In an effort to determine the most effective way to teach safety principles to a group of employees, four different methods were tried. Some employees were given programmed instruction booklets and worked through the course at their own pace. Other employees attended lectures. A third group watched a television presentation, and a fourth group we divided into small discussion groups. A high of 10 was possible. A sample of 5 tests were selected from each group. The results were: Sample Programmed Instruction Lecture TV Group Discussion 1 6 8 7 8 2 7 5 9 5 3 6 8 6 6 4 5 6 8 6 5 6 8 5 5 At the 0.01 level, what is the critical value
Answer:
critical value = 5.29
Step-by-step explanation:
Given that they are divided into 4 groups and a sample of 5 test was selected
N = 5 * 4 = 20
k = 4
∝ = 0.01
Df for numerator ( SS group )= k - 1 = 3
Df for denominator ( SSE group ) = N - k = 20 - 4 = 16
DF ( degree of freedom )
Next we will use the F table to determine the critical value
Critical value = [tex]F_{16,3,0.01}[/tex] = 5.29

What is the area of the figure show
• below?
-30 ft-
15 ft
- f
1551
A 315 f12
B 225 fra
C 180 ft2
D 90 fre?
Answer:
315 ft²
Step-by-step explanation:
•Split the shape into a triangle and a square.
•A=bh so 15*15=225 (area of square)
•Since the height of the square is 15, subtract given height of 3 from 15 which is 12 and that is the base of triangle.
• To find the height, subtract 15 since the base is equal to the top side.
•A=1/2bh for triangles so 1/2(15)(12) is 90.
•Add 225 and 90 then boom. 315ft²
What is the probability of rolling a number greater than or equal to 8 with the
sum of two dice, given that at least one of the dice must show a 6?
======================================================
Explanation:
I'll represent the dice results as an ordered pair. Something like (6,2) means the first die is a 6 and the second is a 2. The sum being 6+2 = 8.
There are only two ways to get to a sum of 8, and those two ways are:
(6,2)(2,6)Here are other possibilities if we allow the sum to be larger than 8
(6,3)(6,4)(6,5)(6,6)(3,6)(4,6)(5,6)(6,6)You should find that there are a total of 10 ways to have two dice add to a value that is 8 or larger, given that at least one of the dice must be a 6.
This is out of 6*6 = 36 ways to roll two dice without such a restriction. The probability we're after is 10/36 = (2*5)/(2*18) = 5/18
Side note: 5/18 = 0.2778 = 27.78% approximately
In a certain village of Nepal, all the people speak either Nepali, or Maithili
, or
both the languages. If 60% of them speak Nepali and 80% of them speak
Maithali, how many of them (%) speak both the languages?
Given,
Nepali speaker : 80% (Y)
Maithili speaker : 60% (X)
We know that,
Both language speaker = Y -X
Now,
Y- X
= 80- 60
= 20
Therefore, 20% people speak both languages
What is the solution to this inequality?
2(x-4) + 14 < x-1
O A. 1
O B. x>-7
C. -3 < x < 1
The solution of the inequality 2(x - 4) + 14 < x - 1 is:
x < -7
How to solve the inequality?Here we have the following inequality:
2(x - 4) + 14 < x - 1
To solve it, we need to isolate the variable in one of the sides, so let's do that.
Expanding the right side we will get:
2x - 8 + 14 < x - 1
2x + 6 < x - 1
Now group like terms:
2x - x < - 1 -6
x < -7
That is the solution.

The volume of the polyhedron is ______ cm3.
Answer:
Volume = 144 cm³
Step-by-step explanation:
Volume of the polyhedron = volume of triangular prism = ½*b*h*l
Where,
b = 4 cm
h = 6 cm
l = 12 cm
Substitute
Volume = ½*4*6*12
Volume = 144 cm³
How do I simplify this radical?
Answer:
Step 1: Find the prime factorization of the number inside the radical. Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind. Step 3: Move each group of numbers or variables from inside the radical to outside the radical.
Jeremy will roll a number cube, numbered 1–6, twice. What is the probability of rolling an odd number, then a number bigger than 2?

Find all complex solutions of the equation z⁴-1-i=0.
Answer:
Step-by-step explanation:
hello :
z⁴=1+i given : z² = t t is the complex number so : z⁴= (z²)² =t²
solve for t this equation : t² = 1+i
if : t = x+iy t² =(x+iy)² = x²+2xiy+(iy)² =x²-y²+2xyi ...... ( i² = -1)
t² = 1+i means : x²-y²+2xyi = 1+i
you have this system : x²-y² = 1.....(*)
2xy = 1.....(**)
slve for x and y you ca add this equation : ....(***)
( use : t² = 1+i
/t²/ = /1+i/ so :/t/² = /1+i/ .... (√(x²+y²))²=√(1²+1²) =√2 means x²+y² = √2)
the system is : x²-y² = 1.....(*)
2xy = 1.....(**)
x²+y² = √2 ....(***)
add (*) and (***) : 2x²= 1+√2
x² = (√2+1)/2
substrac (*) and (***) you have : y² = (√2-1)/2
use (**) the proudect xy is positif (same sign) so :
x=√( (√2+1)/2) and y = √( (√2-1)/2) so : t1 =√( (√2+1)/2)+i√( (√2-1)/2)
x= -√( (√2+1)/2) and y = -√( (√2-1)/2) so :t2= -t1
same method for equation : z² =t1 ..(2 solution ) and z² = t2..(2 solution )

Question 4 options:
A)
8
B)
–8
C)
9
D)
–9
Answer:
x = -9
Step-by-step explanation:
Given:
BC = x + 19
ST = x + 29
Required:
Value of x
Solution:
Midsegment theorem states that the midsegment of a triangle = ½ of the length of its third side
Thus:
BC = ½(ST)
Substitute
x + 19 = ½(x + 29)
Multiply both sides by 2
2(x + 19) = x + 29
2x + 38 = x + 29
Collect like terms
2x - x = -38 + 29
x = -9
THE TOPIC IS: AREA OF CIRCLES!! PLEASE HELP ME WITH THIS QUESTION!!! WHATS THE ANSWER?? I WILL GIVE YOU BRAINLIEST AND A THANKS!!! AND PLS PUT AN EXPLANATION!! THANK YOU GUYS SO MUCHHHH!! CAN YOU PLEASE DO BOTH OF THESE!!!
Step-by-step explanation:
8) Area of circle =
[tex]\pi {r}^{2} [/tex]
Radius = 1/2 of diameter (Diameter = 2x radius)
Radius = 1/2 × 10 in = 5 in.
Area of circle =
[tex]\pi {5}^{2} = 25\pi {in}^{2} [/tex]
11) Radius = 1/2 × 6m = 3m
Area of Circle =
[tex]\pi {3}^{2} = 9\pi {m}^{2} [/tex]
Note that I will leave both answers in terms of pi as I am not sure how you want to leave your answer as.
Answer:
area = πr×r
r = d/2
area = π (d/2)×(d/2)
so for problem 8,
area = pi×5×5 = 25π = 78.539 inches squared
