Answer:

a. The percentage of vehicles who pass through this construction zone who are exceeding the posted speed limit =90.82%

b. Percentage of vehicles travel through this construction zone with speeds between 50 mph and 55 mph= 2.28%

Step-by-step explanation:

We have to find

a) P(X>40)= 1- P(x=40)

Using the z statistic

Here

x= 40 mph

u= 44mph

σ= 3 mph

z=(40-44)/3=-1.33

From the  z-table   -1.67 = 0.9082

a) P(X>40)=

Probability exceeding the speed limit = 0.9082 = 90.82%

b) P(50<X<55)

Now

z1 = (50-44)/3 = 2

z2 = (55-44)/3= 3.67

Area for z>3.59 is almost equal to 1

From the z- table we get

P(55 < X < 60) = P((50-44)/3 < z < (55-44)/3)

     = P(2 < z < 3.67)

     = P(z<3.67) - P(z<2)

     = 1 - 0.9772

     = 0.0228

or 2.28%

Answer:

1/26 meter

Step-by-step explanation:

You would start by dividing 1/4 by 6. You'd have to multiply 1/4 by the reciprocal of 6 (the reciprocal of 6 would be 1/6). Then you get (1/4) * (1/6), which is equal to 1/24.

Carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.

Let the length of each piece = x meters

Since, the number of pieces (of equal length) of the wooden board = 6

Therefore, total length of wooden board = 6x

It's given in the question that the length of the wooden board is [tex]\frac{1}{4}[/tex] meter.

Therefore, 6x = [tex]\frac{1}{4}[/tex]

[tex]\frac{6x}{6}=\frac{1}{4\times 6}[/tex]

[tex]x=\frac{1}{24}[/tex] meter

    Hence, carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.

The value of n is 5 + 8/y for that expressions (3y + 1) + (2y + 8) and (ny + 9) are equivalent.

An algebraic expression is consists of variables, numbers with various mathematical operations.

The given expressions are (3y + 1) + (2y + 8) and (ny + 9)

Also, both the expressions are equivalent to each other.

To find the value of n, equate expressions  (3y + 1) + (2y + 8) and (ny + 9),

3y + 1 + 2y + 8 = n y + 1

5y + 9 = n y + 1

5y + 9 - 1 = n y

5y + 8 = n y

n = (5y + 8) / y

n = 5 + 8/y

The required value of n is 5 + 8/y.

Step-by-step explanation:

The number of small sized bowls on the counter = 68 bowls

The number of medium sized bowls on the counter = 82 bowls

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of small bowls on the counter be = x

Let the number of medium bowls on the counter be = y

The total number of bowls is = 150

So , the equation will be

x + y = 150   be equation (1)

The amount the small bowl can hold = 4 ounces

The amount the medium bowl can hold = 6 ounces

The total amount of all the bowls on the counter = 764 ounces

So , the equation will be

4x + 6y = 764   be equation (2)

Now , on simplifying the equation (1) and equation (2) , we get

Multiply equation (1) by 4 , we get

4x + 4y = 600   be equation (3)

Subtracting equation (3) from equation (2) , we get

2y = 164

Divide by 2 on both sides , we get

y = 82

Therefore the number of medium sized bowl is 82 bowls

Substituting the value of y in equation (1) , we get

x + y = 150

x + 82 = 150

Subtracting 82 on both sides , we get

x = 68

Therefore , the number of small sized bowl is 68 bowls

Hence ,

The number of small sized bowls on the counter = 68 bowls

The number of medium sized bowls on the counter = 82 bowls

Answer:

A

Step-by-step explanation:

Answer:

h(x) = x-5 . The domain of h(x) is (- infinity,3) U (3, infinity)

Step-by-step explanation: plato/edmentum

The domain of h(x) is  (-∞ , 3 ) ∪ (3,∞) .

The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function. When looking at a graph, the domain is all the values of the graph from left to right. The range is all the values of the graph from down to up.

According to the question

f(x) = [tex]x^{2}[/tex] − 8x + 15

g(x) = x − 3

h(x) = f(x) ÷ g(x)

i.e,

h(x) = [tex]\frac{ x^{2} -8x + 15}{x-3}[/tex]

now,

x ≠ 3

[tex]h(x) = \frac{(x-5)(x-3)}{(x-3)}[/tex]

so,

Domain or x ∈ (-∞ , 3 ) ∪ (3,∞)

Hence, The domain of h(x) is  (-∞ , 3 ) ∪ (3,∞)
