Answer:

You would round down, but not to 3. You would round it down to 4.

Step-by-step explanation:

If a decimals last digits are five or more, you would round up. But 4.22 would be rounded down because its less than 5.

Answer:

-3,3 this is because that is where both of the lines intersect making them both a solution for both equations.

Step-by-step explanation:

Answer:

B. (-3, 3)

Step-by-step explanation:

Point of intersection of both the lines is the solution to both the equations.

Both the lines are intersecting each other at point (-3, 3)

So, ordered pair of solution is (-3, 3)

Answer:

-18.00

Step-by-step explanation:

-12.75-5.25

Its going to be a negative number since the greatest number is a negative.

Since its both negative signs you add

12.75+5.25=18.00

Now make it negative.

-18.00

Hope this helps!!!

Have a great day!!! :)

Answer:

Step-by-step explanation:

For a solution to occur y=y so we can say

3x=2x+2 subtract 2x from each side

x=2, since y=3x

y=3(2)

y=6, so the solution exists at the point

The groups of values plugged into the TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly are,

N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.

The correct option is C.

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

Given:

TVM Solver of a graphing calculator will give the monthly payment for a 30-year loan for $265,000 at 5.9% interest, compounded monthly.

Then,

N: The overall amount of payments. Calculating this is simple if you multiply the P/Y by the number of years.

I%: Interest rate per year. Enter this rate as a percentage at all times!

Present Value, or PV: This is the sum of your investment or the loan.

PMT: The sum due.

Future Value (FV): This is your desired level of savings or, if you are calculating loans, your projected loan balance at maturity.

P/Y: The quantity of payment intervals per year.

C/Y: The quantity of compounding cycles each year.

N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END

Therefore,  N=360, 1% = 5.9; PV=-265000; PMT=; FV=0; P/Y=12; C/Y=12; PMT:END.

Step-by-step explanation:

He needs $100 for the new bike but already has the $28 so you also have to add 12x because thats what you need to find. X represents the amount of days he has to work.

Answer:

(x+2)^2+(y-3)^2=100

Step-by-step explanation:

so the equation is (x-h)^2+(y-k)^2=r^2

(h,k)=center

r^2=radius

in this case (h,k)=(-2,3)

r^2=r^2

10^2=100

(x-(-2))^2+(y-3)^2=100

Answer:

c = 31.5

Step-by-step explanation:

Given c varies directly as [tex]\sqrt{d}[/tex] then the equation relating them is

c = k[tex]\sqrt{d}[/tex] ← k is the constant of variation

To find k use the condition c = 14 when d = 64, then

14 = k ×[tex]\sqrt{64}[/tex] = 8k ( divide both sides by 8 )

1.75 = k

c = 1.75[tex]\sqrt{d}[/tex] ← equation of variation

When d = 324 , then

c = 1.75 × [tex]\sqrt{324}[/tex] = 1.75 × 18 = 31.5

Answer:

Slope of 1.5 means that the printing of each new t-shirt is of $1.50.

The y-intercept of 20 means that the fixed cost, that is, the cost without printing the t-shirts, only the design, is of $20.

Step-by-step explanation:

Equation of a line:

An equation of a line has the following format:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the increase in y when x increases by 1.

b is the y-intercept, which is the value of y when x = 0.

The cost, y, to print x T-shirts is y=1.5x+20.

Slope of 1.5 means that the printing of each new t-shirt is of $1.50.

The y-intercept of 20 means that the fixed cost, that is, the cost without printing the t-shirts, only the design, is of $20.

Answer:

12) Between 40 and 64 = 0.815

13) Between 32 and 40 = 0.0235

14) Between 56 and 64 = 0.34

15) At most 56 = 0.515

16) At least 72 = 0.025

17) At most 64 = 0.855

Explanation:

To answer this, we will convert each of the values into their standardized form to make this easier.

The standardized score for any value is the value minus the mean then divided by the standard deviation.

z = (x - μ)/σ

x = Each value

μ = Mean = 56

σ = Standard deviation = 8

12) Between 40 and 64

For 40,

z = (x - μ)/σ = (40 - 56)/8 = (-16/8) = -2

For 64

z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1

So,

Between 40 and 64 = Between -2 and 1

From the curve, noting that the central point is the mean, with standard score of 0, the lines before it move in step of 1 standard deviation towards the negative side, that is, -1, -2, etc. And the lines before the central point move towards the positive side, that is, 1, 2, 3, etc.

So,

Between -2 and 1 = 0.135 + 0.34 + 0.34 = 0.815

13) Between 32 and 40

For 32,

z = (x - μ)/σ = (32 - 56)/8 = (-24/8) = -3

For 40,

z = (x - μ)/σ = (40 - 56)/8 = (-16/8) = -2

So,

Between 32 and 40 = Between -3 and -2 = 0.0235

14) Between 56 and 64

For 56,

z = (x - μ)/σ = (56 - 56)/8 = (0/8) = 0

For 64,

z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1

Between 56 and 64 = Between 0 and 1 = 0.34

15) At most 56

For 56,

z = (x - μ)/σ = (56 - 56)/8 = (0/8) = 0

At most 56 = At most 0 = 0.0015 + 0.0235 + 0.15 + 0.34 = 0.515

All the regions before z = 0)

16) At least 72

For 72,

z = (x - μ)/σ = (72 - 56)/8 = (16/8) = 2

At least 72 = At least 2 = 0.0235 + 0.0015 = 0.025

(All the regions from z = 2 to the end)

17) At most 64

For 64,

z = (x - μ)/σ = (64 - 56)/8 = (8/8) = 1

At most 64 = At most 1 = 0.0015 + 0.0235 + 0.15 + 0.34 + 0.34 = 0.855

(All the regions before z = 1)
