At a sale, Ricardo bought 24 reams of paper and 4 inkjet cartridges for $320. Britney bought 2 reams of paper and 1 inkjet cartridge for $50. The rams of paper were all the same price and the inkjet cartridges were all the same price. Write a system of equations to represent this situation. Determine the best method to solve the system of equations. Then solve the system.

Options :

A.) A student who missed 2 words on the test wrote each word 4 times.

B.) A student who wrote each word once missed 6 words on the test.

C.) A student who did not write the words missed 8 words on the test.

D.) A student who missed 4 words on the test wrote each word 3 times.

Answer:

A student who did not write the words missed 8 words on the test.

Step-by-step explanation:

From the scatter plot, we could identify all the other points except that of option C.

For option A : (4, 2) is a marked point on the graph

For option B : (1, 6) is also a marked point on the graph

For option C : (0, 8) is not a marked point on the graph and hence, does not match Tiffany's scatter plot.

Answer:

m<M= 85° m<N= 85°

Step-by-step explanation:

To find the value of x we should...

Sum of all angles = 360°

95+95+10x-5+8x+13 = 360

198+18x = 360

18x = 360-198

18x = 162

x = 162÷18

x = 9

m<M = (10×9)-5 = 90-5 = 85°

m<N = (8×9)+13 = 72+13 = 85°

Answer:

x = 9

∠M = 85°

∠N = 85°

Step-by-step explanation:

360 = 95 + 95 + (10x-5) + (8x + 13)

reduce:

18x = 162

x = 9

∠M = 85°

∠N = 85°

Answer:

A. 2

Step-by-step explanation:

From the diagram, it is indicated;

AD = DB = 3t,

AC = 7t + 6

CE = EB = 4t

Perimeter = 48 units

Perimeter = AD + DB + AC + CE + EB

Plug in the values

48 = 3t + 3t + 7t + 6 + 4t + 4t

Add like terms

48 = 21x + 6

48 - 6 = 21x + 6 - 6

42 = 21x

42/21 = 21x/21

2 = x

x = 2

Answer:   [tex]p \ \wedge \ q[/tex]

The upside down V symbol is known as a wedge. It represents a conjunction which is informally the "and". In other words, [tex]p \ \wedge \ q = \text{p and q}[/tex]

Note how we can replace p with "the taxes are high" and replace q with "the job pays well" to arrive at the overall compound statement "The taxes are high and the job pays well".

Some logic textbooks will use an ampersand symbol & to be used in place of a wedge. It will depend on the notation that they, or your teacher, has set up.

Answer:

x = 1

Step-by-step explanation:

Answer:

[tex]x = 1[/tex]

step By Step Explanations:

1) Remove parentheses.

[tex]13 - 2x - 2 = 2(x + 2) + 3x[/tex]

2) Simplify 13 - 2x - 2 to -2x + 11.

[tex] - 2x + 11 = 2(x + 2) + 3x[/tex]

3) Expand.

[tex] - 2x + 11 = 2x + 4 + 3x[/tex]

4) Simplify 2x + 4 + 3x to 5x + 4.

[tex] - 2x + 11 = 5x + 4[/tex]

5) Add 2x to both sides.

[tex]11 = 5x + 4 + 2x[/tex]

6) Simplify 5x + 4 + 2x to 7x + 4.

[tex]11 = 7x + 4[/tex]

7) Subtract 4 from both sides.

[tex]11 - 4 = 7x[/tex]

8) Simplify 11 - 4 to 7.

[tex]7 = 7x[/tex]

9) Divide both sides by 7.

[tex]1 = x[/tex]

10) Switch sides.

[tex]x = 1[/tex]

Therefor, the answer is x = 1.

Answer:

8 cubic feet

Step-by-step explanation:

First find the volume of the sand box

2 x 2 x 3 = 12

then multiply the total volume by 2/3

12 x 2/3 = 8

That leaves you with the total cubic feet of sand he would need.

Answer:

12 and 78

Step-by-step explanation:

The sum of complementary angles is 90 degrees

X+(x-66) = 90

2x = 156    x =  78

78-66 = 12

The correct statement which does not describe the data set is,

⇒  It has a range of 19.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

A data set has these values:

⇒ 10, 12, 12, 14, 14, 14, 14, 16, 16, 18

Hence, We get;

Range = 18 - 10 = 9

Median = 10/2 + 1 term

            = 5 + 1 term

            = 6th term

           = 14

Thus, The correct statement which does not describe the data set is,

⇒  It has a range of 19.

Answer:

A. 390

Step-by-step explanation:

An exponential function can be written in the form [tex]f(n)=a\times b^n[/tex], where [tex]a[/tex] is your starting population, [tex]b[/tex] is the factor by which the population increases, and [tex]n[/tex] is the number of terms. In this case, [tex]a=740[/tex], [tex]b=0.88[/tex] because the population decreases by 12 percent (1-0.12=0.88), and [tex]n=5[/tex].

Thus, [tex]f(5)=740 \times 0.88^5[/tex], which is roughly equal to 390.

Step-by-step explanation:

Answer:

n would have to be at least 16577

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

Out of n randomly selected students he finds that that exactly half attend their home basketball games.

This means that [tex]\pi = 0.5[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

About how large would n have to be to get a margin of error less than 0.01 for p

A sample size of n is needed. n is found when M = 0.01. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.01 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.01\sqrt{n} = 2.575*0.5[/tex]

[tex]\sqrt{n} = \frac{2.575*0.5}{0.01}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.01})^2[/tex]

[tex]n = 16576.6[/tex]

Rounding up

n would have to be at least 16577

When the error margin is smaller than 0.01, the value of n will be 16576.6.

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.

Given that;

Confidence interval = 99 %

Randomly selected students,n

margin of error,M0.01

The margin of error for the given information is;

[tex]\rm M = z \frac{\sigma(1-\sigma)}{n} \\\\\ 0.01 = 2.575 \frac{0.5(0.5)}{n} \\\\ 0.01 \sqrt n = 2.575 \times 0.5 \\\\ \sqrt n = \frac{2.575 \times 0.5}{0.01} \\\\ n = 16576.6[/tex]

Hence, the value of n for which the margin of error is less than 0.01 will be 16576.6.
