Answer:

The probability there will be between 280 and 360 column inches of classified advertisement

P(280≤X≤360) = P(-2≤Z≤2) = 0.9544

Step-by-step explanation:

Step(i):-

Given that the mean  the population = 320

The standard deviation of the Population = 20

Let 'X' be the random variable in a normal distribution

Let 'X' = 280

[tex]Z = \frac{x-mean}{S.D} = \frac{280-320}{20} = -2[/tex]

Let 'X' = 360

[tex]Z = \frac{x-mean}{S.D} = \frac{360-320}{20} = 2[/tex]

Step(iii):-

The probability there will be between 280 and 360 column inches of classified advertisement

P(280≤X≤360) = P(-2≤Z≤2)

                        = P(z≤2) -P(z≤-2)

                       = P(z≤2)+P(z≤2)

                      = 2P(z≤2)

                     = 2×0.4772     ( from normal table)

                    = 0.9544

Answer:

(-1, 1)

Step-by-step explanation:

Midpoint formula: (x₁ + x₂/2 , y₁ + y₂/2)

Substitute the values into the formula.

(-5 + 3/2 , 3 - 1/2)

(-2/2 , 2/2)

(-1,1)

Therefore, the midpoint is (-1, 1).

Answer:

-3, -2 and -1

Step-by-step explanation:

Given the inequality -3(1-z)<9

Expand

-3(1)-3z <9

-3-3z <9

Add 3 to both sides

-3-3z+3<9+3

-3z<12

Divide both sides by -3

-3z/-3 >12/-3

z > -4

The required solutions are values greater than -4 and they are -3, -2 and -1

Answer:

Step-by-step explanation:

Answer:

a_n=224(1/2)^n-1

Step-by-step explanation:

In this geometric sequence, we can see that the common ratio is 1/2 and the 1st term is 224. using this information, we can plug it into the geometric series formula and we get a_n=224(1/2)^n-1.

Answer:

26 ounces per can

Step-by-step explanation:

28 is the unit rate of 56 ounces for every 2 cans

A division is a process of splitting a specific amount into equal parts.

A unit rate means a rate for one of something.

We need to find the unit rate  of 56 ounces for every 2 cans

To do this we need to divide Fifty six ounces with two.

56/2

Fifty six divided by two.

We get Twenty eight.

Hence 28 is the unit rate of 56 ounces for every 2 cans

Step-by-step explanation:

Answer:

[tex]P(Green\ candy\ or\ Blue\ candy) = 0.16[/tex]

Yes, they are mutually exclusive

Step-by-step explanation:

Given

Refer to the table in the question

Solving (a): P(green candy or blue candy)

This is calculated as:

[tex]P(Green\ candy\ or\ Blue\ candy) = P(Green) + P(Blue)[/tex]

From the question:

[tex]P(Blue) = 10\%[/tex]

[tex]P(Green) = 6\%[/tex]

So:

[tex]P(Green\ candy\ or\ Blue\ candy) = P(Green) + P(Blue)[/tex]

[tex]P(Green\ candy\ or\ Blue\ candy) = 6\% + 10\%[/tex]

[tex]P(Green\ candy\ or\ Blue\ candy) = 16\%[/tex]

Convert to decimal

[tex]P(Green\ candy\ or\ Blue\ candy) = 0.16[/tex]

Solving (b): Are they mutually exclusive?

Multiple events A and B are mutually exclusive if;

[tex]P(A\ or\ B) = P(A) + P(B)[/tex]

In (a) above:

[tex]P(Green\ candy\ or\ Blue\ candy) = P(Green) + P(Blue)[/tex]

and this is so every other possible colour of candy

e.g.

[tex]P(Red\ or\ Yellow) = P(Red) + P(Yellow)[/tex]

Hence:

The events are mutually exclusive

Answer:

Step-by-step explanation:

9.50 ÷ 1 = 9.50

18 ÷ 2 = 9.50

28.50 ÷ 3  = 9.50

38 ÷ 4 = 9.50

47.50 ÷ 5 = 9.50

Direct variation is the relationship between tow variables in which one is a constant multiple of other.

Here, If we take hours worked as 'x' and pay as 'y',

y = 9.50*x

Answer:

250 ft.

Step-by-step explanation:

It seems that you are learning the side-splitter theorem right now. If a line is parallel to one side of the triangle and intersects the other two sides, it divides the side proportionally. From the picture we can tell that the streets are parallel, with a line of intersection. Therefore, we can create the following equation of proportionality:

[tex]\frac{375}{300} = \frac{x}{200}[/tex]

Now that we have this equation, we can use the butterfly method to solve for x. We cross multiply:

[tex]375*200=300x\\[/tex]

Now, all we have to do is isolate the variable to find x:

[tex]75000=300x\\x=250[/tex]

Therefore, the distance of Orange Ave between the 3rd St. and 4th St. is 250 ft.

Answer:

Area of semicircle = 226.08 in²

Step-by-step explanation:

Diameter of semicircle = 24 in

We need to find area of semicircle.

The formula used to find area of semicircle is: [tex]Area=\frac{\pi r^2}{2}[/tex]

First we will find radius

We know that: radius = diameter/2 = 24/2 = 12

Now, finding area

[tex]Area=\frac{\pi r^2}{2}\\Area=\frac{3.14\times (12)^2}{2}\\Area=\frac{452.16}{2}\\Area=226.08\:in^2[/tex]

So, Area of semicircle = 226.08 in²

Answer:

0.65A = X

Step-by-step explanation:

Given that an item that regularly sells for A dollars is on sale for 35% off its regular price, to write an expression that shows the price in dollars after the discount the following equation must be proposed:

100 - 35 = 65

0.65A = Discount price

Therefore, if the regular price were $ 50, this equation would work as follows:

0.65 x 50 = X

32.5 = X

Answer:

3 pounds

Step-by-step explanation:

75% of 12= 9 pounds of vegetable that WERE on sale

100%-75%= 25% WERE NOT

25% of 12= 3 pounds

Step-by-step explanation:

3x + 2y = 9

- (3x + y = 6)

=> y = 3.

Therefore 3x + (3) = 6, 3x = 3, x = 1.

The solutions are x = 1 and y = 3.

Answer:

Triangle 1 is a right triangle

Triangle 2 is not a right triangle

Triangle 3 is a right triangle

Step-by-step explanation:

Triangle 1: 30^2 + 40^2 = 50^2

                 900  +  1600 =  2500

                             2500 =  2500

Triangle 2: 4^2 + 4^2 = 16^2

                     16 + 16 = 256

                           32 = 256

Triangle 3: 48^2 + 55^2 = 73^2
