Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8x−

=x+12

8x+−3=x+12

8x−3=x+12

Step 2: Subtract x from both sides.

8x−3−x=x+12−x

7x−3=12

Step 3: Add 3 to both sides.

7x−3+3=12+3

7x=15

Step 4: Divide both sides by 7.

So since they are similar
AC/BC=CD/CE

so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units

How do I do this and what’s the answer

lakkis [162]

Answer:

The area of the four curved surfaces is the area of one circle with a radius of 4 cm

Area = PI * radius^2

Area = PI * 4 ^ 2

Area = PI * 16 = 50.26548245744 sq cm

Area of entire square = 8 * 8 = 64 sq cm

Area of yellow region = 64 - 50.265 sq cm =

= 13.735 = 13.7 sq cm (rounded to nearest tenth)

Answer:

Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.

A score of 74 is not within one standard deviation of the mean.

Step-by-step explanation:

Here the given details are,

Mean = 68

SD = 4

Distribution is normal.

Z-score for x = 74 is given as below:

$Z = (X - mean)/SD\\Z = (74 - 68)/4\\Z = 1.5$

So, the score of 74 is 1.5 standard deviations from the mean.

$Mean + 1\timesSD = 68 + 1\times4 = 72Mean - 1\timesSD = 68 - 1\times4 = 64$

Therefore the score is not lies between 64 and 72.

Yes, the upper level of one standard deviation is 72.
