Answer: 26.7
First, you must remove the percentage sign, then you will get a equivalent decimal.
When we remove the % sign, we get 26.7.
The answer is 26.7. Hope this helps!
It is found that 26.7% as an equivalent decimal is 0.267.
LEt the value of which a thing is expressed in percentage is "a' so the percent that considered thing is of "a" is b%
However percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
To convert 26.7% to an equivalent decimal, we simply divide it by 100:
26.7% ÷ 100
26.7/ 100 x 100 = 0.267
Therefore, WE can conclude that 26.7% as an equivalent decimal is 0.267.

A population is normally distributed with a mean of 100 and a standard deviation of 10. For samples of size 25, what is the probability of randomly sampling and finding a sample mean of 99 or more
Answer:
The value is [tex]P( \= X \ge 99) = 0.69146[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 100[/tex]
The standard deviation is [tex]\sigma = 10[/tex]
The sample size is n = 25
The standard deviation of the sampling distribution is
[tex]\sigma_{\= x} = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x} = \frac{10}{\sqrt{25} }[/tex]
=> [tex]\sigma_{\= x} = \frac{10}{5 }[/tex]
=> [tex]\sigma_{\= x} = 2[/tex]
Generally the probability of randomly sampling and finding a sample mean of 99 or more is mathematically represented as
[tex]P( \= X \ge 99) = 1 - P(\= X < 99)[/tex]
Here
[tex]P(\= X < 99) = P(\frac{\= X - \mu }{\sigma } < \frac{99 - 100 }{2} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(\= X < 99) = P(Z < -0.5 )[/tex]
From the z table probability of (Z < -0.5 ) is
[tex]P(Z < -0.5 ) = 0.30854[/tex]
Generally
[tex]P( \= X \ge 99) = 1 - 0.30854[/tex]
=> [tex]P( \= X \ge 99) = 0.69146[/tex]
The temperature fell 36oF in 9 hours. If the temperature fell at the same rate every hour, which represents the change in temperature each hour?
Answer:
4°F
Step-by-step explanation:
If the temperature fell 36°F in 9 hours, then;
36°F= 9hours
to get the change in temperature in 1 hour, we will say;
x°F = 1 hr
Since we have
36°F= 9hours
x°F = 1 hr
Cross multiply
9x = 1*36
9x = 36
x = 36/9
x = 4°F
Hence the change in temperature each hour is at 4°F

Answer:
Given: total of 810 miles
Judy's miles = x
Susan's miles = 2x
Solution:
Solve for Judy's miles
2x + x = 810 miles
3x = 810 miles
(transpose) x= 810 miles / 3
x = 270 (Judy drove 270 miles)
Solve for Susan's miles
2x = Susan's miles
2(270 miles) = 540 miles
Answer: Susan drove for 540 miles
Answer:
Given: total of 810 miles
Judy's miles = x
Susan's miles = 2x
Answer: Susan drove for 540 miles
Step-by-step explanation:
Solution:
Solve for Judy's miles
2x + x = 810 miles
3x = 810 miles
(transpose) x= 810 miles / 3
x = 270 (Judy drove 270 miles)

A component is assembled in a four-step process. The probability of making a defect in step 1 is .10; in step 2, .20; in step 3, .08; and in step 4, .05. What is the probability that the component will be defective
Answer:
0.371
Step-by-step explanation:
Given that:
Assembly requires a 4 step process:
Probability distribution of defect :
P(step 1) = 0.1
P(step 2) = 0.2
P(step 3) = 0.08
P(step 4) = 0.05
Firstly, we find the probability that there is no defect in each of the assembly process :
Probability of no defect: = (1 - p(defect))
P(step 1) = 1 - 0.1 = 0.9
P(step 2) = 1 - 0.2 = 0.8
P(step 3) = 1 - 0.08 = 0.92
P(step 4) = 1 - 0.05 = 0.95
Hence,
P(no_defect) = 0.9 * 0.8 * 0.92 * 0.95 = 0.62928
Probability of having a defective component ;
P(defect) = P(no_defect)' = 1 - p(no-defect)
1 - 0.62928 = 0.37072
0.37072
= 0.371

There are 111 students in a nutrition class. The instructor must choose two students at random. What is the probability that a senior Nutrition major and then a junior Nutrition major are chosen at random
Complete Question
The complete question is shown on the first uploaded image
Answer:
The value is [tex] P(k \ n \ u ) = 0.02957[/tex]
Step-by-step explanation:
From the question we are told that
The total number of students is n = 111
The total number of senior nutrition major k = 19
The total number of junior nutrition major is u = 19
Generally the probability that a senior Nutrition major and then a junior Nutrition major are chosen at random is mathematically represented as
[tex]P(k \ n \ u ) = P(k) * P(u\ | \ k)[/tex]
Here [tex]P(k)[/tex] is the probability that a senior nutrition major is selected , this is mathematically represented as
[tex]P(k) = \frac{k}{n}[\tex]
=> [tex]P(k) = \frac{ 19}{111}[\tex]
and P( u | k) is the probability that a junior Nutrition major is selected given that a senior nutrition major has already been selected and this is mathematically represented as
[tex]P( u | k) = \frac{u}{n-1}[/tex]
=> [tex]P( u | k) = \frac{19}{111-1}[/tex]
=> [tex]P( u | k) = \frac{19}{110}[/tex]
So
[tex] P(k \ n \ u ) = \frac{ 19}{111} * \frac{19}{110} [/tex]
=> [tex] P(k \ n \ u ) = 0.02957[/tex]
A reasonable estimate of the product is 280 true or false

