James' grades on his last five tests were 93, 95, 89, 95, and 100. What does he need to make on his last test to have a mean (average) of exactly 95?

Answers

Answer 1

Answer: 98

Step-by-step explanation:

First find the mean of the numbers you currently have.

93 + 95 + 89 + 95 + 100

and divide by 5 to get 94.4.

Now you need to find the extra number.

The number has to be higher than 94. I know there is an easier way, but I started by adding 100 and kept going down til I was at 98.

93 + 95 + 89 + 95 + 100 + 98

divided by 6 is 95

4x-2=-13 solve for x

Answers

Answer:

x = -11/4

Step-by-step explanation:

4x - 2 = -13

(add 2 on both sides)

4x - 2 + 2 = -13 + 2

4x = -11

(Divide 4 on both sides)

4/4x = -11/4

x = -11/4

Answer:

ANSWER :-

[tex]4x - 2 = -13\\4x = -13 + 2\\4x = -11\\x = - \frac{11}{4} \\x =- 2.75\\[/tex]

The value of x is  - 11/4 in fraction form & - 2.75 in standard form.

# RainbowSalt2222

Which of the following choices is the standard deviation of the sample shown
here?
18, 19, 20, 21, 22
A. 2
B. 12.5
C. 20
D. 2.5
E. square root of 2

Answers

Answer:  E. square root of 2

We can write that in shorthand as sqrt(2)

sqrt(2) = 1.41421 approximately

======================================================

Explanation:

Step 1)

Add up the values to get 18+19+20+21+22 = 100

Divide by n = 5, since there are 5 items in the list. So 100/n = 100/5 = 20

The sample mean is xbar = 20

--------------

Step 2)

Subtract the mean from each data value

18 - xbar = 18 - 20 = -219 - xbar = 19 - 20 = -120 - xbar = 20 - 20 = 021 - xbar = 21 - 20 = 122 - xbar = 22 - 20 = 2

The results we get are: -2, -1, 0, 1, 2

---------------

Step 3)

Square the results from the previous step

(-2)^2 = 4(-1)^2 = 1(0)^2 = 0(1)^2 = 1(2)^2 = 4

The results here are: 4, 1, 0, 1, 4

---------------

Step 4)

Add up those squares from the previous step: 4+1+0+1+4 = 10

Now divide by n = 5 to get 10/n = 10/5 = 2

The result 2 represents the population variance. Applying the square root to the population variance leads to the population standard deviation. So we end up with the final answer of sqrt(2). The answer is choice E.

sqrt(2) = 1.41421 approximately

---------------

Note: if you want the sample standard deviation, then you divide by n-1 = 5-1 = 4, but the other steps are the same as before.

PN = LO

__________________________

(LO)^2 = (LN)^2 + (NO)^2

(LO)^2 = 6^2 + 8^2

(LO)^2 = 36 + 84

(LO)^2 = 100

LO = √100

LO = 10

__________________________

Thus :

PN = 10

Step-by-step explanation:

So, we can assume that LN and PO are equal in length and NO and LP are equal in length as well.  LO and PN are also equal.

We can see that PN is the hypotenus of either triangle NLP or NOP.  LO is the hypotenuse of LOP and LON, so those could be used to find the length as well.  I rather work with NOP, but any work.

We know that NO is 8 units long and LN is 6 units long.  Because LN = PO, PO = 6 units.

So, using the pythagorean theorem, the hypotenuse is:

8^2 + 6^2 = c^2

64 + 32 =c^2

sqrt(96)=c

c~9.8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}=xy_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (8, 5)

m = [tex]\frac{5-8}{8-2}[/tex] = [tex]\frac{-3}{6}[/tex] = - [tex]\frac{1}{2}[/tex]

Hi there!

I believe your answer is:  

The second option, [tex]\boxed{x+41=90}[/tex].

»»————- ★ ————-««  

Here’s why:  

In the picture given, there are two angles that, together, make up a right angle. You can also tell that it is a right angle because of the box marked in the bottom left corner. The angles in the picture are also complementary angles. Complementary angles add up to 90°. Right angles measure 90°.

⸻⸻⸻⸻

We can use the information given to set up an equation.

[tex]\boxed{\text{An equation to find 'x'.}}\\\\\text{The sum of the angle's measurements: }90$^{\circ}$\\\\\text{The given measurement for one of the angles: }41$^{\circ}$\\\\----------------\\\\\underline{The sum of the two angle measurements would be 90 degress.}\\\\\text{Given angle mesurement} + x = 90\\\\\boxed{41 + x = 90}[/tex]

Option B matches the equation made. Therefore, option B should be the correct answer.

=x+2/x(x+1) - 3/x^2-2x+x-2

The terminal side of O is in quadrant Il and sin 5/13 = . What is cos 0?
A. 5/12
B.12/13
C.-5/12
D-12/13

Answers

If the terminal side of θ is in quadrant || and sin θ = 5/13, then the value of cos θ = -12/13.

Given that,

Terminal side of θ is in quadrant ||.

Sin θ = 5/13

We have the trigonometric identity,

sin² θ + cos² θ = 1

Substituting the value of Sin θ = 5/13, we get,

(5/13)² + cos² θ = 1

cos² θ = 1 - (5/13)²

          = 1 - 25/169

          = 144/169

cos θ = √ (144/169)

         = ± 12/13

We have the terminal side of θ is in second quadrant. In the second quadrant, all the trigonometric values except sin are negative.

So, cos θ = -12/13
