Answer:

The answer is B

Step-by-step explanation:

These are in Y = MX + B form

The first line has a positive slope, so the coefficient "M" is positive.

The second line has a negative slope, so the coefficient "M" is negative.

The first line has a filled in dot at Y = 2.

Since it's to the left (less than X direction)...

X <= 0

The second has an empty circle at Y = 4.

Since the line goes to the right....

0 < X

Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.

From these things, we can infer that B is the correct answer.

A product goes from $25 to $27 in price.

Pachacha [2.7K]

(original price) x (percent) = (final price)
25 x (percent) = 27 
percent = 27/25 
percent = 1.08 
It is 1.08 times greater, which is 108%, so there is an 8% increase.
therefore the correct answer is opt B.

Hope it helps!!

Sphinxa [80]

Answer:

Option B) 0.2143

Step-by-step explanation:

We are given the following in the question:

Numbers of exposures(x): 4,3,7

We have to find the maximum likelihood estimate of p.

Formula:

$\hat{p} = \dfrac{n}{\sum x_i}$

Putting the values, we get,

$\hat{p} = \dfrac{3}{3+4+7} = \dfrac{3}{14} = 0.2143$

Thus, the correct answer is

Option B) 0.2143

USPshnik [31]

Answer:

1.84metres

Step-by-step explanation:

convert 76cm to metres

76/100=0.76m

convert 8cm to metres

8/100=0.08m

therefore we have,

1+0.76+0.08=1.84metres

Math help please show work thanks

Rufina [12.5K]

Answer:

The curve surface area(CSA) of a cylinder is 2πrh.

Since diameter=1.5 in.

radius=diameter/2

=1.5/2 in.

=0.75 in.

And, the height of the bottle is 5 in.

Now,

CSA=2πrh

=2π*0.75*5 in^2

=15π/2 or 23.56 in^2

The size of the label needed to cover the entire bottle is 15π/2 or 23.56 in^2.
