5 pounds = 106.5/2.2 = 48.41 kilograms

The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).

Answer:

The 95% confidence interval for the population mean gas price in Gainesville is between $2.54 and $2.62.

Step-by-step explanation:

We have the standard deviation of the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 28 - 1 = 27

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 27 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.0.52

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.052\frac{0.09}{\sqrt{27}} = 0.04[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is $2.58 - $0.04 = $2.54

The upper end of the interval is the sample mean added to M. So it is $2.58 + $0.04 = $2.62.

The 95% confidence interval for the population mean gas price in Gainesville is between $2.54 and $2.62.

Answer:

the percent error is -17.2%

Step-by-step explanation:

The computation of the percent error is shown below:

As we know that

Percent error is

= (Experimental value - theoretical value) ÷ (theoretical value)

= (4.8 - 5.8) ÷ (5.8)

= -17.2%

Hence, the percent error is -17.2%

Answer:

  y = 1400 -140x

Step-by-step explanation:

In the first two months, Zachary paid ...

  1400 -1120 = 280

so 280/2 = 140 per month. This is the amount that the balance decreases each month from the starting balance of $1400.

Zachary's balance (y) can be modeled as ...

  y = 1400 -140x

Step-by-step explanation:

Answer:

You need to have an average speed of at least 35 miles per hour for the rest of the trip to get to the church on time

Step-by-step explanation:

We use the following relation to solve the question:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity, d is the distance, and t is the time.

First 15 minutes:

Time of 15 minutes = 0.25 hour, so [tex]t = 0.25[/tex]

Velocity of 5 miles per hour. So the distance is of:

[tex]d = vt = 5*0.25 = 1.25[/tex]

Final 15 minutes:

The will need to drive 10 - 1.25 = 8.75 miles in 15 minutes = 0.25 hours. So, the average speed will need to be of at least:

[tex]v = \frac{d}{t} = \frac{8.75}{0.25} = 35[/tex]

You need to have an average speed of at least 35 miles per hour for the rest of the trip to get to the church on time

Answer:

The x-intercept is [tex]\frac{1}{8}[/tex]

The y-intercept is -1

Step-by-step explanation:

Lets find x-intercept:

for y substitute 0

4x+0=12x-1

subtract 4x both sides

0=8x-1

add 1 both sides

1=8x

divide 8 both sides

[tex]\frac{1}{8}[/tex]=x

lets find y-intercept:

for x substitute 0

4(0)+y=12(0)-1

multiply 4(0) and 12(0) which would equal 0 in this case, you dont have to write the 0s.

y=-1
