The solution of 87e0.3x = 5918, to the nearest
thousandth, is
A. 0.583
B. 1.945
C. 4.220
D. 14.066
Answers
Answer:
\(D) ~ 14.066\)
Step-by-step explanation:
\(~~~~87e^{0.3x} = 5918\\\\\implies e^{0.3x} = \dfrac{5918}{87}\\\\\implies \ln\left(e^{0.3x} \right)=\ln \left( \dfrac{5918}{87} \right)\\\\\implies 0.3x \ln e = \ln \left( \dfrac{5918}{87} \right)\\\\\implies 0.3x = \ln \left( \dfrac{5918}{87} \right)\\\\\implies x = \dfrac{\ln \left( \dfrac{5918}{87} \right)}{0.3}\\\\\implies x \approx14.066\)
How can you turn any number into a science notation?
Please help me it would mean the world!
Answers
Answer/Step-by-step explanation:
To turn any number into a science notation is first write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
[RevyBreeze]
Consider the 4-digit number abcd. Putting it in scientific notation is a matter of moving the (invisible) decimal point to the left until you have a number between 1 and 10, then multiplying this number by an appropriate power of 10, equal to the number of positions that the point was moved.
In this case,
abcd = abcd . = a . bcd × 10³
The number of underlined digits is the number of positions you have to move the decimal point. The number a . bcd is called the mantissa.
For a number already containing a decimal point, like abc . def, we do the same thing:
abc . def = a . bcdef × 10²
For a number smaller than 1, such as 0.000abcd, we have to move the decimal to the right:
0.000abcd = 0000a . bcd = a . bcd × 10⁻⁴
As mentioned earlier, the mantissa is typically supposed to be between 1 and 10, which means that if you start with a number larger than 1, that number in scientific notation will involve multiplication by a positive power of 10. On the other hand, if you start with a number smaller than 1, the power of 10 will be negative. You can see this is true for each of the examples I've used here.

How many positive integers between 1000 and 9999 inclusive are divisible by 5 and 7?
Answers
If a number is divisible by 5 and 7, then that number is divisible by LCM(5, 7) = 35. So count the multiples of 35 in the range.
Since
9999 = 35•285 + 24
we know there are 285 multiples of 35 among the positive integers 1-9999. We also have
1000 = 35•28 + 20
so there are 28 multiplies of 35 less than 1000.
Then there are 285 - 28 = 257 multiples of 35 in the given range.
Seventeen less than three times a number is less than four times the number decreased by nine.

Anna has a loyalty card good for a 7% discount at her local grocery store. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?
Answers
Anna should multiply the prices on the tags by 0.93 to find the price she would have to pay before tax in one step.
Given that Anna has a loyalty card good for a 7% discount at her local grocery store.
We have to find the number should she multiply the prices on the tags by to find the price she would have to pay, before tax
Anna should multiply the prices on the tags by 0.93 (which is 1 minus the 7% discount) to find the price she would have to pay before tax in one step.
For example, if an item costs $10 before the discount, Anna would pay $10 x 0.93 = $9.30 after the discount.
Hence, Anna should multiply the prices on the tags by 0.93 to find the price she would have to pay before tax in one step.

Which of the following questions cannot be answered by a structural model? a) What is the direction and influence between latent variables? b) What is the nature of latent variables - continuous or non-continuous? c) What is the is the causal and effect relationship between latent variables? d) is the theory consistent with the hypothesized relationships?
Previous question
Answers
The question that cannot be answered by a structural model is "b) What is the nature of latent variables - continuous or non-continuous?"
A structural model, also known as a path analysis or causal model, is used to examine the relationships between variables and determine the causal effects between them. It allows researchers to understand the direction and influence between latent variables (a), the causal and effect relationship between latent variables (c), and whether the theory is consistent with the hypothesized relationships (d). However, the nature of latent variables, whether they are continuous or non-continuous, is not a question that can be answered by a structural model alone. The nature of variables, such as whether they are continuous or discrete, is determined based on the measurement scale and characteristics of the variables, which is typically addressed in the measurement model component of a structural equation model. To understand the nature of latent variables, additional analysis and considerations, such as examining the distribution of the observed indicators or conducting measurement validation, are required. Therefore, this question cannot be directly answered by a structural model.

Caroline works in a department store selling clothing. She makes a guaranteed salary
of $200 per week, but is paid a commision on top of her base salary equal to 25% of
her total sales for the week. How much would Caroline make in a week in which she
made $1575 in sales? How much would Caroline make in a week if she made a dollars
in sales?
Answers
The amount made by Caroline is $593.75 and 200 + 0.25x when she made $1574 and $x in sales respectively.
The total amount will be given by the formula using percentage -
Total amount = Base salary + 25% × her total sales
Keep the value in equation when she made $1575
Total amount = 200 + 25% × 1575
Total amount = 200 + 393.75
Total amount = $593.75
Keep the value in equation when she made $x
Total amount = 200 + 25% × x
Total amount = 200 + 0.25x
Hence, the earned amount is $593.75 and 200 + 0.25x.

Answers
There is a \(0.54\) probability that Bryan will choose a ham- or turkey-on-wheat sandwich at random.
What is likelihood and how is it calculated?The probability measures the likelihood of an event happening. It gauges how likely an occurrence is. P(E) = Number of Favorable Results of Total Outcomes is the formula for probability.
Who founded probability?Blaise Pascal with Pierre de Fermat, two eminent mathematicians, exchanged correspondence in the middle of the 17th century that provided the groundwork for probability and altered how mathematicians and researchers perceived uncertainty and risk.

As a result, the following is the experimental likelihood of choosing a turkey or ham sandwich at random:
\(13+ 24=0.54\)

We have that:

So, to get x, we can find the cube root of both sides:
\(\begin{gathered} \sqrt[3]{x^3}\text{ = }\sqrt[3]{\frac{64}{27}} \\ \Rightarrow\text{ x = }\sqrt[3]{\frac{4\cdot4\cdot4}{3\cdot3\cdot3}} \\ x\text{ = }\frac{4}{3} \end{gathered}\)That is the value of x.

The opposite side of the right triangle (x) is approximately 6.888 inches long.
Right angle triangleTo solve this problem, we can use the trigonometric ratio for the sine function, which is opposite/hypotenuse. We have the hypotenuse as 12 inches and the opposite angle as 35 degrees, so we can set up the equation:
sin(35) = opposite/12
To solve for the opposite, we can multiply both sides by 12:
opposite = 12 * sin(35)
sin(35) as approximately 0.574:
opposite = 12 * 0.574
opposite ≈ 6.888
Therefore, the opposite side of the right triangle (x) is approximately 6.888 inches long.

The length of line segment DE is 10 units
A line CE is given, on which three points C, D and E lies in such a way that
length of line segment CD = 20
length of line segment CE = 32
We need to find the length of line segment DE
We know from the property of a straight line that, sum of all the length of line segments of a line is equal to the total length of the straight line
Therefore, CD + DE = CE
Putting values, we will get
20 + DE = 32
DE = 32 -20
DE = 10

Answer:

Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here RS is the hypotenuse and the legs have measure 5 and 3, thus
RS² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )
RS = \(\sqrt{34}\) ≈ 5.83 ( to 3 significant figures )
