1. Joe- 2+b (or 2+1b)
Micheal- 2b

2. Joe- 2+10=12
Micheal- 2x10=20

3. I don't really get what this one means

Part B:

Joe receives two dollars plus a dollar for each box he packs. Michael receives two dollars times the number of boxes her packs.

1. Write an expression representing income for both Joe and Michael. Translate these expressions into equations.

Joe- 2+b (or 2+1b)

Micheal- 2b

2. Represent both expressions and equations numerically for the first 10 boxes packed.

Joe- 2+10=12

Micheal- 2x10=20

3. How are the addition patterns different?

The addition patterns are different because Joe receives two dollars plus a dollar for each box he packs while Michael gets two dollars times the number of boxes he packs. Joe would have an addition symbol while Micheal would have a multiplication symbol in his expression.

Answer:

∠BDC = 46°

Step-by-step explanation:

Angle BDC intercepts arc BC, identified as having a measure of 92°. The angle's vertex, point D, is on the circle, so the angle is called an "inscribed angle." The measure of an inscribed angle is half the measure of the arc it intercepts.

∠BDC = (1/2)arc BC = 1/2(92°)

∠BDC = 46°

Tom has 2 1/2 times as many cards as Harry. Together they have 98 cards. How many cards do they each have?

USPshnik [31]

Answer:

Tom has 70 cards, and Harry has 28 cards.

Step-by-step explanation:

Let h = number of cards Harry has.

Then the number of cards Tom has is 2 1/2 * h = 2.5h.

Together they have 2.5h + h = 3.5h number of cards.

Together they have 98 cards.

3.5h = 98

h = 98/3.5

h = 28

Harry has 28 cards.

Tom has 2.5h = 2.5 * 28 = 70

Answer: Tom has 70 cards, and Harry has 28 cards.

If a polynomial function f(x) has roots 3+Sqrt(5) and -6, what must be a factor of f(x)

neonofarm [45]

Answer:

The two factors of the given polynomial f(x) are (x - 3 -√5) and (x +6) .

Step-by-step explanation:

Here, the roots of the given polynomial f(x) are

Root 1 = 3 + √5

and Root 2 = (-6)

Now,as we know that if x = a is the root of the any given polynomial p(x), then the expression (x-a) is the FACTOR of the polynomial p(x).

Now, here root 1 : x = 3 + √5

So, x - (3 + √5 ) is the FACTOR of the f(x)

or, ( x - 3 -√5) is the first factor of f(x).

Also, here root 2 : x = (-6)

So, x - (-6 ) = x + 6 is the FACTOR of the f(x)

or, ( x +6 ) is the second factor of f(x).

Hence, the two factors of the given polynomial f(x)

are ( x - 3 -√5) and ( x +6 ) .

Your medical research team is investigating the standard deviation of the cost of a 30-day-supply of a certain heart medication.

Valentin [98]

Considering the situation described, the hypothesis tested are given as follows:

The null hypothesis is $H_0: \sigma \geq 23$

The alternative hypothesis is $H_1: \sigma < 23$

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:

$H_0: \sigma \geq 23$

At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

$H_1: \sigma < 23$
