Answer:

for every extra mile an employee drives, the driving time increases by 1.3 minutes

Step-by-step explanation:

Step 1: The given regression equation y = 1.3x + 6.8, where "x" is the number of miles and "y" is the time taken.

Step 2: Here the constant 6.8 remains the same. For each extra mile, the time increases by 1.3

For example, let's take x = 2 miles, the time taken y = 1.3(2) + 6.8

= 2.6 + 6.8

y = 9.4

Let's take x = 3, the time taken y = 1.3(3) + 6.8

= 3.9 + 6.8

y =10.7

You can see the difference in the timing by 1.3.

Therefore, for each extra mile, the time is increases by 1.3 minutes.

Thank you.

Daniel invests $2,037 in a retirement account with a fixed annual interest rate of 6% compounded 6 times per year. What will the
notka56 [123]

Answer:

\$5294.72

Step-by-step explanation:

GIVEN: Daniel invests \$2,037 in a retirement account with a fixed annual interest rate of 6\% compounded 6 times per year.

TO FIND: What will the account balance be after 16 years

SOLUTION:

Amount invested by Daniel =\$2037

Annual interest rate =6\%      

Total amount generated by compound interest is  =P(1+\frac{r}{n})^n^t

Here Principle amount P=\$2037

rate of interest r=6\%

number of times compounding done in a year n=6

total duration of time nt=16\text{ years}

putting values we get

=2037(1+\frac{6}{6\times100})^1^6

=2037(\frac{101}{100})^1^6

=\$5294.72

Hence the total balance after 16\text{ years} will be \$5294.72

The perimeter of XYZ is ___ units.
In-s [12.5K]

Look at the picture.

ZY = 5+3=8

For XY and ZX use the Pythagorean theorem.

XY^2=3^2+4^2\\\\XY^2=9+16\\\\XY^2=25\to XY=\sqrt{25}\\\\XY=5

ZX^2=5^2+4^2\\\\ZX^2=25+16\\\\ZX^2=41\to ZX=\sqrt{41}

The perimetero fo XYZ:

P_{\triangle XYZ}=8+5+\sqrt{41}=\boxed{13+\sqrt{41}}

Sara Blake's grandmother gave her $3000.00 to save for college. She put it in a savings account that earns 6% interest per year.
Elina [12.6K]

• P is the principal amount, $3000.00.

• r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.

• t is the time involved, 8 years time periods.

• So, t is 8 year time periods.

To find the simple interest, we multiply 3000 × 0.06 × 8 to get that:

The interest is: $1440.00

What is the slope and y-intercept of y+3= -1/3
bazaltina [42]

Assuming this is written correctly, with no x in the equation, we just solve for y:

y = -3 - 1/3 = -10/3 = 0 x - 10/3

That's slope-intercept form.

Answer: Slope 0, y-intercept -10/3
