Answer:

The answer is below

Step-by-step explanation:

1)

mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65

Given that the confidence level (c) = 90% = 0.9

α = 1 - c = 0.1

α/2 = 0.05

The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65

The margin of error (E) is given as:

[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.65*\frac{2.3}{\sqrt{65} } =0.47[/tex]

The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)

2)

mean (μ) = 23, SD(σ) = 12, sample size (n) = 45

Given that the confidence level (c) = 88% = 0.88

α = 1 - c = 0.12

α/2 = 0.06

The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56

The margin of error (E) is given as:

[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.56*\frac{12}{\sqrt{45} } =2.8[/tex]

The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)

Answer:

Step-by-step explanation:

3/4*8=6

The requried number of Ruth filled with soda is 6 cups.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,

To find the number of cups Ruth filled with soda, we need to divide the amount of soda she poured into cups by the amount of soda in each cup.

Ruth poured 1/8 liter of soda into cups. To convert this to cups, we need to know that 1 liter is equal to 4 cups. So, 1/8 liter is equal to:

(1/8) x 4 cups = 0.5 cups

Ruth has 3/4 liters of soda in her refrigerator, which is equal to:

(3/4) x 4 cups = 3 cups

So, the number of cups Ruth filled with soda is:

= 3 / 0.5
= 6 cups

Thus, the requried number of Ruth filled with soda is 6 cups.

Answer:

x = 180

∠DBC = 23

∠ABC = 157

Step-by-step explanation:

A straight line is always 180 degrees

A to D line = 180

6x + 19 + x = 180

7x + 19 = 180

      -19     -19

7x = 161

/ 7     / 7

161 /7 = 23

x = 23

Then plug it in

6x + 19

6 ( 23 ) + 19 = 157

x

x = 23

Answer:

Step-by-step explanation:

1) 5/12

To make the denominator to 36, 12 should be multiplied by 3. As we are multiplying the denominator by 3, numerator also should multiplied by 3

[tex]\frac{5}{12}=\frac{5*3}{12*3}=\frac{15}{36}[/tex]

2) 1/6

[tex]\frac{1}{6}=\frac{1*6}{6*6}=\frac{6}{36}\\[/tex]

3) 7/9

[tex]\frac{7}{9}=\frac{7*4}{9*4}=\frac{28}{36}[/tex]

Answer:

(2, - 4 )

Step-by-step explanation:

Given the 2 equations

10x + 7y = - 8 → (1)

7x + 7y = - 14 → (2)

Subtract (2) from (1) term by term to eliminate y

(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (1)

10(2) + 7y = - 8

20 + 7y = - 8 ( subtract 20 from both sides )

7y = - 28 ( divide both sides by 7 )

y = - 4

solution to the system of equations is (2, - 4 )

Answer:

2 50ml bottles

Step-by-step explanation:

Reading through the question, we have:

For 80mL

[tex]C_1 = \pounds 55[/tex]

For 2 50mL bottles.

The cost is calculated by the original cost + half the original cost.

i.e.

[tex]C_2 = \pounds 45 + \frac{1}{2} * \pounds 45[/tex]

[tex]C_2 = \pounds 45 + \pounds 22.5[/tex]

[tex]C_2 = \pounds 67.5[/tex]

Next, is to calculate the unit price of each.

For 80mL

[tex]C_1 = \pounds 55[/tex]

[tex]Unit\ price = 55/80[/tex]

[tex]Unit\ price = 0.6875[/tex]

For 2 50mL bottles.

[tex]C_2 = \pounds 67.5[/tex]

[tex]Unit\ price - 67.5/(2 * 50)[/tex]

[tex]Unit\ price = 67.5/100[/tex]

[tex]Unit\ price = 0.675[/tex]

By comparison, the 2 50mL is the best buy because it has smaller unit price

Answer:

16^2 = 8^2 + x^2

x^2 = 16^2  -8^2

x^2 = 256 -64

x^2 = 192

x = sq root (192) =  13.8564064606

Step-by-step explanation:

The equation is given as;

−4(x−3)=20

Gwendolyn's flaw is in the following lines;

−4x + 12 = 20

−4x = 32

When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12

The correct solution is given as follows;

Step 1: Expand the brackets

This results to;

- 4x - (-4 * 3) = 20

-4x + 12 = 20

Step 2: Collect like terms

This results to;

- 4x = 20 - 12

- 4x = 8

Step 3: Solve for x

x = 8 / (-4)

x = -2

From the upper right corner, there are 8 people who do not like reading.

On the lower right corner of the table, there is 1 one person who does not like reading and playing video games

On the lower left corner, there are two people who do not like playing video games.

The total number of people who do not like reading = 8 + 1 = 9

The total number of people who do not like playing video games = 2 + 1 = 3

= 9 : 3

Complete Question:

Complete each equation, so the statement about its solution is true.

No solutions:

6-3+4x+1= __x + __

One solution:

6-3+4x+1= __x + __

Infinitely many solutions:

6-3+4x+1 = __x + __

Answer:

[tex]4 + 4x = 4x + 3[/tex] --- No solution

[tex]4 + 4x = 3x + 2[/tex] --- One solution

[tex]4 + 4x = 4 + 4x[/tex] --- Infinitely Many solution

Step-by-step explanation:

Solving (a): No solutions

6-3+4x+1= __x + __

Collect like terms

6-3+1+4x= __x + __

4+4x= __x + __

To get no solution, the coefficient of x on both sides must be the same. However, the constant must be different.

So, we can equate the expression to:

[tex]4 + 4x = 4x + 3[/tex]

Solving (b): One solution

6-3+4x+1= __x + __

This gives (same as (a))

4+4x= __x + __

To get one solution, the coefficient of x on both sides must be different. The constant can have any value.

So, we can equate the expression to:

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

Solving (c): Infinitely many solutions

6-3+4x+1= __x + __

This gives (same as (a))

4+4x= __x + __

To get infinitely many solutions, both sides of the equation must be equal.

So:

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