With 98% confidence interval and n = 25. Find left critical value for Zinterval.
0 -2.492
0 -2.05
0 -2.797
-2.326
Answer:
[tex]\alpha=1-0.98 =0.02[/tex]
And [tex]\alpha/2 0.01[/tex], the degrees of freedom are given by:
[tex] df= n-1= 25-1=14[/tex]
Then the critical value using the t distribution with 24 degrees of freedom is:
[tex] t_{\alpha/2}= \pm 2.492[/tex]
And the best solution would be:
0 -2.492
Step-by-step explanation:
For this problem we know that the sample size is n = 25. The confidence level is 98% or 0.98 then the significance would be:
[tex]\alpha=1-0.98 =0.02[/tex]
And [tex]\alpha/2 0.01[/tex], the degrees of freedom are given by:
[tex] df= n-1= 25-1=14[/tex]
Then the critical value using the t distribution with 24 degrees of freedom is:
[tex] t_{\alpha/2}= \pm 2.492[/tex]
And the best solution would be:
0 -2.492
mean median and mode of 50 2 36 12 40 10 14 27 13 3 36 10 9 34 42 1 24 154 4 21 31 7 4 12 3 31 8 3 24 66 3 22 52 2 25 5 14 29 48 4
Answer:
The mean is the average of a set of numbers. To calculate mean, you would add up all the numbers, then divide by how many numbers there are.
50 + 2 + 36 + 12 + 40 + 10 + 14 + 27 + 13 + 3 + 36 + 10 + 9 + 34 + 42 + 1 + 24 + 154 + 4 + 21 + 31 + 7 + 4 + 12 + 3 + 31 + 8 + 3 + 24 + 66 + 3 + 22 + 52 + 2 + 25 + 5 + 14 + 29 + 48 + 4 = 935
There are 40 numbers in the set, so you would divide by 40.
935 ÷ 40 = 23 15/40 = 23.375
So, the mean is 23.375.
The median is basically the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number.
1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 7, 8, 9, 10, 10, 12, 12, 13, 14, 14, 21, 22, 24, 24, 25, 27, 29, 31, 31, 34, 36, 36, 40, 42, 48, 50, 52, 66, 154
So, the median is 14.
The mode is the number that appears the most often in a set of numbers.
3 appears 4 times in this set of numbers.
So, the mode is 3.
Answer:
Mean: 23.82
Add these numbers together 1, 2, 3, 3, 3, 3, 4, 4, 4, 5, 7, 8, 9, 10, 10, 12, 12, 13, 14, 14, 21, 22, 24, 24, 25, 27, 29, 31, 31, 34, 36, 36, 40, 42, 48, 50, 52, 66, 150
=929
Then divide by the amount of numbers : 39
929/39 = 23.820512
Median: 14
Arrange the numbers is least to greatest.
Find the number in the middle of the set.
Mode: 3
Find what number occurred the most in the set.
how would i do number 2?
Answer:
m=2
Step-by-step explanation:
When you put a number into the inverse of a function (f^-1) you get the original number back.
Ex: f^-1(11) = (11-3)/2 = 4
f(4) = 2×4+3 = 11
So, f(-5)=-2
So, when x is -5,
f(x) = -2
f(x)=m(-5)+8
-2=m(-5) + 8
m=2

Answer:
2.35 m²
Step-by-step explanation:
Divide the shape into shapes you can calculate the area of: a rectangle with a semi-circle on top, minus a square.
1. Calculate the area of the rectangle. Formula for area of a rectangle is length · width
1 m · 2 m = 2 m²
2. Calculate the area of the semi-circle. Formula for a semi-circle is [tex]\frac{\pi r^{2} }{2}[/tex] (use 3.14 for π) (radius is equal to half the diameter)
3.14(0.5)² = 0.785
0.785 ÷ 2 = 0.3925 m²
3. Combine the total area
2 + 0.3925 = 2.3925
4. Calculate the area of the square that will not be painted. Formula for area of a square is s² (side · side)
0.2² = 0.04 m²
5. Subtract the area of the square from the total area
2.3925 - 0.04 = 2.3525
2.3525 rounds to 2.35 m²

hi :) how to do question 7 ?
Answer:
Step-by-step explanation:
We khow that the equation of a circle is written this way :
(x-a)²+(y-b)²=r² where (x,y) are the coordinates of the cercle's points and (a,b) the coordinates of the cercle's center and r the radius .
Our task is to khow the values of a and b :
We khow that the center is lying on the line 3x+2y=16⇒ 2y=-3x+16⇒ y= [tex]\frac{-3}{2}[/tex]x+8 We khow that the points P and Q are two points in the cercle Let Ω be the center of this cercle we can notice that : PΩ AND QΩ are both equal to the radius ⇒ PΩ=QΩ= rSo let's write the expression of this distance using vectors KHOWING THAT Ω(a,b)Vector PΩ(a-4,b-6) and Vector QΩ(a-8,b-2) PΩ=[tex]\sqrt{(a-4)^{2}+(b-6)^{2} }[/tex] and QΩ=[tex]\sqrt{(a-8)^{2}+(b-2)^{2} }[/tex] Let's substitute a by x and b by y PΩ=QΩ we substitute each distance by its expression After simplyfying the expressions we get finally : -12+8x-8y=0 now we have -12x +8x-8y=0 and the line equation 3x+2y-16=0 these are simultanious equations so after solving them we get x=3.8 wich is approximatively 4 and y=2 we substitute a by 4 and y by 2 in PΩ to get the radius we get r = [tex]\sqrt{(4-4)^{2}+(2-6)^{2} }[/tex] = 4 so r²= 16 then the equation is : (x-4)²+(y-2)²=165*2568?252+2626*25625-26236

