Which of the following sets of numbers does V49 NOT belong?

Answer:

0.02275

Step-by-step explanation:

We use this z score formula to solve for this question

z-score is is z = (x-μ)/σ/√n

where x is the raw score

μ is the population mean

σ is the population standard deviation

From the above question,

x = 77

μ = 75

σ = 7

number of samples = 49

Hence, the z score = 77 - 75/ (7/√49)

= 2/(7/7)

= 2/1

= 2

Hence, the z score = 2

Using the z table to find probability

P(x<77) = 0.97725

P(x>77) = 1 - P(x<77)

= 1 - 0.97725

= 0.02275

Therefore, the probability that the same mean will be larger than 77 years

is 0.02275

Answer: Choice A

Ray PL and ray PQ

=======================================================

Explanation:

Opposite rays always have the same endpoint in common. So opposite rays start with the same letter.

Opposite rays also lay on the same geometric line. This means they point in complete opposite directions. Gluing together two opposite rays forms a line that extends forever in both directions.

Ray PQ points in one direction while ray PL points in the opposite direction. These are opposite rays.

Saying "ray PQ" is different from saying "ray QP". The order matters. This is because the first letter tells you the endpoint while the second letter is where the ray is aimed at (and where it goes off forever).

Answer:

C) f(2)=0 and g(-2)

Step-by-step explanation:

You start by looking at each graph and the given x values.

Check what value is at x=2 on the bue graph for your f(x), in this case it's 0. It's the same process for the red graph, g(x), which is 0.

Answer:

x=58/9 fraction x=6 4/9

Step-by-step explanation:

Answer:

x = 6.44 (rounded)

Step-by-step explanation:

First, combine like terms:

3x + 6x + 2 - 15 = 45

(3x + 6x) + (2 - 15) = 45

(9x) + (-13) = 45

9x - 13 = 45

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 13 to both sides:

9x - 13 (+13) = 45 (+13)

9x = 45 + 13

9x = 58

Next, divide 9 from both sides:

(9x)/9 = (58)/9

x = 58/9

x = 6.44

Answer:

The match last for 3 hours and 10 minutes.

Step-by-step explanation:

Match started at 10.25 am

Match ended at 1.35 pm

We need to find how long did the match last.

Minutes between 10.25 am to 11 am = 35 minutes

Minutes between 1 pm to 1.35 pm = 35 minutes

Time between 11 am to 1 pm = 2 hours

Time between 10.25 am and 1.35 pm is :

T = 2 hours 70 minutes

But 1 hour = 60 minutes

T = 2 hours (60+10) minutes

T = 3 hours 10 minutes

It means the match last for 3 hours and 10 minutes.

Answer:

the difference between the two fractions is 1/10

Step-by-step explanation:

when solving this problem you must switch the denominators to the same number. in this case thats 30. so 10*3 is 30 and 15*2 is 30. so then we multiply 7*3 to get 21 and 14*2 to get 24. so now we have 21/30 and 24/30, so then we compare. and we end up with 3/30, we simplify the answer to 1/10.

Answer:

180 days

Step-by-step explanation:

To solve for the least number of days all three will again be report to the principal, find the lowest common multiples of all three of them

Rachel will report to the principal every 9 days, Jessica every 12 days, and Richard every 15 days

Rachel (every 9 days) = 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180

Jessica (every 12 days) = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180

Richard (every 15 days) = 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180

The lowest common multiples of 9 days, 12 days, 15 days is 180 days

Therefore, the least number of days all three will report again to the principal is 180 days

D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.

E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.

Step-by-step explanation:

Which of the following statements are true? Select all that apply.

A.The expression 50ℎ represents the total charge for Rock the House Digital Designs.

B.The expression 75ℎ represents the total charge for Elegance Home Architects.

C.The cost for using Rock the House Digital Designs for an initial consultation only is $550.

D.If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.

E.If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.

Answer:

Rock the House Digital Designs charges $500.00 for the initial consultation with the Johnson family, plus $50.00 for every additional hour of work for the house plans. If they are hired for h hours, the total charge for Rock the House Digital Designs would be:

Total charge for Rock the House Digital Designs = 500 + 50h

Elegant Home Architects charge $75.00 per hour for the house plans, if they work for h hours, the total charge would be:

Total charge for Elegance Home Architects = 75h

A) Option A is not correct since the total charge for Rock the House Digital Designs is 500 + 50h

B) Option B is correct because the total charge for Elegance Home Architects = 75h

C) Option C is not correct, For an initial consultation, the cost for using Rock the House Digital Designs is $500

D) For a period of 15 hours:

Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(15) = $1250

Total charge for Elegance Home Architects = 75h = 75(15) = $1125

Option D is correct because Elegance home architect would be cheaper

E) For a period of 40 hours:

Total charge for Rock the House Digital Designs = 500 + 50h = 500 + 50(40) = $2500

Total charge for Elegance Home Architects = 75h = 75(40) = $3000

Option D is correct because Rock the House Digital Designs would be cheaper

Then, add the fractions and decimals together:

Convert 1/4 to a decimal, which is 0.25

Add the decimals together:

0.25 + 0.5

= 0.75

Convert this to a fraction:

0.75 = 3/4

Then, add together 20 and 3/4

Right angle = 90°

(x + 3) + (x - 1) + (x + 1) = 90

3x + 3 = 90, x = 29.

Supplementary angles = Angles that add up to 180°.

x + (x + 104) = 180

2x = 76, x = 38.

The value of x in fig.1 is 29 .

The value of x in fig.2 is 38 .

Given,

Figures having different angles .

1)

Right angle = 90°

(x + 3) + (x - 1) + (x + 1) = 90

3x + 3 = 90

x = 29.

2)

Supplementary angles = Angles that add up to 180°.

x + (x + 104) = 180

Answer:6m

Step-by-step explanation:

Square root 36m²

The required length of the side of the square is 6 meters.

Given that,
the area of the square is 36 square meters, what is the length (in meters) of one side in the square needs to be determined.

A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of the polygon, equilateral triangle, square, pentagon, etc

Here,
Since all the sides of the square are identical and the square is a polygon also.

Area of square = (side)²
we have given the area of a square, i.e. 36
36 = side²
side = √36
side = 6  (since √36 = 6)
Implies length of its side is 6 meters

Thus, the required length of the side of the square is 6 meters.
