Answer:
Option (c) is correct.
68% of the data points lie between 10 and 18.
Step-by-step explanation:
Given : a normal distribution with a standard deviation of 4 and a mean of 14
We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.
Since, given 68% data.
We know mean of data lies in middle.
And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.
So, 68% of data lies
mean - standard deviation = 14 - 4 = 10
mean + standard deviation = 14 + 4 = 18
So, 68% of the data points lie between 10 and 18.
The correct sentence for a normal distribution with a standard deviation of 4 and a mean of 14, is that 68% of the data points lie between 10 and 18.
The correct answer is C.
About 68% of the data in a normal distribution lie within one standard deviation of the mean.
● 14−4=10 is one standard deviation below the mean, and
14+4=18 is one standard deviation above it.
Thus, the range of 68% of the data values is between 10 and 18. Option C, which states that "68% of the data points lie between 10 and 18," thus accurately sums up the dataset.
What is the final elevation if a butterfly starts at 20 m and changes -16 m
Answer:
Therefore the final elevation of the butterfly is 4 m.
Step-by-step explanation:
i) initial elevation = 20 m
ii) change in elevation = -16m
iii) therefore final elevation = initial elevation + change in elevation
= 20 m + (-16 m)
= (20 - 16) m
= 4 m
Therefore the final elevation of the butterfly is 4 m.
Answer:
4

Change 6 1/8 into an improper fraction.
Step-by-step explanation:
To find a improper fraction, you must multiply the denominator by the whole number, then add the numerator to the product.
6 x 8 = 48 + 1 = 49.
Our numerator for the improper fraction is 49, we keep the denominator as the same as the whole number fraction, which is 8.
Therefore, your improper fraction is 49/8.
The improper fraction equivalent of 6 1/8 is 49/8.
Given that a mixed fraction 6 1/8, we need to convert it into improper fraction,
To change a mixed number like 6 1/8 into an improper fraction, you need to convert the whole number and the fraction into a single fraction.
Step 1: Multiply the whole number by the denominator of the fraction.
6 x 8 = 48
Step 2: Add the product from Step 1 to the numerator of the fraction.
48 + 1 = 49
Step 3: Write the result from Step 2 over the original denominator.
The original denominator is 8.
Therefore, the improper fraction equivalent of 6 1/8 is 49/8.

Determine the range of the function f(x)=x^2-2/2 when the domain is {0, 2}.
HELP
The range of function is { -1, 1 }
Solution:
Given that, the function is:
[tex]f(x) = \frac{x^2-2}{2}[/tex]
Domain is {0, 2 }
We have to find the range of function
The domain refers to the set of possible input values
The range is the set of possible output values
Here domain is x = 0 and x = 2
Substitute x = 0 in given function
[tex]f(0) = \frac{0-2}{2}\\\\f(0) = \frac{-2}{2}\\\\f(0) = -1[/tex]
Substitute x = 2 in given function
[tex]f(2) = \frac{2^2-2}{2}\\\\f(2) = \frac{4-2}{2}\\\\f(2) = \frac{2}{2} = 1[/tex]
Thus the range of function is { -1, 1 }

Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 5 L, the pressure is 304 kPa (kilopascals). What is the volume when the pressure is 80 kPa ?
Answer:
19 L
Step-by-step explanation:
Given that the volume (V) varies inversely with the pressure (P) then the equation relating them is
V = [tex]\frac{k}{P}[/tex] ← k is the constant of variation
To find k use the condition V = 5 when P = 304
k = VP = 5 × 304 = 1520
V = [tex]\frac{1520}{P}[/tex] ← equation of variation
When P = 80, then
V = [tex]\frac{1520}{80}[/tex] = 19 L

Write as a product of two polynomials.
x(y–5)–y(5–y)
Final answer:
The expression x(y-5) - y(5-y) can be rearranged and factored into (y - 5)(x + y), which is the expression written as a product of two polynomials.
Explanation:
To write the expression x(y-5) - y(5-y) as a product of two polynomials, we first distribute the variables across each term:
x(y-5) = xy - 5x
-y(5-y) = -5y + y²
Now, combining like terms:
xy - 5x - 5y + y²
This expression can't be factored as is, since it cannot be represented by the product of two simpler polynomials with real coefficients. However, we can rearrange the terms:
(xy - 5y) + (y² - 5x) = y(x - 5) + y(y - 5)
Here we can see a common factor of (y-5):
(y - 5)(x + y)
This is the expression written as a product of two polynomials.

