Maria must cut an additional $70 from her expenses each month in order to save enough money to buy a new TV that costs $420 in 6 months. By allocating this additional amount towards her savings goal, she will be able to reach her target within the desired timeframe. It's important for Maria to review her budget and identify areas where she can reduce expenses in order to make room for the additional savings. This could involve cutting back on discretionary spending, finding ways to save on daily expenses, or exploring opportunities to increase her income.

Maria must cut an additional $70 from her expenses each month.

To determine how much additional money Maria must cut from her expenses each month to afford a new TV that costs $420 in 6 months, we divide the total cost by the number of months.

Additional money per month = Total cost / Number of months

Additional money per month = $420 / 6

Additional money per month = $70

With careful planning and commitment to her budget, Maria can achieve her goal of purchasing a new TV without compromising her financial stability.

Step-by-step explanation:

Answer:

Step-by-step explanation:

correct answer : B

Answer:

1 full physical and 33 routine visits per day to maximize income for the day.

Maximum income is $2080.

Step-by-step explanation:

The doctor has 9 hours per day which equals to 9 x 60 = 540 minutes

If there are 10 physicals per day, the maximum minutes will be 45 x 10 = 450 minutes.

so the time left for routine office visits will be 540 - 450 = 90 minutes

then the number of routine office visits will be 90 / 15 = 6

Her income will be ($100 x 10) + ($60 x 6) = 1000 + 360 = $1360

If there is 1 physical per day, then the time will be 45 x 1 = 45 minutes

so time left for routine office visits will be 540 - 45 = 495 minutes

then the number of routine office visits will be 495 / 15 = 33

Her income will be ($100 x 1) + ($60 x 33) = 100 + 1980 = $2080

If there are 2 physicals per day, then the time will be 45 x 2 = 90 minutes

so time left for routine office visits will be 540 - 90 = 450 minutes

then the number of routine office visits will be 450 / 15 = 30

Her income will be ($100 x 2) + ($60 x 30) = 200 + 1800 = $2000

Answer:

Step-by-step explanation:

You want to maximize the doctor's income when she makes $60 for a 15-minute routine visit and $100 for a 45-minute physical. She can work 9 hours per day.

For a routine visit, the doctor is charging $60 for 15 minutes, or $4 per minute.

For a physical, the doctor is charging $100 for 45 minutes, or $2.22 per minute.

Clearly, the doctor earns income faster by spending her time doing routine office visits. There appears to be no limit on the number of those she can do.

Working 9 hours at $4 per minute, the doctor earns ...

  (9 h/day)(60 min/h)($4/min) = $2160/day

The number of routine visits in a day will be ...

  (9 h/day)(60 min/h)/(15 min/visit) = (9·60/15) visits/day = 36 visits/day

The doctor's maximum income is $2160 per day, making 36 routine office visits per day.

__

Additional comment

Each physical will reduce the doctor's income by $80. (In that 45 minutes, she could have done 3 routine visits, for a revenue of 3·60 = 180, instead of the physical for a revenue of 100.)

Answer:

(-2,2)

Step-by-step explanation:

The midpoint is the middle of the line. So, you can take it step-by-step and look at the individual numbers.

Between -6 and 2, that is 8 spaces. So, the middle would be four spaces from one of those numbers. Therefore, X-COORDINATE = -2

Between -3 and 7, that is 10 spaces. So the middle would be 5 spaces from one of those numbers, Therefore, Y-COORDINATE = 2

The width of the tower at the top will be 92 m. Then the correct option is B.

The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.

A cooling tower is 120 meters tall.

The sides of the tower are in the shape of a hyperbola defined by the equation x²/500 – y²/900 = 1 with units in meters.

The center of the tower is at the origin.

Then the width of the tower at the top will be

x²/500 – (120)²/900 = 1

x²/500 – 14400/900 = 1

              x²/500 – 16 = 1

                      x²/500 = 1 + 16

                      x²/500 = 17

                              x² = 8500

                                x = 92.19 ≈ 92 m

Answer:

1/2 is greater than -1 1/2.

Step-by-step explanation:

The random variable has an expected value of 16, an E(x²) value of 288, a mean of 16, a variance of 32, and a standard deviation of 4√2.

To find the expected value (E), mean (μ), variance (σ²), and standard deviation (σ) of the random variable with the probability density function f(x) = (1/288)x on the interval [0, 24], we need to perform the necessary calculations.

