vol=1/3*pi*r^2*h
curved surface area =pi*r*l

Answer:

3825 pages

Step-by-step explanation:

Add the pages together:

1349+1281+1195 = 3825 pages

Danny read a total of 3,825 pages over winter break, which is well above 1,050 pages, indicating that it was very likely he had to read more than 1,050 pages.

Danny read three books over winter break. To determine the total number of pages Danny read, we need to add up the pages from each book. Here is the step-by-step explanation:

First book: 1,349 pages

Second book: 1,281 pages

Third book: 1,195 pages

Add these numbers together:

1,349 + 1,281 + 1,195 = 3,825 pages in total

Therefore, Danny read a total of 3,825 pages over the break. Clearly, this number is much greater than 1,050 pages, so without doing any calculations, we could confidently say that it's highly likely that Danny had to read more than 1,050 pages based on the individual page counts of each book provided.

Answer:377.46 N

Step-by-step explanation:

Given

Vector 1 has a magnitude of [tex]360\ N[/tex] and makes an angle of [tex]30^{\circ}[/tex]

vector 2 has a magnitude of [tex]240\ N[/tex] and makes an angle of [tex]135^{\circ}[/tex]

Net Horizontal force

[tex]\sum F_h=360\cos 30+240\cos 135[/tex]

[tex]\sum F_h=311.769-169.70[/tex]

[tex]\sum F_h=142.069\ N\quad \ldots(i)[/tex]

Mike and his friends hiked 16 miles on Sunday. They have hiked a total of 39 miles over Saturday and Sunday, which is 11 miles short of their 50-mile goal.

Mike and his friends hiked a total of 23 miles on Saturday and hiked 7 miles less on Sunday. To find out how many miles they hiked on Sunday, we subtract 7 miles from the 23 miles they hiked on Saturday.

So, Sunday's hiking distance = Saturday's hiking distance - 7 miles
Sunday's hiking distance = 23 miles - 7 miles
Sunday's hiking distance = 16 miles.

Now, to check if they met their hiking goal of 50 miles during their trip, we add the distances hiked on both days:
Total hiking distance = Saturday's hiking distance + Sunday's hiking distance
Total hiking distance = 23 miles + 16 miles
Total hiking distance = 39 miles.

They have hiked 39 miles so far, which is short of their 50-mile goal.

Answer:

Y intercept is -10

Step-by-step explanation:

Answer:

slope = -4

y-intercept = -10

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 4x from both sides:

4x (-4x) + y = -10 (-4x)

y = -4x - 10

Note the slope intercept form: y = mx + b

y = y

m = slope = -4

x = x

b = y-intercept = -10

slope = -4

y-intercept = -10

The mean of the sampling distribution of p  is 0.70  and the standard deviation is 0.029 .

To find the mean and standard deviation of the sampling distribution of p , we can use the properties of sampling distributions.

Given:

Sample size, n = 250

Proportion of subscribed households who watch sports,  p = 0.70 (from the population)

Sample proportion of households who watch sports, [tex]\( \hat{p} = 0.75 \)[/tex](from the sample)

The mean of the sampling distribution of p  is equal to the population proportion, which is  p = 0.70 .

The standard deviation of the sampling distribution of p  can be calculated using the formula:

[tex]\[ \sigma_{\hat{p}} = \sqrt{\frac{p(1-p)}{n}} \][/tex]

Substituting the given values:

[tex]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.70(1-0.70)}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.70 \times 0.30}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{\frac{0.21}{250}} \]\[ \sigma_{\hat{p}} = \sqrt{0.00084} \]\[ \sigma_{\hat{p}} = 0.029 \][/tex]

So, the mean of the sampling distribution of p  is 0.70  and the standard deviation is 0.029 .

Question

The cable company takes an SRS of 250 of the approximately 15,000 households who subscribe to them. They found that 75, percent of the sampled households watch sports on television at least once a month. The company is considering taking more samples like this. Suppose that it is actually 70, percent of their total subscribed households who watch those sports.

Let p represent the proportion of a sample of 250 households that watch sports on television at least once a month.

What are the mean and standard deviation of the sampling distribution of p?

Step-by-step explanation:

The professional soccer player buys 16 acres of land.

He wants to use [tex]\frac{2}{8}[/tex] of the land to put his own soccer field and facility on.

All we have to do is find [tex]\frac{2}{8}[/tex] of 16 acres.

