whats an inequality?​

Answer:

I thing the answers are C & D

Step-by-step explanation:

MARIA has +18$

HARRY has - 12$

So the differences between them is 30$

But Maria is more then Harry

Also you can say Harry has less than Maria

The following statement is true

Maria's account has 30$ more than Harry's account.​

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.

Given:

Maria's account has a credit = (+$18), and

Harry's account has a debit of (-$12).

now, the difference between Maria's and Harry's account is

=18 - (-12)

=18+12

=+30

As, we know Maria has more money then Harry.

Hence, Maria's account has 30$ more than Harry's account.​

Answer:

x = [-b +- sqrt(b^2-4ac)]/2a

Step-by-step explanation:

Answer:

3) m∡ACB = 40 m∡ABC = 63

4) m∡BCA = 14 m∡ABC = 83

Step-by-step explanation:

Since DE is a line it has 180 degrees so:

103 + CAB = 180

CAB = 77 degrees

All triangle interior angles of a triangle add up to 180 degrees, so:

BAC + ACB + CBA = 180

3x - 14 + 3x + 9 + 77 = 180

6x + 72 = 180

6x = 108

x = 18

Plug in your values:

3(18) - 14 = 40

3(18) + 9 = 63

Use the same method for the next problem.

Step-by-step explanation:

For no.4

m= -2/3

x=-60

y=10

now

y=mx+b

or,

10=-2x/3+b

or, 30=-2(-60)+3b

or, 30 = 120+3b

or,

3b = -90

so, b = -30

now

y=mx+b

or, y = -2x/3-30

for no.4 the equation would be

The pmf of M1 is \($P(M1=k) = \binom{20}{k} \cdot p^k \cdot (1-p)^{20-k}$\)

The probability that more than 11 passengers are riding on the bus is \($P(M > 11) = 1 - P(M\leq11) = 1 - \sum_{k=0}^{11} P(M=k)$\)

The value of E[R] is 20λp and the value of Var(R) is \($20\lambda p(1-p) + \lambda \cdot 20^2 p^2$\)

Given that the number of buses arriving at a station in a specific time interval follows a Poisson distribution with parameter λ, and each bus has 20 seats with a probability p that each seat is taken. The number of passengers in bus number 1, M1, follows a binomial distribution with parameters n=20 and p. Using these distributions, we can calculate the probabilities of different events, the expected value of the total number of passengers, and the variance of the total number of passengers.

The number of passengers on bus 1, M1, follows a binomial distribution with parameters n=20 and p. The pmf of M1 is:

\($P(M1=k) = \binom{20}{k} \cdot p^k \cdot (1-p)^{20-k}$\)

where k ranges from 0 to 20.

The range of M1 is 0 to 20.

When p=0.2, the probability that more than 11 passengers are riding on the bus can be calculated using the Poisson distribution. We can find \($P(M > 11) = 1 - P(M\leq11) = 1 - \sum_{k=0}^{11} P(M=k)$\)

where M is the number of passengers on the bus. We can also use Markov's inequality to find an upper bound on this probability, which is P(M>11) <= E[M]/11.

When p=0.8, we want to compute the probability that there are at most 10 passengers on the bus. We can use the binomial distribution to find P(M1<=10), where M1 is the number of passengers on bus 1. We can also use Chebyshev's inequality to find an upper bound on this probability, which is \(P(\left|M_1-E[M_1]\right|\geq3) \leq \frac{Var(M_1)}{3^2}\)

The expected value of the total number of passengers is \(E[R] = \lambda * E[M]\), where E[M] is the expected number of passengers on a bus. Since each seat has probability p of being taken, we have E[M]=20p. Therefore, E[R] = 20λp.

The variance of the total number of passengers is\($\mathrm{Var}(R) = \lambda\mathrm{Var}(M) + \mathrm{Var}(\lambda)\mathrm{E}(M)^2$\), where Var(M) is the variance of the number of passengers on a bus. Using the binomial distribution, we can find Var(M) = 20p(1-p). Since the Poisson distribution has variance equal to its mean, we have Var(λ) = λ.

Therefore, \($Var(R) = 20\lambda p(1-p) + \lambda \cdot 20^2 p^2$\)

We get the number of bananas as 8 and the number of mangoes as 4.

The general equation of a straight line is -

y = mx + c

{m} - slope.

{c} - intercept along the y - axis.

Given is that Chee and her children went into a grocery store and she bought $12 worth of bananas and mangos. Each banana costs $0.50 and each mango costs $2. She bought twice as many bananas as mangos.

We can write the system of equations as -

x = 2y               .....  (1)

(1/2)x + 2y = 12   ..... (2)

We can write equation (2) as -

(1/2) x 2y + 2y = 12

3y = 12

y = 4

then -

x = 8

The dimensions of the garden that minimize the cost is 3.83 and 5.74.

