Kwasi bought `15` postage stamps for `\$8.25`. All stamps cost the same amount. How many stamps can Kwasi purchase with $22

The amplitude is 6 and vertical translation is 2. Therefore Option C is correct

For the transformation of y=f(x) to f(x)+k, for k>0, f(x) is moved k upwards and for transformation of f(x) to f(ax) it depends upon the value of a If |a|>1 then f(ax) is f(x) squashed horizontally by a factor of a and If 0<|a|<1 then f(x) is stretched horizontally by a factor of a.

So by the graph it is clearly visible that amplitude of the graph is 6 as the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough is 6 and the vertical translation is 2 as distance moved by the graph upwards is 2.

Thus the amplitude is 6 and vertical translation is 2.

The z-score associated with a 95% confidence level is approximately 1.96.

The z-score associated with a 95% confidence level is the value of the standard normal distribution that corresponds to an area of 0.95 to the left of the z-score.

Using a standard normal distribution table or calculator, we can find that the z-score associated with a 95% confidence level is approximately 1.96.

Therefore, if we want to calculate the z-score for a 95% confidence level, we can use the formula

z = invNorm(1 - α/2)

where α is the significance level (α = 0.05 for a 95% confidence level), and inv Norm is the inverse normal cumulative distribution function. Using this formula, we can calculate the z-score as:

z = inv Norm(1 - 0.05/2)

= inv Norm(0.975) ≈ 1.96

Therefore, the z-score is 1.96

well, we know she paid a total after tax of $68.37, we also know that each game had a tax of $1.29, so 3 games that'll be 3 * 1.29 = 3.87.

so if we take out the tax from 68.37, that'll be 68.37 - 3.87 = 65 bucks.

we know each game cost the same amount so 65 ÷ 3 ≈ 21.67 before tax.

Tiana bought 3 video games at a cost of $22.36 each, before tax. The total amount paid after tax was $68.37.

Given that,

Tiana bought 3 video games.

The cost of each video game was the same.

The tax on each video game was $1.29.

Tiana paid a total of $68.37 after tax.

To find the price of each video game before tax,

Start by subtracting the total tax from the total amount paid.

Tiana paid a total of $68.37 after tax and the tax on each video game was $1.29.

So, subtract the tax from the total amount to get the price before tax.

$68.37 - $1.29 = $67.08.

Since Tiana bought 3 video games,

Divide the total price before tax by 3 to find the price of each video game.

$67.08 ÷ 3 = $22.36.

Hence, the price of each video game before tax was $22.36.

Answer:

x < -5

Step-by-step explanation:

-0.6x > 3

=> Dividing 0.6 on both sides

=> -x > 3/0.6

=> -x > 5

=> x < -5     [When we multiply -1 on both sides the sign changes]

The solution to the inequality -0.6x > 3 is x < -5.

To solve for x in the inequality -0.6x > 3, we need to isolate x on one side of the inequality.

First, to divide both sides of the inequality by -0.6 to remove the coefficient in front of x.

Remember that when dividing or multiplying both sides of an inequality by a negative number, we need to reverse the inequality sign.

So, dividing both sides by -0.6 gives

x < 3 / -0.6

Simplifying the right side of the inequality, we have:

x < -5

Therefore, the solution to the inequality -0.6x > 3 is x < -5.

(a) The visitors are from a simple random sample, so independence is satisfied. The success/failure condition is also satisfied, with both 64 and 752 − 64 = 688 above 10. Therefore, we can use a normal distribution to model phat and construct a confidence interval.

(b) The sample proportion is phat = 0.085, SE = 0.010

(c) For a 90% confidence interval, use z⋆ = 1.65. The confidence interval is 0.085 ± 1.65 × 0.010 → (0.0685, 0.1015). We are 90% confident that 6.85% to 10.15% of first-time site visitors will register using the new design.

Normal distribution is a statistical concept that describes the probability distribution of a random variable that is continuous and symmetric around its mean. It is also known as Gaussian distribution or bell curve because of its characteristic bell-shaped curve. The normal distribution is important in statistical analysis because it occurs naturally in many real-world situations, such as the distribution of heights, weights, and test scores. It is also used in hypothesis testing and in the construction of confidence intervals.

