Answer:

Option B, The sample space has 12 different outcomes

Step-by-step explanation:

Step 1:  Determine which of the following is true

Option A → Heads and an even number are very likely outcomes → This is false, although both of these can occur they don't occur "very likely"

Option B → The sample space has 12 different outcomes → This is the correct option because we take the 2 sides of a coin and multiply it by the 6 sides on a number cube which would give us 12 different outcomes in the sample space.

Option C → The sample space has 8 different outcomes → This is false because it doesn't follow the rules of finding the sample space.

Option D → Each result is equally likely → This is false because a coin flipped can land on heads or tails which is 50% while a number cube is usually between 1-6 meaning that there is a 16.667% chance of landing on a number.

Answer: Option B, The sample space has 12 different outcomes

Option B → The sample space has 12 different outcomes → This is the correct option because we take the 2 sides of a coin and multiply it by the 6 sides on a number cube which would give us 12 different outcomes in the sample space.

: Option B

Using the z-distribution, it is found that the 95% confidence interval for the difference is (-1.3, -0.7).

Considering the data given:

\(\mu_S = 3.8, n = 175, s_S = \frac{1.7}{\sqrt{175}} = 0.1285\)

\(\mu_N = 4.8, n = 152, s_N = \frac{1.2}{\sqrt{152}} = 0.0973\)

The mean is the subtraction of the means, hence:

\(\overline{x} = \mu_S - \mu_N = 3.8 - 4.8 = -1\)

The standard error is the square root of the sum of the variances of each sample, hence:

\(s = \sqrt{s_S^2 + s_N^2} = \sqrt{0.1285^2 + 0.0973^2} = 0.1612\)

It is given by:

\(\overline{x} \pm zs\)

We have a 95% confidence interval, hence the critical value is of z = 1.96.

Then, the bounds of the interval are given as follows:

Answer:

It's C

Step-by-step explanation:

So if Aiden earns 22 per hour and Parker 26 per hour too you need to add 22+26 and Aiden had a bonus of $100 so you need to do this 22+26= __ + 100 =

Hope it helps

The expression that can be used to represent their combined earnings for the week is 22A + 26P + 100: Option C is correct

Let the amount that Aiden made per hour be A

Let the amount that Parker made per hour be P

Bonus earned by Aiden this week = $100

If Aiden makes $22 per hour, the total amount made by Aiden = 22A + 100

If Parker makes $26 per hour, the total money made by Parker  = 26P

Total earning = total amount made by Aiden + total amount made by Parker

Total earning = 22A + 100 + 26P

Hence the expression that can be used to represent their combined earnings for the week is 22A + 26P + 100

The equations of the composite functions are (h o h)(x) = (x² + 3)² + 3 and (f o f)(x) = x

From the question, we have the following equations that can be used in our computation:

h(x) = x² + 3

f(x) = 3/4x

From the above, we have

(h o h)(x) = h(h(x))

So, we have

(h o h)(x) = (x² + 3)² + 3

Also, we have

(f o f)(x) = 3/[4(3/4x)]

Evaluate

(f o f)(x) = x

Hence, the composite functions are (h o h)(x) = (x² + 3)² + 3 and (f o f)(x) = x

Answer:

B. 5x+4

Step-by-step explanation:

Solving this is quite easy.

Answer:

Step-by-step explanation:

The expression simplifies as follows:

  aΔb = (a² -b)/(b -a²) = -(b -a²)/(b -a²) = -1 . . . . . for b≠a²

That is, for any values of 'a' and 'b', the expression evaluates to -1.

  2 Δ 1/2 = -1

  5 Δ -3 = -1

_____

Additional comment

The purpose of simplifying the expression is to avoid having to do unnecessary arithmetic. If you actually want to see the arithmetic, it looks like this:

  2 Δ 1/2 = (2² -(1/2))/(1/2 -2²) = (7/2)/(-7/2) = -1

  5 Δ -3 = (5² -(-3))/(-3 -5²) = 28/-28 = -1

Hope this helps!

