Answer:

The expressions are equivalent.

Step-by-step explanation:

Let's simplify each expression.

6(3x + 1) = 18x + 6

9x + 6 + 9x = 18x + 6

Both expressions are equal to 18x + 6, so they are equivalent.

Answer: The expressions are equivalent.

Answer: $2.40

Work: So to find the markup price, you multiply the price by the markup, so the equation is going to be $1.50 x .60 (Remember, Markup and tax, you move the decimal two spots over) After the equation, you get $0.90. Add 90 cents to $1.50, and you get $2.40 (The Selling price with the markup) I hope this helps, and stay safe! :)

Answer:

The new selling price is $2.40

Step-by-step explanation:

1. First we need to convert 60% into a decimal, which is 0.60.

2. Now we need to multiply $1.50 and 0.60, so 1.50 × 0.60 = 0.90.

They added $0.90 to the can, now we need to add $1.50 and $0.90, which is $2.40.

Answer:

a=13 b=13

Step-by-step explanation:

Because the triangles are congruent, their corresponding angles will be congruent, too.

So, ∠Y≅∠S  and ∠Z≅∠T.

Set the values of these angles equal to each other and solve.

∠Y≅∠S               ∠Z≅∠T

4a-4= 48                5b-3= 62

4a=52                    5b= 65

a=13                        b= 13

9 invitations

Explaination:

3/4 of an hour is 45 minutes

1/12 of an hour is 5 minutes

This means she has 45 mins to make invitation and she can make 1 invitation in 5 mins

45÷5=9

this means she can make 9 invitations in 45 mins

Given:

The inequality is

[tex]9x+9>12x+6[/tex]

To find:

The mistake in the given solution and correct it.

Solution:

We have,

[tex]9x+9>12x+6[/tex]

Isolating variable on one side, we get

[tex]9x-12x>6-9[/tex]

[tex]-3x>-3[/tex]

On dividing both sides by -3,  we get

[tex]\dfrac{-3x}{-3}<\dfrac{-3}{-3}[/tex]

Because if an inequality is multiplied or divided by a negative number, then the sign of inequality must be changed.

[tex]x<1[/tex]

Therefore, there is a mistake in last step because the sign of inequality remains same after diving it by -3 and the correct solution is [tex]x<1[/tex].

Step-by-step explanation:

The problem can be written as

Ar = where A = 5×6 matrix. dim(NullA)=1 as  all the multiples of Ar=0

are the multiple of one non zero solution.

Since A is 5×6 , A n= 6

rank(A)= n-dim(Nul A)= n-1= 6-1=5

now, imagine A as 5 dimensional subspace of R^5( As  A has 5 rows)

Therefore Col(A)= R^5

This means that Ar = b has a solution for every b.

Answer:

Find the graph attached

Step-by-step explanation:

The standard form of equation of as line is expressed as y = mx+c

m is the slope

c is the intercept

Given the equation;

y=0.05x+2,500

slope m = 0.05

y-intercept c  = 2500

Get the x intercept.

when y = 0

0 = 0.05x + 2500

-0.05x = 2500

x = -2500/0.05

x = 50,000

The x-intercept is 50,000

To graph the function, we will locate the x coordinate and the y coordinate on the graph as shown below;

Using the scale:

2cm represent 10,000 units on x axis

2cm represent 1,000 units on y axis

Answer:

{-2, 8, -5, -2, 7}

Step-by-step explanation:

The domain is the set of input variables in a relation. In most cases, x represents the input variables, and y represents the output variables. Therefore, the domain is the set of numbers under the column x.

Answer: a= 0.0231

Step-by-step explanation:

n=8

p=0.75

q=1 - 0.75 = 0.25

(p=x)

p(5) = 8C5 (0.25)^5 (0.75)^8-5

p(5)= 0.0231

Or 2.31%

The probability that exactly 3 people  from that group will go to Ches Tahoe restaurant is 2.11%

The probability that at least 35 people will go to Ches Tahoe  the restaurant is -1.88.

Given that,

When you select a random person, the probability that this person will go to Ches Tahoe restaurant is 75%,

We have to determine,

You randomly select 8 people. What is the probability that exactly 3 people

from that group will go to Ches Tahoe restaurant.

You randomly select 50 people. Use the normal approximation to the binomial distribution to find the probability that at least 35 people will go to Ches Tahoe restaurant.

According to the question,

When you select a random person, the probability that this person will go to Ches Tahoe restaurant is 75%,

You randomly select 8 people.

Then,

The probability that exactly 3 people

from that group will go to Ches Tahoe restaurant is,

[tex]P(x) = ^nC_x \times q^x \times p^{n-x}[/tex]

Where n = 8, x = 5, q = 1 - 0.75 = 0.25, and p = 0.75

Substitute all the values in the expression,

[tex]P(5) = ^8C_5 \times (0.25)^5 \times (0.75)^{8-5}\\\\P(5) = \dfrac{8!}{(8-5)!. 5!} \times 0.00097 \times (0.75)^3\\\\P(5) = \dfrac{8 \times 7 \times 6}{3 \times 2} \times 0.00097 \times 0.42\\\\P(5) = 0.2118\\\\P(5) = 2.11 \ Percent[/tex]

The probability that exactly 3 people from that group will go to Ches Tahoe restaurant is 2.11%.

You randomly select 50 people. Use the normal approximation to the binomial  distribution

Then, the probability that at least 35 people will go to Ches Tahoe  restaurant is,

Mean for that at least 35 people will go to Ches Tahoe  restaurant is,

[tex]\mu = n \times p \\\\\mu = 8 \times 0.75\\\\\mu = 6[/tex]

And standard deviation that at least 35 people will go to Ches Tahoe  restaurant is,

[tex]\sigma = \sqrt{n \times p \times q} \\\\\sigma = \sqrt{0.75 \times 0.25 \times 8}\\\\\sigma = \sqrt{1.5}\\\\\sigma = 0.53[/tex]

Normal approximation to the binomial distribution is,

[tex]z = \dfrac{x-\mu}{\sigma}\\\\z = \dfrac{5-6}{0.53}\\\\z = \dfraac{-1}{0.53}\\\\z = -1.88[/tex]

The probability that at least 35 people will go to Ches Tahoe  the restaurant is -1.88.

Slope m = 1

Point (1, 4)

Answer:

y-5=2(x-4)

Step-by-step explanation:

Considering the slope intercept form is  y=2x+9 and the point is (4,5), you would just need to plug in all the necessary numbers in point-slope form.

Point-slope form:

y-y1=m(x-x1) → y-5=2(x-4)

m represents the slope, which is 2 in this situation.

y1 represents the y coordinate, which is 5 in this situation.

x1 represents the x coordinate, which is 4 in this situation.
