We can conclude that the width of the rectangular ground is 19ft.

A quadrilateral with all of its angles equal, or right angles, is a rectangle.

In addition to having all equal angles, a square also has all equal sides. Therefore, a special case of a square is a rectangle.

To put it another way, a rectangle can also be a square.

So, we know that:

The perimeter of the rectangular ground is 90ft.

The length of the rectangular ground is 26ft.

Now, the width will be:

Perimeter of rectangle formula: P =  2(l+w)

Now, put the values and substitute as follows:

P =  2(l+w)

90 =  2(26+w)

90 = 52 + 2w

2w = 90 - 52

2w = 38

w = 38/2

w = 19ft

Therefore, we can conclude that the width of the rectangular ground is 19ft.

Answer:

Any bolt length lesser than 4.90 cm or greater than 9.10 cm will be destroyed

Explanation:

Given that:

Mean length = 7 cm

Standard deviation = 1.10 cm

Any bolt outside 2 standard deviations is to be destroyed

The bolt lengths that will be destroyed is obtained as shown below:

This therefore means that any bolt length lesser than 4.90 cm or greater than 9.10 cm will be destroyed

The dimension of data quality being applied in the situation where rounding up to the nearest gram is unacceptable for dosing a drug in milligrams is precision.  

Precision is a dimension of data quality that refers to the level of detail or granularity in the data. In the given situation, it is unacceptable to round up to the nearest gram when dosing a drug in milligrams because grams and milligrams represent different units of measurement with different magnitudes.

Rounding up to the nearest gram would result in a significant loss of precision because it would introduce an error of up to 1000 times the intended dosage. Since milligrams are a much smaller unit than grams, rounding to the nearest gram would not provide the necessary level of accuracy required for proper drug dosage.

To ensure precise dosing in milligrams, the dosage calculations must be performed with appropriate precision, considering the decimal places and milligram units, rather than rounding to a higher unit like grams. By doing so, the dosage can be accurately measured and administered, maintaining the required level of precision in the data.

The radius is half the diameter to just divide the diameter by 2 to find the radius.

Answer:

168

Step-by-step explanation:

We would like to multiply these two expressions together and then substitute -2 in for x to solve.

f(x) * g(x) = (8 - 10x) * (5x + 4)

We will use FOIL (first, outer, inner last):

(8 - 10x) * (5x + 4) = 8 * 5x + 8 * 4 + (-10x) * 5x + (-10x) * 4

Combining terms, we get:

f(x) * g(x) = 32 - 50x²

Plug -2 in for x:

32 - 50 * (-2)² = 32 - 50 * 4 = 32 - 200 = -168

The answer is thus 168.

Answer:

You need to find 84% of 4200 to get the amount of students.  First change the percent to a decimal, and multiply 0.84 x 4200.

There were 3528 total students at the theater.

g(x) = x - 3

f(x) = 2x³

to find g(4), replace x = 4 in g(x) formula, as follows:

g(4) = 4 - 3 = 1

(f+g)(x) = f(x) + g(x) = 2x³ + x - 3

f(0)+g(2) = 2(0)³ + (2) - 3 = 2 - 3 = -1

f(3)+g(0) = 2(3)³ + (0) - 2 = 2(27) - 2 = 54 - 2 = 52

f(-1) -f(1)+g(2) = 2(-1)³ - 2(1)³ + 2 - 3 = 2(-1) - 2(1) + 2 - 3 = -2 - 2 + 2 - 3 = -5

After reducing the given number 40.00 by 5%, the reduced number is, 38

The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.

Formula for percentage;

Percentage = (present quantity/whole quantity)×100

Given that,

The number, 40.00

After reducing it by 5% = ?

5  =  (x/40)×100

x = 2

5% of 40 is 2,

So subtracting it from 40

After decreasing it by 5%

The number = 40-2

                     = 38

Hence, the number is 38

Answer:

  13 refrigerators and 7 pianos will NOT overload the truck

Step-by-step explanation:

For x refrigerators, their total weight is 300x.

