Estimate The Quotient Of 88.9 15.1

Answers

Answer 1

88.9 is close to 9015.1 is close to 15The idea of an estimate is to do the math without a calculator. 90 / 15 is roughly 6.

There is something I should say that is critical. If you figure out the exact answer of 5.88, you are likely going to get it wrong. This question asks you to round before you do a division. That's what estimate means.

Answer 2

The diameter of the attic is 18ft and its height is 18ft. What's is the volume of the space in the attic

Answers

I attached an image with the complete question.

Answer:
volume of attic = 1526.04 ft³

Explanation:
Volume of cone can be calculated using the following rule:
Volume = [tex] \frac{1}{3} [/tex] * area of base * height
Volume = [tex] \frac{1}{3} [/tex] * π * radius² * height
We are given that:
π = 3.14
radius = 18/2 = 9 ft
height = 18 ft

Substitute in the equation to get the volume as follows:
Volume = [tex] \frac{1}{3} [/tex] * 3.14 * (9)^2 * (18) = 1526.04 ft³

B.) The mean would increase and the mode would stay the same.

C.) The mode would increase and the mean would stay the same.

D.) The mean would decrease and the mode would stay the same.

Answers

D.) The mean would decrease and the mode would stay the same.

the outlier 77 is much larger than the rest of the numbers. As a result, the mean would decrease because of the outlier if pulling the mean upwards because it is much higher. The mode stays the same because all numbers occur 1 time.

Enter your answer as a fraction, in simplest form, in the box.

Answers

6 numbers rolling a 2 = 1/6
 so rolling something other than a 2 would be 5/6

Answer:  The probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]

Step-by-step explanation:  Given that a number cube has sides numbered 1 through 6. And the probability of rolling a 2 is [tex]\dfrac{1}{6}.[/tex]

We are to find the probability of not rolling a 2.

Let, 'A' denotes the event of rolling a 2.

So, we have

[tex]P(A)=\dfrac{1}{6}.[/tex]

The event of not rolling a 2 is given by the complement of event A.

The probability of the complement of event 'A' can be calculated as

[tex]P(A')=1-P(A)=1-\dfrac{1}{6}=\dfrac{5}{6}.[/tex]

Thus, the probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]

If p=>q and q=> r, which statement must be true?

Answers

Are there any answer choices? The question implies so, otherwise, then p=>r
Final answer:

The condition 'p implies q' and 'q implies r' logically leads to the conclusion that 'p implies r' due to the transitive property of logical arguments, which forms a valid chain argument called syllogism.

Explanation:

Given two conditional statements p⇒q and q⇒r, we can deduce another conditional statement that must logically be true. When p implies q (p⇒q), and q implies r (q⇒r), we can conclude that p⇒r is also true. This is known as the transitive property in logic.

Chain argument or syllogism is a logical argument where a series of premises leads to a conclusion. Using this, when p happens before q, and q precedes r, it follows that p must also lead to r. Therefore, we can construct a logical chain: p⇒q⇒r, resulting in p⇒r.

A scientist is measuring the amount of radioactive material in an unknown substance. When he begins measuring, there are 56.8 grams of radioactive substance. Twelve days later, there are 55.45 grams. After 25 days, there are 54.03 grams. After 41 days, there are 52.32 grams. Assuming that the decay is exponential, find the equation that determines the number of grams remaining after x days and use the equation to determine the amount of radioactive material remaining after 500 days.

2.21 g

12.65 g

2.25 g

20.88 g

Answers

Universal law of radioactive decay states that:
[tex]N=N_0e^{-\lambda t}[/tex]
Where No is an initial number of atoms, N is a number of atoms after time t and lambda is the decay constant. We can use mas of an atom instead of a number of atoms because we know that every atom has the same mass.
[tex]M=M_0e^{-\lambda t}[/tex]
In order to calculate how many atoms are left after 500 days, we need to find decay constant.
We can do this by using the information given in the problem. We know that after 12 days we are left with 55.45 grams and we know the initial amount. With this information we can calculate decay constant:
[tex]M=M_0e^{-\lambda t}\\ 55.45=56.8e^{-12\lambda}\\ 0.976=e^{-12\lambda}\\ ln(0.976)=-12\lambda\\ -0.0243=-12\lambda\\ \lambda=\frac{0.0243}{12}\\ \lambda=0.002[/tex]
Now we simply plug in t=500 and calculate the answer:
[tex]M=M_0e^{-\lambda t}=56.8 e^{-0.002\cdot 500}=56.8e^{-1}=\frac{56.8}{e}=20.88g[/tex]
The final answer is D (20.88g).