Expected value (E):

E(x) is calculated by integrating x * f(x) over the given interval:

E(x) = ∫[0, 24] x * (1/288)x dx

Simplifying:

E(x) = (1/288) ∫[0, 24] x² dx

E(x) = (1/288) [x³/3] evaluated from 0 to 24

E(x) = (1/288) [(24³/3) - (0³/3)]

E(x) = (1/288) [(13824/3) - 0]

E(x) = (1/288) * 4608

E(x) = 16

Therefore, E(x) = 16.

E(x²):

E(x²) is calculated by integrating x² * f(x) over the given interval:

E(x²) = ∫[0, 24] x² * (1/288)x dx

Simplifying:

E(x²) = (1/288) ∫[0, 24] x³ dx

E(x²) = (1/288) [x⁴/4] evaluated from 0 to 24

E(x²) = (1/288) [(24⁴/4) - (0⁴/4)]

E(x²) = (1/288) [(331776/4) - 0]

E(x²) = (1/288) * 82944

E(x²) = 288

Therefore, E(x²) = 288.

Mean (μ):

The mean (μ) is the same as the expected value E(x). So, μ = 16.

Variance (σ²):

Variance (σ²) is calculated as E(x²) - (E(x))^2:

σ² = E(x²) - (E(x))^2

σ² = 288 - (16)^2

σ² = 288 - 256

σ² = 32

Therefore, σ² = 32.

Standard Deviation (σ):

The standard deviation (σ) is the square root of the variance:

σ = √(σ²)

σ = √32

σ = 4√2

Therefore, σ = 4√2.

To summarize:

E(x) = 16

E(x²) = 288

μ = 16

σ² = 32

σ = 4√2

When data from k populations are utilized in an analysis of variance, the mean square between treatments (MSTR) = (C) SSTR/(k - 1).

A statistical method called analysis of variance (ANOVA) is used to examine variations in response variables (continuous random variables) evaluated under settings with discrete factors (classification variables, often with nominal levels).

Analysis of Variance is referred to as ANOVA.

Ronald Fisher created a statistical test in 1918, and it has been in use ever since.

Simply put, an ANOVA analysis determines if the means of three or more independent groups differ statistically.

The mean square between treatments (MSTR) equals SSTR/ when samples from k populations are used in an analysis of variance (k - 1).

Step-by-step explanation:

Ambiguous.  I will assume that you meant:

x+4-7=1  =>  √(x + 4) - 7 = 1

This latter result simplifies to

√(x + 4) = 8

Squaring both sides, we get:  x + 4 = 64, or x = 60  (Answer C)

The value of x is 4.

Option A is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

√(x + 4 - 7) = 1

Square on both sides.

x + 4 - 7 = 1²

x + 4 - 7 = 1

Add 7 on both sides.

x + 4 = 1 + 7

x = 8

Subtract 4 on both sides.

x + 4 - 4 = 8 - 4

The given system of linear equations consists of four equations with four variables: x, y, z, and w. To solve the system, we can use various methods, such as Gaussian elimination or matrix operations.

By performing row operations, we can reduce the system to its row-echelon form or solve it directly to find the values of x, y, z, and w. We will solve the system of linear equations using the method of Gaussian elimination. The augmented matrix representation of the system is:

[1 1 2 -1 | -2]

[0 3 1 2 | 2]

[1 1 0 3 | 2]

[-3 0 1 2 | 5]

First, we'll perform row operations to transform the matrix into the row-echelon form:

R2 = R2 - 3R1

R3 = R3 - R1

R4 = R4 + 3R1

The resulting matrix after these operations is:

[1 1 2 -1 | -2]

[0 0 -5 5 | 8]

[0 0 -2 4 | 4]

[0 3 1 2 | 5]

Next, we'll perform additional row operations to further simplify the matrix:

R4 = R4 - 3R2

The matrix now becomes:

[1 1 2 -1 | -2]

[0 0 -5 5 | 8]

[0 0 -2 4 | 4]

[0 3 1 2 | -19]

Finally, we'll perform the last row operation:

R3 = R3 + 2R2

The matrix is now in row-echelon form:

[1 1 2 -1 | -2]

[0 0 -5 5 | 8]

[0 0 0 14 | 20]

[0 3 1 2 | -19]

From this row-echelon form, we can solve for the variables. Starting from the bottom row, we obtain:

3w + z + 2w = -19, which simplifies to 5w + z = -19.

Next, we have 0x + 0y - 5z + 5w = 8, which simplifies to -5z + 5w = 8.

Lastly, x + y + 2z - w = -2.

At this point, we have three equations with three variables: x, y, and z. By solving this simplified system, we can find the values of x, y, and z.
