HELP ME BABES!!!
Use the equation below to find P, (P=a+b+c)
if =a13, =b17, and =c7

Answer:

ƒ(x) = 3|x – 2| + 1

To find f(-2) substitute - 2 into f(x)

That's

f(-2) = 3| - 2 - 2 | + 1

= 3| - 4| + 1

But absolute value of any number is positive including negative numbers

That's

| - 4 | = 4

So we have

3(4) + 1

12 + 1

To find f(1) substitute 1 into f(x)

That's

f(1) = 3 | 1 - 2| + 1

= 3 | - 1| + 1

But | - 1| = 1

= 3(1) + 1

= 3 + 1

Hope this helps you

Answer:

f(-2) =13

f(-1) = 4

Step-by-step explanation:

ƒ(x) = 3|x – 2| + 1

Let x = -2

ƒ(-2) = 3|-2 – 2| + 1

       = 3 | -4| +1

Taking the absolute value

    = 3*4 +1

    = 12 +1 = 13

Let x = 1

ƒ(1) = 3|1 – 2| + 1

       = 3 | -1| +1

Taking the absolute value

    = 3*1 +1

    = 3 +1 = 4

The margin of error with a 99% confidence level for the data is approximately 17.06 and  a range of 508 ± 17.06, or between 490.94 and 525.06.

What is margin error ?

Margin of error is a statistical term that refers to the range of error that is inherent in any sample-based estimation of a population parameter. It is typically used in the context of opinion polls, surveys, and other types of data collection that involve taking a sample of a larger population.

The margin of error represents the degree of uncertainty that is associated with the sample estimate, and it is influenced by factors such as the size of the sample, the variability of the data, and the desired level of confidence in the estimate.

According to the question:

To calculate the margin of error with a 99% confidence level, we can use the following formula:

Margin of error = z* (standard deviation / sqrt(sample size))

where z* is the critical value for a 99% confidence level, which can be found using a standard normal distribution table or calculator. For a 99% confidence level, the critical value is approximately 2.576.

Given that the mean score on the exam was 508 with a standard deviation of 121 and a sample size of 200, we can plug these values into the formula to find the margin of error:

Margin of error = \(2.576 * (121 / \sqrt{200})\)

≈ 17.06

Therefore, the margin of error with a 99% confidence level for the data is approximately 17.06. This means that we can be 99% confident that the true mean score on the exam falls within a range of 508 ± 17.06, or between 490.94 and 525.06.

Answer:-4x^2-2x+46.

Step-by-step explanation:

To simplify this expression, you can start by distributing the negative sign to the first set of parentheses:

(-3)(x+4)(x-6)-(x^2+8x-10)

Then, you can distribute the -3 to the terms inside the first set of parentheses:

(-3x-12)(x-6)-(x^2+8x-10)

Then, you can combine like terms:

-3x^2+6x+36-x^2-8x+10

This simplifies to:

-4x^2-2x+46

Therefore, the expression that is equivalent to -3(x+4)(x-6)-(x^2+8x-10) is -4x^2-2x+46.

Answer:

8

Step-by-step explanation:

Substitute the values in the expression, we have:

\(\displaystyle{|-1-3|+4}\)

Evaluate:

\(\displaystyle{|-4|+4}\)

Any real numbers in the absolute sign will always be evaluated as positive values. Thus:

\(\displaystyle{|-4|+4 = 4+4}\\\\\displaystyle{=8}\)

Hence, the answer is 8. A quick note that z-value is not used due to lack of z-term in the expression.

The function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

Transformation techniques

Transformation is the process of changing the position of an object on the xy-plane.

Given the parent function

f(x) = 4x

If the function is not reflected over x-axis, the resulting function will be f(x) = -4x

If the resulting function is compressed by a factors of 1/8, hence the final function rule will be;

g(x) = 1/8(-4x)

g(x) = -1/2x

Hence the function rule g(x) after the given transformations of the graph of f(x)=4x is g(x) = -1/2x

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

Answer:

166 marbles

Step-by-step explanation:

O - 44 = L

O - 48 = J

O - 6 = L + J

I want to isolate O here

O = 44 + L

Plug it in

44 + L - 6 = L + J

38 + L = L + J

38 = J

Now we know that Jack has 38.

O - 48 = J

O - 48 = 38

O = 86

Now we know Oscar has 86.

O - 44 = L

86 - 44 = L

42 = L

Lily has 42.

38 + 86 + 42 = .....166

They have 166 coins altogether - Also Happy New Year!!! :D

Answer:

b; 166 coins

Step-by-step explanation:

let o = oscar

let l = lily

let j = jack

o = l + 44

o = j + 48

o = l + j + 6

you can combine the first 2 equations together using substitution

l + 44 = j + 48

then reorder the 3rd to have l in front

-l = -o + j + 6 -->

l = o - j - 6

o - j - 6 + 44 = j + 48

then simplify the equation down

o = 2j + 10

then use the 2nd equation as substitution for o

j + 48 = 2j + 10

simplify

j = 38

finally you find o and l

38 + 48 = o --> o = 86

86 = l + 44 --> l = 42

last but not least you add them together

38 + 86 + 42 = 166

It took Ringani 2.8 years  to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into the account with a 7.04% interest rate Compounded annually.The correct answer choice is C. 2.8 years.

To determine how long it took Ringani to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into an account with a 7.04% interest rate compounded annually, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount

P is the principal amount (initial deposit)

r is the interest rate (in decimal form)

n is the number of times the interest is compounded per year

t is the time in years

In this case, we have:

P = R8,500.00

A = R30,000.00

r = 7.04% = 0.0704 (in decimal form)

n = 1 (compounded annually)

We want to find the value of t.

Using the formula, we can rearrange it to solve for t:

t = (log(A/P)) / (n * log(1 + r/n))

Substituting the given values, we have:

t = (log(30,000/8,500)) / (1 * log(1 + 0.0704/1))

Calculating this using a calculator, we find that t is approximately 2.8 years.

Therefore, it took Ringani approximately 2.8 years (rounded to one decimal place) to accumulate the total amount of R30,000.00 by depositing R8,500.00 yearly into the account with a 7.04% interest rate compounded annually.

The correct answer choice is C. 2.8 years.

The required probability of drawing a red marble from the bag and any specific card from the deck is 1/156.

There are 12 marbles in the bag, and 4 of them are red, so the probability of drawing a red marble is 4/12, or 1/3.

There are 52 cards in the deck, and the probability of drawing any specific card is 1/52.

This probability assumes that the events are independent, meaning that the outcome of one event does not affect the outcome of the other event.

In this case, drawing a marble from the bag and drawing a card from the deck are independent events, so their probabilities can be multiplied.

Therefore, the probability of drawing a red marble from the bag and any specific card from the deck is (1/3) x (1/52) = 1/156.
