Plz help fast, correct, and answer every question asked!!!! (I will report if answer is stupid!!!)

Answer:

0.090401

Step-by-step explanation:

Given that:

Probability of graduate = 81% = 0.81

P( not graduate) = p = (1 - 0.81) = 0.19

1 - p = 0.81

Using binomial distribution :

P(x = x) = nCx * p^x * 1-p^(n-x)

n = 15 ; x =5

P(x = 5) = 15C5 * 0.19^5 * 0.81^(15 - 5)

P(x = 5) = 15C5 * 0.19^5 * 0.81^10

P(x = 5) = 3003 * 0.0002476099 * 0.12157665459056928801

P(x = 5) = 0.090401

Answer:

D:   (15/5) (0.19)^5 (0.81)^10

Answer: Q, it's the only horizontal line

Answer:

If 30% of 599.99 is 197.99 and 30% of 899.99 is 269.99 then you subtract 269.99-197.99= $72

Answer:

D. Reflection across x-axis

Step-by-step explanation:

When plotting the two points & then connecting the dots, it will not touch y-axis at all - it will be straight line and cross x axis

Answer:

The answer is D

Step-by-step explanation:

Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary

This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.

You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other

Hope this helped you!!!

Answer:

How do you find the zeros of a polynomial graphically?

Step-by-step explanation:

If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. The zeros of a polynomial can be found by finding where the graph of the polynomial crosses or touches the x-axis.

Answer:

The answer is (2+7)*2

Step-by-step explanation:

as you can see the you have to add the bottom to the top then multiply the answer by the height to what i did was i seen if there was anything that can add to 7 with the number 2 and 5 was so put 5 at the top and multiply 7 times two you get 14

Answer:

-7°

Step-by-step explanation:

every hour the temperature dropped 3° so in 6 hours it would be -7° because 3x6 is 18 and 11-18 is -7

Answer:

a) 6.1 feet

b) 12.6 feet

Step-by-step explanation:

Using trigonometric ratios we know that:

[tex]sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}[/tex]

AKA SohCahToa.

To find the height, we will use sine.

[tex]sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14[/tex]

To find the length we will use cosine.

[tex]cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6[/tex]

Answer:

It takes Sanjay 40 minutes and Zion 120 minutes

Step-by-step explanation:

If it takes Sanjay x minutes, it takes Sanjay 3 * x = 3x minutes

Painting together, they spent 30 minutes

1/x + 1/3x = 1/30

4/3x = 1/30

4 * 30 = 3x * 1

120 = 3x

x = 120/3

x = 40 minutes

3x = 3 * 40 = 120 minutes

Answer:

Step-by-step explanation:

If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...

  3x +2y = 520

  2x -y = 20

__

These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:

  (3x +2y) +2(2x -y) = (520) +2(20)

  7x = 560 . . . . simplify

  x = 80 . . . . . . divide by 7

  y = 2x -20 = 2(80) -20 = 140

The cost of a lamp is $80; the cost of an end table is $140.
