How many games did they play

Answer:

x = 2

y = 3

Step-by-step explanation:

y = 2x – 1

y - 2x = -1

y = 5x – 7

y - 5x = -7

y - 2x = -1

y - 5x = -7

_________--

3x = 6

x = 6/3

x = 2

y = 2x – 1

y = 2(2) - 1

y = 4 - 1

y = 3

[tex]x=2\\y=3[/tex]

Given -

[tex]y=2x-1\\y=5x-7[/tex]

So, substitute [tex]y=2x-1[/tex] in [tex]y=5x-7[/tex].

[tex]y=5x-7\\2x-1=5x-7\\5x-2x-7+1=0\\3x-6=0\\3x=6\\x=\frac{6}{3} \\x=2[/tex]

Now, substitute [tex]x=2[/tex] in [tex]y=2x-1[/tex].

[tex]y=2x-1\\y=2(2)-1\\y=4-1\\y=3[/tex]

Therefore, [tex]x=2[/tex] and [tex]y=3[/tex].

Answer:

A

Step-by-step explanation:

To determine which expressions are equivalent to -(8 divided by 3), let's perform the calculation first. Therefore the correct option is A

The division of 8 by 3 can be written as 8/3, which equals to 2.6666 (rounded to four decimal places). When we apply the negative sign to this result, we get -(2.6666) or -2.6666. Now, let's consider the given answer choices: A) 8 divided by -3: This expression corresponds to 8/(-3), which equals to -2.6666. Since this matches the calculated value of -2.6666, option A is equivalent.

B) -8 divided by -3: This expression translates to [tex](-8)/(-3),[/tex] which simplifies to 2.6666. As this value does not match the calculated result of -2.6666, option B is not equivalent. Therefore, by comparing the results, we can conclude that option A (8 / -3) is equivalent to -(8 / 3), while option B (-8 / -3) is not. To summarize, the expression -(8 /3) can be represented as 8 by -3 (option A). Option B (-8 / -3) is not equivalent.

Thus, the correct answer is A) 8 /-3.

Answer:

B. f(x) = 4 log(x+3)

Step-by-step explanation:

B. f(x) = 4 log(x+3) : shifted three units to the left of g(x) = 4 logx

The functions would result in a graph that is shifted three units to the left of g(x) = 4 log x is F(x) = = 4log(x+3).

The correct option is B.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have,

G(x) = 4 log x

As, If we want to shift a function to the left, we add a constant.

and, If we want to shift a function to the right, we subtract a constant.

Her, we have to shift left by 3 unit then we have to add.

Then, the translated function F(x) = 4log(x+3)

182 mins - 150 = 32 extra mins = 32 × 15 = 480p or £4.80 for extra texts

16 + 2.60 + 4.80 = £23.40 total for month.

C. Both can be used to withdraw money from ATMs.

A debit card and an ATM card share certain similarities, but they also have distinct differences. Let's focus on the similarities both can be used to withdraw money from ATMs (option c).

The primary similarity between a debit card and an ATM card is that they can both be utilized to withdraw cash from Automated Teller Machines (ATMs). When using either card at an ATM, the cardholder can access their bank account and withdraw funds, check balances, and perform other account-related transactions.

However, it is crucial to note the differences between these two types of cards. A debit card is linked to a checking or savings account and allows the user to make purchases in stores, online, or through other payment methods. It deducts the amount spent directly from the linked bank account. On the other hand, an ATM card is typically used only for ATM transactions and lacks the functionality to make purchases like a debit card.

In summary, both a debit card and an ATM card can be used to withdraw money from ATMs, but a debit card offers additional features and can be used for various transactions, including online and in-store purchases.

Final answer:

Jennifer is 66.3 inches tall; this is calculated by finding the z-score for the 70th percentile and using it with the mean and standard deviation of the population.

Explanation:

To determine how tall Jennifer is, given that she is taller than 70% of the population of U.S. women, we need to find the corresponding z-score that reflects the 70th percentile of a normal distribution, and then use it to calculate her height.

Firstly, using a standard normal distribution table or a calculator, we find the z-score that corresponds to the 70th percentile. Generally, this z-score is around 0.5244 (this can vary slightly depending on the table or technology used to find it). Now we apply the formula for converting a z-score to the actual score using the population mean and standard deviation:

Height = mean + (z-score × standard deviation)

Plugging in the values for the population mean and standard deviation:

Height = 65 + (0.5244 × 2.4)

Height = 65 + 1.2586

Height = 66.2586 inches

After rounding, we conclude that Jennifer is 66.3 inches tall.