Lets assume the garden has length L and width W and one Length has the brick wall.

L*W = 22 (area constraint)

C = 40 * L + 20 * L + 20 * W + 20 * W

= 60 * L + 40 * W

We need the equation in terms of just one variable, lets use L. We can use the area constraint to do this

W = 22/L (plug this into the C equation)

C(L) = 60*L + 40*(22/L)

= 60*L + 880/L

C(L) = 60*L + 880/L

now take the derivative and get

C'(L) = 60 - 880/L^2

now set that derivative = 0 to find the key L value where the min/max occurs (min in this case)

0 = 60 - 880/L^2

Solve for L,

L = ± (2 sqrt(11/3))

We only need the positive answer as negative length makes no sense here,

L = 3.83 (approximate)

We can now solve for W as well

The interest earned increases with higher principal amounts, higher interest rates, and longer time periods.

Principal (P) | Interest Rate (r) | Time Period (t) | Interest Earned (I)

$1,000 | 2% | 1 year | $20

$5,000 | 4% | 2 years | $400

$10,000 | 3.5% | 3 years | $1,050

$2,500 | 1.5% | 6 months | $18.75

$7,000 | 2.25% | 1.5 years | $236.25

To calculate the interest earned (I), we can use the simple interest formula: I = P * r * t.

For the first row, with a principal of $1,000, an interest rate of 2%, and a time period of 1 year, the interest earned is calculated as follows: I = $1,000 * 0.02 * 1 = $20.

For the second row, with a principal of $5,000, an interest rate of 4%, and a time period of 2 years, the interest earned is calculated as follows: I = $5,000 * 0.04 * 2 = $400.

For the third row, with a principal of $10,000, an interest rate of 3.5%, and a time period of 3 years, the interest earned is calculated as follows: I = $10,000 * 0.035 * 3 = $1,050.

For the fourth row, with a principal of $2,500, an interest rate of 1.5%, and a time period of 6 months (0.5 years), the interest earned is calculated as follows: I = $2,500 * 0.015 * 0.5 = $18.75.

For the fifth row, with a principal of $7,000, an interest rate of 2.25%, and a time period of 1.5 years, the interest earned is calculated as follows: I = $7,000 * 0.0225 * 1.5 = $236.25.

With reference to graph a, at a price of $10, total revenue equals $400.

By multiplying the total number of items and services sold by their prices, total revenue—the sum of all sales—is determined. The extra money made from selling one more unit of an item or service is known as marginal revenue. The term "revenue" refers to the sum of money that a business makes from the sale of goods and services during the course of its operations. Total earnings or the profit a corporation makes are other names for revenue. The business of the corporation affects the revenue formula. For instance, a product sale is computed by multiplying the total number of product sales by the average price at which the goods are sold.

We can conclude that at least 56% of the data values will fall in the range of $48 to $60.

Given data: The average labor charge for automobile mechanics is $54 per hour.

The standard deviation is $4.

Using Chebyshev’s theorem, we need to find the percentage of data values that will fall in the range of $48 to $60.

Chebyshev's theorem states that at least 1-1/k2 of the data will lie within k standard deviations of the mean of a random data set.

It does not depend on the shape of the data distribution, only the standard deviation is used in the calculations.

The formula for Chebyshev's theorem is:

1-1/k2  where k is the number of standard deviations from the mean.

Let's find the value of k first. k is calculated as:

k = (upper limit of the range - the mean) / the standard deviation

= (60 - 54) / 4

= 1.5k

= (mean - lower limit of the range) / the standard deviation

=  (54 - 48) / 4

= 1.5

Now, we will use Chebyshev's theorem to find the percentage of data that will fall within this range:

1-1/k2 = 1 - 1/1.5²

= 1 - 0.44

= 0.56

There's still a 5.48% chance that you'd find that the average of their 64 wages is $6.90 or less so to assume that the wage rate of the ethnic group is equivalent to that of a random sample of workers from those employed in the service industry is not valid.

If the true mean of this group's wages is also $7.00 and the standard deviation is $0.50, then the average of a sample of n workers has the same mean and a standard deviation of (pop. stan. dev. / √n).

In this case, the sample average is a random variable with a mean of $7.00 and a standard deviation of $0.50/√64 = 0.0625.

If a random variable has a normal distribution with a mean $7.00 and st. dev. $0.0625, then the probability of observing it as $6.90 or less is:

P[sample mean < 6.90] = P[z < (6.90 - 7.00)/0.0625] = P[z < -1.6] = 0.0548.

In other words, it could be the case that there's no discrimination against ethnic workers, and there's still a 5.48% chance that you'd find that the average of their 64 wages is $6.90 or less.
