Answer:

It takes 4.75 hours(4 hours and 45 minutes) to travel 247 miles.

Step-by-step explanation:

This question is solved by rates, using a rule of three.

52 miles in one hour. How many hours for 247 miles?

1 hour - 52 miles

x hours - 247 miles

Applying cross multiplication:

[tex]52x = 247[/tex]

[tex]x = \frac{247}{52}[/tex]

[tex]x = 4.75[/tex]

It takes 4.75 hours = 4 hours and 3/4*60 = 45 minutes to travel 247 miles.

This is Right answer....

Answer:

0.0713 = 7.13% probability that the result is positive.

Step-by-step explanation:

Probability of a positive test:

91% of 1/650(has the disease).

7% of 1 - 1/650 = 649/650(does not have the disease). So

[tex]p = 0.91\frac{1}{650} + 0.07\frac{649}{650} = \frac{0.91 + 0.07*649}{650} = 0.0713[/tex]

0.0713 = 7.13% probability that the result is positive.

Step-by-step explanation:

Answer:

An apothem is a line drawn from the centerpoint of the polygon to one side of the polygon. There is a formula for area in terms of apothem:

A = (1/2)*(Perimeter)*(Apothem)

The perimeter of the regular polygon  is just the length of one side multiplied with the number of sides. Since a polygon with   9 sides,

P = 9(15) = 135in

A = 1/2 ×135 × 12

A = 810 square inches ans

Answer:

Area = x² + 8x + 7

Step-by-step explanation:

Area of a rectangle formula = L * W

Length (L) of the given figure = (x + 7)

Width (W) of the given figure = (x + 1)

Area = L * W

Area = (x + 7) * (x + 1)

=> x * x = x²

=> x * 1 = 1x or x

=> 7 * x = 7x

=> 7 * 1 = 7

Combining it all together;

Area = x² + 1x + 7x + 7

Combine the like terms:

Area = x² + 8x + 7

Hope this helps!

The area of the entire rectangle in the polynomial form will be x² + 8x + 7.

Let W be the rectangle's width and L its length. The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be given as,

Area of the rectangle = L × W square units

The dimensions of the big rectangle are x + 1 high and x + 7 long. Then the area of the rectangle is calculated as,

A = (x + 7)(x + 1)

Simplify the equation, then we have

A = (x + 7)(x + 1)

A = x² + 7x + x + 7

A = x² + 8x + 7

More about the area of the rectangle link is given below.

Answer:

Problematic is that - only one factor should be analysed at a time. However she has considered both.

Step-by-step explanation:

Groups for any experimental study should be selected on the basis of one variable, other factor(s) remaining constant.

In this case, here are two variables - lights on or off, music playing or not playing - effecting relax level during exams.

She selects 10 students for exam with lights off , 10 for exam without music. This is problematic, as at once only lights or only music factor should be considered.

If one group is with light on , other should be with light off. If one group is with music, other should be without music. This mix up of one light off aspect & one music without music is inapt.

Answer:

[tex]p\ =\ 92[/tex]

Step-by-step explanation:

Given

[tex]p\ \alpha\ \frac{1}{q^2}[/tex]

[tex]p =23; q=4[/tex]

Required

Find p, when [tex]q = 2[/tex]

We have:

[tex]p\ \alpha\ \frac{1}{q^2}[/tex]

Express as equation

[tex]p\ =\ \frac{k}{q^2}[/tex]

Make k the subject

[tex]k =pq^2[/tex]

When: [tex]p =23; q=4[/tex]

[tex]k =23 * 4^2[/tex]

[tex]k =368[/tex]

When [tex]q = 2[/tex], we have:

[tex]p\ =\ \frac{k}{q^2}[/tex]

[tex]p\ =\ \frac{368}{2^2}[/tex]

[tex]p\ =\ \frac{368}{4}[/tex]

[tex]p\ =\ 92[/tex]

Answer:

Null Hypothesis: H0: Defective defense missiles not more than 6%

Alternate hypothesis: Ha: Defective defense missiles are greater than 6%

Step-by-step explanation:

The null hypothesis is the problem statement and the alternate hypothesis is a contradiction of null hypothesis

Hence,

Null Hypothesis: H0: Defective defense missiles not more than 6%

Alternate hypothesis: Ha: Defective defense missiles are greater than 6%

Answer:

0.3128

Step-by-step explanation:

H0 : p ≤ 0.28

H0 : μ > 0.28

The test statistic :

(phat - p) ÷ √(pq / n)

q = 1 -p = 1 - 0.28 = 0.72

phat = 0.30

(0.30 -0.28) ÷ √((0.28*0.72) / 120)

0.02 ÷ 0.0409878

Test statistic = 0.48795

Using the Pvalue from test statistic calculator :

Pvalue(0.05, right tailed) = 0.3128

Answer:

length = 5

width = 9

Step-by-step explanation:

V = lwh

let 'x' = length

let '4+x' = width

9 = height

405 = 9x(4+x)

405 = 36x + 9x²

this is a quadratic equation:  9x² + 36x - 405 = 0

factor out a 9 to get:

9(x² + 4x - 45) = 0

9(x-5)(x+9) = 0

one root is 5 and the other is -9

since distance cannot be negative we use 5 as the length and 9 is the width

Answer:

The GMAT score corresponding to the 16th percentile is 473.

Step-by-step explanation:

Empirical Rule.

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

68% of the measures within 1 standard deviation of the mean.

This means that they are between the 50 - (68/2) = 50 - 34 = 16th percentile(one standard deviation below the mean) and the 50 + (68/2) = 50 + 34 = 84th percentile(one standard deviation above the mean).

In this question:

Mean of 549, standard deviation of 76.

16th percentile:

One standard deviation below the mean, so 549 - 76 = 473.

The GMAT score corresponding to the 16th percentile is 473.
