Answer:

C. Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores.

Step-by-step explanation:

Mean Absolute Deviation is one of the Statistical measures which we can you to determine the variation that exist amongst a given set of data

Mean Absolute Deviation can be defined as how far or the distance between one set of data to another set of data.

The smaller the Mean Standard Deviation, the lower the degree of variation in the set of data. The data is less spread out

The larger the Mean Standard Deviation, the higher the degree of variation in the set of data. The data is Largely spread out

We are told in the question that:

Mrs. Alvarez's scores had a lower mean absolute deviation than Mr. Crawford's scores. Our conclusion would be that Mrs. Alvarez's scores were less spread out than Mr. Crawford's scores.

Step-by-step explanation:

Answer:

Given: An Angle in the figure is right angle. Its measure = 90°

So,

∠2 = 90° ( vertically opposite angles are equal )

∠1 + ∠2 = 180° ( Linear Pair )

∠1 = 180 - 90

∠1 = 90°

So, ∠1 and ∠2 are

Right angles because measure of both angles are 90°.

Adjacent angles because both a common arm and a common vertex.

Supplementary angles because sum of both angles is 180°.

Answer:

Step-by-step explanation:

Average speed = distance/time

Trip to dry dock

Let x be the velocity

Time = 2hours

Distance = average speed ×time

Distance = x×2

Distance = 2x

Return trip

Velocity = x-5 (5 miles per hour faster on the trip there than on the return trip)

Time = 3hrs

Distance = 3(x-5)

Since the distance is the same both to and fro;

2x = 3(x-5)

2x = 3x -15

2x-3x = -15

-x = 15

x = 15

Hence the aircraft carrier's average speed on the outbound trip is 15miles/hour

The answer is

[tex] \huge y = 5[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (3,-5) and slope 0

We have

[tex]y + 5 = 0(x - 3) \\ y + 5 = 0 \\ y = 5[/tex]

We have the final answer as

[tex]y = 5[/tex]

Answer:

$500 per week.

Step-by-step explanation:

Let Cameron earns $x as a tutor.

As his sister earns one and a half times as much as a tutor, so, his sister earns $1.5x.

Since the weekly wage of Cameron's sister is $250 more than Cameron, so

[tex]1.5x=x+250[/tex]

[tex]\Rightarrow 1.5x-x=250[/tex]

[tex]\Rightarrow 0.5x=250[/tex]

[tex]\Rightarrow x=500.[/tex]

Hence, the weekly earning of Cameron is $500.

D

if u use deductive reasoning you'll know. so u know looking at the line it's a positive slope cause the line is going up and u know the y intercept is positve 1 so u know it will be +1 knowing this and going through the answer choices D is the only one that fits that!

The correct explanation of the graph is;

y = 3/2 x + 1

Option D is true.

What is Equation of line?

The equation of line with slope m and y intercept at point b is given as;

y = mx + b

Given that;

The graph is shown in figure.

Two points on the graph are (2, 4) and (4, 7).

Now, Take two points on graph and find the slope of the graph as,

Two points on the graph are (2, 4) and (4, 7).

Hence, Slope of graph = (7 - 4) / (4 - 2)

                                   = 3/2

Thus, Slope of graph is 3/2.

Since the slope of graph is same as slope of equation.

Hence, In option D;

The equation is given as;

y = 3/2 x + 1

Slope of equation is find as differentiate with respect to x,

Slope of equation is;

dy/dx = m = 3/2

So, The correct explanation of the graph is;

y = 3/2 x + 1

X is about 14.1

Step-by-step explanation:

Hi!

In order to solve this problem, we just have to take the square root of both sides:

x²=200

x times itself should equal 200.

And the answer is

x≈14.1

Answer:

true

Step-by-step explanation:

Another way to solve a direct variation equation is by setting up a proportion.

Molly’s monthly payment by using the Bankrate calculator is $286 per month.

It is given that

The downpayment Molly has = $2500.

Interest rate APR = 1.9%

Cash allowance by dealer = $500

Selling price = $25,495

Loan tenure N= 7 years

Amount of loan needed = 25495-2500-500 = $22495

An equated monthly installment (EMI) is a set monthly payment provided by a borrower to a creditor on a set day, each month.

The EMI or monthly payment will be calculated by the following formula,

[tex]EMI = \frac{P.\frac{APR}{12} .(1+\frac{APR}{12})^N }{(1+\frac{APR}{12})^N-1 }[/tex]

Put APR =0.019(decimal value of APR)

N = 7

EMI = $286 per month.

Therefore, Molly’s monthly payment by using the Bankrate calculator is $286 per month.

Answer:

speed is 0.01 miles per minute

Step-by-step explanation:

We know speed = distance/time

since we need speed in miles per minute we need to convert KM into miles

and hours in minutes

--------------------------------------------------------

distance = 5 km

1 km = 0.621371 miles

5KM = 5*0.621371 miles = 3.10686 miles = 3.12 miles(rounded to nearest hundredth)

1 hour = 60 minutes

4.5 hours = 4.5*60 minutes = 270 minutes

speed = distance in KM/time in minutes = 3.12 miles/270 minutes

speed = 0.012 miles per minute

rounding the answer to  the nearest hundredth

speed is 0.01 miles per minute