[tex]\frac{2}{8}[/tex] of 16 acres:

[tex]\frac{2}{8}[/tex] * 16 = 4 acres

He will need 4 acres out of the 16 acres for his soccer field and facility.

Given Information:

Distance = d = 12 miles

Time = t = 15 minutes

Required Information:

Speed of the bus = r = ?

Answer:

Speed of the bus = r = 48 mph

Step-by-step explanation:

We are given that a bus has traveled a distance of 12 miles in a time period of 15 minutes.

We are required to find the rate or speed at which the bus is traveling.

The relation is given by

[tex]rate = \frac{distance}{time}\\\\r = \frac{d}{t}[/tex]

Where r is the rate or speed, d is the distance and t is the time.

First let us convert time from minutes to hours

as we know 1 hour has 60 minutes,

15/60 = 0.25 hour

Now we will get the speed of the bus in miles per hour

[tex]r = \frac{d}{t}\\\\r = \frac{12}{0.25}\\\\r = 48 \: mph[/tex]

Therefore, the speed of the bus is 48 miles per hour.

To estimate the probability of a meerkat living between 12.3 and 14.2 years, we can use the empirical rule (68-95-99.7%).

The probability of a meerkat living between 12.3 and 14.2 years can be estimated using the empirical rule (68-95-99.7%).

Next, use a standard normal distribution table or a calculator to find the probabilities associated with these z-scores.

Finally, subtract the probability of the lower value from the probability of the higher value to find the probability of a meerkat living between 12.3 and 14.2 years.

Answer:

Step-by-step explanation:

The initial value is always the value that corresponds to the independent variable being 0. Here, that's the first entry in the table. The initial Height is 0, when Time is 0.

__

The rate of change can be figured by looking at the change in Height for a change of 1 in Time. Here, the height changes by 200 m for every 1 min change in time. The rate of change is 200 m/min.

__

The equation can be written in slope intercept form using the rate of change and initial value:

  (dependent variable) = (rate of change)×(independent variable) + (initial value)

  H = 200T + 0

  H = 200T . . . . . . . . height in meters for time in minutes

Answer:

1,290,000

Step-by-step explanation:

Answer:

1,290,000

Step-by-step explanation:

If we are rounding to the nearest thousand, then we are finding the number in the hundredth's and rounding it.

From 1-9 If it's less than 5, round down. If it's 5 or more, round up.

At this case, it is 8 in the hundredths and nine in the thousandths. Since 8 is 5 or greater, you round it up to 1000, but the thousandth's place has a nine, which nine plus 1 is 10.

Therefore, 1,289,845 rounded up is 1,290,000.

Answer"

Jen's speed is 0.04 miles per minute.

To find Jen's speed, we need to divide the distance she traveled by the time it took her to get there. In this case, Jen traveled 1/5 of a mile and it took her 5 minutes. To find her speed in miles per minute, we divide the distance (1/5 mile) by the time (5 minutes):

Speed = Distance ÷ Time

Speed = 1/5 mile ÷ 5 minutes

To simplify the calculation, we can convert 1/5 mile to a decimal by dividing 1 by 5:

1/5 = 0.2

Now we can divide 0.2 by 5 to find Jen's speed:

0.2 ÷ 5 = 0.04

Therefore, Jen's speed is 0.04 miles per minute.

Answer: 69

Step-by-step explanation:

If I do this with 4 and 5 - I get 29.

This can be explained as this:

4 + (5^2) = 4 + 25 = 29

If I do the same thing with 4 and 6 - I get 40. This can be explained as:

4 + (6^2) = 4 + 36 = 40

Thesame thing again to 8 and 9 gives me 89. This can be explained as:

8 + (9^2) = 8 + 81 = 89

What do I get if I do the same thing to 5 and 8. This will be:

5 + (8^2) = 5 + 64 = 69

Answer:

angle FBE

Step-by-step explanation:

By using the formula, the shortest angle is facing the shortest side

so the shortest angle is angle FBE

In triangle ADEF, angle E is the smallest angle.

In triangle ADEF, we are given that DE = 25 cm, EF = 17 cm, and DF = 20 cm. To determine which angle is the smallest, we need to compare the lengths of the sides opposite each angle. The smallest angle will have the smallest side opposite it. Let's compare the lengths:

Side DE is opposite angle D.

Side EF is opposite angle E.

Side DF is opposite angle F.

Since side EF (length 17 cm) is the smallest, angle E is the smallest angle in triangle ADEF.
