Answer 1

Answer:

25

Step-by-step explanation:

if X = 4 then you would do

4(4) + 9

since 4 x 4 is 16

add that by 9

16 + 9 = 25

so the value of 4x + 9 = 25

Hope this helps

the cost of fun for kids magazine for x number of months is shown below

The cost (C) of another magazine, Family Fun, for x number of months is
given by C-1.99x.

The cost of another magazine, Kidz Comics, is $1.85 for each month. The
annual subscription includes a delivery charge of $10, while the annual
subscription for Fun for kids and Family Fun has no such extra charge
Which annual subscription costs the most?​

Answers

Answer:

Kidz comic costs the most

Step-by-step explanation:

Given

Family Fun

[tex]C(x) = 1.99x[/tex]

Kidz Comics

[tex]m = 1.85[/tex] --- monthly rate

[tex]b = 10[/tex] --- delivery charge

Required

Which is more expensive

A linear function is represented as:

[tex]f(x) = mx + b[/tex]

Where

[tex]m = rate[/tex]

[tex]b = y\ intercept[/tex] --- i.e. the base charge

So, for Kidz comic; We have:

[tex]f(x) = mx + b[/tex]

[tex]C(x) = 1.85x + 10[/tex]

To calculate the annual cost, we set x = 12; i.e. 12 months.

So, we have:

[tex]C(x) = 1.99x[/tex] ---- Family Fun

[tex]C(12) = 1.99 * 12[/tex]

[tex]C(12) = 23.88[/tex]

[tex]C(x) = 1.85x + 10[/tex] --- Kidz comic

[tex]C(12) = 1.85*12 + 10[/tex]

[tex]C(12) = 22.2 + 10[/tex]

[tex]C(12) = 32.2[/tex]

By comparison

[tex]32.2 > 23.88[/tex]

Hence, Kidz comic is more expensive

What is m
A: 19°
B: 68°
C: 112°

Answers

Answer:

m<N=68

Step-by-step explanation:

opposite angles of the parallelogram are equal(or congruent):

4x+36=6x-2

6x-4x=36+2

2x=38

x=38/2=19

the sum of the angles of the parallelogram =360

4x+36=4(19)+36=112 angle P

6x-2=6(19)-2=112 angle M

let Q= N=x

2x+112+112=360

2x=360-224

2x=136

x=136/2=68

A marble is picked at random. Without putting the first marble back, a second marble is picked at random. ​Find the probability that first marble picked is green and second marble picked is red. ​Write your result as a percentage.

Answers

Answer:

Probability = 1/5 = 20%

Step-by-step explanation:

Prob (1st marble green) = Green Marbles / Total Marbles = 3/6 = 1/2

Pr (2nd marble red), without replacement = Red Marbles / Left Total Marbles = 2/5

Prob (1st marble green, & 2nd marble red) = 1/2 x 2/5 = 1/5

Prob in percent = 1/5 x 100 = 20%

(31 points) Wilson County School District consists of 2,548 students. The district decided to conduct a survey regarding their new dress code policy. Wilson County School District surveyed 479 of their students and found that 42% of those surveyed disliked the new dress code policy. What is the margin of error, assuming a 95% confidence level?

Answers

Answer:

+ or - 0.044

Step-by-step explanation:

The margin of error is 0.044.

What is a Margin of Error?

A Margin of Error is defined as the results will vary from the actual population value by how many percentage points, as indicated by the margin of error.

The margin of error using this formula, where z is the critical value.

[tex]ME = z\sqrt{\dfrac{T(1 - t)}{n} }[/tex]

To determine a margin of error for a sample proportion,

Where n is the sample size and is the sample proportion, these assumptions must be true.

n t ≥ 10

n(1 - t) ≥ 10

Write the proportion of lead to significant as a decimal number first,

42%

= 0.42

Now substitute the sample proportion and the sample size, 479, the assumptions are inserted into the equations to see if they are satisfied.

⇒(479X0.42) 201.18

⇒ (479)(1 − 0.42)

⇒  277.82

Both values are greater than 10, so the assumptions are satisfied, and the margin of error can be calculated.

Determine the margin of error using this formula, where z is the critical value.

[tex]ME = z\sqrt{\dfrac{T(1 - t)}{n} }[/tex]

For a 95% confidence level, z = 1.96.

Substitute the values of z, n, and T into the formula for margin of error and evaluate.

[tex]ME = 1.96\sqrt{\dfrac{0.42(1 - (10.42)}{479} }[/tex]

ME ≈ 0.044

Hence, the margin of error is 0.044.

Clare is deriving the quadratic formula by solving ax^2+bx+c=0 by completing the square.
She arrived at this equation:
(2ax+b)^2=b^2-4ac
Briefly describe what she needs to do to finish solving for I and then show the steps.

Answers

Answer:

Clare starts with:

a*x^2 + b*x + c = 0

And she gets to:

(2*a*x + b)^2 = b^2 - 4*a*c

Now we want to show the final steps to solve the equation (isolating x)

First, we apply the square root to both sides:

[tex]\sqrt{(2*a*x + b)^2} = \sqrt{(b^2 - 4*a*c)}[/tex]

Because the square root has two solutions, (one negative and one positive), we will write:

[tex]2*a*x + b = \pm \sqrt{b^2 - 4*a*c}[/tex]

Now we subtract b in both sides:

[tex](2*a*x + b) - b = \pm \sqrt{b^2 -4*a*c} - b[/tex]

[tex]2*a*x = \pm \sqrt{b^2 -4*a*c} - b[/tex]

Now let's divide by 2*a in both sides:

[tex]2*a*x/(2*a) = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

[tex]x = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

The cost for a pool membership for a family at a community pool is $350 plus $125 per month. A family paid a total of $1,350. How many
months did the family use the pool?

a-11
b-14
c-8
d-12

Answers

Answer:

The family used the pool for 8 months

Step-by-step explanation:

We know that the family paid a total amount of $1,350 dollars. We also know that they had to pay $350 dollars for joining the community pool. Lastly, they paid a monthly fee of $125 dollars. The value "x" represents months.

With that being said, here's our equation.

350 + 125x = 1,350

Subtract 350 from both sides and you should get this:

125x=1,000

Finally, divide 125 from both sides to get the x value.

x=8

Answers

Answer:

a = 7

b = 3 1/2

Step-by-step explanation:

if you add the equations together then the 'b' will zero out

6a = 42

a = 7

substitute 7 for 'a' to solve for 'b'

3(7) - 2b = 14

21 - 2b = 14

-2b = -7

b = 7/2 or 3 1/2
