Answer:

6 apples will weigh about 1,533 grams

Step-by-step explanation:

Set up an equation:

2

Variable x = weight of 6 apples

2/511 = 6/x

Cross multiply

2 × x = 511 × 6

2x = 3066

Divide both sides by 2

x = 1533

Check your work

2/511 = 6/1533

2 × 1533 = 511 × 6

3066 = 3066

Answer:

$3990

Step-by-step explanation:

First, if the tuition increased by 300 the first year, and 330 the next year, I can infer that the tuition increases by $30 a year. This year, the the tuition will cost 360, because 330 + 30 = 360. So, this year the tuition will be 3990, because 3630 + 360 = 3990.

Answer:

The answer is 46

Step-by-step explanation:

Since there is a diagonal, you can't assume that it is the width because if it was the width, it would say so. Since 17 was the measure of the diagonal, I did pythagorean theorem: 15^2 + x^2 =  17^2 --> 225 + x^2 = 289 --> x^2 = 64 --> x = 8. So now we have figured out the width of the rectangle and it's 8. Now we can add: 8 + 8 + 15 + 15 = 46. That is why the answer is 46.

The perimeter of the rectangle  46 feet.

The correct option is (A).

Perimeter is the distance around the edge of a shape.

Learn how to find the perimeter by adding up the side lengths of various shapes.

Given : length= 15 feet and diagonal= 17 feet

Since there is a diagonal.

So, using Pythagorean theorem:

H² = P²+B²

15²+ x² =  17²

or, 225 + x² = 289

or, x² = 64

x = ± 8 feet.

Thus, width = 8 feet

Perimeter of rectangle= 2*(l+b)

= 2*(15+8)

= 2*23

=46 feet

Answer:

Step-by-step explanation:

Exponential function representing final amount with compound interest compounded continuously,

[tex]A=Pe^{rt}[/tex]

Here, A = Final amount

P = principal amount

r = Rate of interest

t = Duration of investment

For P = $9600

r = 6%

A = 2 × 9600 = $19200

By substituting these values in the formula,

[tex]19200=9600(e)^{0.06\times t}[/tex]

[tex]2=e^{0.06t}[/tex]

[tex]ln(2)=ln(e^{0.06t})[/tex]

ln(2) = 0.06t

t = [tex]\frac{0.693147}{0.06}[/tex]

t = 11.55245

t ≈ 11.5525 years

Any amount will get doubled (with the same rate of interest and duration of investment) in the same time.

Therefore, $960000 will get doubled in 11.5525 years.

Answer:

The correct answer is G(1, 4).so go through it.

Given:

A prism has a base area of [tex]20\pi [/tex] square units and a volume of [tex]120\pi[/tex] cubic units.

To find:

The volume of the cylinder if the cylinder has the same base area and height.

Solution:

Volume of a prism is:

[tex]V=Bh[/tex]

Where, B is the base area and h is the height of the prism.

The volume of cylinder is:

[tex]V=\pi r^2h[/tex]

[tex]V=Bh[/tex]

Where, r is the radius, h is the height of the cylinder and [tex]B=\pi r^2[/tex] is the base area.

Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.

Hence the volume of the cylinder is [tex]120\pi[/tex] cubic units.

Answer: 67.7ft²

Step-by-step explanation:

Note that a heptagon has 7 sides.

The area of a heptagon is given as:

= 1/2 × nsr

where,

n = number of sides = 7

s = length of side = 4.3ft

r = apothem= 4.5ft

Area of the heptagon = ½nsr

= ½ × 7 × 4.3 × 4.5

= 135.45/2

= 67.7ft²

Therefore, the area of the heptagon is 67.7ft²

Step-by-step explanation:

Answer:

The 90% confidence interval for the difference in the mean common final exam scores between students in the two types of sections is about (-5.3, 0.3).

Step-by-step explanation:

Before building the confidence interval, we need to understand the central limit theorem and subtraction between normal variables.

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.

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

35 students from large sections. The mean and sample standard deviation of grades on the common final exam for the students from large sections were 72.8 and 7.4;

This means that:

[tex]\mu_L = 72.8, s_L = \frac{7.4}{\sqrt{35}} = 1.25[/tex]

35 students from small sections. For the students from small sections, the mean and standard deviation were 75.3 and 6.8.

This means that:

[tex]\mu_S = 75.3, s_S = \frac{6.8}{\sqrt{35}} = 1.15[/tex]

Distribution of the difference in the mean common final exam scores between students in the two types of sections:

Has mean and standard error given by:

[tex]\mu = \mu_L - \mu_S = 72.8 - 75.3 = -2.5[/tex]

[tex]s = \sqrt{s_L^2+s_S^2} = \sqrt{1.25^2 + 1.15^2} = 1.7[/tex]

Confidence interval:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.

Now, find the margin of error M as such

[tex]M = zs = 1.645*1.7 = 2.8[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is -2.5 - 2.8 = -5.3

The upper end of the interval is the sample mean added to M. So it is -2.5 + 2.8 = 0.3

The 90% confidence interval for the difference in the mean common final exam scores between students in the two types of sections is about (-5.3, 0.3).
