Alex rolls a six-sided number cube 570 times. Approximately how many times can he expect to roll a 5?

Answers

Answer:

95 times

Step-by-step explanation:

Probability of rolling a 5 =1/6

So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times

1)First determine the probability of rolling a 5

2)Since you can only roll a 5 once in a 6-sided cube the probability is ⅙ or about 0.1667

3)Multiply the probability and the total number of rolls

.1667 * 570= 95

There are two options for buying crickets option A.7 pounds of crickets for 3.15 option B.3 pounds of crickets for 1.47 which option is better to buy justify your answer

Answers

Answer: 7

pounds for 3.15 is a better option

Step-by-step explanation:

Here in this question, we want to know which of the two options is a better option for buying crickets.

To know the better option, we shall be needing the unit price in whatever system to be used;

7 pounds of crickets for 3.15;

so the unit price here will be 3.15/7 = 0.45 per pound

For the second system, we have 3 pounds for 1.47 so the unit price will be 1.47/3 = 0.49 per pound

As we can see, the first option commands a cheaper price per unit, so it is the better option to buy

What is the factored form of this expression? 5p^3-10p^2+3p-6​

Answers

Answer:

[tex](5p^2+3)(p-2)[/tex]

Step-by-step explanation:

In this problem, we need to write the factor form of expression [tex]5p^3-10p^2+3p-6[/tex].

It can be done as follows :

[tex]5p^3-10p^2+3p-6=(5p^3+3p)+(-10p^2-6)[/tex]

Taking common form the terms as follows :

[tex]=p(5p^2+3)-2(5p^2+3)[/tex]

It can be also written as :

[tex]=(5p^2+3)(p-2)[/tex]

Hence, the factored form of [tex]5p^3-10p^2+3p-6[/tex] is [tex](5p^2+3)(p-2)[/tex]

x = -17/5 (Fraction form) x = -3.4

In fraction form the answer is X equals to negative 17 divided by 5 (x = -17/5)

In decimal form the answer is X equals to negative 3 point 4 (x = -3.4)

After solving the equation, the value obtained for x will be equal to -17/5.

What is an equation?

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

List the first 4 terms of the sequence. f(1) = 7, f(n) = f(n-1)+4

Answers

Answer:

7, 11, 15, 19

Step-by-step explanation:

Using the recursive rule with f(1) = 7 , then

f(2) = f(1) + 4 = 7 + 4 = 11

f(3) = f(2) + 4 = 11 + 4 = 15

f(4) = f(3) + 4 = 15 + 4 = 19

The first 4 terms are 7, 11, 15, 19

New York City has a population of 8.55 million and 300 square mile. Manhattan has 1.64 million and 23 square miles. How much greater is the population of Manhattan than New York City?

Answers

Given :

New York City has a population of 8.55 million and 300 square mile area .

Manhattan has 1.64 million and 23 square miles area .

To Find :

How much greater is the population density of Manhattan than New York City.

Solution :

Population density of New York City :

[tex]D_{NY}=\dfrac{8.55}{300}=0.029 \ million/mile^2\\\\D_{M}=\dfrac{1.64}{23}=0.071 \ million/mile^2[/tex]

Now ,

[tex]D_{M}-D_{NY}\\\\(0.071-0.029)=0.042\ million/miles^2[/tex]

Therefore , population density of Manhattan is [tex]0.042\ million/miles^2[/tex] greater than New York City .

Hence , this is the required solution .

A water tank holds 486 gallons but leaking at a rate 4 gallons per week. A second water tank holds 648 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the 2 tanks? The amount of water that holds the two tanks will be the same in _ weeks.

Answers

The first tank contains

486 gal - (4 gal/week) t

gal of water after t weeks.

Similarly, the second tank contains

648 gal - (7 gal/week) t

gal of water.

The tanks hold the same amount of water when these two amounts are equal:

486 gal - (4 gal/week) t = 648 gal - (7 gal/week) t

(7 gal/week) t - (4 gal/week) t = 648 gal - 486 gal

(3 gal/week) t = 162 gal

t = (162 gal) / (3 gal/week)

t = 54 weeks

Solve for n. 11(n – 1) + 35 = 3n

Answers

11n - 11 + 35 = 3n

8n = - 24

n = - 3

Answer:

n = -3

Step-by-step explanation:

Simplifying

11(n + -1) + 35 = 3n

Reorder the terms:

11(-1 + n) + 35 = 3n

(-1 * 11 + n * 11) + 35 = 3n

(-11 + 11n) + 35 = 3n

Reorder the terms:

-11 + 35 + 11n = 3n

Combine like terms: -11 + 35 = 24

24 + 11n = 3n

Solving

24 + 11n = 3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.

24 + 11n + -3n = 3n + -3n

Combine like terms: 11n + -3n = 8n

24 + 8n = 3n + -3n

Combine like terms: 3n + -3n = 0

24 + 8n = 0

Add '-24' to each side of the equation.

24 + -24 + 8n = 0 + -24

Combine like terms: 24 + -24 = 0

0 + 8n = 0 + -24

8n = 0 + -24

Combine like terms: 0 + -24 = -24

8n = -24

Divide each side by '8'.

n = -3

Simplifying

n = -3

At a grocery store, Rick bought 4 loaves of bread and 3 gallons of milk for $20. Danny bought 6 loaves of bread and 2 gallons of milk for $25. Identify the cost of a loaf of bread and a gallon of milk

Answers

Hey there! I'm happy to help!

Let's call the cost of a bread loaf b and the cost of a milk gallon m. Here is the info we have.

4b+3m=20

6b+2m=25

We solve one equation for b or m (we will solve the first one for b.

4b+3m=20

Subtract 3m from both sides.

4b=20-3m

We divide both sides by 4.

b=5-3/4m

We plug this value of b into the second equation to solve for m.

6(5-3/4m)+2m=25

We use distributive property to undo the parentheses.

30-4.5m+2m=25

We combine like terms.

30-2.5m=25

We subtract 30 from both sides.

-2.5m=-5

We divide both sides by -2.5

m=2

We plug this m into one of the original equations to find b.

4b+3(2)=20

4b+6=20

Subtract 6 from both sides.

4b=14

Divide both sides by 4.

b=3.5

So, a loaf of bread costs $3.50 and a gallon of milk costs $2.00.
