Answer:1 zip weighs 30 lb

Step-by-step explanation:

3 zowies = 12 lb. so, 1 zowie = 4 lb.

2 zap = 20 lb. so, 1 zap = 10 lb.

1 zip = 30 lb.

One zip weighs 360 pounds.

1. One zip weighs as much as three zaps.

2. Two zaps weigh as much as five zowies.

3. Three zowies weigh as much as two swooshes.

4. One swoosh weighs 60 pounds.

We need to find the weight of one zip.

Step 1: Find the weight of one swoosh.

Since one swoosh weighs 60 pounds, we have:

1 swoosh = 60 pounds

Step 2: Find the weight of three zowies.

Since three zowies weigh as much as two swooshes, and one swoosh weighs 60 pounds, we have:

3 zowies = 2 swooshes = 2 * 60 = 120 pounds

Step 3: Find the weight of two zaps.

Since two zaps weigh as much as five zowies, and three zowies weigh 120 pounds, we have:

2 zaps = 5 zowies = 120 pounds

Step 4: Find the weight of one zip.

Since one zip weighs as much as three zaps, and two zaps weigh 120 pounds, we have:

1 zip = 3 zaps = 3 * 120 = 360 pounds

Answer:

109, 54.4

Step-by-step explanation:

In the circle, the measure of minor arc EF is 109° and the measure of angle DAB is 54.5°.

From the complete information, the line segments EC and FC are radii, angle ECF is 109 degrees while the line segment AD is a chord.

In this case, the measure of minor arc EF will be the value of the angle given which is 109°. Also, the measure of angle DAB will be:

= 1/2 × 109°

= 54.5°

Answer:

5/37.

Step-by-step explanation:

Sum:

3/4 + -4/7

= 21/28 - 16/28

= 5/28

Difference:

3/4 -  (-4/7)

= 3/4 + 4/7

= 21/28 + 16/28

= 37/28.

Dividing:

5/28 / 37/28

= 5/28 * 28/37

= 5/37.

Answer:

Usually pounds (lb) .About an an average of  20 to 25 pounds (lbs)

Step-by-step explanation:

Since Marvin uses Customary units, and considering the Watermelon.

Pounds,  He could estimate based on average of 20 to 25 pounds.

He could choose another customary units, but it wouldn't be practical and unusual to say a watermelon of 160 quarters, also it would leave all the listeners without parameters.

So, definitely pounds.

Okay, we are going to solve this backwards!

First, we need to know that the formula for circumference is

c = π × d

d = diameter

π = 3.14

They told us what the circumference is, so let's plug it in

75 = (3.14) × (d)

let's solve for d

[tex]\frac{75}{3.14} = d[/tex]

d = 23.88 inches

We must remeber that the radius is HALF of the diameter, so let's divide the diameter by 2

[tex]\frac{23.88}{2} = 11.94[/tex]

Now, let's round to the nearest whole inch like they suggested

11.94 ≈ 12

The answer is 12 inches!

Answer: [tex]x=-1[/tex]

Add 8x to both sides

[tex]6x+1+8x=-8x-13+8x\\14x+1=-13[/tex]

Subtract 1 from both sides

[tex]14x+1-1=−13-1\\14x=-14[/tex]

Divide both sides by 14

[tex]14x/14=-14/14\\x=-1[/tex]

Answer:

[tex]6x + 1 = - 8x - 13 \\ 6x + 8x = - 1 - 1 3 \\ 14x = - 14 \\ \frac{14x}{14} = \frac{ - 14}{14} \\ x = - 1[/tex]

Given:

It is given that,

PQ ⊥ PS and

∠QPR = 7x-9

∠RPS = 4x+22

To find the value of ∠QPR.

