The given points can only be represented by an exponential function.

A linear function has the following form = y = f(x) = a bx

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

a is a constant term or y-intercept. This is the value of the dependent variable when x = 0.

b is the coefficient of the independent variable. It is also called the slope and gives the rate of change of the dependent variable.

 We can determine the type of function that can represent the given points by looking at the pattern of y values ​​corresponding to the x values.

Linear Function: A linear function has a constant slope, which means that the difference between any two consecutive values ​​of y must be the same as the difference between  two consecutive values ​​of x. The difference between  two consecutive y values ​​is 9/8, which is not the same as the difference between  two consecutive x values ​​(which is 1). Therefore, the given points cannot be represented by a linear function.  Exponential function: an exponential function has a constant ratio between  two consecutive y-values, meaning that the ratio of any two consecutive y-values ​​must be the same as the ratio of any two consecutive x-values.

The ratio of  two consecutive y values ​​is 2, which is the same as the ratio of  two consecutive x values ​​(which is 1/2). Therefore, the given scores can be represented by an exponential function.  Quadratic function: A quadratic function has a quadratic term, which means that the y-values ​​should show an increasing or decreasing pattern of differences between successive x-values.  The differences between successive y values ​​are 9/8, 3/8, 1/2, and 9. There is no  pattern of increasing or decreasing differences between successive x values, so the given points cannot be represented by a square. function

Therefore, the given scores can only be represented by an exponential function.

Answer:

The probability of selecting an orange chew is 25/62, and the probability of selecting a peach chew is 13/62. To find the probability that the next chew Lydia removes from the bag will be orange or peach, we add these probabilities:

P(orange or peach) = P(orange) + P(peach) = 25/62 + 13/62 = 38/62

To express this probability as a percent, we divide the numerator by the denominator, then multiply by 100:

P(orange or peach) = 38/62 = 0.6129...

0.6129... × 100 ≈ 61

Therefore, the probability that the next chew Lydia removes from the bag will be orange or peach, expressed as a percent to the nearest whole number, is 61%

[tex]\frac{3}{12} =\frac{1}{4}[/tex] answer

We have,

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

The probability that at least three out of five randomly selected students will possess a GPA in excess of 3.0 is approximately 0.1772.

To solve this problem, we need to use the binomial distribution with n = 5 and the probability of success p = P(GPA > 3.0), which can be found using the normal distribution table:

P(GPA > 3.0) = P(Z > (3.0 - 2.7)/0.7) = P(Z > 0.43) = 1 - P(Z < 0.43) = 1 - 0.6664 = 0.3336

Now we can use the binomial distribution to find the probability that at least three students out of five have a GPA greater than 3.0:

P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5)

Using the binomial formula and the probabilities of success and failure:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

we get:

P(X = 3) = (5 choose 3) * 0.3336^3 * 0.6664^2 = 0.1311

P(X = 4) = (5 choose 4) * 0.3336^4 * 0.6664^1 = 0.0421

P(X = 5) = (5 choose 5) * 0.3336^5 * 0.6664^0 = 0.0040

Therefore:

P(X ≥ 3) = 0.1311 + 0.0421 + 0.0040 = 0.1772

So the probability that at least three out of five students have a GPA greater than 3.0 is approximately 0.1772.

The product of the factors of [tex]65x^2 + 212x - 313[/tex] is equal to the original expression. Lauren may have recognized the expression as a difference of squares and factored it accordingly.

We can first simplify the expression [tex]65x^2 + 212x - 313[/tex] by factoring it:

[tex]65x^2 + 212x - 313 = (13x - 1)(5x + 313)[/tex]

(13x - 1)(5x + 313) = [tex]65x^2 + 212x - 313[/tex]

Therefore, the product of the factors is equal to the original expression.

To see this, we can rewrite the expression as:

[tex]65x^2 - 313 - 212x = (5x)^2 - (2\cdot 5x \cdot 7) + 7^2 - 7^2 - 212x[/tex]

= [tex](5x - 7)^2 - 7^2 - 212x[/tex]

= [tex](5x - 7)^2 - 212x - 49[/tex]

= [tex](5x - 7)^2 - 1^2\cdot 49 - 212x[/tex]

= (5x - 7 - 7)(5x - 7 + 7) - 49 = (5x - 14)(5x) - 49

= 5x(5x - 14) - 49

= 5x(5(x - 2) - 9)

= 5x(5x - 29)

Therefore, the factors of the expression are (5x - 7) and (5x - 29).

Lauren may have recognized the expression as a difference of squares by noticing that the coefficient of the x term (212) is twice the product of the square roots of the first and last terms (sqrt(65) and sqrt(313)), which is a common characteristic of a difference of squares.

Answer:

real and rational roots

Step-by-step explanation:

The discriminant of the given equation is [tex]7^2-4(2)(6)=1[/tex].

Since the discriminant is a perfect square, the equation has real and rational roots.

The probability that the mean weight of two fruits picked at random falls between 360 grams and 491 grams is approximately 0.9554 or 95.54%.

