A grain silo has a cylinder shape it’s radius is 7ft and it’s height is 31ft what is the volume of the silo

Answer:

the answer is d

Step-by-step explanation:

before the increase the range is three with the lowest number being four and the highest 7

where as after the increase the lowest value is 5 and the highest nine giving us a range of four

four minis three is one therefore the range increases by one mile

Answer: D: The range will increase by 1 mile.

Step-by-step explanation:

The current range is solved by doing the highest number minus the lowest number, so 7-4. The current range would therefore be 3.

The miles on Monday and Tuesday have been increased by 1 mile, from 4 miles to 5 miles.

The miles on Friday, Saturday and Sunday have been increased by 2 miles, from 7 miles to 9 miles.

You subtract the new values: 9 miles - 5 miles = 4 miles

And subtract your new values from your old range: 4 miles - 3 miles = 1 mile

The range would therefore increase by 1 mile.

-1, -0.10, 0.15, 0.25

So, the answer is the way we do it

-1 , -0.1(or 0.10) , 0.15 , and 0.25

The confidence interval does not justify the councilman's statement because 45 minutes is greater than the upper bound of the confidence interval.

What is a confidence interval?

A confidence interval is a statistical range that is used to estimate an unknown population parameter based on a sample from that population. It is a measure of the degree of uncertainty or precision associated with the estimated value of the parameter.

The confidence interval of 34.42 ± 8.14 minutes means that we are 95% confident that the true population mean commute time falls between 26.28 minutes (34.42 - 8.14) and 42.56 minutes (34.42 + 8.14). Since the councilman's statement of 45 minutes falls outside of this range, we cannot say that it is justified by the confidence interval.

Additionally, the fact that the mean commute time from the sample of 25 adults was 34.42 minutes does not necessarily mean that the true population mean commute time is also 34.42 minutes. It only provides an estimate, and the confidence interval takes into account the variability of the sample mean.

To find the points where the two skaters might collide, we need to find the values of x and y that satisfy both equations simultaneously.

Setting the two expressions for y equal to each other, we get:

-2x + 14 = -2x² + 14x

Simplifying this equation, we get:

2x² - 16x + 14 = 0

Dividing both sides by 2, we get:

This equation can be factored as:

(x - 1)(x - 7) = 0

Therefore, the possible values of x where the skaters might collide are x=1 and x=7.

To find the corresponding values of y, we can substitute each value of x into one of the original equations.

For x=1, we get:

y = -2(1) + 14 = 12

The Screamer could have rotated either about -2.87 degrees or 357.13 degrees from its starting position.

Circumference is the distance around the edge of a closed curve or a circle. It is the length of the boundary of a circular object or shape. In other words, it is the total length of the circular shape.

We can use trigonometry to determine the rotation's angle. The rider's height above the ground is equal to the ferris wheel's radius plus the distance travelled around its circle. Let's call the angle of rotation we're trying to find θ.

The distance traveled along the circumference of the wheel can be calculated as follows:

distance = θ/360 * 2πr

where r is the radius of the wheel. Substituting the given values, we get:

95 = 100 + θ/360 * 2π(100)

Simplifying the equation:

θ/360 = (95-100)/(2π(100))

θ/360 = -0.007957747

θ = -2.8661 degrees or 357.1339 degrees

There are approximately 819 children who weigh between 40 kilograms and 55 kilograms.

What is Standard deviation ?

Standard deviation is a measure of the spread or dispersion of a set of data from its mean. It is calculated as the square root of the variance.

To solve this problem, we can use the properties of a normal distribution, assuming that the weights of the children follow a normal distribution.

We know that the mean weight of 1000 children is 50 kilograms and the standard deviation is 5 kilograms. This means that the weights of the children are distributed around the mean with a spread of 5 kilograms.

We want to find the number of children who weigh between 40 kilograms and 55 kilograms. To do this, we can standardize the values using the standard normal distribution, which has a mean of 0 and a standard deviation of 1. We can use the following formula to standardize the values:

z = (x - μ) ÷  σ

where z is the standard score, x is the raw score, μ is the mean, and σ is the standard deviation.

For x = 40 kilograms:

z = (40 - 50) ÷  5 = -2

For x = 55 kilograms:

z = (55 - 50) ÷ 5 = 1

Now, we can use a standard normal distribution table or calculator to find the area under the curve between z = -2 and z = 1. This area represents the proportion of children who weigh between 40 kilograms and 55 kilograms.

Using a standard normal distribution table or calculator, we find that the area under the curve between z = -2 and z = 1 is approximately 0.8186.

Therefore, the number of children who weigh between 40 kilograms and 55 kilograms is:

0.8186 * 1000 = 818.6 children

Since we can't have a fraction of a child, we round this number to the nearest whole number, which is 819 children.

Therefore,  there are approximately 819 children who weigh between 40 kilograms and 55 kilograms.

By using the P-value method, we conclude that, fewer than half of Americans prefer to watch the news rather than read or listen to it.

What is p-value?

In statistics, the p-value is a probability value that measures the evidence against a null hypothesis. It is the probability of observing a test statistic as extreme as, or more extreme than, the actual test statistic, assuming that the null hypothesis is true.

