Answer:

Multiplication

Step-by-step explanation:

This looks like the equation for the area of a rectangle.

Area = Lenght * Width

Given that the "l" variable and the "w" variable or next to each other without '/' or '\' , then we can safely say this a multiplication operation.

If there is no symbol between variables, it is assumed to be short-hand for multiplication instead of writing '*', '.', or 'x' in-between the variables.

Answer:

3905.12 feet

Step-by-step explanation:

we can form a triangle in order to use the Pythagorean theorem: a² + b² = h²

where:

a = distance covered on the ground

b = height above the Earth

3000² + 2500² = h²

h² = 9000000 + 6250000 = 15250000

h = √15250000

h = 3905.12 feet

Answer:

40%

Step-by-step explanation:

10 minutes late would mean 18 minutes late on the graph. The graph goes from 10-30 which creates a difference of 20. 8 divided by 20 equals 40 percent.

40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Given that,

Oliver is typically 10–30 minutes late for his shift at work.

The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.

John and Oliver are working a shift that starts at the same time. John always arrives 8 minutes late.

We have to determine,

What percentage of the time does Oliver arrive within 10 minutes of John's arrival time?

According to the question,

Oliver is typically 10–30 minutes late for his shift at work.

John and Oliver are working a shift that starts at the same time.

John always arrives 8 minutes late.

From the complete information, the probability distribution will be:

[tex]= \dfrac{1}{b-a}\\\\= \dfrac{1}{30-10}\\\\= \dfrac{1}{20}[/tex]

Here, John always arrives 8 minutes late.

Therefore,

The percentage of the time that Oliver arrives within 10 minutes of John's arrival time is,

[tex]\rm = 8 \times \dfrac{1}{20}\\\\= \dfrac{2}{5}\\\\= 0.4 \times 100 \\\\= 40 \ Percent[/tex]

Hence, 40 percent of the time does Oliver arrives within 10 minutes of John's arrival time.

Answer: A

Step-by-step explanation:

To add fractions, we want to make sure there is a common denominator. After that, we can add the numerator.

[tex]\frac{8}{z^2+6z+9} +\frac{5}{z^2-9}[/tex]                 [factor denominator]

[tex]\frac{8}{(z+3)(z+3)} +\frac{5}{(z+3)(z-3)}[/tex]      [multiply first fractioni by z-3 and second by z+3]

[tex]\frac{8(z-3)}{(z+3)^2(z-3)} +\frac{5(z+3)}{(z+3)^2(z-3)}[/tex]   [distribute by FOIL]

[tex]\frac{8z-24}{(z+3)^2(z-3)} +\frac{5z+15}{(z+3)^2(z-3)}[/tex]   [add]

[tex]\frac{13x-9}{(z+3)^2(z-3)}[/tex]

This is the same as A. Therefore, A is our answer.

Answer:

cp of 55 shares = 3.50 * 55 = 192.5

commission amount = 1% *192.5 = 1.925

Total invest = 192.5 + 1.925 = 194.425

sp of 1 share = 2

sp of 55 share = 2*55 = 110

Earning from shares = 110

since earning is less than invest, Laura has loss of (194.425 - 110) = 84.425

Laura has a loss of $84.425 for the cost price of $192.5.

Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Cost price of 55 shares = 3.50 x 55 = 192.5

Commission amount = 1% *192.5 = 1.925

Total invest = 192.5 + 1.925 = 194.425

The selling price of 1 share = 2

The selling price  of 55 share = 2*55 = 110

Earning from shares = 110

Since earnings are less than investment, Laura has a loss of (194.425 - 110) = $84.425

Therefore, Laura has a loss of $84.425 for the cost price of $192.5.

Step-by-step explanation:

The 2 given angles are same- side interior angles and are supplementary, thus

9x - 4 + 5x + 16 = 180, that is

14x + 12 = 180 ( subtract 12 from both sides )

14x = 168 ( divide both sides by 14 )

x = 12

Answer:

For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Step-by-step explanation:

The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.

A linear regression is represented as [tex]^\wedge y = mx + c[/tex].

The true option is:  E. For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Given that:

[tex]^\wedge S = 0.5 + 1.1L[/tex]

From the general linear equation, we have:

[tex]1.1 \to[/tex] The slope

[tex]0.5 \to[/tex] The y-intercept

The slope is the difference between the sales price of one listing and the next.

From the question, we understand that the listed amount is in 100,000's.

This means that there is an increment of [tex]\$1.1 \times 100000[/tex] between the sales price of concurrent listing

So, we have:

[tex]\$1.1 \times 100000 =\$110000[/tex]

From the list of given options (see attachment), we can then conclude that (e) is correct.

Hence, for each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Answer:

26°

Step-by-step explanation:

The angle 5 is equal to angle 154° as these are both corresponding angles and corresponding angles are equal.

Angles on a straight line equal 180°, so if we take 154° from 180° we get angle 4, which is 26°

I hope that helped!

XY and WZ are parallel.

Angle 1 + 154° = 180° (Linear pair)

→ Angle 1 = 180 - 154

→ Angle 1 = 26°

Now, Angle 4 = Angle 1 (Alternative interior angles)

→ Angle 4 = 26°

Hence, we got the answer.

Answer:

Blue, if you look, they both are close, but due to the pathagrium theory blue is longer.

Step-by-step explanation:

Answer:

Red is longer

Step-by-step explanation:

With the distance equation formula, you can find this. The distance equation formula is d=[tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} } \\[/tex]. (x1,y1)(x2,y2) are the coordinates of each individual point.

If you turn the grid into a graph, red's points would be (0,0)(3,3)

Blue's points would be (0,3)(-1,-1). Using the distance formula blue is [tex]\sqrt{17}[/tex].

The red is [tex]\sqrt{18}[/tex], so red is longer.
