Answer 1

Answer:

1) Yes, table shows a probability distribution

2) Mean = 1.5

3) Standard Deviation = 1.1

Step-by-step explanation:

PART 1:

For the table to show a probability distribution, the sum of all probabilities should be equal to 1

Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025

Sum of probabilities = 1

Hence, the table shows the probability distribution.

PART 2:

The formula for mean is given by:

Mean = Sum of terms/ Total no. of terms

Mean = (0+1+2+3) / 4

Mean = 1.5

PART 3:

The formula for standard deviation is given by:

[tex]\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}[/tex]

Solve using a calculator, we get

σ = 1.118

Round off to one decimal place

σ = 1.1

David has a $100 gift card and spends $6 a day. What is x, the number of days that need to pass for Daniel to have the same amount of money on his gift card as David?

Answers

Answer:

Option C is correct

Step-by-step explanation:

Given: inequality is [tex]50-3.50x>100-6x[/tex]

To find: situation that can be represented by the given inequality

Solution:

Cost of Dunkin Donuts gift card with Daniel = $50

Amount spent by Daniel per day = $3.50

Cost of Dunkin Donuts gift card with David = $100

Amount spent by David per day = $6

Amount left with Daniel after x days = [tex]\$(50-3.50x)[/tex]

Amount left with David after x days = [tex]\$(100-6x)[/tex]

According to question,

Amount left with Daniel after x days > Amount left with David after x days

[tex]50-3.50x>100-6x[/tex]

So, he inequality that satisfies the situation is [tex]50-3.50x>100-6x[/tex]

What are the solutions to the expression 4x2+11x−3

Answers

Step-by-step explanation:

4x² + 11x - 3 = 0

(4x-1)(x+3) = 0

x = 1/4, -3

Answer:

x = -3 or x = 1/4

Step-by-step explanation:

Please see the graph in the attachment.

4 x^2 + 11 x - 3= 0

4 (x + 3) (x - (1/4)) = 0

(x + 3)= 0 or (x - (1/4))= 0

x = -3 or x = 1/4

An art teacher needs to buy at least 60 brushes for her class. The brushes are sold in packs of 8. In which inequality does n represent the minimum number of packs the teacher needs to buy for her class?

Answers

Answer:

I think 8n >_ 60

Im not sure but thats what i put

Step-by-step explanation:

The inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

What is Inequality?

Inequality is an expression or statement of an order relationship, which involves the use of inequality signs, variables, numbers and/or algebraic expressions.

Thus:

n = number of brushes in a pack

The teacher must buy 60 brushes and above.

Thus:

8n ≥ 60 will represent the minimum number of brushes for the class.

Therefore, the inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

(08.01) Line H is represented by the following equation: 2x + 2y = 8 What is most likely the equation for line K so the set of equations has infinitely many solutions? x + 2y = 2 x + y = 4 2x + y = 6 x − y = 8

Answers

Answer:

The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)

Step-by-step explanation:

We need to look for the equation that exactly matches the given one :

2 x + 2 y = 8

notice dividing both sides of this equation by "2" we get:

x + y = 4

SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

Used the method of a mathematical expression,

Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, simplify all the expressions for mathematical form as,

a) The difference between twice the product of a and b and the quotient of these numbers.

Here, twice the product of a and b is,

2 × (ab)

And, the quotient of these numbers is,

a/b

Hence, it can be written as,

[tex]2ab - \dfrac{a}{b}[/tex]

b) The sum of squares of c and d increased by twice their product.

Here, d increased by twice their product is,

d + 2cd

And, The sum of squares of c and d increased by twice their product is,

c² + (d + 2cd)

c) The sum of a number c and its square is,

c + c²

d) Now, the number that is 1 greater than a number b is,

1 + b

And the number that is twice as large as b,

2b

So, The quotient of the numbers,

(1 + b)./2b

e) Now, The product of two numbers, p, and q is,

p × q

And, it is decreased by three times their sum:

p × q - 3 (p+q)

pq - 3 (p + q)

find the x in the triangle

Answers

Answer:

20

Step-by-step explanation:

Because this is a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2.  a and b are your legs and c is your hypotenuse, so you have 21^2 + b^2 = 29^2. This equals to 441 + b^2 = 841. subtract 441 from both sides and you are left with b^2 = 400. take the square root of both sides to get your answer b = 20, or x = 20.

Answer:

x = 20

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this:

[tex]a^2 +b^2=c^2[/tex]

→The "a," and "b," are the legs, 21 and x, while the "c," is the hypotenuse, 29. In this case, we are trying to find the value of a leg:

[tex]21^2+b^2=29^2[/tex]

[tex]441+b^2=841[/tex]

→Subtract 441 from both sides:

[tex]b^2=400[/tex]

→To get "b," by itself, you must take the square root of both sides, like so:

[tex]\sqrt{b^2} =\sqrt{400}[/tex]

[tex]b = 20[/tex]