The normal distribution is characterized by two parameters: the mean, which is the central tendency of the distribution, and the standard deviation, which measures the spread or dispersion of the distribution. The standard deviation determines the width of the bell curve, with a larger standard deviation indicating a wider curve.

Step-by-step explanation:

1) add 8 on both sides, then divide by 4 on both sides. (4x)

2) multiply by 12 on both sides, then add 5 on both sides.

The system of equations [x - 3y = -1 and -6x + 19y = 6] can be solved, resulting in x = -1 and y = 0.

To solve the system of equations [x - 3y = -1 and -6x + 19y = 6], we can use the method of substitution or elimination.

Let's solve it using the method of elimination.

First, we can multiply the first equation by 6 and the second equation by -1 to eliminate the x terms.

This gives us [6x - 18y = -6 and 6x - 19y = -6].

Now, subtracting the first equation from the second eliminates the x terms, leaving us with -y = 0. Solving for y, we find y = 0.

Substituting this value back into the first equation, we get x - 3(0) = -1, which simplifies to x = -1.

Therefore, the solution to the system of equations is x = -1 and y = 0.

We can use Coulomb's law to calculate the magnitude of the electric field at a distance r away from a point charge Q:

E = k * Q / r^2

where k is Coulomb's constant, Q is the charge of the point charge, and r is the distance from the point charge.

In this problem, we have a point charge Q of -10 nC located at (1.2 cm, 0 cm), and we want to find the x-component of the electric field at a distance r = 5.3 cm away at position (-4.1 cm, 0 cm).

To find the x-component of the electric field, we need to use the cosine of the angle between the electric field vector and the x-axis, which is cos(180°) = -1.

So, the x-component of the electric field at position (-4.1 cm, 0 cm) is:

E_x = - E * cos(180°) = - (k * Q / r^2) * (-1)

where k = 9 x 10^9 N*m^2/C^2 is Coulomb's constant.

Substituting the given values, we get:

E_x = - (9 x 10^9 N*m^2/C^2) * (-10 x 10^-9 C) / (0.053 m)^2

E_x ≈ -30,566.04 N/C

Rounding this to two significant figures and including the appropriate units, we get:

The x-component of the electric field is about -3.1 x 10^4 N/C (to the left).

Answer:

-15°

Step-by-step explanation:

We know that at 7 pm it started at -6°, and that every 2 hours until 2 am, it dropped by 2 degrees.

From that we can form this expression:

-6-2x, with x being the number of hours it dropped.

From 7 pm to 2 am is 7 hours, therefore -6-2(7) = -20°

From 2 am until 7 am, it began raising 1 degree per hour.

We can write that as:

-20 + x, with x being the number of hours it went up.

From 2 am to 7 am is 5 hours:

-20 + 5 = -15°

Therefore, the temperature at 7 am is -15°.

Step-by-step explanation:

Answer:

- 9.6 oz butter

- 8 oz sugar

- 12 oz flour

- 4 eggs

Step-by-step explanation:

We know that for 20 cupcakes, we need the following amount for each ingredient:

- 12 oz butter

- 10 oz sugar

- 15 oz flour

- 5 eggs

We now only want 16 cupcakes. To find how much of each ingredient we need, let's write a proportion for each. Say b is the amount of butter we need, s is the amount of sugar, f is flour, and e is eggs:

16 cupcakes / 20 cupcakes = b oz butter / 12 oz butter

16 cupcakes / 20 cupcakes = s oz sugar / 10 oz sugar

16 cupcakes / 20 cupcakes = f oz flour / 15 oz flour

16 cupcakes / 20 cupcakes = e eggs / 5 eggs

These turn out to become:

20b = 16 * 12  ⇒  b = 9.6 oz butter

20s = 16 * 10  ⇒  s = 8 oz sugar

20f = 16 * 15  ⇒  f = 12 oz flour

20e = 16 * 5  ⇒  e = 4 eggs

Thus, our answers are:

- 9.6 oz butter

- 8 oz sugar

- 12 oz flour