Formula

As per the given problem PR lies between PQ and PS,

So,

∠QPR+∠RPS = 90°

Now,

Putting the values of ∠RPS and ∠QPR we get,

[tex]7x-9+4x+22 = 90[/tex]

or, [tex]11x = 90-22+9[/tex]

or, [tex]11x = 77[/tex]

or, [tex]x = \frac{77}{11}[/tex]

or, [tex]x = 7[/tex]

Substituting the value of [tex]x = 7[/tex] in ∠QPR we get,

∠QPR = [tex]7(7)-9[/tex]

or, ∠QPR = [tex]40^\circ[/tex]

Hence,

The value of ∠QPR is 40°.

{(-2, -3), (-3, -2), (2,3), (3, 2)}

Step-by-step explanation:

A function is a set of ordered pairs in which no two pairs have the same first number.

In other words, an x cannot be paired with two y's.

A function takes an x and pairs it with one and only one y.

{(0,0), (0, 2), (2.0), (2, 2)} is not a function because it pairs 0 with both 0 and 2.

{(2,-1), (2, 1), (3,-1), (3, 1)} is not a function because it pairs 2 with both -1 and 1.

{(2, 2), (2, 3), (3, 2), (3, 3)} is not a function because it pairs 2 with both 2 and 3.

The height of a cylinder is twice the radius of its base.

Let the height of the cylinder = 2x

Let the radius of the cylinder = x

By formula, volume of the cylinder = π[tex]r^{2}[/tex] h

here r = x, h = 2x

substituting the values in the equation, we get

volume of the cylinder = π[tex]r^{2}[/tex] h =  π [tex]x^{2}[/tex] (2x)

volume of the cylinder = 2π[tex]x^{3}[/tex]

The expression that represents the volume of the cylinder is 2x³π.

A cylinder is a three-dimensional object that is made up of a two circles that are attached to a rectangle.

Volume of a cylinder = πr²h

Answer:

Step-by-step explanation:

Confidence interval is constructed to provide an estimated for an unknown population parameter such as the mean and sometimes, the standard deviation. It is expressed as

Sample mean ± margin of error

From the confidence interval given, the lower boundary is 76.6 grams while the upper boundary is 90.1 grams. Therefore,

It means that we are 95% confident that the mean weight of all clementines at the store lies between 76.6 grams to 90.1 grams. Also, 95% of the confidence intervals constructed in this way would contain the true value for the population mean weight of all clementines at the store.

Final answer:

A 95% confidence interval for the mean weight of clementines at a local grocery store ranging from 76.6 to 90.1 grams means we are 95% confident the true average weight of all clementines falls within this range. This range is based on a random sample and provides an estimate of the population mean. The width of the interval reflects the estimate's precision.

Explanation:

A 95% confidence interval for the mean weight of clementines, which ranges from 76.6 grams to 90.1 grams, means that we are 95% confident that the average weight of all clementines available in the store falls within this range. This interval was determined based on a random sample of clementines purchased, which serves as a representative subset of the entire clementine population in the store.

The concept of a confidence interval allows researchers and statisticians to estimate the true mean of a population based on sample data. In this case, unless the true average weight of the clementines lies outside this range, which has only a 5% probability (100% - 95%), we can assume that our interval includes the true mean weight of all clementines in the store. This interpretation is common in statistics and is crucial for making informed decisions or predictions based on sample data.

The width of the confidence interval, from 76.6 to 90.1 grams, reflects the precision of our estimate. A narrower interval would indicate a more precise estimate of the true mean weight, but increasing precision usually requires a larger sample size or a more homogeneous population. The principles behind confidence intervals are fundamental in various fields, including scientific research, engineering, and business analytics, to make reliable inferences about population parameters based on sample statistics.

The addition of 3a^2 + a^2 to a + 6 gives 3a^2 + a^2 + a +6.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

We have to find when 3a^2 + a^2 added to a + 6.

3a^2 + a^2 + a +6

This cannot be added further because they do not have any like terms.

Since those terms are not like terms, their coefficient won't be add and the expression we've got right now, is its simplest form and cannot be reduced more.

Those terms which have same variables raised with same power are like terms.

For example, 5t^3 and 6t^3 are like terms since variable is same, and it is raised to same power 3.

Thus, the addition of 3a^2 + a^2 to a + 6 gives 3a^2 + a^2+ a +6
