Answer:
see below
Step-by-step explanation:
We need to find the diameter of the square
We can find this using the Pythagorean theorem
a^2+b^2 = c^2 where the legs are 7 and 7 and the diameter is c
7^2 +7^2 = c^2
49+49 = c^2
98 = c^2
Taking the square root of each side
sqrt(98) = sqrt(c^2)
9.899494937 = c
Since 9.9 is less than 11 which is the diameter of the circle it will never touch the circle.
Since the longest part of the square is less than the diameter of the circle, the square will fit inside the circle without touching
Answer:
Diagonal < Diameter
Step-by-step explanation:
The square will fit inside without touching if the diagonal length is less than the diameter
Diagonal = sqrt(7² + 7²)
7sqrt(2)
Diameter = 11
7sqrt(2) < 11
Because
(7sqrt(2))² < 11²
98 < 121

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

Question:
A company is studying the effects of a new drug on an illness called ataraxia. 100 patients suffering from ataraxia are found. The
company plans to give the new drug to 50 of them and a placebo to 50 of them. The recovery rates for the two groups will then be
compared
1. The division into two groups of 50 should be made randomly. Give an example of how to do this.
2. Why is it important to divide the groups randomly? Explain, and be sure to refer to the terms control, variable, and lurking.
es )
Answer:
1 do the division by a draw of their names into 2 teams
2 there might be one group with a higher age and thus a lower chance of being cured and you should know all variables and have control over the project
Step-by-step explanation:
Answer:
1. There are multiple methods to choosing randomly from a selection. One instance could be choosing names from a hat.
2. Dividing the groups randomly allows for an equal and fair distribution of people for the control and variable groups. The 50 people receiving the drug are the variable group, while the other 50 receiving the placebo are the control group.
Step-by-step explanation:
Random selection is used in testing in order to assure the lack of bias from researchers. In real trials, random selection would likely be done through the company's own software, or an Excel spreadsheet.
Random selection is also used in order to remove lurking variables. An example of a lurking variable could be shown as follows:
A researcher is studying a connection between heart disease and cholesterol intake. Aspects unrelated to the study could still have an effect on the quality of the results, like whether people in the groups smoked or was very stressed. Random distribution assists in removing any lurking variables - and if it can't fully remove them, it will at least distribute them fairly across the control and variable groups.

What’s the least number?
A barrel of candies can be shared equally (without cutting any pieces) among five, six, or eleven children. What is the least number of candies the barrel can contain?
Answer:
the answer is 11 (i think)
Step-by-step explanation:
Answer:
A couple of questions first:
Are we going to divide the candy box equally between those 2,3 or 7 person at one event- (at the same time )?
Are there 12 persons to take into consideration and that each gets the same number of candy pieces?
Are the 3 persons (and the other 2 as well) -different individuals from those who are the 7 referred to . If not then we have to consider 2 more persons.
So does the equal division of candy pieces have to be made between a minimum of 7, 10 or 12 individuals (2+3+7)?
The lowest common denominator is going to be 42. ( 2 x 3 x 7) Therefore seven persons would each get 6 pieces.)
But if the 2 and 3 people are diffèrent persons than the 7 , they will get an equal share ie. 6 pieces each, as well!
2 x 6 = 12
3 x 6 = 18
7 x 6 = 42
So, the box would have to contain at least 72 pieces of candy/ /chocolates or 6 dozens. And every one of the 12 would be happy with his 6 chocolates.

Write the word sentence as an inequality. Then solve the inequality. Three less than a number x is more than 15. An inequality that represents this word sentence is..??? Please help me??
Answer:
x-3>15
x>18
Step-by-step explanation:
usually its better to read it from right to left, more than 15 tells you its gonna be >. then you see 3 less than x, which is x-3. Then solve as if the > was an equal sign
x-3>15
+3 +3
x>18
The inequality representing 'Three less than a number x is more than 15' is x - 3 > 15. Solving this, we get x > 18. Hence, x should be greater than 18.
The word sentence given is: 'Three less than a number x is more than 15'. To write this as an inequality, we start by identifying the mathematical phrase for 'Three less than a number x', which is 'x - 3'.
The phrase 'is more than' translates to the inequality symbol '>'.
Therefore, we set up the inequality as follows:
x - 3 > 15
Next, we solve the inequality step-by-step:
Start with the inequality: x - 3 > 15Add 3 to both sides to isolate x: x - 3 + 3 > 15 + 3This simplifies to: x > 18So, the solution to the inequality is x > 18.
In summary, when converting word sentences to inequalities, ensure you accurately translate the phrases and solve them step-by-step to find the solution.
The dot plots below show the number of hummingbirds spotted per day at two different feeders. The variability at each feeder is 3.168. The difference between the median number of hummingbirds spotted per day at each feeder is approximately how many times the variability?

=> The difference between the median number of hummingbirds spotted per day at each feeder is: 28 -18 =10 and it is = 10 / 3.168
≈ 3 times the variability

Angles 5 and 11, and angles 4 and 6 are pairs of alternate exterior angles.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
Alternate exterior angles are angles that are located on opposite sides of the transversal (a line that intersects two other lines) and outside of the two lines being intersected. They are equal in measure.

Jordan is considering buying her first home. The house she is interested in
buying is priced at $150,000. Jordan qualifies for a 30-year mortgage at 5%.
What will her monthly mortgage payment be?
A) $777.12
B) $697.87
C) $805.23
D) $702.34
Answer:
c
Step-by-step explanation:
Jordan's monthly mortgage payment will be $805.23.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
To calculate Jordan's monthly mortgage payment, we can use the formula for a fixed-payment loan:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
where:
M = monthly mortgage payment
P = the principal, which is the amount borrowed
i = the monthly interest rate, which is the annual interest rate divided by 12
n = the number of monthly payments, which is the loan term in years multiplied by 12
In this case,
the principal (P) is $150,000,
the annual interest rate is 5%,
the loan term is 30 years,
and the monthly interest rate (i) can be calculated as:
i = 5% / 12 = 0.00417
n = 30 years * 12 months/year = 360 months
Substituting these values into the formula, we get:
M = 150000 [ 0.00417(1 + 0.00417)³⁶⁰] / [ (1 + 0.00417)³⁶⁰ – 1 ]
Simplifying this expression, we get:
M = $805.23
Therefore, Jordan's monthly mortgage payment will be $805.23.