In the given case, Jennifer's height is approximately 66.3 inches.

To find Jennifer's height, we need to find the z-score corresponding to the 70th percentile (as she is taller than 70% of the population) and then use that z-score to find her height.

The z-score formula is:

[tex]\[ z = \frac{x - \mu}{\sigma} \][/tex]

First, we find the z-score corresponding to the 70th percentile using a standard normal distribution table or calculator.

A z-score of approximately \(0.5244\) corresponds to the 70th percentile.

Now, we can use the z-score formula to find Jennifer's height x

[tex]\[ 0.5244 = \frac{x - 65}{2.4} \][/tex]

[tex]\[ x \approx 66.2586 \][/tex]

Rounded to one decimal place, Jennifer's height is approximately 66.3 inches.

1/10 or 10%.

First, you add up all the quarters to get the total amount of possibilities for the first quarter that gets pulled out.

4 NY + 3 PA + 3 VI = 10 total quarters.

So the total number of quarters becomes the denominator for the first probability, and the total number  of PA quarters becomes the numerator.

So the probability of Jim pulling out a PA quarter first is 3/10.

Now you have to find the probability of drawing a VI quarter as the second quarter. Since it's known that Jim would have already pulled 1 quarter out, that means the total number of quarters he could draw is now 9, so 9 would be the denominator of the second probability. Since there should be 3 VI quarters left still in his pocket, the numerator for the second probability is 3.

So the probability of Jim pulling out a VI quarter second is 3/9.

Now to get the final probability of Jim pulling out both a PA quarter and a VI quarter in the correct order, all you have to do is multiply the two probabilities together and then you should get the probability of the correct quarters being pulled out inn the correct order.

The first probability, 3/10, times the second probability, 3/9 equals the total probability of 9/90, and it simplifies to 1/10 or 10%

Step-by-step explanation:

Answer: SECOND OPTION.

Step-by-step explanation:

It is important to remember that, by definition, the "Resultant vector " is the vector obtained by adding two or more vectors.

 For this exercise you need to use the formula for calculate the magnitude of the resultant vector obtained by adding the vectors "a" and "b" shown in the picture attached:

[tex]c=\sqrt{a^2+b^2}[/tex]

Where "c" is the magnitude of the resultant vector asked in the exercise.

You need to analyze the graph given in the exercise.

You can identify that:

[tex]a=4\\\\b=3[/tex]

Then the next step, knowing which are "a" and "b", is to substitute values into the formula given at the beginning of this explanation, as following:

[tex]c=\sqrt{4^2+3^2}[/tex]

Finally, evaluating, you get that "c" is:

[tex]c=\sqrt{16+9}\\\\c=5[/tex]

The magnitude of the resultant vector a and b is 5.

The magnitude of the resultant vector a and b can be found using the Pythagorean theorem.

The Pythagorean theorem states that the magnitude of the resultant vector is equal to the square root of the sum of the squares of its individual vector components.

Let's assume vector a has a magnitude of 3 and vector b has a magnitude of 4. First, we square the magnitude of each vector: a^2 = 3^2 = 9 and b^2 = 4^2 = 16.

Then, we sum the squared magnitudes: a^2 + b^2 = 9 + 16 = 25. Finally, we take the square root of the sum: magnitude of the resultant vector = sqrt(25) = 5. So, the magnitude of the resultant vector a and b is 5.

Answer:

C

Step-by-step explanation:

The equation y = x + 2 does not match these data points either. So, option D is not the correct answer.

Let's analyze each option:

A. y = -2x - 2

This equation represents a linear relationship with a slope of -2 and a y-intercept of -2. It does not seem to match the given data points.

B. -2

This is not an equation, so it cannot be a solution.

C. y = 8 + 2x, y = x + 1

The first equation, y = 8 + 2x, represents a linear relationship with a slope of 2 and a y-intercept of 8.

The second equation, y = x + 1, also represents a linear relationship with a slope of 1 and a y-intercept of 1.

Now, let's check if these equations match the given data points:

Data points: (X, Y) = (0, 0), (0, -4), (0, -2), (0, -4), (0, 0), (0, -1), (0, 2), (0, 6), (0, -6), (0, -1), (0, 2)

None of the equations in option C match these data points. So, option C is not the correct answer.

. y = x + 2

This equation represents a linear relationship with a slope of 1 and a y-intercept of 2.

Now, let's check if this equation matches the given data points:

Data points: (X, Y) = (0, 0), (0, -4), (0, -2), (0, -4), (0, 0), (0, -1), (0, 2), (0, 6), (0, -6), (0, -1), (0, 2)
