let the number be X

6x-19.85=29.77

6x=29.77+19.85

6x=49.62

x=8.27

Hope that helps :)

Solution

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given data

$\begin{gathered} 165,46,20,88,180,45,85,165,8,8,23,26,67,168,136,21,143,8,84,22,106,131,16,152,171,64,33,116,151,117,99,61,159 \\ 73,51,136 \end{gathered}$

STEP 2: Find the mean

$\begin{gathered} mean=\frac{sum\text{ of data values}}{number\text{ of data values}} \\ sum\text{ of data values}=3144 \\ Number\text{ of data values}=36 \\ mean=\frac{3144}{36}=87.33333333\approx87.33 \end{gathered}$

mean is 87.33

STEP 3: Find the median

Make s the subject, v squared = u squared + 2as

tatiyna

v² = u²+2as

2as = v²-u²

s = (v²-u²)/2a

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

$y = mx + b$

where m=3 is the slope .

We substitute the slope to get:

$y = 3x + b$

We substitute the point to find b.

$- 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4$

The equation of the straight line is:

$y = 3x + 4$

6.Find the value of x. Don't forget your reasons.<br> (x-38)

anzhelika [568]

Answer:

x = 109

Step-by-step explanation:

The figure has one pair of parallel sides and is a trapezoid.

The lower base angle is supplementary to the upper base angle on the same side, thus

x + x - 38 = 180 , that is

2x - 38 = 180 ( add 38 to both sides )

2x = 218 ( divide both sides by 2 )

x = 109

If you roll a normal dice 120 times .how many 4s would you except to get

shusha [124]

Roll the dice 120 times

Number of outcomes from rolling the dice = 6
Probability of 4 falling in 1 roll = 1/6

Probability of the number of 4s in 120 rolls = 120 * 1/6
= 20 times

The probability that 4s falls in 120 dice rolls is 20 times.
