what is 12x8 please tell me i need to know :) ")

Answers

Answer:

96

Step-by-step explanation:

10 x 8 = 80

2 x 8 = 16

so 80 + 16 = 96 :)

The equivalent value of the equation is A = 96

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be p = 12

Let the second number be q = 8

Now , A = pq

On simplifying the equation , we get

A = 12 x 8

So , the left hand side of the equation is equated to the right hand side by the value of 12 x 8

On multiplying 12 times 8 , we get

A = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8

A = 96

Therefore , the value of A = 96

Hence , the expression is A = 96

Compute and compare the values of the sample mean and median.
By how much could the largest sample observation be decreased without affecting the value of the median?

Answers

Answer:

[tex]Mean = 1.030[/tex]

[tex]Median = 1.009[/tex]

[tex]Difference = 0.141[/tex]

Step-by-step explanation:

Given

Data:

.736, .863,  .865,  .913

.915, .937, .983,  1.007

1.011, 1.064, 1.109, 1.132

1.140, 1.153, 1.253, 1.394

Solving (a): Mean and Median

Mean

Mean is calculated as thus;

Mean = Summation of observation divided by number of observations[tex]Mean = \frac{.736 +.863 +.865 +.913 +.915 +.937 +.983 +1.007 +1.011 +1.064 +1.109 +1.132 +1.140 +1.153 +1.253 +1.394}{16}[/tex]

[tex]Mean = \frac{16.475}{16}[/tex]

[tex]Mean = 1.0296875[/tex]

[tex]Mean = 1.030[/tex] Approximated

Median

Since the number of observation is 16;

[tex]Median = \frac{16 + 1}{2}[/tex]

[tex]Median = \frac{17}{2}[/tex]

Median = 8.5th item

This can be determined by calculating the average of the 8th and 9th item

[tex]Median = \frac{1}{2}(1.007 + 1.011)[/tex]

[tex]Median = \frac{1}{2}(2.018)[/tex]

[tex]Median = 1.009[/tex]

Solving b:

For the median to remain 1.009, the largest sample (1.394) must be greater than or equal to 1.253

Calculating the difference:

[tex]Difference = 1.394 - 1.253[/tex]

[tex]Difference = 0.141[/tex]

Hence, it can be reduced by 0.141

x=\frac{7-y}{2}x=

​2

​7−y

​​  

The equation solved for y is  y=7-2x.

The given equation is 2x+y=7.

We need to solve the given equation for y.

How to solve an equation?

Solving equations is computing the value of the unknown variable still balancing the equation on both sides. An equation is a condition on a variable such that two expressions in the variable have equal value. The value of the variable for which the equation is satisfied is said to be the solution of the equation. An equation remains the same if the LHS and the RHS are interchanged.

Now, solving the equation for y, we get y=7-2x.

Put x=1, 2, 3, 4,....in the equation and find the y value.

So, put x=1 in equation  y=7-2(1)=5.

Put x=2, we get

y=7-2(2)=3

Verification: Put the ordered pair (1, 5) in the equation and verify.

That is, 5=7-2(1)

⇒5=5

Therefore, the equation solved for y is  y=7-2x.

.If m∠ ROT = 155, what are m ∠ ROS and m∠TOS?

Can someone explain how to do it also?

Answers

Answer:

ROS=72° TOS=83°

Step-by-step explanation:

(4x-20)+(3x+14)=155

7x-6=155

7x=161

x=23

4(23)-20=72

3(23)+14=83

Answer:

ROS is 72 degrees.

TOS is 83 degrees.

Step-by-step explanation:

So we know that the measure of Angle ROT is 155.

Angle ROT is the combined value of Angle ROS and Angle TOS. In other words:

[tex]ROT=ROS+TOS[/tex]

Substitute 155 for ROT, (4x-20) for ROS, and (3x+14) for TOS. Thus:

[tex]155=(4x-20)+(3x+14)[/tex]

Combine like terms:

[tex]155=(4x+3x)+(-20+14)[/tex]

Add:

[tex]155=7x-6[/tex]

Add 6 to both sides:

[tex]161=7x[/tex]

Divide both sides by 7:

[tex]x=23[/tex]

So, the value of x is 23.

Now, plug that into each of the Angle equations to solve for each angle:

[tex]ROS=4x-20\\ROS=4(23)-20[/tex]

Multiply:

[tex]ROS=92-20[/tex]

Subtract:

[tex]ROS=72[/tex]

Same thing for TOS:

[tex]TOS=3x+14\\TOS=3(23)+14[/tex]

Multiply:

[tex]TOS=69+14[/tex]

Add:

[tex]TOS=83[/tex]

And we're done!

Answers

Answer:

0.971%

Step-by-step explanation:

A percentage is simply a ratio to a whole.  If we assume 206 tons to be the whole, we can say this:

2 tons / 206 tons  == 0.00971

And the percentage is out of 100 so:

0.00971 * 100  == 0.971 %

Hence, 2 tons is 0.971% of 206 tons.
