Assume that adults have iq scores that are normally distributed with a mean of 100100 and a standard deviation of 15. find the third quartile upper q 3q3, which is the iq score separating the top 25% from the others.

Answers

Final answer:

The third quartile (Q3) of IQ scores, which separates the top 25% of scores, is approximately 110.125 for a normal distribution with a mean of 100 and a standard deviation of 15.

Explanation:

To find the third quartile (Q3) of IQ scores, which is the value that separates the top 25% from the others in a normally distributed data set, we use the properties of the normal distribution. The mean IQ score is 100 and the standard deviation is 15. Q3 corresponds to the 75th percentile in a normal distribution.

To find the third quartile (Q3), we often refer to the z-score table or use a statistical software or calculator that can handle normal distribution calculations. The z-score corresponding to the 75th percentile is approximately 0.675. We can then use the formula for z-scores:

Q3 = mean + z*(standard deviation)

Q3 = 100 + 0.675*15

Q3 = 100 + 10.125

Q3 = 110.125

Thus, the third quartile IQ score, separating the top 25% of scores from the rest, is approximately 110.125.

To find Q3 for IQ scores (mean 100, SD 15), calculate 75th percentile: [tex]$ Q3 = 100 + 0.674 \times 15 = 110.11 $.[/tex]

To find the third quartile (upper Q3) of IQ scores, we need to determine the IQ score that separates the top 25% from the rest. Given that IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, we can use the properties of the normal distribution to find this value.

1. Identify the z-score corresponding to the third quartile (Q3):

- The third quartile (Q3) corresponds to the 75th percentile of the normal distribution.

- Using the standard normal distribution table or a calculator, the z-score for the 75th percentile is approximately 0.674.

2. Convert the z-score to an IQ score:

- Use the formula for converting a z-score to a value in a normal distribution:

[tex]\[ X = \mu + z \sigma \][/tex]

where:

- [tex]$ \mu $[/tex] is the mean (100)

- [tex]$ \sigma $[/tex] is the standard deviation (15)

- [tex]$ z $[/tex] is the z-score (0.674)

3. Calculate the IQ score:

[tex]\[ Q3 = 100 + (0.674 \times 15) = 100 + 10.11 = 110.11 \][/tex]

Therefore, the third quartile (Q3) IQ score, which separates the top 25% from the others, is approximately 110.

What is the formula for a finite geometric series and how can you use it in a practical situation?

Answers

A finite geometric series is that where the consecutive terms have a fix ratio.

Call r the ratio, An the nth term and An+1 the next term to n, then:

An+1 / An = r

For example, the geometric series, 1, 3, 9, 27, 81, ..

You can verify that

3 = 1* 3
9 = 3 * 3
27 = 9 * 3
81 = 27 * 3

So, the formula is An+1 = An * r, so if you know the first term you can find any other term.

For example, Find the fith term of a geometric series where the first term is 5 and the second term is 25.

r = secont term / first term = 25 / 5 = 5

=> Fifth term = First term * r * r * r * r = First term * r^4 = 25 * 5^4 = 15,625

From this you can also see this valid formula:

An = A1 * r^ (n-1).

So now you have two equivalent formulas:

An+1 = An * r, which is called recursive formula, and
An = A1 * r ^ (n-1), which is called explicit formula

Write the equation in logarithmic form.

25 = 32

A. log32 = 5 • 2

B. log232 = 5

C. log32 = 5

D. log532 = 2

Answers

The equation in logarithmic form is B.log₂32 = 2.

To convert the equation 2⁵ = 32 into logarithmic form, you need to identify the base, the exponent, and the result. The given equation can be interpreted as 2 raised to the power of 5 equals 32.

The general form of a logarithmic equation is: log_base (result) = exponent

In this specific case, we have:

base = 2
result = 32
exponent = 5

Putting it into the logarithmic form, we get: log₂32 = 5

So, the correct option is: B.log₂32 = 2

Line EF has an equation of a line y = −2x + 7. Which of the following could be an equation for a line that is perpendicular to line EF?

y = 2x − 3
y = 1 over 2x − 3
y = −2x − 3
y = −1 over 2x − 3

Answers

1.

When a line is given in the form y=mx+n,

m is the slope of this line.

For example, the slope of the line y=-2x+7 is -2.

2.

If lines y=mx+n and y=kx+t are perpendicular, then the multiplication of their slopes is -1, that is

m*k = -1, so k=-1/m

3.

any line perpendicular to y=-2x+7 has slope = -1/(-2)=1/2

4.

Among the choices, y=(1/2)x-3 is a line perpendicular to the given line.

Answer:

b. y=(1/2)x-3

Answer:

[tex]y=\frac{1}{2} x-3[/tex]

Step-by-step explanation:

Step 1

Find the slope of the line EF

we have

[tex]y=-2x+7[/tex]

The slope of the line EF is equal to

[tex]m=-2[/tex]

Step 2

Find the slope of the line perpendicular to the line EF

we know that

If two lines are perpendicular, then the product of its slopes is equal to minus one

[tex]m1*m2=-1[/tex]

we have

[tex]m1=-2[/tex] -----> slope of the line EF

Find the value of m2

substitute

[tex](-2)*m2=-1[/tex]

[tex]m2=1/2[/tex]

therefore

the equation [tex]y=\frac{1}{2} x-3[/tex] could be an equation for a line that is perpendicular to line EF

If there is a 0.3% chance of something happening one day, what is the possibility of it happening throughout twenty days?

