Michelle's phone plan charges $0.22 per text message. Jeff's plan charges $0.12 a text plus an additional $1 a day. for what number of texts are the cost of the phone plans the same? write an algebraic equation and solve.

Answers

Answer 1

Answer:

Let's assume that the number of text messages sent in a day is x. Then the cost of Michelle's phone plan is:

Cost of Michelle's plan = 0.22x

And the cost of Jeff's phone plan is:

Cost of Jeff's plan = 0.12x + 1

We want to find the number of text messages for which the two plans have the same cost. So we can set the two expressions for the cost equal to each other and solve for x:

0.22x = 0.12x + 1

0.1x = 1

x = 10

Therefore, for 10 text messages per day, the cost of Michelle's plan and Jeff's plan will be the same.

We can also verify this by plugging x = 10 into the two expressions for the cost:

Cost of Michelle's plan = 0.22(10) = $2.20

Cost of Jeff's plan = 0.12(10) + 1 = $2.20

So the cost of the two plans is indeed the same for 10 text messages per day.

Answer 2

Answer:

Step-by-step explanation:

cost m = 0.22x

cost j = 0.12x+1

0.22x=0.12x+1

0.1=1

x=10

cost m = 0.22(10) = $2.20

cost J =0.12(10)+1=$2.20

So the answer is 10

9. A box contains three blue bulbs, four green bulbs and five red bulbs. Four bulbs taken out of the box at random and without replacements. What is the probability that: (1) are the first two are of the same colour and the last two are of different colours. ​

Answers

The probability that the first two bulbs are of the same colour and the last two are of different colours is 25/48.

The probability that the first two bulbs are of the same colour and the last two are of different colours is calculated as follows:

Given:

n(B) = 3 (Number of blue bulbs)

n(G) = 4 (Number of green bulbs)

n(R) = 5 (Number of red bulbs)

Formula: P(A) = n(A) / n(S)

Where,

P(A) = Probability of event A

n(A) = Number of favorable outcomes

n(S) = Number of possible outcomes

The probability of selecting two bulbs of the same colour is calculated as:

P(SS) = n(B) * n(B) / n(S)

= 3 * 3 / 12

= 1/4

The probability of selecting two bulbs of different colour is calculated as:

P(DD) = n(B) * n(G) * n(R) * n(R) / n(S)

= 3 * 4 * 5 * 5 / 12

= 25/12

Therefore, the required probability is calculated as:

P(SSDD) = P(SS) * P(DD)

= 1/4 * 25/12

= 25/48

Answers

The three equations that have the same value of x as the original equation are:

18x - 15 = 72

3(6x - 3) = 72

x = 4.5

What is an equation?

An equation is a statement that two expressions are equal. It typically contains one or more variables (represented by letters) and mathematical operations such as addition, subtraction, multiplication, and division. Equations can be used to represent relationships between quantities or to solve for unknown values.

The correct options are:

18x - 15 = 72

18x - 9 = 72

x = 4.5

To see why, we can start by simplifying the original equation:

Three-fifths (30x - 15) = 72

(3/5)(30x - 15) = 72

18x - 9 = 72

18x - 15 = 72 + 15

18x = 87

x = 87/18

So we see that x = 87/18 is the solution to the original equation.

Now let's check each of the answer choices:

18x - 15 = 72

Solving for x, we get x = 87/18, which is the same as the solution to the original equation. This equation is equivalent to the original equation.

50x - 25 = 72

Solving for x, we get x = 97/50, which is not the same as the solution to the original equation. This equation is not equivalent to the original equation.

18x - 9 = 72

Solving for x, we get x = 81/18 = 9/2, which is not the same as the solution to the original equation. This equation is not equivalent to the original equation.

3(6x - 3) = 72

Simplifying, we get 18x - 9 = 72, which is equivalent to the second equation listed above. So this equation is also equivalent to the original equation.

x = 4.5

This is the same solution as the original equation, so this equation is also equivalent to the original equation.

