Step-by-step explanation:

Which type of graph would allow us to quickly see how many months between 100 and 200 students were treated?

Histogram is a type of graph where bars of different heights are used to show continuous data. The difference between the intervals is called class marks.

So, here the best graph can be histogram as it will properly show the intervals.

PilotLPTM [1.2K]

Answer:

50% is the answer.

Step-by-step explanation:

All three persons have different blood groups.

Mary has O blood type.

Her husband has B blood type.

Her father in law has A blood type.

As everyone has different blood groups and the child's group depends on parents blood groups so we have 2 options left.

Hence, the probability that the child will have type O blood is = $\frac{1}{2}$ =50%

If the sine of an angle equals to {2}/{5}, then the tangent of the angle could be:

Leona [35]

Answer:

If the sine of an angle equals to {2}/{5}, then the tangent of the angle could be:

5. $\frac{2}{\sqrt{21} }$

Step-by-step explanation:

Imagine a triangle

The sine of an angle is equal to the length of the opposite leg over the hypotenuse.
HINT: SOHCAHTOA

To find the adjacent leg (a):

Using the pythagorean theorem: $a^{2} + b^{2} =c^{2}$

- a and b are the lenght of the sides and c is the hypotenuse

we know one side and the hypotenuse. Therefore plugging into the formula we get:

$a^{2} + 2^{2} =5^{2}$

where a is the adjacent leg of the triangle, solving for a we get:

$a^{2} =5^{2}- 2^{2}$

$a^{2} = 21$

$a = \sqrt{21}$

To find the tangent of the angle:

Since tangent is opposite leg over the adjacent leg:

tan θ = $\frac{2}{\sqrt{21} }$

(X+5)(x+4) write answer in standard form

lisov135 [29]

Answer:

I'm not sure if you meant to capitalize the first "x". If you did, then the correct answer is:

Xx+4X+5x+20

If you didn't, the answer is:

x^2+5x+20

Work:

1) X*x=Xx

2) X*4=4X

3) 5*x=5x

4) 5*4=20
