Answer and Step-by-step explanation:
Solution:
Given:
µ = 50
∂ = 15
Lowest rating given to exemplary.
The top 10 %of the employees are related exemplary:
P(x > L) = 10 % =0.10
The average probability table in the appendix contains the only probability of the form.
P (0 < x< L ) = p ( x > 0 ) – P ( x > L )
= 0.5 -0.10
= 0.40
z- Score in the normal probability table in the appendix corresponding to a probability of 0.40 or the closest probability.
Z = 1.28
The standardized score is the value x decreased by the mean and then divided by the standard deviation.
Z = x - µ / σ
L = x = µ +z0
= 50 + 1.28(15)
= 69.2
Lowest rating giving to competent:
The lower boundary of competent is boundary of bottom 30%
P(x < L ) = 30% = 0.30
The normal probability table contains only probability of the form p( 0≤z≤z0)
P( 0< x < -L) = P(L < x < 0)
= p(x < 0) – p(x < L)
=0.5 – 0.30
= 0.20
Z score in normal probability corresponding to the probability of 0.20
-z = 0.52
Z= - 0.52
Value x decreased by the mean and divide by standard deviation:
Z = x - µ / ∂
L = x = µ + zo
= 50 – 0.52(15)
= 42.2

Sienna has a bag of 10 marbles. Five marbles are blue, four marbles are red, and 1 marble is yellow. Sienna draws two marbles from the bag without replacing the marble. What is the probability of drawing two blue marbles?
probability of drawing two blue marbles= 5/10
= 1/2
Given parameters:
Number of marbles in the bag = 10 marbles
Number of blue marbles = 5 marbles
Number of red marbles = 4 marbles
Number of yellow marbles = 1 marble
Unknown:
The probability of drawing two blue marbles.
Probability is the likelihood of an event to occur. It is the number of possible outcomes divided by the sample space.
Probability values ranges from 0 to 1
1 is a certainty that an event will occur.
0 shows that the event will not occur.
The probability of drawing the first blue marble = [tex]\frac{5}{10}[/tex]
Probability of drawing the second marble without replacing the marble = [tex]\frac{4}{9}[/tex]
Now,
The probability of drawing two blue marbles without replacement is;
= [tex]\frac{5}{10}[/tex] x [tex]\frac{4}{9}[/tex]
= [tex]\frac{2}{9}[/tex]
So the probability of picking two marbles without replacement is [tex]\frac{2}{9}[/tex]

Twice the sum of a number and nine is 24. Find the number.
Answer:
3
Step-by-step explanation:
2 (n + 9) = 24 this is the equation
to solve for n (number):
2(n+9)=24 // Distribute the 2 into parentheses
2n + 18 = 24 // Subtract 18 on both sides of equal sign
- 18 -18
2n = 6 // Divide by 2 on both sides of equal sign

Negative

Zero
d
Positive
Answer:
A, undefined
Step-by-step explanation:
The general rule is that vertical lines are undefined slope, because there's literally no change in x values. The vertical line test also fails, meaning there is no slope. Horizontal lines have a slope of 0, while vertical lines don't own any numbers that are important except for x-axis numbers.
If you do y2-y1 over x2-x1, you literally get 1/0 which is nothing. 0/1 = 0, but 1/0 is nothing.

x = 8, and y = 21
Step-by-step explanation:
You probably don't need this since this question was yesterday, but if you still need help:
I'm not the best at explaining but, Angles EOF and FOG are complementary, making 3y equal to 63. 63 divided by 3 is 21 making y = to 21. Angles AOE and GOB are also complementary adding them in the equation makes 9x + 18.
90 degrees minus 18 is 72, 72 divided by 9 is 8. Making 8 equal to x. 9x +18 ((9)8 + 18) is equal to 90 degrees.

Answer: x=6
Step-by-step explanation: in this equation you're trying to
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6-2*x-(6*x-10*x+18)=0
Pull out like factors :
-12 + 2x = 2 • (x - 6)
x-6 = 0
Add 6 to both sides of the equation :
x = 6

Step-by-step explanation:
A market researcher, having collected data on breakfast cereal expenditures by families with one, two, three, four, or five children living at home, plans to use an ordinary regression model to estimate the mean expenditures at each of these five family size levels. However, the researcher is undecided between fitting a linear or a quadratic regression model, and the data do not give clear evidence in favor of one model or the other. A colleague suggests: "For your purposes, you might simply use an ANOVA model." Is this a useful suggestion? Explain.
Answer:
Yes it is a useful suggestion
Step-by-step explanation:
Using the ANOVA model is a good idea because using it would give allowance For us to compare the five means of the five different family sizes. By this, during investigation there would be no confusion as to if a quadratic or linear relationship exists between the variables family size and breakfast cereal expenditure.
We would be comparing the mean expenditure of food of these 5 different family size levels so anova is useful.
Answer and Step-by-step explanation:
ANOVA model is mathematical model describe relationship between response and treatment.
One way ANOVA is given by:
YIJ = µ + Ti +Єij
Where, yij represent jth observation on ith treatment.
In this question, researcher collected data on the breakfast expenditure of a family whose size is five.
Yes, we can use ANOVA model. ANOVA can be used even if there is quadratic nonlinear relationship between expenditure and family size.
Since, the family size is five; we have to compare their mean expenditure on food.
The ANOVA one way model is:
YIJ = µ + Ti +Єij
For i=1, 2,3,4,5 and j= 1, 2,3,4,5
With hypothesis,
H01 : µ1 are equal.
H11 : at least two i not equal to j.

Suppose you walk 2 miles in 35 minutes. 4. write a proportion to find how far you would walk in an hour if you were to continue at the same rate.
Answer:
2/35 * x/60
Step-by-step explanation:
the x is what you're trying to find. the 60 is how many minutes there are in an hour. when setting up this proportion, you can't put 1 for 1 hour because you have 35 minutes. if it says minutes, then keep everything in minutes. from here, you would cross multiply and solve, that should give you the answer :) hope this helps <3

You have been waiting for months. The latest version of your favorite video game comes out today. You have mowed lawns, done extra chores, and saved up gift money. The new game costs $49.99. You have exactly $50.00 saved. So you are good to go, right? In 3 to 5 sentences explain if you have enough money to buy that game in Pennsylvania where sales tax is 6% If you have enough money, will you have change? If you do not have enough money, how much more do you need?
The savings are not enough to buy the video game due to sales tax and $ 2.99 is needed more to buy the latest version of favorite video game.
What is the formula to calculate sale tax ?The sales tax is calculated by multiplying the cost price by the rate of sales tax.
Amount of sales tax = rate of sales tax × Cost price
Rate of sales tax = percent of sales tax / 100
Savings money = $ 50.00
Cost price = $ 49.99
Given percentage of Sales Tax = 6%
Amount of sales tax = (sales tax/ 100 ) × $ 49.99
= (6/100)× 49.99
= 2.9994
Total Selling price of the video game will be = cost price + sales tax
= 49.99 + 2.9994
= $ 52.9894
= $ 52.99
Selling price is greater than savings it means more money is needed to buy the video game.
Extra money needed = Selling price - savings = $52.99 -$ 50.00= $ 2.99
Therefore, $ 2.99 is needed more to buy the latest version of favorite video game