Therefore, the three equations that have the same value of x as the original equation are:

18x - 15 = 72

3(6x - 3) = 72

x = 4.5

solve the system of linear equation by elimination 8x+3y=-5
3y=x+4 please show work

Answers

The solution of linear equations is (x, y) = (-0.8905, 0.708).

To solve this system of linear equations by elimination, first multiply both equations by the same number so that when you add the equations together, one of the variables is eliminated. In this case, we'll multiply the first equation by 3 and the second equation by 8.

8(8x+3y=-5)

3(3y=x+4)

24x + 9y = -15

24y = 8x + 32

Now add the two equations together:

24x + 24y = -15 + 32

24x + 24y = 17

Simplifying this equation, we get:

24y = 17

y = 17/24

y = 0.708

Now, plug in the value of y into one of the original equations to solve for x. We'll use the first equation:

8x + 3(0.708) = -5

8x + 2.124 = -5

8x = -7.124

x = -7.124/8

x = -0.8905

Therefore, the solution to the system of linear equations is (x, y) = (-0.8905, 0.708).

Answer:

Option B

See below

Step-by-step explanation:

Two simultaneous equations:

[tex]7x - 4y - 8 = 0[/tex] —————- (equation i)

[tex]2x^{2} + x + 4y + 8 = 0[/tex]   ——- (equation ii)


Step 1:

Rearrange (equation i):

[tex]7x - 4y = 8[/tex] ———- updated (equation i)

Step 2:

Substitute the updated (equation i) into (equation ii) and bring like terms together to simplify them in reduced forms:

[tex]2x^{2} + x + 4y + (7x - 4y) = 0[/tex]

[tex]2x^{2} + x + 4y + 7x - 4y = 0[/tex]

[tex]2x^{2} + x + 7x + 4y - 4y = 0[/tex]

[tex]2x^{2} + 8x = 0[/tex]


Step 3:

Factorize:

[tex]2x(x + 4) = 0[/tex]

Either [tex]2x = 0[/tex]        
∴ [tex]x = 0[/tex]


Or [tex]x + 4 = 0[/tex]

∴ [tex]x = -4[/tex]


Step 4:

Substitute these values of x in (equation ii) to determine their corresponding values of y:

For x = 0:

[tex]2(0)^{2} + 0 + 4y + 8 = 0[/tex]

[tex]4y + 8 = 0[/tex]

[tex]4y = -8[/tex]

[tex]y = \frac{8}{-4}[/tex]

∴[tex]y = -2[/tex]


For x = -4:

[tex]2(-4)^{2} + (-4) +4y + 8 = 0[/tex]

[tex]2(16) - 4 + 4y + 8 = 0[/tex]

[tex]32 - 4 + 4y + 8 = 0[/tex]

[tex]32 - 4 + 8 + 4y = 0[/tex]

[tex]36 + 4y = 0[/tex]

[tex]4y = -36[/tex]

[tex]y = \frac{-36}{4}[/tex]

The equation of the volume of the box in terms of x is 4x³ - 40x² +100x.

What is the V(x) function's domain?

The set of all conceivable values of x that make sense in the context of the issue constitutes the domain of the function V(x). This time, x must be a positive value less than or equal to 5, as it reflects the length of the side of the square that was cut out of each corner of the cardboard. The range of V(x) is thus 0 x 5.

Given that, the squares cut at the end are x inches.

Thus the dimension of the rectangular box are:

The length of the box will be (10-2x).

The width of the box will be (10-2x).

The height of the box will be x inches.

The volume of the rectangular box is given by:

V = (l)(w)(h)

Substituting the values we have:

V(x) = (10-2x)(10-2x)x = x(100-40x+4x^2) = 4x³ - 40x² +100x.

Hence, the equation of the volume of the box in terms of x is 4x³ - 40x² +100x.