The group which represents a success is D. 0, 1, 2, 3, 4, 5.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
a randomly generated list of numbers from 0 to 9 is being used to simulate an event that has a probability of success of 60%.
Total outcomes which are numbers from 0 to 9 = 10
If the probability of success is 60%,
P(success) = 60/100 = 6/10
That is, 6 numbers out of 10 are the outcomes which leads to success.
The correct option is D. 0, 1, 2, 3, 4, 5, which is the only option containing 6 numbers.
Hence the correct option is D.

Find the value of k so that the point A lies on the line given by equation.
A(2, 2), kx+(k+1)y=2
Answer:
k = 0
Step-by-step explanation:
Explanation:-
given straight line equation is k x+(k+1)y=2......(1)
The point A(2,2) lies on the equation is
substitute x = 2 and y=2
k(2) + (k+1)(2) =2
now simplify 2 k+2 k+2 = 2
subtracting '2' on both sides , we get solution is
4 k +2 -2 = 2-2
4 k =0
k = 0
Answer:
k = 0
Step-by-step explanation:
kx + (k + 1)y = 2
2k + 2(k + 1) = 2
2k + 2k + 2 = 2
4k + 2 = 2
4k + 2 - 2 = 2 - 2
4k = 0

Write an algebraic expression for the phrase.
7 inches shorter than 6 times the length x of a table in inches
7x + 6
6x + 7
7x – 6
6x – 7
Step-by-step explanation:
To find, an algebraic expression for the given phrase = ?
6 times the length x = 6x
and
7 inches shorter than 6 times the length x
= 6x - 7
∴ 7 inches shorter than 6 times the length x of a table in inches = 6x - 7
Hence, the required "option d) 6x – 7" is correct.
A triangle has an angle that measures 110°. The other two angles are in a ratio of 2:5. What are the measures of those two angles?
Answer:
20 and 50
Step-by-step explanation:
the angles of a triangle add up to 180 degrees.
so if 1 angle is 110, then the other two angles combined, add up to (180 - 110) = 70.
the other two angles are in a ratio of 2:5....added = 7
meaning 1 angle is 2/7 of total measure and the other angle is 5/7 of the measure
so one angle is : 2/7 of 70 = 2/7 * 70 = 140/7 = 20 <==
and the other one is 5/7 of 70 = 5/7 * 70 = 350/7 = 50 <==

Which descriptions can describe more than one triangle? Select two options.
side lengths of 6 ft, 8 ft, and 10 ft
angle measurements of 35, 35, and 110°
angle measurements of 30°, 40, and 50°
angle measurements of 40°, 60°, and 80°
side lengths of 4 cm, 6 cm, and 9 cm
Answer:
angle measurements of 35, 35, and 110°
angle measurements of 40°, 60°, and 80°
Step-by-step explanation:
we know that
The length sides of a triangle must satisfy the Triangle Inequality Theorem and the sum of their interior angles must be equal to 180 degrees
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
That means, I can have more than one triangle with the same internal angles
so
Verify each description
case 1) side lengths of 6 ft, 8 ft, and 10 ft
Remember that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Applying the triangle inequality theorem
1) 6+8 > 10 ---> is true
2) 6+10 > 8 ---> is true
3) 8+10 > 6 ---> is true
therefore
The description describe only one triangle
case 2) angle measurements of 35, 35, and 110°
The sum of the interior angles is equal to 180 degrees
therefore
The description can describe more than one triangle, by similar triangles
case 3) angle measurements of 30°, 40, and 50°
The sum of the interior angles is not 180 degrees
therefore
The description is not a triangle
case 4) angle measurements of 40°, 60°, and 80°
The sum of the interior angles is equal to 180 degrees
therefore
The description can describe more than one triangle, by similar triangles
case 5) side lengths of 4 cm, 6 cm, and 9 cm
Remember that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Applying the triangle inequality theorem
1) 4+6 > 9 ---> is true
2) 4+9 > 6 ---> is true
3) 6+9 > 4 ---> is true
therefore
The description describe only one triangle
