Answer:
The correct option is;
A). Randomized block design
Step-by-step explanation:
In a randomized block design the experimental units or subjects of the experiment are separated into subgroups known as blocks with the property that the the variability (difference) of the parameters within the blocks are lesser than the variability between block, such that the treatment of the research or experiment are assigned differently to each block
The groups can therefore comprise of the following;
Group 1
15 men and 15 women to perform water aerobics for 30 minutes twice a week
Group 2
15 men and 15 women to perform water aerobics for 60 minutes once a week
Therefore, the effect of the experiment will be much less attributed to gender than to the durations of the water aerobic exercise.

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

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]
Similarly, for x+8=0,
[tex]x +8 = 0\\x=-8[/tex]
Thus, the values of x or the roots of the equation are,
[tex]x = -2, x =-8[/tex]
Hence, the values of x or the solution of the of provided polynomial equation are x=-2 and x=-8.

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.

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. 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.

What is a circle graph?
A circle graph is used to show information in a circle. The circle is divided into slices which represent a numerical proportion.
Amount spent on food by family A = (14/100) x 5400= $756
Amount spent on food by family B = 16/100) X 4675 = $748
Amount spent on food by family C = (11/100) X6675 = $734.25
Amount spent on transport by family A = (11/100) x 5400= $600.75
Amount spent on transportby family B = 13/100) X 4675 = $607.75