3. 5x/7 - 2x/7

Answers

1). 1/4

2). 11/15x

3). 3x/7

1. To add or subtract the rational expressions 5/8 and 3/8x, we need a common denominator. The smallest common denominator is 8x, so we can rewrite each expression with a denominator of 8x:

5/8 = 5x/8x

3/8x = 3/8 * 1/x = 3x/8x

Now we can combine the numerators and simplify:

5x/8x - 3x/8x = (5x - 3x)/8x = 2x/8x = 1/4

Therefore, 5/8 - 3/8x = 1/4.

2. To add or subtract the rational expressions 9/15x and 2/15x, we again need a common denominator. The smallest common denominator is 15x, so we can rewrite each expression with a denominator of 15x:

9/15x = 3/5x

2/15x = 2/15 * 1/x = 2/15x

Now we can combine the numerators and simplify:

3/5x + 2/15x = (9 + 2)/15x = 11/15x

Therefore, 9/15x + 2/15x = 11/15x.

3. To add or subtract the rational expressions 5x/7 and -2x/7, we already have a common denominator of 7. We can simply combine the numerators:

5x/7 - 2x/7 = (5x - 2x)/7 = 3x/7

Answers

The probability that a person chosen at random from this group will either seek further assistance or merely study at home is 5/6, or roughly 0.833. (rounded to three decimal places).

What is the probability formula?

Typically, the probability is defined as the ratio of favourable events to all other outcomes in the sample space. The formula for probability of an occurrence is P(E) = (Number of favourable outcomes) (Sample space).

The formula is as follows:

P(AorB) = P(A)+P(B)-P(AandB)

where A and B are two events.

Then, we have:

P(A) = 30/60 = 1/2 (since 30 out of 60 students go for extra help)

P(B) = 22/60 (since 22 out of 60 students study at home only)

Using the formula, we can then find:

P(AorB) = P(A)+P(B)-P(AandB)

= 1/2 + 22/60 - 0

= 5/6

Hence, the probability that someone chosen at random from this group will either seek further assistance or merely study at home is 5/6, or roughly 0.833. (rounded to three decimal places).

Answers

The slide does not meet safety requirements.

What is Slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

As per the given data:

maximum average slope = 30°

height of the slide = 6 ft

length of the slide = 11.7 ft

For calculating slope (θ):

sinθ = (P/H) {P is perpendicular and H is hypotunese}

sinθ = (height/length)

sinθ = (6/11.7)

sinθ = 0.512

Using sin inverse:

θ = 30.8°

After pouring x ml of liquid from container B to container A, the total volume of liquid in container A will be (750 + x) ml, and the total volume of liquid in container B will be (1250 - x) ml.

Since we want the volumes of both containers to be equal, we can set up the equation:

Find the present value PV of the annuity necessary to fund the withdrawal given. HINT [See Example 3.] (Assume end-of-period withdrawals and compounding at the same intervals as withdrawals. Round your answer to the nearest cent.) $500 per month for 15 years, if the annuity earns 6% per year PV = $

Answers

The present value PV of the annuity necessary to fund the withdrawal is $5,354.82, rounded to the nearest cent.

The present value of an annuity is calculated using the following formula:

PV = A[((1+i)n-1)/(i(1+i)n)]

where A = amount of each annuity payment, i = interest rate, and n = number of payments.

For this problem, A = $500, i = 6%, and n = 15 years.

Therefore, the present value of the annuity necessary to fund the withdrawal is:

PV = $500[((1+0.06)15-1)/(0.06(1+0.06)15)]

PV = $500[5.72982/0.105638]

PV = $5,354.82

Therefore, the present value PV of the annuity necessary to fund the withdrawal is $5,354.82, rounded to the nearest cent.

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = - x⁴ + 5x³ - 2x + 5

Now, We have;

Degree of the polynomial = 4

Hence, We get;

⇒ The right-end is  y → - ∞ as x → ∞ . The right-end is rising.

The left-end is y → - ∞  as x→ - ∞ . The left-end is falling.