In this problem, we want to test the claim that fewer than half of Americans prefer to watch the news, based on a poll of 1075 Americans where 46.8% of the respondents said they prefer to watch the news.

Let p be the true proportion of Americans who prefer to watch the news. Then the null hypothesis is:

H0: p ≥ 0.5 (more than or equal to half of Americans prefer to watch the news)

The alternative hypothesis is:

Ha: p < 0.5 (fewer than half of Americans prefer to watch the news)

We will use the normal distribution as an approximation to the binomial distribution, since n = 1075 is large and the success-failure condition is satisfied. The expected number of respondents who prefer to watch the news is:

E = np = 1075 × 0.468 = 503.1

The standard deviation of the sampling distribution of p is:

σ = sqrt[(p(1-p))/n] = sqrt[(0.5×0.5)/1075] ≈ 0.015

We can now calculate the z-score for the sample proportion:

z = (x - E) / σ = (1075 × 0.468 - 503.1) / 0.015 ≈ -4.28

where x is the observed number of respondents who prefer to watch the news, which is 1075 × 0.468 ≈ 503.

The P-value for this test is the probability of getting a z-score less than or equal to -4.28 under the standard normal distribution. Using a standard normal table or calculator, we find that this probability is very close to 0. Therefore, the P-value is less than 0.10, the chosen significance level.

Since the P-value is less than the significance level, we reject the null hypothesis. We have sufficient evidence to conclude that fewer than half of Americans prefer to watch the news rather than read or listen to it.

Answer:

they bought 8 candy bars and 8 + 4 = 12 packs of gum.

Step-by-step explanation:

Let's use algebra to solve this problem:

Let x be the number of candy bars they bought.

Then, the number of packs of gum they bought is x + 4.

The total cost of the candy bars is 60x cents.

The total cost of the packs of gum is 85(x + 4) cents.

We know that they spent $15.00, which is 1500 cents, so we can write an equation:

60x + 85(x + 4) = 1500

Simplifying the equation, we get:

145x + 340 = 1500

145x = 1160

x = 8

Therefore, they bought 8 candy bars and 8 + 4 = 12 packs of gum

Answer: 22

Step-by-step explanation:

The number of the gum is 13 and the number of the candy will be 22.

What is linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Jane and Sophia went to the corner store where packages of gum cost 54¢ each and candy bars cost 88¢ each.

They spent $26.38 total and bought 35 items total.

Let x be the number of the gum and y be the number of the candy.

Then the equation will be

x + y = 35 ...1

0.54x + 0.88y = 26.38 ...2

By solving the equations 1 and 2, then we have

x = 13 and y = 22

Then the number of the gum is 13 and the number of the candy will be 22.

1) The cost of both bands would be equal for 100 students. 2) the fixed cost for the caterer is $150 and the rate per student served is $3. 3) Ticket Price = $4.75 4) you can afford a maximum of 3 bouquets of roses.

Let x be the total number of students in Part 1A.

Band A costs $500.

Band B costs $350 plus $1.50 times.

Part B: By graphing the equations, we can determine the location where the price of the two bands is equal.

$500 = $350 + $1.50x \s$150 = $1.50x \sx = 100

As a result, the price for both bands for 100 students would be the same.

Part 2: Let's solve for the fixed cost and rate per student served using the information provided:

50f + 50r = $450

150f + 150r = $1050

When we deduct the first equation from the second, we obtain:

100f + 100r = $600

F plus R equals $6 when we divide by 100.

The result of replacing the value of f in the first equation is:

50($6 - r) + 50r = $450

$300 - 50r + 50r = $450 \sr = $3

As a result, the caterer's fixed fee is $150, and the cost each student served is $3.

Part 3: For 100 pupils, Band A would cost $500, and Band B would cost $350 plus $1.50 (100) for a total of $500.

Hence, selecting Band A would be more economical. For the dinner dance, each ticket would cost:

Total Price = Band Fee + Caterer Fee

Expense in total is $500 plus ($150 + $3(100)).

Final price: $950

Total Cost / Number of Students x Ticket Price equals $9.50

Band A would cost $500 for 200 pupils, and Band B would cost $350 + $1.50 (200) = $650.

Hence, selecting Band A would be more economical. For the dinner dance, each ticket would cost:

Total Price = Band Fee + Caterer Fee

Expense in total is $500 plus ($150 + $3(200)).

Final price: $950

Total Cost / Number of Students x Ticket Price is $4.75

Step-by-step explanation:

10b = 62 - 12

10b = 50

b = 50/10

b = 5

Answer:

5

Step-by-step explanation:

When trying to find the value of an unknown variable, it is important to take into factors on how to reverse an effect being done to the variable, which is how we can isolate b and figure out the value.

- Addition reverses subtraction

- Multiplication reverses division

We have a simple equation, [tex]10b+12=62[/tex] , and we need to work around the variable b in order to isolate it. By doing this, we are able to find the true value of b.

We can subtract 12 on each side to get the term away from the constant.

[tex]10b+12=62[/tex]

     -   12   -12

[tex]10b=50[/tex]

Then, to isolate the variable from the coefficient, which is 10, we can divide it to negate the multiplication factor on the term.

[tex]\frac{10b}{10} = \frac{50}{10}[/tex]

b=5

Therefore, the variable b=5.
