What is 9.66 rounded to the nearest tenth

2 answers:

6 0

9.66
^ This is the tenths place.

Look at the number after it, if it's 5 or more we round up, if it's 4 or less we round down.

The number is 6, so we round up to 9.7.

9.7, because .66, the 6 in the 100 place rounds to 7, because five and higher round up and 4 and lower round down, another example of this is 23, which rounds down to 20, and 47 rounds up to 50

Substitution for {2x-3y=11 and -x + 2y = -6

Svetradugi [14.3K]

Step-by-step explanation:

-x+2y=-6

x-2y=6

x=2y+6

substitute in 2x-3y=11 gives us 2(2y+6)-3y=11

4y+12-3y=11

y=-1

-x+2(-1)=-6

-x=-4

x=4

Please help with this math problem for trig. A 6 m ladder is leaning against a wall. The base of the ladder is 1.5 m from the wa

VladimirAG [237]

Answer:

a = 5.81 m

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

where b= 1.5 and c= 6

a^2 +1.5^2 = 6^2

a^2 +2.25 = 36

Subtract 2.25 from each side

a^2 +2.25-2.25 = 36-2.25

a^2 = 33.75

Take the square root of each side

sqrt(a^2) = sqrt(33.75)

a = 5.809475019

We only take the positive root because length must be positive

n studying the sampling distribution of the mean, you were asked to list all the different possible samples from a small populat

Mashutka [201]

The Total outcome with replacement will be given by ,3² = 9, the mean of the samples will be 2 , 4.5 , 3 , 7 , 4

Mean predicts the central tendency of a data set , It is determined by the ratio of sum of all the numbers to the total numbers in the data set.

On the basis of given data

The number given is 2,4,7

Size of the sample = 2 with replacement

The Total outcome with replacement will be given by

3² = 9

Possible outcome can be

2,2 2,4 2,7 4,4 4,2 4,7 7,7 7,2 7,4

The sample mean can be calculated as

(a+b)/2

(2+2)/2 = 2

similarly the mean of the samples will be 2 , 4.5 , 3 , 7 , 4
