The mean of the scores is 90 what is the sum of the scores

Mathematics
1 answer:
Alik [6]3 years ago
4 0

Answer:

x*90= your answer.

Step-by-step explanation:

X being however many test scores there are.

If you have 4 test scores, you would multiply 4*90=360

If you had 3 test scores, you would do it again, 3*90=270.

And so on. Because the test scores number wasn't listed, I provided some answers on how to solve it.

For which rational expression is –2 an excluded value of x?
Kipish [7]

Answer:

option a is the answer

Step-by-step explanation:

put the value of x in each expression as x = -2

you'll see that in option a the expression becomes

\frac{x - 3}{ {x}^{2}  - 4}   =   \frac{ - 2 - 3}{ {( - 2)}^{2}  - 4}  \\  =  \frac{ - 5}{4 - 4} \\  =   \frac{ - 5}{0}

which is not defined. hence -2 is excluded value

20 less than12 times a number is 64, what is the number
Genrish500 [490]

20  <  12  ⋅  <em>x</em>  =  64

This is somewhat of a false equation though, due to  the left side  "20"  is not less than the right side  "12 ", which means that the given statement is false.

So I switched it up and made the variable "12"

<u>12  <  20  ⋅  </u><u><em>x</em></u><u>  =  64 </u>

12x - 20 = 64

12x = 64 + 20

12x = 84

12x⁄12 = 84⁄12  

x = 7

I hope this helps, as always. I wish you the best of luck and have a nice day, friend..

HELP NEEDED PLEASE!!!

Using vector concepts, it is found that:

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

<h3>How can a vector be represented in component notation?</h3>

Given a magnitude M and angle \theta, then a vector V can be represented as follows in component notation:

V = (M\cos{\theta}, M\sin{\theta})

In this problem, the magnitude and the angle are given, respectively, by:

M = 12, \theta = 143^\circ

Hence:

V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).

Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

Answer:

See below

Step-by-step explanation:

<u>Statement                                      | Reason                                             </u>

1. m∠A + m∠B + m∠C = 180°         | 1.  Angles in a triangle sum to 180°

2. 28° + x - 4° + 2x = 180°              | 2. Substitution

3. x=(180° - 24°)/3= 156°/3°= 52°   | 3. Algebra