Answers

try by multiplying 0.3x20

You mean of it happening within 20 days?

Well if there is a 3/10 probability of it happening in any given day, there is a 7/10 probability of it not happening on any given day. The probability of it not happening at all in 20 consecutive days is:

(7/10)^20

So the probability of it happening at least once in 20 days is:

Tiffany put a $1550 item on layaway by making a 20% down payment and agreeing to pay $120 a month. How many months sooner would she pay off the item if she increased her monthly payment to $180?
A. 18 months sooner
B. 11 months sooner
C. 4 months sooner
D 7 months sooner

Answers

1550*0.8=1240

1240/120 = approximately 11 months to pay off

1240/180=approximately 7 months to pay off

11-7 =4

so it would be paid off 4 months sooner, so C is the answer

Answer:

Option: C is the correct answer.

C. 4 months sooner.

Step-by-step explanation:

Total amount of the item is: $ 1550

Also, Tiffany paid 20% of the amount by down payment.

Hence, the amount left to pay after the down payment is:80% of total amount.

i.e. 0.80 of total amount.

= 0.80×1550

= $ 1240

Now the number of month it will take if she pay $ 120 a month is:

[tex]=\dfrac{1240}{120}=10.3333[/tex]

which is approximately equal to 11 months.

Similarly, the number of month it will take if she pay $ 180 a month is:

[tex]=\dfrac{1240}{180}=6.8889[/tex]

which is approximately equal to 7 months.

Hence, the number of months sooner she will pay off is:

11-7=4 months.

WE need to write the equation for the given graph

In the graph y intercept is (0,0)

The equation of linear graph is y=mx+b

Find three consecutive odd integers with the sum of 51.

Answers

well.. hmmmm

bear in mind that, if you multiply any integer, odd or even, by 2, you get an even, no matter how you slice it and dice it, you always get an even number, 17 *2, 34*2, or whatever * 2, is always an EVEN integer.

you can always get an ODD integer, by simply adding or subtracting 1 from any even, say 4 - 1, or 4 + 1, is 3 and 5 respectively, both odd ones.

and you can always get another consecutive odd integer, by simply jumping 2 units from any odd, so 3, 5, 7, 9, 11 and so on, notice, you simply hop two spots from one, on either direction back or forth, and you get another ODD integer.

alrite, with that in mind, let's pick a reference value, say "a" is our reference integer.

so, 2*a or 2a, we know is an EVEN integer, however, we also know that 2a + 1 is an ODD integer, well, there you have it, our first odd integer is 2a + 1.

now, let's hop twice from there to get our second consecutive odd one, (2a + 1) + 2, or 2a + 3, now, let's hop again to get the next consecutive odd one, (2a + 3) + 2, or 2a + 5.

there you have it, our reference integer is "a", our odd integers are those.

alrite... now, we know their sum gives 51, alrite

[tex]\bf (2a + 1) + (2a + 3) + ( 2a + 5) = 51 \\\\\\ 2a + 1 + 2a + 3 + 2a + 5 = 51 \\\\\\ 2a + 2a + 2a +1 + 3 ++ 5 = 51\implies 6a+9=51\implies 6a=51-9 \\\\\\ 6a=42\implies a=\cfrac{42}{6}\implies \boxed{a=7}[/tex]

now, recall, "a" is only our reference integer, so... if you want to get the consecutive odd integers, well, they're just 2a + 1, 2a + 3 and 2a + 5, and since you already know what "a" is, well, just plug it in to get the integers.

What is the sum of the arithmetic sequence 3, 9, 15..., if there are 26 terms?

Answers

9 - 3 = 6, 15-9 = 6 the difference is 6, So d = 6

First term: a1 = 3

Sn = n*(a1 + an)/2

Sn = n*(a1 + a1 + (n-1)*d)/2

Sn = n*(2*a1 + (n-1)*d)/2

substitute 26 for n
S26 = 26*(2*a1 + (26-1)*d)/2

substitute 3 for a1

S26 = 26*(2*3 + (26-1)*d)/2

substitute 6 for d

S26 = 26*(2*3 + (26-1)*6)/2

S26 = 2,028

Sum of an arithmetic series is:

S = n*(a_1+a_n)/2, that easy.

n is the number of terms, 26 in your case. a_n is a_26. We need to find the series!

a_n = a_1 + (n-1)*d, the difference, d, is 6.

So a_n = 3 + (n-1)*6 = 6*n-3 (check it works: 3, 9, 15, ...)

Now a_26 = 6*26-3 = 153, so finally:

S = 26*(3+153)/2 = 26*78 = 2028

2028 is the answer