Of the following, which statement or statements accurately reflect a way in which credit can be safer than cash?
1. If your credit card gets stolen, you can cancel it and get your money back.
II. It is harder to lose a single credit card than a large number of bills.
III. If a merchant does not honor the agreement, you can call the credit company and dispute the charges.
A.I and III
B.ll only
C.Ill only
d. 1, 11, and 111
Please select the best answer from the choices provided.
===================================================
Explanation:
Statement I is true. If your card gets stolen, then you can cancel it and get your money back. That's true and it happens all the time. The credit card company would issue a new card with a new number. Law enforcement is very likely to track the old card to catch the thief. Statement II is false. It's easier to lose a single small credit card than a large number of bills. Lost credit cards, not necessarily stolen ones, are also issued new replacements. Statement III is true. If you buy an item online for instance, and the item never arrives, then you can dispute the claim and get your money back. This also applies to payment processors such as Paypal and similar companies.Louis is a gardener. He plants 4 rose bushes for every 3 lilac bushes. If Louis

Step-by-step explanation:
Answer:
See attached image for the graph
Step-by-step explanation:
Start by finding at least two points on the plane that satisfy the equation, and join them with a line.
Pick good values for "x" that will make the evaluation easy (for example the number "0" and also multiples of "3":
when x = 0 then y = 0/3 - 4 = -4 then the point is (0, -4)
when x = 3 then y = 3/3 -4 = 1 - 4 = -3 then this new point is (3, -3)
when x = 6 then y = 6/3 - 4 = 2 - 4 = -2 then a third point is (6, -2)
We plot these points on the plane, and join them with a line, s shown in the attached image.

What are terms with the same variable raised to the same exponent?
Answer:
Like terms are the terms with the same variable raised to the same exponentThe term used for the same variable raised to the same exponent is called Like terms.
What are exponents?
An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6.
Given that, What are terms with the same variable raised to the same exponent
Like terms are the terms that contain the same variables raised to the same power, the coefficients need not be the same. For example, 7x and 2x are like terms because both terms contain the same variable "x"
Hence, The term used for the same variable raised to the same exponent is called Like terms.

What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
here,
In the question, 4 number line given with a number of point marked in blue representing the solution of the expression |x - 5| = 1, we have to determine the number which shows the correct solution of the given expression,
so,
Simplifying the given expression,
|x - 5| = 1
Since when we Un-mode the expression implement the ± on the other side.
x - 5 = ± 1
Case 1, taking (+)
x - 5 = 1
x = 6
Cae 2, taking (-),
x - 5 = -1
x = -1 + 5
x = 4
Thus, the required number line that shows the solution of the given expression is the line that has blue points on numbers x = 4 and x = 6.

Answer:
6(x+2)(x-5)
Step-by-step explanation:
This is factoring trinomials, so x^2+ bx+c. In order to this you need to find two integers whose product is c and whose sum is b. Rewrite the trinomial as x2 + rx + sx + c and then use grouping and the distributive property to factor the polynomial. The resulting factors will be (x + r) and (x + s).
Step-by-step explanation:
6x^2 - 18x - 60 reducing it to a simplest form:
x^2 - 3x - 10
(x^2 - 5x) + (2x - 10)
x(x - 5) + 2(x - 5)

Step-by-step explanation:
1) Statisticians always prefer larger samples sizes to small ones. Describe the effect of increasing the size of a sample (the number of participants in an experiment) from 25 to 100 on the following, assuming the mean and standard deviations of the samples remain constant: (6 pts) a. How would the margin of error of a 95% confidence interval change
Answer:
The margin of error reduces to half of it original size
Step-by-step explanation:
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
Let assume the standard deviation is [tex]\sigma = 0.4[/tex]
When sample size is n = 25
[tex]E = 1.96 * \frac{0.4 }{\sqrt{25} }[/tex]
[tex]E =0.1568[/tex]
When sample size is n = 100
[tex]E_1 = 1.96 * \frac{0.4 }{\sqrt{100} }[/tex]
[tex]E_1 = 0.0784 [/tex]
So
[tex]\frac{E_1}{E} = \frac{0.0784}{0.1568} = \frac{1}{2}[/tex]
Hence the margin of error reduces to half of it original size