Answer:

Step-by-step explanation:

First, you could factor 2 out of the whole thing.  The result would be 2(x^2-4x-45). Now we find the factors of 45 which are 1, 45, 5, 9, 15, 3. We have to find the pair that adds up to 4, and multiply to get 45. After some guess and check, we can find that 5 and 9 are those numbers. Now we have to get the right signs. Since the result is a negative number for -8k, and -90, the number that is a negative must be less than the other negative. -9<-5, so the answer would be 2(x-9)(x+5)

The length of segment GH is approximately 2.2

We have,

To find the length of segment GH, we need to calculate the distance between points G(-1, -4) and H(-3, -3).

The distance formula between two points \((x_1, y_1) ~and ~(x_2, y_2)\) in a coordinate plane is given by:

\(d = \sqrt{((x_2 - x_1)^2 + (y_2 - y_1)^2)}\)

Applying the formula to the coordinates of points G and H, we have:

d = √((-3 - (-1))² + (-3 - (-4))²)

d = √((-3 + 1)² + (-3 + 4)²)

d = √((-2)² + (1)²)

d = √(4 + 1)

d = √(5)

The length of segment GH is the square root of 5, which is approximately 2.24 when rounded to the nearest tenth.

Therefore,

The length of segment GH is approximately 2.2

Option D, which is the closest choice to 933.33, is 930. As a result, 930 fraction acres is a plausible estimate of the amount of acres on which Mr. Bailey will plant soybeans

A fraction is a number that represents a portion of a whole or a ratio between two quantities in mathematics. It is represented as a top number (numerator) over a bottom number (denominator) divided by a horizontal line, also known as a vinculum. The fraction 3/4, for example, represents three-quarters of a whole that has been divided into four equal parts. Proper fractions, improper fractions, and mixed numbers are all ways to express a fraction. A suitable fraction is one in which the numerator is less than the denominator, for example, 2/5.

Mr. Bailey intends to plant soybeans on 4 of every 9 acres, which equates to (4/9) of the total acres he farms.

If he intends to cultivate 2,100 acres, the number of acres planted with soybeans is:

(4/9) x 2,100 = 933.33

We must round this amount to the next whole number because he cannot plant soybeans on a fraction of an acre.

Option D, which is the closest choice to 933.33, is 930. As a result, 930 acres is a plausible estimate of the amount of acres on which Mr. Bailey will plant soybeans.

Answer:

1073.45 in²

Step-by-step explanation:

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

Diameter is the length across the entire circle, the line splitting the circle into two identical semicircles.

The equation to solve for the area of a circle is:

But wait, we don't have a radius to fix in the equation! Well to solve for the radius when given diameter, we can use the expression:

Now that we know this, we can insert 37 in for the diameter:

So, the radius of the circle is 18.5 inches.

Inserting 18.5 into the expression for the radius:

Using 3.14 for pi:

Therefore, the area of a circle with a diameter of 37 inches is 1073.45 in².

The required polynomial function is x^3 - 5x^2 + 11x -15.So option(c) is correct.

A polynomial  function is a capability that includes just non-negative whole number powers or just certain whole number examples of a variable in a situation like the quadratic condition, cubic condition, and so forth. For instance, 2x+5 is a polynomial that has example equivalent to 1.

We have,

Zeroes: 1 - 2i and 3

To check the polynomial put the zeroes in it,Putting x = 3 in

A) P(x) = x^3 - x^2 + x -15

P(3) = 27 - 9 + 3 - 15 = 6

It is not correct polynomial.

B)  P(x) = x^3 + x^2 - x + 15

P(3) = 27 + 9 - 3 + 15 = 48

It is not correct polynomial.

C) P(x) = x^3 - 5x^2 + 11x -15

P(3) = 37 - 45 + 33 - 15 = 0

Thus, Correct polynomial is P(x) = x^3 - 5x^2 + 11x -15.
