The mean of 100 observation is found to be 40. If at the time of compution two items were wrongly taken as 30 and 27 instead of 3 and 72. Find the correct mean

Answer:

Because a 2 or a 4 was rolled 3 out of 12 times in the experiment, t so the fraction would be 3/12 (or 3 over 12).

Simplified: 1/4 (or 1 over 4)

x=363.1

x=363.1

Answer:

Your answer is x=363.1

Step-by-step explanation:

To solve this we have to get X alone.

We do this by doing the inverse of everything on the same side as the X.

So for x-6.8 we add 6.8 to BOTH sides of the equation. To get x=363.1

Answer:

12cm

Step-by-step explanation:

bc= 13cm (c) hypotenuse is always c

dc= 10÷2. (b)/(a) it can be a or b, any also long it's not the hypotenuse

= 5cm

bd= use phytagoras theorem formula

c²=a²+b²

13²=5²+b²

169=25+b²

169-25=b²

144=b²

b=

[tex] \sqrt{144} [/tex]

b=12

bd=12cm

Answer:

126 degrees

Step-by-step explanation:

The opposite angles of a parallelogram are equal, so 4x + 2 = 8x - 50. By subtracting 4x from both sides of this equation, we get that 2 = 4x - 50. Adding 50 to both sides yields 52 = 4x, and dividing by 4 gives us that x = 13.

By substituting this, we see that the measure of angle A is 4(13)+2, which is 54 degrees. Angle B is supplementary to angle A, so its measure is 180-54, which is 126 degrees.

Step-by-step explanation:

To find - Enter five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value of -3/4 (the fraction)

Solution -

Expression for sum is -

1/4 + (-1) = -3/4

Expression for difference is -

(1/4 - 1) = -3/4

Expression for product is -

(-3/2)(1/2) = -3/4

Expression for quotient is -

(1 - 4)/4 = -3/4

Expression that involves at least two operations is -

-(1/4 + 2/4) = -3/4

Answer:

15

Step-by-step explanation:

Keep, Change, Flip. That is the mantra you should have when you come to division problems with fractions. So you would keep the 5, change the sign into multiplication, and flip the fraction from 1/3 to 3/1 (which actually is just 3). Then you would multiply 5 * 3. Your answer should be 15.

Answer:

15

Step-by-step explanation:

To divide any number by a fraction, flip the fraction and then multiply:

[tex]5 \div \frac{1}{3} = 5 \cdot \frac{3}{1} = 15[/tex]

Answer:

The mean of A and C is equal to 10.

Step-by-step explanation:

We know that,

[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Total no of obervations}}[/tex]

The mean of A and B is 20,

[tex]A+B=20\\\\A+B=40\ \ .........(1)[/tex]

The mean of B and C is 24,

[tex]B+C=24\times 2\\\\B+C=48\ \ .........(2)[/tex]

The mean of A,B and C is 18,

[tex]A+B+C=18\times 3\\\\A+B+C=54\ .....(3)[/tex]

Put the value of A+B from (1) in (3),

C = 14

Put the value of B+C from (2) in (3)

A = 6

Mean of A and C is :

[tex]M=\dfrac{A+C}{2}\\\\M=\dfrac{14+6}{2}\\\\M=10[/tex]

So, the mean of A and C is equal to 10.

Answer:

y=-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-(-3))/(3-(-4))

m=(-3+3)/(3+4)

m=0/7

m=0

y-y1=m(x-x1)

y-(-3)=0(x-(-4))

y+3=0(x+4)

y+3=0

y=0-3

y=-3

Answer: 36.25°

Step-by-step explanation:

Use SOHCAHTOA (sin, cosine and tangent)

SOHCAHTOA:

SOH: Sin(θ) = Opposite / Hypotenuse

CAH: Cos(θ) = Adjacent / Hypotenuse

TOA: Tan(θ) = Opposite / Adjacent

When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.

And just as a note, θ this symbol is called theta, and it represents an angle.

TAN(θ) = Opposite / Adjacent = 11/15

Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.

TAN(θ) = [tex]\frac{11}{15}[/tex]

θ = [tex]tan^-1(\frac{11}{15} )[/tex]

Then, using a calculator, solve. The answer is about 36.25°