To solve this problem, we need to use the formula for the sampling distribution of the sample mean:

x' = μ/√n

where x' is the sample mean, μ is the population mean, and n is the sample size.

Given that the population mean is 443 grams and the standard deviation is 34 grams, we can calculate the standard error of the sample mean:

SE = σ/√n

  = 34/√2

  ≈ 24.04 grams

Now we need to standardize the sample mean to a standard normal distribution using the z-score formula:

z = (x' - μ)/SE

The probability that the sample mean falls between 360 grams and 491 grams is equivalent to the probability that the z-score falls between:

z = (360 - 443)/24.04 ≈ -3.45 and z = (491 - 443)/24.04 ≈ 1.99

Using a standard normal table or calculator, we can find the probability that the z-score falls between -3.45 and 1.99, which is approximately 0.9554.

Step-by-step explanation:

To calculate Heidi's overtime pay, we first need to find out how many hours she worked overtime and then multiply those hours by her overtime pay rate. The standard workweek in the United States consists of 40 hours, and any hours worked beyond 40 hours are considered overtime.

Step 1: Calculate the number of overtime hours:

Total hours worked = 47.50 hours

Standard workweek = 40 hours

Overtime hours = Total hours worked - Standard workweek = 47.50 - 40 = 7.50 hours

Step 2: Calculate Heidi's overtime pay rate:

Hourly wage = $15.85

Overtime pay rate = Hourly wage * 1.5 (overtime is typically paid at 1.5 times the regular hourly rate) = $15.85 * 1.5 = $23.775

Step 3: Calculate Heidi's overtime pay:

Overtime pay = Overtime hours * Overtime pay rate = 7.50 hours * $23.775 = $178.31 (rounded to 2 decimal places)

Heidi's overtime pay for the week is $178.31.

To find the diameter of the Andromeda galaxy in miles, we can use the given information:

Diameter of Andromeda galaxy = 2.2 X 10^5 light-years

1 light-year = 5.9 X 10^12 miles

So, we can use dimensional analysis to convert light-years to miles:

2.2 X 10^5 light-years * 5.9 X 10^12 miles/light-year = 1.298 X 10^18 miles

Therefore, the diameter of the Andromeda galaxy in miles is approximately 1.298 X 10^18 miles.

Thus, the following is the rule for the given geometric sequence: [tex]a = 64 * (-2)^(n-1) (n-1)[/tex]. Thus, the solution is (C) a = 64(-2)n-1.

An structured of integers or objects that adhere to a particular pattern or rule is referred to as a sequence in mathematics. The name for each number or item in the sequence is. A series can be explicitly created or defined recursively, and it can be infinite or finite. A method or rule that directly expresses the n - th term of the series in terms of n defines an explicit sequence. For instance, the explicit sequence 2, 4, 6, 8, 10,... has the formula a = 2n, where n is the term's position inside the sequence. A starting value and recursive formula that determines the nth word of the series in terms of the preceding terms describe a recursive sequence.

given

The number sequence is as follows: 64, -128, 256, -512.

We must determine the common ratio between the following terms in order to get the rule for this sequence.

Any term can be divided by its previous term to obtain the common ratio (r). For instance, the result of subtracting the second term (-128) from the first term (64) is

r = (-128) / 64 = -2

The third term (256) divided by the second term (-128) results in:

r = 256 / (-128) = -2

And when the fourth term (-512) is divided by the third term (256), the result is

r = (-512) / 256 = -2

We can observe that for all pairings of following terms, the common ratio is -2.

Now we can apply the following formula to a geometric sequence's general term:

a = a1 * r^(n-1) (n-1)

where r is the common ratio and a1 is the first term.

In place of the values we hold:

[tex]a = 64 * (-2)^(n-1) (n-1)[/tex]

Thus, the following is the rule for the given geometric sequence: [tex]a = 64 * (-2)^(n-1) (n-1)[/tex]. Thus, the solution is (C) a = 64(-2)n-1.

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x.

a) A quartic function with zeroes -5/2, -1, 7/2, and 3 can be written as the product of linear factors with those zeroes:

f(x) = a(x + 5/2)(x + 1)(x - 7/2)(x - 3)

where "a" is a constant that determines the overall scaling of the function.

b) Two examples of functions that belong to this family are:

f1(x) = 2(x + 5/2)(x + 1)(x - 7/2)(x - 3)

f2(x) = -0.5(x + 5/2)(x + 1)(x - 7/2)(x - 3)

Note that these functions differ only in the value of the constant "a".

c) To find the value of "a" that makes the graph of the function pass through the point (-2,25), we can substitute x = -2 and y = 25 into the equation for f(x):

25 = a(-2 + 5/2)(-2 + 1)(-2 - 7/2)(-2 - 3)

Simplifying this expression:

25 = a(5/2)(-1)(-11/2)(-5)

25 = a(6875/4)

a = 100/6875 = 4/275

Therefore, the equation for the member of the family that passes through the point (-2,25) is:
