Answer:

32.43

Step-by-step explanation:

To get the standard divisor

We sum up the tickets sold

Applejack's = 66 tickets

Broncos = 769 tickets

Colts = 652 tickets

Deers = 556 tickets

The total prize amount = $63

Total tickets = 66 + 769 + 652 + 556 = 2043

Standard divisor = 2043/63

= 32.43

The standard divisor to two decimal places is 32.43

Answer:

11.383

Step-by-step explanation:

the third place is the thousandths.

By rounding 11.3826 to the nearest thousand, we get 11.383.

The number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Example: 0.2358 rounded to the nearest thousand is 0.236.

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

Example: 0.7231 rounded to the nearest thousand is 0.723.

Given number is 11.3826.

Rounding to nearest thousand, we get:

11.3826 ⇒ 11.383.

Answer:708

Step-by-step explanation:

breadth= X

L= x+30

after you cut a square with 6in from the corners, the length becomes x+30-6 =x+24 and breadth becomes x-6.

The eqn for volume of box is Length x Breadth x height

it's given that LxBxH = 1050

here height is 6, because u are folding the edge where it's been cut off and that side becomes the height.

rewrite with the given information we get

(x+24)*(x-6)*6 = 1050

divide both sides with 6

(x+25)*(x-6) = 175

distribute the brackets we get,

x^2 -18x -144 =175

x^2 -18x-319 = 0

solve for x using quadratic formula.

we get x= 29, -11

since length cannot be negative x= 29

B= 29, L=59.

Answer:

0.7517 = 75.17% probability that the mean IQ of the 3 North Catalina students is at least 5 points higher than the mean IQ of the 3 Chapel Mountain students

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Subtraction of normal variables:

When we subtract normal variables, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

North Catalina:

Population has mean 130 and standard deviation 8 points. Sample of 3. This means that:

[tex]\mu_{N} = 130, s_{N} = \frac{8}{\sqrt{3}} = 4.6188[/tex]

Chapel Mountain:

Population has mean 120 and standard deviation 10 points. Sample of 3. This means that:

[tex]\mu_{C} = 120, s_{C} = \frac{10}{\sqrt{3}} = 5.7735[/tex]

What is the probability that the mean IQ of the 3 North Catalina students is at least 5 points higher than the mean IQ of the 3 Chapel Mountain students?

We want that: [tex]N - C > 5[/tex]

Distribution N - C:

The mean is:

[tex]\mu = \mu_N - \mu_C = 130 - 120 = 10[/tex]

The standard deviation is:

[tex]s = \sqrt{s_N^2+s_C^2} = \sqrt{4.6188^2+5.7735^2} = 7.3937[/tex]

This probability is 1 subtracted by the pvalue of Z when X = 5. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{5 - 10}{7.3937}[/tex]

[tex]Z = -0.68[/tex]

[tex]Z = -0.68[/tex] has a pvalue of 0.2483

1 - 0.2483 = 0.7517

0.7517 = 75.17% probability that the mean IQ of the 3 North Catalina students is at least 5 points higher than the mean IQ of the 3 Chapel Mountain students

Step-by-step explanation:

Factors for 28: 1, 2, 4, 7, 14, and 28

Factors for 35: 1, 5, 7, and 35

Answer:

Step-by-step explanation:

The required equation is x+295=285 , where x= starting altitude( in feet).

The starting altitude is -11 feet.

Let x be the starting altitude( in feet) .

Given: The Hiking Club is taking another trip. The hike leader's watch shows that they gained 296 feet in altitude from their starting position.

Then, the altitude is now = x+ 296

Since their altitude is now 285 feet.

So the required equation is x+296=285

Subtract 296 from both sides, we get

x= -11

Answer:

3/2

Step-by-step explanation:

Given

[tex]t_1 = 96[/tex]

[tex]r = \frac{1}{4}[/tex]

Required

Find t4

The nth term of a geometric sequence is calculated as:

[tex]t_n = t_1 * r^{n-1[/tex]

So:

[tex]t_4 = t_1 * r^{4-1[/tex]

[tex]t_4 = t_1 * r^3[/tex]

This gives:

[tex]t_4 = 96 * \frac{1}{4}^3[/tex]

[tex]t_4 = 96 * \frac{1}{64}[/tex]

Express as a single fraction

[tex]t_4 = \frac{96}{64}[/tex]

[tex]t_4 = \frac{3}{2}[/tex]

Hence, the 4th term is 3/2

Answer:

B. x = 1/4y²

Step-by-step explanation:

The equation of a parabola is x = 1/4y². Therefore, option B is the correct answer.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

From the graph,

x-intercept(s): (0,0)

y-intercept(s): (0,0)

Vertex is (0, 0)

Directrix, x=-1

Here, the axis of symmetry is y=0

So, the equation is x = 1/4y²

Therefore, option B is the correct answer.
