Step-by-step explanation:
A normally distributed set of data has been generated where 50% of the data lies below 97 and 70% lies below 104. Then, mean of the data is equal to 97 and standard deviation is equal to 13.358.
What is normal distribution?Normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Given that 50% of the data lies below 97, implies that median of the data is equal to 97. In a normal distribution, mean = median = mode, therefore, mean = 97.
Given the mean and value at 70th percentile, we can find the standard deviation.
Using the z score - percentile table, we find that the z score corresponding to the given percentile.
z score corresponding to 70th percentile = 0.524
[tex]0.524 = \frac{x - mean}{standard\ deviation}\\ \\0.524 = \frac{104 - 97}{standard\ deviation} \\\\standard\ deviation = \frac{7}{0.524} = 13.359[/tex]

The length of a rectangular plot of land is 2m more than its breadth. If it's area is 120m^2, find its length and breadth.
Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.

A: Yes, they are equivalent
B: No, they're not equivalent
Answer:
No they are not equivalent.
Step-by-step explanation:
7x + 5 stays the same. You cannot combine them since they aren't like terms.
12x isnt 7x + 5. Therefore no they are not equivalent.
12/14 divided by 7/6 as a fraction
Answer:
[tex] \frac{12}{14} \div \frac{7}{6} [/tex]
[tex] \frac{12}{14} \times \frac{6}{7} [/tex]
[tex] \frac{6}{7} \times \frac{6}{7} [/tex]
[tex] \frac{36}{49} [/tex]
The result of 12/14 divided by 7/6 as a fraction is 36/49.
To divide the fraction 12/14 by 7/6, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction 'a/b' is 'b/a'.
So, the division can be written as:
(12/14) ÷ (7/6) = (12/14) * (6/7)
Now, we can simplify the multiplication:
(12/14) * (6/7) = (12 * 6) / (14 * 7)
Calculate the numerator and denominator:
72 / 98
Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 2:
72 ÷ 2 / 98 ÷ 2 = 36 / 49
Therefore, the result of 12/14 divided by 7/6 as a fraction is 36/49.

Gina deposits $150 at the start of each year into a college savings account that pays 2% simple interest at the end of each year. She does not deposit the interest she earn each year. How much total interest will Gina Earn on her deposit through the end of the fifth year?
Answer:
$45
Step-by-step explanation:
Given the following :
Amount deposited in first year = $150
Interest rate (r) = 2% = 0.02
First year:
Simple Interest = principal * rate * time
= $150 * 0.02 = $3
2nd year:
Principal = $150 * 2 = $300
($300 * 0.02) = $6
3rd year:
Principal = $150 * 3 = $450
($450 * 0.02) = $9
4th year:
Principal = $150 * 4 = $600
(600 * 0.02) = $12
5th year:
Principal = $150 * 5 = $750
($750 * 0.02) = $15
Total interest earned :
$(3 + 6 + 9 + 12 + 15)
= $45

if n^3=x and n^4=20x , where n>0, what is the value of x?
Step-by-step explanation:
∠2 and ∠7 are alternate exterior angles so they are equal.
So you can create the equation
40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.
20x = 100
x = 5
if you need m∠2 Substtute 5 for x in 20x+52
20(5) + 52 = 100 +52 m∠2= 152°
m∠7 40(5) - 48 = 200-48 m∠7= 152°
The value of the variable x is given as 8000.
What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
The given exponential expressions are as below,
n⁴ = 20x
And, n³ = x
Then as per the rule of exponent, the following it can be written as,
n³ = x
⇒ n × n³ = n × x
⇒ n⁴ = nx
⇒ 20x = nx
⇒ n = 20
Then, x = 20³ = 8000
Hence, the value of x is found to be 8000.

A group of friends were working on a student film that had a budget of $800. They spent all their budget on props and equipment. They used 83% of their budget on equipment. How much money did they spend on props?
Answer:
$136
Step-by-step explanation:
100% - 83% = 17%
the 17% is on props.
so, take 17/100 and multiply with $800, which you will get 136.
so the amount of money spent on props is $136

An artist makes necklaces. She packs each necklace in a small jewelry box that is134inches by 214 inches by 34 inch. A department store ordered 270 necklaces. The artist plans to ship the necklaces to the department store using flat-rate shipping boxes from the post office. Which of the flat-rate boxes should she use to minimize her shipping cost?
Answer:
Small flat rate box
Step-by-step explanation:
Since she sells necklaces we can assume that the question is missing spaces and the actual dimensions are 1 3/4inch by 2 1/4 inch by 3/4 inch. This being the case she can use the Small flat rate box from the local post office for her necklaces. This is the smallest flat rate packaging available aside from envelopes, but since the artist needs a 3dimensional box the envelopes would not work. This small flat rate box has the following dimensions 8 11⁄16″ x 5 7⁄16″ x 1 3⁄4″ it also can hold up to 70lbs which far exceeds the weight of the necklaces.
What are the solutions of x2 10x 16 = 0? write the equation in standard form. factor the polynomial. apply the zero product property. solve the resulting equations. x2 10x 16 = 0 (x 2)(x 8) = 0 x 2 = 0 or x 8 = 0 x = and x =
The values of x or the solution of the of provided polynomial equation are x=-2 and x=-8.
What is the factor of polynomial?The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.
The given polynomial equation in standard form is,
[tex]x^2 +10x +16 = 0[/tex]
Now factor the polynomial.
[tex]x^2 +10x +16 = 0\\(x 2)(x 8) = 0[/tex]
Apply the zero product property and find out the factors as,
[tex]x +2 = 0, x +8 = 0[/tex]
Solve the resulting equations by equating both the factors one by one to the zero and find the roots.
[tex]x +2 = 0\\x=-2\\[/tex]

Would it be appropriate to display the data with a pie chart? Yes, because the data are grouped into categories. Yes, because the data can be displayed by a relative frequency compared with the whole. No, because the data display the percentage of time spent by each age group, not a relative frequency compared with the whole. No, because the data categories are too broad.
No, because the data display the percentage of time spent by each age group, not a relative frequency compared with the whole.
The correct option is C.
What is pie chart?
The “ pie chart” is also known as a “circle chart”, dividing the circular statistical graphic into sectors or sections to illustrate the numericical value.
Given
People of different ages were asked the question "Do you listen to audiobooks?
" The frequency table displays the percentage of "yes" responses for different age groups. 13 to 17, 8 percent; 18 to 25, 15 percent; 26 to 35, 23 percent; 36 to 45, 45 percent; 46 and over, 48 percent.
Considering that the data displays the percentage of time spent by each age group, not a relative frequency compared to the whole, a pie chart would not be appropriate.
Pie charts are used to indicate relative frequency of each group, when the whole combines to 100%.In this problem, the sum of the percentages is not 100%, hence, it does not indicate relative frequency, and the third option is correct.Hence, No, because the data display the percentage of time spent by each age group, not a relative frequency compared with the whole.
