2. Not only is the mean of pairs of clothes purchased is 10, but the population standard deviation is 4.5. When the researcher from problem number 1 calculates a standard deviation for the distribution of sample means for her 2,950, 000 samples, is the standard deviation of sample means likely to be less than, greater than, or equal to 4.5? Explain
Answer:
Less than 4.5
Step-by-step explanation:
Given that :
Mean = 10
Population standard deviation (σ) = 4.5
Sample size (n) = 2950000
The standard deviation of sample means becomes smaller or lesser as the sample size increases according to the central limit theorem. This is because the standard deviation of sample means is obtained by dividing the population standard deviation by the square root of the sample size. Thus is called the standard error.
The standard deviation of sample means is called the standard error ; and is obtained by:
Standard Error = σ/√n
Standard Error = 4.5 / √2950000
Standard Error = 4.5 / 1717.5564
= 0.0026200

Find the distance between the two points in simplest radical form.
(6, 7) and (8,2)
Answer:
+sqrt(29)
Step-by-step explanation:
Note that the change in x (horizontal leg) is 8 - 6, or 2, and that the change in y (vertical leg) is |2 - 7|, or 5. According to the Pythagorean Theorem, the length of the hypotenuse of the right triangle created here is:
distance = +sqrt(2^2 + 5^2), or +sqrt(29)

the height is 8cm what is the base?
Answer:
b= 15 cm
Step-by-step explanation:
Answer:
15 cm
Step-by-step explanation:
Area of a triangle a = 1/2 * base * height
60 = 1/2 * base * 8
base = 60* 2 / 8 = 15 cm

Answer:
The slope is undefined.
Step-by-step explanation:
A vertical line has undefined, or infinite, slope. If you attempt to find the slope using rise over run or any other slope formula, you will get a 0 in the denominator. Since division by 0 is undefined, the slope of the line is undefined.

32. Use < >, or = to compare 0.36 and 0.4.
Answer:
0.36<0.4
Step-by-step explanation:
Answer:
0.36<0.4
Step-by-step explanation:
the area the arrow swallows is the bigger number so
fore example
0.4 is greater then 0.36 so it would be 0.36<0.4 because the area of the arrow eats or swallows the bigger number
Evelyn jogged 4.5 miles. How many feet did she run?
Answer:
23,760 feet
Step-by-step explanation:
1 mile is 5280 feet, so we multiply both sides of the equation
Answer:
23760 feet
Step-by-step explanation:
1 mile = 5280 feet
4.5 miles x 5280ft = 23760ft
Suppose you choose a number on a piece of paper at random from a bag. The numbers include this set: {7, 9, 10, 11, 12, 13, 14, 15}. There is only one paper for each number, so there are no repeats of the same number. What is the probability that you choose a number less than 10?
Answer:
1/4Step-by-step explanation:
Given the random set of numbers chosen from the bag as {7, 9, 10, 11, 12, 13, 14, 15}
Total outcome = 8 numbers
The numbers that are less than 10 will be the expected outcome, the sets are {7,9}
Expected outcome = 2 elements
Probability = Expected outcome/Total outcome
Pr(that you choose a number less than 10) = 2/8
Pr(that you choose a number less than 10) = 1/4
What’s the perimeter and area?
Answer:
Perimeter= 34a
Area= 42a
Step-by-step explanation:
Perimeter: 3a + 3a + 3a+ 3a +3a + 5a +5a + 9a = 34a
Area: (3a x 9a) + (3a x 5a) = 42a
plz hurry! What is the slope? Draw it on there if you can?
Answer: the answer is 2/3
Step-by-step explanation:
Graph the equation y=x^2-8x+7y=x on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
what points do i need to plot on the graph from this equation please hurry brainlest for whoever can help and 20 points
Answer: If you're plotting 1 equation (y=x^2-8x):
(-4,16) Vertex
(0,0) root
(8,0) root
If plotting both (y=x^2-8x) & (7y=x):
(-4,16) Vertex
(0,0) root
(8,0) root
(7,1) point on line
(-7, -1) point on line
Step-by-step explanation:
The vertex of the parabolic equation y = x² - 8x + 7 will be at (4, -9).
Now, Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = x² - 8x + 7
Convert the equation into a vertex form. Then we have
y = x² - 8x + 7
y = x² - 8x + 16 - 16 + 7
y = (x - 4)² - 9
Hence, The vertex of the parabolic equation y = x² - 8x + 7 will be at
(4, -9).
So, The graph is given below.
More about the equation of the parabola link is given below.

Step-by-step explanation:
Your family is driving to the mountains for the weekend You travel 200 kilometers in the first two hours during the next hour you stop for lunch and only travel 25 kilometers. What is your average speed. Can you please use (D=st)
Answer: (D= 87.5 kilometers per hour)
Step-by-step explanation: First, divide 200 by 2, which equals to 100. Next, divide 25 by 2, which is 12.5. Lastly, subtract 100 minus 12.5, which equals 87.5. You should end up with a result of (D= 87.5 kilometers per hour).
