In a normal distribution, what is the probability that a data value will fall above the
data value associated with a z-score of 0.15?
A 55.96%
B 53.98%
C 44.04%
D 46.02%
Answer: C 44.04%
Step-by-step explanation:
in a normal distribution,
P(Z>z)= 1-P(Z<z) (*)
Here , we need to find : P(Z>0.15)
By using (*) , P(Z>0.15)=1- P(Z<0.15)
= 1- 0.5596 [By p-value table]
= 0.4404
= 44.04% [multiply 100 to convert into percent]
∴ the probability that a data value will fall above the data value associated with a z-score of 0.15 = 44.0%
hence, correct option : C 44.04%

QUESTION 1: True or false:
Do vertical angles prove parallel lines?
QUESTION 2:
Solve for x in the diagram below. PIC ATTACHED
Answer:
1.Yes, vertical angles prove lines parallel if there is a transversal and the corresponding vertical angles are congruent
2. x= 12
Answer:
1. In order to use Theorem 10.7, you need to show that corresponding angles are congruent. You can use the fact that ∠1 and ∠2 are vertical angles, so they are congruent. Because ∠2 and ∠3 are corresponding angles, if you can show that they are congruent, then you will be able to conclude that your lines are parallel.
2x - 1y = -9
y = - 5 - 5x
Answer:
x = - 7 and y = 30
Step-by-step explanation:
2x - y = -9
subtract 2x from either side
-y = -9 - 2x
divide either side by -1
y = 9 + 2x
Plug in 9 + 2x for y
9 + 2x = -5 - 5x
Add 5 to either side and subtract 2x from either side
14 = -2x
divide either side by -2
-7 = x
plug in -7 for x in one of the equations
y = -5 - ( 5 x -7 )
y = -5 - ( - 35)
y = -5 + 35
y = 30
plug in x and y
30 = -5 - ( 5 x -7)
30 = -5 - (-35)
30 = -5 + 35
30 = 30
Answer:
B. −19
Step-by-step explanation:
Multiply both sides of the equation by y , and then isolate the variable.

−1
=
9y
−19
=
y
Divide both sides by 9

Tamara earns her living as a salary plus commission employee. Her annual salary is $48,000, and she earns 4% commission on all sales she makes. If Tamara wants to make a total of $6,000 this month, how much in sales does she need to have? a. $30,000 b. $50,000 c. $100,000 d. $150,000 Please select the best answer from the choices provided
Answer:
b. $50,000
Step-by-step explanation:
The computation of the sales amount need to have is shown below:
But before that monthly income is
= Annual salary ÷ Number of months
= $48000 ÷ 12
= $4,000
Now the equation could be made which is shown below:
0.04x = $6,000 - $4000
0.04x = $2,000
X = $2000 ÷ 0.04
X = $50,000
Hence, the correct option is b. $50,000

how does cheese spoil?
Answer:
Microbiological spoilage of cheese is one of the important reasons that render the nutritious and tasty cheese not only inedible but also a potential source of infection. The spoilage may be due to bacteria or fungi. The defect due to contamination may arise from the surface of the cheese showing visual and organoleptic changes or it may be hidden internally.
Answer:
Cheese: It smells like sour milk.
If you spot mold on hard cheese, it's generally safe to cut off the moldy part and eat the rest, since the spores likely will not have spread throughout the cheese. Another sign that cheese has gone bad is a smell or taste of spoiled, sour milk.

Luka made an elaborate code to remember the 10 digit combination to his bicycle lock. This is the code he came up with:
F-G-E-D-A-K-B-J-C-H
Each letter stands for a different digit (0-9). Stusy the clues below to figure out what digit is represented by each letter. When two letters are written together without an operation symbol, they represent a tens digit and a ones digit.
F+F+F=D B÷H=K. H+A=CC. H+H=B. F•H=CK. D•F=KG. G+B+E=D+A+C A•H=KE J÷F=K. F/J=H/B

Sorry if this is too big just one on answer would help.
Answer:
The rate of change or the slope is 4/1 or just 4.
Step-by-step explanation:
To find the rate of change, you have to figure out the distance between the y values and x values.
The distance from 6 to 10 for number 1 is 4, and it continues with the same pattern of 4!
The distance in the x values for number one is just 1! It stays as one for the entire table.
Now we put our information in a fraction.
Y is always over X. Y/X
4/1 or just 4.
Lastly, I'm a bit confused on what exactly it means by Start value but I'm sure you can email your teacher about that.
Hope this helps! :)

Your school band needs to buy new recording equipment. The equipment will cost $3000. The band has collected $1200 in previous fundraisers. If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds?
Answer:
360
Step-by-step explanation:
Total amount needed = $3000
Amount available = $1200
Remaining amount = Total amount needed - Amount available
= $3000 - $1200
= $1800
If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds
Number of sandwiches to sell = Amount remaining / price of sandwiches
= $1800 / $5
= 360
Therefore, the band will need to sell 360 sandwiches to raise remaining funds