The expression 14s(s - 1) can be used to find
the total number of cards created by the ninth
grade students. Based on the given information,
which of the following statements must be true?
Select all that apply.
Answer:
B. The variable s represents the number of students in each class.
C. The coefficient 14 represents the number of classes in the 9th grade.
Step-by-step explanation:
The total number can be found by multiplying the number of the things with the number of people producing it. For example if 5 boys make 5 colored ropes the total number of ropes will be 5*5= 25.
In this question the combinations rule is used for variuos number of classes which are 14. Now we have to find the number of students which are s (s-1). Suppose s= 6 so the number of students would be 6(6-1) = 6(5) = 30
We will multiply the number of classes 14 with the number of students s(s-1) to get the total number of cards produced.
Lewis Hamilton completed the first lap at the Monaco Grand-Prix with an average speed of 125 mi/h. His goal is to complete the first two laps with an average speed of 250 mi/h. How fast (in terms of average speed) should his second lap be?
Answer:
infinitely fast
Step-by-step explanation:
To have double the average speed, he must complete the two laps in the same amount of time that he spent completing the first lap. That is, he must complete the second lap in zero time.
Hamilton's average speed for the second lap should be infinite. (He needs to finish it in zero time.)
_____
speed = distance/time
Multiplying by 2, we get ...
2×speed = 2×distance/time . . . . . the time hasn't changed
Which answer is equal to i^45
Answer:
i
Step-by-step explanation:
The pattern is as follows
i^1 = i
i^2 = -1
i^3 = -i
i^4 = 1
Following this pattern, i^45 = i.
The value of the expression [tex]i^{45[/tex] is equal to i
Complex numbers are the square root of negative numbers. For instance:
[tex]\sqrt{-1} = i\\i^2 = -1[/tex]
Given the complex number:
[tex]i^{45}\\= (i^2)^{22} \times i\\= (-1)^{22} \times i[/tex]
Since any value raise to the even values will give a positive value hence;
[tex]=(-1)^{22} \times i\\=1 \times i\\= i[/tex]
This shows that the value of the expression [tex]i^{45[/tex] is equal to i

What is a number of subsets for the set which contains the 10 elements.
Answer:
The number of subsets of a set containing 10 elements is 2^10=1024.
Step-by-step explanation:
The function represented by graph B is g(x) = _________
The function represented by graph C is h(x) = _________
Answer:
[tex]g(x)=\sqrt[3]{x-1}[/tex]
[tex]h(x)=\sqrt[3]{x}-1[/tex]
Step-by-step explanation:
Graph represents the parent function
[tex]f(x)=\sqrt[3]{x}[/tex]
The translation is defined as
[tex]g(x)=f(x+a)+b[/tex]
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
From the the given graph it is clear that graph A shifts 1 unit right to get the graph B. So, a=-1, b=0.
[tex]g(x)=\sqrt[3]{x-1}[/tex]
From the the given graph it is clear that graph A shifts 1 unit down to get the graph C. So, a=0, b=-1.
[tex]h(x)=\sqrt[3]{x}-1[/tex]
Therefore, the required functions are [tex]g(x)=\sqrt[3]{x-1}[/tex] and [tex]h(x)=\sqrt[3]{x}-1[/tex].
Determine the measure of obtuse angle A. answers: A) 130° B) 122° C) 58° D) 7°
Answer:
B) 122 degrees.
Step-by-step explanation:
Consider the kite :- the 2 angles at the tangents are 90 degrees so we have:
9x - 5 + 14x + 24 + 90 + 90 = 360
9x - 5 + 14x + 24 = 180
23x + 19 = 180
23x = 161
x = 7
So the obtuse angle = 14(7) + 24
= 98 + 24
= 122 degrees.

If y varies jointly with x and y =3 when x=2 and z=4 find y when x=8 and z=12
Answer:
y=10
Step-by-step explanation:
As you can see, the order when x=2 and z=4, is y=x+1, z=y+1, therefore y was 3.
Then, you can find y when x=8 and z=12 by:
12-8=4 (the difference between z and x)
and then divide 4 by 2 (the number of intervals between x, y, and z)
then get 2 (as the difference between x and y.
The answer is 8+2=10.
