Answer:

The aswer is B

Step-by-step explanation:

You can find the equetion by calculating the X-intercept and Y-intercept of equetion but You simply find it by it's slop and by b ( y-intersept).

So we use the short cut method

Y= mx + b

The slop is down ward (Q2 to Q4) so it's slop is negative.

and the y-intersept is b which is 4 so these answer consistes in B .

Answer:

95$

Step-by-step explanation:

Since there are 5 premium channels, we multiply the rate of charges by the number of premium channels to get the extra payment.

5 channels x 12$ per channel = 50$  

Now we add this to 35 since C= 35 + 12 or 35 plus the premium channel costs

35$ + 50 = 95$

The vendor sold 172 sodas and 58 hotdogs at the hockey game.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

let, the number of soda cans be 'x' and the number of hot dogs be 'y'.

So, From the given information x = 3y and the vendor sold a total of 232.

Therefore, x + y = 232.

3y + y = 232.

4y = 232.

y = 232/4.

y = 58.

So, He sold 58 hot dogs and 3×58 = 172 soda cans.

T test is used to compute the confidence interval, when the mean and standard deviation is given.

What is Standard Deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be very close to the set mean. The lower case Greek letter (sigma), again for population standard deviation, or even the Latin letter s, again for sample standard deviation, are most frequently used in mathematical texts and equations to represent standard deviation. Standard deviation may be abbreviated as SD. A random variable, specimen, statistical population, data set, as well as probability distribution's standard deviation is equal to the square root of its variance. When the number in a sample, sample mean and sample standard deviation is given, the test statistic that should be used when computing a confidence interval is t test

Step-by-step explanation:

Skateboard $125.95 at 40% off is $75.57

How I got the number:

125.95/100 = 1.2595

1.2595 x 40 = 50.38

125.95 - 50.38 = 75.57

Skateboard $169.95 at 60% off is $67.98

169.95/100 = 1.6995

1.6995 x 60 = 101.97

169.95 - 101.97 = 67.98

Therefore the skateboard that is 60% off is cheaper.

The quotient of the rational expressions shown above is given by, Answer: option (C) 7x²/6x-10

To simplify the expression 7x² / 3x-5 / 2x+6 / x+3

We need to perform the following steps:

Invert the divisor.

Change the division to multiplication.

Factor the numerator and denominator.

First, divide the first term in the numerator (7\(x^2\)) by the first term in the denominator (2x) to get 3.

Then multiply (2x + 6) by 3 to get 6x + 18 Subtract this from the numerator.

2x + 6 | 7\(x^2\) + 3x - 5

- (6x + 18)

_______

-3x - 23

Then subtract the following term from the numerator: -3x.

Dividing -3x by 2x gives -3/2.

Multiply (2x + 6) by -3/2. The result is -3x - 9.

Subtract this from the previous result.

3 - (3/2)x

_________

2x + 6 | - 14

The inverse transform of a signal H(z) can be found by solving for h(n). The inverse Z-transform can be obtained by;h(n) = [(-1/2) ^ (n-1) sin(n)] u(n - 1)

The inverse transform of a signal H(z) can be found by solving for h(n).

Here’s how to find the inverse transform of

H(z) = (z^2 - z) / (z^2 + 1)

1: Factorize the denominator to reveal the rootsz^2 + 1 = 0⇒ z = i or z = -iSo, the partial fraction expansion of H(z) is given by;H(z) = [A/(z-i)] + [B/(z+i)] where A and B are constants

2: Solve for A and B by equating the partial fraction expansion of H(z) to the original expression H(z) = [A/(z-i)] + [B/(z+i)] = (z^2 - z) / (z^2 + 1)

Multiplying both sides by (z^2 + 1)z^2 - z = A(z+i) + B(z-i)z^2 - z = Az + Ai + Bz - BiLet z = i in the above equation z^2 - z = Ai + Bii^2 - i = -1 + Ai + Bi2i = Ai + Bi

Hence A - Bi = 0⇒ A = Bi. Similarly, let z = -i in the above equation, thenz^2 - z = A(-i) - Bi + B(i)B + Ai - Bi = 0B = Ai

Similarly,A = Bi = -i/2

3: Perform partial fraction expansionH(z) = -i/2 [1/(z-i)] + i/2 [1/(z+i)]Using the time-domain expression of inverse Z-transform;h(n) = (1/2πj) ∫R [H(z) z^n-1 dz]

Where R is a counter-clockwise closed contour enclosing all poles of H(z) within.

Answer: Let's solve this problem step by step.

First, let's assume the salaries of An and B to be 5x and 3x, respectively, where x is a common multiplier.

According to the given information, they save Rs. 2600 and Rs. 1800, respectively. Since savings come from the remaining portion of their incomes after spending, we can calculate their expenditures as follows:

For An:

Income of An = Salary of An + Savings of An

Income of An = 5x + 2600

For B:

Income of B = Salary of B + Savings of B

Income of B = 3x + 1800

Now, let's consider the proportion of their expenditures. It is given that the proportion of their expenditures is 9:5. So, we can write the following equation:

(Expenditure of An)/(Expenditure of B) = 9/5

Since expenditure is the complement of savings, we have:

[(Income of An - Savings of An)] / [(Income of B - Savings of B)] = 9/5

Substituting the previously derived expressions for income, we get:

[(5x + 2600 - 2600)] / [(3x + 1800 - 1800)] = 9/5

Simplifying the equation, we have:

5x / 3x = 9/5

Cross-multiplying, we get:

5 * 3x = 9 * 3x

15x = 27x

Subtracting 27x from both sides, we have:

0 = 12x

This implies that x = 0, which is not a valid solution. Therefore, there seems to be an error or inconsistency in the given information or equations. Please recheck the problem statement or provide additional information to help resolve the issue.

Answer: The probability that a person who could give up her cell phone could also give up television is 0.7 or 70%.

Probability is an essential branch of mathematics that helps individuals analyze the likelihood of events occurring. The probability of events is estimated using theoretical or experimental probability. The experimental probability of an event is based on actual outcomes or trials, while theoretical probability is based on a mathematical model. Additionally, a person is someone who is a biological entity capable of making decisions and responding to external stimuli. Hence, the probability that a person who could give up her cell phone could also give up television is estimated below.Suppose 70% of individuals who give up their cell phones can also give up their televisions. The probability that a person who could give up her cell phone could also give up television is estimated as follows:P(Give up television | Give up cell phone)

= P(Give up television and Give up cell phone) / P(Give up cell phone)

= 70% / 100%

= 0.7

The probability that a person who could give up her cell phone could also give up television is 0.7 or 70%. Thus, the chances of someone giving up their cell phone and television is 70%.