Prove for the simple decision sapling (sure thing of value r vs. risky gamble), that EVPI > 0. Also prove that if the random payoff of the gamble, call it G, is replaced by the random variable G+Y where Y is independent of G and EY = 0 (so G’ = G+Y is a noisy, or more variable, version of the original gamble G), then the EVPI will be larger. a

Answers

To prove that EVPI > 0 for the simple decision sapling, we need to understand what EVPI is. EVPI stands for Expected Value of Perfect Information, and it is the difference between the expected value of the decision with perfect information and the expected value of the decision without perfect information.

For the simple decision sapling, we have two options: a sure thing of value r, and a risky gamble with a random payoff G. The expected value of the decision without perfect information is simply the maximum of the two options:
EV = max(r, EG)
The expected value of the decision with perfect information is the maximum of the two options, knowing the outcome of the gamble:
EVPI = max(r, G) - max(r, EG)
Since we know that G is a random variable, the expected value of G is simply the average of all possible outcomes. Therefore, the expected value of the decision with perfect information is simply the maximum of the two options, knowing the average outcome of the gamble:
EVPI = max(r, EG) - max(r, EG) = 0
Therefore, EVPI > 0 for the simple decision sapling.

To prove that the EVPI will be larger if the random payoff of the gamble is replaced by a noisy version of the original gamble, we need to understand how the expected value of the decision changes with the addition of the noise variable Y. The expected value of the decision without perfect information is now:
EV = max(r, EG + EY) = max(r, EG)
Since EY = 0, the expected value of the decision without perfect information does not change. However, the expected value of the decision with perfect information now becomes:
EVPI = max(r, G + Y) - max(r, EG)
Since Y is a random variable with mean 0, the expected value of Y is 0. However, the variance of Y is not necessarily 0, which means that the addition of Y adds variability to the decision. This means that the expected value of the decision with perfect information is now larger, because we have more information about the possible outcomes of the gamble. Therefore, the EVPI will be larger when the random payoff of the gamble is replaced by a noisy version of the original gamble.

You randomly draw a marble from a bag, record its color, and then replace it. You draw a blue marble 23 out of 25 times. What is the experimental probability that the next marble will be blue? Write your answer as a fraction, decimal, or percent.

Answers

The next marble's experimental probability of being blue, according to an experiment, is: 23/25.

Explain about the experimental probability?

Based on empirical data, experimental probability is the likelihood that an event will occur. A theoretical probability would be obtained by dividing the number of different ways to achieve the desired result by the total number of outcomes.

A marble is drawn at random from a bag, its colour is noted, and it is then replaced.In 23 of the 25 draws, a blue marble is produced.

The next marble's likelihood of being blue, according to an experiment, is:

Experimental probability = Number of time blue appears / Total outcomes

Experimental probability = 23/25

Thus, the next marble's experimental probability of being blue, according to an experiment, is: 23/25.

Umm soo I kinda need help with math

Answers

Answer:

Option A.

Step-by-step explanation:

We are asked to add these 2 expressions.

First, we should know how to combine like terms.

What is combining like terms?

Combining like terms is adding 2 or more numbers, or variables that are alike.

[tex]-\frac{4}{5} t+\frac{5}{3} s \ + -3 - \frac{7}{5} s+2t=?[/tex]

Let's first begin by combining s and t. We can combine like terms for these two variables.

[tex]-\frac{4}{5} t + 2t = \frac{6}{5} t \ \checkmark[/tex]

[tex]\frac{5}{3} s \ + \frac{7}{5} s \\Which \ can \ also \ be \ represented \ as...\\\frac{25}{15} s \ - \frac{21}{15} s = \frac{4}{15} s \ \checkmark[/tex]

-3 doesn't have any like terms, meaning it'll stay as -3.

[tex]\frac{6}{5} t + \frac{4}{15} s - 3[/tex]

Therefore, our answers matches with Option A.
