Step-by-step explanation:

The required probability that they differ in length by more than 10 cm is 1.

Given that,
A hardware store sells planks of wood. the lengths, in centimeters, of the planks are normally distributed with a mean of 210 and a standard deviation of 7. two planks are selected at random. find the probability that they differ in length by more than 10 cm is to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,

The
P(x > 10) = p(z = (x - μ)/σ)
P(x > 10) = p(z = (10 - 210)/7)
P(x > 10) = p(z = -28.57143)
P(x > 10) = 1

Thus, the required probability that they differ in length by more than 10 cm is 1.

The value of Cos(4π/3) is (-1/2) i.e., negative one half.

The given function is Cosine (Start fraction 4 pi over 3 end fraction) and this can be written simply as,

Cos(4π/3)

On splitting 4π/3 in two parts, this can also be written as

= Cos(π + (π/3))

(π + (π/3)) lies in the third quadrant and in the third quadrant the value of cosine function is negative. So, using quadrant sign for cosine function, this can be written as

= -Cos(π/3)

Now, Substitute the value of Cos(π/3) = 1/2.

= (-1/2)

Cos(4π/3) = (-1/2)

The value of Cos(4π/3) is (-1/2) i.e., negative one half.

Answer:

[tex]\boxed{3} \;v^2 + \boxed{4}\;v + \boxed{5}[/tex]

Step-by-step explanation:

Original expression: 3 + v + 4v² + 2 - v² +3v

Combining like terms in a equation means grouping them together to get a single instance of that term instead of multiple

For example in this expression we can see there is a +4v² and a -v². Group these together and simplify algebraically to get a single v² expression. Do the same with the others.

3 + v + 4v² + 2 - v² +3v

Group the v² terms together to get 4v² - v² = 4v² - 1v² = 3v²  (v² == 1v²)
(since the variables are same we can simply add the coefficients

Now group the v terms and simplify

3 + v + 4v² + 2 - v² + 3v
v + 3v = 4v

Finally group the constants
3 + v + 4v² + 2 - v² +3v
3 + 2 = 5

So the final expression is

3v² + 4v + 5

The numbers are what you put in the boxes for each

Usually this process is done in a few steps
3 + v + 4v² + 2 - v² +3v

= (4v² - v²) + (v + 3v) + (3 +2)
= 3v² + 4v + 5

The values of x and y are x = 45/7 and y = 42/5

To calculate the value of x

Here, we make use of the ratio

AC : BC = AQ : QP

This gives

x : 5 = x + 9 : 12

Express as fractions

x/5 = x + 9/12

Cross multiply

12x = 5x + 45

Evaluate the like terms

7x = 45

Divide by 7

x = 45/7

To calculate the value of y

Here, we make use of the ratio

AB : BC = AP : PQ

This gives

6 : 5 = 6 + y : 12

Express as fractions

6/5 = 6 + y/12

Cross multiply

30 + 5y = 72

Evaluate the like terms

5y = 42

Divide by 5

y = 42/5

Hence, the values of x and y are x = 45/7 and y = 42/5

The graph that represents the inequality is graph b

From the question, we are to graph the given inequality

The given inequality is

y ≥ |x+5|-3

To graph the inequality, we will write the inequality as an equation and we will find some of the points on the line

When x = 0

y = |x+5|-3

y = |0+5|-3

y = |-3

When y = 0

y = |x+5|-3

0 = |x+5|-3

0 = (x + 5) - 3 and 0 = -(x + 5) -3

3 = x + 5

x = 3- 5

x = -2

and

0 = -(x + 5) -3

x + 5 = -3

x = -3 - 5

x = -8

The graphs that has the points above are graphs b and d.

Since the inequality sign is ≥ when y is the subject, the solution to the inequality is above the lines.

Hence, the graph of the inequality is graph b.

Answer:

See the picture below

Step-by-step explanation:

Your equations are in the slope-intercept form of a line.  The equations are make up of a slope and a y-intercept.

y = mx + b  The m is the slope (the steepness of the line) and b is the y-intercept.  This is where the line crosses the y axis.

I would start with the y intercept.  Look at the first equation

y = x -8  The -8 tells us that this graph crosses the y axis at (0,-8)  From that point, we will use the slope.  The slope is the number before the x.  If we do not see a number than it is 1.  We want to make this a fraction. What is 1 as a fraction?  1/1  This means that from -8 where the graph crosses the y axis we will follow the pattern of up one, one to the right.

Let's look at the second graph

y = -x + 5.  This tells us that we cross the y axis at (0,5).  Our slope is -1.  What is -1 as a fraction?  -1/1.  This means that we will move down 1 and right one.  We will follow that pattern.

Let's look at the third graph

y = 3/4x - 1  We cross the y axis at (0,-1)  From that point we move up 3 and right 4.

y = 3 means that no matter what x is, y will be -3.  This creates a horizontal line.

x = -4 means that not matter what y is, x will be -4.  This creates a vertical line.

2(I) We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.

8348 = 8350(rounded to 3 SF)

2(ii) 0.00796 = 0.0080

2(II) 6.329 = 6

2(III) 0.05684 = 0.0568

Step-by-step explanation:

1.i

2a^-1 × 3a²

remember, when we multiply factors with the same base value or variable, we keep that base value or variable and simply add the exponents.

-1 + 2 = 1

so, we get

2×3 × a¹ = 6a

1.ii

(1/2)^-3

remember, the "-" on the exponent just means 1/...

so, it is actually

1 / (1/2)³ = 1 / 1/8 = 8

1.iii

2a^-1 × (3a)²

similar to the first one, but remember, when we put the product of factors to a certain power, we need to do this for every factor of the inner multiplication :

2a^-1 × 9a² = 2×9 × a¹ = 18a

2.

the first significant figure is the first digit in the number reading from the left, that is not 0. it can be before or after the decimal point.

any digit (now continuing to read further to the right) after the first significant figure is again a significant figure even if it is 0.

i.

8.348 is rounded to 3 significant figures : 8.35

ii.

0.00796 is rounded to 2 significant figures :

0.0080 or 0.008 (because if the last digit after the decimal point is a 0, we can ignore it).

iii.

6.329 is rounded to 1 decimal place : 6.3

iv.

0.05684 is rounded to 3 decimal places : 0.057

3.

the sum of interior angles in a polygon is (n − 2) × 180°. where n is the number of sides.

as deca stands for 10, a decagon has 10 sides and 10 vertexes.

the sum of its inner angles is

(10 - 2) × 180° = 8 × 180° = 1440°

1170° of that is already covered by the first 7 angles.

so, we have left

1440 - 1170 = 270°

for the remaining 3 angles (that are all equal).

so,

270 = 3×angle

angle = 270/3 = 90°.

so, all of the 3 remaining angles are 90°.

5/6 - 1/9=?/? - ?/? = ?/? , value of each (?/?) is

Convert the given terms into like terms

Least common multiple of (6,9)=18

Value of each ( ?/?)