X / Y
-2 / -0.35
-1 / -0.3
0 / -0.25
1 / -0.20
2 / -0.15

Answers

The answer is 0.05

-----------------------------------------

Explanation:

Pick any two rows you want. I'm going to pick the first two rows

Row1: x = -2 and y = -0.35
Row2: x = -1 and y = -0.3

Subtract the y values
-0.3 - (-0.35) = -0.3 + 0.35 = 0.05

Subtract the x values in the same order as the y values
-1 - (-2) = -1 + 2 = 1

Divide the differences (y over x)
0.05/1 = 0.05

That's why 0.05 is the answer

a number multiplied by -8, subtracted from the sum of 14 and five times the number

Answers

(14 + 5z) - (-8z) OR (14 + 5z) + (8z)

z= the number

Let us suppose the number is x. Now we try to make an algebraic expression going step by step.

Step 1:

Five times the number means 5 multiplied by x.

So it becomes 5x.

Step 2:

Sum of 14 and five times the number means 5x+14.

Step 3:

Number multiplied by -8 means -8x.

Step 4:

Subtract the expression in step (3) from expression in step (2)

5x+14-(-8x)

Now we can simplify it further,

5x+14+8x

Combining like terms,

13x+14

Answer: The final expression becomes 13x+14.

A probability experiment is conducted wich of these can not be considered a probability of an outcome: 1.015, 0.995, - 0.234, 45%, 2/3, 0.66, 0.45% Can not be considered: 0.995, 45% Can not be considered: 0.995; 0.66 Can not be considered: 1.015, - 0.234 Can not be considered: 0.995; 0.45%; 2/3

Answers

Answers: 1.015, -0.234

Explanation:

The number can only be considered a probability when the number is between 0 and 1. In other words, if the number is either greater than 1, it cannot be considered as probability. Moreover, negative number cannot be considered as probability. 

Since 1.015 is higher than 1, 1.015 is not considered as probability. Also, -0.234 cannot be considered as probability because -0.234 is a negative number. Therefore, 1.015 and -0.234 are not considered as probability.
Final answer:

In probability, the probability of an outcome is a value between 0 and 1, inclusive. From your list, 1.015 and -0.234 do not fall within this range and thus can't be considered as valid probabilities, whilst 45%, 0.45%, 0.995, 2/3, and 0.66 are valid probabilities.

Explanation:

In probability theory, the probability of an outcome is always expressed as a value between 0 and 1, inclusive. In other words, the minimum probability is 0 (representing an event that will not occur) and the maximum is 1 (representing an event that is certain to occur). Probabilities can also be represented as fractions, percentages, or decimal numbers that fall within this range.

Looking at your list, 1.015 and -0.234 cannot be considered valid probabilities, because they fall outside the 0 to 1 range. All percentages should also be converted to decimals before comparison, meaning that 45% is equivalent to 0.45 and is a valid probability, while 0.45% is equivalent to 0.0045 and is also valid. Similarly, 2/3 and 0.66 are valid probabilities because they lie within the 0-1 range.

Write an equation that you can use to solve for x. Enter your answer in the box. Two lines intersect at a point, forming two adjacent angles. One adjacent angle is labeled x degrees and the other adjacent angle is labeled 47 degrees.

Answers

The equation would be x+47=180.

The adjacent angles formed by these two adjacent angles are supplementary; that means that they sum to 180°.

We would solve this by subtracting both sides by 47:
x+47-47=180-47
x=133

Answer: The value of x is 133°.

Step-by-step explanation:

Since we have given that

Two lines intersect at a point forming two adjacent angles.

Measure of one adjacent angle is labeled as = x degrees

Measure of other adjacent angle is labeled as = 47 °

We need to find the value of x in degrees.

As shown in the figure:

Since they are adjacent angles.

So, we can write it as

[tex]x+47^\circ=180^\circ\\\\x=180^\circ-47^\circ\\\\x=133^\circ[/tex]

Hence, the value of x is 133°.