For y pianos, their total weight is 525y.

The total weight of both of these together must not exceed 7600, so the inequality is ...

  300x +525y ≤ 7600

__

The point (x, y) = (13, 7) lies in the solution area. The truck will not be overloaded.

__

Check

  300(13) +525(7) = 7575 . . . this is less than 7600

Answer:

Step-by-step explanation:

Represent the number of refrigerators by r and that of pianos by p.

Then the total weight in the truck bed is calculated and we determine whether or not this total is less than the truck capacity.

Find the total weight of the load consisting of 13 refrigerators and 7 pianos.   The inequality given above becomes:

w(r, p) = (300 lb)r + (525 lb)p ≤ 7600 lb

w(13, 7) = (300 lb)13 + (525 lb)7 ≤ 7600 lb becomes:

w(13, 7) = 3900 lb + 3675 lb = 7575 lb

Since 7575 lb is just under the truck's capacity (7600 lb), the truck will not be overloaded.

Answer:

g > -7, f ≤ -5 and g ≥ -5

Step-by-step explanation:

the < and > symbols mean less than and greater than respectively, but not including. Therefore -5 cannot be a valid solution if the range is (for example) g > -5. However, ≤ and ≥ mean less/greater than or equal to, so -5 would be a valid solution for g ≥ -5 (for example).

The factor in the graph that supports the idea that the greater the rainfall in June through August, the fewer acres are burned by wildfires is the negative correlation between rainfall and acres burned.

The graph shows a negative correlation between the amount of rainfall in June through August and the number of acres burned by wildfires. As the amount of rainfall increases, the number of acres burned decreases. This suggests that wetter weather can help reduce the risk of wildfires.

The graph provides a visual representation of the relationship between rainfall and wildfires. It shows that there is a clear negative correlation between the two variables. This means that as one variable increases, the other decreases. In this case, the variable of interest is the number of acres burned by wildfires. The graph shows that when there is less rainfall in June through August, more acres are burned by wildfires. Conversely, when there is more rainfall during these months, fewer acres are burned. This makes sense because rainfall can help reduce the risk of wildfires by making vegetation less dry and therefore less susceptible to catching fire. Additionally, wetter weather can help firefighters contain and extinguish fires more quickly and effectively.

We do 80 times 0.64 (as 0.64 is the percent). This is the same thing as asking for 80% of 60.

Answer: 51.2

Step-by-step explanation:

If you want to find a part out of a number, you use the equation:

Part = Percent x whole

For this equation, you can do 64/100 x 80, because 64% is equal to 64/100

64/100 x 80 = 51.2

You must explicitly state that the null hypothesis is demonstrated to be true in cases where there is insufficient evidence to disprove it.

A statistical hypothesis known as a null hypothesis asserts that no statistical significance can be found in a collection of provided observations. Using sample data, hypothesis testing is performed to judge a theory's veracity. It is sometimes referred to as just "the null," and its symbol is H₀

Even though we are unable to rule out the null hypothesis, this does not always imply that it is accurate. The reason for this is that a hypothesis test cannot tell which hypothesis is true or even which is more likely. It just evaluates whether there is sufficient evidence to disprove the null hypothesis.

The given equation is expressed as

4(x - 3)= 16 - 3x

The first step is to expand the parentheses on the left by multiplying the terms inside the parentheses with the term outside. We have

4x - 12 = 16 - 3x

The nest step is to add 3x and 12 to both sides of the equation. We have

4x + 3x - 12 + 12 = 16 + 12 - 3x + 3x

7x = 28

Dividing both sides of the equation by 7, we have

The following is the null and alternate hypothesis:

H₀ = u = 40.1

H₁ = u < 40.1

The null hypothesis should read as follows if we want to test the assertion that the average workweek has decreased:

The claim that there is a decrease in the typical work week should be made in the alternative hypothesis. The genuine mean is smaller than 40.1 can be used to express this.

The null hypothesis should assert that the average work week has not been significantly reduced, which is the opposite of the alternative. This can be expressed mathematically as 40.1 as the genuine mean.
