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%

Answers

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%

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?

Answers

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

QUESTION 1: True or false:

Do vertical angles prove parallel lines?

QUESTION 2:

Solve for x in the diagram below. PIC ATTACHED

Answers

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.

Answers

Answer:

F=10

Step-by-step explanation:

Add 13.5 and 14 to get 27.5.

2.25f+5=27.5

Subtract 5 from both sides.

2.25f=27.5−5

Subtract 5 from 27.5 to get 22.5.

2.25f=22.5

Divide both sides by 2.25.

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.

Answers

Answer

Step-by-step explanation:

The answer would be y=-x-3. 3x+3y=-9 is in standard form and you want it to be in y=mx=b form (slope-int) so subtract 3x by both sides. Now, you have 3y=-3x-9. Divide 3 to both sides, now you will get y=-x-3.

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

Answers

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
